[0103] To enable those skilled in the art to better understand the embodiments of this application, the following description will be provided first.

[0104] 1. Self-Optimizing Experience (SOE);

[0105] Current network-centric data collection and optimization aim to improve overall / average performance at the cell / network level. Currently, terminal-side data can also be used to optimize communication performance or user experience. UE-centric data collection and optimization can reduce the probability of extremely poor user experience and raise the lower limit of user experience levels; this is known as user experience self-optimization.

[0106] 2. The network releases the frequency priority of the message transmission through Radio Resource Control (RRC).

[0107] In related technologies, the network sends frequency priority to the UE through RRC release messages. The RRC release message contains cell reselection priorities, which contain a list of frequency priorities for NR or LTE.

[0108] 3. Priority of network broadcast frequencies;

[0109] In related technologies, the network broadcasts frequency priority through the System Information Block (SIB) 16.

[0110] 4. Community whitelist;

[0111] In the 3rd Generation Partnership Project (3GPP), a "cell whitelist" is a mechanism used to indicate a specific list of cells that a UE can preferentially select or camp on. These cells are typically candidate cells in the network with special attributes or priorities, such as high capacity, low load, or cells serving specific areas. The purpose of the whitelist is to optimize network performance and improve user experience.

[0112] 5. Cell selection (S criterion);

[0113] The S-criterion states that once a cell is measured to satisfy Srxlev>0 AND Squal>0, it can be considered a suitable cell and the user can stay in that cell.

[0114] Where Srxlev represents the Reference Signal Received Power (RSRP) and Squal represents the Reference Signal Received Quality (RSRQ);

[0115] Srxlev=Q rxlevmeas –(Q rxlevmin +Q rxlevminoffset )–P compensation -Q offsettemp ;

[0116] Squal = Q qualmeas –(Q qualmin +Q qualminoffset )-Q offsettemp ;

[0117] Q rxlevmeas : Measure the RSRP value of the cell;

[0118] Q rxlevmin : Minimum received signal level in the cell;

[0119] Q rxlevminoffset : The bias of the lowest received signal level in the cell;

[0120] P compensation : max(P EMAX1 –P PowerClass ,0)(dB);

[0121] Q offsettemp : Applied to temporary offset within this community;

[0122] Q qualmeas : Measure the RSRQ value of the cell;

[0123] Q qualmin Minimum received signal quality for a cell, for example, the minimum received RSRQ required by the cell;

[0124] Q qualminoffset : The offset value for the minimum received signal quality of the cell.

[0125] 6. Criteria for inter-frequency and inter-system cell reselection (R criterion);

[0126] Definition: The process by which a UE, in idle state, monitors the signal quality of neighboring cells and the current cell to access and camp on the best cell.

[0127] The process of re-selecting a neighborhood includes the following:

[0128] Step 1: Determine the cells to be measured: What is the frequency priority? Which cells can be reselected? Which cells need to be measured at the current time?

[0129] Step 2: Determine the cells that meet the reselection requirements: There may be multiple cells that meet the reselection requirements;

[0130] Step 3: Determine the target cell for reselection: Select the final target cell for reselection from the multiple cells obtained in Step 2.

[0131] Step 1, which determines the cells to be measured, includes:

[0132] Step 1-1: Obtain the priority of the reselection frequency points, including the following methods:

[0133] Public priority: The absolute priority of different NR frequency points or different radio access technologies (inter-Radio Access Technology, inter-RAT) frequency points is provided by system information;

[0134] Dedicated priority: Provided by the RRRCRelease message. If the frequency priority is provided by dedicated signaling, the common priority provided by the system information is ignored.

[0135] Inherited from other RATs: During inter-RAT cell selection (reselection), the frequency priority information of the selected RAT is inherited.

[0136] Step 1-2: Determine the scope of the cell reselection;

[0137] The UE will only perform cell reselection assessments on the NR and inter-RAT frequency points provided in the system information;

[0138] Reselection will not consider communities on the blacklist;

[0139] Reselection will only consider communities in the whitelist (if a whitelist is configured);

[0140] Reselection measurements involve measurements of cells with the same frequency, cells with different frequencies, and cells with different systems.

[0141] Steps 1-3: Determine the measurement range at the current moment;

[0142] For same-frequency measurements:

[0143] If the serving cell satisfies Srxlev>S IntraSearchP And Squal>S IntraSearchQ If the UE does not perform the same-frequency measurement, then the UE will not perform the same-frequency measurement; otherwise, the UE will perform the same-frequency measurement.

[0144] Among them, S IntraSearchP and S IntraSearchQ It is the threshold for starting the same frequency measurement.

[0145] For measurements of different frequencies or different systems:

[0146] If the frequency point of a different frequency or system has a higher priority than the current frequency point, then the measurement of the different frequency or system will be performed.

[0147] If the frequency priority of a different frequency or system is equal to or lower than the current frequency;

[0148] If the serving cell satisfies Srxlev>S nonIntraSearchP And Squal>S nonIntraSearchQ If the UE does not perform inter-frequency or inter-system measurements on these frequencies, then the UE will not perform inter-frequency or inter-system measurements on these frequencies; otherwise, the UE will perform inter-frequency or inter-system measurements on these frequencies.

[0149] Among them, S nonIntraSearchP and S nonIntraSearchQ It is the threshold for starting measurements across different frequencies / systems.

[0150] Among them, the reselection cells that meet the requirements identified in Step 2 above include:

[0151] Inter-frequency and inter-system cell reselection criteria:

[0152] For high-priority frequency points, the reselection requirement is met if the following two conditions are met;

[0153] Treselection at specified time RAT Within this range, the signal strength Srxlev > Thresh is always satisfied. X,HighP Or signal quality Squal>Thresh X,HighQ ;

[0154] The UE camps on the source cell for more than 1 second;

[0155] Among them, TreselectionRAT The parameter specifies the value of the cell reselection timer. A specific cell reselection timer value is defined for each target NR frequency and for each RAT other than NR. This value is used to evaluate reselection within the NR or to other RATs (i.e., Treselection for NR). RAT For Treselection NR For E-UTRAN Treselection RAT For Treselection EUTRA ).

[0156] It should be noted that: Treselection RAT It will not be broadcast in the system information, but will be used by the UE in the reselection rules of each RAT.

[0157] For frequencies with the same priority, the reselection criteria are the same as those for frequencies with the same priority:

[0158] Service cell ranking criteria: R s =Q meas,s +Q hyst -Q offsettemp ;

[0159] Neighbor sorting criterion: R n =Q meas,n -Qoffset-Qoffset temp ;

[0160] The reselection requirement is met if the neighboring cell meets the following two conditions:

[0161] Target cell at specified time Treselection RAT The inner R value is consistently higher than that of the serving cell;

[0162] The UE stayed in the serving cell for more than 1 second.

[0163] For low-priority frequency points, the reselection requirement is met if the following two conditions are satisfied:

[0164] Treselection at specified time RAT Within the source cell, the signal strength Srxlev is always satisfied. <Thresh Serving,LowP or signal quality Squal <Thresh Serving,LowQ And the target frequency always satisfies Srxlev > Thresh X,LowP Or Squal>Thresh X, LowQ;

[0165] The UE resides in the source cell for more than 1 second.

[0166] The step 3 above, which determines the target cell for reselection, includes:

[0167] (1) For high-priority frequency points: prioritize reselection;

[0168] (2) For frequencies with the same frequency and priority:

[0169] Sort by R value and select the best cells with signal quality within the rangeToBestCell range;

[0170] Then, the cell with the most beams that exceed the threshold absThreshSS-BlocksConsolidation is selected as the target cell;

[0171] (3) For low priority frequency points: Consider when there are no high priority frequency points or frequency points of the same priority that meet the requirements.

[0172] 7. Cell handover A3 event;

[0173] Entry conditions for event A3:

[0174] Mn+Ofn+Ocn–Hys>Mp+Ofp+Ocp+Off;

[0175] Conditions for leaving the A3 event:

[0176] Mn+Ofn+Ocn+Hys <Mp+Ofp+Ocp+Off;

[0177] The conditions for triggering the reporting of an A3 event are as follows:

[0178] The entry condition for the A3 event is always met within the TimeToTrigger;

[0179] Conditions for leaving the event:

[0180] The exit condition of event A3 is always met within TimeToTrigger;

[0181] The relevant parameters for event A3 are described in Table 1.

[0185] Currently, there are some special scenarios in communication network deployments, such as elevator scenarios. In elevator scenarios, user terminals may experience a drop to 2G / 3G or Out-of-service (OOS) situations inside the elevator due to network coverage issues. After exiting the elevator, in most cases the network will restore Long Term Evolution (LTE) / Standalone (SA) coverage, but the terminal cannot immediately resume 4G / 5G network connectivity.

