[0040] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0041] Before providing a detailed description of the cell selection method provided in the embodiments of this application, a brief introduction to the mobile communication system involved in the embodiments of this application will be given first.

[0042] Please refer to Figure 1 This illustration shows a schematic diagram of a mobile communication system provided in one embodiment of this application. The network architecture may include: terminal device 10, network device 20, and core network device 30.

[0043] Terminal equipment 10 can refer to UE (User Equipment), access terminal equipment, user unit, user station, mobile station, mobile station, remote station, remote terminal equipment, mobile device, wireless communication equipment, user agent, or user device. Optionally, terminal equipment 10 can also be a cellular phone, cordless phone, SIP (Session Initiation Protocol) phone, WLL (Wireless Local Loop) station, PDA (Personal Digital Assistant), handheld device with wireless communication function, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, terminal equipment in 5GS (5th Generation System), or terminal equipment in the future evolved PLMN (Public Land Mobile Network), etc., and this application embodiment is not limited to these. For ease of description, the devices mentioned above are collectively referred to as terminal equipment. The number of terminal equipment 10 is usually multiple, and one or more terminal equipment 10 can be distributed within the cell managed by each network device 20.

[0044] Network device 20 is a device deployed in an access network to provide wireless communication functionality to terminal device 10. Network device 20 can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the name of the device with network device functionality may differ; for example, in a 5G NR system, it is called a gNodeB or gNB. As communication technologies evolve, the name "network device" may change. For ease of description, in this embodiment, the aforementioned devices providing wireless communication functionality to terminal device 10 are collectively referred to as network devices. Optionally, a communication relationship can be established between terminal device 10 and core network device 30 through network device 20. For example, in an LTE (Long Term Evolution) system, network device 20 can be one or more eNodeBs within an EUTRAN (Evolved Universal Terrestrial Radio Access Network); in a 5G NR system, network device 20 can be one or more gNBs within a RAN (Radio Access Network). In the embodiments of this application, unless otherwise specified, the network device refers to network device 20.

[0045] The core network equipment 30 primarily functions to provide user connectivity, manage users, and carry out service delivery, serving as an interface to external networks. For example, core network equipment in a 5G NR system may include AMF (Access and Mobility Management Function) entities, UPF (User Plane Function) entities, and SMF (Session Management Function) entities.

[0046] In one example, network device 20 communicates with core network device 30 via some air interface technology, such as the NG interface in a 5G NR system. Network device 20 also communicates with terminal device 10 via some air interface technology, such as the Uu interface.

[0047] The "5G NR system" in this application embodiment can also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in this application embodiment can be applied to 5G NR systems, as well as subsequent evolution systems of 5G NR systems.

[0048] Communication systems typically support cell selection for terminal devices. When a user needs to use network services and selects a cell, the system connects the user to the selected cell via a communication link, i.e., performs the cell selection process. Therefore, the terminal device can switch from an idle state to the cell of the first network device.

[0049] Communication systems typically support cell handover for terminal devices. When a user needing network services moves from one cell to another, or due to adjustments in wireless transmission load, activation maintenance, equipment failure, or other reasons, the system transfers the user's communication link from the original cell to the new cell to ensure communication continuity and service quality; this is known as cell handover. Therefore, a terminal device can switch from the cell of a first network device to the cell of a second network device.

[0050] Figure 2 A flowchart illustrating a cell selection method provided in an exemplary embodiment of this application is shown. This embodiment applies the method to a terminal device. The method includes:

[0051] Step 201: The terminal device performs cell selection or cell reselection based on model-related information of the application model supported by at least one cell.

[0052] In one possible implementation, the application model refers to a model applied to the communication system. The application model includes at least one of the following: Artificial Intelligence (AI) model, machine learning model, authentication model, encryption model, and decryption model. This application does not limit the scope of the application model.

[0053] Optionally, an AI model refers to a model that predicts and processes certain information, data, or decisions during mobile communication; an authentication model refers to a model that authenticates certain access information or input data during mobile communication; an encryption model refers to a model that encrypts certain signaling and / or data during mobile communication; and a decryption model refers to a model that decrypts certain signaling and / or data during mobile communication.

[0054] In the cell selection process, the application model supported by a cell refers to the application model that at least one of the n cells searched can support.

[0055] During cell reselection, the application model supported by the cell refers to the application model that the serving cell and / or at least one neighboring cell can support.

[0056] In one possible implementation, the model-related information of the application model includes at least one of the following: model identification information of the application model, priority information corresponding to the application model, and precision level information corresponding to the application model. This application does not limit the specific details of these components. The model identification information refers to the identification information used to uniquely identify the application model; the priority information refers to the priority information of the application model, which may differ for the same application model on different terminal devices; and the precision level information refers to the computational precision information of different application models.

[0057] For example, when a terminal device is powered on or enters a coverage area from a blind spot, it searches for allowed frequencies in the Public Land Mobile Network (PLMN) and selects a suitable cell to camp on from at least one cell.

[0058] Cell reselection refers to the process by which a terminal device, in idle or inactive mode, monitors the signal strength, quality, and application model information of neighboring and serving cells, and selects a cell that meets the cell reselection rules to provide service. Cell reselection maximizes the chances of a terminal device in idle or inactive mode staying in a suitable cell. The serving cell is the cell where the terminal device is currently located.

[0059] Neighboring cells are those that are relative to the serving cell. Simply put, they are other cells around the serving cell. The terminal device determines one or more neighboring cells through the measurement process. Optionally, in order to help the terminal device quickly measure neighboring cells, the serving cell will inform the terminal device of the frequency point information, synchronization signal window, and other information of the neighboring cells through system broadcast messages, which is used to assist the terminal device in measuring neighboring cells.

[0060] In one possible implementation, the terminal device may be pre-configured with some cell or frequency measurement auxiliary information to assist the terminal device in performing cell measurements.

[0061] In summary, the technical solution provided in this application allows the terminal device to select or reselect a cell based on model-related information of at least one application model supported by the cell. This technical solution enables the terminal device to select a cell that supports the application model required by the terminal device, thereby obtaining more accurate cell selection or reselection results and improving the user service experience.

[0062] Figure 3 A flowchart illustrating a cell selection method provided in an exemplary embodiment of this application is shown. This embodiment applies the method to a terminal device. The method includes:

[0063] Step 301: The terminal device determines the target model identifier set.

[0064] For example, the target model identifier set refers to the set of identifier information of the application model that the terminal device expects to obtain, and the target model identifier set contains the identifier information of at least one application model.

[0065] Optionally, the target model identifier set determined by the terminal device can be obtained through the terminal device's non-access layer (NAS), or through the terminal device's access layer (AS), or through the network device configuration process; this application does not limit this.

[0066] Step 302: The terminal device selects a cell based on the model identifier information of the application model supported by the cell and the target model identifier set.

[0067] The model identification information of an application model refers to the identification information used to uniquely identify the application model.

[0068] For example, the terminal device makes a judgment based on the model identification information of the application model supported by the cell and the target model identification set. If the terminal device finds the target cell, the terminal device selects the target cell to camp on.

[0069] The terminal device selects a cell based on the model identifier information of the application model supported by the cell and the target model identifier set, including at least one of the following four methods:

[0070] Method 1: Determine at least one cell in the searched cell-supported model identifier set that has the largest number of intersection elements with the target model identifier set as a candidate cell, and determine the target cell from the candidate cells according to the S criterion.

[0071] For example, the target cell refers to the cell that the terminal device can camp on among the cells searched by the terminal device.

[0072] The terminal device determines the target model identifier set and the application model identifier set supported by the cells searched by the terminal device. By comparison, at least one cell in the model identifier set supported by the searched cells with the largest number of intersection elements with the target model identifier set is selected as a candidate cell. Within the candidate cell range, the terminal device determines the target cell according to the S criterion.

[0073] Within the candidate cell range, if a cell meets the S criterion, it is considered a suitable cell, selected as the target cell, and the cell is chosen for camping. If a cell does not meet the S criterion, the process continues to evaluate the next candidate cell until a candidate cell meets the S criterion.

[0074] If none of the candidate cells within the candidate cell range meet the S criterion, then the terminal device selects a cell from the cells it has searched. Within the cell range searched by the terminal device, the terminal device determines the target cell according to the S criterion and selects that cell to camp on.

[0075] The technical solutions provided in this application can be applied to NTN systems and cellular network systems.

[0076] The S criterion refers to a basic condition for a terminal device to be able to normally camp on a cell. It means that the cell can provide a service level that meets the S criterion. In other words, only when the measurement and evaluation results of a cell meet the S criterion can it become a target cell for cell selection.

[0077] The S criterion stipulates:

[0078] Srxlev > 0 and Squal > 0

[0079] Where Srxlev is the received power during cell search; Squal is the received signal quality during cell search; the expressions for Srxlev and Squal are shown below:

[0080] Srxlev=Qrxlevmeas-(Qrxlevmin+Qrxlevminoffset)-Pcompensation-Qoffsettemp

[0081] Squal=Qqualmeas-(Qqualmin+Qqualminoffset)-Qoffsettemp

[0082] The meanings of the parameters appearing in the above expression are explained as follows:

[0083] Qrxlevmeas is the Reference Signal Receiving Power (RSRP) calculated by the terminal device based on actual measurements.

[0084] Qqualmeas is the reference signal receiving quality (RSRQ) obtained by actual measurement and calculation by the terminal device.

[0085] Qrxlevmin is the minimum receive power (RSRP) required by the network device.

[0086] Qqualmin is the minimum signal quality (RSRQ) required by a network device.

[0087] Qrxlevminoffset and Qqualminoffset are offsets to prevent the ping-pong effect caused by radio environment fluctuations between two Public Land Mobile Networks (PLMNs). In other words, Qrxlevminoffset and Qqualminoffset are the offsets to Qrxlevmin and Qqualmin that a terminal device needs to consider when periodically searching for a higher priority PLMN while residing on a Visited Public Land Mobile Network (VPLMN).

[0088] Pcompensation refers to power compensation, such as when the maximum allowable transmit power of a network device is greater than the maximum uplink transmit power determined by the terminal device's own capabilities, resulting in power compensation due to the terminal device's low power.

[0089] Qoffsettemp is only used in special scenarios and is not applicable under normal circumstances, such as the "Chiba Problem" scenario.

[0090] Since RSRP represents the reference received signal power, Qrxlevmeas - (Qrxlevmin + Qrxlevminoffset) indicates downlink received signal quality, and Pcompensation indicates uplink transmitted signal quality, Srxlev, relative to RSRP, is an assessment value that comprehensively considers both uplink and downlink signal power strength and represents the service quality a cell can provide. RSRQ, as a signal quality metric that comprehensively considers RSRP and total received power (including interference and noise), provides a more reliable assessment basis than RSRP; therefore, Squal also represents the cell's service level. Srxlev and Squal can comprehensively assess the service quality a cell can provide. Therefore, the S criterion becomes a fundamental evaluation condition for whether a cell is suitable for camping.

[0091] In one possible implementation, when selecting a cell, the terminal device measures the Qrxlevmeas and Qqualmeas values ​​of the searched cell. It then obtains other parameters from the S-criteria formula based on the cell's system information and its own capability level, calculates Srxlev and Squal, and compares them with 0. If Srxlev > 0 and Squal > 0, meaning the cell meets the S-criteria, the terminal device considers the cell to meet the signal quality requirements for cell selection and can select it as the cell to camp on. If the cell's system information broadcasts that it is allowed to camp on that cell, the terminal will choose to camp on that cell.

