Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the order of execution, and the order of execution of the processes should be determined by the functions and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

In addition, the terms "system" and "network" are often used interchangeably herein.

In the examples provided herein, it should be understood that "B corresponding to a" means that B is associated with a from which B may be determined. It should also be understood that determining B from a does not mean determining B from a alone, but may also determine B from a and/or other information.

As shown in fig. 1, a paging processing method according to an embodiment of the present invention is executed by a first base station, and includes:

step 101, receiving a first paging message to a remote device;

step 102, the first paging message is sent to the remote device in a cell where the first relay device is located;

wherein the first relay device is at least one of:

a relay device reselected by the remote device;

Thus, according to the above steps, after receiving the first paging message for the remote device, the first base station only needs to send the first paging message in the cell in which the relay device reselected by the remote device is located, and/or the first base station recommends that the cell in which the relay device reselected by the remote device is located, without sending the first paging message in all the cells, thereby avoiding the waste of air interface resources.

That is, for the scenario that the remote device (remote UE) reselects to the new relay device 2 (relay UE 2), the relay UE2 is accessed to the network by the first base station, and the first base station may send the received first paging message corresponding to the remote UE only (or preferentially) in the cell where the relay UE2 is located; and when the remote UE enters an inactive/idle state, the first base station recommends a relay UE to be reselected by the remote UE, and the first base station may send the received first paging message corresponding to the remote UE only (or preferentially) to the cell in which the recommends to be reselected. In this way, the first base station does not need to send paging messages to other cells than the cell in which the remote UE is located.

Optionally, before step 102, the method further includes:

the first information includes at least one of:

-a temporary mobile subscriber identity (Temporary Mobile Subscriber Identity, TMSI) of the remote device;

-a radio network temporary identity (Radio Network Tempory Identity, RNTI) of the remote device;

That is, the remote UE reselects to a new relay UE (first relay device), such as relay UE2, at this time, as shown in fig. 2, the relay UE2 is connected to the gcb (first base station) through Uu, a Side Link (SL) between the remote UE and the relay UE1 is released, and SL between the remote UE and the relay UE2 is established; alternatively, as shown in fig. 3, the relay UE2 is connected to the gcb 2 (first base station) at home via Uu, SL between the remote UE and the relay UE1 is released, and SL between the remote UE and the relay UE2 is established. In this scenario, the first base station receives first information of the remote UE sent by the relay UE2, including but not limited to one of the following information: the method comprises the steps of 5G-S-TMSI of a remote UE, I-RNTI of the remote UE, cell ID accessed by the remote UE before entering an idle/inactive state, gNB ID accessed by the remote UE before entering the idle/inactive state, cell ID accessed by a relay UE1 connected to the remote UE before reselection, and gNB ID accessed by a relay UE1 connected to the remote UE before reselection.

Thus, after receiving the first information of the remote UE, the first base station can clearly know that the relay UE that is connected with the remote UE after reselection is the relay UE2 according to the first information. Therefore, after the first base station subsequently receives the paging message sent to the remote UE from the core network or the neighboring base station, the paging message only needs to be sent in the cell where the relay UE2 is located, and does not need to send the paging message in all cells under the registration area (Registration Area, RA) associated with the remote UE.

In this embodiment, the Remote UE establishes a connection with the relay UE2 using a PC5 protocol message (e.g., discovery message), and informs the relay UE2 of the first information of the Remote UE through the message. After receiving the first information of the remote UE, the Relay UE2 forwards the first information of the remote UE to the gNB/gNB2 through uu, where a message carrying the first information may be put into an existing message or a new message is defined. The type of the message carrying the first information may be a radio resource control (Radio Resource Control, RRC) signaling message, or a newly defined medium access control (Media Access Control, MAC) control element (MAC CE). In the case of the MAC CE method, a logical channel ID corresponding to the new MAC CE needs to be defined. The data format of the MAC CE is not described here.

Also, in this embodiment, optionally, after the first base station receives the first information of the remote UE, the method further includes:

sending second information to core network equipment;

In this way, the first base station informs the core network device that the remote UE has completed the relay UE reselection by sending the second information to the core network device. For example, in the above example of reselecting the relay UE2, the second information at least includes the 5G-S-TMSI of the remote UE. The second information is sent to the core network device by the first base station through the NG interface. Of course, the second information sent to the core network may add a new information element to the existing message, or define a new message, which is not described herein.

