It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0173] In order to enable those skilled in the art to better understand the embodiments of the present application, the following description is first made.

[0174] (1) Mobility History Information (MHI) recording and reporting scheme on the UE side;

[0175] (1.1) Records;

[0176] Mobility history information (also described as UE history information) may include information about one or more cells where the UE resides / accesses, covering three states of the UE (connected, inactive, and idle), and may have multiple entries. The entry records are mainly divided into two situations: an independent entry for each cell information (in coverage) and an independent entry for the situation without coverage (out of coverage).

[0177] For in coverage, when the UE changes to a suitable cell, including from a primary serving cell or a primary serving cell (PCell) of a primary cell group (for connected state) / serving cell (for idle state / inactive state), enters another cell, or enters an out-of-service state (any cell selection) from a normal camped state, the UE records the information of the previous cell as follows:

[0178] Cell identification information: If the Cell Global Identifier (CGI) of the previous PCell / serving cell is available, record the CGI; otherwise, use the frequency point + Physical Cell Identifier (PCI) to identify the cell;

[0179] The length of time the UE stays / accesses the cell (timeSpent).

[0180] For out of coverage, when the UE enters the normal camping state (camped normally) and was previously in the out of service state (any cell selection) or the camping state on any cell (camped on any cell), the UE records the following information:

[0181] An entry only contains the duration information (timeSpent) in the out-of-service state (any cell selection) or any cell camped state (camped on any cell), but no specific cell information record.

[0182] The UE history information maintained by the NR system UE includes records in the idle state, inactive state and connected state. A UE can save up to 16 PCell-related UE history information entries. When the entries stored by the UE reach the upper limit, each time a new entry is written, the oldest entry must be deleted first to ensure that the UE does not exceed the maximum entry limit. For the secondary node (SN), when the UE is in a connected state and has a dual connectivity (DC) connection, the UE records the relevant information of the primary SCG Cell (PSCell) under each PCell cell information. The recorded content is similar to that of the master node (MN), and also includes possible PSCell cell identification information and residence / access time length information, or duration information of the PSCell not connected under the PCell. The total number of PSCell-related entries saved by the UE does not exceed the upper limit of 16.

[0183] (1.2) Report;

[0184] After the UE has the ability to store UE history information and saves the UE history information, the UE can indicate and report it to the network side. During the Radio Resource Control (RRC) (connection) establishment process or RRC (connection) recovery process, the UE can report 1-bit indication information. After the network receives the indication, it can use the UE Information Request / Response message to notify the UE to report and receive the specific historical information content reported by the UE.

[0185] (2) Network-side UE history information (UHI) recording and transmission solution;

[0186] In addition to the historical information recorded on the UE side, the network side also has its own historical information record in the connected state. This record mainly includes the cell ID + time length information that the UE has passed through after entering the connected state, in the form of a list. When the UE has connected state mobility, the source cell will pass the relevant list to the target cell to achieve continuous recording.

[0187] (3) Multicast / Broadcast Service (MBS);

[0188] (3.1)MBS;

[0189] 5G only supports unicast services in REL15 / REL16 versions, and multicast / groupcast / broadcast MBS service types are introduced in REL17. The two methods are:

[0190] Receiving broadcast services (Broadcast MBS): The UE obtains the relevant control channel information (MBS Control Channel, MCCH) of the broadcast service through system information, and then reads the control channel information to obtain multiple broadcast service channel information (MBS Traffic Channel, MTCH), and then receives the corresponding broadcast service on the corresponding MTCH for the service of interest.

[0191] Receiving Multicast MBS: UE receives MBS configuration information based on dedicated signaling and performs MBS multicast service reception according to the configuration information. Multicast MBS can be sent in two ways:

[0192] Point To Multipoint (PTM) mode: The network can control the Multicast MBS service to be transmitted in a point-to-multipoint manner (for example, when the number of UEs receiving the Multicast MBS is sufficient), and the receiving mode is that multiple UEs use the same Group Radio Network Temporary Identifier (G-RNTI) to monitor the MTCH service channel to receive the service;

[0193] Point-to-Point (PTP) mode: The network can control the Multicast MBS service to be transmitted in a point-to-point manner (for example, when the number of UEs receiving the Multicast MBS is small), and the receiving mode is similar to the unicast receiving mode.

