Description

Technical Field

[0001] This invention relates to the field of communication technology, and more specifically to a paging method and apparatus for a remote UE, and a computer-readable storage medium. Background Technology

[0002] According to existing protocols, remote user equipment (UE) located outside the coverage area of ​​the serving cell network can transmit signaling and data with the serving cell through a relay UE (or UE-to-Network Relay). For example, the relay UE receives paging messages from the serving cell on behalf of the remote UE and forwards them to the remote UE. When the remote UE is inactive, it needs to listen for paging messages triggered by the core network (CN) and paging messages triggered by the access network (Radio Access Network, RAN).

[0003] In practical applications, UEs may need to receive paging triggered by the core network (CN Paging) and paging triggered by the access network (RAN Paging) at different paging occasions (PO). To address this, the 3rd Generation Partnership Project (3GPP) introduced a paging occasion reuse mechanism (indicated by the ranPagingInIdlePO field in the protocol), allowing UEs to receive paging triggered by the core network (CN Paging) and paging triggered by the access network (RAN Paging) at the paging occasion corresponding to the idle state when inactive.

[0004] However, when a relay UE needs to receive paging from a remote UE that is inactive, and the network applies the new function of paging timing multiplexing, the relay UE using the existing solution will have the problem of not being able to correctly receive paging from the remote UE.

[0039] Compared with the prior art, the technical solution of the embodiments of the present invention has the following beneficial effects:

[0040] For the remote UE side, this embodiment of the invention provides a paging method for the remote UE, including: obtaining the capabilities of the serving cell and the capabilities of the relay user equipment UE, wherein the capabilities include whether paging timing multiplexing is supported; determining paging configuration information according to the capabilities and sending it to the relay UE.

[0041] This implementation scheme better addresses the issue of relay UEs receiving paging messages from inactive remote UEs. Specifically, the remote UE configures appropriate paging configuration information based on whether the relay UE supports paging timing multiplexing and instructs the relay UE accordingly. This allows the relay UE to correctly determine the paging timing corresponding to different paging messages from the remote UE, thereby improving the correct reception rate of remote UE paging messages in relay scenarios. Furthermore, for inactive remote UEs, when the network applies the paging timing multiplexing function, the remote UE ensures that the relay UE correctly receives various types of paging messages from the remote UE sent by the serving cell based on the paging timing multiplexing mechanism by instructing the relay UE with appropriate paging configuration information.

[0042] For the relay UE side, this embodiment of the invention provides a paging method for a remote UE, applied to a relay UE, comprising: receiving paging configuration information from the remote UE, wherein the paging configuration information is determined based on the capabilities of the relay UE and the capabilities of the serving cell, the capabilities including whether paging timing multiplexing is supported; determining a paging timing based on the paging configuration information; and receiving a first paging message and a second paging message from the remote UE at the paging timing.

[0043] This implementation scheme enables correct reception of paging messages from remote UEs. Specifically, since the paging configuration information is specifically configured by the remote UE based on whether the relay UE supports paging timing multiplexing, the relay UE can determine the correct paging timing based on the paging configuration information indicated by the remote UE, and thus receive the paging message from the remote UE at the correct paging timing. For inactive remote UEs, the relay UE determines the correct paging timing for receiving the first paging message and the correct paging timing for receiving the second paging message based on the paging configuration information indicated by the remote UE, and then successfully receives the first and second paging messages at the determined paging timings.

[0052] As mentioned in the background section, when a relay UE needs to receive paging from a remote UE that is inactive, and the network applies the new function of paging timing multiplexing, the relay UE using the existing solution will have the problem of not being able to correctly receive paging from the remote UE.

[0053] Specifically, paging is a common notification method in wireless communication, used to notify the called user equipment (UE), to notify system message updates, or to notify of earthquakes, tsunamis, or other emergencies. The notified UE can be in an idle, inactive, or connected state.

[0054] Paging typically includes paging triggered by the core network (CN) and paging triggered by the access network (RAN). UEs in idle mode need to listen for CN paging, while UEs in inactive mode need to listen for both CN paging and RAN paging.

[0055] When a UE is listening for paging, it needs to determine its paging occupancy (PO) based on its own identifier (5G-S-TMSI (5G-Serving-Temporary Mobile Subscriber Identity) in idle state and I-RNTI (Inactive-Radio Network Temporary Identifier) ​​in inactive state) and other parameters such as the discontinuous reception (DRX) period. The specific method for determining the PO can be found in the relevant provisions of protocol TS38.304.

[0056] In simple terms, when receiving paging triggered by the core network (CN Paging), the UE determines its own paging DRX cycle (denoted as paging cycle T) based on the minimum value among the cell-broadcast default DRX cycle and the non-access stratum configured DRX cycle (i.e., the CN-configured DRX cycle). When receiving paging triggered by the access network (RAN Paging), the UE determines its own paging cycle T based on the minimum value among the cell-broadcast default DRX cycle, the non-access stratum configured DRX cycle, and the RAN-configured DRX cycle (ran-Paging Cycle). Then, based on the paging cycle T and parameters such as the UE's identifier, the timing for receiving the paging (i.e., paging timing PO) is determined.

