[0002] In related technologies, if a terminal device detects that the signal quality of the network is poor, such as weak signal or network freeze, it will directly perform a cell BAR operation on the currently serving cell, that is, set the currently serving cell to a prohibited access state.

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] It should be noted that the terms "including" and "having" and any variations thereof in the embodiments of the present application and the accompanying drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0025] It is understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first cell may be referred to as a second cell, and similarly, a second cell may be referred to as a first cell. Both the first cell and the second cell are areas covered by wireless signals, but they are not the same area. The term "multiple" used in this application refers to two or more.

[0026] Figure 1 FIG. 1 is an application scenario diagram of a cell setting method in an embodiment. Figure 1As shown, a communication connection is established between the terminal device 10 and the network device. Optionally, the terminal device 10 can establish a communication connection with the network device through a fourth generation (4th generation mobile networks, 4G), a fifth generation (5th generation mobile networks, 5G) and other communication technologies, and its communication connection method is not limited in the embodiment of the present application. The network device may include an access network device 20, and one or more core network devices 30 that communicate with the access network device 20.

[0027] In some embodiments, the terminal device 10 may be referred to as user equipment (UE). The terminal device may be a personal communication service (PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), etc. The terminal device may also be a mobile phone, a mobile station (MS), a terminal device (mobile terminal), a laptop computer, etc. The terminal device 10 may communicate with one or more core networks via a radio access network (RAN). For example, the terminal device 10 may be a mobile phone (or a "cellular" phone) or a computer with a terminal device, etc. For example, the terminal device 10 may also be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device, which exchanges voice and / or data with a radio access network. The terminal device 10 may also be a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future evolving network, etc., and the implementation of this application is not limited thereto.

[0028] The access network device 20 can be an evolved base station (evolutional node B, abbreviated as eNB or e-NodeB) macro base station, micro base station (also called "small base station"), pico base station, access point (AP), transmission point (TP) or new generation base station (new generation Node B, gNodeB), etc. in a long-term evolution (LTE) system, a new radio (NR) (mobile communication system) system or an authorized auxiliary access long-term evolution (LAA-LTE) system.

[0029] The core network device 30 may be a Next Generation Core (NGC) device, or an Evolved Packet Core (EPC) device, etc.

[0030] In order to improve the network signal quality of terminal devices on high-speed railways / highways, network operators have deployed corresponding dedicated network equipment for high-speed railways / highways. For example, dedicated communication base stations are deployed along high-speed railway lines to form a high-speed coverage network to ensure the network signal quality of terminal devices in high-speed moving trains and provide passengers with stable and high-speed wireless network services.

[0031] In the related art, when the terminal device is in a high-speed railway / highway scenario, if the terminal device detects that the signal quality of the network is poor, it will directly set the currently served cell to a prohibited access state, and the prohibited access time is relatively long, for example, the currently served cell will be prohibited from access for more than 5 minutes. If the cell currently served by the terminal device is a private network cell of the high-speed railway / highway, after being prohibited from access, it will trigger the terminal device to escape from the currently served cell, which may cause the terminal device to choose a cell that does not belong to the private network cell of the high-speed railway / highway (such as an ordinary public network cell) to reside. Since the cell that does not belong to the private network cell of the high-speed railway / highway usually has more devices connected, it is more prone to network congestion. Therefore, the terminal device will experience a worse network signal quality, which seriously affects the network experience of users on the high-speed railway / highway.

[0032] In an embodiment of the present application, the terminal device 10 is determined to be in a target mobile scenario, which may be a scenario in which the moving speed of the terminal device 10 is greater than a speed threshold. When the network signal quality of the terminal device 10 meets the low quality condition and the first cell currently being served is the private network cell corresponding to the target mobile scenario, the first cell is not set to an access prohibited state. This can increase the probability of the terminal device residing in the private network cell corresponding to the target mobile scenario, reduce the situation in which the network signal quality is worse due to the terminal device choosing to reside in a cell that does not belong to the private network cell corresponding to the target mobile scenario, and improve the user's network usage experience.

[0033] like Figure 2 As shown, in one embodiment, a cell setting method is provided, which can be applied to the above-mentioned terminal device, and the method may include the following steps:

[0034] Step 210: determine whether the terminal device is in a target mobile scenario.

[0035] The target mobile scenario may be a scenario where the moving speed of the terminal device is greater than a speed threshold, for example, the target mobile scenario may include but is not limited to a scenario where the terminal device is on a high-speed train, a scenario where the terminal device is on a high-speed car, etc. Optionally, the speed threshold may be set according to actual needs, such as 120km / h (kilometers per hour), 150km / h, 180km / h, etc., but is not limited thereto.