After the core network device receives the second information, the gcb where the relay UE2 connected to the remote UE is located can be known clearly, so that when the paging message is sent to the remote UE, the paging message only needs to be sent to the gcb where the relay UE2 is located through the NG port, and all gcbs under the registration area associated with the remote UE do not need to be sent. Therefore, optionally, the first paging message is a paging message sent to the first base station by the core network device after receiving the second information.

In this embodiment, optionally, after the first base station receives the first information of the remote UE, the method further includes:

transmitting third information to the second base station;

That is, as shown in fig. 3, after receiving the first information of the remote UE, the first base station (gNB 2) may send third information (such as the I-RNTI of the remote UE, the cell ID or gNB ID where the remote UE1 is connected to before the reselection, etc.) of the remote UE to the second base station (gNB 1) so as to notify the gNB1-remote UE that the remote UE has completed the reselection, where the third information includes at least the I-RNTI of the remote UE. Wherein the third information is sent by the first base station to the home base station of the relay device connected before reselection (relay UE connected before reselection) by the remote UE through the Xn interface.

After receiving the third information, the second base station can clearly know the gNB2 where the relay UE2 connected to the remote UE after reselection is located, so that when the RAN paging (paging) message is sent to the remote UE, the second base station only needs to send the gNB2 where the relay UE2 is located through an Xn port, and does not need to send the paging message to all gnbs under the RAN paging area associated with the remote UE. Therefore, optionally, the first paging message is a paging message forwarded by the second base station corresponding to the remote device after receiving the third information. The above third information sent to the gNB1 may add a new information unit to the existing message, or define a new message, which is not described herein.

Additionally, optionally, before step 102, the method further includes:

That is, when the remote UE enters the inactive/idle state, the first base station may send recommendation information to the remote UE, and recommend to the remote UE a relay UE that may be reselected when the relay UE is reselected later. Thus, when the core network device issues the paging message again to page the remote UE, the NG-RAN can send the paging message preferentially to the cell in which the relay UE recommended to the remote UE is located before, without sending the paging message to all cells in the registration area to which the remote UE belongs.

The recommendation information may be placed in an RRC Release message, and specifically, related relay UE recommendation information may be newly added in the RRC Release message.

If the recommendation information includes a device identifier of the relay device recommending reselection, for example, the recommendation information may use a relay UE ID of the PC5 interface, and may be used to distinguish between different relay UEs recommending.

The reselection priorities of the relay devices that recommend reselection may be different reselection priorities for different relay UEs according to a base station policy (e.g., the base station may refer to the capability of the relay UE and/or the load condition of the current relay UE). The reselection priority may be defined in advance according to information such as the capability of the relay UE, or may be dynamically adjusted according to the condition of the relay UE. The reselection priorities may be divided into two or more, and all the relay UEs (all UEs that may be relay UEs of the remote UE) candidate are classified on different reselection priorities and indicated to the remote UE through an RRC release message.

Of course, in order to enable the first base station to make the recommendation information clear, the instruction of reselecting the relay UE is performed in the RRC release message, and the relay UE needs to indicate the respective relay UE information, that is, the fourth information, to the first base station in advance. Therefore, before the first base station sends the recommendation information to the remote device, the method further comprises:

If a plurality of relay UEs are located in the same base station (first base station), a message from the relay UE to the base station may be newly added in the RRC signaling to send the fourth information. For example, as shown in fig. 4, the relay UE1, the relay UE2, and the relay UE3 are under the same base station, such as NG-RAN, and each of the relay UE1, the relay UE2, and the relay UE3 reports a layer 2 (L2) relay UE ID. And the relay UE3 relays the data of the Remote UE initially, and after the NG-RAN acquires the relay UE ID, the relay UE can be determined to be reselected preferentially for the Remote UE. The NG-RAN determines that the relay UE is reselected preferentially, and then carries indication information in an RRC release message sent to the remote UE, where the indication information is used to indicate the relay UE that is reselected preferentially, and assuming that the relay UE1 is reselected preferentially, the RRC release message includes the relay UE1 (a reselection object preferentially) and the relay UE3 (a connection release object). The remote UE receives the RRC release message, enters RRC idle through Uu, and maintains PC5 CP connection with the relay UE 3. The remote UE receives the PC5 discovery announcement (PC 5 Discovery Announcement) from the Relay UE1, relay UE2, decides to reselect the Relay UE, and learns from the RRC release message that the Relay UE1 is preferentially selected, so the remote UE will send a PC5 discovery request (PC 5 Discovery Solicit) to the Relay UE1 for Relay UE reselection.