[0057] For inactive UEs, they need to receive both core network-triggered paging (CN Paging) and access network-triggered paging (RAN Paging) simultaneously. Typically, the network is configured with appropriate parameters to ensure that the UE receives these two paging signals at the same time. However, in actual configurations, there are scenarios where the UE needs to receive CN Paging and RAN Paging at different paging times. This increases the UE's power consumption. To address this, the 3rd Generation Partnership Project (3GPP) introduced a paging timing multiplexing mechanism (indicated by the `ranPagingInIdlePO` field in the protocol).

[0058] For UEs and cells that support paging timing multiplexing, UEs in the inactive state are allowed to use the paging timing corresponding to the idle state. The paging period T used for the paging timing corresponding to the idle state is determined by the minimum value between the default discontinuous reception period broadcast by the cell and the DRX period configured by the non-access stratum. That is, the UE can receive paging triggered by the core network (CN Paging) and paging triggered by the access network side (RAN Paging) in the inactive state using the paging timing corresponding to the idle state.

[0059] On the other hand, New Radio (NR) introduces relays to extend network coverage. A relay is a UE (User Equipment) that performs relay functions. It communicates with the serving cell through the User to Network interface Universal (Uu) interface (Uu port) and with remote UEs through the direct link PC5 interface. With the help of the relay UE, remote UEs located outside the serving cell's network coverage area can transmit signaling and data to the serving cell.

[0060] As mentioned earlier, a remote UE can be located outside the network coverage area. When a relay UE provides service to it, the remote UE can be in an idle state, an inactive state, or a connected state. When the remote UE is in an inactive state, the relay UE needs to listen for paging signals that the network may send to the remote UE. After the network introduces the function of using the paging timing corresponding to the idle state in the inactive state (i.e., the paging timing multiplexing mechanism), how to ensure that the relay UE can correctly receive paging signals from the inactive remote UE from the serving cell is a problem that needs to be solved.

[0061] Regarding the reception of paging messages from inactive remote UEs by a relay UE, the latest approach is for the remote UE to notify the relay UE of the necessary parameters for listening to paging messages, so that the relay UE can determine the timing for receiving paging messages from the remote UE according to the method specified in protocol TS38.304. These necessary parameters may include DRX parameters and the UE's identifier.

[0062] However, the inventors of this application discovered through analysis that the above scheme does not consider the capabilities of the relay UE, such as whether the relay UE supports the function of using the paging timing corresponding to the idle state in the inactive state. This directly leads to the relay UE being unable to correctly receive paging from the remote UE. For example, although both the remote UE and the serving cell support paging timing multiplexing, the relay UE does not support this capability. Therefore, when the serving cell sends core network-triggered paging (CN Paging) and access network-triggered paging (RAN Paging) at the paging timing corresponding to the idle state, the relay UE can only correctly receive the core network-triggered paging (CNPaging). Furthermore, the relay UE may wait for the serving cell to send the remote UE's access network-triggered paging (RAN Paging) at its own derived timing for receiving RAN Paging, which is naturally impossible to achieve.

[0063] To address the aforementioned technical problems, embodiments of the present invention provide a paging method for a remote UE, applicable to a remote UE, comprising: obtaining the capabilities of the serving cell and the capabilities of the relay user equipment UE, wherein the capabilities include whether paging timing multiplexing is supported; determining paging configuration information based on the capabilities and sending it to the relay UE.

[0064] This implementation scheme better addresses the issue of a relay UE receiving paging messages from a remote UE in an inactive state. The relay UE can be in an inactive, idle, or connected state within the serving cell. It provides data and signaling forwarding services to the remote UE via the PC5 interface. Specifically, the remote UE configures appropriate paging configuration information based on whether the relay UE supports paging timing multiplexing and instructs the relay UE accordingly. This allows the relay UE to correctly determine the paging timing corresponding to different paging messages from the remote UE, thereby improving the correct reception rate of remote UE paging messages in relay scenarios. Furthermore, for inactive remote UEs, when the network applies the paging timing multiplexing function, the remote UE ensures that the relay UE correctly receives various paging messages from the remote UE sent by the serving cell based on the paging timing multiplexing mechanism by instructing the relay UE on appropriate paging configuration information.

[0065] To make the above-mentioned objectives, features and beneficial effects of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0066] Figure 1 This is a flowchart of a paging method for a remote UE according to the first embodiment of the present invention.

[0067] This implementation scheme can be applied to the remote UE side, where the remote UE executes this implementation scheme during interaction with the relay UE to receive paging from the serving cell through the relay UE, so as to ensure that the relay UE can correctly receive the paging sent by the serving cell to the remote UE.

[0068] In this implementation scheme, the remote UE can be in an inactive state and needs to receive paging triggered by the core network (CNPaging) (hereinafter referred to as core network paging message) and paging triggered by the access network (RAN paging) (hereinafter referred to as access network paging message). For ease of description, the core network-triggered paging (CNPaging) will be referred to as the first paging message, and the access network-triggered paging (RAN paging) will be referred to as the second paging message.