[0092] For example, such as Figure 4As shown, the terminal device determines the target model identifier set. The terminal device searches for cell A and cell B. The model identifier set supported by cell A includes AI model identifier 1, and the model identifier set supported by cell B includes AI model identifier 2, AI model identifier 3, and AI model identifier 4. By comparison, cell B has the most intersection elements with the target model identifier set, so cell B is selected as a candidate cell. The S criterion is then used to determine whether cell B can be used as the target cell for camping.

[0093] Method 2: Determine at least one cell in the set of model identifiers supported by the searched cells that has an intersection with the target model identifier set that satisfies the first threshold as a candidate cell, and determine the target cell from the candidate cells according to the S criterion.

[0094] For example, the first threshold is a default value or is configured via a network device.

[0095] The terminal device determines the set of model identifiers supported by the searched cells. By comparing it with the target set of model identifiers determined by the terminal device, if the number of intersection elements between the set of model identifiers supported by the cell and the target set of model identifiers meets the first threshold, the cell is determined as a candidate cell. Within the candidate cell range, the terminal device determines the target cell according to the S criterion.

[0096] Within the candidate cell range, if a cell meets the S criterion, it is considered a suitable cell, selected as the target cell, and the cell is chosen for camping. If a cell does not meet the S criterion, the process continues to evaluate the next candidate cell until a candidate cell meets the S criterion.

[0097] If none of the candidate cells within the candidate cell range meet the S criterion, then the terminal device selects a cell from the cells it has searched. Within the cell range searched by the terminal device, the terminal device determines the target cell according to the S criterion and selects that cell to camp on.

[0098] For example, such as Figure 4 As shown, the terminal device determines the target model identifier set. The terminal device searches for cell A and cell B. The model identifier set supported by cell A includes AI model identifier 1, and the model identifier set supported by cell B includes AI model identifier 2, AI model identifier 3, and AI model identifier 4. By comparison, the number of intersection elements between cell B and the target model identifier set meets the preset first threshold 2. Therefore, cell B is selected as a candidate cell, and the S criterion is used to determine whether cell B can be used as the target cell for camping.

[0099] Method 3: Select the first application model identifier with the highest priority in the target model identifier set, determine at least one cell that supports the first application model identifier as a candidate cell, and determine the target cell from the candidate cells according to the S criterion.

[0100] Optionally, the priority of the application model identifier in the target model identifier set determined by the terminal device can be provided by the NAS of the terminal device, or determined based on the AS of the terminal device, or obtained by the terminal device from the network device configuration process. This application does not limit this.

[0101] For example, the first application model identifier with the highest priority is determined in the target model identifier set, and at least one cell that supports the first application model identifier is determined as a candidate cell among the cells searched by the terminal device. Within the candidate cell range, the terminal device determines the target cell according to the S criterion.

[0102] Within the candidate cell range, if a cell meets the S criterion, it is considered a suitable cell, selected as the target cell, and the cell is chosen for camping. If a cell does not meet the S criterion, the process continues to evaluate the next candidate cell until a candidate cell meets the S criterion.

[0103] In one possible implementation, the first application model identifier with the highest priority in the target model identifier set is selected. If it is determined that none of the searched cells support the first application model identifier, the terminal device determines the target cell from the searched cells according to the S criterion.

[0104] For example, if none of the candidate cells within the candidate cell range meet the S criterion, then cell selection is performed among the cells searched by the terminal device. Within the cell range searched by the terminal device, the terminal device determines the target cell according to the S criterion and selects that cell to camp on.

[0105] For example, such as Figure 4 As shown, the terminal device determines a target model identifier set, where AI model identifier 1 has a priority of 1, AI model identifier 2 has a priority of 2, AI model identifier 3 has a priority of 3, and AI model identifier 4 has a priority of 4. AI model identifier 1 has the highest priority in the target model identifier set. The terminal device searches for cells A and B. Among the cells searched, only cell A supports the highest priority AI model identifier 1. Therefore, cell A is selected as a candidate cell, and the S criterion is used to determine whether cell A can be used as a target cell for camping. If neither cell A nor cell B searched by the terminal device supports the highest priority AI model identifier, the terminal device does not consider the model identifier priority and directly judges cell A and cell B according to the S criterion.

[0106] Method 4: Select the second application model identifier with the highest priority (i) in the target model identifier set, determine at least one cell that supports the second application model identifier as a candidate cell, and determine the target cell from the candidate cells according to the S criterion; otherwise, if it is determined that none of the searched cells support the second application model identifier, select the third application model identifier with the highest priority (i+1) in the target model identifier set, determine at least one cell that supports the third application model identifier as a candidate cell, and determine the target cell from the candidate cells according to the S criterion; otherwise, repeat the previous step until a target cell is determined, where the initial value of i is 1.

[0107] In one possible implementation, the terminal device selects the second application model identifier with the highest priority (i) from the target model identifier set. The terminal device then determines at least one cell that supports the second application model identifier as a candidate cell, and determines the target cell from the candidate cells according to the S criterion. Otherwise, if it is determined that none of the searched cells support the second application model identifier, the terminal device selects the third application model identifier with the highest priority (i+1) from the target model identifier set, determines at least one cell that supports the third application model identifier as a candidate cell, and determines the target cell from the candidate cells according to the S criterion. If none of the searched cells support either the second or third application model identifier, the terminal device determines the target cell from all the searched cells according to the S criterion.

[0108] In one possible implementation, the terminal device selects the second application model identifier with the highest priority in the target model identifier set, determines at least one cell that supports the second application model identifier as a candidate cell, and determines the target cell from the candidate cells according to the S criterion; otherwise, if it is determined that none of the searched cells support the second application model identifier, the terminal device selects the third application model identifier with the highest priority in the target model identifier set, determines at least one cell that supports the third application model identifier as a candidate cell, and determines the target cell from the candidate cells according to the S criterion; otherwise, if it is determined that none of the searched cells support the third application model identifier, the terminal device selects the fourth application model identifier with the highest priority in the target model identifier set, and so on, selecting sequentially according to the priority order of the application model identifiers in the target model identifier set until a target cell is determined and designated as a candidate cell. Within the candidate cell range, the terminal device determines the target cell according to the S criterion.

[0109] Within the candidate cell range, if a cell meets the S criterion, it is considered a suitable cell, selected as the target cell, and the cell is chosen for camping. If a cell does not meet the S criterion, the process continues to evaluate the next candidate cell until a candidate cell meets the S criterion.

[0110] In one possible implementation, if none of the cells searched by the terminal device support any of the application model identifiers included in the target model identifier set, the terminal device determines the target cell from all the cells searched according to the S criterion.

[0111] For example, if none of the candidate cells within the candidate cell range meet the S criterion, then cell selection is performed among the cells searched by the terminal device. Within the cell range searched by the terminal device, the terminal device determines the target cell according to the S criterion and selects that cell to camp on.

[0112] For example, such as Figure 4 As shown, the terminal device determines the target model identifier set, where the model identifier priority corresponding to AI model identifier 1 is 1, and the model priority corresponding to AI model identifier 1 is the highest. If cell A found by the terminal device does not meet the S criterion, the second highest priority AI model identifier 2 is selected. Based on the judgment, cell B supports the second highest priority AI model identifier 2, so cell B is selected as a candidate cell, and the S criterion is used to determine whether cell B can be used as the target cell for camping.

[0113] If the cell searched by the terminal device does not support the highest priority AI model identifier 1 or the second highest priority AI model identifier 2, then the previous step is executed again, and the third highest priority AI model identifier 3 is selected for judgment; if none of the cells searched by the terminal device support any model identifier in the target model identifier set, then the terminal device does not consider the priority of the model identifier and directly judges the searched cells according to the S criterion.

[0114] In summary, the technical solution provided in this application embodiment involves a terminal device determining candidate cells based on the relationship between the identifier information of the application models supported by the searched cells and the target model identifier set. Within the determined candidate cell range, the terminal device then determines the target cell according to the S criterion. This technical solution enables the terminal device to select cells that support the application models required by the terminal device, thereby obtaining more accurate cell selection results and improving the user service experience.

[0115] Figure 5 A flowchart illustrating a cell reselection method provided in an exemplary embodiment of this application is shown. This embodiment applies the method to a terminal device. The method includes:

[0116] Step 501: The terminal device determines the target model identifier set.

[0117] For example, the target model identifier set refers to the set of identifier information of the application model that the terminal device expects to obtain, and the target model identifier set contains the identifier information of at least one application model.

[0118] Optionally, the target model identifier set determined by the terminal device can be obtained through the NAS of the terminal device, or the AS of the terminal device, or through the network device configuration process, and this application does not limit this.

[0119] Step 502: The terminal device performs cell reselection based on the model identifier information of the application model supported by the cell and the target model identifier set.

[0120] The identification information of an application model refers to the information used to uniquely identify the application model.

[0121] The terminal device performs cell reselection based on the identification information of the application model supported by the serving cell and / or at least one neighboring cell and the target model identification set.

[0122] The terminal device performs cell reselection based on the model identifier information of the application model supported by the cell and the target model identifier set, including at least one of the following four methods:

[0123] Method 1: Determine at least one neighboring cell with the largest number of intersection elements with the target model identifier set in the set of model identifiers supported by the neighboring cells as a candidate neighboring cell, and determine the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method.

[0124] For example, the target reselection cell refers to a cell among neighboring cells that the terminal device can reselect, camp on, and that is different from the currently serving cell.

[0125] The terminal device determines the target model identifier set and the application model identifier set supported by the neighboring cells measured by the terminal device. By comparison, at least one neighboring cell with the most intersection elements with the target model identifier set in the neighboring cell's supported model identifier set is selected as a candidate neighboring cell. Within the candidate neighboring cell range, the terminal device determines the target reselection cell according to the absolute frequency priority cell reselection method.

[0126] Within the candidate neighbor cell range, the terminal device performs cell reselection according to the absolute frequency priority cell reselection method. If the neighbor cell meets the requirements, it is considered a suitable neighbor cell, and the neighbor cell is selected as the target reselection cell and camped on. If the neighbor cell does not meet the requirements, the next candidate neighbor cell is evaluated until a candidate neighbor cell meets the requirements.

[0127] If none of the candidate neighboring cells within the candidate neighboring cell range meet the requirements, then cell reselection is performed in all neighboring cells measured by the terminal device. Within the range of all neighboring cells measured by the terminal device, the terminal device determines the target reselection cell according to the absolute frequency priority cell reselection method and selects that neighboring cell for camping.

[0128] For example, the absolute frequency priority cell reselection method includes co-frequency neighbor cell reselection criteria and inter-frequency neighbor cell reselection criteria. Co-frequency neighbor cells refer to neighbor cells with the same frequency as the serving cell; inter-frequency neighbor cells refer to neighbor cells with a different frequency than the serving cell.

[0129] The reselection criterion for neighboring cells on the same frequency, also known as the R criterion, is as follows:

[0130] Rs = Qmeas, s + Qhyst - Qoffset temp

[0131] Rn=Qmeas,n-Qoffset-Qoffset temp

[0132] In the formula, Rs is the R value of the serving cell, Rn is the R value of the neighboring cells, Qhyst is the lag value of the ranking criteria, Qmeas is the RSRP value of the reselected cell during cell reselection, and Qoffset represents the Qneas,n of the cell when a suitable cell exists among the neighboring cells. When no suitable cell exists among the neighboring cells, Qneas,n is 0. temp This is a temporary offset.

[0133] When the terminal device determines the target cell for reselection based on the absolute frequency priority cell reselection method, if the terminal device's neighboring cells include co-frequency neighboring cells, the terminal device selects the neighboring cell with the highest R value among the co-frequency neighboring cells as the target cell for reselection and camps on it.

