[0365] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0366] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0367] In various embodiments of the present invention, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0368] In addition, the terms "system" and "network" are often used interchangeably in this article.

[0369] In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0370] like Figure 1 As shown, a paging processing method according to an embodiment of the present invention is executed by a first base station, including:

[0371] Step 101: Receive the first paging message to the remote device;

[0372] Step 102: Send the first paging message to the remote device in the cell where the first relay device is located;

[0373] The first relay device is at least one of the following:

[0374] The relay device reselected by the remote device;

[0375] The first base station recommends the relay device to be reselected by the remote device.

[0376] Thus, following the steps described above, after receiving the first paging message for the remote device, the first base station only needs to send the first paging message to the cell where the relay device reselected by the remote device is located, and / or the first base station recommends that the cell where the relay device reselected by the remote device is located be sent, without having to send the first paging message to all cells, thus avoiding the waste of air interface resources.

[0377] Specifically, in the scenario where a remote UE reselects a new relay UE2, where relay UE2 is connected to the network by a first base station, the first base station can send the first paging message received for that remote UE only (or preferentially) in the cell where relay UE2 is located. Furthermore, when a remote UE enters an inactive / idle state, the first base station recommends that the remote UE reselect a relay UE. The first base station can then send the first paging message received for that remote UE only (or preferentially) in the cell where the recommended relay UE is located. In this way, the first base station does not need to send paging messages to cells other than the cell where the remote UE is located.

[0378] Optionally, before step 102, the following steps are also included:

[0379] If the first relay device is the relay device reselected by the remote device, the first information of the remote device sent by the first relay device is received.

[0380] The first information is sent by the remote device to the first relay device after establishing a PC5 connection with the first relay device;

[0381] The first information includes at least one of the following:

[0382] The Temporary Mobile Subscriber Identity (TMSI) of the remote device;

[0383] The remote device's Radio Network Temporary Identity (RNTI);

[0384] The identifier of the cell that the remote device accesses before entering the idle or inactive state;

[0385] The identifier of the base station that the remote device accesses before entering the idle or inactive state;

[0386] The identifier of the cell that the remote device accesses before reselecting the relay device;

[0387] The identifier of the base station that the remote device accesses before reselecting the relay device.

[0388] In other words, the remote UE reselects to a new relay UE (the first relay device), such as relay UE2. At this point, if... Figure 2 As shown, relay UE2 connects to its gNB (first base station) via Uu, the side link (SL) between remote UE and relay UE1 is released, and the SL between remote UE and relay UE2 is established; or, as... Figure 3 As shown, relayUE2 connects to its local gNB2 (the first base station) via Uu. The SL between remote UE and relay UE1 is released, and the SL between remote UE and relay UE2 is established. In this scenario, the first base station receives the first information of the remote UE sent by relay UE2. This first information includes, but is not limited to, one of the following: the 5G-S-TMSI of the remote UE, the I-RNTI of the remote UE, the cell ID accessed by the remote UE before entering the idle / inactive state, the gNB ID accessed by the remote UE before entering the idle / inactive state, the cell ID accessed by relay UE1 (where the remote UE is located) before reselection, and the gNB ID accessed by relay UE1 (where the remote UE is located) before reselection.

[0389] Thus, after receiving the first information from this remote UE, the first base station can clearly identify, based on this first information, that the relay UE that established a connection with the remote UE after reselection is relay UE2. Therefore, when the first base station subsequently receives a paging message addressed to this remote UE from the core network or a neighboring base station, it only needs to send this paging message in the cell where relay UE2 is located, without needing to send paging messages in all cells under the Registration Area (RA) associated with the remote UE.

[0390] It should be noted that in this embodiment, the Remote UE establishes a connection with relay UE2 using a PC5 protocol message (e.g., a discovery message) and informs relay UE2 of the Remote UE's first information through this message. After receiving the aforementioned first information from the Remote UE, relay UE2 forwards this first information from the Remote UE to gNB / gNB2 via uu. The message carrying this first information can be placed in an existing message or a new message can be defined. The type of the message carrying this first information can be a Radio Resource Control (RRC) signaling message or a newly defined Media Access Control (MAC) CE. If it is a MAC CE, a new logical channel ID corresponding to the MAC CE also needs to be defined. The data format of the MAC CE will not be described in detail here.