[0036] In some embodiments, the manner of determining that the terminal device is in the target mobile scene may include, but is not limited to, one or more of the following manners:

[0037] (1) The terminal device can detect the moving speed of the terminal device through a speed sensor and determine whether the moving speed of the terminal device is greater than a speed threshold. If the moving speed of the terminal device is greater than the speed threshold, it can be determined that the terminal device is in the target moving scene.

[0038] (2) The terminal device can obtain travel information, for example, it can obtain the train travel information of the user of the terminal device, the navigation information input by the user, the travel plan input by the user, and other information, and can determine whether the terminal device is currently in the target mobile scenario based on the travel information.

[0039] Exemplarily, the train travel information of the user of the terminal device can be obtained, and the train travel information may include the train departure time, the train arrival time, etc., and it can be determined whether the current time is between the train departure time and the train arrival time. If the current time is between the train departure time and the train arrival time, it can be determined that the terminal device is currently in the target mobile scene (such as a high-speed rail scene).

[0040] Exemplarily, the terminal device can obtain navigation information input by the user and determine the driving route based on the navigation information. It can determine whether the current location of the terminal device is on a highway in the driving route. If the current location of the terminal device is on a highway in the driving route, it can be determined that the terminal device is currently in a target mobile scene (such as a highway scene).

[0041] (3) The terminal device may provide a scene control corresponding to the target mobile scene, and the user may trigger the scene control to select whether to be in the target mobile scene. If the terminal device detects the user's triggering operation on the scene control and determines that the user has selected to be in the target mobile scene, it may be determined that the terminal device is currently in the target mobile scene.

[0042] For example, Figure 3 FIG. 1 is a schematic diagram of an interface for selecting whether to be in a target moving scene in an embodiment. Figure 3 As shown, the scene selection interface 300 may include a target moving scene, such as a high-speed rail scene, and a corresponding scene control 310. The user can select whether to be in the target moving scene (such as a high-speed rail scene) by triggering the scene control 310.

[0043] Whether the terminal device is in the target mobile scene can be detected in a variety of ways, which improves the flexibility and accuracy of determining whether the terminal device is in the target mobile scene.

[0044] Step 220: When the network signal quality of the terminal device meets the low quality condition and the first cell currently being served is a private network cell corresponding to the target mobile scenario, the first cell is not set to an access-prohibited state.

[0045] The terminal device can detect the network signal quality and determine whether the network signal quality meets the low quality condition. The network signal quality can be used to reflect the performance of the network accessed by the terminal device. The higher the network signal quality, the better the network performance accessed by the terminal device, and the better the user's network experience. The lower the network signal quality, the worse the network performance accessed by the terminal device, and the worse the user's network experience.

[0046] Low-quality conditions may refer to conditions used to measure whether the network signal quality is good. When the network signal quality of the terminal device meets the low-quality conditions, it indicates that the network signal quality of the terminal device is poor, and network freezes, weak signals, or no network may occur.

[0047] The network signal quality can be characterized by different indicators. For example, the network signal quality can be characterized by one or more indicators such as RSRP (Reference Signal Received Powe), RSRQ (Reference Signal Received Quality), SNR (Signal-to-Noise Ratio), etc., but is not limited to this.

[0048] In some embodiments, low quality conditions may include any of the following:

[0049] (1) The network signal quality of the terminal device is lower than the quality threshold.

[0050] The terminal device can detect whether the network signal quality is lower than the quality threshold. If it is detected that the network signal quality is lower than the quality threshold, it can be determined that the low quality condition is met.

[0051] Optionally, different quality thresholds may be set for different indicators. For example, the network signal quality may be RSRP, and a strength threshold may be set. The terminal device may measure the RSRP of the wireless network and determine whether the measured RSRP is less than the strength threshold. If the measured RSRP is less than the strength threshold, it is determined that the low quality condition is met.

[0052] (2) The first duration during which the network signal quality of the terminal device is lower than the quality threshold is greater than or equal to the second duration threshold.

[0053] In order to avoid temporary network fluctuations causing the terminal device to suddenly experience a poor network, when the terminal device detects that the network signal quality is lower than the quality threshold, it can record the first duration of the network signal quality lower than the quality threshold, and determine whether the first duration is greater than or equal to the second duration threshold. If the first duration is greater than or equal to the second duration threshold, it means that the terminal device has had poor network signal quality for a period of time, and it is determined that the low quality condition is met. This can improve the accuracy of the terminal device in detecting poor network signal quality.

[0054] Optionally, the second duration threshold may be set according to actual needs, such as 3 seconds, 4 seconds, 6 seconds, etc., but is not limited thereto.

[0055] By detecting the network signal quality and determining whether the network signal quality meets the low-quality conditions, the terminal device can accurately identify situations where the network signal quality is poor, facilitate timely intervention in the network, and avoid the terminal device being in a state of poor network signal quality for a long time, affecting the user's network experience.

