Communication systems typically support cell selection procedures for terminal devices.

When a user who needs to use the network service moves from one cell to another, or due to reasons such as wireless transmission business load adjustment, activation operation maintenance, equipment failure, etc., in order to ensure the continuity of communication and the quality of service, the system will The communication link with the original cell is transferred to the new cell, that is, the cell switching process is performed. Thus, a terminal device device can be handed over from the cell of the first network device to the cell of the second network device.

Fig. 2 shows a flowchart of a cell selection method provided by an exemplary embodiment of the present application. In this embodiment, this method is applied to terminal equipment. The method includes:

Step 201: The terminal device performs cell selection or cell reselection according to model-related information of application models supported by at least one cell.

The model identification information of the application model refers to the identification information used to uniquely identify the application model; the priority information corresponding to the application model refers to the priority information of the application model, and the priority information of the same application model in different terminal devices may be different ; The accuracy level information corresponding to the application model refers to the operation accuracy information of different application models.

Exemplarily, when the terminal device is turned on or enters the coverage area from a blind area, it searches for a frequency point allowed by a Public Land Mobile Network (PLMN), and selects a suitable cell in at least one cell to camp on.

Fig. 3 shows a flowchart of a cell selection method provided by an exemplary embodiment of the present application. In this embodiment, this method is applied to terminal equipment. The method includes:

Step 301: The terminal device determines a target model identification set.

Exemplarily, the target model identification set refers to a set of identification information of application models expected to be obtained by the terminal device, and the target model identification set includes identification information of at least one application model.

Optionally, the target model identification set determined by the terminal device may pass through the non-access stratum (Non-Access Stratum, NAS) of the terminal device, or, through the access stratum (Access Stratum, AS) of the terminal device or, through the network device The configuration process is obtained, which is not limited in this application.

Step 302: The terminal device selects a cell according to the model identification information of the application models supported by the cell and the target model identification set.

The model identification information of the application model refers to identification information for uniquely identifying the application model.

Exemplarily, the terminal device judges according to the model identification information of the application model supported by the cell and the target model identification set, and if the terminal device finds a target cell, the terminal device selects the target cell to camp on.

The method for the terminal device to select a cell according to the model identification information of the application model supported by the cell and the target model identification set includes at least one of the following four methods:

Method 1: Determine at least one cell with the largest number of elements intersecting with the target model ID set among the model ID sets supported by the searched cells as a candidate cell, and determine the target cell among the candidate cells according to the S criterion.

Exemplarily, the target cell refers to a cell where the terminal device can camp on among the cells searched by the terminal device.

The terminal device determines the set of target model identifiers and the set of application model identifiers supported by the cell searched by the terminal device, and compares and judges at least one of the set of model identifiers supported by the searched cell that has the largest number of elements intersecting with the target model identifier set The cell serves as a candidate cell, and within the range of the candidate cell, the terminal device determines the target cell according to the S criterion.

Within the range of candidate cells, if the cell satisfies the S criterion, the cell is considered to be a suitable cell, and the cell is selected as the target cell to reside in; if the cell does not meet the S criterion, continue to judge the next candidate cell , until a candidate cell satisfies the S criterion.

If all candidate cells within the range of candidate cells do not satisfy the S criterion, cell selection is performed among the cells searched by the terminal device. In the range of cells searched by the terminal device, the terminal device determines the target cell according to the S criterion, and selects the cell to reside.

The technical solutions provided by the embodiments of the present application can be applied to the NTN system, and can also be applied to the cellular network system.

The S criterion refers to a basic condition for a terminal device to normally reside in a cell, and means that the cell can provide a service level that meets the S criterion. That is to say, only when the measurement and evaluation results of a cell meet the S criterion, the May become the target cell for cell selection.

The S Guidelines state that:

Srxlev>0 and Squal>0

Among them, Srxlev is the received power in the cell search; Squal is the signal quality received in the cell search; the expressions of Srxlev and Squal are as follows:

Srxlev=Qrxlevmeas-(Qrxlevmin+Qrxlevminoffset)-Pcompensation-Qoffsettemp

Squal＝Qqualmeas-(Qqualmin+Qqualminoffset)-Qoffsettemp

The meaning of each parameter appearing in the above expression is explained as follows:

Qrxlevmeas is the reference signal receiving power (Reference Signal Receiving Power, RSRP) calculated by the actual measurement of the terminal equipment.