[0134] Inter-frequency neighbor cell reselection refers to the process of reselecting a cell among multiple inter-frequency neighbor cells. If a high-priority inter-frequency neighbor cell exists that meets the high-priority cell reselection criteria, the terminal device will reselect to the high-priority inter-frequency neighbor cell. If no suitable high-priority inter-frequency neighbor cell exists, the terminal device will reselect to a cell in the same frequency or an inter-frequency neighbor cell of the same priority according to the same-frequency neighbor cell reselection criteria. If no suitable high-priority inter-frequency neighbor cell, same-frequency neighbor cell, or inter-frequency neighbor cell of the same priority exists, the terminal device will reselect to a low-priority inter-frequency neighbor cell according to the low-priority cell reselection criteria.

[0135] For example, such as Figure 4As shown, the terminal device determines the target model identifier set. The terminal device measures and obtains neighboring cell C and neighboring cell D. The model identifier set supported by neighboring cell C includes AI model identifier 3. The model identifier set supported by neighboring cell D of the terminal device includes AI model identifier 1 and AI model identifier 4. By comparison, neighboring cell D has the most intersection elements with the target model identifier set. Therefore, neighboring cell D is selected as a candidate neighboring cell. The absolute frequency priority cell reselection method is used to determine whether neighboring cell D can be used as the target reselection cell for camping.

[0136] Method 2: Determine at least one neighboring cell in the set of model identifiers supported by the neighboring cell that has an intersection with the target model identifier set that satisfies the second threshold as a candidate neighboring cell, and determine the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method.

[0137] For example, the second threshold is a default value or is configured via a network device.

[0138] The terminal device determines the set of model identifiers supported by the neighboring cell, and compares them with the target model identifier set of the terminal device. If the number of intersection elements between the set of model identifiers supported by the neighboring cell and the target model identifier set meets the second threshold, the neighboring cell is determined as a candidate neighboring cell. Within the range of candidate neighboring cells, the terminal device determines the target reselection cell according to the absolute frequency priority cell reselection method.

[0139] Within the candidate neighbor cell range, the terminal device performs cell reselection according to the absolute frequency priority cell reselection method. If the neighbor cell meets the requirements, it is considered a suitable neighbor cell, and the neighbor cell is selected as the target reselection cell and camped on. If the neighbor cell does not meet the requirements, the next candidate neighbor cell is evaluated until a candidate neighbor cell meets the requirements.

[0140] If none of the candidate neighboring cells within the candidate neighboring cell range meet the requirements, then cell reselection is performed in all neighboring cells measured and acquired by the terminal device. Within the range of all neighboring cells of the terminal device, the terminal device determines the target reselection cell according to the absolute frequency priority cell reselection method and selects that neighboring cell for camping.

[0141] For example, such as Figure 4As shown, the terminal device determines the target model identifier set. The terminal device measures and obtains neighboring cell C and neighboring cell D. The model identifier set supported by neighboring cell C includes AI model identifier 3. The model identifier set supported by neighboring cell D of the terminal device includes AI model identifier 1 and AI model identifier 4. By comparison, the number of intersection elements between neighboring cell D and the target model identifier set meets the pre-set second threshold 2. Therefore, neighboring cell D is selected as a candidate neighboring cell. The absolute frequency priority cell reselection method is used to determine whether neighboring cell D can be used as the target reselection cell for camping.

[0142] Method 3: Select the first application model identifier with the highest priority in the target model identifier set, determine at least one neighboring cell that supports the first application model identifier as a candidate neighboring cell, and determine the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method.

[0143] For example, the first application model identifier with the highest priority is determined in the target model identifier set, and at least one neighboring cell that supports the first application model identifier is determined as a candidate neighboring cell in the neighboring cells of the terminal device. Within the candidate neighboring cells, the terminal device determines the target reselection cell according to the absolute frequency priority cell reselection method.

[0144] Within the candidate neighbor cell range, the terminal device performs cell reselection according to the absolute frequency priority cell reselection method. If the neighbor cell meets the requirements, it is considered a suitable neighbor cell, and the neighbor cell is selected as the target reselection cell and camped on. If the neighbor cell does not meet the requirements, the next candidate neighbor cell is evaluated until a candidate neighbor cell meets the requirements.

[0145] If none of the candidate neighboring cells within the candidate neighboring cell range meet the requirements, then cell reselection is performed in all neighboring cells of the terminal device. Within the range of all neighboring cells of the terminal device, the terminal device determines the target reselection cell according to the absolute frequency priority cell reselection method and selects that neighboring cell for camping.

[0146] For example, such as Figure 4As shown, the terminal device determines the target model identifier set, and the model identifier priority corresponding to the AI ​​model identifier is 1, which has the highest priority. The highest priority in the target model identifier set is AI model identifier 1. The terminal device measures and obtains neighboring cell C and neighboring cell D. Among the neighboring cells measured by the terminal device, neighboring cell D supports the highest priority AI model identifier 1. Therefore, neighboring cell D is selected as a candidate neighboring cell, and the absolute frequency priority cell reselection method is used to determine whether neighboring cell D can be used as the target reselection cell for camping. If neither neighboring cell C nor neighboring cell D supports the highest priority AI model identifier 1, the terminal device does not consider the model identifier priority and directly judges the measured neighboring cells according to the absolute frequency priority cell reselection method.

[0147] Method 4: Select the second application model identifier with the highest priority (i) in the target model identifier set, determine at least one neighboring cell that supports the second application model identifier as a candidate neighboring cell, and determine the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method; otherwise, if it is determined that none of the neighboring cells obtained by measurement support the second application model identifier, select the third application model identifier with the highest priority (i+1) in the target model identifier set, determine at least one neighboring cell that supports the third application model identifier as a candidate neighboring cell, and determine the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method; otherwise, repeat the previous step until a target reselection cell is determined, where the initial value of i is 1.

[0148] In one possible implementation, the terminal device selects the second application model identifier with the highest priority (i) from the target model identifier set, determines at least one neighboring cell that supports the second application model identifier as a candidate neighboring cell, and determines the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method. Otherwise, if it is determined that none of the measured neighboring cells support the second application model identifier, the terminal device selects the third application model identifier with the highest priority (i+1) from the target model identifier set, determines at least one neighboring cell that supports the third application model identifier as a candidate neighboring cell, and determines the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method. The initial value of i is 1. If none of the terminal device's neighboring cells support the second and third application model identifiers, the terminal device determines the target reselection cell from all the measured neighboring cells according to the absolute frequency priority cell reselection method.

[0149] In one possible implementation, the terminal device selects the second application model identifier with the highest priority in the target model identifier set, determines at least one neighboring cell that supports the second application model identifier as a candidate neighboring cell, and determines the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method; otherwise, if it is determined that none of the measured neighboring cells support the second application model identifier, the terminal device selects the third application model identifier with the highest priority in the target model identifier set, determines at least one neighboring cell that supports the third application model identifier as a candidate neighboring cell, and determines the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method; if it is determined that none of the neighboring cells support the third application model identifier, the terminal device selects the fourth application model identifier with the highest priority in the target model identifier set, and so on, selecting sequentially according to the priority order of the application model identifiers in the target model identifier set until a target reselection cell is determined.

[0150] Within the candidate neighbor cell range, if a cell meets the absolute frequency priority cell reselection method, then the neighbor cell is considered a suitable neighbor cell, and the neighbor cell is selected as the target reselection cell and camped on; if the neighbor cell does not meet the absolute frequency priority cell reselection method, then the next candidate neighbor cell is evaluated until a candidate neighbor cell meets the absolute frequency priority cell reselection method.

[0151] For example, such as Figure 4 As shown, the terminal device determines the target model identifier set, and the model identifier priority corresponding to AI model identifier 1 is 1. If the absolute frequency priority cell reselection method is not met in the neighboring cell D obtained by the terminal measurement, the second highest priority AI model identifier 2 is selected. According to the judgment, the neighboring cell D does not support the second highest priority AI model identifier 2, so the above steps are continued to select the third highest priority AI model identifier 3. The neighboring cell C supports the third highest priority AI model identifier 3, so the neighboring cell C is selected as a candidate neighboring cell, and the absolute frequency priority cell reselection method is used to determine whether the neighboring cell C can be used as the target reselection cell for camping.

[0152] If the terminal device's neighboring cells do not support the highest priority AI model identifier 1 or the second highest priority AI model identifier 2, then the previous step is executed again, and the third highest priority AI model identifier 3 is selected for judgment; if none of the terminal device's neighboring cells support any model identifier in the target model identifier set, then the terminal device does not consider the priority of the model identifier and directly judges the measured neighboring cells according to the absolute frequency priority cell reselection method.

[0153] In summary, the technical solution provided in this application involves a terminal device determining candidate neighboring cells based on the relationship between the identifier information of the application models supported by neighboring cells and the target model identifier set. Within the determined candidate neighboring cells, the terminal device then determines the target cell for reselection using an absolute frequency priority cell reselection method. This technical solution enables the terminal device to select neighboring cells that support the application models required by the terminal device, thereby obtaining more accurate cell reselection results and improving the user service experience.

[0154] Figure 6 A flowchart illustrating a cell selection method provided in an exemplary embodiment of this application is shown. This embodiment applies the method to a terminal device. The method includes:

[0155] Step 601: The terminal device determines the target model identifier set.

[0156] For example, the target model identifier set refers to the set of identifier information of the application model that the terminal device expects to obtain, and the target model identifier set contains the identifier information of at least one application model.

[0157] Optionally, the target model identifier set determined by the terminal device can be obtained through the terminal device's non-access layer (NAS), or the terminal device's access layer (AS), or through the network device configuration process; this application does not limit this.

[0158] Step 602: The terminal device selects a cell based on the model identifier information of the application model supported by the cell, the priority information of the application model, and the target model identifier set.

[0159] The model identification information of an application model refers to the identification information used to uniquely identify the application model.

[0160] For example, the terminal device makes a judgment based on the model identification information of the application model supported by the cell, the priority information of the application model, and the target model identification set. If the terminal device finds the target cell, it camps on the target cell.

[0161] The terminal device selects a cell based on the model identifier information of the application model supported by the cell, the priority information of the application model, and the target model identifier set, including at least one of the following two methods:

[0162] Method 1: Select the first application model identifier with the highest priority in the target model identifier set, determine at least one cell that supports the first application model identifier and whose application model priority information corresponding to the first application model identifier is relatively the highest as a candidate cell, and determine the target cell from the candidate cells according to the S criterion.

[0163] In one possible implementation, the terminal device selects the first application model identifier with the highest priority from the target model identifier set. If it is determined that none of the searched cells support the first application model identifier, the terminal device determines the target cell from the searched cells according to the S criterion.

[0164] In one possible implementation, the terminal device selects the first application model identifier with the highest priority in the target model identifier set, determines at least one cell that supports the first application model identifier, and selects at least one cell with the highest application model priority information corresponding to the first application model identifier among the at least one cell that supports the first application model identifier as a candidate cell. Within the candidate cell range, the terminal device determines the target cell according to the S criterion.

[0165] Within the candidate cell range, if a cell meets the S criterion, it is considered a suitable cell, selected as the target cell, and the cell is chosen for camping. If a cell does not meet the S criterion, the process continues to evaluate the next candidate cell until a candidate cell meets the S criterion.

[0166] If none of the candidate cells within the candidate cell range meet the S criterion, then the terminal device selects a cell from the cells it has searched. Within the cell range searched by the terminal device, the terminal device determines the target cell according to the S criterion and selects that cell to camp on.