[0069] In specific implementation, the paging method of the remote UE provided in the following steps S101 to S102 can be executed by a chip with paging function in the user equipment that is the remote UE, or by a baseband chip in the user equipment.

[0070] Specifically, refer to Figure 1 In the first embodiment, the paging method of the remote UE may include the following steps:

[0071] Step S101: Obtain the capabilities of the serving cell and the capabilities of the relay user equipment (UE), wherein the capabilities include whether paging timing multiplexing is supported;

[0072] Step S102: Determine paging configuration information based on the capabilities and send it to the relay UE.

[0073] More specifically, paging timing multiplexing refers to receiving different paging messages at the same paging timing, which can be indicated in signaling using the `ranPagingInIdlePO` field. For example, the paging timing corresponding to the idle state is used in the inactive state. That is, for an inactive UE, the paging timing corresponding to the idle state is multiplexed to simultaneously receive the first paging message and the second paging message. Thus, even when the paging timing of the first paging message and the paging timing of the second paging message do not overlap, the network, by applying the paging timing multiplexing function, enables the remote UE to still receive both types of paging messages simultaneously at a single paging timing.

[0074] In one specific implementation, before step S101, the paging method of this embodiment may further include the step of receiving capability indication information, wherein the capability indication information is used to indicate the capabilities of the serving cell and the relay UE.

[0075] Specifically, the capabilities of the serving cell and the relay UE can be indicated by the same capability indication information.

[0076] For example, the serving cell indicates that it supports paging timing multiplexing (i.e., applies the paging timing multiplexing function) through the first system information block (SIB1). The relay UE indicates whether it supports paging timing multiplexing in the forwarded SIB1 and itself in the same signaling message forwarded to the remote UE.

[0077] Furthermore, the capability indication information can be obtained in advance before executing this implementation scheme and stored in a storage module such as the memory of the remote UE. When executing step S101, the capabilities of the serving cell and the relay UE are obtained from the storage module.

[0078] In one variation, the capabilities of the serving cell and the relay UE can be indicated by different capability indication information. That is, one capability indication information is used to indicate the capabilities of the serving cell, and another capability indication information is used to indicate the capabilities of the relay UE.

[0079] For example, after receiving SIB1 indicating the capabilities of the serving cell from the serving cell, the intermediate UE can forward SIB1 and its own capabilities through different signaling.

[0080] In one specific implementation, a relay UE may only indicate its own capabilities to a remote UE if it supports paging timing multiplexing. Accordingly, if the capability indication information received by the remote UE only indicates that the serving cell supports paging timing multiplexing, it can be determined that the relay UE does not support paging timing multiplexing.

[0081] In one specific implementation, in step S102, appropriate paging parameters can be determined based on whether the serving cell and the relay UE support the paging timing multiplexing function, thereby generating the paging configuration information.

[0082] Specifically, appropriate paging parameters can also be determined by considering the capabilities of the remote UE itself. For example, when both the remote UE and the serving cell support paging timing multiplexing, by reasonably configuring the paging parameters, the generated paging configuration information can ensure that the relay UE receives the second paging message at the paging timing of the first paging message.

[0083] Furthermore, depending on whether the relay UE supports the paging timing multiplexing function, the paging parameters determined by the remote UE also differ. Therefore, regardless of whether the relay UE supports the paging timing multiplexing function, it does not affect the relay UE's ability to receive the second paging message based on the paging timing of the first paging message according to the paging configuration information.

[0084] In a specific implementation, refer to Figure 2If the remote UE, serving cell and relay UE all support paging timing multiplexing, then step S102 may include: step S1021, generating the paging configuration information based at least on the paging parameters associated with the first paging message.

[0085] For example, a remote UE can generate the paging configuration information based solely on the paging parameters associated with the first paging message. By implicitly indicating the remote UE's capabilities by only indicating the paging parameters associated with the first paging message, a relay UE that is unaware of the paging parameters associated with the remote UE's second paging message can recognize that the remote UE supports paging timing multiplexing. This indication method has low signaling overhead.

[0086] For example, the remote UE can generate the paging configuration information based on the paging parameters associated with the first paging message, the paging parameters associated with the second paging message, and the capabilities of the remote UE. In this example, the remote UE indicates all paging parameters used to listen for various types of paging and its own capabilities to the relay UE. The relay UE determines whether paging timing multiplexing needs to be performed based on the capabilities of the remote UE, and receives the first paging message and the second paging message at the paging timing determined according to the paging parameters associated with the first paging message.

[0087] In a specific implementation, continue to refer to Figure 2 If the remote UE and serving cell support paging timing multiplexing, while the relay UE does not support paging timing multiplexing, then step S102 may include: step S1028, assigning the paging parameters associated with the first paging message to the paging parameters associated with the second paging message; step S1029, generating the paging configuration information based on the paging parameters associated with the first paging message and the paging parameters associated with the second paging message.

