Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Before describing the cell selection method provided in the embodiments of the present application in detail, a mobile communication system related to the embodiments of the present application is first described in brief.

Referring to fig. 1, a schematic diagram of a mobile communication system according to an embodiment of the present application is shown. The network architecture may include: terminal device 10, network device 20, and core network device 30.

The terminal device 10 may refer to a UE (User Equipment), an access terminal device, a subscriber unit, a subscriber station, a mobile station, a remote terminal device, a mobile device, a wireless communication device, a User agent, or a User Equipment. Alternatively, the terminal device 10 may also be a cellular phone, a cordless phone, a SIP (Session Initiation Protocol ) phone, a WLL (Wireless Local Loop, wireless local loop) station, a PDA (Personal digital Assistant), a handheld device with a wireless communication function, a computing device, or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in 5GS (5 th Generation System, fifth generation mobile communication system), or a terminal device in a future evolved PLMN (public Land mobile communication Network), or the like, to which the embodiment of the present application is not limited. For convenience of description, the above-mentioned devices are collectively referred to as terminal device devices. The number of terminal devices 10 is typically plural, and one or more terminal devices 10 may be distributed within a cell managed by each network device 20.

The network device 20 is a device deployed in an access network to provide wireless communication functionality for the terminal device 10. The network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. The names of network device-capable devices may vary in systems employing different radio access technologies, for example in 5G NR systems, called gndeb or gNB. As communication technology evolves, the name "network device" may change. For convenience of description, in the embodiment of the present application, the above-mentioned apparatus for providing the terminal device 10 with the wireless communication function is collectively referred to as a network device. Alternatively, a communication relationship may be established between the terminal device 10 and the core network device 30 through the network device 20. Illustratively, in an LTE (Long Term Evolution ) system, the network device 20 may be EUTRAN (Evolved Universal Terrestrial Radio Access Network, evolved universal terrestrial radio network) or one or more enodebs in EUTRAN; in a 5G NR system, the network device 20 may be a RAN (Radio Access Network ) or one or more gnbs in the RAN. In the embodiments of the present application, the network device refers to the network device 20 unless specifically described.

The core network device 30 mainly functions to provide user connection, management of users, and bearer completion of services, and to provide an interface to an external network as a bearer network. For example, core network devices in the 5G NR system may include AMF (Access and Mobility Management Function ) entities, UPF (User Plane Function, user plane function) entities, SMF (Session Management Function ) entities, and the like.

In one example, the network device 20 and the core network device 30 communicate with each other via some air interface technology, such as an NG interface in a 5G NR system. The network device 20 and the terminal device 10 communicate with each other via some kind of air interface technology, e.g. Uu interface.

The "5G NR system" in the embodiments of the present application may also be referred to as a 5G system or an NR system, but a person skilled in the art may understand the meaning thereof. The technical scheme described in the embodiment of the application can be applied to a 5G NR system and also can be applied to a subsequent evolution system of the 5G NR system.

The communication system typically supports a cell selection procedure for the terminal device. When a user desiring to use a network service selects a cell, the system connects the user with the selected cell via a communication link, i.e., performs a cell selection procedure. Thus, the terminal device may switch from the idle state to the cell of the first network device.

The communication system typically supports a cell reselection procedure for the terminal device. When a user who needs to use network services moves from one cell to another cell, or due to adjustment of radio transmission traffic load, active operation maintenance, equipment failure, etc., in order to ensure continuity of communication and quality of service, the system needs to transfer the communication link between the user and the original cell to the new cell, i.e. execute a cell handover procedure. Thus, the terminal device may 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 according to an exemplary embodiment of the present application. The embodiment is applied to the terminal equipment by the method. The method comprises the following steps:

step 201: and the terminal equipment performs cell selection or cell reselection according to the model related information of the application model supported by at least one cell.

In one possible implementation, the application model refers to a model applied in a communication system, where the application model includes at least one of an artificial intelligence (Artificial Intelligence, AI) model, a machine learning model, an authentication model, an encryption model, and a decryption model, which is not limited in this application.

Alternatively, the AI model refers to a model that predicts certain information, data, or decisions in the course of mobile communications; the authentication model is a model for authenticating certain access information and input data in the mobile communication process; the encryption model refers to a model for encrypting certain signaling and/or data in the mobile communication process; the decryption model refers to a model that decrypts certain signaling and/or data during mobile communication.

In the cell selection process, the application model supported by the cell refers to an application model that can be supported by at least one cell in the n searched cells.

In the process of cell reselection, an application model supported by a cell refers to an application model that can be supported by a serving cell and/or at least one neighboring cell.

In one possible implementation manner, the model related information of the application model includes at least one of model identification information of the application model, priority information corresponding to the application model, and precision level information corresponding to the application model, which is not limited in this application. The model identification information of the application model refers to identification information for uniquely identifying the application model; priority information corresponding to the application model refers to priority information of the application model, and the priority information of the same application model in different terminal devices may be different; the precision grade information corresponding to the application model refers to operation precision information of different application models.

Illustratively, when the terminal device is powered on or enters a coverage area from a blind area, a suitable cell is selected among the at least one cell for camping by searching for a public land mobile network (Public Land Mobile Network, PLMN) allowed frequency point.

The cell reselection refers to that the terminal equipment selects a cell meeting the cell reselection rule to provide service by monitoring the signal intensity and quality of the neighbor cell and the service cell and the application model related information supported by the cell in an idle state or an inactive state. Through cell reselection, the terminal equipment in an idle state or an inactive state can be ensured to reside in a proper cell to the greatest extent. The serving cell refers to a cell in which the terminal device is currently located.

The neighbor cells are relative to the serving cells, that is, other cells around the serving cells are simply referred to, the terminal device determines one or more neighbor cells through a measurement process, and optionally, in order to assist the terminal device to quickly measure the neighbor cells, the serving cells inform the terminal device of information such as frequency point information, a synchronization signal window and the like of the neighbor cells through a system broadcast message, so as to assist the terminal device to measure the neighbor cells.

In one possible implementation, measurement assistance information of some cells or frequency points may be preconfigured in the terminal device, so as to assist the terminal device in making cell measurements.

In summary, according to the technical solution provided in the embodiments of the present application, the terminal device performs cell selection or cell reselection according to the model related information of the application model supported by at least one cell. The technical scheme provided by the embodiment of the application model selection method and the terminal equipment can enable the terminal equipment to select the cell supporting the application model required by the terminal equipment, so that more accurate cell selection or reselection results are obtained, and user service experience is improved.

Fig. 3 shows a flowchart of a cell selection method according to an exemplary embodiment of the present application. The embodiment is applied to the terminal equipment by the method. The method comprises the following steps:

step 301: the terminal device determines a set of object model identifications.

The target model identification set is an identification information set of an application model expected to be obtained by the terminal device, and the target model identification set contains identification information of at least one application model.

Alternatively, the set of target model identifiers determined by the terminal device may be obtained through a Non-Access Stratum (NAS) of the terminal device, or through an Access Stratum (AS) of the terminal device, or through a network device configuration procedure, which is not limited in this application.