[0167] For example, such as Figure 7 As shown, the terminal device determines the target model identifier set, where the model identifier priority corresponding to AI model identifier 1 is 1. If all cells searched by the terminal device support the highest priority AI model identifier 1, the device further determines the priority information of the AI ​​model corresponding to AI model identifier 1 in the cells that support it. Based on the comparison, cell B has the highest priority information for the AI ​​model corresponding to AI model identifier 1. Therefore, cell B is selected as a candidate cell, and the S criterion is used to determine whether cell B can be used as the target cell for camping.

[0168] Method 2: Select the second application model identifier with the highest priority in the target model identifier set, and determine at least one cell that supports the second application model identifier and has the highest application model priority information corresponding to the second application model identifier as a candidate cell. Determine the target cell from the candidate cells according to the S criterion. Otherwise, if it is determined that none of the searched cells support the second application model identifier, select the third application model identifier with the highest priority in the target model identifier set (i+1), and determine at least one cell that supports the third application model identifier and has the highest application model priority information corresponding to the third application model identifier as a candidate cell. Determine the target cell from the candidate cells according to the S criterion. Otherwise, repeat the previous step until a target cell is determined, where the initial value of i is 1.

[0169] In one possible implementation, the terminal device selects the second application model identifier with the highest priority (i) from the target model identifier set, identifies at least one cell that supports the second application model identifier and has the highest relative application model priority information as a candidate cell, and determines the target cell from the candidate cells according to the S criterion. Otherwise, if it is determined that none of the searched cells support the second application model identifier, the terminal device selects the third application model identifier with the highest priority (i+1) from the target model identifier set, identifies at least one cell that supports the third application model identifier and has the highest relative application model priority information as a candidate cell, and determines the target cell from the candidate cells according to the S criterion. If none of the cells searched by the terminal device support the second and third application model identifiers, the terminal device determines the target cell from all the searched cells according to the S criterion.

[0170] In one possible implementation, the terminal device selects the second application model identifier with the highest priority in the target model identifier set, determines at least one cell that supports the second application model identifier and has the highest application model priority information corresponding to the second application model identifier as a candidate cell, and determines the target cell from the candidate cells according to the S criterion; otherwise, if it is determined that none of the searched cells support the second application model identifier, the terminal device selects the third application model identifier with the highest priority in the target model identifier set, determines at least one cell that supports the third application model identifier and has the highest application model priority information corresponding to the third application model identifier as a candidate cell, and determines the target cell from the candidate cells according to the S criterion; otherwise, if it is determined that none of the searched cells support the third application model identifier, the terminal device selects the fourth application model identifier with the highest priority in the target model identifier set, and so on, selecting sequentially according to the priority order of the application model identifiers in the target model identifier set until a target cell is determined.

[0171] Within the candidate cell range, if a cell meets the S criterion, it is considered a suitable cell, selected as the target cell, and the cell is chosen for camping. If a cell does not meet the S criterion, the process continues to evaluate the next candidate cell until a candidate cell meets the S criterion.

[0172] In one possible implementation, if none of the cells searched by the terminal device support any of the application model identifiers included in the target model identifier set, the terminal device determines the target cell from all the cells searched according to the S criterion.

[0173] For example, such as Figure 7 As shown, the terminal device determines the target model identifier set, and the model identifier priority corresponding to AI model identifier 1 is 1. If cell A searched by the terminal device does not meet the S criterion, the second highest priority AI model identifier 2 is selected. According to the judgment, both cell A and cell B support the second highest priority AI model identifier 2, but the priority information of the AI ​​model corresponding to AI model identifier 2 in cell A is relatively the highest. Therefore, cell A is selected as a candidate cell, and the S criterion is used to determine whether cell A can be used as the target cell for camping.

[0174] If the cell searched by the terminal device does not support the highest priority AI model identifier 1 or the second highest priority AI model identifier 2, then the previous step is executed again, and the third highest priority AI model identifier 3 is selected for further judgment; if none of the cells searched by the terminal device support any model identifier in the target model identifier set, then the terminal device does not consider the priority of the model identifier and the priority information of the application model, and directly judges the searched cells according to the S criterion.

[0175] In summary, the technical solution provided in this application embodiment involves a terminal device determining candidate cells based on the relationship between the model identifier information of the application models supported by the searched cells, the priority information of the application models, and the target model identifier set. Within the determined candidate cell range, the terminal device then determines the target cell according to the S criterion. This technical solution enables the terminal device to select cells that support the application models required by the terminal device, thereby obtaining more accurate cell selection results and improving the user service experience.

[0176] Figure 8 A flowchart illustrating a cell selection method provided in an exemplary embodiment of this application is shown. This embodiment applies the method to a terminal device. The method includes:

[0177] Step 801: The terminal device determines the target model identifier set.

[0178] For example, the target model identifier set refers to the set of identifier information of the application model that the terminal device expects to obtain, and the target model identifier set contains the identifier information of at least one application model.

[0179] Optionally, the target model identifier set determined by the terminal device can be obtained through the terminal device's non-access layer (NAS), or the terminal device's access layer (AS), or through the network device configuration process; this application does not limit this.

[0180] Step 802: The terminal device selects a cell based on the model identifier information of the application model supported by the cell, the accuracy level information of the application model, and the target model identifier set.

[0181] The model identification information of an application model refers to the identification information used to uniquely identify the application model.

[0182] For example, the terminal device makes a judgment based on the model identification information of the application model supported by the cell, the accuracy level information of the application model, and the target model identification set. If the terminal device finds the target cell, it camps on the target cell.

[0183] The terminal device selects a cell based on the model identifier information of the application model supported by the cell, the accuracy level information of the application model, and the target model identifier set, including at least one of the following two methods:

[0184] Method 1: Select the first application model identifier with the highest priority in the target model identifier set, determine at least one cell that supports the first application model identifier and whose application model accuracy level information corresponding to the first application model identifier is relatively the highest as a candidate cell, and determine the target cell from the candidate cells according to the S criterion.

[0185] In one possible implementation, the terminal device selects the first application model identifier with the highest priority from the target model identifier set. If it is determined that none of the searched cells support the first application model identifier, the terminal device determines the target cell from the searched cells according to the S criterion.

[0186] In one possible implementation, the terminal device selects the first application model identifier with the highest priority in the target model identifier set, determines at least one cell that supports the first application model identifier, and selects at least one cell with the highest relative application model accuracy level information corresponding to the first application model identifier among the at least one cell that supports the first application model identifier as a candidate cell. Within the candidate cell range, the terminal device determines the target cell according to the S criterion.

[0187] Within the candidate cell range, if a cell meets the S criterion, it is considered a suitable cell, selected as the target cell, and the cell is chosen for camping. If a cell does not meet the S criterion, the process continues to evaluate the next candidate cell until a candidate cell meets the S criterion.

[0188] If none of the candidate cells within the candidate cell range meet the S criterion, then the terminal device selects a cell from the cells it has searched. Within the cell range searched by the terminal device, the terminal device determines the target cell according to the S criterion and selects that cell to camp on.

[0189] For example, such as Figure 7 As shown, the terminal device determines the target model identifier set, where the model identifier priority corresponding to AI model identifier 1 is 1. If both cell A and cell B searched by the terminal device support the highest priority AI model identifier 1, the device further determines the accuracy level information of the AI ​​model corresponding to AI model identifier 1 in the cell supporting the highest priority AI model identifier. Based on the comparison, the accuracy level information of the AI ​​model corresponding to AI model identifier 1 in cell A is relatively the highest. Therefore, cell A is selected as a candidate cell, and the S criterion is used to determine whether cell A can be used as the target cell for camping.

[0190] Method 2: Select the second application model identifier with the highest priority in the target model identifier set, and determine at least one cell that supports the second application model identifier and has the highest relative application model accuracy level information as a candidate cell. Determine the target cell from the candidate cells according to the S criterion. Otherwise, if it is determined that none of the searched cells support the second application model identifier, select the third application model identifier with the highest priority in the target model identifier set (i+1), and determine at least one cell that supports the third application model identifier and has the highest relative application model accuracy level information as a candidate cell. Determine the target cell from the candidate cells according to the S criterion. Otherwise, repeat the previous step until a target cell is determined, where the initial value of i is 1.

[0191] In one possible implementation, the terminal device selects the second application model identifier with the highest priority (i) from the target model identifier set, identifies at least one cell that supports the second application model identifier and has the highest relative application model accuracy level information as a candidate cell, and determines the target cell from the candidate cells according to the S criterion. Otherwise, if it is determined that none of the searched cells support the second application model identifier, the terminal device selects the third application model identifier with the highest priority (i+1) from the target model identifier set, identifies at least one cell that supports the third application model identifier and has the highest relative application model accuracy level information as a candidate cell, and determines the target cell from the candidate cells according to the S criterion. If none of the cells searched by the terminal device support the second and third application model identifiers, the terminal device determines the target cell from all the searched cells according to the S criterion.

[0192] In one possible implementation, the terminal device selects the second application model identifier with the highest priority in the target model identifier set, determines at least one cell that supports the second application model identifier and has the highest relative application model accuracy level information corresponding to the second application model identifier as a candidate cell, and determines the target cell from the candidate cells according to the S criterion; otherwise, if it is determined that none of the searched cells support the second application model identifier, the terminal device selects the third application model identifier with the highest priority in the target model identifier set, determines at least one cell that supports the third application model identifier and has the highest relative application model accuracy level information corresponding to the third application model identifier as a candidate cell, and determines the target cell from the candidate cells according to the S criterion; otherwise, if it is determined that none of the searched cells support the third application model identifier, the terminal device selects the fourth application model identifier with the highest priority in the target model identifier set, and so on, selecting sequentially according to the priority order of the application model identifiers in the target model identifier set until a target cell is determined.

[0193] Within the candidate cell range, if a cell meets the S criterion, it is considered a suitable cell, selected as the target cell, and the cell is chosen for camping. If a cell does not meet the S criterion, the process continues to evaluate the next candidate cell until a candidate cell meets the S criterion.

[0194] In one possible implementation, if none of the cells searched by the terminal device support any of the application model identifiers included in the target model identifier set, the terminal device determines the target cell from all the cells searched according to the S criterion.

[0195] For example, if none of the candidate cells within the candidate cell range meet the S criterion, then cell selection is performed among the cells searched by the terminal device. Within the cell range searched by the terminal device, the terminal device determines the target cell according to the S criterion and selects that cell to camp on.

[0196] For example, such as Figure 7 As shown, the terminal device determines the target model identifier set, and the model identifier priority corresponding to AI model identifier 1 is 1. If neither cell A nor cell B searched by the terminal device supports the highest priority AI model identifier 1, the second highest priority AI model identifier 2 is selected. Based on the judgment, both cell A and cell B support the second highest priority AI model identifier 2, and the AI ​​model accuracy level information corresponding to AI model identifier 2 in cell B is relatively the highest. Therefore, cell B is selected as a candidate cell, and the S criterion is used to determine whether cell B can be used as the target cell for stationing.

[0197] If the cell searched by the terminal device does not support the highest priority AI model identifier 1 or the second highest priority AI model identifier 2, then the previous step is executed again, and the third highest priority AI model identifier 3 is selected for further judgment; if none of the cells searched by the terminal device support any model identifier in the target model identifier set, then the terminal device does not consider the priority of the model identifier and the accuracy level information of the applied model, and directly judges the searched cells according to the S criterion.

[0198] In summary, the technical solution provided in this application embodiment involves a terminal device determining candidate cells based on the relationship between the model identifier information of the application models supported by the searched cells, the accuracy level information of the application models, and the target model identifier set. Based on the determined candidate cells, within the candidate cell range, the terminal device determines the target cell according to the S criterion. The technical solution provided in this application embodiment enables the terminal device to select cells that support the application models required by the terminal device, thereby obtaining more accurate cell selection results and improving the user service experience.