[0056] When the terminal device determines that the network signal quality meets the low quality condition, the terminal device can determine whether the first cell currently being served is a private network cell corresponding to the target mobile scenario.

[0057] A cell, also called a cellular cell, refers to an area covered by a base station or part of a base station in a mobile communication system. When a terminal device is in this area, it can communicate with the base station. The first cell currently being served refers to the area covered by the base station currently providing communication services to the terminal device.

[0058] The private network cell corresponding to the target mobile scenario may refer to the area covered by the base station specially set up by the network operator for the target mobile scenario, such as the high-speed railway private network cell, which can be used to provide a private network corresponding to the target mobile scenario for the terminal device in the target mobile scenario to access and use the private network. For example, the private network cell corresponding to the target mobile scenario may include but is not limited to the private network cell corresponding to the high-speed railway scenario and / or the private network cell corresponding to the highway, etc.

[0059] Furthermore, compared with the cell that does not belong to the private network cell corresponding to the target mobile scenario, the private network cell corresponding to the target mobile scenario can provide a more stable and better quality network for the terminal device in the target mobile scenario. Exemplarily, the area covered by the private network cell corresponding to the target mobile scenario can be larger than the area covered by the cell that does not belong to the private network cell corresponding to the target mobile scenario; exemplarily, the network bandwidth of the wireless network provided by the private network cell corresponding to the target mobile scenario can be larger than the network bandwidth of the wireless network provided by the cell that does not belong to the private network cell corresponding to the target mobile scenario, etc. Optionally, the private network cell corresponding to the target mobile scenario can provide a more secure network communication service.

[0060] If the terminal device determines that the first cell currently being served is the private network cell corresponding to the target mobile scenario, the first cell may not be set to a prohibited access state, that is, the BAR cell operation will not be performed on the first cell. The terminal device will not trigger a cell change operation, such as cell reselection or cell switching, due to the prohibition of the first cell currently being served. This can increase the probability of the terminal device continuing to reside in the first cell, that is, increase the probability of the terminal device residing in the private network cell corresponding to the target mobile scenario, and reduce the situation where the terminal device chooses to reside in a cell that does not belong to the private network cell corresponding to the target mobile scenario due to the prohibition of the first cell currently being served, resulting in worse network signal quality.

[0061] It should be noted that, when the terminal device does not set the first cell to a prohibited access state, whether the terminal device performs cell reselection or cell switching can be determined based on the conditions specified in the communication protocol and is not limited here. This can reduce the negative impact caused by excessive intervention of the terminal device in the cell selection in the wireless network.

[0062] In an embodiment of the present application, when the terminal device is in a target mobile scenario with high-speed movement, if the network signal quality of the terminal device is poor, if the first cell currently being served is the private network cell corresponding to the target mobile scenario, the first cell will not be set to an access-prohibited state. This can avoid the situation where the terminal device selects a cell that does not belong to the private network cell corresponding to the target mobile scenario to reside in, resulting in a worse network signal quality due to the private network cell corresponding to the target mobile scenario currently being served being prohibited from access. This can increase the probability of the terminal device residing in the private network cell corresponding to the target mobile scenario, increase the residency ratio of the private network cell corresponding to the target mobile scenario, and improve the user's network usage experience.

[0063] like Figure 4 As shown, in another embodiment, a cell setting method is provided, which can be applied to the above-mentioned terminal device, and the method may include the following steps:

[0064] Step 402: determine whether the terminal device is in a target mobile scenario.

[0065] Step 404, if the terminal device detects that the network signal quality meets the low quality condition, it determines whether the first cell currently being served is a private network cell corresponding to the target mobile scenario. If so, execute step 406, if not, execute step 408.

[0066] The description of steps 402 to 404 may refer to the description of steps 210 to 220 in the above embodiment, and will not be repeated here.

[0067] In some embodiments, when the network signal quality of the terminal device meets the low quality condition, the identification information corresponding to the first cell currently being served can be obtained. If the identification information includes a target identifier, it can be determined that the first cell is a private network cell corresponding to the target mobile scenario.

[0068] Furthermore, the identification information corresponding to the first cell currently being served may be sent by a network device corresponding to the first cell to the terminal device. Optionally, the network device corresponding to the first cell (such as a base station, etc.) may send a system message, and the system message may carry the identification information corresponding to the first cell. The terminal device receives the system message sent by the network device corresponding to the first cell, and may obtain the identification information corresponding to the first cell carried in the system message.

[0069] It should be noted that the timing at which the network device corresponding to the first cell sends the system message is not limited in the embodiment of the present application. For example, the network device corresponding to the first cell may send a system message carrying identification information corresponding to the first cell by periodic broadcasting; for another example, when the terminal device detects that the network signal quality meets the low quality condition, a message request may be sent to the network device corresponding to the first cell currently being served, and the message request is used to request the network device corresponding to the first cell to send a system message. When the network device corresponding to the first cell receives the message request sent by the terminal device, it may respond to the message request and send a system message carrying identification information corresponding to the first cell to the terminal device.

