[0060] In order to perform paging of remote UEs in multi-hop layer 2 U2N relay scenarios, this application provides a paging notification method, apparatus, device and medium.

[0061] Example 1:

[0062] Figure 1 The following is a schematic diagram of a first paging notification process provided in some embodiments of this application, such as... Figure 1 As shown, the process includes the following steps:

[0063] S101: Receive a monitoring paging timing PO request sent by a Layer 2 Type 2 user equipment to a network remote user equipment (L2 U2N Remote UE), wherein the monitoring PO request contains the temporary mobile subscription identifier (5G-S-TMSI) of the L2 U2N Remote UE.

[0064] The paging notification method provided in this application embodiment is applied to Layer 2 (L2) type user equipment to network (UE-to-Network, U2N) relay user equipment (UE). The Layer 2 type user equipment to network relay user equipment can be referred to as L2 U2N relay UE. The L2 U2N relay UE can be connected to the Layer 2 type user equipment to network remote user equipment through the network, etc. The Layer 2 type user equipment to network remote user equipment can be referred to as L2 U2N Remote UE.

[0065] In one possible implementation, when an L2 U2N Remote UE detects a connection to any L2 U2N relay UE, it assumes it is accessing the network via a Layer 2 U2N relay. The L2 U2N Remote UE can then send a paging occupancy (PO) request to the connected L2 U2N relay UE. Optionally, the paging PO request can also be called a request for proxy paging. The paging PO request may include the L2 U2N Remote UE's own temporary mobile subscription identifier (5G S-Temporary Mobile Subscription Identifier, 5G-S-TMSI). Understandably, the L2 U2N relay UE can receive the paging PO request sent by the connected L2 U2N Remote UE and identify the 5G-S-TMSI contained in the paging PO request.

[0066] Optionally, before sending a monitoring PO request to the L2 U2N relay UE connected to it, the L2 U2N Remote UE can also determine whether it is currently in an idle state, which can also be called Radio Resource Control Idle (RRC_IDLE). If the L2 U2N Remote UE recognizes that it is currently in an idle state, it can proceed with the subsequent step of sending a monitoring PO request to the L2 U2N relay UE connected to it.

[0067] S102: Send a monitoring PO request containing the 5G-S-TMSI to the upper-level Layer 2 user equipment to the network relay user equipment (L2 U2N relay UE), so that the monitoring PO request is sent to the L2 U2N relay UE directly connected to the base station, and the L2 U2N relay UE directly connected to the base station listens to the PO corresponding to the 5G-S-TMSI.

[0068] In one possible implementation, in a multi-hop layer 2 U2N relay scenario, the L2 U2N relay UE directly connected to the L2 U2NRemote UE is not the same as the L2 U2N relay UE directly connected to the base station. The L2 U2N relay UE directly connected to the L2 U2N Remote UE does not have the capability to listen for air interface paging. In order to perform paging of remote UEs in a multi-hop layer 2 U2N relay scenario, when the L2 U2N relay UE directly connected to the L2 U2NRemote UE receives a monitoring PO request sent by the L2 U2N Remote UE, it can send the monitoring PO request containing the 5G-S-TMSI of the L2 U2N Remote UE to its superior L2 U2N relay UE.

[0069] Optionally, if the previous-level L2 U2N relay UE is still not a directly connected L2 U2N relay UE to the base station, the previous-level L2 U2N relay UE will again send a monitoring PO request containing 5G-S-TMSI to its next-upper-level L2 U2N relay UE. If the previous-level L2 U2N relay UE is a directly connected L2 U2N relay UE to the base station, the sending will stop. Optionally, if the next-upper-level L2 U2N relay UE is still not a directly connected L2 U2N relay UE to the base station, the next-upper-level L2 U2N relay UE may again send a monitoring PO request containing 5G-S-TMSI to its next-upper-level L2 U2N relay UE. If the next-upper-level L2 U2N relay UE is a directly connected L2 U2N relay UE to the base station, the sending will stop. Optionally, if the next-upper-level L2 U2N relay UE is still not an L2 U2N relay UE directly connected to the base station, then the next-upper-level L2 U2N relay UE can again send a monitoring PO request containing 5G-S-TMSI to its next-upper-level L2 U2N relay UE, and so on. This sending process can be repeated several times until the monitoring PO request is sent to the L2 U2N relay UE directly connected to the base station. This application does not specifically limit the number of times the monitoring PO request is sent. In other words, it does not specifically limit the number of L2 U2N relay UEs contained between the L2 U2N relay UE directly connected to the L2 U2N Remote UE and the L2 U2N relay UE directly connected to the base station. The number of L2 U2N relay UEs contained between these two L2 U2N relay UEs can be 0 or any natural number not less than 1.