[0199] Figure 9 A flowchart illustrating a cell selection method provided in an exemplary embodiment of this application is shown. This embodiment applies the method to a terminal device. The method includes:

[0200] Step 901: The terminal device determines the target model identifier set.

[0201] For example, the target model identifier set refers to the set of identifier information of the application model that the terminal device expects to obtain, and the target model identifier set contains the identifier information of at least one application model.

[0202] Optionally, the target model identifier set determined by the terminal device can be obtained through the terminal device's non-access layer (NAS), or the terminal device's access layer (AS), or through the network device configuration process; this application does not limit this.

[0203] Step 902: The terminal device selects a cell based on the model identifier information of the application model supported by the cell, the priority information of the application model, the accuracy level information of the application model, and the target model identifier set.

[0204] For example, the terminal device makes a judgment based on the model identifier information of the application model supported by the cell, the priority information of the application model, the accuracy level information of the application model, and the target model identifier set. If the terminal device finds the target cell, it camps on the target cell.

[0205] The terminal device selects a cell based on the model identifier information of the application model supported by the cell, the priority information of the application model, the accuracy level information of the application model, and the target model identifier set, including at least one of the following two methods:

[0206] Method 1: Select the first application model identifier with the highest priority in the target model identifier set, determine at least one cell that supports the first application model identifier and whose application model priority information and application model accuracy level information corresponding to the first application model identifier are relatively the highest as candidate cells, and determine the target cell from the candidate cells according to the S criterion.

[0207] In one possible implementation, the terminal device selects the first application model identifier with the highest priority from the target model identifier set. If it is determined that none of the searched cells support the first application model identifier, the terminal device determines the target cell from the searched cells according to the S criterion.

[0208] In one possible implementation, the terminal device selects the first application model identifier with the highest priority in the target model identifier set, determines at least one cell that supports the first application model identifier, and selects at least one cell among the at least one cell that supports the first application model identifier as the candidate cell with the highest relative priority information and application model accuracy level information of the application model corresponding to the first application model identifier. Within the candidate cell range, the terminal device determines the target cell according to the S criterion.

[0209] Within the candidate cell range, if a cell meets the S criterion, it is considered a suitable cell, selected as the target cell, and the cell is chosen for camping. If a cell does not meet the S criterion, the process continues to evaluate the next candidate cell until a candidate cell meets the S criterion.

[0210] If none of the candidate cells within the candidate cell range meet the S criterion, then the terminal device selects a cell from the cells it has searched. Within the cell range searched by the terminal device, the terminal device determines the target cell according to the S criterion and selects that cell to camp on.

[0211] Optionally, selecting at least one cell with the highest relative priority information and accuracy level information of the application model corresponding to the application model identifier as a candidate cell means, when the application model has priority information and accuracy level information, selecting at least one cell with the highest relative priority information and accuracy level information of the application model as a candidate cell; or, selecting at least one cell with equal priority information but the highest relative accuracy level information of the application model as a candidate cell; or, selecting at least one cell with the highest relative priority information and equal accuracy level information of the application model as a candidate cell; or, selecting at least one cell with the highest sum of priority information and accuracy level information of the application model as a candidate cell. This application does not limit this.

[0212] For example, such as Figure 7 As shown, the terminal device determines the target model identifier set, and the model identifier priority corresponding to AI model identifier 1 is 1. If both cell A and cell B searched by the terminal device support the highest priority AI model identifier 1, the device further determines the priority and accuracy level information of the AI ​​model corresponding to AI model identifier 1 in the cells supporting the highest priority AI model identifier 1. The priority information of AI model 1 in cell A is 2, which is one level lower than the priority information of AI model 1 in cell B. The accuracy level information of AI model 1 in cell A is 1, which is two levels higher than the accuracy level information of AI model 1 in cell B. Therefore, cell A is selected as a candidate cell, and the S criterion is used to determine whether cell A can be used as the target cell for camping.

[0213] Method 2: Select the second application model identifier with the highest priority (i) in the target model identifier set. Determine at least one cell that supports the second application model identifier and whose application model priority information and application model accuracy level information are relatively the highest as a candidate cell. Determine the target cell from the candidate cells according to the S criterion. Otherwise, if it is determined that none of the searched cells support the second application model identifier, select the third application model identifier with the highest priority (i+1) in the target model identifier set. Determine at least one cell that supports the third application model identifier and whose application model priority information and application model accuracy level information are relatively the highest as a candidate cell. Determine the target cell from the candidate cells according to the S criterion. Otherwise, repeat the previous step until a target cell is determined, where the initial value of i is 1.

[0214] In one possible implementation, the terminal device selects the second application model identifier with the highest priority (i) from the target model identifier set, and determines at least one cell that supports the second application model identifier and whose application model priority information and application model accuracy level information corresponding to the second application model identifier are relatively the highest as candidate cells. The target cell is then determined from the candidate cells according to the S criterion. Otherwise, if it is determined that none of the searched cells support the second application model identifier, the terminal device selects the third application model identifier with the highest priority (i+1) from the target model identifier set, and determines at least one cell that supports the third application model identifier and whose application model priority information and application model accuracy level information corresponding to the third application model identifier are relatively the highest as candidate cells. The target cell is then determined from the candidate cells according to the S criterion. If none of the cells searched by the terminal device support the second and third application model identifiers, the terminal device determines the target cell from all the searched cells according to the S criterion.

[0215] In one possible implementation, the terminal device selects the second application model identifier with the highest priority in the target model identifier set, and determines at least one cell that supports the second application model identifier and whose application model priority information and application model accuracy level information corresponding to the second application model identifier are relatively the highest as candidate cells. The target cell is then determined from the candidate cells according to the S criterion. Otherwise, if it is determined that none of the searched cells support the second application model identifier, the terminal device selects the third application model identifier with the highest priority in the target model identifier set, and determines at least one cell that supports the third application model identifier and whose application model priority information and application model accuracy level information corresponding to the third application model identifier are relatively the highest as candidate cells. The target cell is then determined from the candidate cells according to the S criterion. Otherwise, if it is determined that none of the searched cells support the third application model identifier, the terminal device selects the fourth application model identifier with the highest priority in the target model identifier set, and so on, selecting sequentially according to the priority order of the application model identifiers in the target model identifier set until a target cell is determined.

[0216] Within the candidate cell range, if a cell meets the S criterion, it is considered a suitable cell, selected as the target cell, and the cell is chosen for camping. If a cell does not meet the S criterion, the process continues to evaluate the next candidate cell until a candidate cell meets the S criterion.

[0217] In one possible implementation, if none of the cells searched by the terminal device support any of the application model identifiers included in the target model identifier set, the terminal device determines the target cell from all the cells searched according to the S criterion.

[0218] For example, if none of the candidate cells within the candidate cell range meet the S criterion, then cell selection is performed among the cells searched by the terminal device. Within the cell range searched by the terminal device, the terminal device determines the target cell according to the S criterion and selects that cell to camp on.

[0219] For example, such as Figure 7 As shown, the terminal device determines the target model identifier set, and the model identifier priority corresponding to AI model identifier 1 is 1. If neither cell A nor cell B searched by the terminal device supports the highest priority AI model identifier 1, then the second highest priority AI model identifier 2 is selected. Both cell A and cell B support the second highest priority AI model identifier 2. Further analysis is conducted on the priority and accuracy level information of the AI ​​model corresponding to AI model identifier 2. The accuracy level information of the AI ​​model corresponding to AI model identifier 2 in cell A is one level lower than that in cell B, and the priority information of the AI ​​model corresponding to AI model identifier 2 in cell A is one level higher than that in cell B. Therefore, cell A and cell B are selected as candidate cells, and the S criterion is used to determine whether cell A and cell B can be used as target cells for stationing.

[0220] If the cells searched by the terminal device do not support the highest priority AI model identifier 1 or the second highest priority AI model identifier 2, then the previous step is executed again, and the third highest priority AI model identifier 3 is selected for further judgment; if none of the cells searched by the terminal device support any model identifier in the target model identifier set, then the terminal device does not consider the priority of the model identifier, the priority information of the application model, and the accuracy level information of the application model, and directly judges the searched cells according to the S criterion.

[0221] In summary, the technical solution provided in this application embodiment allows the terminal device to determine candidate cells based on the relationship between the model identifier information, priority information, accuracy level information, and target model identifier set of the application models supported by the searched cells. Within the candidate cell range, the terminal device then determines the target cell according to the S criterion. This technical solution enables the terminal device to select cells that support the application models required by the terminal device, thereby obtaining more accurate cell selection results and improving the user service experience.

[0222] Figure 10 A flowchart illustrating a cell reselection method provided in an exemplary embodiment of this application is shown. This embodiment applies the method to a terminal device. The method includes:

[0223] Step 1001: The terminal device determines the target model identifier set.

[0224] For example, the target model identifier set refers to the set of identifier information of the application model that the terminal device expects to obtain, and the target model identifier set contains the identifier information of at least one application model.

[0225] Optionally, the target model identifier set determined by the terminal device can be obtained through the NAS of the terminal device, or the AS of the terminal device, or through the network device configuration process, and this application does not limit this.

[0226] Step 1002: The terminal device performs cell reselection based on the model identifier information of the application model supported by the cell, the priority information of the application model, and the target model identifier set.

[0227] The terminal device performs cell reselection based on the identification information of the application models supported by the serving cell and / or at least one neighboring cell, the priority information of the application models supported by the serving cell and / or at least one neighboring cell, and the target model identification set.

[0228] The terminal device performs cell reselection based on the model identifier information of the application model supported by the cell, the priority information of the application model, and the target model identifier set, including at least one of the following four methods:

[0229] Method 1: Select the first application model identifier with the highest priority in the target model identifier set, determine at least one neighboring cell that supports the first application model identifier and has the highest relative application model priority information corresponding to the first application model identifier as a candidate neighboring cell, and determine the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method.

[0230] In one possible implementation, the terminal device selects the first application model identifier with the highest priority from the target model identifier set. If it is determined that none of the neighboring cells acquired by measurement support the first application model identifier, the terminal device determines the target reselection cell from the neighboring cells acquired by measurement according to the absolute frequency priority cell reselection method.

[0231] In one possible implementation, the terminal device selects the first application model identifier with the highest priority in the target model identifier set, determines at least one neighboring cell that supports the first application model identifier, and selects at least one neighboring cell with the highest application model priority information corresponding to the first application model identifier among the at least one neighboring cell that supports the first application model identifier as a candidate neighboring cell. Within the candidate neighboring cell range, the terminal device determines the target reselection cell according to the absolute frequency priority cell reselection method.

[0232] Within the candidate neighbor cell range, if a neighbor cell meets the absolute frequency priority cell reselection method, it is considered a suitable neighbor cell, and is selected as the target reselection cell for camping. If a neighbor cell does not meet the absolute frequency priority cell reselection method, the next candidate neighbor cell is evaluated until a candidate neighbor cell meets the absolute frequency priority cell reselection method.

[0233] If none of the candidate neighboring cells within the candidate neighboring cell range meet the absolute frequency priority cell reselection method, then cell reselection is performed in the neighboring cells measured and obtained by the terminal device. Within the range of neighboring cells measured and obtained by the terminal device, the terminal device determines the target reselection cell according to the absolute frequency priority cell reselection method and selects that neighboring cell for camping.