[0088] Since relay UEs that do not support paging timing multiplexing will still determine the paging timing of the first paging message based on the paging parameters associated with the first paging message and the paging timing of the second paging message based on the paging parameters associated with the second paging message, as per the existing protocol, in this specific implementation, when the remote UE learns that the relay UE does not support paging timing multiplexing, it automatically assigns the paging parameters associated with the first paging message to the paging parameters associated with the second paging message. This ensures that the paging timings of the first and second paging messages calculated by the relay UE based on the relevant information in the paging configuration information are identical. Therefore, even for relay UEs that do not support paging timing multiplexing, this implementation scheme still enables the relay UE to receive the first and second paging messages based on the paging timing of the first paging message multiplexed according to the paging configuration information.

[0089] In one specific implementation, the paging parameters can be selected from: the minimum of the configured DRX period, the configured DRX period, and the default DRX period, as well as the paging period T.

[0090] Specifically, the configured DRX cycle can include the DRX cycle configured by the non-access stratum and the DRX cycle configured by the access network RAN ​​side.

[0091] Furthermore, the default DRX period can include the default DRX period broadcast by the cell (such as the serving cell).

[0092] For example, a remote UE can generate paging configuration information indications to a relay UE based on the configured DRX period.

[0093] For example, a remote UE can indicate the minimum of the configured DRX period and the default DRX period to the relay UE via paging configuration information.

[0094] For example, a remote UE can determine the paging period T based on the minimum of the configured DRX period and the default DRX period, and then indicate the paging period T to the relay UE through paging configuration information.

[0095] In one specific implementation, paging configuration information may include one of the following: the DRX period configured by the non-access stratum; the default DRX period of cell broadcast, the DRX period configured by the non-access stratum; the default DRX period of cell broadcast, the DRX period configured by the non-access stratum, and the DRX period configured by the RAN side; the default DRX period of cell broadcast, the DRX period configured by the non-access stratum, the DRX period configured by the RAN side, and the capabilities of the remote UE; the DRX period configured by the non-access stratum and the capabilities of the remote UE; the DRX period configured by the non-access stratum and the DRX period configured by the RAN side; the DRX period configured by the non-access stratum, the DRX period configured by the RAN side, and the capabilities of the remote UE; the minimum value of the default DRX period of cell broadcast and the DRX period configured by the non-access stratum; the minimum value of the default DRX period of cell broadcast and the DRX period configured by the non-access stratum, and the minimum value among the default DRX period of cell broadcast, the DRX period configured by the non-access stratum, and the DRX period configured by the RAN side; the paging period T; the paging period T and the capabilities of the remote UE.

[0096] Furthermore, paging configuration information may also include other parameters, such as the identifier of the remote UE. For example, the identifier of the remote UE may include the identifier 5G-S-TMSI assigned by the cardinality network and the identifier I-RNTI assigned by the RAN side.

[0097] In one specific implementation, in step S102, paging configuration information can be sent via direct link (PC5) radio resource control (RRC) PC5-RRC signaling.

[0098] In one specific implementation, after step S102, the paging method of this embodiment may further include the steps of: receiving a first paging message and a second paging message, wherein the first paging message and the second paging message are received and forwarded by the relay UE according to the paging configuration information.

[0099] For remote UEs that support paging timing multiplexing, the first paging message and the second paging message are received simultaneously by the relay UE at the paging timing of the first paging message and then forwarded to the remote UE. It should be noted that simultaneous reception here does not mean that CN Paging and RAN Paging can be received simultaneously every time; sometimes only one type of Paging is received, and sometimes no Paging is received.

[0100] For remote UEs that do not support paging timing multiplexing, the first paging message and the second paging message are received by the relay UE at the paging timings of the first paging message and the second paging message, respectively. The relay UE can forward the paging message to the remote UE immediately after receiving a single paging message, or the relay UE can forward the two paging messages together to the remote UE after receiving them.

[0101] Therefore, by adopting this implementation scheme on the remote UE side, the problem of relay UE receiving paging messages from inactive remote UEs can be better solved. Specifically, the remote UE configures appropriate paging configuration information based on whether the relay UE supports paging timing multiplexing and instructs it to the relay UE, so that the relay UE can correctly determine the paging timing corresponding to different paging messages from the remote UE, thereby improving the correct reception rate of remote UE paging messages in relay scenarios. Furthermore, for inactive remote UEs, when the network applies the paging timing multiplexing function, the remote UE ensures that the relay UE correctly receives various types of paging messages from the remote UE sent by the serving cell based on the paging timing multiplexing mechanism by instructing the relay UE with appropriate paging configuration information.

[0102] Figure 3 This is a schematic diagram of a paging device for a remote UE according to a second embodiment of the present invention. Those skilled in the art will understand that the paging device 3 for the remote UE described in this embodiment can be used to implement the above-described... Figure 1 and Figure 2 The method described in the embodiments is a technical solution.

[0103] Specifically, refer to Figure 3The paging device 3 for the remote UE described in this embodiment can be applied to the remote UE and specifically includes: an acquisition module 31, used to acquire the capabilities of the serving cell and the capabilities of the relay UE, wherein the capabilities include whether paging timing multiplexing is supported; and a processing and sending module 32, used to determine paging configuration information according to the capabilities and send it to the relay UE.