[0186] Suppose that the terminal obtains frequency priority list 1 from cell 1 before entering the elevator. Then, it is in an OOS (Out of Service) state inside the elevator. After exiting the elevator, if the terminal uses frequency priority list 1 obtained from cell 1 to search for a frequency point, there will be a problem where a suitable cell cannot be found in a timely manner if the frequency priority of the cell after exiting the elevator is inconsistent with the frequency priority list obtained from cell 1. This is because the UE's position has moved, and the validity of frequency priority list 1 has changed.

[0187] The difference between elevator scenarios and high-speed rail tunnel scenarios lies in the fact that when a terminal travels through a high-speed rail tunnel, its movement trajectory is fixed. Therefore, a whitelist can be used to help the UE select frequency points. However, in an elevator scenario, the UE's movement trajectory changes depending on the floor it exits. Therefore, the network cannot provide frequency priority to the terminal using a whitelist.

[0188] The information transmission method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0189] like Figure 2 As shown in the figure, this application provides an information transmission method, including:

[0190] Step 201: The terminal obtains at least one of the first information and the second information sent by the first network-side device;

[0191] The first information includes first configuration information, and at least one of the identifier of a first scenario associated with the first configuration information and first location-related information. The first configuration information includes at least one of frequency priority information, cell selection information, cell reselection information and cell handover information. The first scenario is related to a first means of transport carrying the terminal, and the first location-related information is used to indicate at least one location.

[0192] The second information includes configuration information of the first report, the first report being related to the first event, the first event being associated with at least one of the identifier of the second scenario and the second location-related information, and at least one of the second scenario and the second location-related information being related to the first means of transport carrying the terminal;

[0193] The cell selection message includes information for the terminal to select a cell;

[0194] The cell reselection information includes information used by the terminal to perform cell reselection.

[0195] The cell handover information includes information used by the terminal to perform cell handover.

[0196] The first scenario mentioned above can also be described as a first transportation scenario, and the second scenario mentioned above can also be described as a second transportation scenario. The first scenario and the second scenario can also be described as a special scenario or a special transportation scenario.

[0197] In this embodiment of the application, the first network-side device includes a base station.

[0198] (1) For the identifier (ID) of the first scenario mentioned above:

[0199] The signal penetration loss and other wireless propagation characteristics differ significantly depending on whether the terminal is located inside or outside the first means of transportation (such as an elevator), making it impossible to apply the same frequency priority. Determining whether the terminal is inside or outside the first means of transportation beforehand helps it obtain accurate frequency priority.

[0200] When a terminal enters a first mode of transportation (such as an elevator), the closing of the door causes a sudden change in the wireless signal. If the terminal can quickly camp on a more suitable cell (e.g., by configuring a lower cell selection threshold and / or a shorter timer or window duration), the inability to find a network can be avoided. However, if the terminal does not enter the first mode of transportation but merely passes by its outside, this problem does not exist. Therefore, different cell selection parameters corresponding to different first-scenario identifiers are beneficial for the terminal to reselect a more suitable cell in different first-scenario scenarios.

[0201] When a terminal enters a first mode of transportation (such as an elevator), the closing of the door causes a sudden change in the wireless signal. If the terminal can switch to a more suitable cell more quickly (e.g., by configuring a lower cell selection threshold and / or a lower timer or window duration), dropped calls can be avoided. However, if the terminal does not enter the first mode of transportation but merely passes by its exterior, this problem does not exist. Therefore, different first-scenario identifiers corresponding to different cell handover parameters are beneficial for the terminal to switch to a more suitable serving cell in different first-scenario scenarios.

[0202] When a terminal leaves a first means of transportation (such as an elevator), if the terminal experiences a wireless link failure while inside the first means of transportation, or if it leaves a container with high penetration loss, the wireless signal will change abruptly. If the terminal can camp on a suitable cell more quickly (e.g., by configuring a lower cell selection threshold and / or a shorter timer or window duration), it can find a suitable network more quickly. However, if the terminal does not enter the first means of transportation but merely passes by its outside, the above problem does not exist. Therefore, different cell selection parameters corresponding to different first-scenario identifiers are beneficial for the terminal to camp on a suitable serving cell in different first-scenario scenarios.

[0203] (2) Regarding the information related to the first position mentioned above;

[0204] Frequency priorities differ depending on the terminal's location. Using location-related information helps the terminal determine the appropriate frequency priority, thus enabling it to camp on a suitable cell or switch to a suitable serving cell more quickly.

[0205] Cell selection parameters can vary depending on the terminal's location. Using location-related information helps the terminal determine appropriate cell selection parameters, thereby helping the terminal camp on a suitable cell more quickly.

[0207] Cell handover parameters can vary depending on the terminal's location. Using location-related information helps the terminal determine appropriate handover parameters, thus enabling it to switch to a suitable serving cell more quickly.

If they match, the terminal location associated with the third location-related information (cell selection information, frequency priority information) is determined based on the (cell selection information, frequency priority information) associated with the first location-related information.

[0403] In some embodiments of this application, after the terminal obtains the first information sent by the first network-side device, the above information transmission method further includes:

[0404] The terminal acquires third information, which includes third location-related information, or includes third location-related information and a third scene identifier;

[0405] If the first condition is met, the terminal will not perform a network search;

[0406] The first condition includes at least one of the following:

[0407] The first location-related information associated with the frequency priority information does not include the third location-related information.

[0408] The frequency priority information corresponding to the third location-related information is an empty set;

[0409] The first scenario associated with the frequency priority information does not include the third scenario;

[0410] The frequency priority information corresponding to the third scenario is an empty set.

[0411] In this embodiment of the application, if the second condition described above is met, the terminal may not perform frequency point search or network search in order to save power consumption.

[0412] In some embodiments of this application, after the terminal obtains the second information sent by the first network-side device, the above information transmission method further includes:

[0413] The terminal sends fourth information to the first network-side device or the second network-side device, the fourth information including the first report, the first report including at least one of the following related to the first event:

[0414] The signage for the second scene;

[0415] The identifier of the second business;

[0416] Information related to the second position;

[0417] The identifier of the first event;

[0418] The associated ID of the service cell;

[0419] The associated ID of adjacent cells;

[0420] At least one measured cell identifier and channel quality.

[0421] The at least one measured cell identifier and channel quality can serve as supplementary information for recommending frequency priority to subsequent terminals.

[0422] In this embodiment of the application, if the network-side device is configured to trigger event reporting in the second information, the terminal detects whether a first event has occurred. If a first event has occurred, the terminal records the information related to the first event and sends the first report to the first network-side device or the second network-side device.

[0423] In some implementations of this application, if the network-side device is configured to periodically report in the second information, the UE will periodically send a first report to the first network-side device;

[0424] In some implementations of this application, if the network-side device configures logging configuration and periodic recording in the second information, the UE will periodically record the relevant information of the first report configuration instruction, and after receiving the first instruction sent by the first network-side device or the second network-side device, send the first report to the first network-side device or the second network-side device.

[0425] In some implementations of this application, if the network-side device configures logging configuration and a first event in the second information, the UE will record the first event and related information when the first event is met. Upon receiving a first instruction from the first or second network-side device, the UE will send a first report to the first or second network-side device.

[0426] The aforementioned second network-side device can be a base station or a core network device. The aforementioned first network-side device and second network-side device can be the same. The first network-side device and the second network-side device can be co-located. When the first network-side device and the second network-side device are the same or co-located, the first network-side device can perform the operations performed by the second network-side device.

[0427] In some implementations, the first network-side device can be at least one of the following:

[0428] The network equipment corresponding to the serving cell or the cell where the terminal is stationed before entering the first scenario;

[0429] The network equipment corresponding to the serving cell or camped cell before the terminal experiences the first event;

[0430] The network device corresponding to the serving cell or camped cell when the terminal experiences the first event;

[0431] In some implementations, the second network-side device can be at least one of the following:

[0432] The network equipment corresponding to the serving cell after the terminal leaves the first scenario;

[0433] The network device corresponding to the serving cell when the terminal enters the connected state after the first event occurs;

[0434] The network equipment corresponding to the serving cell after the terminal experiences the first event.

[0435] In some implementations, the first network-side device can be the network device corresponding to the serving cell before the terminal enters the first transportation scenario, and the second network-side device can be the network device corresponding to the serving cell after the terminal leaves the first transportation scenario. Alternatively, in some implementations, the first network-side device can be the network device corresponding to the serving cell before the terminal experiences the first event, and the second network-side device is the network device requesting the second report. Or, the first network-side device can be the network device corresponding to the serving cell or the cell where the terminal is camped at the time the first event occurs, and the second network-side device is the network device requesting the second report. That is, in the embodiments of this application, the network device obtaining the second report and the network device sending the first information can be different.

[0436] Furthermore, in this embodiment, the first network-side device and the second network-side device may correspond to the same cell or different cells. When the first network-side device and the second network-side device correspond to the same cell, the first network-side device can perform the operations performed by the second network-side device.