[0070] Optionally, before sending the monitoring PO request to its parent L2 U2N relay UE, the L2 U2N relay UE can also determine whether it is currently in an idle state. If the L2 U2N relay UE detects that it is currently in an idle state, it can proceed with the subsequent step of sending the monitoring PO request to its parent L2 U2N relay UE.

[0071] In one possible implementation, after sending a monitoring PO request containing the 5G-S-TMSI to an L2 U2N relay UE directly connected to the base station, the L2 U2N relay UE can monitor the PO corresponding to the 5G-S-TMSI. The L2 U2N relay UE can monitor the PO based on calculation methods such as 5G-S-TMSI mod 1024, which will not be elaborated further here, and this application does not specifically limit the specific monitoring method.

[0072] Optionally, after receiving a monitoring PO request sent by the next-level L2 U2N relay UE, the L2 U2N relay UE directly connected to the base station can determine whether it is currently in an idle state before listening to the PO corresponding to the 5G-S-TMSI contained in the monitoring PO request. If it is identified that it is currently in an idle state, it will proceed with the subsequent steps of listening to the PO corresponding to the 5G-S-TMSI.

[0073] In one possible implementation, when an L2 U2N relay UE directly connected to the base station listens to the PO corresponding to the 5G-S-TMSI, it can add the 5G-S-TMSI to its own listening list. When the base station pagees the L2 U2N Remote UE corresponding to the 5G-S-TMSI, the L2 U2N relay UE directly connected to the base station can receive the corresponding paging notification message. When it determines that the 5G-S-TMSI contained in the paging notification message is in its own listening list, it can send a paging notification message containing the 5G-S-TMSI to the next-level L2 U2N relay UE, thereby sending the paging notification message to the L2 U2N Remote UE corresponding to the 5G-S-TMSI. Sending paging notification messages and sending monitoring PO requests can be considered as two opposite sending processes. The sending links are the same, only the sending directions are opposite. In this application embodiment, the upper-level L2 U2N relay UE and the lower-level L2 U2N relay UE are only for the convenience of describing and distinguishing these two sending processes and sending directions, and are not used to limit specific L2 U2N relay UEs.

[0074] Optionally, the process of sending the paging notification message can be as follows: The L2 U2N relay UE directly connected to the base station sends a paging notification message containing 5G-S-TMSI to the next-level L2 U2N relay UE. If the next-level L2 U2N relay UE is an L2 U2N relay UE directly connected to the L2 U2N Remote UE, then the L2 U2N relay UE directly connected to the L2 U2N Remote UE sends the paging notification message to the L2 U2NRemote UE. Otherwise, if the next-level L2 U2N relay UE is not an L2 U2N relay UE directly connected to the L2 U2N Remote UE, the next-level L2 U2N relay UE can resend the paging notification message to the next-next-level L2 U2N relay UE. Optionally, if the next-lower L2 U2N relay UE is still not directly connected to the L2 U2N Remote UE, then the next-lower L2 U2N relay UE can send the paging notification message to its next-lower L2 U2N relay UE again; if the next-lower L2 U2N relay UE is still not directly connected to the L2 U2N Remote UE, then the next-lower L2 U2N relay UE can send the paging notification message to its next-lower L2 U2N relay UE again, and so on. This process can be repeated several times until the paging notification message is sent to the L2 U2N relay UE directly connected to the L2 U2N Remote UE, and the L2 U2N relay UE directly connected to the L2 U2N Remote UE sends the paging notification message to the L2 U2N Remote UE. This will not be elaborated further here. Optionally, after receiving the paging notification message, the L2 U2N Remote UE may respond to the paging notification message, and this application does not specifically limit this.