Qqualmeas is the reference signal receiving quality (Reference Signal Receiving Quality, RSRQ) obtained by the actual measurement and calculation of the terminal equipment.

Qrxlevmin is the minimum received power RSRP required by the network equipment.

Qqualmin is the minimum signal quality RSRQ required by network equipment.

Qrxlevminoffset and Qqualminoffset are offsets to prevent the ping-pong effect between two Public Land Mobile Networks (PLMN) due to radio environment fluctuations, that is to say, Qrxlevminoffset and Qqualminoffset are respectively The offsets to Qrxlevmin and Qqualmin that need to be considered when periodically searching for higher priority PLMNs on the Land Mobile Network (Visited Public Land Mobile Network, VPLMN).

Pcompensation is power compensation, for example, when the maximum transmission power allowed by the network equipment is greater than the maximum uplink transmission power determined by the terminal equipment's own capability, the power compensation is caused by the low power of the terminal equipment.

Qoffsettemp is only used for special scenarios, not for normal situations, such as the "Chiba problem" scenario.

Since RSRP indicates the received power of the reference signal, Qrxlevmeas-(Qrxlevmin+Qrxlevminoffset) indicates the quality of the downlink received signal, and Pcompensation indicates the quality of the uplink transmitted signal, therefore, relative to RSRP, Srxlev is evaluated by comprehensively considering the power strength of the uplink and downlink signals, and can be expressed The evaluation value of the service quality that the cell can provide. RSRQ, as a signal quality measurement value that takes RSRP and total received power (including interference and noise effects) into consideration, can provide a more reliable evaluation basis than RSRP, so Squal also indicates the service level of a cell. Srxlev and Squal can comprehensively evaluate the quality of service that the cell can provide. Therefore, the S criterion becomes the basic evaluation condition for whether a cell can camp.

In a possible implementation, when the terminal device selects a cell, it measures the Qrxlevmeas value and Qqualmeas of the searched cell, obtains other parameters in the S criterion formula through the system information of the cell and its own capability level, and calculates Srxlev and Squal, and then compare it with 0. If Srxlev>0 and Squal>0, that is, the cell satisfies the S criterion, the terminal device considers that the cell meets the signal quality requirements for cell selection, and can select it as the cell to reside on. If the cell's system information broadcasts that it is allowed to camp on, then the terminal will choose to camp on this cell.

For example, as shown in Figure 4, the terminal device determines the target model ID set, the terminal device searches for cell A and cell B, the model ID set supported by cell A found by the terminal device includes AI model ID 1, and the cell A and B found by the terminal device include AI model ID 1. The model ID set supported by B includes AI model ID 2, AI model ID 3, and AI model ID 4. Through comparison and judgment, the number of intersection elements between cell B and the target model ID set is the largest, so cell B is taken as a candidate cell, and according to S The criteria determine whether cell B can camp on as a target cell.

Method 2: Determine at least one cell whose number of intersection elements in the model identification set supported by the searched cell meets the first threshold with the target model identification set as a candidate cell, and determine the target cell among the candidate cells according to the S criterion.

Exemplarily, the first threshold is a default value or configured through a network device.

The terminal device determines the model identification set supported by the cell in the searched cell, and by comparing with the target model identification set determined by the terminal device, the number of intersection elements in the model identification set supported by the cell and the target model identification set satisfies the first In the case of the threshold value, the cell is determined to be a candidate cell, and within the range of the candidate cell, the terminal device determines the target cell according to the S criterion.

For example, as shown in Figure 4, the terminal device determines the target model ID set, the terminal device searches for cell A and cell B, the model ID set supported by cell A found by the terminal device includes AI model ID 1, and the cell A and B found by the terminal device include AI model ID 1. The model ID set supported by B includes AI model ID 2, AI model ID 3, and AI model ID 4. Through comparison and judgment, the number of intersection elements between cell B and the target model ID set satisfies the preset first threshold 2, so the cell B is used as a candidate cell, and judges whether cell B can be used as a target cell to camp on according to the S criterion.