Step 302: and the terminal equipment performs cell selection according to the model identification information of the application model 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.

The terminal device determines 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 the target cell, the terminal device selects the target cell to reside.

The mode of the terminal equipment for selecting the cell according to the model identification information of the application model supported by the cell and the target model identification set comprises at least one of the following four modes:

mode one: and determining at least one cell with the largest number of intersection elements with the target model identification set in the model identification set supported by the searched cell as a candidate cell, and determining the target cell in the candidate cell according to an S criterion.

The target cell is, for example, a cell in which the terminal device can camp among cells searched by the terminal device.

The terminal equipment determines a target model identification set and an application model identification set supported by a cell searched by the terminal equipment, and takes at least one cell with the largest intersection element number with the target model identification set in the model identification set supported by the searched cell as a candidate cell through comparison and judgment, and the terminal equipment determines the target cell according to an S criterion in the range of the candidate cell.

In the range of the candidate cell, if the cell meets the S criterion, the cell is considered to be a proper cell, the cell is taken as a target cell, and the cell is selected to reside; if the cell does not meet the S criterion, the next candidate cell is continuously judged until a certain candidate cell meets the S criterion.

If all the candidate cells within the candidate cell range do not meet the S criterion, selecting the cell from the cells searched by the terminal equipment, determining a target cell by the terminal equipment according to the S criterion in the cell range searched by the terminal equipment, and selecting the cell for residence.

The technical scheme provided by the embodiment of the application can be applied to an NTN system and a cellular network system.

The S criterion refers to a basic condition that the terminal device can be camping on a cell, and means that the cell can provide a service level that meets the S criterion, that is, it is possible to become a target cell for cell selection only when the measurement evaluation result of a cell meets the S criterion.

The S criteria specify:

srxlev >0 and square >0

Wherein Srxlev is the received power in cell search; the square is the received signal quality in the cell search; the expressions of Srxlev and square are shown below, respectively:

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 received power (Reference Signal Receiving Power, RSRP) actually measured and calculated by the terminal device.

Qqualmeas is the reference signal received quality (Reference Signal Receiving Quality, RSRQ) calculated for the actual measurement by the terminal device.

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

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

Qrxlevminoffset and Qqualminoffset are offsets that prevent ping-pong effects between two public land mobile networks (Public Land Mobile Network, PLMNs) due to radio environment fluctuations, that is, qrxlevminoffset and Qqualminoffset are offsets for Qrxlevmin and Qqualmin, respectively, that are considered when the terminal device resides on a visiting public land mobile network (Visited Public Land Mobile Network, VPLMN) periodically searching for higher priority PLMNs.

Pcompensation is power compensation, for example, when the maximum allowed transmit power of the network device is greater than the maximum uplink transmit power determined by the capability of the terminal device itself, due to low power of the terminal device.

Qoffsetemp is only used for special scenes, and is not applicable to normal situations, such as a "kiloleaf problem" scene.

Since RSRP represents reference signal received power, qrxlevmeas- (qrxlevmin+qrxlevminoffset) indicates downlink received signal quality, pcompensation indicates uplink transmitted signal quality, and Srxlev is an evaluation value that is evaluated by comprehensively considering uplink and downlink signal power strength, and that can represent quality of service that can be provided by a cell, with respect to RSRP. RSRQ, as a signal quality metric value that comprehensively considers RSRP and total received power (including interference and noise effects), can provide a more reliable basis for evaluation than RSRP, so square also represents the cell service level. The quality of service available to the cell can be more fully evaluated by Srxlev and square. The S criterion is therefore the basic evaluation condition as to whether a cell can camp on.

In one possible implementation manner, when the terminal device performs cell selection, by measuring the Qrxlevmeas value and Qqualmeas of the searched cell, acquiring other parameters in the S criterion formula through the system information and the self capability level of the cell, calculating to obtain Srxlev and square, and then comparing with 0, if Srxlev >0 and square >0, that is, the cell meets the S criterion, the terminal device considers that the cell meets the signal quality requirement of cell selection, and can select the cell as the resident cell. If the system information of the cell is broadcast that it is allowed to camp on, the terminal will choose to camp on this cell.

For example, as shown in fig. 4, the terminal device determines a target model identifier set, the terminal device searches for a cell a and a cell B, the model identifier set supported by the cell a searched by the terminal device includes an AI model identifier 1, the model identifier set supported by the cell B searched by the terminal device includes an AI model identifier 2, an AI model identifier 3 and an AI model identifier 4, and by comparing and judging, the intersection element number of the cell B and the target model identifier set is the largest, so the cell B is used as a candidate cell, and whether the cell B can reside as a target cell is judged according to an S criterion.

Mode two: and determining at least one cell which meets a first threshold value in the number of intersection elements of the model identification set supported by the searched cell and the target model identification set as a candidate cell, and determining the target cell in the candidate cells according to an S criterion.

The first threshold is illustratively a default value or configured by the network device.

The terminal equipment determines a model identification set supported by a cell in the searched cell, compares the model identification set supported by the cell with a target model identification set determined by the terminal equipment, determines the cell as a candidate cell under the condition that the number of intersection elements in the model identification set supported by the cell and the target model identification set meets a first threshold value, and determines the target cell according to an S criterion in the range of the candidate cell.

For example, as shown in fig. 4, the terminal device determines a target model identifier set, the terminal device searches for a cell a and a cell B, the model identifier set supported by the cell a searched by the terminal device includes an AI model identifier 1, the model identifier set supported by the cell B searched by the terminal device includes an AI model identifier 2, an AI model identifier 3 and an AI model identifier 4, and by comparing and judging, the number of intersection elements of the cell B and the target model identifier set meets a preset first threshold 2, so that the cell B is used as a candidate cell, and whether the cell B can reside as a target cell is judged according to an S criterion.

Mode three: and selecting a first application model identifier with the highest priority in the target model identifier set, determining at least one cell supporting the first application model identifier as a candidate cell, and determining a target cell in the candidate cells according to an S criterion.

Alternatively, the priority of the application model identifier in the target model identifier set determined by the terminal device may be provided by NAS of the terminal device, or determined based on AS implementation of the terminal device, or obtained from a network device configuration procedure by the terminal device, which is not limited in this application.

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

In one possible implementation manner, a first application model identifier with the highest priority in the target model identifier set is selected, and the terminal device determines a target cell in the searched cells according to the S criterion under the condition that all the searched cells are determined not to support the first application model identifier.

If all candidate cells within the candidate cell range do not meet the S criterion, cell selection is performed in the cells searched by the terminal device, and in the cell range searched by the terminal device, the terminal device determines a target cell according to the S criterion and selects the cell for residence.