[0234] For example, such as Figure 7 As shown, the terminal device determines the target model identifier set, and the model identifier priority corresponding to AI model identifier 1 is 1. When neighboring cells C and D, as measured by the terminal device, both support the highest-priority AI model identifier, the priority information of the AI ​​model corresponding to AI model identifier 1 is further determined among the neighboring cells supporting the highest-priority AI model identifier 1. Based on the comparison, the priority information of the AI ​​model corresponding to AI model identifier 1 in neighboring cell C is relatively the highest. Therefore, neighboring cell C is selected as a candidate neighboring cell, and the absolute frequency priority cell reselection method is used to determine whether neighboring cell C can be used as the target reselection cell for camping.

[0235] Method 2: Select the second application model identifier with the highest priority (i) in the target model identifier set. Determine at least one neighboring cell that supports the second application model identifier and has the highest relative application model priority information as a candidate neighboring cell. Determine the target reselection cell from the candidate neighboring cells using the absolute frequency priority cell reselection method. Otherwise, if it is determined that none of the neighboring cells obtained by measurement support the second application model identifier, select the third application model identifier with the highest priority (i+1) in the target model identifier set. Determine at least one neighboring cell that supports the third application model identifier and has the highest relative application model priority information as a candidate neighboring cell. Determine the target reselection cell from the candidate neighboring cells using the absolute frequency priority cell reselection method. Otherwise, repeat the previous step until a target reselection cell is determined, where the initial value of i is 1.

[0236] In one possible implementation, the terminal device selects the second application model identifier with the highest priority (i) from the target model identifier set, determines at least one neighboring cell that supports the second application model identifier and has the highest relative application model priority information corresponding to the second application model identifier as a candidate neighboring cell, and determines the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method; otherwise, if it is determined that none of the measured neighboring cells support the second application model identifier, the terminal device selects the third application model identifier with the highest priority (i+1) from the target model identifier set, determines at least one neighboring cell that supports the third application model identifier and has the highest relative application model priority information corresponding to the third application model identifier as a candidate neighboring cell, and determines the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method. If none of the measured neighboring cells support the second and third application model identifiers, the terminal device determines the target reselection cell from all the measured cells according to the frequency priority cell reselection method.

[0237] In one possible implementation, the terminal device selects the second application model identifier with the highest priority in the target model identifier set, determines at least one neighboring cell that supports the second application model identifier and has the highest relative application model priority information corresponding to the second application model identifier as a candidate neighboring cell, and determines the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method; otherwise, if it is determined that none of the measured neighboring cells support the second application model identifier, the terminal device selects the third application model identifier with the highest priority in the target model identifier set, determines at least one neighboring cell that supports the third application model identifier and has the highest relative application model priority information corresponding to the third application model identifier as a candidate neighboring cell, and determines the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method; otherwise, if it is determined that none of the measured neighboring cells support the third application model identifier, the terminal device selects the fourth application model identifier with the highest priority in the target model identifier set, and so on, performing reselection sequentially according to the priority order of the application model identifiers in the target model identifier set until a target reselection cell is determined.

[0238] Within the candidate neighbor cell range, if a neighbor cell meets the absolute frequency priority cell reselection method, it is considered a suitable neighbor cell, and is selected as the target reselection cell for camping. If a neighbor cell does not meet the absolute frequency priority cell reselection method, the next candidate neighbor cell is evaluated until a candidate neighbor cell meets the absolute frequency priority cell reselection method.

[0239] In one possible implementation, if none of the neighboring cells measured by the terminal device support any of the application model identifiers included in the target model identifier set, the terminal device determines the target reselection cell from all the neighboring cells measured using the absolute frequency priority cell reselection method.

[0240] For example, if none of the candidate neighboring cells within the candidate neighboring cell range meet the absolute frequency priority cell reselection method, then cell reselection is performed in the neighboring cells measured and obtained by the terminal device. Within the range of neighboring cells measured and obtained by the terminal device, the terminal device determines the target reselection cell according to the absolute frequency priority cell reselection method and selects that neighboring cell for camping.

[0241] For example, such as Figure 7 As shown, the terminal device determines the target model identifier set, and the model identifier priority corresponding to AI model identifier 1 is 1. If neither neighboring cell C nor neighboring cell D, as measured by the terminal device, supports the highest priority AI model identifier 1, the second highest priority AI model identifier 2 is selected. Based on the judgment, neighboring cell D supports the second highest priority AI model identifier 2, and the AI ​​model priority information corresponding to AI model identifier 2 is relatively the highest. Therefore, neighboring cell D is selected as a candidate neighboring cell, and the absolute frequency priority cell reselection method is used to determine whether neighboring cell D can be used as the target reselection cell for camping.

[0242] Method 3: Select the first application model identifier with the highest priority in the target model identifier set, determine at least one neighboring cell that supports the first application model identifier, and in the at least one neighboring cell that supports the first application model identifier, use the priority information of the application model corresponding to the first application model identifier as the new frequency priority of the corresponding neighboring cell, determine the neighboring cell with the new frequency priority as the candidate neighboring cell, and determine the target reselection cell in the candidate neighboring cells according to the absolute frequency priority cell reselection method.

[0243] In one possible implementation, the terminal device selects the first application model identifier with the highest priority from the target model identifier set. If it is determined that none of the neighboring cells acquired by measurement support the first application model identifier, the terminal device determines the target reselection cell from the neighboring cells acquired by measurement according to the absolute frequency priority cell reselection method.

[0244] For example, the terminal device determines the first application model identifier with the highest priority from the target model identifier set determined by the terminal device, determines at least one neighboring cell that supports the first application model identifier from the neighboring cells measured and acquired by the terminal device, uses the priority information of the application model corresponding to the first application model identifier as the new frequency priority of the corresponding neighboring cell from the at least one neighboring cell that supports the first application model identifier, uses the new frequency priority of the neighboring cell as the new frequency priority of the neighboring cell, uses the neighboring cell with the new frequency priority as the candidate neighboring cell, and determines the target reselection cell from the candidate neighboring cell range according to the absolute frequency priority cell reselection method.

[0245] Within the candidate neighbor cell range, if a neighbor cell meets the absolute frequency priority cell reselection method, it is considered a suitable neighbor cell, and is selected as the target reselection cell for camping. If a neighbor cell does not meet the absolute frequency priority cell reselection method, the next candidate neighbor cell is evaluated until a candidate neighbor cell meets the absolute frequency priority cell reselection method.

[0246] In one possible implementation, the first application model identifier with the highest priority in the target model identifier set is selected. If it is determined that none of the neighboring cells obtained by measurement support the first application model identifier, the terminal device determines the target reselection cell from the neighboring cells obtained by measurement according to the absolute frequency priority cell reselection method.

[0247] For example, if none of the candidate neighboring cells within the candidate neighboring cell range meet the absolute frequency priority cell reselection method, then cell reselection is performed in the neighboring cells measured and obtained by the terminal device. Within the range of neighboring cells measured and obtained by the terminal device, the terminal device determines the target reselection cell according to the absolute frequency priority cell reselection method and selects that neighboring cell for camping.

[0248] For example, such as Figure 11 As shown, the terminal device determines the target model identifier set, and the model identifier priority corresponding to AI model identifier 1 is 1. AI model identifier 1 has the highest priority in the target model identifier set. Among the neighboring cells C and D measured by the terminal device, neighboring cell D supports the highest priority AI model identifier 1. In neighboring cell D that supports AI model identifier 1, the model priority information of the AI ​​model is used as the new frequency priority of neighboring cell D. The frequency priority of neighboring cell D changes from 5 to 3, so neighboring cell D is selected as a candidate neighboring cell. The absolute frequency priority cell reselection method is used to determine whether neighboring cell D can be used as the target reselection cell for camping. If neither neighboring cell C nor neighboring cell D measured by the terminal device supports the highest priority AI model identifier 1, the terminal device does not consider the model identifier priority and directly performs reselection on the measured neighboring cells according to the absolute frequency priority cell reselection method.

[0249] Method 4: Select the second application model identifier with the highest priority (i) in the target model identifier set, determine at least one neighboring cell that supports the second application model identifier, and among the at least one neighboring cell that supports the second application model identifier, use the priority information of the application model corresponding to the second application model identifier as the new frequency priority of the corresponding neighboring cell, determine the neighboring cell with the new frequency priority as the candidate neighboring cell, and determine the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method; otherwise, if it is determined that none of the neighboring cells obtained by measurement support the second application model identifier, select the third application model identifier with the highest priority (i+1) in the target model identifier set, determine at least one neighboring cell that supports the third application model identifier, and among the at least one neighboring cell that supports the third application model identifier, use the priority information of the application model corresponding to the third application model identifier as the new frequency priority of the corresponding neighboring cell, determine the neighboring cell with the new frequency priority as the candidate neighboring cell, and determine the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method; otherwise, repeat the previous step until a target reselection cell is determined, where the initial value of i is 1.

[0250] In one possible implementation, the terminal device selects the second application model identifier with the highest priority in the target model identifier set, determines at least one neighboring cell that supports the second application model identifier, and among the at least one neighboring cell that supports the second application model identifier, uses the priority information of the application model corresponding to the second application model identifier as the new frequency priority of the corresponding neighboring cell, determines the neighboring cell with the new frequency priority as a candidate neighboring cell, and determines the target reselection cell among the candidate neighboring cells according to the absolute frequency priority cell reselection method; otherwise, if it is determined that none of the neighboring cells obtained by measurement support the second application model identifier, the terminal device selects the third application model identifier with the highest priority in the target model identifier set (i+1), determines at least one neighboring cell that supports the third application model identifier, and among the at least one neighboring cell that supports the third application model identifier, uses the priority information of the application model corresponding to the third application model identifier as the new frequency priority of the corresponding neighboring cell, determines the neighboring cell with the new frequency priority as a candidate neighboring cell, and determines the target reselection cell among the candidate neighboring cells according to the absolute frequency priority cell reselection method. If none of the neighboring cells measured by the terminal device support the second application model identifier and the third application model identifier, the terminal device determines the target cell for reselection from all the cells measured based on the frequency point priority cell reselection method.

[0251] In one possible implementation, the terminal device selects the second application model identifier with the highest priority (i) from the target model identifier set, determines at least one neighboring cell that supports the second application model identifier, and among the at least one neighboring cell that supports the second application model identifier, uses the priority information of the application model corresponding to the second application model identifier as the new frequency priority of the corresponding neighboring cell, determines the neighboring cell with the new frequency priority as a candidate neighboring cell, and determines the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method; otherwise, if it is determined that none of the neighboring cells obtained by measurement support the second application model identifier, the terminal device selects the third application model identifier with the highest priority (i+1) from the target model identifier set, and determines the cell that supports the third application model identifier. For at least one neighboring cell with an application model identifier, among at least one neighboring cell that supports a third application model identifier, the priority information of the application model corresponding to the third application model identifier is used as the new frequency priority of the corresponding neighboring cell. The neighboring cell with the new frequency priority is determined as a candidate neighboring cell. The target reselection cell is determined from the candidate neighboring cells according to the absolute frequency priority cell reselection method. Otherwise, if it is determined that none of the neighboring cells obtained by measurement support the third application model identifier, the fourth application model identifier with the (i+2)th highest priority in the target model identifier set is selected. This process is repeated, and the selection is carried out sequentially according to the priority order of the application model identifiers in the target model identifier set until a target reselection cell is determined. The initial value of i is 1.

[0252] Within the candidate neighbor cell range, if a neighbor cell meets the absolute frequency priority cell reselection method, it is considered a suitable neighbor cell, and is selected as the target reselection cell for camping. If a neighbor cell does not meet the absolute frequency priority cell reselection method, the next candidate neighbor cell is evaluated until a candidate neighbor cell meets the absolute frequency priority cell reselection method.