Mode 3: Select the first application model ID with the highest priority in the target model ID set, determine at least one cell that supports the first application model ID as a candidate cell, and determine the target cell among the candidate cells according to the S criterion.

Optionally, the priority of the application model identifier in the target model identifier set determined by the terminal device may be provided by the NAS of the terminal device, or determined based on the implementation of the AS of the terminal device, or obtained by the terminal device from the network device configuration process, this Applications are not limited to this.

Exemplarily, the first application model identifier with the highest priority is determined in the target model identifier set, and at least one cell supporting the first application model identifier is determined as a candidate cell among the cells searched by the terminal device, within the range of candidate cells , the terminal device determines the target cell according to the S criterion.

In a possible implementation manner, the first application model identifier with the highest priority in the target model identifier set is selected, and when it is determined that all the searched cells do not support the first application model identifier, the terminal device uses the S criterion in the Determine the target cell among the searched cells.

Exemplarily, if all candidate cells within the range of candidate cells do not satisfy the S criterion, cell selection is performed among the cells searched by the terminal device, and within the range of cells searched by the terminal device, the terminal device determines the target cell according to the S criterion, And select this cell to reside in.

For example, as shown in Figure 4, the terminal device determines the set of target model identifiers, where the model identifier corresponding to AI model identifier 1 has a priority of 1, the model identifier corresponding to AI model identifier 2 has a priority of 2, and the model corresponding to AI model identifier 3 The identification priority is 3, and the model identification priority corresponding to AI model identification 4 is 4. The highest priority in the target model ID set is AI model ID 1. The terminal device searches for cell A and cell B. Among the cells searched by the terminal device, only cell A supports the AI model ID 1 with the highest priority. Therefore, cell A As a candidate cell, judge whether cell A can be used as a target cell to camp on according to the S criterion; if neither cell A nor cell B found by the terminal device supports the AI model identification with the highest priority, the terminal device will not consider the model identification priority Level, judge the searched cell A and cell B directly according to the S criterion.

Mode 4: Select the second application model identification with the i-th highest priority in the target model identification set, determine at least one cell that supports the second application model identification as a candidate cell, and determine the target cell among the candidate cells according to the S criterion; otherwise, in When it is determined that all the searched cells do not support the second application model identifier, select the third application model identifier with the i+1th highest priority in the target model identifier set, and determine at least one cell that supports the third application model identifier as the Candidate cells, determine the target cell among the candidate cells according to the S criterion; otherwise, perform the previous step again until a target cell is determined, where the initial value of i is 1.

In a possible implementation manner, the terminal device selects the second application model identifier with the i-th highest priority in the target model identifier set, and the terminal device determines at least one cell that supports the second application model identifier as a candidate cell. Determine the target cell among the candidate cells; otherwise, when it is determined that all the cells acquired by the search do not support the second application model identifier, select the third application model identifier with the highest priority i+1 in the target model identifier set, and determine the support At least one cell identified by the third application model is used as a candidate cell, and a target cell is determined among the candidate cells according to the S criterion. If none of the cells obtained by the terminal device through searching supports the second application model identifier and the third application model identifier, the terminal device determines the target cell from all the cells obtained through the search according to the S criterion.

In a possible implementation manner, the terminal device selects the second application model identifier with the i-th highest priority in the target model identifier set, and the terminal device determines at least one cell that supports the second application model identifier as a candidate cell. Determine the target cell among the candidate cells; otherwise, when it is determined that all the cells acquired by the search do not support the second application model identifier, select the third application model identifier with the highest priority i+1 in the target model identifier set, and determine the support At least one sub-district identified by the third application model is used as a candidate sub-district, and the target sub-district is determined in the candidate sub-districts according to the S criterion; otherwise, when it is determined that all the sub-districts acquired by the search do not support the third application model identification, select the target model identification set The fourth application model identification with the i+2 highest priority among them, and so on, are selected in sequence through the priority ordering of the application model identifications in the target model identification set, until a target cell is determined, and it is used as a candidate cell. Within the range of candidate cells, the terminal device determines the target cell according to the S criterion.