[0104] For more information on the working principle and operation mode of the paging device 3 of the remote UE, please refer to the above. Figure 1 and Figure 2 The relevant descriptions in the text will not be repeated here.

[0105] In specific implementation, the paging device 3 of the remote UE mentioned above may correspond to a chip with paging function in the user equipment, or to a chip with data processing function, such as a system-on-a-chip (SOC), baseband chip, etc.; or to a chip module in the user equipment that includes a chip with paging function; or to a chip module with a chip with data processing function, or to the user equipment.

[0106] Figure 4 This is a flowchart of a paging method for a remote UE according to a third embodiment of the present invention.

[0107] This implementation scheme can be applied to the relay UE side, where the relay UE performs the above-mentioned... Figure 1 and Figure 2 The remote UE interacts with the scheme described in the illustrated embodiment to obtain paging configuration information, and determines the correct paging timing based on the paging configuration information to receive the serving cell's paging of the remote UE.

[0108] In this implementation scheme, the relay UE can be in a connected state, an idle state, or an inactive state.

[0109] In this implementation scheme, the relay UE may or may not support the paging timing multiplexing function.

[0110] In specific implementation, the paging method of the remote UE provided in steps S401 to S403 below can be executed by a chip with paging function in the user equipment that acts as a relay UE, or by a baseband chip in the user equipment.

[0111] Specifically, refer to Figure 4 The paging method for the remote UE described in this implementation scheme may include the following steps:

[0112] Step S401: Receive paging configuration information from the remote UE, wherein the paging configuration information is determined based on the capabilities of the relay UE and the serving cell, and the capabilities include whether paging timing multiplexing is supported;

[0113] Step S402: Determine the paging timing based on the paging configuration information;

[0114] Step S403: Receive the first paging message and the second paging message from the remote UE at the paging time.

[0115] Those skilled in the art will understand that steps S401 to S403 can be considered as the above. Figure 1 The execution steps S101 to S102 in the illustrated embodiment correspond to each other, and they are complementary in their specific implementation principles and logic. Therefore, the explanation of the terms involved in this embodiment can be found by referring to... Figure 1 The relevant descriptions of the embodiments shown will not be repeated here.

[0116] Furthermore, the relay UE can learn that the remote UE is inactive through prior interaction with the remote UE; or it can learn that the remote UE is inactive through the serving cell.

[0117] Furthermore, the capabilities of the serving cell can be obtained from the SIB1 sent by the serving cell.

[0118] In one specific implementation, in step S401, the paging configuration information can be received via PC5-RRC signaling.

[0119] In a specific implementation, refer to Figure 5 When the remote UE is in an inactive state, and both the serving cell and the relay UE support paging timing multiplexing, step S402 may include the following steps:

[0120] Step S4021: Determine the capabilities of the remote UE based on the paging configuration information;

[0121] Step S4022: When the remote UE supports paging timing multiplexing, the paging timing of the first paging message is determined according to the paging configuration information.

[0122] Accordingly, step S403 may include: step S4031, receiving the first paging message at the paging time of the first paging message, and reusing the paging time of the first paging message to receive the second paging message.

[0123] For example, the paging configuration information may include the capabilities of the remote UE. Accordingly, the relay UE determines whether the remote UE supports paging timing multiplexing based on the capabilities of the remote UE carried in the paging configuration information.

[0124] For example, when a remote UE supports paging timing multiplexing, it can generate paging configuration information based solely on the paging parameters associated with the first paging message, thereby indicating its capabilities to the relay UE with less signaling overhead. Accordingly, step S4021 may include: when the paging configuration information only includes the paging parameters associated with the first paging message, determining that the remote UE supports paging timing multiplexing.

[0125] In this specific implementation, the relay UE knows that both the serving cell and the remote UE support paging timing multiplexing, and it also supports this function itself. Therefore, it only needs to determine the paging timing of the first paging message, and it can receive the first paging message and the second paging message at that paging timing.

[0126] Furthermore, in response to receiving the first paging message and the second paging message, the relay UE can further perform the following steps: sending the received first paging message and the second paging message to the remote UE. After the relay UE receives the paging message containing the identifier of the remote UE, it sends the received paging message to the remote UE.

[0127] In a specific implementation, continue to refer to Figure 5 When the remote UE is in an inactive state, the serving cell and the remote UE support paging timing multiplexing, while the relay UE does not support paging timing multiplexing, step S402 may include the following steps:

[0128] Step S4028: Determine the paging timing of the first paging message based on the paging parameters associated with the first paging message in the paging configuration information;

[0129] Step S4029: Determine the paging timing of the second paging message based on the paging parameters associated with the second paging message in the paging configuration information, wherein the paging parameters associated with the first paging message are the same as the paging parameters associated with the second paging message.

[0130] Accordingly, step S403 may include: step S4039, receiving the first paging message at the paging time of the first paging message, and receiving the second paging message at the paging time of the second paging message.