For example, as shown in fig. 4, the terminal device determines the target model identifier set, where the model identifier priority corresponding to the AI model identifier 1 is 1, the model identifier priority corresponding to the AI model identifier 2 is 2, the model identifier priority corresponding to the AI model identifier 3 is 3, and the model identifier priority corresponding to the AI model identifier 4 is 4. The highest priority in the target model identification set is AI model identification 1, the terminal equipment searches cell A and cell B, and only cell A supports AI model identification 1 with the highest priority in the cells searched by the terminal equipment, so that the cell A is used as a candidate cell, and whether the cell A can be used as a target cell for residence is judged according to an S criterion; if the cell A and the cell B searched by the terminal equipment do not support the AI model identification with the highest priority, the terminal equipment directly judges the searched cell A and cell B according to the S criterion without considering the priority of the model identification.

Mode four: selecting a second application model identifier with the i-th highest priority in the target model identifier set, determining at least one cell supporting the second application model identifier as a candidate cell, and determining a target cell in the candidate cells according to an S criterion; otherwise, under the condition that all the searched cells do not support the second application model identification, selecting a third application model identification with the (i+1) th high priority in the target model identification set, determining at least one cell supporting the third application model identification as a candidate cell, and determining a target cell in the candidate cell according to an S criterion; otherwise, the previous step is performed again until a target cell is determined, wherein the starting value of i is 1.

In one possible implementation manner, the terminal device selects a second application model identifier with the i-th highest priority in the target model identifier set, determines at least one cell supporting the second application model identifier as a candidate cell, and determines a target cell in the candidate cells according to an S criterion; otherwise, under the condition that all cells obtained through searching are not supported by the second application model identification, selecting a third application model identification with the (i+1) th high priority in the target model identification set, determining at least one cell supporting the third application model identification as a candidate cell, and determining the target cell in the candidate cell according to an S criterion. And if all the cells obtained by searching by the terminal equipment do not support the second application model identifier and the third application model identifier, the terminal equipment determines a target cell according to the S criterion from all the cells obtained by searching.

In one possible implementation manner, the terminal device selects a second application model identifier with the i-th highest priority in the target model identifier set, determines at least one cell supporting the second application model identifier as a candidate cell, and determines a target cell in the candidate cells according to an S criterion; otherwise, under the condition that all cells obtained by searching are not supported by the second application model identifier, selecting a third application model identifier with the (i+1) th high priority in the target model identifier set, determining at least one cell supporting the third application model identifier as a candidate cell, and determining a target cell in the candidate cell according to an S criterion; otherwise, under the condition that all cells obtained by searching do not support the third application model identification, selecting a fourth application model identification with the i+2-th high priority in the target model identification set, and so on, sequentially selecting through the priority ordering of the application model identifications in the target model identification set until a target cell is determined, taking the target cell as a candidate cell, and determining the target cell by the terminal equipment according to the S criterion in the range of the candidate cell.

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

For example, as shown in fig. 4, the terminal device determines the target model identifier set, where the model identifier priority corresponding to the AI model identifier 1 is 1, and the model priority corresponding to the AI model identifier 1 is the highest. Selecting an AI model identifier 2 with a higher priority under the condition that the cell A searched by the terminal equipment does not meet the S criterion, and judging whether the cell B can be used as a target cell for residence according to the judgment that the cell B supports the AI model identifier 2 with the higher priority, so the cell B is used as a candidate cell;

if the cell searched by the terminal equipment does not support the AI model identification 1 with the highest priority and the AI model identification 2 with the next highest priority, the previous step is executed again, and the AI model identification 3 with the third highest priority is selected for judgment; if all the cells searched by the terminal equipment do not support any model identifier in the target model identifier set, the terminal equipment directly judges the searched cells according to the S criterion without considering the priority of the model identifier.

In summary, according to the technical solution provided in the embodiments of the present application, the terminal device determines the candidate cell according to the relationship between the identifier information of the application model supported by the searched cell and the identifier set of the target model, and determines the target cell according to the S criterion within the range of the candidate cell according to the determined candidate cell. The technical scheme provided by the embodiment of the application model selection method and the terminal equipment can enable the terminal equipment to select the cell supporting the application model required by the terminal equipment, so that a more accurate cell selection result is obtained, and user service experience is improved.

Fig. 5 shows a flowchart of a cell reselection method provided in an exemplary embodiment of the present application. The embodiment is applied to the terminal equipment by the method. The method comprises the following steps:

step 501: the terminal device determines a set of object model identifications.

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

Step 502: and the terminal equipment reselects the cell according to the model identification information of the application model 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.

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

The mode of the terminal equipment for cell reselection according to the model identification information of the application model supported by the cell and the target model identification set comprises at least one of the following four modes:

mode one: and determining at least one neighbor cell with the largest number of intersection elements with the target model identification set in the model identification set supported by the neighbor cell as a candidate neighbor cell, and determining a target reselection cell in the candidate neighbor cell according to an absolute frequency point priority cell reselection method.

The target reselection cell is illustratively a cell in which the terminal device is capable of reselection, camping on, and is different from the current serving cell in the neighbor cell.

The terminal equipment determines a target model identification set and an application model identification set supported by the neighbor cells measured by the terminal equipment, and determines at least one neighbor cell with the largest intersection element number with the target model identification set in the model identification set supported by the neighbor cells as a candidate neighbor cell through comparison and judgment, wherein in the range of the candidate neighbor cell, the terminal equipment determines a target reselection cell according to an absolute frequency point priority cell reselection method.

In the range of candidate neighbor cells, the terminal equipment performs cell reselection according to an absolute frequency point priority cell reselection method, if the neighbor cells meet the requirements, the neighbor cells are considered to be suitable neighbor cells, the neighbor cells are taken as target reselection cells, and the neighbor cells are selected for residence; if the neighbor cells do not meet the requirements, continuing to judge the next candidate neighbor cell until a certain candidate neighbor cell meets the requirements.

If all the candidate neighbor cells in the range of the candidate neighbor cells do not meet the requirements, cell reselection is carried out in all the neighbor cells measured by the terminal equipment, and in all the neighbor cell ranges measured by the terminal equipment, the terminal equipment determines a target reselection cell according to an absolute frequency point priority cell reselection method and selects the neighbor cell for residence.

The absolute frequency point priority cell reselection method comprises the same-frequency neighbor cell reselection criterion and the different-frequency neighbor cell reselection criterion. The same-frequency neighbor cell refers to a neighbor cell with the same frequency point as the serving cell; the inter-frequency neighbor cell refers to a neighbor cell different from the serving cell in frequency point.

The co-frequency neighbor cell reselection criterion, also called R criterion, is as follows:

Rs＝Qmeas,s+Qhyst-Qoffset _temp

Rn＝Qmeas,n-Qoffset-Qoffset _temp

wherein Rs is the R value of a serving cell, rn is the R value of a neighbor cell, qhyst is the hysteresis value of a ranking criterion, qmeas is the RSRP value of a reselected cell during cell reselection, qoffset is used for representing Qmeas, n of a cell when a proper cell exists in the neighbor cell, and Qmeas, n is 0 when the proper cell does not exist in the neighbor cell _temp Is a temporary offset.

When the terminal equipment determines a target reselection cell according to the absolute frequency point priority cell reselection method, if the neighboring cells of the terminal equipment comprise the same-frequency neighboring cells, the terminal equipment selects the neighboring cell with the highest R value ranking in the same-frequency neighboring cells as the target reselection cell for residence.