In a possible implementation manner, if all the cells obtained by the terminal device through search do not support any application model identification contained in the target model identification set, the terminal device determines the target cell from all the cells obtained through the search according to the S criterion .

For example, as shown in FIG. 4 , the terminal device determines a target model ID set, wherein the model ID corresponding to AI model ID 1 has a priority of 1, and the model ID corresponding to AI model ID 1 has the highest priority. When the cell A searched by the terminal device does not meet the S criterion, select the AI model ID 2 with the second highest priority. According to the judgment, cell B supports the AI model ID 2 with the second highest priority, so cell B is taken as the candidate cell. And according to the S criterion, it is judged whether the cell B can be used as the target cell for camping;

If the cell searched by the terminal device does not support the AI model ID 1 with the highest priority nor the AI model ID 2 with the second highest priority, perform the previous step again and select the AI model ID 3 with the third highest priority for judgment ; If all the cells searched by the terminal device do not support any model identification in the target model identification set, the terminal device does not consider the priority of the model identification, and directly judges the searched cells according to the S criterion.

To sum up, in the technical solution provided by the embodiment of the present application, the terminal device determines the candidate cell according to the relationship between the identification information of the application model supported by the searched cell and the target model identification set, and according to the determined candidate cell, in the candidate cell Within the range, the terminal device determines the target cell according to the S criterion. The technical solutions provided by the embodiments of the present application can enable a terminal device to select a cell that supports an application model required by the terminal device, thereby obtaining a more accurate cell selection result and improving user service experience.

Fig. 5 shows a flowchart of a cell reselection method provided by an exemplary embodiment of the present application. In this embodiment, this method is applied to terminal equipment. The method includes:

Step 501: The terminal device determines a target model identification set.

Optionally, the target model identification set determined by the terminal device may be obtained through the NAS of the terminal device, or the AS of the terminal device, or through a network device configuration process, which is not limited in this application.

Step 502: The terminal device performs cell reselection according to the model identification information of the application models supported by the cell and the target model identification set.

The identification information of the application model refers to information for uniquely identifying the application model.

The terminal device performs cell reselection according to the identification information of the application model supported by the serving cell and/or at least one neighboring cell and the target model identification set.

The method for the terminal device to perform cell reselection according to the model identification information of the application model supported by the cell and the target model identification set includes at least one of the following four methods:

Method 1: Determine at least one neighboring cell that has the largest number of elements intersecting with the target model logo set in the model identification set supported by the neighboring cell as a candidate neighboring cell, and determine the target reselection among the candidate neighboring cells according to the absolute frequency point priority cell reselection method. Choose a neighborhood.

Exemplarily, the target cell for reselection refers to a cell in a neighboring cell where the terminal device can perform reselection and camp on, and which is different from the current serving cell.

The terminal device determines the set of target model identifiers and the set of application model identifiers supported by the adjacent cell measured by the terminal device, and through comparison and judgment, at least one neighbor with the largest number of elements intersecting with the target model identifier set in the model identifier set supported by the adjacent cell The cell serves as a candidate neighboring cell, and within the scope of the candidate neighboring cell, the terminal device determines the target cell for reselection according to the absolute frequency point priority cell reselection method.

Within the range of candidate neighboring cells, the terminal device performs cell reselection according to the absolute frequency point priority cell reselection method. If the neighboring cell meets the requirements, the neighboring cell is considered to be a suitable neighboring cell, and the neighboring cell is used as the target reselected cell , and select the neighboring cell to reside in; if the neighboring cell does not meet the requirements, continue to judge the next candidate neighboring cell until a candidate neighboring cell meets the requirements.

If all candidate neighboring cells within the range of candidate neighboring cells do not meet the requirements, then cell reselection will be performed among all neighboring cells measured by the terminal device, and among all the neighboring cells measured by the terminal device, the terminal device will prioritize according to the absolute frequency point The super-level cell reselection method determines the target cell for reselection, and selects the neighboring cell for camping.