[0131] Specifically, when both the serving cell and the remote UE support paging timing multiplexing, but the relay UE itself does not support this function, the relay UE needs to determine the paging timing of the first paging message and the paging timing of the second paging message separately. In this specific implementation, the remote UE sets the paging parameters associated with the second paging message to be the same as those associated with the first paging message (e.g., the paging period T configured on the RAN side can be equal to the paging period T configured on the non-access stratum). Therefore, the paging timings of the two paging messages obtained by the relay UE in steps S4028 and S4029 overlap. Thus, even if the relay UE does not support paging timing multiplexing, it will still receive the first and second paging messages at the correct paging timing (i.e., the paging timing of the first paging message).

[0132] In one specific implementation, the paging parameters can be selected from: the minimum of the configured DRX period, the configured DRX period, and the default DRX period, as well as the paging period T.

[0133] In one specific implementation, the first paging message may include a core network paging message, and the second paging message may include an access network paging message.

[0134] In one specific implementation, prior to step S401, the method of this embodiment may further include the step of: sending capability indication information to the remote UE, wherein the capability indication information is used to indicate the capabilities of the serving cell and / or the relay UE.

[0135] For example, the capabilities of the serving cell and the relay UE can be indicated by different capability indication information.

[0136] For example, the capabilities of the serving cell and the relay UE can be indicated by the same capability indication information.

[0137] In one specific implementation, the method described in this embodiment may further include the step of: if the relay UE does not support paging timing multiplexing, then the capabilities of the serving cell are indicated only in the capability indication information. Thus, its own capabilities can be implicitly indicated to the remote UE in a way with less signaling overhead.

[0138] In one specific implementation, the paging configuration information may include one of the following: a non-access stratum configured DRX period; a default DRX period for cell broadcast, a non-access stratum configured DRX period; a default DRX period for cell broadcast, a non-access stratum configured DRX period, and a RAN-side configured DRX period; a default DRX period for cell broadcast, a non-access stratum configured DRX period, a RAN-side configured DRX period, and the capabilities of the remote UE; a non-access stratum configured DRX period and the capabilities of the remote UE; a non-access stratum configured DRX period and a RAN-side configured DRX period; a non-access stratum configured DRX period, a RAN-side configured DRX period, and the capabilities of the remote UE; the minimum value of the default DRX period for cell broadcast and the non-access stratum configured DRX period; the minimum value of the default DRX period for cell broadcast and the non-access stratum configured DRX period, and the minimum value among the default DRX period for cell broadcast, the non-access stratum configured DRX period, and the RAN-side configured DRX period; a paging period T; and a paging period T and the capabilities of the remote UE.

[0139] Furthermore, paging configuration information may also include other parameters, such as the identifier of the remote UE. For example, the identifier of the remote UE may include the identifier 5G-S-TMSI assigned by the core network and the identifier I-RNTI assigned by the RAN side.

[0140] As described above, by adopting this implementation scheme, the relay UE can correctly receive paging messages from the remote UE. Specifically, since the paging configuration information is specifically configured by the remote UE based on whether the relay UE supports the paging timing multiplexing function, the relay UE can determine the correct paging timing based on the paging configuration information indicated by the remote UE, and then receive the paging message from the remote UE at the correct paging timing. For the inactive remote UE, the relay UE determines the correct paging timing for receiving the first paging message and the correct paging timing for receiving the second paging message based on the paging configuration information indicated by the remote UE, and then successfully receives the first and second paging messages at the determined paging timings.

[0141] Figure 6 This is a schematic diagram of a paging device for a remote UE according to a fourth embodiment of the present invention. Those skilled in the art will understand that the paging device 6 for the remote UE described in this embodiment can be used to implement the above-described... Figure 4 and Figure 5 The method described in the embodiments is a technical solution.

[0142] Specifically, refer to Figure 6The paging device 6 for the remote UE described in this embodiment can be applied to a relay UE, specifically including: a first receiving module 61, used to receive paging configuration information from the remote UE, wherein the paging configuration information is determined according to the capabilities of the relay UE and the capabilities of the serving cell, the capabilities including whether paging timing multiplexing is supported; a processing module 62, used to determine the paging timing according to the paging configuration information; and a second receiving module 63, used to receive the first paging message and the second paging message of the remote UE at the paging timing.

[0143] For more information on the working principle and operation mode of the paging device 6 of the remote UE, please refer to the above. Figure 4 and Figure 5 The relevant descriptions in the text will not be repeated here.

[0144] In specific implementation, the paging device 6 of the remote UE mentioned above may correspond to a chip with paging function in the user equipment, or to a chip with data processing function, such as a system-on-a-chip (SOC), baseband chip, etc.; or to a chip module in the user equipment that includes a chip with paging function; or to a chip module with a chip with data processing function, or to the user equipment.

[0145] In specific implementation, the modules / units included in the various devices and products described in the above embodiments can be software modules / units, hardware modules / units, or a combination of both.