[0075] In this embodiment, when the L2 U2N relay UE directly connected to the L2 U2N Remote UE receives a monitoring PO request containing the 5G-S-TMSI of the L2 U2N Remote UE, it can send a monitoring PO request containing the 5G-S-TMSI to the next-level L2 U2N relay UE, so that the monitoring PO request is sent to the L2 U2N relay UE directly connected to the base station, and the L2 U2N relay UE directly connected to the base station can listen to the PO corresponding to the 5G-S-TMSI. Based on this, the purpose of paging the remote UE can be achieved in a multi-hop layer 2 U2N relay scenario.

[0076] Example 2:

[0077] To improve the accuracy of paging remote UEs, based on the above embodiments, in this embodiment, sending a monitoring PO request containing the 5G-S-TMSI to the upper-level Layer 2 Type 2 User Equipment (L2 U2N relay UE), so that the monitoring PO request is sent to the L2 U2N relay UE directly connected to the base station, includes:

[0078] The monitoring PO request and the set multi-hop paging indication are sent together to the next-level L2 U2N relay UE, so that the monitoring PO request and the multi-hop paging indication are sent together to the L2U2N relay UE directly connected to the base station.

[0079] In one possible implementation, considering that in a single-hop Layer 2 U2N relay scenario, there is only one paged node under the PC5 (Proximity Communication) connection, that is, there is a one-to-one relationship between the L2U2N relay UE directly connected to the base station and the paged node, while in a multi-hop Layer 2 U2N relay scenario, there can be multiple paged nodes under the PC5 connection, and the relationship between the L2 U2N relay UE directly connected to the base station and the paged node is no longer one-to-one but one-to-many, an identifier that can indicate the final paged node can be added to the monitoring PO request and paging notification message, etc., to ensure the accuracy of paging the remote UE. Optionally, to improve the accuracy of paging remote UEs, when an L2U2N relay UE sends a monitoring PO request to the next-level L2 U2N relay UE, it can send the monitoring PO request containing (carrying) the 5G-S-TMSI and the multi-hop paging indication together to the next-level L2 U2N relay UE. The next-level L2 U2N relay UE can then send the monitoring PO request containing (carrying) the 5G-S-TMSI and the multi-hop paging indication together to the next-next L2 U2N relay UE, and so on, so that the monitoring PO request and the multi-hop paging indication are sent together to the L2 U2N relay UE directly connected to the base station.

[0080] When each L2 U2N relay UE receives a multi-hop paging indication, it can know that it is currently paging a remote UE in a multi-hop layer 2 U2N relay scenario. When sending monitoring PO requests or paging notification messages to other L2 U2N relay UEs, it can carry this 5G-S-TMSI parameter, so that the L2 U2N Remote UE corresponding to the 5G-S-TMSI can accurately receive the paging notification message, thus maximizing the accuracy of paging remote UEs.

[0081] Optionally, after receiving the paging notification message, if the L2 U2N relay UE directly connected to the base station recognizes that the previously received monitoring PO request containing 5G-S-TMSI corresponds to a multi-hop paging indication, it can be assumed that the corresponding 5G-S-TMSI parameter needs to be carried in the paging notification message at this time, and a paging notification message containing (carrying) 5G-S-TMSI can be sent to the next-level L2 U2N relay UE. This will not be elaborated further here.

[0082] Example 3:

[0083] To improve the accuracy of paging remote UEs, based on the above embodiments, in this embodiment, after the receiving layer 2 user equipment sends a monitoring paging timing (PO) request to the network remote user equipment (L2 U2NRemote UE), the method further includes:

[0084] Identify the identifier of the first connection link between itself and the L2 U2N Remote UE, and save the first correspondence between the 5G-S-TMSI and the identifier of the first connection link.