Exemplarily, the absolute frequency point priority cell reselection method includes reselection criteria for same-frequency adjacent cells and inter-frequency adjacent cell reselection criteria. The same-frequency adjacent cell refers to an adjacent cell with the same frequency point as the serving cell; the inter-frequency adjacent cell refers to an adjacent cell with a different frequency point from the serving cell.

The same-frequency adjacent cell reselection criterion, also known as the R criterion, is as follows:

Rs=Qmeas,s+Qhyst-Qoffset _temp

Rn=Qmeas, n-Qoffset-Qoffset _temp

In the formula, Rs is the R value of the serving cell, Rn is the R value of the neighboring cell, Qhyst is the hysteresis value of the sorting standard, Qmeas is the RSRP value of the reselected cell when the cell is reselected, and Qoffset is used to indicate that there is a suitable cell in the neighboring cell Qmeas,n of the cell at that time, when there is no suitable cell in the neighboring cell, Qmeas,n is 0, and Qoffset _temp is a temporary offset.

When the terminal device determines the target cell for reselection according to the absolute frequency point priority cell reselection method, if the adjacent cells of the terminal device include adjacent cells of the same frequency, the terminal device selects the adjacent cell with the highest R value among the adjacent cells of the same frequency as the The target reselects a cell for camping.

Inter-frequency adjacent cell reselection means that when performing cell reselection among multiple inter-frequency adjacent cells, if there is a high-priority inter-frequency adjacent cell that satisfies the high-priority cell reselection criteria, the terminal device will be reselected to the high-priority cell. Inter-frequency adjacent cells; when there is no suitable high-priority inter-frequency adjacent cell, the terminal device reselects to the same-frequency adjacent cell or the same priority different-frequency adjacent cell according to the same-frequency adjacent cell reselection criteria; When different-frequency adjacent cells of the same level, same-frequency adjacent cells, and different-frequency adjacent cells of the same priority are used, the terminal device reselects to a low-priority inter-frequency adjacent cell according to the low-priority cell reselection decision criteria.

For example, as shown in Figure 4, the terminal device determines the target model identification set, and the terminal device measures and obtains neighboring cell C and neighboring cell D. The model identification set supported by neighboring cell C includes AI model identification 3, and the adjacent cell D of the terminal device supports The set of model IDs includes AI model ID 1 and AI model ID 4. Through comparison and judgment, the number of intersection elements between the adjacent cell D and the target model ID set is the largest, so the adjacent cell D is used as a candidate adjacent cell, and according to the absolute frequency point priority The cell reselection method judges whether the neighboring cell D can be used as the target reselection cell for camping.

Method 2: Determine at least one neighboring cell whose number of intersection elements in the model identification set supported by the neighboring cell meets the second threshold with the target model identification set as a candidate neighboring cell, and select the candidate neighboring cell according to the absolute frequency point priority cell reselection method Determine the target reselection cell.

Exemplarily, the second threshold is a default value or configured through a network device.

The terminal device determines the model identification set supported by the adjacent cell, and compares it with the target model identification set of the terminal device. When the number of intersection elements in the model identification set supported by the adjacent cell and the target model identification set meets the second threshold, The neighboring cell is determined as a candidate neighboring cell, and within the range of the candidate neighboring cells, the terminal device determines the target cell for reselection according to the absolute frequency point priority cell reselection method.

If all candidate neighboring cells within the range of candidate neighboring cells do not meet the requirements, cell reselection will be performed among all neighboring cells measured by the terminal device. In all neighboring cells of the terminal device, the terminal device will prioritize the cells according to the absolute frequency point The reselection method determines the target reselected cell, and selects the neighboring cell for camping.

For example, as shown in Figure 4, the terminal device determines the target model identification set, and the terminal device measures and obtains neighboring cell C and neighboring cell D. The model identification set supported by neighboring cell C includes AI model identification 3, and the adjacent cell D of the terminal device supports The set of model identifications includes AI model identification 1 and AI model identification 4. Through comparison and judgment, the number of elements in the intersection of the adjacent cell D and the target model identification set meets the preset second threshold 2, so the adjacent cell D is selected as a candidate adjacent cell , and according to the absolute frequency point priority cell reselection method, it is judged whether the neighboring cell D can be used as the target reselected cell to camp on.