[0391] Furthermore, in this embodiment, optionally, after the first base station receives the first information from the remote UE, it further includes:

[0392] Send the second message to the core network equipment;

[0393] The second information is used to inform the core network device that the remote device has completed the reselection of the relay device, and the second information includes the temporary mobile subscriber identity code of the remote device.

[0394] Thus, the first base station notifies the core network equipment that the remote UE has completed relay UE reselection by sending a second message to the core network equipment. For example, in the example of reselecting relay UE2 above, the second message at least includes the remote UE's 5G-S-TMSI. This second message is sent by the first base station to the core network equipment via the NG interface. Of course, the second message sent to the core network can be modified by adding new information elements to existing messages or defining new messages, which will not be elaborated upon here.

[0395] After receiving the second information, the core network device can clearly identify the gNB where relay UE2, which connects to the remote UE, resides. Therefore, when sending a paging message to the remote UE, it only needs to send it through the NG interface to the gNB where relay UE2 resides, without needing to send paging messages to all gNBs in the registration area associated with the remote UE. Optionally, the first paging message is the paging message sent by the core network device to the first base station after receiving the second information.

[0396] Optionally, in this embodiment, after the first base station receives the first information from the remote UE, it further includes:

[0397] Send the third message to the second base station;

[0398] Wherein, the second base station is the home base station of the relay device previously connected to by the remote device, and the third information is used to inform the second base station that the remote device has completed the reselection of the relay device, and the third information includes the wireless network temporary identifier of the remote device.

[0399] That is, such as Figure 3 As shown, after receiving the first information from the remote UE, the first base station (gNB2) can send third information from the first information (such as the remote UE's I-RNTI, the cell ID or gNB ID of the relay UE1 that the remote UE was connected to before the reselection) to the second base station (gNB1) to notify gNB1-remote UE that relay UE reselection has been completed. The third information includes at least the remote UE's I-RNTI. Specifically, the third information is sent by the first base station via the Xn interface to the home base station of the relay device (the relay UE connected to before the reselection) that the remote UE was connected to before the reselection.

[0400] After receiving the third information, the second base station can clearly identify the gNB2 where relayUE2, which is connected to the remote UE after reselection, resides. Therefore, when sending a RAN paging message to the remote UE, it only needs to send it to the gNB2 where relayUE2 resides via the Xn interface, without needing to send paging messages to all gNBs under the RAN paging area associated with the remote UE. Optionally, the first paging message is the paging message corresponding to the remote device forwarded by the second base station after receiving the third information. The third information sent to gNB1 can be achieved by adding new information elements to existing messages or defining new messages, which will not be elaborated further here.

[0401] Alternatively, before step 102, the following steps may also be included:

[0402] If the first relay device recommends a relay device for the remote device to be reselected by the first base station, and the remote device will enter the RRC idle state or inactive state, the recommendation information is sent to the remote device.

[0403] The recommendation information is used to recommend relay devices for reselection to the remote device.

[0404] In other words, when the remote UE enters the inactive / idle state, the first base station will send recommendation information to the remote UE, recommending a relay UE that can be reselected later during relay UE reselection. This way, when the core network equipment sends paging messages to page the remote UE, NG-RAN can prioritize sending paging messages to the cells where the previously recommended relay UEs reside, without needing to send paging messages to all cells in the remote UE's registered area.

[0405] The recommendation information can be placed in the RRC Release message. Specifically, relevant relay UE recommendation information can be added to the RRC Release message.

[0406] Optionally, the recommendation information includes the device identifier of the relay device to be reselected, and / or the reselection priority of the relay device to be reselected.

[0407] If the recommendation information includes the device identifier of the relay device to be reselected, for example, the recommendation information can use the relay UE ID of the PC5 interface, which can be used to distinguish between different recommended relay UEs.

[0408] The reselection priority of the relay device recommended for reselection can be based on base station policies (such as the base station referencing the relay UE's capabilities and / or current relay UE load), assigning different reselection priorities to different relay UEs. This reselection priority can be predefined based on relay UE capabilities or dynamically adjusted according to the relay UE's situation. Reselection priorities can be divided into two or more categories, and all candidate relay UEs (all UEs that can act as relay UEs for remote UEs) are categorized into different reselection priorities, with indications sent to the remote UEs via RRC release messages.