[0437] In some embodiments of this application, the above-described information transmission method further includes:

[0438] The terminal obtains a first instruction sent by the first network-side device or the second network-side device, the first instruction being used to instruct the terminal to send the first report.

[0439] In this embodiment of the application, the first scenario, the second scenario, or the third scenario described above each include at least one of the following:

[0440] The terminal is inside the first means of transport;

[0441] The terminal is outside the first means of transport;

[0442] The terminal enters the first means of transport;

[0443] The terminal leaves the first transport vehicle;

[0444] The terminal enters and exits the first means of transport;

[0445] The terminal passed by but did not enter the first transport vehicle.

[0446] In some embodiments of this application, the second information includes at least one of the following:

[0447] (1) The identifier of the second scene;

[0448] The signal penetration loss and other wireless propagation characteristics differ significantly depending on whether the terminal is located inside or outside the first means of transportation (such as an elevator), making it impossible to apply the same frequency priority. Determining whether the terminal is inside or outside the first means of transportation beforehand is beneficial for recording the wireless environment in which events such as slow network search occur.

[0449] (2) Identification of the second business;

[0450] The second service includes voice services, video calls, live streaming, gaming, and web browsing. Different services have different requirements for metrics such as latency, packet loss rate, and data rate. Identifying this second service allows the UE to record failure events based on specific services. By adding conditions to trigger recording, the information that needs to be recorded can be filtered, thereby reducing the number of events that need to be recorded and lowering the UE's storage requirements.

[0451] (3) Information related to the second position;

[0452] The UE's location information is useful for marking the specific location where network search failures such as slow network search occur. This is beneficial for obtaining more accurate frequency priority, and / or cell selection information, and / or cell reselection information, and / or cell handover information when other UEs pass through the same location later, based on auxiliary information provided by the network.

[0453] (4) Identification of the first event;

[0454] The identification of this first event helps the UE to record based on specific failure events, thereby helping the UE to increase the conditions for triggering recording, filter the information that needs to be recorded, and thus reduce the number of events that need to be recorded and reduce the storage requirements of the UE.

[0455] (5) Parameter values ​​related to the first event;

[0456] This information includes the threshold for triggering the first event, and / or the duration of the timer or window, which can help adjust the conditions for triggering the first event.

[0457] If you want to collect a large number of first events, you can lower the threshold parameter for triggering the first event, and / or shorten the duration of the timer or window.

[0458] To collect more accurate first events, you can increase the threshold parameter for triggering the first event, and / or lengthen the timer or window duration.

[0459] (6) The associated ID of the serving cell;

[0460] If the UE indirectly records its location via radio frequency fingerprinting, it is beneficial to record under what network device configuration (e.g., antenna, beam configuration) the measured serving cell channel quality was obtained.

[0461] If the measurement results of the serving cell recorded by the UE are related to the configuration of the network equipment of the serving cell, it is beneficial to record under which network equipment configuration (e.g., antenna, beam configuration) the measured channel quality of the serving cell was obtained.

[0462] (7) The associated ID of adjacent cells.

[0463] When a UE indirectly records its location via radio frequency fingerprinting, it is beneficial to record under what network device configuration (e.g., antenna, beam configuration) the measured neighboring cell channel quality was obtained.

[0464] If the measurement results of neighboring cells recorded by the UE are related to the configuration of the network equipment in the neighboring cells, it is beneficial to record under which network equipment configuration (e.g., antenna, beam configuration) the measured serving cell channel quality was obtained.

[0465] In some embodiments of this application, the above-described information transmission method further includes:

[0466] If the second condition is met, the first report is generated;

[0467] The second condition includes at least one of the following:

[0468] The identifier of the scene identified by the terminal matches the identifier of the second scene in the second information;

[0469] The terminal's service identifier matches the identifier of the second service in the second information;

[0470] The first event detected by the terminal matches the first event in the second information.

[0471] Triggering the generation of the first report by using the aforementioned first condition helps reduce the storage requirements on the terminal side and also facilitates the recording of specific events required by the network.

[0472] In some embodiments of this application, the cell selection information includes at least one set of S-criteria parameters, and the parameters of the at least one set of S-criteria in the cell selection information are associated with at least one of the identifier of the first scenario and the first location-related information.

[0473] The parameters of the S-criterion include at least one of the following:

[0474] Temporary relocation of the community;

[0475] Minimum received signal level in the cell;

[0476] The bias Q of the lowest received level in the cell rxlevminoffset ;

[0477] Penalty value for UEs that do not reach the cell's maximum power;

[0478] Minimum received signal quality for the cell;

[0479] The minimum received signal quality offset Q of the cell qualminoffset .

[0480] For example, the cell selection information includes parameters of two sets of S criteria, wherein one set of S criteria parameters is associated with at least one of the identifier of the first scenario and the first location-related information, while the other set of S criteria parameters is not associated with the identifier of the first scenario and the first location-related information.

[0481] For example, the terminal receives two sets of S-criterion parameters outside the first means of transportation (e.g., elevator). One set is applicable to the current moment, while the other set is related to the scenario when exiting the elevator (first scenario) and the floor exiting the elevator (first position).

[0482] For example, the cell selection information includes parameters of three sets of S criteria. The parameters of the first set of S criteria are associated with the location of the first terminal, the parameters of the second set of S criteria are associated with the location of the second terminal, and the parameters of the third set of S criteria are not associated with the location of the terminal.

[0483] For example, the terminal receives three sets of S-criterion parameters outside the first means of transportation (e.g., elevator). One set is applicable to the current moment, while the other two sets are related to the scenario when exiting the elevator (first scenario) and the floor exiting the elevator (first position).

[0484] For example, the cell selection information includes parameters of three sets of S criteria. The parameters of the first set of S criteria are associated with the location of the first terminal, the parameters of the second set of S criteria are associated with the location of the second terminal, and the parameters of the third set of S criteria are associated with the location of the third terminal.

[0485] For example, the terminal receives three sets of S-criterion parameters outside the first means of transportation (e.g., elevator). The first set is applicable inside the elevator (first terminal position), while the other two sets are related to the scenario when exiting the elevator (first scenario) and the different floors exiting the elevator (second terminal position, third terminal position).

[0486] The cell selection information described above enables the terminal to select appropriate S-criterion parameters for cell selection based on the scenario or terminal location. This facilitates faster UE camping on suitable cells in scenarios related to the primary mode of transportation.

[0487] In some embodiments of this application, the cell reselection information includes at least one set of cell reselection parameters, and the at least one set of cell reselection parameters in the cell reselection information is associated with at least one of the identifier of the first scenario and the first location-related information.

[0488] The set of parameters for cell reselection includes at least one of the following:

[0489] Same-frequency measurement start threshold;

[0490] Different frequency measurement start threshold

[0491] Inter-system measurement start threshold;

[0492] The value of the cell reselect timer;

[0493] Signal strength threshold for cell reselection;

[0494] Signal quality threshold for cell reselection;

[0495] Threshold for the duration of terminal residing in the source cell.

[0496] For example, the cell reselection information includes two sets of cell reselection parameters. One set of cell reselection parameters is associated with at least one of the identifier of the first scenario and the first location-related information, while the other set of cell reselection parameters is not associated with the identifier of the first scenario and the first location-related information.

[0497] For example, cell reselection information includes three sets of cell reselection parameters. The first set of cell reselection parameters is associated with the location of the first terminal, the second set of cell reselection parameters is associated with the location of the second terminal, and the third set of cell reselection parameters is not associated with the terminal location.

[0498] For example, cell reselection information includes three sets of cell reselection parameters. The first set of cell reselection parameters is associated with the location of the first terminal, the second set of cell reselection parameters is associated with the location of the second terminal, and the third set of cell reselection parameters is associated with the location of the third terminal.

[0499] The aforementioned cell reselection information enables the terminal to select appropriate cell reselection parameters based on the scenario or terminal location. This facilitates faster cell reselection for the UE in scenarios related to the primary mode of transportation.

[0500] In some embodiments of this application, the cell handover information includes at least one set of cell handover parameters, and the at least one set of cell handover parameters in the cell handover information is associated with at least one of the identifier of the first scenario and the first location-related information;

[0501] The set of parameters for cell handover includes at least one of the following:

[0502] The specific offset of the neighboring cell measurement object;

[0503] Cell-specific offset of neighboring cells;

[0504] Hysteresis;

[0505] The specific offset of the measurement object in the serving cell;

[0506] The cell-specific offset of the serving cell;

[0507] A3 event offset;

[0508] Event timer.

[0509] For example, cell handover information includes two sets of cell handover parameters. One set of cell handover parameters is associated with at least one of the identifier of the first scenario and the first location-related information, while the other set of cell handover parameters is not associated with the identifier of the first scenario and the first location-related information.

[0510] For example, cell handover information includes three sets of cell handover parameters. The first set of cell handover parameters is associated with the location of the first terminal, the second set of cell handover parameters is associated with the location of the second terminal, and the third set of cell handover parameters is not associated with the terminal location.