[0194] For the reception of Multicast MBS services in PTM mode, only the reception mode in the connected state is supported in REL17, and the reception of Multicast MBS services in PTM mode in the inactive (INACTIVE) state is introduced in REL18. When the UE enters the INACTIVE state, it can continue to receive Multicast MBS services (for example, according to the PTM configuration parameters in the RRC release message). If it then moves to another cell, it can read the MCCH control channel of the new cell according to the control mode of Broadcast MBS, so as to continue to receive related MBS services on the MTCH of the new cell.

[0195] (3.2) MBS mobility;

[0196] For UEs in the RRC_CONNECTED state, the network side makes mobility decisions based on service requirements, cell load, and measurement results reported by the UE. The network side may consider the service continuity of the MBS service. For example, if a base station does not support the MBS service being performed by the UE, the base station will not be given priority as the target base station for the UE to switch to.

[0197] For a non-connected state (including an idle state RRC_IDLE state or an inactive state RRC_INACTIVE state), the UE performs cell reselection according to protocol rules to achieve mobility.

[0198] If the UE is receiving or wishes to receive a Broadcast MBS service and can only receive this Broadcast MBS service by scanning on a frequency providing this service, the UE may regard this frequency as the highest priority during the MBS session as long as certain conditions are met:

[0199] 1) The system information block (SIB) 1 scheduling information of the cell reselected by the UE due to the priority of MBS frequency contains MBS-related SIB20;

[0200] 2) The MBS frequency selection area identity (FSAI) indicated in the SIB21 of the serving cell where the UE is located may correspond to the FSAI in the UE's own user service description (USD); or the frequency is included in the USD of the UE, but the serving cell where the UE is located does not broadcast SIB21 or the broadcast SIB21 does not contain a mapping indication between the frequency and the service.

[0201] On the contrary, if a UE supporting Broadcast MBS is receiving or wishes to receive a Broadcast MBS service, as long as certain conditions are met, the UE may regard the cell reselection candidate frequency where it cannot receive the MBS broadcast service as the lowest priority during the MBS broadcast session.

[0202] (4) Slicing;

[0203] 5G R17 introduces slice-based cell reselection. When a UE supporting slice-based reselection capability receives the UE's desired network slice AS group (NSAG) related information from the UE's NAS layer in the IDLE state or INACTIVE state, the UE combines the slice-related broadcast information provided by the base station in SIB16 or the UE-specific slice-related priority information provided in the RRC release (RRCRelease) message to derive the slice-based cell reselection priority information and perform slice-based cell reselection. The UE will eventually reselect to a cell that supports its most desired NSAG and has the highest priority.

[0204] The UE performs slice-based cell reselection, which mainly includes the following information:

[0205] Slice information from the Non Access Stratum (NAS): the NSAG(s) expected by the UE, the Tracking Area (TA) corresponding to these NSAG(s), and the priority of the NSAG(s) expected by the UE.

[0206] Slice information broadcast by system information (SIB16): In SIB16, the base station broadcasts the frequencies (including serving frequencies and adjacent frequencies) that support slicing and their priorities, the slices supported by each frequency, and a list of cells that support each NSAG on the frequency.

[0207] Slice information provided in the RRC Release message: The base station sends exclusive slice-based frequency priority information to the UE through the RRC Release message, including: the frequencies that support slices, the number of NSAGs supported on each frequency, and the priority of each frequency.

[0208] When the UE receives NSAG(s), the corresponding TA and NSAG priority information from the NAS layer, the UE combines the slice-related information in SIB16 or RRC Release message and derives the slice-based frequency priority according to the following rules:

[0209] The frequencies that support at least one NSAG received from the NAS layer have a higher priority than the frequencies that do not support the NSAG received from the NAS layer;

[0210] Among all frequencies supporting NSAGs received from the NAS layer, the frequency supporting the highest priority NSAG has higher priority;

[0211] Among all frequencies supporting the highest priority NSAG, they are sorted according to the frequency priority field provided in SIB16 or RRC Release message. Frequencies without frequency priority field are prioritized lower than frequencies with frequency priority field provided;

[0212] Frequencies that do not support NSAG are sorted according to the legacy reselection priority.