[0070] After the terminal device obtains the identification information corresponding to the first cell, it can determine whether the identification information includes a target identifier, which is used to indicate that the first cell is a private network cell corresponding to the target mobile scenario. If the identification information corresponding to the first cell includes a target identifier, the terminal device can determine that the first cell is a private network cell corresponding to the target mobile scenario.

[0071] If the identification information corresponding to the first cell does not include the target identification, the terminal device can determine that the first cell is not a private network cell corresponding to the target mobile scenario. For example, the first cell can be a public network cell of an NR network or an LTE network. The public network cell refers to the area covered by a public network base station. The public network cell not only provides communication services for terminal devices in the target mobile scenario, but also provides communication services for other terminal devices that are not in the target mobile scenario. Any terminal device can access and use the network. For example, the public network cell around the high-speed railway can also provide network services to the area around the high-speed railway, not just the high-speed railway.

[0072] It should be noted that the target identifier can be set according to actual needs. For example, the target identifier can be an identifier set by a network operator. Optionally, the target identifier can be composed of one or more of numbers, letters, symbols, etc.

[0073] In an embodiment of the present application, the terminal device can determine whether the first cell is a private network cell corresponding to the target mobile scenario based on the identification information corresponding to the first cell. If the identification information includes the target identification, it can be determined that the first cell is the private network cell corresponding to the target mobile scenario. It can accurately identify whether the first cell currently being served is the private network cell corresponding to the target mobile scenario, and perform different network intervention strategies, thereby improving the user's network usage experience.

[0074] Step 406: Do not set the first cell to an access-prohibited state.

[0075] The description of step 406 may refer to the description of step 220 in the above embodiment, and will not be repeated here.

[0076] Step 408: Setting the first cell to be in an access-prohibited state within a target duration.

[0077] When the network signal quality of the terminal device meets the low quality condition and the first cell currently being served is not the private network cell corresponding to the target mobile scenario, the terminal device can set the first cell to be in an access-prohibited state within the target duration, that is, the terminal device can perform a cell BAR operation on the first cell and set the time for which the first cell is prohibited from access as the target duration.

[0078] Among them, the target duration may be less than the first time threshold, and the first time threshold and the target duration may be set according to actual needs. The target duration may be at least less than the duration of the cell BAR operation on the cell in the related technology. Furthermore, the target duration may be a smaller value, for example, the target duration may be 1 second, 2 seconds, etc. By limiting the target duration for which the first cell currently being served is prohibited from access, the time for which the first cell is prohibited from access will not be too long, and the situation that the network of the terminal device is further deteriorated or even no network occurs due to the long-term prohibition of access to the first cell and the lack of access to a cell with better network signal quality can be avoided, thereby improving the user's network experience.

[0079] As a specific implementation, the terminal device sets the first cell to be in a prohibited access state, which may be to set the cell access parameter corresponding to the first cell to prohibited access, for example, the CELL_BAR parameter corresponding to the first cell may be set to barred, etc., but is not limited thereto. In the case where the terminal device sets the first cell to be in a prohibited access state, the terminal device may perform a cell change operation, such as cell switching or cell reselection. For example, if the terminal device is in an idle state, cell reselection may be performed, and if the terminal device is in a connected state, cell switching may be performed to try to select other cells with better network signal quality to reside.

[0080] In some embodiments, the terminal device may set the first cell to a prohibited access state and start a timer for the first cell to be in the prohibited access state, and the duration of the timer may be configured as a target duration.

[0081] The timer can be used to record the time when the first cell is prohibited from access. When the timer times out, that is, when the time length of time that the first cell is set to the prohibited access state is greater than or equal to the target time length, the first cell can be set to the allowed access state, and the cell BAR operation on the access state is canceled. Exemplarily, when the timer times out, the cell access parameter corresponding to the first cell can be set to allowed access, and the CELL_BAR parameter corresponding to the first cell can be set to unbarred, etc., but is not limited to this. It should be noted that after the terminal device sets the first cell to the allowed access state, whether the terminal device will reselect the first cell to reside can be judged according to the provisions of the communication protocol and is not limited here.

[0082] In this implementation, by setting a timer corresponding to the first cell being prohibited from access, the time the first cell is in the prohibited access state can be accurately controlled, and the BAR operation on the cell in the access state can be canceled in time, thereby improving the accuracy of access control on the first cell.