[0409] Of course, in order for the first base station to clearly understand the recommendation information and indicate the reselection of relay UE in the RRC release message, the relay UE needs to indicate its own relay UE information to the first base station in advance, i.e., the fourth information. Therefore, before the first base station sends the recommendation information to the remote device, it also includes:

[0410] Obtain fourth information from multiple relay devices, the fourth information including the device identifier and / or reselection priority of the relay devices.

[0411] If multiple relay UEs are under the same base station (the first base station), a fourth message can be sent from the relay UE to the base station in the RRC signaling. For example, such as... Figure 4 As shown, relay UE1, relay UE2, and relay UE3 are located under the same base station, such as NG-RAN. Each relay UE1, relay UE2, and relay UE3 reports its Layer 2 (L2) relay UE ID. Initially, relay UE3 relays data from the remote UE. After obtaining the relay UE ID, NG-RAN determines which relay UEs can be preferentially reselected for the remote UE. If NG-RAN determines the relay UE to be preferentially reselected, it will include indication information in the RRC release message sent to the remote UE. This indication information is used to indicate the relay UE to be preferentially reselected. Assuming that relay UE1 is preferentially reselected, the RRC release message includes relay UE1 (preferential reselection target) and relay UE3 (connection release target). Upon receiving the RRC release message, the remote UE enters RRC idle mode via Uu and maintains a PC5 CP connection with relay UE3. When the remote UE receives PC5 Discovery Announcements from relay UE1 and relay UE2, it decides to reselect a relay UE. It learns from the RRC release message that relay UE1 has been selected first, so the remote UE will send a PC5 Discovery Solicit to relay UE1 to reselect a relay UE.

[0412] Furthermore, if multiple relay UEs are located under different base stations, the first base station also needs to exchange relay UE information in advance on the inter-base station interface (Xn interface), i.e., the fourth information. In this way, when the first base station sends an RRC release message to the remote UE, it can also carry recommendation information, recommending the device identifier / reselection priority of relay UEs connected to other base stations.

[0413] Among them, the device identifier of the relay UE included in the recommended information and the fourth information can be the relay UE ID defined by the PC5 interface.

[0414] like Figure 5 As shown, an embodiment of the paging processing method of the present invention is executed by a third base station, including:

[0415] Step 501: If the third base station is the home base station of the second relay device, receive and send the second paging message of the remote device sent by the core network device.

[0416] The second relay device is a candidate relay device for communication between the remote device and the third base station.

[0417] Here, the core network device sends a second paging message to the remote UE by sending the message to a third base station, which is the home base station of the candidate relay UE of the remote UE. The third base station then forwards the message to the remote UE. The core network device does not need to waste transmission resources sending the second paging message to other base stations. Thus, according to step 501 above, when the third base station is the home base station of the candidate relay UE of the remote UE, it can receive the second paging message sent by the core network device for the remote UE.

[0418] It should be understood that, in order to determine which base stations to send the second paging message to, the core network equipment will receive the fifth information of the relay device sent by the fourth base station before sending the second paging message; then, it will determine the second relay device and its home base station based on the fifth information. Therefore, optionally, the second paging message is a paging message sent by the core network equipment to the home base station of the second relay device after receiving the fifth information of the relay device sent by the fourth base station.

[0419] If the fourth base station is NG-RAN, the core network equipment is the Access and Mobility Management Function (AMF). It can send the fifth information to the core network equipment such as the AMF through a specific message. This specific message includes, but is not limited to, the UE CONTEXT RELEASE COMPLETE message or the UE CONTEXT SUSPEND REQUEST message.