Method 3: Select the first application model identifier with the highest priority in the target model identifier set, determine at least one neighboring cell that supports the first application model identifier as a candidate neighbor cell, and select the candidate neighbor cell according to the absolute frequency point priority cell reselection method Determine the target reselection cell.

Exemplarily, the first application model identification with the highest priority is determined in the target model identification set, at least one adjacent cell that supports the first application model identification is determined as a candidate adjacent cell among the adjacent cells of the terminal device, and within the range of candidate adjacent cells Inside, the terminal device determines the target cell for reselection according to the absolute frequency point priority cell reselection method.

If all candidate neighboring cells within the range of candidate neighboring cells do not meet the requirements, cell reselection will be performed among all neighboring cells of the terminal device, and within the range of all neighboring cells of the terminal device, the terminal device will reselect cells according to the absolute frequency point priority The method determines the target cell for reselection, and selects the adjacent cell for camping.

For example, as shown in FIG. 4 , the terminal device determines a target model identifier set, and the model identifier corresponding to the AI model identifier has a priority of 1, and its model identifier has the highest priority. The highest priority in the target model identification set is the AI model identification 1. The terminal device measures and obtains neighboring cells C and neighboring cells D. Among the neighboring cells obtained by the terminal device measurement, the neighboring cell D supports the AI model identification 1 with the highest priority. Therefore Take the neighboring cell D as a candidate neighboring cell, and judge whether the neighboring cell D can be used as the target reselected cell to camp on according to the absolute frequency point priority cell reselection method; if the neighboring cell C and the neighboring cell D do not support the highest priority If the AI model ID is 1, the terminal device does not consider the priority of the model ID, and directly judges the neighbor cells obtained by measurement according to the absolute frequency point priority cell reselection method.

Method 4: Select the second application model ID with the i-th highest priority in the target model ID set, determine at least one neighboring cell that supports the second application model ID as a candidate neighboring cell, and reselect the candidate cell according to the absolute frequency point priority cell reselection method. Determine the target reselected cell in the neighboring cell; otherwise, if it is determined that all the neighboring cells obtained by measurement do not support the second application model identification, select the third application model identification with the i+1th highest priority in the target model identification set , determine at least one neighboring cell that supports the third application model identification as a candidate neighboring cell, and determine the target cell for reselection among the candidate neighboring cells according to the absolute frequency point priority cell reselection method; otherwise, perform the previous step again until one is determined The target cell for reselection, where the initial value of i is 1.

In a possible implementation manner, the terminal device selects the second application model identifier with the i-th highest priority in the target model identifier set, and determines at least one neighboring cell that supports the second application model identifier as a candidate neighboring cell. The priority cell reselection method determines the target reselected cell among the candidate neighbor cells; otherwise, if it is determined that all the neighbor cells acquired through measurement do not support the second application model identifier, select the priority i+th cell in the target model identifier set. 1 high third application model identification, determine at least one adjacent cell that supports the third application model identification as a candidate adjacent cell, and determine the target reselection cell in the candidate adjacent cells according to the absolute frequency point priority cell reselection method, starting from i The initial value is 1. If none of the adjacent cells of the terminal device support the second application model identifier and the third application model identifier, the terminal device determines the target cell for reselection from all the adjacent cells acquired through measurement according to the absolute frequency point priority cell reselection method.

In a possible implementation manner, the terminal device selects the second application model identifier with the i-th highest priority in the target model identifier set, and determines at least one neighboring cell that supports the second application model identifier as a candidate neighboring cell. The priority cell reselection method determines the target reselected cell among the candidate neighbor cells; otherwise, if it is determined that all the neighbor cells acquired through measurement do not support the second application model identifier, select the priority i+th cell in the target model identifier set. 1 high third application model identification, determine at least one neighboring cell that supports the third application model identification as a candidate neighboring cell, determine the target reselection cell among the candidate neighboring cells according to the absolute frequency point priority cell reselection method, and determine all In the case that none of the adjacent cells support the third application model identification, select the fourth application model identification with the i+2 highest priority in the target model identification set, and so on, through the priority of the application model identification in the target model identification set The sorting is performed sequentially until a target cell for reselection is determined.