[0085] In one possible implementation, after receiving a monitoring PO request from an L2 U2N Remote UE, the L2 U2N relay UE can identify the identifier of the connection link (referred to as the first connection link for convenience) between itself and the L2 U2N Remote UE, and save a first correspondence between the 5G-S-TMSI of the L2 U2N Relay UE and the identifier of the first connection link. For example, this first correspondence can be saved in the PC5 context. Subsequently, when sending a paging notification message to the L2 U2N Remote UE corresponding to the 5G-S-TMSI, the identifier of the first connection link carried in the paging notification message can be obtained based on the first correspondence pre-saved in the PC5 context, etc., and then the paging notification message can be sent to the L2 U2N Remote UE corresponding to the 5G-S-TMSI via the connection link corresponding to the identifier of the first connection link.

[0086] Optionally, for each L2 U2N relay UE, after receiving a monitoring PO request from another (next-level) L2 U2N relay UE, it can identify the identifier of the connection link between itself and the L2 U2N relay UE, and save the correspondence between the 5G-S-TMSI and the identifier of the connection link. Subsequently, when receiving a paging notification message from another (previous-level) L2 U2N relay UE, it can obtain the identifier of the connection link corresponding to the 5G-S-TMSI carried in the paging notification message according to the pre-saved correspondence, and send the paging notification message to another (next-level) L2 U2N relay UE or the L2 U2N RemoteUE corresponding to the 5G-S-TMSI through the connection link corresponding to the identifier of the connection link. This will not be elaborated further here.

[0087] Taking an L2 U2N relay UE directly connected to a base station as an example, after receiving a monitoring PO request sent by a next-level L2 U2N relay UE, the L2 U2N relay UE directly connected to the base station can identify the identifier of the connection link (referred to as the second connection link for convenience) between itself and the next-level L2 U2N relay UE, and save the correspondence between the 5G-S-TMSI contained in the monitoring PO request and the identifier of the second connection link (referred to as the second correspondence for convenience). Optionally, when sending a paging notification message containing the 5G-S-TMSI to the next-level L2 U2N relay UE, the L2 U2N relay UE directly connected to the base station can obtain the identifier of the second connection link corresponding to the 5G-S-TMSI according to the pre-saved second correspondence, and then send the paging notification message to the next-level L2 U2N relay UE through the connection link corresponding to the identifier of the second connection link.

[0088] Example 4:

[0089] To ensure the accuracy and security of paging remote UEs, based on the above embodiments, the method in this application embodiment further includes:

[0090] If the connection with the L2 U2N Remote UE is detected to be disconnected, a monitoring PO cancellation request containing the 5G-S-TMSI is sent to the next-level L2 U2N relay UE, so that the monitoring PO cancellation request is sent to the L2 U2N relay UE directly connected to the base station, and the L2U2N relay UE directly connected to the base station cancels the monitoring of the 5G-S-TMSI.

[0091] In one possible implementation, when the L2 U2N Remote UE actively disconnects from the L2 U2N relay UE, or is passively disconnected from the L2 U2N relay UE due to signal or other reasons, the L2 U2N relay UE that was originally directly connected to the L2 U2N Remote UE can detect the disconnection. Upon detecting the disconnection, the L2 U2N relay UE can send a monitoring PO cancellation request containing the 5G-S-TMSI of the L2 U2N Remote UE to the next-level L2 U2N relay UE, thus sending the monitoring PO cancellation request to the L2 U2N relay UE directly connected to the base station. The process of sending the monitoring PO cancellation request to the L2 U2N relay UE directly connected to the base station is similar to the process of sending the monitoring PO request to the L2 U2N relay UE directly connected to the base station. For example, an L2 U2N relay UE can send a monitoring PO cancellation request containing the 5G-S-TMSI of an L2 U2N Remote UE to its upstream L2 U2N relay UE. If the upstream L2 U2N relay UE is still not a directly connected L2 U2N relay UE to the base station, then the upstream L2 U2N relay UE will again send the monitoring PO cancellation request containing the 5G-S-TMSI to its next-upper-level L2 U2N relay UE. If the upstream L2 U2N relay UE is a directly connected L2 U2N relay UE to the base station, then the sending stops. Optionally, if the next-upper-level L2 U2N relay UE is still not a directly connected L2 U2N relay UE to the base station, then the next-upper-level L2 U2N relay UE can again send the monitoring PO cancellation request containing the 5G-S-TMSI to its next-upper-level L2 U2N relay UE. If the next-upper-level L2 U2N relay UE is an L2 U2N relay UE directly connected to the base station, then the transmission stops. Optionally, if the next-upper-level L2 U2N relay UE is still not an L2 U2N relay UE directly connected to the base station, then the next-upper-level L2 U2N relay UE can again send the monitoring PO cancellation request containing 5G-S-TMSI to its next-upper-level L2 U2N relay UE, and so on. This transmission process can be repeated several times until the monitoring PO cancellation request is sent to the L2 U2N relay UE directly connected to the base station. This will not be elaborated further here.