In addition, if the multiple relay UEs are under different base stations, the first base station needs to interact relay UE information in advance on the inter-base station interface (Xn interface), that is, fourth information. In this way, when the first base station sends the RRC release message to the remote UE, the first base station may simultaneously carry recommendation information, and recommend the device identifier/reselection priority of the relay UE connected to the other base station.

The device identifier of the relay UE included in the recommendation information and the fourth information may be a relay UE ID defined by the PC5 interface.

As shown in fig. 5, a paging processing method according to an embodiment of the present invention is performed by a third base station, and includes:

step 501, receiving and transmitting a second paging message of a remote device transmitted by a core network device, where the third base station is a home base station of a second relay device;

Here, the core network device sends the second paging message to the remote UE, and the second paging message is sent to the third base station, where the third base station is the home base station of the candidate relay UE of the remote UE, and then the third base station resends the second paging message to the remote UE. The core network device sends the second paging message to the other base station without additional wasted transmission resources. Thus, according to the above step 501, if the third base station is the home base station of the candidate relay UE of the remote UE, the third base station can receive the second paging message sent by the core network device for the remote UE.

It should be understood that, to explicitly send the second paging message to which base stations, the core network device receives the fifth information of the relay device sent by the fourth base station before sending the second paging message; and then determining the second relay equipment and the home base station of the second relay equipment according to the fifth information. Therefore, optionally, the second paging message is a paging message sent to the home base station of the second relay device after the core network device receives the fifth information of the relay device sent by the fourth base station.

Wherein if the fourth base station is NG-RAN, the core network device is an access and mobility management function (Access and Mobility Management Function, AMF) may send the fifth information as the core network device, such as AMF, through a specific message including, but not limited to, a UE context release complete (UE CONTEXT RELEASE COMPLETE) message or a UE context suspension request (UE CONTEXT SUSPEND REQUEST) message.

That is, the fourth base station, such as NG-RAN, can obtain the sixth information as shown above based on its own statistics or reporting by the relay UE and/or the remote UE, thereby determining the fifth information to be transmitted to the core network device. Here, the fourth base station may determine the fifth information when the remote UE is about to enter the idle/inactive state.

Before the remote device enters the RRC idle state or inactive state, identification information of the relay device serving as a relay between the remote device and the base station is obtained through statistics of the fourth base station. When the remote device is in an RRC idle state or inactive state, the identification information of the relay device reselected on the PC5 is obtained through reporting by the relay UE. When the remote equipment is in an RRC connection state, the list of the relay equipment connected under the current service cell or the service node and/or the corresponding connection time length are obtained through statistics of the fourth base station. And when the remote equipment is in an RRC idle state or a non-activated state, the connection time length between the remote equipment and the connected or reselected relay equipment is obtained through reporting by the relay UE. The residence time of the relay device in the current service cell or the service node, the moving speed of the relay device in the current service cell or the service node and the moving direction of the relay device in the current service cell or the service node can be obtained through statistics of the fourth base station. The moving speed of the remote equipment in the current service cell or service node is obtained through statistics of the fourth base station or reporting of relay UE.

Optionally, in this embodiment, the fifth information includes at least one of:

Of course, in the process of sending the second paging message by the core network device, the fifth information may also be sent to the third base station, for example, the AMF sends the fifth information (also referred to as recommended relay device (Recommended Relay UEs for Paging) information for paging) to the NG-RAN through the paging message, so as to help the base station to preferentially select a certain or certain cells to send the second paging message.

For this interface message (including but not limited to UE CONTEXT RELEASE COMPLETE message, UE CONTEXT SUSPEND REQUEST message, and PAGING message), a destination information element is added.

For example, a new target information unit, information on Recommended Relay UEs for Paging information units, is added in the UE CONTEXT RELEASE COMPLETE message, the corresponding presentation (Presence) is "O", and the information unit type and reference (IE type and reference) are "9.3.1.Xx"; a new target information unit, namely Information on Recommended Relay UEs for Paging information unit, is added in the UE CONTEXT SUSPEND REQUEST message, the corresponding presentation (Presence) is "O", and the information unit type and the reference (IE type and reference) are "9.3.1.Xx"; the target information element, assistance Data for Recommended Relay UEs information element, is newly added in the PAGING message, the corresponding presentation (Presence) is "O", and the information element type and reference (IE type and reference) are "9.3.1.Yy". Where "9.3.1.Yy" indicates that this IE provides assistance information for paging in the cell of the recommended relay UE.