[0213] After the UE uses the above rules to sort, it performs slice-based cell reselection and finally selects a cell that supports its most desired slice and has the highest frequency priority to reside in.

[0214] Frequency priorities for MBS broadcast and NR sidelink / Vehicle to Everything (V2X) sidelink communications may override slice-based cell reselection priorities.

[0215] When the UE is in a connected state, if the target cell to which the UE switches does not support the slice of the service that the UE is receiving, R18 proposes to use slice remapping to remap the service to a new slice, so as to achieve service continuity.

[0216] (5)NR sidelink / V2X sidelink;

[0217] If the UE is configured to perform both NR sidelink communication and V2X sidelink communication, the UE may consider the frequencies that provide both NR sidelink communication configuration and V2X sidelink communication configuration as the highest priority. If the UE is configured to perform NR sidelink communication without performing V2X communication, the UE may consider the frequencies that provide NR sidelink communication configuration as the highest priority. If the UE is configured to perform V2X sidelink communication without performing NR sidelink communication, the UE may consider the frequencies that provide V2X sidelink communication configuration as the highest priority.

[0218] If the UE is configured to perform NR sidelink communication and V2X sidelink communication simultaneously, but no frequency is found that can provide simultaneous NR sidelink communication configuration and V2X sidelink communication configuration, the UE may consider the frequency that provides either NR sidelink communication configuration or V2X sidelink communication configuration as the highest priority.

[0219] (6) High Speed ​​Dedicated Network (HSDN)

[0220] A HSDN cell is a cell that has a higher priority than other cells when a UE with HSDN capability performs cell reselection in a high mobility state.

[0221] When a UE supporting HSDN capability is in a high mobility state, the UE should always consider HSDN cells as the highest priority (i.e., higher than any other network configured priority). When a UE supporting HSDN is in a non-high mobility state, the UE should always consider HSDN cells as the lowest priority (i.e., lower than any other network configured priority).

[0222] (7) Reduce priority request indication;

[0223] The network can carry a deprioritisationReq configuration to the UE in the RRC Release message;

[0224] When the UE receives this configuration, it will lower the priority of the current frequency or radio access technology (RAT) according to the timer and type in the configuration during the timer operation (T325) (i.e. lower than any network configuration value). The UE shall delete the stored deprioritisation request when receiving a NAS request or performing PLMN / SNPN selection.

[0225] If the UE increases / decreases its priority due to a HSDN cell or a priority reduction request, the UE shall no longer consider the cell reselection priority increase / decrease caused by MBS, NR sidelink / V2X sidelink.

[0226] The current UE historical information records / reports / transmits signal coverage information, and can count the cell identification information and time length of the resident / accessed (PCll and / or PSCell). The historical information records can be used by the network side to determine the UE path, estimate the speed, and make subsequent mobility decisions and optimizations.

[0227] However, for UEs in different states / service transmission situations at different times:

[0228] For example, for a UE that is receiving or wishes to receive an MBS service:

[0229] When the UE is in a connected state, the network may make a different handover decision based on service continuity than when the UE is not receiving MBS services;

[0230] When the UE is in a non-connected state, the cell reselection behavior is also affected by the MBS-related frequency increase / decrease priority, which causes the UE to select a cell that is conducive to MBS service continuity rather than a cell with the best signal reception;

[0231] Alternatively, when the UE is configured to perform NR sidelink communication and V2X sidelink communication simultaneously, or the UE receives the expected NSAG and corresponding priority from the NAS layer, or the UE is in a HSDN cell, or receives a priority reduction request and other different states / service transmissions, the UE may change the frequency / cell priority of the cell reselection based on this information, and the network side may also change the mobility strategy based on this information to move UEs in the same geographical location to different cells. If the cell identification information + connection time are simply recorded in the current existing manner, the network cannot know whether the UE record is related to the different states / service transmission conditions of the UE, and may perform subsequent path decisions / optimizations according to the general switching decision / cell reselection target cell information. However, when the UE is in different states / service transmission conditions, the cell where the UE resides / accesses may be completely different, which affects the accuracy of the network side using the UE historical information for subsequent path decisions / optimizations.