The inter-frequency neighbor cell reselection refers to that when cell reselection is performed in a plurality of inter-frequency neighbor cells, if a high-priority inter-frequency neighbor cell meets a high-priority cell reselection decision criterion, the terminal equipment reselects to the high-priority inter-frequency neighbor cell; when the proper high-priority different-frequency neighbor cells do not exist, the terminal equipment reselects the same-frequency neighbor cells or the same-priority different-frequency neighbor cells according to the same-frequency neighbor cell reselection criterion; when there is no suitable high priority different frequency adjacent cell, same frequency adjacent cell and same priority different frequency adjacent cell, the terminal equipment reselects to the low priority different frequency adjacent cell according to the low priority cell reselection decision criterion.

For example, as shown in fig. 4, the terminal device determines a target model identifier set, the terminal device measures and obtains a neighboring cell C and a neighboring cell D, the model identifier set supported by the neighboring cell C includes an AI model identifier 3, the model identifier set supported by the neighboring cell D of the terminal device includes an AI model identifier 1 and an AI model identifier 4, and by comparing and judging, the number of intersection elements of the neighboring cell D and the target model identifier set is the largest, so that the neighboring cell D is used as a candidate neighboring cell, and whether the neighboring cell D can be used as a target reselection cell for residence is judged according to an absolute frequency point priority cell reselection method.

Mode two: and determining at least one neighbor cell, which is supported by the neighbor cells and has the number of intersection elements with the target model identification set, in the model identification set as a candidate neighbor cell, and determining the target reselection cell in the candidate neighbor cell according to an absolute frequency point priority cell reselection method.

The second threshold is illustratively a default value or configured by the network device.

The terminal equipment determines a model identification set supported by the neighbor cell, compares the model identification set supported by the neighbor cell with a target model identification set of the terminal equipment, determines the neighbor cell as a candidate neighbor cell under the condition that the number of intersection elements in the model identification set supported by the neighbor cell and the target model identification set meets a second threshold value, and determines a target reselection cell according to an absolute frequency point priority cell reselection method in the range of the candidate neighbor cell.

If all the candidate neighbor cells in the range of the candidate neighbor cells do not meet the requirements, cell reselection is carried out in all the neighbor cells obtained by measurement of the terminal equipment, in the range of all the neighbor cells of the terminal equipment, the terminal equipment determines a target reselection cell according to an absolute frequency point priority cell reselection method, and the neighbor cells are selected for residence.

For example, as shown in fig. 4, the terminal device determines a target model identifier set, the terminal device measures and obtains a neighboring cell C and a neighboring cell D, the model identifier set supported by the neighboring cell C includes an AI model identifier 3, the model identifier set supported by the neighboring cell D of the terminal device includes an AI model identifier 1 and an AI model identifier 4, and by comparing and judging, the number of intersection elements of the neighboring cell D and the target model identifier set meets a preset second threshold 2, so that the neighboring cell D is used as a candidate neighboring cell, and whether the neighboring cell D can be used as a target reselection cell for residence is judged according to an absolute frequency point priority cell reselection method.

Mode three: selecting a first application model identifier with highest priority in a target model identifier set, determining at least one neighbor cell supporting the first application model identifier as a candidate neighbor cell, and determining a target reselection cell in the candidate neighbor cells according to an absolute frequency point priority cell reselection method.

In an exemplary embodiment, a first application model identifier with the highest priority is determined in the target model identifier set, at least one neighboring cell supporting the first application model identifier is determined as a candidate neighboring cell in neighboring cells of the terminal device, and in the range of the candidate neighboring cell, the terminal device determines a target reselection cell according to an absolute frequency point priority cell reselection method.

If all the candidate neighbor cells in the range of the candidate neighbor cells do not meet the requirements, cell reselection is carried out in all the neighbor cells of the terminal equipment, and in the range of all the neighbor cells of the terminal equipment, the terminal equipment determines a target reselection cell according to an absolute frequency point priority cell reselection method and selects the neighbor cells for residence.

For example, as shown in fig. 4, the terminal device determines the target model identifier set, and the model identifier corresponding to the AI model identifier has a priority of 1, and the model identifier has the highest priority. The highest priority in the target model identification set is AI model identification 1, the terminal equipment measures and acquires neighbor cell C and neighbor cell D, and among the neighbor cells obtained by the terminal equipment, the neighbor cell D supports the AI model identification 1 with the highest priority, so that the neighbor cell D is used as a candidate neighbor cell, and whether the neighbor cell D can be used as a target reselection cell for residence is judged according to an absolute frequency point priority cell reselection method; if the adjacent cell C and the adjacent cell D do not support the AI model identification 1 with the highest priority, the terminal equipment does not consider the priority of the model identification, and directly judges the adjacent cell obtained by measurement according to an absolute frequency point priority cell reselection method.

Mode four: selecting a second application model identifier with the i-th highest priority in the target model identifier set, determining at least one neighbor cell supporting the second application model identifier as a candidate neighbor cell, and determining a target reselection cell in the candidate neighbor cells according to an absolute frequency point priority cell reselection method; otherwise, under the condition that all neighbor cells obtained through measurement are not supported by the second application model identifier, selecting a third application model identifier with the (i+1) th high priority in a target model identifier set, determining at least one neighbor cell supporting the third application model identifier as a candidate neighbor cell, and determining a target reselection cell in the candidate neighbor cells according to an absolute frequency point priority cell reselection method; otherwise, the previous step is performed again until a target reselection cell is determined, wherein the starting value of i is 1.

In a possible implementation manner, the terminal equipment selects a second application model identifier with the i-th highest priority in the target model identifier set, determines at least one neighbor cell supporting the second application model identifier as a candidate neighbor cell, and determines a target reselection cell in the candidate neighbor cells according to an absolute frequency point priority cell reselection method; otherwise, under the condition that all neighbor cells obtained through measurement do not support the second application model identification, selecting a third application model identification with the (i+1) th high priority in the target model identification set, determining at least one neighbor cell supporting the third application model identification as a candidate neighbor cell, and determining a target reselection cell in the candidate neighbor cells according to an absolute frequency point priority cell reselection method, wherein the initial value of i is 1. And if all the neighbor cells of the terminal equipment do not support the second application model identifier and the third application model identifier, the terminal equipment determines a target reselection cell from all the neighbor cells obtained by measurement according to an absolute frequency point priority cell reselection method.

In a possible implementation manner, the terminal equipment selects a second application model identifier with the i-th highest priority in the target model identifier set, determines at least one neighbor cell supporting the second application model identifier as a candidate neighbor cell, and determines a target reselection cell in the candidate neighbor cells according to an absolute frequency point priority cell reselection method; otherwise, under the condition that all neighbor cells obtained through measurement do not support the second application model identification, selecting a third application model identification with the i+1-th high priority in the target model identification set, determining at least one neighbor cell supporting the third application model identification as a candidate neighbor cell, determining a target reselection cell in the candidate neighbor cells according to an absolute frequency point priority cell reselection method, under the condition that all neighbor cells are determined not to support the third application model identification, selecting a fourth application model identification with the i+2-th high priority in the target model identification set, and so on, sequentially selecting through the priority ordering of the application model identifications in the target model identification set until one target reselection cell is determined.