[0083] In an embodiment of the present application, when the network signal quality is poor, if the first cell currently being served is not the private network cell corresponding to the target mobile scenario, the first time duration can be set to be in an access-prohibited state within the target time duration, thereby triggering the terminal device to escape from the first cell and attempt to recover the network. Moreover, since the target time duration is short, it is a relatively small network intervention action and will not bring about a significant negative impact, thereby accelerating the optimization of the network signal quality of the terminal device and improving the user's network usage experience.

[0084] like Figure 5 As shown, in one embodiment, the above method may further include the following steps:

[0085] Step 502: In the next detection cycle, the network signal quality of the terminal device is detected.

[0086] In some embodiments, the terminal device can detect the network signal quality of the terminal device according to a preset detection cycle, and the interval between two adjacent detection cycles can be set according to actual needs, and is not limited here. Each detection cycle can last for a certain period of time, for example, each detection cycle can last for 10 seconds, 12 seconds, 15 seconds, etc., but is not limited thereto.

[0087] If the terminal device detects that the network signal quality meets the low quality condition in the current detection period, if it determines whether the first cell currently served is the private network cell corresponding to the target mobile scenario, if so, the first cell will not be set to a prohibited access state; if not, the first time length will be set to a prohibited access state within the target time length.

[0088] The terminal device may continue to detect the network signal quality of the terminal device in the next detection cycle, and determine whether the network signal quality of the next detection cycle meets the low quality condition. If the network signal quality of the next detection cycle still meets the low quality condition, it means that the network signal quality of the terminal device has not been improved and is still in a poor network state, then further network intervention actions may be performed.

[0089] Step 504: if the network signal quality of the terminal device in the next detection cycle meets the low quality condition, the priority corresponding to the first type of cell is reduced from the first priority to the second priority; the first type is the cell type corresponding to the first cell, and the second priority is lower than the priority corresponding to the second type of cell, so that the terminal device selects the second type of cell to reside.

[0090] Since the terminal device usually gives priority to changing cells between the same type when performing a cell change operation, if the network signal quality of the terminal device in the next detection cycle meets the low quality condition, it means that the cells of the same type may all have the problem of poor network signal quality, and the cell type corresponding to the first cell can be downgraded, and the priority corresponding to the first type of cell can be reduced from the first priority to the second priority. The first type refers to the cell type corresponding to the first cell.

[0091] Furthermore, the second priority may be lower than the priority corresponding to the second type of cell, which is different from the first type. After the priority corresponding to the first type of cell is reduced from the first priority to the second priority, since the second priority is lower than the priority corresponding to the second type of cell, when the terminal device performs a cell change operation, the second type of cell will be preferentially selected for residence, so that the terminal device switches to a different RAT (Radio Access Technology) to try to restore the network signal quality.

[0092] Exemplarily, the first type may be an NR type, and the second type may be an LTE type, that is, the first cell may be an NR cell, and when the network signal quality in the next detection cycle still meets the low quality condition, the priority of the NR cell may be reduced, so that the terminal device can select the LTE cell to reside and access the LTE network for communication. It should be noted that the first type may also be an LTE type, and the second type may also be an NR type, which is not limited here.

[0093] In some embodiments, when the terminal device resides in the second type of cell, if the network signal quality of the terminal device meets the low quality condition, the priority corresponding to the first type of cell is increased from the second priority to the first priority.

[0094] After the terminal device lowers the priority corresponding to the first type of cell, the terminal device selects the second type of cell to reside, and the terminal device can continue to detect the network signal quality and determine whether the detected network signal quality meets the low quality condition. If the terminal device resides in the second type of cell, and the network signal quality of the terminal device still meets the low quality condition, it means that the network signal quality corresponding to the second type of cell is also poor, then the downgrade operation previously performed on the first type of cell can be rolled back, and the priority corresponding to the first type of cell can be increased from the second priority to the first priority.

[0095] After restoring the priority level corresponding to the first type of cell from the second priority level to the first priority level, the terminal device may reselect the first type of cell to reside in, thereby avoiding the situation where the terminal device resides in the second type of cell for a long time resulting in poor network signal quality, and reducing the negative impact of the downgrading operation on the first type of cell.

[0096] In an embodiment of the present application, when the terminal device detects that the network signal quality is poor, after executing the corresponding network intervention strategy, for example, when the first cell currently being served is not the private network cell corresponding to the target mobile scenario, after setting the first time duration to be in an access-prohibited state within the target time duration, the network signal quality is still poor and the network has not recovered, further network intervention actions can be performed to reduce the priority corresponding to the first type of cell so that the terminal device selects the second type of cell to reside, thereby switching to a different RAT, enriching the means for the terminal device to attempt to restore the network without causing too much negative impact, thereby accelerating network recovery and improving the user's network usage experience.