[0253] In one possible implementation, if none of the neighboring cells measured by the terminal device support any of the application model identifiers included in the target model identifier set, the terminal device determines the target reselection cell from all the neighboring cells measured using the absolute frequency priority cell reselection method.

[0254] For example, if none of the candidate neighboring cells within the candidate neighboring cell range meet the absolute frequency priority cell reselection method, then cell reselection is performed in the neighboring cells measured and obtained by the terminal device. Within the range of neighboring cells measured and obtained by the terminal device, the terminal device determines the target reselection cell according to the absolute frequency priority cell reselection method and selects that neighboring cell for camping.

[0255] For example, such as Figure 12As shown, the terminal device determines that the target model identifier set includes AI model identifier 1, AI model identifier 2, AI model identifier 3, and AI model identifier 4, where the model identifier priority corresponding to AI model identifier 1 is 1. If neither the neighboring cell C nor the neighboring cell D measured by the terminal device supports the highest priority AI model identifier 1, then the second highest priority AI model identifier 2 is selected. Based on the judgment, neighboring cell D supports the second highest priority AI model identifier 2. In neighboring cell D that supports AI model identifier 2, the model priority information of AI model identifier 2 is used as the new frequency priority of neighboring cell D. The frequency priority of neighboring cell D changes from 5 to 1. Therefore, neighboring cell D is selected as a candidate neighboring cell, and the absolute frequency priority cell reselection method is used to determine whether neighboring cell D can be used as the target reselection cell for camping.

[0256] If the neighboring cells measured by the terminal device do not support the highest priority AI model identifier 1 or the second highest priority AI model identifier 2, then the previous step is executed again, and the third highest priority AI model identifier 3 is selected for judgment; if none of the neighboring cells measured by the terminal device support any model identifier in the target model identifier set, then the terminal device does not consider the priority of the model identifier and directly judges the measured neighboring cells according to the absolute frequency priority cell reselection method.

[0257] In summary, the technical solution provided in this application involves a terminal device determining candidate neighboring cells based on the relationship between the model identifier information of the application models supported by neighboring cells, the priority information of the application models, and the target model identifier set obtained through measurement. Within the determined candidate neighboring cells, the terminal device then determines the target reselection cell using an absolute frequency priority cell reselection method. This technical solution enables the terminal device to select cells that support the application models required by the terminal device, thereby obtaining more accurate cell reselection results and improving the user service experience.

[0258] Figure 13 A flowchart illustrating a cell reselection method provided in an exemplary embodiment of this application is shown. This embodiment applies the method to a terminal device. The method includes:

[0259] Step 1301: The terminal device determines the target model identifier set.

[0260] For example, the target model identifier set refers to the set of identifier information of the application model that the terminal device expects to obtain, and the target model identifier set contains the identifier information of at least one application model.

[0261] Optionally, the target model identifier set determined by the terminal device can be obtained through the NAS of the terminal device, or the AS of the terminal device, or through the network device configuration process, and this application does not limit this.

[0262] Step 1302: The terminal device performs cell reselection based on the model identifier information of the application model supported by the cell, the accuracy level information of the application model, and the target model identifier set.

[0263] The terminal device performs cell reselection based on the identification information of the application model supported by the serving cell and / or at least one neighboring cell, the accuracy level information of the application model supported by the serving cell and / or at least one neighboring cell, and the target model identification set.

[0264] The terminal device performs cell reselection based on the model identifier information of the application model supported by the cell, the accuracy level information of the application model, and the target model identifier set, including at least one of the following two methods:

[0265] Method 1: Select the first application model identifier with the highest priority in the target model identifier set, determine at least one neighboring cell that supports the first application model identifier and has the highest relative application model accuracy level information corresponding to the first application model identifier as a candidate neighboring cell, and determine the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method.

[0266] In one possible implementation, the terminal device selects the first application model identifier with the highest priority from the target model identifier set. If it is determined that none of the neighboring cells acquired by measurement support the first application model identifier, the terminal device determines the target reselection cell from the neighboring cells acquired by measurement according to the absolute frequency priority cell reselection method.

[0267] In one possible implementation, the terminal device selects the first application model identifier with the highest priority in the target model identifier set, determines at least one neighboring cell that supports the first application model identifier, and selects at least one neighboring cell with the highest relative application model accuracy level information corresponding to the first application model identifier among the at least one neighboring cell that supports the first application model identifier as a candidate neighboring cell. Within the candidate neighboring cell range, the terminal device determines the target reselection cell according to the absolute frequency priority cell reselection method.

[0268] Within the candidate neighbor cell range, if a neighbor cell meets the absolute frequency priority cell reselection method, it is considered a suitable neighbor cell, and is selected as the target reselection cell for camping. If a neighbor cell does not meet the absolute frequency priority cell reselection method, the next candidate neighbor cell is evaluated until a candidate neighbor cell meets the absolute frequency priority cell reselection method.

[0269] If none of the candidate neighboring cells within the candidate neighboring cell range meet the absolute frequency priority cell reselection method, then cell reselection is performed in the neighboring cells measured and obtained by the terminal device. Within the range of neighboring cells measured and obtained by the terminal device, the terminal device determines the target reselection cell according to the absolute frequency priority cell reselection method and selects that cell for camping.

[0270] For example, such as Figure 7 As shown, the terminal device determines the target model identifier set, where the model identifier priority corresponding to AI model identifier 1 is 1. If both neighboring cells C and D, measured by the terminal device, support the highest-priority AI model identifier 1, the device further determines the accuracy level information of the AI ​​model corresponding to AI model identifier 1 among the neighboring cells supporting the highest-priority AI model identifier 1. Based on the comparison, the accuracy level information of the AI ​​model corresponding to AI model identifier 1 in neighboring cell C is relatively the highest. Therefore, neighboring cell C is selected as a candidate neighboring cell, and the absolute frequency priority cell reselection method is used to determine whether neighboring cell C can be used as the target reselection cell for camping.

[0271] Method 2: Select the second application model identifier with the highest priority (i) in the target model identifier set, and determine at least one neighboring cell that supports the second application model identifier and has the highest relative application model accuracy level information as a candidate neighboring cell. Determine the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method. Otherwise, if it is determined that none of the neighboring cells obtained by measurement support the second application model identifier, select the third application model identifier with the highest priority (i+1) in the target model identifier set, and determine at least one neighboring cell that supports the third application model identifier and has the highest relative application model accuracy level information as a candidate neighboring cell. Determine the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method. Otherwise, repeat the previous step until a target reselection cell is determined, where the initial value of i is 1.

[0272] In one possible implementation, the terminal device selects the second application model identifier with the highest priority (i) from the target model identifier set, determines at least one neighboring cell that supports the second application model identifier and has the highest relative application model accuracy level information corresponding to the second application model identifier as a candidate neighboring cell, and determines the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method; otherwise, if it is determined that none of the measured neighboring cells support the second application model identifier, the terminal device selects the third application model identifier with the highest priority (i+1) from the target model identifier set, determines at least one neighboring cell that supports the third application model identifier and has the highest relative application model accuracy level information corresponding to the third application model identifier as a candidate neighboring cell, and determines the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method. If none of the measured neighboring cells support the second and third application model identifiers, the terminal device determines the target reselection cell from all the measured neighboring cells according to the frequency priority cell reselection method.

[0273] In one possible implementation, the terminal device selects the second application model identifier with the highest priority in the target model identifier set, determines at least one neighboring cell that supports the second application model identifier and has the highest relative application model accuracy level information corresponding to the second application model identifier as a candidate neighboring cell, and determines the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method; otherwise, if it is determined that none of the measured neighboring cells support the second application model identifier, the terminal device selects the third application model identifier with the highest priority in the target model identifier set, determines at least one neighboring cell that supports the third application model identifier and has the highest relative application model accuracy level information corresponding to the third application model identifier as a candidate neighboring cell, and determines the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method; otherwise, if it is determined that none of the measured neighboring cells support the third application model identifier, the terminal device selects the fourth application model identifier with the highest priority in the target model identifier set, and so on, performing reselection sequentially according to the priority order of the application model identifiers in the target model identifier set until a target reselection cell is determined.

[0274] Within the candidate neighbor cell range, if a neighbor cell meets the absolute frequency priority cell reselection method, it is considered a suitable neighbor cell, and is selected as the target reselection cell for camping. If a neighbor cell does not meet the absolute frequency priority cell reselection method, the next candidate neighbor cell is evaluated until a candidate neighbor cell meets the absolute frequency priority cell reselection method.

[0275] In one possible implementation, if none of the neighboring cells measured by the terminal device support any of the application model identifiers included in the target model identifier set, the terminal device determines the target reselection cell from all the neighboring cells measured using the absolute frequency priority cell reselection method.

[0276] For example, if none of the candidate neighboring cells within the candidate neighboring cell range meet the absolute frequency priority cell reselection method, then cell reselection is performed in the neighboring cells measured and obtained by the terminal device. Within the range of neighboring cells measured and obtained by the terminal device, the terminal device determines the target reselection cell according to the absolute frequency priority cell reselection method and selects that neighboring cell for camping.

[0277] For example, such as Figure 7 As shown, the terminal device determines the target model identifier set, and the model identifier priority corresponding to AI model identifier 1 is 1. If neither the highest-priority AI model identifier 1 is supported in neighboring cells C and D obtained by the terminal device, the second-highest-priority AI model identifier 2 is selected. Based on the judgment, neighboring cell D supports the second-highest-priority AI model identifier 2, and the AI ​​model accuracy level information corresponding to AI model identifier 2 is relatively the highest. Therefore, neighboring cell D is selected as a candidate neighboring cell, and the absolute frequency priority cell reselection method is used to determine whether neighboring cell D can be used as the target reselection cell for camping.

[0278] In summary, the technical solution provided in this application involves a terminal device determining candidate neighboring cells based on the relationship between the model identifier information of the application models supported by neighboring cells, the accuracy level information of the application models, and the target model identifier set obtained through measurement. Within the determined candidate neighboring cells, the terminal device then determines the target reselection cell using an absolute frequency priority cell reselection method. This technical solution enables the terminal device to select cells that support the application models required by the terminal device, thereby obtaining more accurate cell reselection results and improving the user service experience.

[0279] Figure 14 A flowchart illustrating a cell reselection method provided in an exemplary embodiment of this application is shown. This embodiment applies the method to a terminal device. The method includes:

[0280] Step 1401: The terminal device determines the target model identifier set.

[0281] For example, the target model identifier set refers to the set of identifier information of the application model that the terminal device expects to obtain, and the target model identifier set contains the identifier information of at least one application model.

[0282] Optionally, the target model identifier set determined by the terminal device can be obtained through the terminal device's non-access layer (NAS), or the terminal device's access layer (AS), or through the network device configuration process; this application does not limit this.

[0283] Step 1402: The terminal device performs cell reselection based on the model identifier information of the application model supported by the cell, the priority information of the application model, the accuracy level information of the application model, and the target model identifier set.

[0284] For example, the terminal device performs cell reselection based on the model identifier information of the application models supported by neighboring cells, the priority information of the application models, the accuracy level information of the application models, and the target model identifier set, including at least one of the following two methods:

[0285] Method 1: Select the first application model identifier with the highest priority in the target model identifier set, determine at least one neighboring cell that supports the first application model identifier and whose application model priority information and application model accuracy level information are relatively the highest as candidate neighboring cells, and determine the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method.

[0286] In one possible implementation, the terminal device selects the first application model identifier with the highest priority from the target model identifier set. If it is determined that none of the neighboring cells acquired by measurement support the first application model identifier, the terminal device determines the target reselection cell from the neighboring cells acquired by measurement according to the absolute frequency priority cell reselection method.