[0511] For example, cell handover information includes three sets of cell handover parameters. The first set of cell handover parameters is associated with the location of the first terminal, the second set of cell handover parameters is associated with the location of the second terminal, and the third set of cell handover parameters is associated with the location of the third terminal.

[0512] The aforementioned cell handover information enables the terminal to select appropriate cell handover parameters based on the scenario or terminal location. This facilitates faster handover of the UE to a suitable serving cell in scenarios related to the primary mode of transportation.

[0513] The information transmission method of this application will be described below with reference to embodiments.

[0514] Example 1: Event reporting and auxiliary information provision in an elevator scenario;

[0515] Example 1-1: Elevator exit scenario - event reporting;

[0516] like Figure 3As shown, assume that the terminal obtains frequency priority list 1 from cell 1 before entering the elevator. Then, it is in an OOS (Out of Service) state inside the elevator. After exiting the elevator, if the terminal uses frequency priority list 1 obtained from cell 1 to search for a frequency point, but the actual cell frequency priority after exiting the elevator is inconsistent with the frequency priority list obtained from cell 1 due to the change in the terminal's location, there will be a problem of not being able to find a suitable cell in a timely manner. Example 1-1 assumes that when the UE encounters an inability to find a suitable cell, it will record the event and report it to the network, preventing other UEs from encountering the same problem when passing through the same location. This allows for optimization of the UE's network search effectiveness based on historical events.

[0517] like Figure 4 As shown, the corresponding signaling flow includes:

[0518] Step 1 (optional): The UE receives second information sent by the first network-side device, the second information being used to configure the first report. The second information includes at least one of the following:

[0519] A1: Identifier (ID) for special scenarios, namely the identifier for the second scenario mentioned above;

[0520] The signal penetration loss and other wireless propagation characteristics differ significantly depending on whether the terminal is located inside or outside the first means of transportation (such as an elevator), making it impossible to apply the same frequency priority. Determining whether the terminal is inside or outside the first means of transportation beforehand is beneficial for recording the wireless environment in which events such as slow network search occur.

[0521] A2: Information related to the second position;

[0522] The UE's location information is useful for marking the specific location where network search failures such as slow network search occur. This is beneficial for obtaining more accurate frequency priority, and / or cell selection information, and / or cell reselection information, and / or cell handover information when other UEs pass through the same location later, based on auxiliary information provided by the network.

[0523] A3: Identifier for the second business;

[0524] The second service includes voice services, video calls, live streaming, gaming, and web browsing. Different services have different requirements for metrics such as latency, packet loss rate, and data rate. Identifying this second service allows the UE to record failure events based on specific services. By adding conditions to trigger recording, the information that needs to be recorded can be filtered, thereby reducing the number of events that need to be recorded and lowering the UE's storage requirements.

[0525] A4: Identifier of the first event;

[0526] The identification of this first event helps the UE to record based on specific failure events, thereby helping the UE to increase the conditions for triggering recording, filter the information that needs to be recorded, and thus reduce the number of events that need to be recorded and reduce the storage requirements of the UE.

[0527] A5: The associated ID of the serving cell;

[0528] If the UE indirectly records its location via radio frequency fingerprinting, it is beneficial to record under what network configuration (e.g., antenna, beam configuration) the measured serving cell channel quality was obtained.

[0529] If the measurement results of the serving cell recorded by the UE are related to the configuration of the network equipment of the serving cell, it is beneficial to record under which network equipment configuration (e.g., antenna, beam configuration) the measured channel quality of the serving cell was obtained. A6: Association ID of neighboring cells;

[0530] If the UE indirectly records its location via radio frequency fingerprinting, it is beneficial to record under what network configuration (e.g., antenna, beam configuration) the measured neighboring cell channel quality was obtained.

[0531] If the measurement results of neighboring cells recorded by the UE are related to the network equipment configuration of the neighboring cells, it is beneficial to record under which network equipment configuration (e.g., antenna, beam configuration) the measured serving cell channel quality was obtained. The identifier for the above special scenario can be used to indicate at least one of the following:

[0532] The terminal is inside the first means of transport;

[0533] The terminal is outside the first means of transport;

[0534] The terminal enters the first means of transport;

[0535] The terminal leaves the first transport vehicle;

[0536] The terminal enters and exits the first means of transport;

[0537] The terminal passed by but did not enter the first transport vehicle.

[0538] The aforementioned first means of transport is a means of transport, including at least one of the following:

[0539] elevator;

[0540] High-speed train carriage;

[0541] subway car;

[0542] Boat;

[0543] The cabin.

[0544] The first event mentioned above is an event related to a deterioration or failure in wireless transmission quality, including at least one of the following:

[0545] Wireless link failure;

[0546] Voice call dropped;

[0547] Searching the web is too slow;

[0548] OOS.

[0549] Step 2: The UE checks whether the first event has occurred.

[0550] Step 3: The UE determines whether to record information related to the first event. The determination condition includes at least one of the following:

[0551] The UE measures and identifies the identifier of the second scene, which is matched with the identifier of the first scene in the first information;

[0552] The UE's service identifier matches the identifier of the second service in the second information;

[0553] The first event measured and identified by the UE is matched with the first event in the first information.

[0554] If it is determined that the information related to the first event is to be recorded, the UE will include at least one of the following information in the first report:

[0555] The signage for the second scene;

[0556] The identifier of the second business;

[0557] Information related to the second position;

[0558] The identifier of the first event;

[0559] The associated ID of the service cell;

[0560] The associated ID of adjacent cells;

[0561] At least one measured cell identifier and channel quality.

[0562] The at least one measured cell identifier and channel quality can serve as supplementary information for recommending frequency priority to subsequent terminals.

[0563] Triggering the generation of the first report by using the aforementioned first condition helps reduce the storage requirements on the terminal side and also facilitates the recording of specific events required by the network.

[0564] Step 4 (optional): The UE receives a first indication sent by the second network-side device, the first indication being used to instruct the terminal to send the first report. Optionally, the first request may further include at least one of the following:

[0565] The request information for the identifier of the second scenario;

[0566] The request information for the identifier of the second service;

[0567] Request information related to the second location;

[0568] The request information for identifying the first event;

[0569] Request information for the associated ID of the serving cell;

[0570] Request information for the associated IDs of neighboring cells;

[0571] A request for at least one measured cell identifier and channel quality information.

[0572] Step 5: The UE sends fourth information to the second network-side device, the fourth information including a first report. The first report includes at least one of the following:

[0573] The signage for the second scene;

[0574] The identifier of the second business;

[0575] Information related to the second position;

[0576] The identifier of the first event;

[0577] The associated ID of the service cell;

[0578] The associated ID of adjacent cells;

[0579] At least one measured cell identifier and channel quality. For example, the cell identifier and channel quality could be obtained after a long search period, or the identifier and channel quality of a cell after connection recovery. This at least one measured cell identifier and channel quality can serve as supplementary information for recommending frequency priority to subsequent UEs.

[0580] In this embodiment of the application, when providing the UE's location based on radio frequency fingerprint, the channel quality information measured by the UE is related to the antenna or beam configuration of the network device. If the antenna configuration or beam configuration of the network device changes, the channel quality of multiple cells measured by the UE will also change. The association ID of the serving cell or the association ID of the neighboring cells is beneficial to the consistency between the data characteristics of the auxiliary information provided subsequently and the data characteristics of the radio frequency identification information.

[0581] The information related to the second position includes at least one of the following:

[0582] (1) Vertical height information of the terminal when the first event occurs;

[0583] In elevator scenarios, the UE mainly moves in the vertical direction. Based on the vertical height information of the terminal when the first event occurs, the network can know the specific vertical coordinates at which the first event occurred. This allows the network to recommend more suitable frequency points for subsequent UEs that pass through that vertical position and whose vertical position can be measured.

[0584] (2) Floor information of the terminal when the first event occurred;

[0585] In elevator scenarios, the UE mainly moves vertically. Based on the floor information of the terminal when the first event occurs, the network can know which floor the first event occurred on, and thus recommend a more suitable frequency priority for subsequent UEs that pass through that floor and whose vertical position can be measured.

[0586] (3) The last vertical height information of the terminal before the first event occurred;

[0587] (4) The last floor information of the terminal before the first event occurred;

[0588] (5) Vertical height information when the terminal enters the first transport vehicle;

[0589] In elevator scenarios, the UE mainly moves vertically. After entering the first means of transportation (elevator), the UE may be in a state of no coverage. Therefore, recording this information is helpful for marking the position information before entering the first means of transportation.

[0590] (6) Floor information when the terminal enters the first transport vehicle;

[0591] In elevator scenarios, the UE mainly moves vertically. After entering the first means of transportation (elevator), the UE may be in a state of no coverage. Therefore, recording this information is helpful for marking the position information before entering the first means of transportation.