In the range of the candidate neighbor cell, if the cell meets the absolute frequency point priority cell reselection method, the neighbor cell is considered to be a proper neighbor cell, the neighbor cell is taken as a target reselection cell, and the neighbor cell is selected for residence; if the neighbor cells do not meet the absolute frequency point priority cell reselection method, continuing to judge the next candidate neighbor cell until a certain candidate neighbor cell meets the absolute frequency point priority cell reselection method.

For example, as shown in fig. 4, the terminal device determines the target model identifier set, and the model identifier priority corresponding to the AI model identifier 1 is 1. Under the condition that an absolute frequency point priority cell reselection method is not met in a neighbor cell D obtained by terminal measurement, selecting an AI model identifier 2 with a second highest priority, continuously executing the steps according to judgment that the neighbor cell D does not support the AI model identifier 2 with the second highest priority, selecting an AI model identifier 3 with a third highest priority, and supporting the AI model identifier 3 with the third highest priority by a neighbor cell C, so that the neighbor cell C is used as a candidate neighbor cell, and judging whether the neighbor cell C can be used as a target reselection cell for residence according to the absolute frequency point priority cell reselection method;

if the neighbor cell of the terminal equipment does not support the AI model identification 1 with the highest priority and the AI model identification 2 with the next highest priority, the previous step is executed again, and the AI model identification 3 with the third highest priority is selected for judgment; if all neighbor cells of the terminal equipment do not support any model identifier in the target model identifier set, the terminal equipment does not consider the priority of the model identifier, and directly judges the neighbor cells obtained by measurement according to an absolute frequency point priority cell reselection method.

In summary, according to the technical solution provided in the embodiments of the present application, the terminal device determines a candidate neighboring cell according to the relationship between the identification information of the application model supported by the neighboring cell and the target model identification set, and determines a target reselection cell according to the absolute frequency point priority cell reselection method within the range of the candidate neighboring cell according to the determined candidate neighboring cell. The technical scheme provided by the embodiment of the application model selection method and the terminal equipment can enable the terminal equipment to select the adjacent cell supporting the application model required by the terminal equipment, so that a more accurate cell reselection result is obtained, and user service experience is improved.

Fig. 6 shows a flowchart of a cell selection method according to an exemplary embodiment of the present application. The embodiment is applied to the terminal equipment by the method. The method comprises the following steps:

step 601: the terminal device determines a set of object model identifications.

Alternatively, the set of target model identifiers determined by the terminal device may be obtained through a Non-Access Stratum (NAS) of the terminal device, or an Access Stratum (AS) of the terminal device, or through a network device configuration procedure, which is not limited in this application.

Step 602: and the terminal equipment performs cell selection according to the model identification information of the application model supported by the cell, the priority information of the application model and the target model identification set.

mode one: and selecting a first application model identifier with the highest priority in the target model identifier set, determining to support the first application model identifier, and determining at least one cell with the application model priority information corresponding to the first application model identifier relatively highest as a candidate cell according to the S criteria, wherein the target cell is determined in the candidate cell.

In one possible implementation manner, the terminal device selects a first application model identifier with the highest priority in the target model identifier set, and determines a target cell in the searched cells according to the S criterion when it is determined that all the searched cells do not support the first application model identifier.

In one possible implementation manner, the terminal device selects a first application model identifier with the highest priority in the target model identifier set, determines at least one cell supporting the first application model identifier, takes at least one cell with the highest application model priority information corresponding to the first application model identifier in the at least one cell supporting the first application model identifier as a candidate cell, and determines the target cell according to the S criteria in the candidate cell range.

For example, as shown in fig. 7, the terminal device determines the target model identifier set, where the model identifier priority corresponding to the AI model identifier 1 is 1. Under the condition that the cells searched by the terminal equipment all support the AI model identification 1 with the highest priority, the priority information of the AI model corresponding to the AI model identification 1 in the cells supporting the AI model identification 1 with the highest priority is further judged, and according to comparison, the priority information of the AI model corresponding to the AI model identification 1 in the cell B is the highest, so the cell B is used as a candidate cell, and whether the cell B can be used as a target cell for residence is judged according to an S criterion.

Mode two: selecting a second application model identifier with the i-th highest priority in the target model identifier set, determining to support the second application model identifier, and determining at least one cell with the application model priority information corresponding to the second application model identifier relatively highest as a candidate cell according to the S criterion, wherein the target cell is determined in the candidate cell; otherwise, under the condition that all the searched cells do not support the second application model identification, selecting a third application model identification with the (i+1) th high priority in the target model identification set, determining at least one cell which supports the third application model identification and corresponds to the third application model identification and has the highest application model priority information as a candidate cell, and determining the target cell in the candidate cell according to the S criterion; otherwise, the previous step is performed again until a target cell is determined, wherein the starting value of i is 1.

In one possible implementation manner, the terminal device selects a 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 determines at least one cell with the application model priority information corresponding to the second application model identifier relatively highest as a candidate cell, and determines a target cell in the candidate cell according to an S criterion; otherwise, under the condition that all the searched cells do not support the second application model identification, selecting a third application model identification with the (i+1) th high priority in the target model identification set, determining to support the third application model identification, and determining at least one cell with the highest application model priority information corresponding to the third application model identification as a candidate cell according to the S criterion, wherein the candidate cell is determined to be the target cell. If all the cells obtained by searching by the terminal equipment do not support the second application model identification and the third application model identification, the terminal equipment determines a target cell according to the S criterion from all the cells obtained by searching.

In one possible implementation manner, the terminal device selects a 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 determines at least one cell with the application model priority information corresponding to the second application model identifier relatively highest as a candidate cell, and determines a target cell in the candidate cell according to an S criterion; otherwise, under the condition that all the searched cells do not support the second application model identification, selecting a third application model identification with the (i+1) th high priority in the target model identification set, determining at least one cell which supports the third application model identification and corresponds to the third application model identification and has the highest application model priority information as a candidate cell, and determining the target cell in the candidate cell according to the S criterion; otherwise, under the condition that all cells obtained by searching are not supported by the third application model identification, selecting a fourth application model identification with the i+2-th high priority in the target model identification set, and so on, sequentially selecting the fourth application model identification by the priority order of the application model identifications in the target model identification set until a target cell is determined.

For example, as shown in fig. 7, the terminal device determines the target model identifier set, and the model identifier priority corresponding to the AI model identifier 1 is 1. Under the condition that the cell A searched by the terminal equipment does not meet the S criterion, selecting an AI model identifier 2 with high priority, and according to judgment, both the cell A and the cell B support the AI model identifier 2 with high priority, but the priority information of an AI model corresponding to the AI model identifier 2 in the cell A is relatively highest, so the cell A is used as a candidate cell, and whether the cell A can be used as a target cell for residence is judged according to the S criterion;

if the cell searched by the terminal equipment does not support the AI model identification 1 with the highest priority and the AI model identification 2 with the next highest priority, the previous step is executed again, and the AI model identification 3 with the third highest priority is selected for further judgment; if all the cells searched by the terminal equipment do not support any model identifier in the target model identifier set, the terminal equipment does not consider the priority of the model identifier and the priority information of the application model, and the searched cells are directly judged according to the S criteria.