[0092] Optionally, when an L2 U2N relay UE directly connected to the base station receives a monitoring PO cancellation request, it can cancel monitoring of the 5G-S-TMSI.

[0093] Optionally, for each L2 U2N relay UE, after sending a monitoring PO cancellation request containing the 5G-S-TMSI to other L2 U2N relay UEs, if a mapping relationship between the 5G-S-TMSI and the identifier of the connection link was previously saved, this mapping relationship can be deleted. For example, taking an L2 U2N relay UE directly connected to an L2 U2NRemote UE as an example, after sending a monitoring PO cancellation request containing the 5G-S-TMSI to other (upper-level) L2 U2Nrelay UEs, an L2 U2Nrelay UE directly connected to an L2 U2N Remote UE can delete the previously saved first mapping relationship between the 5G-S-TMSI and the identifier of the first connection link.

[0094] Optionally, taking an L2 U2N relay UE directly connected to a base station as an example, after receiving a monitoring PO cancellation request containing a 5G-S-TMSI, the L2 U2N relay UE directly connected to the base station can delete the previously saved second correspondence between the 5G-S-TMSI and the identifier of the second connection link. This will not be elaborated further here.

[0095] For ease of understanding, the paging notification process provided in this application will be explained below through a specific embodiment. (See reference...) Figure 2 , Figure 2 The diagram illustrates a second paging notification process provided in some embodiments of this application, which includes the following steps:

[0096] S201: The L2 U2N Remote UE sends a monitoring PO request to the L2 U2N relay UE directly connected to the L2 U2N Remote UE. The monitoring PO request carries the 5G-S-TMSI of the L2 U2N Remote UE.

[0097] S202: After receiving a monitoring PO request, the L2 U2N relay UE directly connected to the L2 U2N Remote UE will assign the monitoring PO request containing the 5G-S-TMSI and the set multi-hop paging indication to the next-level L2 U2N relay UE, identify the identifier of the first connection link between itself and the L2 U2N Remote UE, and save the first correspondence between the 5G-S-TMSI and the identifier of the first connection link.

[0098] S203: The upstream L2 U2N relay UE of the L2 U2N Remote UE directly connected to the L2 U2N Remote UE is the L2 U2N relay UE directly connected to the base station. The L2 U2N relay UE directly connected to the base station receives monitoring PO requests and multi-hop paging indications sent by the next-level L2 U2N relay UE (the L2 U2N relay UE directly connected to the L2 U2N Remote UE), and listens for the PO corresponding to the 5G-S-TMSI contained in the monitoring PO request. Additionally, it can identify the identifier of the second connection link between itself and the next-level L2 U2N relay UE, and save the second correspondence between the 5G-S-TMSI and the identifier of the second connection link.

[0099] S204: The base station (gNB) initiates paging for the L2 U2N Remote UE corresponding to the 5G-S-TMSI. The paging channel (paging notification message) contains (carries) the 5G-S-TMSI.