[0232] like Figure 2 As shown, an embodiment of the present application provides an information processing method, which is executed by a terminal, and the method includes:

[0233] Step 201: record mobility history information MHI, where the MHI includes at least one of a first MHI recorded based on first state information of the terminal, a second MHI recorded based on first service information transmitted by the terminal, and a third MHI recorded based on first configuration information of the terminal.

[0236] By reporting the MHI, the network side can learn the actual status / service transmission status of the UE when the UE selects a cell as the target cell for cell reselection, and the principle on which the UE selects the current reselection target cell.

[0275] For another example, if the UE increases / decreases its priority due to a HSDN cell or a priority reduction request, the UE will no longer consider the cell reselection priority increase / decrease caused by MBS, NR sidelink / V2X sidelink.

For example, in the following message, the UHI and / or MHI information can be transmitted between the source base station / target base station in the mobility process, or in the message between the dual-connected MN / SN base stations (some messages only support PSCell historical information content carrying SCG):

[0294] Specific UE path judgment / prediction processing is performed for UEs in various states / service transmission situations (for example, UEs configured for NR sidelink communication and receiving MBS services at the same time).

[0295] Operation 3: Based on the historical information of different UE states / service transmission conditions, generalized UE path judgment / prediction of multiple UE states / service transmission conditions is performed.

[0360] The cell reselection priority information of the second slice information is replaced by the cell reselection priority determined based on the second sidelink information.

[0361] In an embodiment of the present application, the UE / network side, in accordance with relevant rules / strategies, increases / decreases the frequency priority of the UE based on the different states / service transmission conditions of the UE at different times, which will affect the cell reselection of the UE in the IDLE / INACTIVE state or the network mobility decision of the UE in the CONNECTED state. The different states / service transmission conditions of the relevant UE at different times are recorded to assist subsequent UE path judgment / prediction.

[0362] The recording and reporting of the MHI or UHI are described below with reference to an embodiment.

[0363] Embodiment 1: Recording and reporting of MBS-related MHI.

[0364] For a UE in IDLE / INACTIVE state, if the UE is receiving or wishes to receive a Multicast MBS service, and can only receive this Broadcast MBS service by scanning on the frequency providing the service, then as long as certain conditions are met, the UE may regard this frequency as the highest priority during the MBS session; conversely, if a UE supporting Broadcast MBS is receiving or wishes to receive a Broadcast MBS service, then as long as certain conditions are met, the UE may regard the cell reselection candidate frequency at which it cannot receive the MBS broadcast service as the lowest priority during the MBS broadcast session.

[0365] If Figure 4 As shown:

[0366] The UE is at the edge of the cell Cell1, and there are two neighboring cells Cell2 and Cell3 with better signal quality, which belong to different frequencies. The frequency priority of Cell1 broadcast is that the frequency priority of Cell3 is higher than that of Cell1.

[0367] According to the general cell reselection priority rule, the UE will give priority to Cell3 in the cell reselection evaluation. If the signal of Cell3 meets the cell reselection criteria with Cell1, the UE will successfully reselect to Cell3.

[0368] However, if the UE is receiving a broadcast MBS service at this time, and the frequency point where Cell3 is located does not provide the MBS service but the frequency point where Cell2 is located provides the MBS service, the UE can automatically increase the frequency point priority of the frequency point where Cell2 is located, and then reselect to Cell2, so that the UE can continue to receive the service after moving to other cells.

[0369] Based on the UE receiving / not receiving the MBS service, or receiving different MBS services, the optimal frequency point and cell selected by the UE for reselection are different.

[0370] Even if the UE is not receiving an MBS service but is interested in a certain MBS, the above-mentioned MBS priority enhancement mechanism may also be used for the MBS service that the UE is interested in.