In summary, according to the technical solution provided in the embodiments of the present application, the terminal device determines the candidate cell according to the relation between the model identification information of the application model supported by the searched cell, the priority information of the application model and the target model identification set, and determines the target cell according to the S criterion within the range of the candidate cell according to the determined candidate cell. The technical scheme provided by the embodiment of the application model selection method and the terminal equipment can enable the terminal equipment to select the cell supporting the application model required by the terminal equipment, so that a more accurate cell selection result is obtained, and user service experience is improved.

Fig. 8 shows a flowchart of a cell selection method according to an exemplary embodiment of the present application. The embodiment is applied to the terminal equipment by the method. The method comprises the following steps:

Fig. 9 shows a flowchart of a cell selection method according to an exemplary embodiment of the present application. The embodiment is applied to the terminal equipment by the method. The method comprises the following steps:

Step 901: the terminal device determines a set of object model identifications.

Step 902: and the terminal equipment performs cell selection according to the model identification information of the application model supported by the cell, the priority information of the application model, the precision grade information of the application model and the target model identification set.

The terminal device determines according to the model identification information of the application model supported by the cell, the priority information of the application model, the precision level information of the application model and the target model identification set, and if the terminal device finds the target cell, the terminal device resides in the target cell.

The mode of the terminal equipment for selecting the cell according to the model identification information of the application model supported by the cell, the priority information of the application model, the precision grade information of the application model and the target model identification set comprises at least one of the following two modes:

Mode one: selecting a first application model identifier with highest priority in a target model identifier set, determining to support the first application model identifier, and determining at least one cell with the highest priority information and application model precision grade information of an application model corresponding to the first application model identifier as a candidate cell according to an S criterion, wherein the candidate cell is the target cell.

Alternatively, the selecting of at least one cell having the highest priority information and the highest accuracy class information of the application model corresponding to the application model identification as the candidate cell refers to selecting at least one cell having the highest priority information and the highest accuracy class information of the application model as the candidate cell, or selecting at least one cell having the highest sum of the priority information and the accuracy class information of the application model as the candidate cell.

For example, as shown in fig. 7, the terminal device determines the target model identifier set, and the model identifier priority corresponding to the AI model identifier 1 is 1. Under the condition that the cell A and the cell B which are searched by the terminal equipment support the AI model identification 1 with the highest priority, further judging the priority information and the precision grade information of the AI model corresponding to the AI model identification 1 in the cell supporting the AI model identification 1 with the highest priority, wherein the priority information of the AI model 1 in the cell A is 2 which is lower than the priority information of the AI model 1 in the cell B, and the precision grade information of the AI model 1 in the cell A is 1 which is higher than the precision grade information of the AI model in the cell B, so the cell A is used as a candidate cell, and judging whether the cell A can be used as a target cell for residence according to an S criterion.

Mode two: selecting a second application model identifier with the i-th highest priority in the target model identifier set, determining to support the second application model identifier, and determining at least one cell with the highest priority information of the application model corresponding to the second application model identifier and the highest application model precision grade information as a candidate cell according to an S criterion, wherein the target cell is determined in the candidate cell; otherwise, under the condition that all the searched cells do not support the second application model identification, selecting a third application model identification with the (i+1) th high priority in the target model identification set, determining to support the third application model identification, and determining at least one cell with the highest priority information of the application model corresponding to the third application model identification and the application model precision grade information as a candidate cell according to the S criterion, wherein the candidate cell is determined by the target cell; otherwise, the previous step is performed again until a target cell is determined, wherein the starting value of i is 1.

In one possible implementation manner, the terminal equipment selects a second application model identifier with the i-th highest priority in the target model identifier set, determines that the second application model identifier is supported, and at least one cell with the highest priority information and application model precision grade information of an application model corresponding to the second application model identifier is used as a candidate cell, and determines a target cell in the candidate cell according to an S criterion; otherwise, under the condition that all the searched cells do not support the second application model identification, selecting a third application model identification with the (i+1) th high priority in the target model identification set, determining to support the third application model identification, and determining at least one cell with the highest priority information and application model precision grade information of the application model corresponding to the third application model identification as a candidate cell according to the S criterion, wherein the candidate cell is determined by the target cell. If all the cells obtained by searching by the terminal equipment do not support the second application model identification and the third application model identification, the terminal equipment determines a target cell according to the S criterion from all the cells obtained by searching.

In one possible implementation manner, the terminal equipment selects a second application model identifier with the i-th highest priority in the target model identifier set, determines that the second application model identifier is supported, and at least one cell with the highest priority information and application model precision grade information of an application model corresponding to the second application model identifier is used as a candidate cell, and determines a target cell in the candidate cell according to an S criterion; otherwise, under the condition that all the searched cells do not support the second application model identification, selecting a third application model identification with the (i+1) th high priority in the target model identification set, determining to support the third application model identification, and determining at least one cell with the highest priority information of the application model corresponding to the third application model identification and the application model precision grade information as a candidate cell according to the S criterion, wherein the candidate cell is determined by the target cell; otherwise, under the condition that all cells obtained by searching are not supported by the third application model identification, selecting a fourth application model identification with the i+2-th high priority in the target model identification set, and so on, sequentially selecting the fourth application model identification by the priority order of the application model identifications in the target model identification set until a target cell is determined.

For example, as shown in fig. 7, the terminal device determines the target model identifier set, and the model identifier priority corresponding to the AI model identifier 1 is 1. Under the condition that the AI model identification 1 with the highest priority is not supported in the cell A and the cell B searched by the terminal equipment, the AI model identification 2 with the highest priority is selected, the cell A and the cell B support the AI model identification 2 with the highest priority, the priority information and the precision grade information of the AI model corresponding to the AI model identification 2 are further judged, the precision grade information of the AI model corresponding to the AI model identification 2 in the cell A is lower than the precision grade information of the AI model corresponding to the AI model identification 2 in the cell B by one level, and the priority information of the AI model corresponding to the AI model identification 2 in the cell A is higher than the priority information of the AI model in the cell B by one level, so the cell A and the cell B are used as candidate cells, and whether the cell A and the cell B can be used as target cells or not is judged according to the S criterion.

If the cell searched by the terminal equipment does not support the AI model identification 1 with the highest priority and the AI model identification 2 with the next highest priority, the previous step is executed again, and the AI model identification 3 with the third highest priority is selected for further judgment; if all the cells searched by the terminal equipment do not support any model identifier in the target model identifier set, the terminal equipment does not consider the priority of the model identifier, the priority information of the application model and the precision grade information of the application model, and the cells obtained by searching are directly judged according to the S criteria.