[0592] (7) The distance the terminal travels within the first means of transport;

[0593] By combining the position before entering the first transport vehicle, the position where the terminal leaves the first transport vehicle can be calculated.

[0594] (8) The duration of the terminal's stay in the first means of transport;

[0595] Since the elevator's speed is relatively fixed, the position of the terminal after leaving the first transport vehicle can be calculated by combining the position before entering the first transport vehicle.

[0596] (9) Radio frequency identification information of the terminal’s last location before the first event occurred, such as multiple cell IDs and corresponding channel quality sets;

[0597] (10) The radio frequency fingerprint of the terminal when it enters the first means of transport, for example, multiple cell IDs and corresponding channel quality sets;

[0598] The radio frequency fingerprint of the terminal when it enters the first means of transport can indirectly represent the location information of the terminal when it enters the first means of transport.

[0599] (11) Radio frequency identification information of the terminal's location at the time of the first event, such as multiple cell IDs and corresponding channel quality sets;

[0600] The location information of the terminal at the time of the first event can be indirectly represented by the radio frequency identification information of the terminal at the time of the first event.

[0601] (12) The three-dimensional coordinates of the terminal when it enters the first transport vehicle;

[0602] (13) The three-dimensional coordinates of the first event.

[0603] In this embodiment, the identifier of the second scenario described above can be used to indicate at least one of the following:

[0604] The terminal is inside the first means of transport;

[0605] The terminal is outside the first means of transport;

[0606] The terminal enters the first means of transport;

[0607] The terminal leaves the first transport vehicle;

[0608] The terminal enters and leaves the first transport vehicle; for example, the terminal's last position before the first event occurs is outside the first transport vehicle, the terminal's position at the time of the first event occurs is inside the first transport vehicle, and the terminal's position after the first event occurs is outside the first transport vehicle.

[0609] The terminal passed by but did not enter the first transport vehicle.

[0610] The scenario in this application embodiment can be represented by a position sequence. This position sequence can be represented by at least two of positions 1, 2, and 3, wherein position 1 is used to indicate the last position of the terminal before the first event occurs; position 2 is used to indicate the position of the terminal when the first event occurs; and position 3 is used to indicate the position of the terminal after the first event occurs.

[0611] For example, if position 1 is located outside the first means of transport and position 2 is located inside the first means of transport, then it can be determined that the terminal has entered the first means of transport.

[0612] For example, if position 1 is located outside the first transport vehicle, position 2 is located inside the first transport vehicle, and position 3 is located inside the first transport vehicle, then it can be determined that the terminal has entered the first transport vehicle.

[0613] For example, if position 2 is located inside the first transport vehicle and position 3 is located outside the first transport vehicle, then it can be determined that the terminal has left the first transport vehicle.

[0614] For example, if position 1 is located inside the first transport vehicle, and positions 2 and 3 are located outside the first transport vehicle, then it can be determined that the terminal has left the first transport vehicle.

[0615] For example, if positions 1 and 2 are located inside the first transport vehicle and position 3 is located outside the first transport vehicle, then it can be determined that the terminal has left the first transport vehicle.

[0616] For example, if position 1 is located outside the first transport vehicle, position 2 is located inside the first transport vehicle, and position 3 is located outside the first transport vehicle, then it is determined that the terminal enters and leaves the first transport vehicle.

[0617] For example, if position 1 is located outside the first vehicle, position 2 is located outside the first vehicle, and position 3 is located outside the first vehicle, it can be determined that the terminal passed by but did not enter the first vehicle.

[0618] The scenarios in this application embodiment can be represented by a sequence of locations. For example, the first scenario, the second scenario, or the third scenario can be represented by the location sequence of the terminal.

[0619] For example, the location sequence {outside the first means of transport, inside the first means of transport} indicates that the terminal has entered the first means of transport.

[0620] For example, the location sequence {inside the first vehicle, outside the first vehicle} indicates that the terminal has left the first vehicle.

[0621] For example, the location sequence {outside the first vehicle, inside the first vehicle, outside the first vehicle} indicates that the terminal enters and leaves the first vehicle.

[0622] For example, the location sequence {outside the first vehicle, outside the first vehicle, outside the first vehicle} indicates that the terminal passed through but did not enter the first vehicle.

[0623] Example 1-2: Elevator Exit Scenario - Provision of Auxiliary Information;

[0624] Example 1-1 describes the recording and reporting process for the first event. Example 1-2 shows the network providing auxiliary information to subsequent UEs, thus preventing other UEs from failing to find suitable cells when passing through the same location. This allows for optimization of the UE's network search effectiveness based on the event. The corresponding signaling process is as follows: Figure 5 As shown, it includes:

[0625] Step 1: The UE receives first information sent by the first network-side device. The first information includes first configuration information, which includes frequency point priority information. The first information also includes at least one of the following:

[0626] The first scenario identification: For two different scenarios—whether the terminal is inside or outside the first mode of transport (e.g., an elevator)—the wireless propagation characteristics, such as signal penetration loss, differ significantly, making it impossible to apply the same frequency priority. If it can be determined whether the terminal is inside or outside the first mode of transport beforehand, it will be beneficial for the UE to obtain accurate frequency priority in step 3.

[0627] The first piece of information is location-related; different UE locations result in different frequency priorities. This location-related information helps the UE determine a more suitable frequency priority in step 3.

[0628] The first service identifier helps the UE choose whether to change the frequency priority based on a specific service. If the UE's current service is highly sensitive to channel quality and requires rapid restoration of radio quality, then special scenario identification and location measurement are needed in step 2, and the corresponding frequency priority is obtained based on the first information. If the current service is not sensitive to channel quality, steps 2 and 3 can be omitted.

[0629] The first event identifier; this identifier helps to inform the UE which wireless quality deterioration or failure events are likely to occur at the corresponding location in the historical time.

[0630] The associated identifier of the service community;

[0631] Association identifiers between adjacent communities.

[0632] In this embodiment of the application, when providing the UE's location based on radio frequency fingerprint, the channel quality information measured by the UE is related to the antenna or beam configuration of the network device. If the antenna configuration or beam configuration of the network device changes, the channel quality of multiple cells measured by the UE will also change. The association ID of the serving cell or the association ID of the neighboring cells is beneficial to the consistency between the data characteristics of the auxiliary information provided subsequently and the data characteristics of the radio frequency identification information.

[0633] The first information includes multiple frequency point priority information. The frequency point priority information is associated with at least one of the following:

[0634] Information related to the first position;

[0635] The first scene identifier.

[0636] The first piece of information mentioned above can also be described as frequency point map information.

[0637] The first position-related information is associated with frequency priority information and includes at least one of the following:

[0638] First height information, the first height information includes the vertical height information of the terminal;

[0639] Second height information, which includes the floor information where the terminal is located;

[0640] The first location information includes vertical height information when the terminal enters the first transport vehicle, or, described as vertical height information of the initial location;

[0641] The second location information includes floor information when the terminal enters the first transport vehicle, or floor information described as the initial location;

[0642] The third location information includes the vertical height information when the terminal leaves the first transport vehicle;

[0643] The fourth location information includes the floor information when the terminal leaves the first means of transport;

[0644] The first distance includes the distance the terminal travels within the first means of transport;

[0645] The first duration includes the duration of the terminal's stay within the first means of transport;

[0646] First radio frequency identification information, the first radio frequency identification information includes radio frequency identification information when the terminal enters the first means of transport;

[0647] The second radio frequency identification information includes the radio frequency identification information of the location of the terminal;

[0648] The first coordinate information includes the coordinate information when the terminal enters the first means of transport;

[0649] The second coordinate information includes the coordinates of the terminal's location.

[0650] Step 2: The UE measures and obtains information related to the third location, and can also measure and identify the third scene.

[0651] The information related to the third position includes at least one of the following:

[0652] Vertical height information of the terminal when it leaves the first transport vehicle;

[0653] Floor information when the terminal leaves the first mode of transport;

[0654] Vertical height information when the terminal enters the first transport vehicle;

[0655] Floor information when the terminal enters the first transport vehicle;

[0656] The distance the terminal travels within the first means of transport;

[0657] The duration of the terminal's stay within the first means of transport;

[0658] Radio frequency identification information of the terminal when it enters the first means of transport, such as multiple cell IDs and corresponding channel quality sets;

[0659] The terminal's radio frequency identification information at the time of the first event, such as multiple cell IDs and corresponding channel quality sets;

[0660] The three-dimensional coordinates of the terminal when it enters the first transport vehicle;

[0661] The three-dimensional coordinates of the terminal when the first event occurs.

[0662] Step 3: The UE determines the frequency priority list based on the third location information or based on the third location information and the third scenario.

[0663] Specifically, the UE determines whether the terminal location corresponding to the third location-related information matches the terminal location corresponding to the first location-related information in the first information. If they match, the UE can determine the frequency priority information associated with the third location-related information based on the frequency priority information associated with the first location-related information.