[0371] In the R17 version of the 3GPP protocol, the UE can only receive broadcast-type MBS services in the IDLE / INACTIVE state. However, for UEs of R18 and later versions, multicast-type MBS services can be received in the INACTIVE state. The above-mentioned MBS priority enhancement mechanism can also be used for multicast services.

[0372] Therefore, for UE historical information reporting, in addition to the existing reporting frequency cell information and the access time of each cell, MBS related information can be recorded and reported at the same time, for example:

[0373] In the entry for each cell, the first MBS information is recorded for this cell change:

[0374] MBS indication, for example: UE is receiving MBS service / UE is interested in MBS service;

[0375] Priority increase or decrease information, such as an MBS frequency point identifier or an MBS cell identifier whose priority is increased or decreased;

[0376] MBS service type, such as broadcast, multicast;

[0377] MBS service identifier, such as TMGI, G-RNTI or G-CS-RNTI;

[0378] UE RRC status (IDLE / INACTIVE / CONNECTED);

[0379] Whether the UE actually applies the priority increase or decrease information (the UE may decide whether to apply the priority increase / decrease policy based on implementation);

[0380] By reporting the above information, the network side can learn the actual state / service transmission situation of the UE when the UE selects the cell as the target cell for cell reselection, and the principle on which the UE selects the current reselection target cell.

[0381] By reporting this information, the UE path judgment / prediction processed by big data on the network side can obtain more useful information, which is beneficial to the accuracy and precision of the UE path judgment / prediction.

[0382] Another example Figure 5 As shown:

[0383] The network side can know which cells on which frequencies provide which MBS services. Based on the purpose similar to the UE side cell reselection, for the continuity of MBS services, the base station can also implement decision strategies with different priorities for the handover decision of UEs that are currently using MBS services / interested in MBS, such as moving the UE to cell2 with suboptimal signal but can continue the relevant MBS.

[0384] Therefore, for the UE historical information recording on the network side, in addition to the existing recording of frequency cell information and the access time of each cell, MBS related information can also be recorded, for example:

[0385] In the entry for each cell, the second MBS information is recorded for this cell change:

[0386] MBS indication, for example: UE is receiving MBS service / UE is interested in MBS service;

[0387] Priority increase or decrease information, such as an MBS frequency point identifier or an MBS cell identifier whose priority is increased or decreased;

[0388] MBS service identifier, such as TMGI, G-RNTI or G-CS-RNTI;

[0389] Whether the network actually applies the priority increase or decrease information to the UE;

[0390] Through the above information recording, the network side can record the actual state / service transmission situation of the UE when the cell is selected as the switching target cell for the UE, and the principle on which the current target cell is selected for the UE.

[0391] By recording this information, the UE path judgment / prediction of the big data processing on the network side can obtain more useful information, which is beneficial to the accuracy and precision of the UE path judgment / prediction. For example:

[0392] (1) For UE path determination / prediction for big data processing, avoid using one or more of the above-mentioned priority change related information and only use the UE historical information related to general priority as input; or

[0393] (2) Based on the historical information of different UE states / service transmission conditions, UE path judgment / prediction is performed in a detailed and classified manner:

[0394] Performing specific UE path determination / prediction processing for UEs in one of the states / service transmission situations (e.g., UEs receiving MBS services / interested in MBS); or

[0395] Specific UE path judgment / prediction processing is performed for UEs in various states / service transmission situations (for example, UEs configured for NR sidelink communication and receiving MBS services at the same time).

[0396] (3) Based on the historical information of different UE states / service transmission conditions, generalized UE path judgment / prediction of multiple UE states / service transmission conditions is performed.

[0397] Example 2: Recording and reporting of MHI or UHI related to slicing.

[0398] When the UE receives NSAG-related information from the NAS layer, the UE derives the slice-based cell reselection priority based on this information and the NSAG-related information in SIB16 (or RRC Release message), and sets the frequency that supports the UE's most desired slice to the highest priority. The UE will give priority to the cell that supports its most desired slice.