[0146] For example, for various devices and products applied to or integrated into a chip, each module / unit can be implemented using hardware methods such as circuits, or at least some modules / units can be implemented using software programs that run on a processor integrated within the chip, while the remaining (if any) modules / units can be implemented using hardware methods such as circuits; for various devices and products applied to or integrated into a chip module, each module / unit can be implemented using hardware methods such as circuits, and different modules / units can be located in the same component (e.g., chip, circuit module, etc.) or different components of the chip module, or at least some modules / units can be implemented using hardware methods such as circuits. The components can be implemented using software programs that run on the processor integrated within the chip module. The remaining (if any) modules / units can be implemented using hardware methods such as circuits. For various devices and products applied to or integrated into the terminal, each of its components / units can be implemented using hardware methods such as circuits. Different modules / units can be located in the same component (e.g., chip, circuit module, etc.) or in different components within the terminal. Alternatively, at least some modules / units can be implemented using software programs that run on the processor integrated within the terminal, while the remaining (if any) modules / units can be implemented using hardware methods such as circuits.

[0147] In a typical application scenario, refer to Figure 7 In serving cell 71, there is an inactive relay UE 72 that provides services to multiple remote UEs (remote UE 73 and remote UE 74 shown in the figure). Relay UE 72 needs to receive paging messages from the serving cell for the multiple remote UEs it serves, and it also needs to receive its own paging messages.

[0148] In this application scenario, both remote UE73 and remote UE74 are inactive. The serving cell introduces a paging timing reuse function, which indicates the ranPagingInIdlePO field in system message SIB1, indicating support for using the paging timing corresponding to the idle state in the inactive state.

[0149] In the first scenario, assume that the trunk UE72 supports paging timing multiplexing. Combined with... Figure 7 and Figure 8 In this application scenario, the serving cell can perform operation s801 to broadcast system message SIB1, which indicates that the serving cell supports paging timing multiplexing.

[0150] In response to receiving system message SIB1, relay UE 72 can perform operation s802 to forward system message SIB1 to remote UE 73 and remote UE 74. Furthermore, while forwarding system message SIB1, relay UE 72 additionally indicates that it supports paging timing multiplexing. For example, when performing operation s802, relay UE 72 can indicate the forwarded system message SIB1 and its supported capability ranPagingInIdlePO in the same signaling message. Alternatively, when performing operation s802, relay UE 72 can send two capability indication messages to indicate system message SIB1 and ranPagingInIdlePO respectively via different signaling messages.

[0151] Assuming the remote UE 73 supports paging timing multiplexing, in response to receiving system message SIB1 and the relay UE 72's capability, the remote UE 73 recognizes that the serving cell 71 supports paging timing multiplexing. This means that the serving cell 71 will send a paging message to the remote UE 73 using the paging timing determined in the idle state (i.e., the paging timing corresponding to the idle state). At this time, the remote UE 73 can execute operation s803 to send paging configuration information to the relay UE 72. Furthermore, when executing operation s803, the remote UE 73 can only send the paging parameters corresponding to the idle state to the relay UE 72, such as the DRX period configured by the non-access stratum (or send the minimum value of the DRX period configured by the non-access stratum and the default DRX period, or send the paging period T determined based on the minimum value), and the identifier of the remote UE 73 (such as 5G-S-TMSI / I-RNTI).

[0152] In response to receiving paging configuration information, relay UE72 can perform operation s804 to determine the paging timing for receiving potential paging from remote UE73 using the paging parameters provided by remote UE73, and detect paging belonging to remote UE73 at the corresponding paging timing. At this time, even without knowing the paging parameters corresponding to the inactive state of remote UE73 (such as the DRX period configured on the RAN side), relay UE72 can recognize that remote UE73 supports paging timing multiplexing, and thus knows that serving cell 71 will paging remote UE73 at the paging timing corresponding to the paging CN Paging triggered by the core network. Therefore, when relay UE72 performs operation s805 to listen for paging from serving cell 71, it only needs to use the paging parameters corresponding to the idle state indicated by remote UE73 in the paging configuration information to determine the paging timing, and receive paging CN Paging triggered by the core network and paging RAN Paging triggered by the access network side at the determined paging timing.

[0153] In response to receiving a core network-triggered CN Paging and an access network-triggered RAN Paging during the paging timing corresponding to the idle state, the relay UE72 can perform operation s806 to forward the received core network-triggered CN Paging and access network-triggered RAN Paging to the remote UE73.

[0154] Assuming the remote UE74 does not support paging timing multiplexing, under conditions of suboptimal network paging parameter configuration, the remote UE74 needs to listen for paging at different times. In this scenario, the remote UE74 executes operation s803' to send paging configuration information to the relay UE72. The paging configuration information sent by the remote UE74 includes the DRX cycle configured by the non-access stratum and the DRX cycle (ran-PagingCycle) configured by the RAN side (or the minimum value of the DRX cycle configured by the non-access stratum and the default DRX cycle, and the minimum value of the DRX cycle configured by the non-access stratum, the DRX cycle configured by the RAN side, and the default DRX cycle).

[0155] In response to receiving paging configuration information from remote UE74, relay UE72 performs operation s804' to determine the paging timing corresponding to the idle state and the paging timing corresponding to the inactive state of remote UE74, respectively, by using the minimum value of the non-access stratum configured DRX period and the default DRX period, and the minimum value of the non-access stratum configured DRX period, the RAN-side configured DRX period, and the default DRX period. Then, relay UE72 can perform operation s8051' to receive core network-triggered CN paging sent by the serving cell at the paging timing corresponding to the idle state. Relay UE72 can also perform operation s8052' to receive access network-triggered RAN paging sent by the serving cell at the paging timing corresponding to the inactive state.