In summary, according to the technical solution provided in the embodiments of the present application, the terminal device determines the candidate cell according to the relation between the model identification information of the application model supported by the searched cell, the priority information of the application model, the precision level information of the application model and the target model identification set, and determines the target cell according to the S criterion within the range of the candidate cell according to the determined candidate cell. The technical scheme provided by the embodiment of the application model selection method and the terminal equipment can enable the terminal equipment to select the cell supporting the application model required by the terminal equipment, so that a more accurate cell selection result is obtained, and user service experience is improved.

In one possible implementation manner, the terminal device selects a first application model identifier with the highest priority in the target model identifier set, and determines a target reselection cell in the neighbor cells acquired by measurement according to an absolute frequency point priority cell reselection method under the condition that all neighbor cells acquired by measurement are determined not to support the first application model identifier.

In a possible implementation manner, the terminal device selects a first application model identifier with the highest priority in the target model identifier set, determines at least one neighboring cell supporting the first application model identifier, takes at least one neighboring cell with the highest application model priority information corresponding to the first application model identifier in the at least one neighboring cell supporting the first application model identifier as a candidate neighboring cell, and determines a target reselection cell according to an absolute frequency point priority cell reselection method in the range of the candidate neighboring cell.

In the range of the candidate neighbor cell, if the neighbor cell meets the absolute frequency point priority cell reselection method, the neighbor cell is considered to be a proper neighbor cell, the neighbor cell is taken as a target reselection cell, and the neighbor cell is selected for residence; if the neighbor cells do not meet the absolute frequency point priority cell reselection method, continuing to judge the next candidate neighbor cell until a certain candidate neighbor cell meets the absolute frequency point priority cell reselection method.

If all the candidate neighbor cells in the range of the candidate neighbor cells do not meet the absolute frequency point priority cell reselection method, cell reselection is carried out in the neighbor cells obtained by measurement of the terminal equipment, in the range of the neighbor cells obtained by measurement of the terminal equipment, the terminal equipment determines a target reselection cell according to the absolute frequency point priority cell reselection method, and selects the neighbor cells for residence.

For example, as shown in fig. 7, the terminal device determines the target model identifier set, and the model identifier priority corresponding to the AI model identifier 1 is 1. Under the condition that the terminal equipment measures and obtains the adjacent cell C and the adjacent cell D which both support the AI model identification with the highest priority, priority information of the AI model corresponding to the AI model identification 1 in the adjacent cell supporting the AI model identification 1 with the highest priority is further judged, and according to comparison, the priority information of the AI model corresponding to the AI model identification 1 in the adjacent cell C is relatively highest, so that the adjacent cell C is used as a candidate adjacent cell, and whether the adjacent cell C can be used as a target reselection cell for residence is judged according to an absolute frequency point priority cell reselection method.

Mode two: selecting a second application model identifier with the i-th highest priority in the target model identifier set, determining at least one neighbor cell which supports the second application model identifier and has the application model priority information corresponding to the second application model identifier and is relatively highest as a candidate neighbor cell, and determining a target reselection cell in the candidate neighbor cell according to an absolute frequency point priority cell reselection method; otherwise, under the condition that all neighbor cells obtained through measurement are not supported by the second application model identifier, selecting a third application model identifier with the (i+1) th high priority in the target model identifier set, determining at least one neighbor cell which supports the third application model identifier and has the highest application model priority information corresponding to the third application model identifier as a candidate neighbor cell, and determining a target reselection cell in the candidate neighbor cell according to an absolute frequency point priority cell reselection method; otherwise, the previous step is performed again until a target reselection cell is determined, wherein the starting value of i is 1.

In a possible implementation manner, the terminal equipment selects a 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 at least one neighbor cell with the application model priority information corresponding to the second application model identifier being relatively highest is used as a candidate neighbor cell, and determines a target reselection cell in the candidate neighbor cell according to an absolute frequency point priority cell reselection method; otherwise, under the condition that all neighbor cells obtained through measurement are not supported by the second application model identifier, selecting a third application model identifier with the (i+1) th high priority in the target model identifier set, determining at least one neighbor cell which supports the third application model identifier and has the highest application model priority information corresponding to the third application model identifier as a candidate neighbor cell, and determining a target reselection cell in the candidate neighbor cells according to an absolute frequency point priority cell reselection method. If all neighbor cells obtained by measurement of the terminal equipment do not support the second application model identifier and the third application model identifier, the terminal equipment determines a target reselection cell from all the cells obtained by measurement according to a cell reselection method with frequency point priority.

In a possible implementation manner, the terminal equipment selects a 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 at least one neighbor cell with the application model priority information corresponding to the second application model identifier being relatively highest is used as a candidate neighbor cell, and determines a target reselection cell in the candidate neighbor cell according to an absolute frequency point priority cell reselection method; otherwise, under the condition that all neighbor cells obtained through measurement are not supported by the second application model identifier, selecting a third application model identifier with the (i+1) th high priority in the target model identifier set, determining at least one neighbor cell which supports the third application model identifier and has the highest application model priority information corresponding to the third application model identifier as a candidate neighbor cell, and determining a target reselection cell in the candidate neighbor cell according to an absolute frequency point priority cell reselection method; otherwise, under the condition that all neighbor cells obtained through measurement are not supported by the third application model identification, selecting a fourth application model identification with the i+2-th high priority in the target model identification set, and so on, sequentially reselecting through the priority ordering of the application model identifications in the target model identification set until a target reselection cell is determined.

In one possible implementation manner, if all neighboring cells obtained by measurement of the terminal device do not support any application model identifier contained in the target model identifier set, the terminal device determines a target reselection cell according to an absolute frequency point priority cell reselection method from all neighboring cells obtained by measurement.

If all the candidate neighbor cells in the candidate neighbor cell range do not meet the absolute frequency point priority cell reselection method, cell reselection is performed in the neighbor cells obtained by measurement of the terminal equipment, and in the neighbor cell range obtained by measurement of the terminal equipment, the terminal equipment determines a target reselection cell according to the absolute frequency point priority cell reselection method and selects the neighbor cells for residence.

For example, as shown in fig. 7, the terminal device determines the target model identifier set, and the model identifier priority corresponding to the AI model identifier 1 is 1. Under the condition that the terminal equipment measures and obtains the AI model identification 1 with the highest priority not supported by the adjacent cell C and the adjacent cell D, selecting the AI model identification 2 with the highest priority, and judging whether the adjacent cell D can be used as a target reselection cell for residence according to the judgment that the adjacent cell D supports the AI model identification 2 with the highest priority and the AI model priority information corresponding to the AI model identification 2 is relatively highest, so that the adjacent cell D is used as a candidate adjacent cell and the absolute frequency point priority cell reselection method is adopted.

Mode three: selecting a first application model identifier with highest priority in a target model identifier set, determining at least one adjacent cell supporting an application model identifier, taking priority information of an application model corresponding to the first application model identifier as new frequency point priority of the corresponding adjacent cell in the at least one adjacent cell supporting the first application model identifier, determining the adjacent cell with the new frequency point priority as a candidate adjacent cell, and determining a target reselection cell in the candidate adjacent cell according to an absolute frequency point priority cell reselection method.