[0664] or,

[0665] In addition to determining whether the terminal location corresponding to the third location-related information matches the terminal location corresponding to the first location-related information, the terminal also determines whether the identifier of the third scenario matches the identifier of the first scenario. If the identifiers of the two scenarios match, and the two terminal locations also match, the frequency priority information associated with the third location information is determined based on the frequency priority information associated with the first location-related information.

[0666] Example 2: An example of frequency priority information (frequency priority list) in the first information;

[0667] Examples 1-2 show how the network provides auxiliary information to subsequent UEs. This example 2 is a specific example of frequency priority information included in the fourth information, which enables the UE to determine the corresponding frequency priority list in step 3 of examples 1-2 based on its location, or based on its location and a special scenario.

[0668] Example 2-1: Frequency priority list: associated with absolute location information;

[0669] Table 2: Example of frequency priority information (associated with the location of the UE leaving a special scenario)

[0670]

[0671]

[0672] As shown in Table 2, the first information contains multiple frequency point priorities. The UE can obtain the location (e.g., vertical height information or floor information) by measurement to obtain the corresponding frequency point priority.

[0673] Example 2-2: Frequency priority list: associated with initial position + distance information;

[0674] Table 3a: Example of frequency priority information (associated with the position of entering the special container and the distance through the special container);

[0675]

[0676] As shown in Table 3a, the first information includes multiple frequency priority levels. Each frequency priority level is related to the UE's entry point into the special container and the distance it moves within the special container. The UE can determine the corresponding frequency priority by measuring its entry point into the special container and the distance it moves within the special container.

[0677] Table 3b: Example of frequency priority information (associated with the position of entering the special container and the distance through the special container);

[0678]

[0679] As shown in Table 3b, the first information includes multiple frequency priority levels. Each frequency priority is related to the UE's entry point into the special container and the distance it moves within the special container. The UE can determine the corresponding frequency priority by measuring its entry point into the special container and the distance it moves within the special container.

[0680] Table 4: Example of frequency priority information (associated with the position entering the special container and the distance through the special container)

[0681]

[0682] As shown in Table 4, the first information includes multiple frequency priority points. Each frequency priority point is related to the floor F from which the UE enters the special container and the distance d2 it moves within the special container. The UE can determine the corresponding frequency priority point by measuring the position F from which it enters the special container and the distance d2 it moves within the special container.

[0683] Example 2-3: Frequency priority list: associated with wireless RF fingerprint + associated ID + associated by distance;

[0684] For a scheme that determines the UE location based on radio frequency fingerprinting, when the UE determines the third location-related information, in addition to obtaining the serving cell ID, neighboring cell ID, channel quality of the serving cell, and service quality of the neighboring cells, it also needs to obtain the association ID of the serving cell and the neighboring cells.

[0685] Table 5-1: Frequency priority information list (with radio frequency fingerprint + associated ID + distance association) when cell 1's associated ID2 = 4, cell 2's associated ID2 = 2, and cell 3's associated ID2 = 1.

[0686]

[0687] As shown in Table 5-1, the first information includes multiple frequency priority levels. Each frequency priority is related to the UE's radio frequency fingerprint upon entering the special container, the associated ID of the relevant cell, and the movement distance d2 within the special container. The UE can determine the corresponding frequency priority by measuring the radio frequency fingerprint upon entering the special container, the movement distance d2 within the special container, and the associated ID of the relevant cell based on the radio frequency fingerprint.

[0688] Table 5-2: When the associated ID2 of cell 1 is 3, the associated ID2 of cell 2 is 2, and the associated ID2 of cell 3 is 1, the frequency priority information list (associated with radio frequency fingerprint + associated ID + distance);

[0689]

[0690] The cell association IDs in Tables 5-1 and 5-2 are different. Therefore, it is necessary to determine the corresponding frequency priority list based on the cell association ID.

[0691] Example 2-4: Frequency priority list: associated with initial position + distance information + scene ID;

[0692] Table 6 Frequency Point Priority Information List (Associated with Initial Position + Distance Traveled + Scene ID)

[0693]

[0694] As shown in Table 6, the first information includes multiple frequency point priorities. Each frequency point priority is related to the UE's position when entering the special container, the distance it moves within the special container, and the special scenario. Among them, the special scenario includes the special scenario of the initial position and the special scenario corresponding to the frequency point priority.

[0695] The UE can determine the corresponding frequency priority according to Table 6 by measuring the initial position, the special scenario corresponding to the initial position, the movement distance within the special container, and the special scenario corresponding to the movement after d2.

[0696] By taking different values ​​for the scene at the initial position and the scene after passing through d2, a variety of special scenes can be created:

[0697] For example:

[0698] Entering the elevator scene: The scene at the initial position = outside the special container, and the scene after passing d2 = inside the special container;

[0699] Elevator scene: The scene at the initial position = inside a special container, and the scene after d2 = inside a special container;

[0700] Exiting the elevator scene: The scene at the initial position = outside the special container, the scene after passing d2 = outside the special container, or

[0701] The scene at the initial position is inside the special container, and the scene after d2 is outside the special container.

[0702] Example 3: Detailed process analysis of the entire elevator ride;

[0703] Assume the state of the terminal before and after entering the elevator is as shown in Table 7;

[0704] Table 7

[0705]

[0706] Example 1 introduces the key steps. This example describes in detail the process of cell reselection / cell selection / cell handover based on the proposed frequency point list when taking an elevator.

[0707] Embodiment 3-1 of the present invention: Case 1: As shown in Table 8, the user is in an idle state before entering the elevator, and after entering the elevator, the OSS (out-of-service, no coverage, or no service) is active. Figure 3 As shown, when exiting the elevator, the passenger stopped at point 2 in the residential area.

[0708] Table 8

[0709]

[0710] The corresponding signaling process, such as Figure 6 The following are included:

[0711] Step 1: The UE receives first information sent by a first network-side device. The first information includes first configuration information, which includes frequency priority information and may also include at least one set of S-criteria parameters. This first configuration information is associated with at least one of the identifier of a first scenario and first location-related information.

[0712] Among them, the parameters of a set of S criteria are associated with at least one of the identifier of the first scene and the first location-related information.

[0713] The parameters of at least one set of the above S criteria can be carried in the broadcast signal or the RRC dedicated signaling, such as the broadcast signal being SIB1, and the RRC dedicated signaling being the RRC reconfiguration signaling or the RRC release signaling.

[0714] One set of S-criterion parameters includes at least one of the following:

[0715] The temporary offset Qoffsettemp of the cell, which is a temporary offset applied to this cell;

[0716] Minimum received level Q in the cell rxlevmin For example, the minimum receive RSRP required by the cell;

[0717] The bias Q of the lowest received level in the cell rxlevminoffset ;

[0718] Penalty value for UEs that do not reach the cell's maximum power;

[0719] Minimum received signal quality Q in the cell qualmin For example, the minimum receive RSRQ required by the cell;

[0720] The minimum received signal quality offset Q of the cell qualminoffset .

[0721] Step 2 (optional): Inside the elevator, the UE measures and acquires information related to the third location, and can also measure and identify the third scene.

[0722] The UE can skip network search to save power when one of the following conditions is met.

[0723] The first location-related information associated with the frequency priority information does not include the third location-related information.

[0724] The frequency priority information corresponding to the third location-related information is an empty set;

[0725] The first scenario associated with the frequency priority information does not include the third scenario;

[0726] The frequency priority information corresponding to the third scenario is an empty set.

[0727] As shown in Table 9, when the UE's third location information is the second floor and the third scenario is inside the elevator, the terminal can skip network search to save power.

[0728] Table 9

[0729] Information related to the third location (inside the elevator) Frequency priority 1 1st floor f1,f2,f3 2 2nd floor 3 3rd floor f2,f1,f3

[0730] Step 3: When exiting the elevator, the UE measures and obtains information related to the third location, and can also measure and identify the third scene.

[0731] For example, the third scenario is determined to be: currently inside a special container, about to leave the special container. The relevant information for the third location is determined to be the first floor.

[0732] Alternatively, determine the third scenario as: leaving the special container. Determine the relevant information for the third location as the first floor.

[0733] Step 4: The UE determines the frequency priority list based on the third location information and the third scenario. Cell measurement is then performed based on the frequency priority list.

[0734] Since the UE is currently in a no-service state, it can select a suitable cell using the S criterion.

[0735] Optionally, when the UE receives at least one set of S-criteria parameters, it can perform cell selection based on the S-criteria parameters associated with the third location-related information (defined as the first cell selection parameters), or based on the S-criteria parameters associated with the third location-related information and the third scenario (defined as the first cell selection parameters).

[0736] Optionally, the first cell selection parameters can have a shorter timer observation duration and / or a lower threshold, allowing the UE to camp on cell 2 more quickly.