[0156] Finally, the relay UE72 can perform operation s806' to forward the received core network-triggered paging (CN Paging) and access network-triggered RAN Paging to the remote UE74.

[0157] In the second scenario, assume that the trunk UE72 does not support paging timing multiplexing. Combined with... Figure 7 and Figure 9 In this application scenario, the serving cell can perform operation s901 to broadcast system message SIB1, which indicates that the serving cell supports paging timing multiplexing.

[0158] In response to receiving system message SIB1, relay UE72 can perform operation s902 to forward system message SIB1 to remote UE73 and remote UE74. Since relay UE72 does not support paging timing multiplexing, it does not indicate that it supports ranPagingInIdlePO when forwarding system message SIB1 to remote UE73 and remote UE74.

[0159] Assuming the remote UE 73 supports paging timing multiplexing, in response to receiving system message SIB1, the remote UE 73 recognizes that the serving cell 71 will send a paging message to the remote UE 73 using the paging timing determined by the idle state method. At this time, the remote UE 73 can perform operation s903 to set the same size non-access stratum configured DRX cycle (nasPagingCycle) and RAN configured DRX cycle (ranPagingCycle) in the PC5 interface, and set the RAN configured DRX cycle (ranPagingCycle) to the same value as the non-access stratum configured DRX cycle (nasPagingCycle).

[0160] Then, the remote UE73 can perform operation s904 to send paging configuration information to the relay UE72. When performing operation s904, the paging configuration information sent by the remote UE73 may include the DRX period configured by the non-access stratum (or the minimum of the DRX period configured by the non-access stratum and the default DRX period, or a paging period T determined based on the minimum value), the DRX period of the RAN layer (or the minimum of the DRX period configured by the non-access stratum, the DRX period configured by the RAN side, and the default DRX period, or a paging period T determined based on the minimum value), and the identifier of the remote UE73.

[0161] In response to receiving paging configuration information and determining that the remote UE73 is in an inactive state based on I-RNTI, the relay UE72 can perform operation s905 to determine the paging timing corresponding to the idle state and the paging timing corresponding to the inactive state of the remote UE73 by using the minimum value of the DRX period configured by the non-access stratum and the default DRX period, as well as the minimum value of the DRX period configured by the non-access stratum, the DRX period configured by the RAN side, and the default DRX period.

[0162] In this scenario, since the remote UE73 has pre-assigned the non-access stratum configured DRX cycle (nasPagingCycle) to the RAN-configured DRX cycle (ranPagingCycle) on the PC5 interface, the paging timing corresponding to the idle state determined by operation s905 still overlaps with the paging timing corresponding to the inactive state. Therefore, when the relay UE72 performs operation s906 to listen for paging from the serving cell 71, it actually still receives both the core network-triggered CN Paging and the access network-triggered RAN Paging simultaneously during the paging timing corresponding to the idle state. The paging may contain the identifier of the remote UE73.

[0163] In response to receiving a core network-triggered CN Paging and an access network-triggered RAN Paging, the relay UE72 can perform operation s907 to forward the received core network-triggered CN Paging and access network-triggered RAN Paging to the remote UE73.

[0164] Assuming that the remote UE74 does not support paging timing multiplexing, when the remote UE74 realizes that the paging timing corresponding to the idle state and the paging timing corresponding to the inactive state may be different, the remote UE74 executes operation s904' to send paging configuration information to the relay UE72. The paging configuration information sent by the remote UE74 includes the DRX cycle configured by the non-access stratum and the DRX cycle configured by the RAN side (ran-PagingCycle) (or the minimum value of the DRX cycle configured by the non-access stratum and the default DRX cycle, and the minimum value of the DRX cycle configured by the non-access stratum, the DRX cycle configured by the RAN side, and the default DRX cycle).

[0165] In response to receiving paging configuration information from remote UE74, relay UE72 performs operation s905' to determine the paging timing corresponding to the idle state and the paging timing corresponding to the inactive state of remote UE74, respectively, by using the minimum value of the non-access stratum configured DRX period and the default DRX period, and the minimum value of the non-access stratum configured DRX period, the RAN-side configured DRX period, and the default DRX period. Then, relay UE72 can perform operation s9061' to receive core network-triggered paging (CN Paging) from the serving cell, which may contain the identifier of remote UE74, during the paging timing corresponding to the idle state. Relay UE72 can also perform operation s9062' to receive access network-triggered paging (RAN Paging) from the serving cell, which may contain the identifier of remote UE74, during the paging timing corresponding to the inactive state.

[0166] Finally, the relay UE72 can perform operation s907' to forward the received core network-triggered paging (CN Paging) and access network-triggered RAN Paging to the remote UE74. If the paging contains the identifier of the remote UE74, the relay UE72 sends the received paging to the remote UE74.

[0167] This invention also provides a computer-readable storage medium, which is a non-volatile or non-transitory storage medium storing a computer program.