[0287] In one possible implementation, the terminal device selects the first application model identifier with the highest priority in the target model identifier set, determines at least one neighboring cell that supports the first application model identifier, and selects at least one neighboring cell among the at least one neighboring cells that supports the first application model identifier as the candidate neighboring cell with the highest relative priority information and application model accuracy level information of the application model corresponding to the first application model identifier. Within the candidate neighboring cell range, the terminal device determines the target reselection cell according to the absolute frequency priority cell reselection method.

[0288] Within the candidate neighbor cell range, if a neighbor cell meets the absolute frequency priority cell reselection method, it is considered a suitable neighbor cell, and is selected as the target reselection cell for camping. If a neighbor cell does not meet the absolute frequency priority cell reselection method, the next candidate neighbor cell is evaluated until a candidate neighbor cell meets the absolute frequency priority cell reselection method.

[0289] If none of the candidate cells within the candidate neighbor cell range meet the absolute frequency priority cell reselection method, then cell reselection is performed in the neighbor cells measured and obtained by the terminal device. Within the neighbor cell range measured and obtained by the terminal device, the terminal device determines the target reselection cell according to the absolute frequency priority cell reselection method and selects that neighbor cell for camping.

[0290] Optionally, selecting at least one neighboring cell with the highest relative priority information and accuracy level information of the application model corresponding to the application model identifier as a candidate neighboring cell means, when the application model has priority information and accuracy level information, selecting at least one neighboring cell with the highest relative priority information and accuracy level information of the application model as a candidate neighboring cell; or, selecting at least one neighboring cell with equal priority information but the highest relative accuracy level information of the application model as a candidate neighboring cell; or, selecting at least one neighboring cell with the highest relative priority information and equal accuracy level information of the application model as a candidate neighboring cell; or, selecting at least one neighboring cell with the highest sum of priority information and accuracy level information of the application model as a candidate neighboring cell. This application does not limit this.

[0291] For example, such as Figure 7 As shown, the terminal device determines the target model identifier set, where the model identifier priority corresponding to AI model identifier 1 is 1. If both neighboring cells C and D, as measured by the terminal device, support the highest-priority AI model identifier 1, the device further determines the priority and accuracy level information of the AI ​​model corresponding to AI model identifier 1 in the neighboring cells supporting the highest-priority AI model identifier 1. The priority information of AI model 1 in neighboring cell C is 1, which is higher than the priority information of AI model 1 in neighboring cell D (2). The accuracy level information of AI model 1 in neighboring cell C is 1, which is higher than the accuracy level information of AI model 1 in neighboring cell D (3). Therefore, neighboring cell C is selected as a candidate neighboring cell, and the absolute frequency priority cell reselection method is used to determine whether neighboring cell C can be used as the target reselection cell for camping.

[0292] Method 2: Select the second application model identifier with the highest priority (i) in the target model identifier set. Determine at least one neighboring cell that supports the second application model identifier and whose application model priority information and application model accuracy level information are relatively the highest as candidate neighboring cells. Determine the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method. Otherwise, if it is determined that none of the neighboring cells obtained by measurement support the second application model identifier, select the third application model identifier with the highest priority (i+1) in the target model identifier set. Determine at least one neighboring cell that supports the third application model identifier and whose application model priority information and application model accuracy level information are relatively the highest as candidate neighboring cells. Determine the target reselection cell from the candidate neighboring cells according to the absolute frequency priority cell reselection method. Otherwise, repeat the previous step until a target reselection cell is determined, where the initial value of i is 1.

[0293] In one possible implementation, the terminal device selects the second application model identifier with the highest priority (i) from the target model identifier set. It then identifies at least one neighboring cell that supports the second application model identifier and whose application model priority information and application model accuracy level information are relatively the highest as candidate neighboring cells. The target reselection cell is then determined from the candidate neighboring cells using an absolute frequency priority cell reselection method. Otherwise, if it is determined that none of the measured cells support the second application model identifier, the terminal device selects the third application model identifier with the highest priority (i+1) from the target model identifier set. It then identifies at least one neighboring cell that supports the third application model identifier and whose application model priority information and application model accuracy level information are relatively the highest as candidate neighboring cells. The target reselection cell is then determined from the candidate neighboring cells using an absolute frequency priority cell reselection method. If none of the measured neighboring cells support the second or third application model identifier, the terminal device determines the target reselection cell from all the measured neighboring cells using a frequency priority cell reselection method.

[0294] In one possible implementation, the terminal device selects the second application model identifier with the highest priority in the target model identifier set, and determines at least one neighboring cell that supports the second application model identifier and whose application model priority information and application model accuracy level information corresponding to the second application model identifier are relatively the highest as candidate neighboring cells. The target reselection cell is determined from the candidate cells according to the absolute frequency priority cell reselection method. Otherwise, if it is determined that none of the measured neighboring cells support the second application model identifier, the terminal device selects the third application model identifier with the highest priority in the target model identifier set, and determines at least one neighboring cell that supports the third application model identifier and whose application model priority information and application model accuracy level information corresponding to the third application model identifier are relatively the highest as candidate neighboring cells. The target reselection cell is determined from the candidate neighboring cells according to the absolute frequency priority cell reselection method. Otherwise, if it is determined that none of the measured neighboring cells support the third application model identifier, the terminal device selects the fourth application model identifier with the highest priority in the target model identifier set, and so on, selecting sequentially according to the priority order of the application model identifiers in the target model identifier set until a target reselection cell is determined.

[0295] Within the candidate neighbor cell range, if a neighbor cell meets the absolute frequency priority cell reselection method, it is considered a suitable neighbor cell, and is selected as the target reselection cell for camping. If a neighbor cell does not meet the absolute frequency priority cell reselection method, the next candidate neighbor cell is evaluated until a candidate neighbor cell meets the absolute frequency priority cell reselection method.

[0296] In one possible implementation, if none of the neighboring cells measured by the terminal device support any of the application model identifiers included in the target model identifier set, the terminal device determines the target reselection cell from all the neighboring cells measured using the absolute frequency priority cell reselection method.

[0297] For example, such as Figure 7As shown, the terminal device determines the target model identifier set, where the model identifier priority corresponding to AI model identifier 1 is 1. If neither neighboring cell C nor neighboring cell D, as measured by the terminal device, supports the highest-priority AI model identifier 1, the second-highest-priority AI model identifier 2 is selected. If neither neighboring cell C nor neighboring cell D supports the second-highest-priority AI model identifier 2, then by analogy, the third-highest-priority AI model identifier 3 is selected. Furthermore, the priority and accuracy level information of the AI ​​model corresponding to AI model identifier 3 are determined. Since the priority and accuracy level information of AI model identifier 3 in neighboring cells C and D are equal, neighboring cells C and D are selected as candidate neighboring cells. The absolute frequency priority cell reselection method is then used to determine whether neighboring cells C and D can be used as target reselection cells for camping.

[0298] In summary, the technical solution provided in this application involves a terminal device determining candidate neighboring cells based on the relationship between the model identifier information, priority information, accuracy level information, and target model identifier set of the application models supported by neighboring cells obtained through measurement. Within the determined candidate neighboring cells, the terminal device then determines the target cell for reselection using an absolute frequency priority cell reselection method. This technical solution enables the terminal device to select cells that support the application models required by the terminal device, thereby obtaining more accurate cell reselection results and improving the user service experience.

[0299] Figure 15 A flowchart illustrating a cell selection method provided in an exemplary embodiment of this application is shown. This embodiment applies the method to a terminal device. The method includes:

[0300] Step 1501: The terminal device receives the first configuration information, which includes the model identifier information of the application model.

[0301] For example, the terminal device receives the first configuration information sent by the network device. It should be noted that the network device may include multiple network devices. After understanding the technical solution of this application, those skilled in the art will easily think of the situation where the network device includes multiple network devices, and these should all fall within the protection scope of this application.

[0302] Optionally, the model identification information of the application model is configured based on frequency point granularity, or the model identification information of the application model is configured based on cell or PCI granularity.

[0303] In one possible implementation, the terminal device receives first configuration information sent by the network device. Table 1 shows the configuration of the serving cell. Table 2 shows the configuration of at least one neighboring cell provided by the serving cell.

[0306] Table 2 shows the configuration of at least one neighboring cell provided by the serving cell, taking the example of the serving cell providing frequency information for two neighboring cells. Each neighboring cell frequency is configured with a set of configurations 2.

Each PCI associated with each neighboring cell frequency is configured with a set of configurations 2.

[0310] Table 3 shows the configuration of at least one neighboring cell provided by the service cell.

[0311]

[0312] In the table, Configuration 2 is the model identifier information for the application model.

[0313] Optionally, the first configuration information is carried via system broadcast messages or dedicated signaling.

[0314] In one possible implementation, the terminal device can obtain configuration information in various ways. The configuration information can be pre-configured in the terminal device's Universal Subscriber Identity Module (USIM). For example, when an operator produces a USIM card, it can pre-configure the configuration information in the USIM so that the terminal device can directly obtain the configuration information when using the USIM card. Alternatively, the configuration information can be carried in a system message and sent to the terminal device. For example, when a network device broadcasts a system message to terminal devices within its service range, it can carry the configuration information in the system message so that the terminal device can obtain the configuration information. Or, the configuration information can be carried in Radio Resource Control (RRC) signaling and sent to the terminal device. For example, when a network device sends an RRC signaling message to a terminal device that has successfully accessed the network device, it can carry the configuration information in the RRC signaling so that the terminal device can obtain the configuration information. This application does not limit this approach.

[0315] In one possible implementation, cell information refers to information used to uniquely identify the cell. Optionally, cell information includes: Physical Cell Identity (PCI) and / or frequency information. That is, in this embodiment, cell information may include only PCI; only frequency information; or both PCI and frequency information. In practical applications, considering processing overhead, only PCI or only frequency information may be used as cell information. Considering the accuracy of identifying a cell, both PCI and frequency information may be used as cell information. This embodiment does not limit this.

[0316] In summary, the technical solution provided in this application embodiment involves a terminal device receiving first configuration information sent by a network device, and the terminal device performing cell selection or cell reselection based on the first configuration information. This technical solution enables the terminal device to select a cell that supports the application model required by the terminal device, thereby obtaining more accurate cell selection or cell reselection results and improving the user service experience.

[0332] Optionally, the accuracy level information of the application model is configured based on frequency point granularity; or, the accuracy level information of the application model is configured based on cell or PCI granularity.

[0333] In one possible implementation, when the same cell supports more than one application model type, there is a one-to-one or one-to-many relationship between the priority information of the application model supported by the cell and the model type of the application model.

[0334] Alternatively, if a cell supports more than one application model type, there may be a one-to-one or one-to-many correlation between the accuracy level information of the application model supported by the cell and the model type of the application model.

[0335] Alternatively, if there are more than one model type for the application model supported in the same cell, there is a one-to-one or one-to-many relationship between the priority information and accuracy level information of the application model supported by the cell and the model type of the application model; that is, one application model type corresponds to a set of model priority information and / or model accuracy level information parameters; or, multiple application model types correspond to a set of model priority information and / or model accuracy level information parameters, and this application does not impose any restrictions on this.

[0336] Optionally, at least one neighboring cell includes at least one of the following: co-frequency neighboring cell, inter-frequency neighboring cell, and inter-system neighboring cell; wherein, co-frequency neighboring cell refers to a neighboring cell with the same frequency as the serving cell; inter-frequency neighboring cell refers to a neighboring cell with a different frequency than the serving cell; inter-system neighboring cell refers to a neighboring cell with a different communication system than the serving cell, such as 4G and 5G systems belonging to different systems.