[0097] In some embodiments, after the terminal device determines that the first cell currently being served is the private network cell corresponding to the target mobile scenario and does not set the first cell to a prohibited access state, when the second duration of the network signal quality of the terminal device meeting the low quality condition is greater than or equal to a third duration threshold, or the number of consecutive detections that the network signal quality of the terminal device meets the low quality condition is greater than or equal to a number threshold, if the terminal device still resides in the first cell, the first cell is set to a prohibited access state.

[0098] When the terminal device detects that the network signal quality meets the low quality condition, it can determine whether the first cell currently being served is a private network cell corresponding to the target mobile scenario. If so, the first cell is not set to a prohibited access state. After not setting the first cell to a prohibited access state, the terminal device can continue to detect whether the network signal quality meets the low quality condition.

[0099] If the second duration of the terminal device's network signal quality meeting the low-quality condition is greater than or equal to the third duration threshold, or the number of consecutive detections of the terminal device's network signal quality meeting the low-quality condition is greater than or equal to the number threshold (such as the number of detection cycles in which the connection detects that the terminal device's network signal quality meets the low-quality condition is greater than or equal to the number threshold), it means that the terminal device's network signal quality has been in a poor state for a long time. The terminal device can determine whether it is still resident in the first cell. If the terminal device is still resident in the first cell, although the first cell is a private network cell corresponding to the target mobile scenario, the network corresponding to the first cell is poor. Therefore, the first cell can also be set to be in an access-prohibited state, so that the terminal device performs a cell change operation to escape from the first cell, and chooses other cells to reside in and try to recover the network.

[0100] Compared with cells that do not belong to the private network cells corresponding to the target mobile scenario, the conditions for setting the private network cells corresponding to the target mobile scenario to be in the access prohibited state are more stringent, which can reduce the probability of mistakenly performing cell BAR operations on the private network cells corresponding to the target mobile scenario and improve the accuracy of access control to the cells.

[0101] As an implementation mode, the terminal device may set the first cell to be in an access prohibited state for a first time period. Optionally, the first time period may be less than or equal to the above-mentioned target time period, that is, the time period during which the private network cell corresponding to the target mobile scenario is prohibited from access, and may be less than or equal to the time period during which the private network cell that is not corresponding to the target mobile scenario is prohibited from access. By prohibiting access to the first cell in a shorter period of time, network recovery can be attempted, and the terminal device has less intervention in the network, thereby reducing negative impacts.

[0102] It should be noted that the method of setting the first cell to be in a prohibited access state may be similar to the method of setting the first cell to be in a prohibited access state for a target duration described in the above embodiment. Please refer to the relevant description in the above embodiment and will not be repeated here.

[0103] In an embodiment of the present application, after the terminal device determines that the first cell currently being served is the private network cell corresponding to the target mobile scenario and does not set the first cell to a prohibited access state, if the terminal device has been resident in the first cell and the network of the first cell continues to be in a poor state, the first cell can also be set to a prohibited access state to allow the terminal device to escape from the first cell and attempt to recover the network, thereby further improving the accuracy of the cell's access control and improving the user's network usage experience.

[0104] In some embodiments, the above method may also include: determining at least one candidate cell when the cell change conditions are met; selecting a second cell belonging to a private network cell corresponding to the target mobile scenario from the at least one candidate cell, and changing the currently serving cell from the first cell to the second cell.

[0105] The terminal device may determine whether a cell change condition is met, and the cell change condition may refer to a condition that triggers the terminal device to perform a cell change operation, such as a cell reselection condition, a cell switching condition, etc. If the cell change condition is met, the terminal device may determine at least one candidate cell and select one of the candidate cells to reside in.

[0106] Optionally, the cell change condition may include but is not limited to one or more of the following:

[0107] (1) The real-time location of the terminal device has left or is about to leave the cell range of the first cell.

[0108] The terminal device can locate its real-time position through positioning modules such as GPS (Global Positioning System) and Beidou satellite navigation system. If it is detected that the real-time position of the terminal device has left or is about to leave the cell range of the first cell, a cell change operation can be triggered.

[0109] (2) There is a neighboring cell whose network signal quality is greater than the network signal quality of the first cell, and the difference between the network signal quality of the neighboring cell and the network signal quality of the first cell is greater than the difference threshold.

[0110] The adjacent cell may refer to a cell whose coverage area is adjacent to the area covered by the first cell. The terminal device may detect the network signal quality of one or more adjacent cells of the first cell, and determine whether the network signal quality of each adjacent cell is greater than the network signal quality of the first cell. If the network signal quality of any adjacent cell is greater than the network signal quality of the first cell, it may further determine whether the difference between the network signal quality of the adjacent cell and the network signal quality of the first cell is greater than a difference threshold.

[0111] If the network signal quality of an adjacent cell is greater than that of the first cell, and the difference between the network signal quality of the adjacent cell and that of the first cell is greater than the difference threshold, indicating that there is an adjacent cell with better network signal quality, a cell change operation may be triggered.