[0420] Optionally, the fifth information is determined by the fourth base station based on the sixth information, and the sixth information includes at least one of the following:

[0421] Before the remote device enters the RRC idle state or inactive state, the identification information of the relay device that serves as the relay between the remote device and the base station;

[0422] When the remote device is in RRC idle or inactive state, the identification information of the relay device reselected on PC5;

[0423] When the remote device is in RRC connection state, the list of relay devices that have been connected to under the current serving cell or serving node and / or the corresponding connection duration;

[0424] The connection duration between the remote device and the connected or reselected relay device when the remote device is in RRC idle or inactive state;

[0425] The dwell time of the relay equipment in the current serving cell or serving node;

[0426] The speed at which the relay equipment moves within the current serving cell or serving node;

[0427] The direction of movement of the relay equipment in the current serving cell or serving node;

[0428] The movement speed of the remote device in the current serving cell or serving node.

[0429] That is, the fourth base station, such as NG-RAN, can obtain the sixth information as shown above based on its own statistics or reports from relay UEs and / or remote UEs, thereby determining the fifth information to send to the core network equipment. Here, the fourth base station can determine the fifth information when the remote UE is about to enter the idle / inactive state.

[0430] Before the remote device enters the RRC idle or inactive state, the identification information of the relay device acting as a relay between the remote device and the base station is obtained through statistics from the fourth base station itself. When the remote device is in the RRC idle or inactive state, the identification information of the relay device reselected on PC5 is obtained through reporting by the relay UE. When the remote device is in the RRC connected state, the list of relay devices connected to and / or the corresponding connection duration under the current serving cell or serving node is obtained through statistics from the fourth base station itself. When the remote device is in the RRC idle or inactive state, the connection duration with the connected or reselected relay device is obtained through reporting by the relay UE. The dwell time of the relay device in the current serving cell or serving node, the moving speed of the relay device in the current serving cell or serving node, and the moving direction of the relay device in the current serving cell or serving node can all be obtained through statistics from the fourth base station itself. The moving speed of the remote device in the current serving cell or serving node is obtained through statistics from the fourth base station itself or through reporting by the relay UE.

[0431] Optionally, in this embodiment, the fifth piece of information includes at least one of the following:

[0432] Before the remote device enters the RRC idle state or inactive state, the identification information of the relay device that serves as the relay between the remote device and the base station;

[0433] When the remote device is in RRC idle or inactive state, the identification information of the relay device reselected on PC5;

[0441] The direction of movement of the relay equipment in the current serving cell or serving node.

[0442] Of course, during the process of sending the second paging message, the core network equipment can also send the fifth information to the third base station. For example, the AMF can send the fifth information (also known as Recommended Relay UEs for Paging) to the NG-RAN through the paging message to help the base station prioritize sending the second paging message to one or more cells.

[0443] Optionally, the fifth information is carried in the target information unit of the interface message, and the target information unit is the information unit of the recommended relay device for paging.

[0444] For this interface message (including but not limited to UE CONTEXT RELEASE COMPLETE message, UE CONTEXTSUSPEND REQUEST message, and PAGING message), a new target information element is added.

[0445] For example, a new target information element, "Information on Recommended Relay UEs for Paging," is added to the UE CONTEXT RELEASE COMPLETE message, with a presence of "O" and an IE type and reference of "9.3.1.xx." Similarly, a new target information element, "Information on Recommended Relay UEs for Paging," is added to the UE CONTEXT SUSPEND REQUEST message, with a presence of "O" and an IE type and reference of "9.3.1.xx." Finally, a new target information element, "Assistance Data for Recommended Relay UEs," is added to the PAGING message, with a presence of "O" and an IE type and reference of "9.3.1.yy."

The "9.3.1.xx" indicates that this IE includes a recommended trunk UE for paging.

[0446] After receiving the second paging message, the third base station can distribute the second paging message to all cells, or, further, the fifth information can preferentially select one or more cells to send the paging message. Optionally, the third base station sending the second paging message includes:

[0451] The second relay device is a candidate relay device for communication between the remote device and the third base station.

[0452] According to step 601 above, when the core network device sends a second paging message to the remote UE, it sends the second paging message to the third base station, which is the home base station of the candidate relay UE of the remote UE. Then the third base station sends the message to the remote UE. Therefore, the core network device does not need to waste transmission resources to send the second paging message to other base stations.

[0474] The speed at which the relay equipment moves within the current serving cell or serving node;

[0475] The direction of movement of the relay equipment in the current serving cell or serving node.

[0476] Optionally, the fifth information is carried in the target information unit of the interface message, and the target information unit is the information unit of the recommended relay device for paging.