[0737] Example 3-2: Case 2: As shown in Table 10, the user is in a connected state before entering the elevator, OOS after entering the elevator, and connected to community 2 when exiting the elevator;

[0739]

[0740] For the corresponding signaling flow, please refer to [reference needed]. Figure 6 ,include:

[0741] Step 1: The UE obtains first information from a first network-side device. The first information includes first configuration information, which includes frequency priority information and may also include at least one set of S-criteria parameters. This first information is associated with at least one of the identifier of a first scenario and first location-related information.

[0742] The aforementioned first information can be carried in RRC dedicated signaling, such as RRC reconfiguration or RRC release messages, or in broadcast signals, such as SIB1.

[0743] Step 2 (optional): Same as step 2 in Example 3-1.

[0744] Step 3: Same as step 3 in Example 3-1.

[0745] Step 4: The UE determines the frequency priority list based on the third location information and the third scenario. Cell measurement is then performed based on the frequency priority list.

[0746] Since the UE is currently in a no-service state, it can select a suitable cell using the S criterion (e.g., ...). Figure 3 (Community 2 in the middle).

[0747] Optionally, when the UE receives at least one set of S-criteria parameters, it can perform cell selection based on the S-criteria parameters associated with the third location-related information (defined as the first cell selection parameters), or based on the S-criteria parameters associated with the third location-related information and the third scenario (defined as the first cell selection parameters).

[0748] Optionally, the first cell selection parameters can have a shorter timer observation duration and / or a lower threshold, allowing the UE to camp on cell 2 more quickly.

[0749] Then, to the appropriate community where they reside (such as...) Figure 3 In cell 2), a random access is initiated, and the cell enters the connected state.

[0750] Example 3-3: Case 3: As shown in Table 11 and Figure 7 As shown, the user is in an idle state before entering the elevator, stays in community 3 after entering the elevator, and stays in community 2 when exiting the elevator.

[0751] Table 11

[0752]

[0753]

[0754] like Figure 8 As shown, the corresponding signaling flow is as follows:

[0755] Step 1: The UE receives first information sent by a first network-side device. The first information includes first configuration information, which includes frequency priority information and may also include at least one set of cell reselection parameters and / or at least one set of cell selection parameters (e.g., S-criteria). This first configuration information is associated with at least one of the identifier of a first scenario and first location-related information.

[0756] One set of parameters for cell reselection is associated with at least one of the identifier of the first scenario and information related to the first location.

[0757] One of the parameters for a cell reselection includes at least one of the following:

[0758] Same-frequency measurement start threshold, for example, S IntraSearchP and S IntraSearchQ ;

[0759] Inter-frequency / inter-system measurement start threshold, for example, S nonIntraSearchP and S nonIntraSearchQ ;

[0760] The value of the cell reselection timer, for example, TreselectionRAT;

[0761] Signal strength threshold for cell reselection, for example, Thresh. X,HighP ;

[0762] Signal quality thresholds for cell reselection, for example, Thresh. X,HighQ ;

[0763] The threshold for the duration the UE resides in the source cell;

[0764] A set of S-criterion parameters are associated with at least one of the identifier of the first scene and the first location-related information.

[0765] The parameters of at least one set of the above S criteria can be carried in the broadcast signal or the RRC dedicated signaling, such as the broadcast signal being SIB1, and the RRC dedicated signaling being the RRC reconfiguration signaling or the RRC release signaling.

[0766] One set of S-criterion parameters includes at least one of the following:

[0767] The temporary offset Qoffsettemp of the cell, which is a temporary offset applied to this cell;

[0768] Minimum received level Q in the cell rxlevmin For example, the minimum receive RSRP required by the cell;

[0769] The bias Q of the lowest received level in the cell rxlevminoffset ;

[0770] Penalty value for UEs that do not reach the cell's maximum power;

[0771] Minimum received signal quality Q in the cell qualmin For example, the minimum receive RSRQ required by the cell;

[0772] The minimum received signal quality offset Q of the cell qualminoffset .

[0773] The aforementioned first information can be carried in a broadcast signal or RRC dedicated signaling, such as SIB1 for the broadcast signal and RRC dedicated signaling for RRC reconfiguration signaling or RRC release signaling.

[0774] In one embodiment, by using cell reselection parameters associated with at least one of the identifier of the first scenario and the first location-related information, the timer value can be set to be shorter and the measurement start threshold can be set to be lower, so that the UE can reselect the cell corresponding to the high priority frequency point corresponding to the third location-related information more quickly during cell reselection in step 5.

[0775] Step 2 (optional): The terminal camps on cell 3.

[0776] Scenario 1: Cell 3 is a 2G / 3G cell. Based on the third location information and frequency priority information, cell 3 is determined to be a high-priority frequency. The UE measures and reselects cell 3.

[0777] Scenario 2: Cell 3 is a 2G / 3G cell. The high-priority frequency search range is determined based on the location information and frequency priority information of Cell 3. The high-priority frequency search range is the same as or adjacent to the RAT of Cell 1.

[0778] For example, when cell 1 is 5G, the high-priority frequency search range can include the following RAT: 4G, 5G, 6G;

[0779] For example, when cell 1 is 4G, the high-priority frequency search range can include the following RAT: 4G, 5G;

[0780] When the search range of high-priority frequency points does not include suitable cells, it is possible to skip searching for cells in the same or adjacent RATs and directly search for cells in a more distant RAT (e.g., 2G / 3G).

[0781] Table 12

[0782]

[0783] By using frequency priority information, the network search time for cells with the same RAT and adjacent RATs can be reduced. When the search range of high-priority frequencies does not meet the cell reselection rules, a 2G / 3G network search can be performed quickly.

[0784] Case 3 (Method 1 in Table 12): First search for 5G and 4G, but find no suitable cells. Blind search reveals that the 2 / 3G frequency signal is the best, so stay on 2 / 3G.

[0785] Scenario 4: Cell 3 is a 4G / 5G cell. Based on the relevant information of the third location and the frequency priority information, it is determined that cell 3 is a high-priority frequency.

[0786] Step 3 (optional): The UE measures and obtains information related to the third location, and can also measure and identify the third scene.

[0787] For example, the third scenario is: currently inside a special container, about to leave the special container. The relevant information for the third location is determined to be the first floor.

[0788] Alternatively, the third scenario is: leaving the special container. The relevant information for the third location is confirmed to be the first floor.

[0789] (Same as Example 3-1)

[0790] Step 4 (optional): The UE determines the frequency priority list based on the third location information and the third scenario. Cell measurement is then performed based on the frequency priority list.

[0791] Step 5: Stay in Community 2.

[0792] Scenario A: When step 2 is scenario 1-3, cell 3 is a 2G / 3G cell. At this time, the UE is in the 2G / 3G idle state, but not in the 5G idle state, and is in the network search phase. Therefore, a suitable cell will be selected according to the S criterion.

[0793] Optionally, when the UE receives at least one set of S-criteria parameters, the UE measures and obtains third location-related information, and can also measure and identify a third scenario (same as step 3), and then performs cell selection based on the S-criteria parameters associated with the third location-related information (defined as first cell selection parameters), or based on the S-criteria parameters associated with the third location-related information and the third scenario (defined as first cell selection parameters).

[0794] Specifically, by selecting parameters for the first cell, the UE can be made to stay in cell 2 more quickly when exiting the elevator.

[0795] Scenario B: When step 2 is scenario 4, cell 3 is a 4G / 5G cell. In this case, the UE is in the 5G idle state. Therefore, it will be reselected to camp on a suitable cell.

[0796] Optionally, when the UE receives at least one set of cell reselection parameters, it can perform cell reselection based on the cell reselection parameters associated with the third location-related information (defined as the first cell reselection parameters), or the cell reselection parameters associated with the third location-related information and the third scenario (defined as the first cell reselection parameters).

[0797] Specifically, by adjusting the first cell reselection parameters, the UE can be more quickly camped on cell 2 when exiting the elevator. Examples 3-4: Case 4: As shown in Table 13 and... Figure 7 As shown, the user is in a connected state before entering the elevator, connects to community 3 after entering the elevator, and connects to community 2 when exiting the elevator.

[0798] Table 13

[0799]

[0800] like Figure 9 As shown, the corresponding signaling flow is as follows:

[0801] Step 1: The UE receives first information sent by a first network-side device. The first information includes first configuration information, which includes frequency priority information and may also include at least one set of cell handover parameters and / or at least one set of cell selection (S-criteria) parameters. This first configuration information is associated with at least one of the identifier of a first scenario and first location-related information.

[0802] One set of cell handover parameters is associated with at least one of the identifier of the first scenario and the first location-related information.

[0803] One set of parameters for cell handover includes at least one of the following:

[0804] Neighboring cell measurement object-specific offset, such as Ofn;

[0805] Neighboring cell-specific offset, such as Ocn;

[0806] Event hysteresis, such as Hys;

[0807] The serving cell measurement object-specific offset, for example, Ofp;

[0808] Serving cell specific offset, for example, Ocp;

[0809] A3 event offset, for example, Off;

[0810] Event timers, such as TimeToTrigger.