[0112] (3) There is a duration during which the network signal quality of the adjacent cell is continuously greater than the network signal quality of the first cell, which is greater than a fourth duration threshold.

[0113] The terminal device can detect the network signal quality of one or more adjacent cells of the first cell, and determine whether the network signal quality of each adjacent cell is greater than the network signal quality of the first cell. If the network signal quality of any adjacent cell is continuously greater than the network signal quality of the first cell for a duration greater than the fourth duration threshold, it indicates that there is an adjacent cell with better network signal quality, and a cell change operation can be triggered.

[0114] (4) The path loss of the first cell is greater than the first loss threshold.

[0115] The path loss of the network can affect the transmission quality of the network signal. The terminal device can obtain the path loss of the first cell and determine whether the path loss of the first cell is greater than the first loss threshold. If the path loss of the first cell is greater than the first loss threshold, it means that the path loss of the first cell is too large and the network signal quality is poor, which can trigger the cell change operation.

[0116] (5) There is an adjacent cell whose path loss is smaller than the path loss of the first cell, and the path loss of the adjacent cell is smaller than a loss threshold.

[0117] The path loss of the network can affect the transmission quality of network signals. The terminal device can obtain the path loss of one or more adjacent cells of the first cell, and determine whether the path loss of each adjacent cell is less than the path loss of the first cell. If the path loss of any adjacent cell is less than the path loss of the first cell, it can further determine whether the path loss of the adjacent cell is less than the loss threshold.

[0118] If the path loss of an adjacent cell is smaller than the path loss of the first cell, and the path loss of the adjacent cell is smaller than the loss threshold, it means that the path loss of the adjacent cell is small and the network signal quality is good, then the cell change operation can be triggered.

[0119] It should be noted that the cell change conditions are not limited to the above conditions, and may also be other conditions, which are not limited here.

[0120] When the cell change conditions are met, the terminal device may determine at least one candidate cell. Optionally, the candidate cell may be a cell with a signal strength greater than a certain strength threshold to ensure normal communication of the terminal device after switching cells.

[0121] Optionally, the terminal device may search and measure the neighboring cells of the first cell when the cell change condition is met, and determine at least one candidate cell from the neighboring cells of the first cell. In this way, the determined candidate cells are more accurate, thereby improving the accuracy of the cell change operation of the terminal device.

[0122] Optionally, since the moving route of the terminal device is usually determined in the target mobile scenario, the cell information corresponding to the moving route can be obtained in advance, and the cell information may include the physical cell identifiers (Physical Cell Identities, PCI) corresponding to each cell that the terminal device may access on the moving route, as well as the geographical location or geographical area corresponding to each cell. When the cell change conditions are met, the cell that the terminal device may access in the future time period can be obtained as a candidate cell based on the cell information corresponding to the moving route. It should be noted that the candidate cell may be an adjacent cell of the first cell, or may not be an adjacent cell of the first cell, which is not limited here. In this way, the terminal device can pre-select a cell that may be accessed in the future time period to reside, which improves the speed of cell change, and can avoid the situation where a new cell is selected but quickly left in a high-speed moving state, resulting in too frequent cell changes, thereby improving the network stability of the terminal device.

[0123] The terminal device can obtain the identification information corresponding to each candidate cell, and determine whether each candidate cell is a private network cell corresponding to the target mobile scenario based on the identification information. If there is a second cell belonging to the private network cell corresponding to the target mobile scenario in the at least one candidate cell, the terminal device can select the second cell to reside, so that the terminal device preferentially resides in the private network cell corresponding to the target mobile scenario, further ensuring the network signal quality of the terminal device in the target mobile scenario.

[0124] Optionally, if there is no second cell belonging to the private network cell corresponding to the target mobile scenario in the at least one candidate cell, the terminal device can select the candidate cell with the best network signal quality to reside in, or the terminal device can select the terminal device with the highest priority, etc., which is not limited here.

[0125] In an embodiment of the present application, when a terminal device performs cell change operations such as cell reselection or cell switching, it can preferentially select a private network cell corresponding to the target mobile scenario to reside in, further ensuring the network signal quality of the terminal device in the target mobile scenario and improving the user's network experience.

[0126] like Figure 6 As shown, in one embodiment, a cell setting device 600 is provided, which can be applied to the above-mentioned terminal device. The cell setting device 600 may include a scene determination module 610 and a setting module 620.

[0127] The scene determination module 610 is used to determine whether the terminal device is in a target movement scene, where the target movement scene is a scene where the movement speed of the terminal device is greater than a speed threshold.

[0128] The setting module 620 is used to not set the first cell to a prohibited access state when the network signal quality of the terminal device meets the low quality condition and the first cell currently being served is a private network cell corresponding to the target mobile scenario.