[0100] S205: The L2 U2N relay UE directly connected to the base station receives the paging notification message, obtains the identifier of the second connection link corresponding to 5G-S-TMSI according to the pre-saved second correspondence, and sends the paging notification message containing 5G-S-TMSI to the next-level L2 U2N relay UE through the connection link corresponding to the identifier of the second connection link.

[0101] S206: The next-level L2 U2N relay UE directly connected to the base station is the L2 U2N relay UE directly connected to the L2U2NRemote UE. The L2 U2N relay UE directly connected to the L2 U2N Remote UE obtains the identifier of the first connection link corresponding to the 5G-S-TMSI according to the pre-saved first correspondence, and sends the paging notification message to the L2 U2N Remote UE corresponding to the 5G-S-TMSI through the connection link corresponding to the identifier of the first connection link.

[0102] To facilitate understanding, the paging notification process provided in this application will be explained and illustrated below through a specific embodiment. (See reference...) Figure 3 , Figure 3 This illustration shows a third paging notification process provided in some embodiments of this application, which includes the following steps:

[0103] S301: If an L2 U2N relay UE directly connected to an L2 U2N Remote UE detects that the connection with the L2 U2NRemote UE has been lost, it will send a monitoring PO cancellation request containing the 5G-S-TMSI to the next-level L2 U2N relay UE, and delete the first correspondence if it has a first correspondence between the 5G-S-TMSI and the identifier of the first connection link.

[0104] S302: The L2 U2N relay UE directly connected to the L2 U2N Remote UE is the L2 U2N relay UE directly connected to the base station. When the L2 U2N relay UE directly connected to the base station receives a monitoring PO cancellation request sent by the next-level L2 U2N relay UE (the L2 U2N relay UE directly connected to the L2 U2N Remote UE), it cancels the monitoring of 5G-S-TMSI and deletes the second correspondence if it has a second correspondence between 5G-S-TMSI and the identifier of the second connection link.

[0105] To facilitate understanding, the paging notification process provided in this application will be explained and illustrated below through a specific embodiment. (See reference...) Figure 4 , Figure 4 This paper illustrates a fourth paging notification process provided in some embodiments of the present application, which includes the following steps:

[0106] The L2 U2N Remote UE sends a monitoring PO request to the L2 U2N relay UE (referred to as L2 U2N relay UE 1 for ease of description) that is directly connected to the L2 U2N Remote UE. The monitoring PO request carries the 5G-S-TMSI of the L2 U2N Remote UE.

[0107] After receiving the monitoring PO request, L2 U2N relay UE 1 will assign the monitoring PO request containing the 5G-S-TMSI and the set multi-hop paging indication to the next-level L2 U2N relay UE (referred to as L2 U2N relay UE 2 for ease of description), identify the identifier of the first connection link between itself and L2 U2N Remote UE, and save the first correspondence between the 5G-S-TMSI and the identifier of the first connection link.

[0108] After receiving the monitoring PO request, L2 U2N relay UE 2 will send the monitoring PO request containing the 5G-S-TMSI and the set multi-hop paging indication to the next higher level L2 U2N relay UE, identify the identifier of the connection link between itself and L2 U2N relay UE 1, and save the correspondence between the 5G-S-TMSI and the identifier of the connection link.

[0109] The upstream L2 U2N relay UE of L2 U2N relay UE 2 is the L2 U2N relay UE directly connected to the base station. When the L2 U2N relay UE directly connected to the base station receives monitoring PO requests and multi-hop paging instructions from the next-level L2 U2N relay UE (L2U2N relay UE 2), it listens for the PO corresponding to the 5G-S-TMSI contained in the monitoring PO request. Additionally, it can identify the identifier of the second connection link between itself and L2 U2N relay UE 2 and store the second correspondence between the 5G-S-TMSI and the identifier of the second connection link.

[0110] If the base station initiates a paging of the L2 U2N Remote UE corresponding to the 5G-S-TMSI, the paging notification message contains the 5G-S-TMSI. The L2 U2N relay UE directly connected to the base station receives the paging notification message, obtains the identifier of the second connection link corresponding to the 5G-S-TMSI according to the pre-saved second correspondence, and sends the paging notification message containing the 5G-S-TMSI to the L2 U2N relay UE 2 through the connection link corresponding to the identifier of the second connection link.