Within the range of candidate neighboring cells, if the cell satisfies the absolute frequency point priority cell reselection method, the neighboring cell is considered to be a suitable neighboring cell, and the neighboring cell is used as the target reselecting cell, and the neighboring cell is selected for camping; If the neighbor cell does not meet the absolute frequency point priority cell reselection method, continue to judge the next candidate neighbor cell until a candidate neighbor cell meets the absolute frequency point priority cell reselection method.

For example, as shown in FIG. 4 , the terminal device determines a target model identifier set, and the model identifier corresponding to AI model identifier 1 has a priority of 1. If the neighbor cell D obtained by terminal measurement does not satisfy the absolute frequency point priority cell reselection method, select the AI model ID 2 with the second highest priority. According to the judgment, the neighbor cell D does not support the second highest priority cell reselection method. AI model ID 2, continue to perform the above steps, select the AI model ID 3 with the third highest priority, and the neighboring cell C supports the AI model ID 3 with the third highest priority, so the neighboring cell C is selected as the candidate neighboring cell, and according to The absolute frequency point priority cell reselection method judges whether the neighboring cell C can be used as the target reselected cell to reside;

If the adjacent cell of the terminal device does not support the AI model ID 1 with the highest priority nor the AI model ID 2 with the second highest priority, perform the previous step again, and select the AI model ID 3 with the third highest priority for judgment; If all the neighboring cells of the terminal device do not support any model identifier in the target model identifier set, the terminal device does not consider the priority of the model identifier, and directly performs the neighbor cell reselection method based on the absolute frequency point priority cell reselection method. judge.

Within the range of candidate neighboring cells, the terminal device determines the target reselection method according to the absolute frequency point priority cell reselection method. Choose a district.

Within the range of candidate neighbor cells, if the neighbor cell satisfies the absolute frequency point priority cell reselection method, the neighbor cell is considered to be a suitable neighbor cell, and the neighbor cell is used as the target reselection cell, and the neighbor cell is selected for camping ; If the neighbor cell does not meet the absolute frequency point priority cell reselection method, continue to judge the next candidate neighbor cell until a candidate neighbor cell meets the absolute frequency point priority cell reselection method.

If none of the adjacent cells measured and obtained by the terminal device support the second application model identifier and the third application model identifier, the terminal device determines the target cell for reselection from all the cells obtained by measurement according to the frequency point priority cell reselection method.

In a possible implementation manner, the terminal device selects the second application model identifier with the i-th highest priority in the target model identifier set, determines to support the second application model identifier, and the application model priority information corresponding to the second application model identifier At least one neighbor cell with the highest relative value is used as a candidate neighbor cell, and the target reselection cell is determined among the candidate neighbor cells according to the absolute frequency point priority cell reselection method; otherwise, all the neighbor cells acquired during the determination measurement do not support the second application model In the case of identification, select the third application model identification with the i+1th highest priority in the target model identification set, confirm that the third application model identification is supported, and the application model priority information corresponding to the third application model identification is relatively highest at least A neighbor cell is used as a candidate neighbor cell, and the target reselection cell is determined among the candidate neighbor cells according to the absolute frequency point priority cell reselection method; otherwise, when it is determined that all the neighbor cells acquired through measurement do not support the third application model identification , select the fourth application model ID with the i+2 highest priority in the target model ID set, and so on, perform reselection according to the priority order of the application model IDs in the target model ID set until a target reselection cell is determined .

In a possible implementation manner, if all the neighboring cells obtained by the terminal device measurement do not support any of the application model identifications contained in the target model identification set, the terminal device uses the absolute frequency points from all the neighboring cells obtained by the measurement The priority cell reselection method determines the target cell for reselection.