[0129] In some embodiments, the setting module 620 is also used to set the first cell to be in an access-prohibited state for a target duration when the network signal quality of the terminal device meets a low-quality condition and the first cell currently being served is not a private network cell corresponding to the target mobile scenario; and the target duration is less than the first duration threshold.

[0130] In some embodiments, the setting module 620 is also used to set the first cell to a prohibited access state and start a timer for the first cell to be in the prohibited access state when the network signal quality of the terminal device meets the low quality condition and the first cell currently being served is not a private network cell corresponding to the target mobile scenario. The duration of the timer is configured as the target duration.

[0131] In some embodiments, low quality conditions include any of the following:

[0132] The network signal quality of the terminal device is lower than the quality threshold;

[0133] The first duration during which the network signal quality of the terminal device is lower than the quality threshold is greater than or equal to the second duration threshold.

[0134] In some embodiments, the cell setting device 600 further includes a cell identification module.

[0135] The cell identification module is used to obtain the identification information corresponding to the first cell currently being served when the network signal quality of the terminal device meets the low quality condition; if the identification information includes a target identification, the first cell is determined to be a private network cell corresponding to the target mobile scenario.

[0136] In some embodiments, the cell setting device 600 further includes a signal quality detection module and a priority adjustment module.

[0137] The signal quality detection module is used to detect the network signal quality of the terminal device in the next detection cycle.

[0138] A priority adjustment module is used to reduce the priority corresponding to the first type of cell from the first priority to the second priority if the network signal quality of the terminal device in the next detection cycle meets the low quality condition; the first type is the cell type corresponding to the first cell, and the second priority is lower than the priority corresponding to the second type of cell, so that the terminal device selects the second type of cell to reside.

[0139] In some embodiments, the first type is a new radio NR type, and the second type is a long term evolution LTE type.

[0140] In some embodiments, the priority adjustment module is also used to increase the priority corresponding to the first type of cell from the second priority to the first priority when the terminal device resides in the second type of cell and the network signal quality of the terminal device meets the low quality condition.

[0141] In some embodiments, the setting module 620 is also used to set the first cell to be in an access prohibited state if the terminal device still resides in the first cell when the second continuous duration of the network signal quality of the terminal device meeting the low quality condition is greater than or equal to the third duration threshold, or the number of consecutive detections that the network signal quality of the terminal device meets the low quality condition is greater than or equal to the number threshold.

[0142] In some embodiments, the cell setting device 600 also includes a cell changing module.

[0143] The cell change module is used to determine at least one candidate cell when the cell change conditions are met; select a second cell belonging to the private network cell corresponding to the target mobile scenario from the at least one candidate cell, and change the currently served cell from the first cell to the second cell.

[0144] In an embodiment of the present application, when the terminal device is in a target mobile scenario with high-speed movement, if the network signal quality of the terminal device is poor, if the first cell currently being served is the private network cell corresponding to the target mobile scenario, the first cell will not be set to an access-prohibited state. This can avoid the situation where the terminal device selects a cell that does not belong to the private network cell corresponding to the target mobile scenario to reside in, resulting in a worse network signal quality due to the private network cell corresponding to the target mobile scenario currently being served being prohibited from access. This can increase the probability of the terminal device residing in the private network cell corresponding to the target mobile scenario, increase the residency ratio of the private network cell corresponding to the target mobile scenario, and improve the user's network usage experience.

In addition, the touch panel 732 can be implemented in various types such as resistive, capacitive, infrared, and surface acoustic waves. In addition to the touch panel 732, the input unit 730 may further include other input devices 734.

The display unit 740 may include a display panel 742. Optionally, the display panel 742 may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc. Further, the touch panel 732 may cover the display panel 742. When the touch panel 732 detects a touch operation on or near it, it is transmitted to the processor 780 to determine the type of touch event. Subsequently, the processor 780 provides a corresponding visual output on the display panel 742 according to the type of touch event. Although in Figure 7 In the embodiment, the touch panel 732 and the display panel 742 are used as two independent components to implement the input and output functions of the terminal device, but in some embodiments, the touch panel 732 and the display panel 742 can be integrated to implement the input and output functions of the terminal device.

[0150] The terminal device may also include at least one sensor 750, such as a light sensor, a motion sensor, and other sensors.

As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the terminal device (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured in the terminal device, such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

The audio circuit 760 can transmit the electrical signal converted from the received audio data to the speaker 762, which is converted into a sound signal for output; on the other hand, the microphone 764 converts the collected sound signal into an electrical signal, which is received by the audio circuit 760 and converted into audio data, and then the audio data is output to the processor 780 for processing, and then sent to another terminal device through the RF module 710, or the audio data is output to the memory 720 for further processing.

Optionally, the processor 780 may include one or more processing units; preferably, the processor 780 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications.