In an exemplary embodiment, a first application model identifier with a highest priority is determined in a target model identifier set determined by a terminal device, at least one neighboring cell supporting the first application model identifier is determined in neighboring cells measured and acquired by the terminal device, priority information of an application model corresponding to the first application model identifier is used as a new frequency point priority of the corresponding neighboring cell, the neighboring cell with the new frequency point priority is used as a candidate neighboring cell, and the terminal device determines a target reselection cell according to an absolute frequency point priority cell reselection method within the range of the candidate neighboring cell.

In one possible implementation manner, a first application model identifier with the highest priority in a target model identifier set is selected, and under the condition that all neighbor cells obtained by measurement are determined not to support the first application model identifier, the terminal equipment determines a target reselection cell in the neighbor cells obtained by measurement according to an absolute frequency point priority cell reselection method.

For example, as shown in fig. 11, the terminal device determines the target model identifier set, and the model identifier priority corresponding to the AI model identifier 1 is 1. The method comprises the steps that the highest priority in a target model identification set is AI model identification 1, a terminal device measures and acquires an adjacent cell C and an adjacent cell D, the adjacent cell D supports the AI model identification 1 with the highest priority, in the adjacent cell D supporting the AI model identification 1, model priority information of an AI model is used as new frequency point priority of the adjacent cell D, and the frequency point priority of the adjacent cell D is changed from 5 to 3, so that the adjacent cell D is used as a candidate adjacent cell, and whether the adjacent cell D can be used as a target reselection cell for residence is judged according to an absolute frequency point priority cell reselection method; if the terminal equipment measures that the acquired neighbor cell C and the neighbor cell D do not support the AI model identification 1 with the highest priority, the terminal equipment directly judges and reselects the neighbor cell obtained by measurement according to the absolute frequency point priority cell reselection method without considering the priority of the model identification.

Mode four: selecting a second application model identifier with a high priority level i in the target model identifier set, determining at least one neighbor cell supporting the second application model identifier, taking priority information of an application model corresponding to the second application model identifier as a new frequency point priority level of the corresponding neighbor cell in the at least one neighbor cell supporting the second application model identifier, determining the neighbor cell with the new frequency point priority level as a candidate neighbor cell, and determining a target reselection cell in the candidate neighbor cell according to an absolute frequency point priority cell reselection method; otherwise, under the condition that all neighbor cells obtained through measurement do not support the second application model identification, selecting a third application model identification with the (i+1) th high priority in a target model identification set, determining at least one neighbor cell supporting the third application model identification, taking priority information of an application model corresponding to the third application model identification as a new frequency point priority of a corresponding neighbor cell in the at least one neighbor cell supporting the third application model identification, determining the neighbor cell with the new frequency point priority as a candidate neighbor cell, and determining a target reselection cell in the candidate neighbor cell according to an absolute frequency point priority cell reselection method; otherwise, the previous step is performed again until a target reselection cell is determined, wherein the starting value of i is 1.

In a possible implementation manner, the terminal equipment selects a second application model identifier with a high priority in a target model identifier set, determines at least one neighbor cell supporting the second application model identifier, takes priority information of an application model corresponding to the second application model identifier as a new frequency point priority of a corresponding neighbor cell in the at least one neighbor cell supporting the second application model identifier, determines the neighbor cell with the new frequency point priority as a candidate neighbor cell, and determines a target reselection cell in the candidate neighbor cell according to an absolute frequency point priority cell reselection method; otherwise, under the condition that all neighbor cells obtained through measurement do not support the second application model identification, selecting a third application model identification with the (i+1) th high priority in the target model identification set, determining at least one neighbor cell supporting the third application model identification, taking priority information of an application model corresponding to the third application model identification as a new frequency point priority of a corresponding neighbor cell in the at least one neighbor cell supporting the third application model identification, determining the neighbor cell with the new frequency point priority as a candidate neighbor cell, and determining the target reselection cell in the candidate neighbor cell according to an absolute frequency point priority cell reselection method. If all neighbor cells obtained by measurement of the terminal equipment do not support the second application model identifier and the third application model identifier, the terminal equipment determines a target reselection cell from all the cells obtained by measurement according to a cell reselection method with frequency point priority.

In a possible implementation manner, the terminal equipment selects a second application model identifier with a high priority in a target model identifier set, determines at least one neighbor cell supporting the second application model identifier, takes priority information of an application model corresponding to the second application model identifier as a new frequency point priority of a corresponding neighbor cell in the at least one neighbor cell supporting the second application model identifier, determines the neighbor cell with the new frequency point priority as a candidate neighbor cell, and determines a target reselection cell in the candidate neighbor cell according to an absolute frequency point priority cell reselection method; otherwise, under the condition that all neighbor cells obtained through measurement do not support the second application model identification, selecting a third application model identification with the (i+1) th high priority in a target model identification set, determining at least one neighbor cell supporting the third application model identification, taking priority information of an application model corresponding to the third application model identification as a new frequency point priority of a corresponding neighbor cell in the at least one neighbor cell supporting the third application model identification, determining the neighbor cell with the new frequency point priority as a candidate neighbor cell, and determining a target reselection cell in the candidate neighbor cell according to an absolute frequency point priority cell reselection method; otherwise, under the condition that all neighbor cells obtained by measurement do not support the third application model identification, selecting a fourth application model identification with the i+2-th high priority in the target model identification set, and so on, sequentially selecting the application model identifications by the priority order of the application model identifications in the target model identification set until a target reselection cell is determined, wherein the initial value of i is 1.

For example, as shown in fig. 12, the terminal device determines that the target model identifier set includes an AI model identifier 1, an AI model identifier 2, an AI model identifier 3, and an AI model identifier 4, where the model identifier priority corresponding to the AI model identifier 1 is 1. Under the condition that the terminal equipment measures and acquires the AI model identification 1 with the highest priority in the adjacent cell C and the adjacent cell D, selecting the AI model identification 2 with the highest priority, according to judgment, the adjacent cell D supports the AI model identification 2 with the highest priority, in the adjacent cell D supporting the AI model identification 2, the model priority information of the AI model identification 2 is used as the new frequency point priority of the adjacent cell D, the frequency point priority of the adjacent cell D is changed from 5 to 1, so that the adjacent cell D is used as a candidate adjacent cell, and whether the adjacent cell D can be used as a target reselection cell for residence is judged according to an absolute frequency point priority cell reselection method.

If the terminal equipment measures that the acquired neighbor cell does not support the AI model identification 1 with the highest priority and the AI model identification 2 with the next highest priority, the last step is executed again, and the AI model identification 3 with the third highest priority is selected for judgment; if all neighbor cells obtained by measurement of the terminal equipment do not support any model identifier in the target model identifier set, the terminal equipment directly judges the neighbor cells obtained by measurement according to an absolute frequency point priority cell reselection method without considering the priority of the model identifier.