[0811] A set of S-criterion parameters are associated with at least one of the identifier of the first scene and the first location-related information.

[0812] The parameters of at least one set of the above S criteria can be carried in the broadcast signal or the RRC dedicated signaling, such as the broadcast signal being SIB1, and the RRC dedicated signaling being the RRC reconfiguration signaling or the RRC release signaling.

[0813] One set of S-criterion parameters includes at least one of the following:

[0814] The temporary offset Qoffsettemp of the cell, which is a temporary offset applied to this cell;

[0815] Minimum received level Q in the cell rxlevmin For example, the minimum receive RSRP required by the cell;

[0816] The bias Q of the lowest received level in the cell rxlevminoffset ;

[0817] Penalty value for UEs that do not reach the cell's maximum power;

[0818] Minimum received signal quality Q in the cell qualmin For example, the minimum receive RSRQ required by the cell;

[0819] The minimum received signal quality offset Q of the cell qualminoffset .

[0820] The aforementioned first information can be carried in a broadcast signal or RRC dedicated signaling, such as SIB1 for the broadcast signal and RRC dedicated signaling for RRC reconfiguration signaling or RRC release signaling.

[0821] In one embodiment, by using cell handover parameters associated with at least one of the identifier of the first scenario and the first location-related information, the timer value can be set to be shorter and the measurement start threshold can be set to be lower, so that the UE can reselect the cell corresponding to the high priority frequency point corresponding to the third location-related information more quickly during cell handover in step 5.

[0822] Step 2 (optional): The terminal connects to cell 3.

[0823] Scenario 1: Cell 3 is a 2G / 3G cell. Based on the third location information and frequency priority information, cell 3 is determined to be a high-priority frequency. The UE measures and switches to cell 3.

[0824] Scenario 2: Cell 3 is a 2G / 3G cell. The high-priority frequency search range is determined based on the location information and frequency priority information of Cell 3. The high-priority frequency search range is the same as or adjacent to the RAT of Cell 1.

[0825] For example, when cell 1 is 5G, the high-priority frequency search range can include the following RAT: 4G, 5G, 6G;

[0826] For example, when cell 1 is 4G, the high-priority frequency search range can include the following RAT: 4G, 5G;

[0827] When the search range of high-priority frequency points does not include a suitable cell, a Radio Link Failure (RLF) occurs, and the connection changes from connected to disconnected. The system then blindly searches for 2G / 3G networks, camps on cell 3, and then randomly connects to cell 3 to continue the call.

[0828] Table 14

[0829]

[0830] By using frequency priority information, the measurement time for cells with the same RAT (Range Attribution) and adjacent RATs can be reduced. When the search range of high-priority frequencies does not meet the requirements for a cell handover event, a direct RLF (Random Access Request) can be initiated to quickly search for 2G / 3G networks.

[0831] Scenario 3 (Method 1 in Table 14): No suitable cell can be found in either 5G or 4G, resulting in an RLF (Linked Low Frequency) event, transitioning from a connected to a disconnected state. A blind search reveals the best signal on 2G / 3G frequencies, so the user camps on cell 3 and then randomly connects to cell 3 to continue the call.

[0832] Scenario 4: Cell 3 is a 4G / 5G cell. Based on the third location-related information and frequency priority information, cell 3 is determined to be a high-priority frequency, and the handover is initiated to cell 3. Optionally, in this case, if step 1 obtained cell handover parameters associated with at least one of the identifier of the first scenario and the first location-related information (defined as the first cell handover parameters), then the first cell handover parameters can be used to quickly hand over to cell 3.

[0833] Scenario 5: Cell 3 is a 4 / 5G cell. After the elevator door closes, the signal suddenly weakens, and before the A2 event is reported, an RLF (Remote Link Default) occurs, entering a connectionless state. Based on the third location information and frequency priority information, cell 3 is determined to be a high-priority frequency. Measurements are taken in cell 3, the system camps on cell 3, and randomly connects to cell 3.

[0834] Scenario 6: Cell 3 is a 4G / 5G cell. After the elevator door closes, the signal suddenly weakens before the A2 event is reported. An RLF (Reconnection-Free Response) occurs, and the cell enters a connectionless state. By measuring multiple frequency points, the cell selector chooses cell 3, camps on cell 3, and randomly connects to cell 3. (Compared to Scenario 5, Scenario 6 does not utilize third-party location information and frequency priority information; therefore, it requires measuring multiple frequency points to find a suitable cell to camp on and connect to. The latency to enter cell 3 will be longer.)

[0835] Step 3 (optional): The UE measures and obtains information related to the third location, and can also measure and identify the third scenario. The second special scenario is determined to be: currently inside a special container, about to leave the special container. The second location is determined to be the first floor.

[0836] or,

[0837] The second special scenario is determined to be: leaving the special container. The second location is determined to be the first floor.

[0838] (Same as Example 3-1)

[0839] Step 4 (optional): The UE determines the frequency priority list based on the third location information and the third scenario. Cell measurement is then performed based on the frequency priority list.

[0840] Step 5: Connect to Cell 2.

[0841] Scenario A: When step 2 is scenario 1-3, cell 3 is a 2G / 3G cell. At this time, the UE is in a 2G / 3G connected state, but not in a 5G connected state; instead, it is in the 5G network search phase. After the UE exits the elevator, an RLF occurs in 2G / 3G, changing from a connected state to a disconnected state. Afterward, the UE measures and obtains third location-related information, and can also measure and identify a third scenario (same as step 3). Then, based on the third location-related information and frequency priority information, it determines the priority frequency (same as step 4). Through measurement, it camps on cell 2 through cell selection (e.g., S criterion) and then randomly accesses and connects to cell 2 (4G / 5G).

[0842] Optionally, when the UE receives the parameters of the S criterion, it can perform cell selection based on the parameters of the S criterion associated with the third location-related information (defined as the first cell selection parameters), or the parameters of the S criterion associated with the third location-related information and the third scenario (defined as the first cell selection parameters).

[0843] Specifically, by selecting parameters for the first cell, the UE can be made to stay in cell 2 more quickly when exiting the elevator.

[0844] Scenario B: When step 2 corresponds to scenarios 4-6, cell 3 is a 4G / 5G cell. In this case, the UE is in 4G / 5G connected state. Therefore, it will switch to a suitable cell through cell handover.

[0845] Optionally, when the UE receives the cell handover parameters, it can perform cell handover based on the parameters of the S criterion associated with the third location-related information (defined as the first cell reselection parameters), or the cell handover parameters associated with the third location-related information and the third scenario (defined as the first cell handover parameters).

[0846] Specifically, by using the first cell handover parameters, the UE can be switched to cell 2 more quickly when exiting the elevator.

[0847] In this embodiment of the application, the frequency priority information, cell selection information, cell reselection information and cell handover information in the first information can be sent by one signaling message or by multiple signaling messages.

[0848] The above-described solution in this application provides a method for indicating frequency priority based on UE location and special scenarios, thereby avoiding the problem of frequency priority list failure caused by UE movement and service failure. Furthermore, when more than one frequency priority configuration can be obtained in a cell, the UE can determine the corresponding frequency priority at different locations.

[0849] The above-described solutions in this application provide a method for indicating cell selection information, and / or cell reselection information, and / or cell handover information based on UE location and special scenarios. This avoids mobility management failures caused by signal abrupt changes in special container-related scenarios where the UE is located. More than one cell selection configuration, and / or cell reselection configuration, and / or cell handover configuration can be obtained within a single cell, allowing the UE to determine corresponding cell selection parameters, and / or cell reselection parameters, and / or cell handover parameters at different locations.

[0850] like Figure 10 As shown in the figure, this application embodiment also provides an information transmission method, the method comprising:

[0851] Step 1001: The first network-side device sends at least one of the first information and the second information to the terminal;

[0852] The first information includes first configuration information, and at least one of the identifier of a first scenario associated with the first configuration information and first location-related information. The first configuration information includes at least one of frequency priority information, cell selection information, cell reselection information and cell handover information.

[0860] In this embodiment, a first network-side device sends first information to a terminal, enabling the terminal to obtain frequency priority information, cell selection information, cell reselection information, or cell handover information associated with a first scenario and / or first location information provided by the network-side device. The terminal can then perform mobility management based on this information. Alternatively, the first network-side device sends second information to the terminal, enabling it to collect a first report related to the aforementioned first event. Since the first event is associated with at least one of a second scenario and second location information, the network-side device can determine the second scenario and / or second location information of the terminal where the first event occurred based on the first report. Therefore, the network-side device can provide appropriate frequency priority information, cell selection information, cell reselection information, or cell handover information to the terminal in the second scenario and / or second location, thereby improving the communication performance of the terminal in different scenarios.