[0399] Therefore, for UE historical information reporting, in addition to the existing reporting frequency cell information and the access time of each cell, slice related information can be recorded and reported at the same time, for example:

[0400] NSAG(s) received by the UE from the NAS layer;

[0401] TA corresponding to NSAG(s);

[0402] The priority level corresponding to the NSAG(s);

[0403] The frequency and supported slice information and cell information supporting the slices and the frequency priority of the slices in the cell broadcast or RRC Release message;

[0404] The slice-based frequency priority finally derived by the UE;

[0405] Through the above reported information, the network side can know how the UE selected the cell as the target cell at that time and on what principle the UE selected the current reselected target cell.

[0406] By reporting this information, the UE path judgment / prediction processed by big data on the network side can obtain more useful information, which is beneficial to the accuracy and precision of the UE path judgment / prediction.

[0407] In addition, the network side can record which cells on which frequencies support slicing. For the continuity of slice services, when the target base station does not support the service that the UE is receiving, the network can remap the slice corresponding to the service that the UE is receiving to a new slice, thereby ensuring the continuity of the slice service.

[0408] Therefore, for the UE historical information record on the network side, in addition to the existing recording of frequency cell information and the access time of each cell, slice related information can also be recorded at the same time, for example:

[0409] In the entry for each cell, record the following for this cell change:

[0410] The UE is receiving services, such as PDU Session;

[0411] The UE is receiving the slice corresponding to the service, such as S-NSSAI;

[0412] The UE is receiving the slice corresponding to the service remapping;

[0413] Slices supported by the target base station and the source base station.

[0414] Embodiment 3: Recording and reporting of MHI or UHI related to Sidelink.

[0415] Similar to Example 1, the UE can increase the cell reselection priority of the relevant frequency points accordingly based on the different NR sidelink / V2X sidelink / NR sidelink+V2X sidelink configuration information sent to the UE by the network, thereby resulting in path records of different cells when the UE is in different states / service transmission conditions.

[0416] Through the UE historical information reported by the UE or recorded by the network itself, the UE path judgment / prediction by big data processing on the network side can obtain more useful information, which is beneficial to the accuracy and precision of the UE path judgment / prediction.

[0417] Embodiment 4: HSDN cell related processing.

[0418] The HSDN information is different from the information in the above embodiments, and is cell-level information. That is, the cell reselection priority based on HSDN. When the UE is in a high mobility state, the non-connected UE (IDLE / INACTIVE) should always regard the HSDN cell as the highest priority (that is, higher than the priority configured by any other network) for cell reselection evaluation; and in order to ensure continuous coverage, the network will also regard the HSDN cell as a high priority for the mobility policy for the connected UE. When the UE supporting HSDN is not in a high mobility state, the HSDN cell is regarded as the lowest priority (that is, lower than the priority configured by any other network).

[0419] Since the HSDN priority cannot be replaced by the MBS-related priority or the sidelink-related priority, when the UE is in multiple states / service transmission situations, the UE / network side can record the actual state / service transmission situation of the current UE and record which priority increase / decrease strategies are actually applied.

[0420] Embodiment 5: Low priority strategy (or reduced priority strategy).

[0421] The network can configure a low priority policy for the UE in the RRC Release message. Similar to the HSDN priority, the priority reduction caused by the low priority policy cannot be replaced by the MBS-related priority or the sidelink-related priority. Therefore, when the UE is in multiple states / service transmission situations, the UE / network side can record the actual state / service transmission situation of the current UE and record which priority increase / decrease policies are actually applied.

[0422] In an embodiment of the present application, the terminal records mobility history information MHI, and the MHI includes at least one of a first MHI recorded based on the first state information of the terminal, a second MHI recorded based on the first service information transmitted by the terminal, and a third MHI recorded based on the first configuration information of the terminal; the MHI is reported so that more useful information can be obtained when the big data on the network side performs UE path judgment / prediction. For example, the network side device can know the actual state / service transmission situation of the UE when the UE selects a certain cell as the target cell for cell reselection, or the principle on which the UE selects the current reselection target cell, thereby facilitating improving the accuracy and precision of the UE path judgment / prediction.