[0111] L2 U2N relay UE 2 receives the paging notification message, obtains the identifier of the connection link corresponding to the 5G-S-TMSI based on the pre-saved correspondence between the 5G-S-TMSI and the identifier of the connection link, and sends the paging notification message containing the 5G-S-TMSI to L2 U2N relay UE 1 through the connection link corresponding to the identifier of the connection link.

[0112] The L2 U2N relay UE 1 receives the paging notification message, obtains the identifier of the first connection link corresponding to the 5G-S-TMSI according to the pre-saved first correspondence, and sends the paging notification message to the L2 U2N Remote UE corresponding to the 5G-S-TMSI through the connection link corresponding to the identifier of the first connection link.

[0113] To facilitate understanding, the paging notification process provided in this application will be explained and illustrated below through a specific embodiment. Please refer to...Figure 5 , Figure 5 This illustration shows a fifth paging notification process provided in some embodiments of this application, which includes the following steps:

[0114] S501: If L2 U2N relay UE 1, which is directly connected to L2 U2N Remote UE, detects that the connection with L2 U2NRemote UE has been lost, it will send a monitoring PO cancellation request containing 5G-S-TMSI to the next-level L2 U2N relay UE, namely L2U2N relay UE 2, and delete the first correspondence between 5G-S-TMSI and the identifier of the first connection link if it has been stored.

[0115] S502: The L2 U2N relay UE 2 sends a monitoring PO cancellation request containing the 5G-S-TMSI to the upper-level L2U2N relay UE, and deletes the correspondence between the 5G-S-TMSI and the identifier of the connection link if it has been saved.

[0116] S503: The L2 U2N relay UE above L2 U2N relay UE 2 is the L2U2N relay UE directly connected to the base station. When the L2 U2N relay UE directly connected to the base station receives the monitoring PO cancellation request sent by L2 U2N relay UE 2, it cancels the monitoring of 5G-S-TMSI and deletes the second correspondence if it has a second correspondence between 5G-S-TMSI and the identifier of the second connection link.

Figure 6 , Figure 6 This illustration shows a sixth paging notification process provided in some embodiments of this application, which includes the following steps:

[0119] S601: If an L2 U2N relay UE directly connected to the base station receives a monitoring PO request sent by a next-level L2 U2N relay UE, it will listen to the PO corresponding to the 5G-S-TMSI contained in the monitoring PO request.

[0120] S602: Receive a paging notification message, wherein the paging notification message contains the 5G-S-TMSI.

[0121] S603: Send a paging notification message containing the 5G-S-TMSI to the next-level L2 U2Nrelay UE, so that the paging notification message is sent to the L2 U2N Remote UE corresponding to the 5G-S-TMSI.

[0129] The paging notification message is sent to the next-level L2 U2N relay UE through the connection link corresponding to the identifier of the second connection link.

[0130] In one possible implementation, after receiving the paging notification message and before sending the paging notification message containing the 5G-S-TMSI to the next-level L2 U2N relay UE, the method further includes:

[0131] If it is identified that the monitoring PO request corresponds to a multi-hop paging indication, then the subsequent step of sending a paging notification message containing the 5G-S-TMSI to the next-level L2 U2N relay UE is performed.

[0132] In one possible implementation, after receiving the monitoring PO request sent by the next-level L2 U2N relay UE, and before listening to the PO corresponding to the 5G-S-TMSI included in the monitoring PO request, the method further includes:

[0133] If it is detected that it is currently in an idle state, then proceed to the next step of listening to the PO corresponding to the 5G-S-TMSI.

[0134] In one possible implementation, the method further includes:

[0135] If a monitoring PO cancellation request containing the 5G-S-TMSI is received from the next-level L2 U2N relay UE, then the monitoring of the 5G-S-TMSI is cancelled.

[0136] In one possible implementation, the method further includes:

[0137] If a second correspondence exists between the 5G-S-TMSI and the identifier of the second connection link, then the second correspondence is deleted.
