The term herein “and/or” is only an association relationship to describe associated objects, meaning that there may be three kinds of relationships, for example, A and/or B may mean three cases where: A exists alone, both A and B exist, and B exists alone. In addition, a character “/” herein generally means that related objects before and after “/” are in an “or” relationship.

In some scenarios, a layer 2-based UE-to-Network relay UE is introduced, and the UE-to-Network relay UE may connect directly to the network. In some embodiments, the remote terminal is connected to an access network (e.g., gNB) and a core network (CN) (e.g., 5GC) via the UE-to-Network relay UE.
As shown in
In some embodiments, the link between the relay UE and the network may be called a Uu link, a Uu path; a direct link between the remote UE and the network may also be called a Uu link, a Uu path; and the link between the remote UE and the relay UE may be called a PC5 link, a PC5 path.
The adaptation layer of the relay UE supports uplink bearer mapping between access PC5 RLC channels, which is used to perform the transmission and reception of Uu channel on the Uu path between the relay UE and the network. For relay services of the uplink, different end-to-end bearers (e.g., signaling radio bearers (SRBs)), data radio bearers (DRBs)) of the same remote UE and/or different remote UEs may be mapped with N:1 and be data-multiplexed on a Uu RLC channel.
The adaptation layer of the relay UE includes identification information of the remote terminal of an uplink service to be relayed and identification information of a radio bearer of the remote terminal, so that the gNB correlates the received data packets of a specific packet data convergence protocol (PDCP) entity associated with the radio bearer of the remote terminal.
The adaptation layer of the relay UE may be used to support downlink bearer mapping at the gNB, to map an end-to-end radio bearer (e.g., SRB, DRB) of the remote terminal to a Uu RLC channel via the Uu path between the relay UE and the network. The adaptation layer of the relay UE may be used to support downlink N:1 bearer mapping and data multiplexing between multiple end-to-end radio bearers (e.g., SRBs, DRBs) of the remote UE and/or different remote UEs and a Uu RLC channel on the Uu path between the relay UE and the network.
The adaptation layer of the relay UE includes identification information of the remote terminal of the downlink service to be relayed. The identification information of the radio bearer of the remote terminal and the identification information of the remote terminal need to be placed in the adaptation layer of the relay UE by the gNB, so that the relay UE maps the data packet received from the radio bearer of the remote terminal to the PC5 RLC channel associated with the radio bearer.
In some scenarios, the remote UE may be connected to the network via multiple paths, for example, the multiple paths include a direct path between the remote UE and the network, and a relay path that connects to the network via the relay UE.
For example, as shown in
In the related art, the connection between the remote UE and the relay UE is based on an interface defined by the 3rd generation partnership project (3GPP) protocol, such as the PC5 interface.
In actual applications, the remote UE and the relay UE may also be connected by using an interface defined by a non-3GPP protocol, such as a wired connection, a wireless local area network (Wireless LAN, WLAN) connection, a blue tooth (Blue Tooth, BT) connection, etc.
Therefore, in a multi-path relay system based on the interface defined by the non-3GPP protocol, how to perform connection management is an urgent problem to be solved.

Those ordinary skilled in the art may realize that units and algorithm steps of the examples described in combination with the embodiments disclosed herein can be implemented in electronic hardware or in a combination of computer software and electronic hardware. Whether these functions are performed by way of hardware or software depends on an application and a design constraint of the technical solution. A skilled person may use different methods for each application, to implement the described functions, but such implementation should not be considered beyond the scope of the present application.
It may be clearly understood by those skilled in the art that, for convenience and brevity of the description, the working procedures of the system, the apparatus and the unit described above may refer to the corresponding procedures in the above method embodiments, which will not be repeated here.
In the several embodiments provided by the application, it should be understood that, the disclosed systems, apparatus, and method may be implemented in other ways. For example, the apparatus embodiments described above are only schematic, for example, division of the units is only division of logical functions, and there may be other division methods in an actual implementation, for example, a plurality of units or components may be combined or integrated into another system, or some features may be ignored or not performed. On the other hand, the coupling or direct coupling or communicative connection between each other as shown or discussed may be indirect coupling or communicative connection of apparatus or units via some interfaces, which may be electrical, mechanical, or in other forms.
The units illustrated as separate components may be or may not be physically separated, and the components shown as units may be or may not be physical units, that is, they may be located in one place, or may be distributed onto a plurality of network units. A part or all of the units may be selected according to actual needs, to implement the purpose of the schemes of the embodiments.
In addition, the various functional units in the various embodiments of the present application may be integrated into one processing unit, or the various units may exist physically separately, or two or more units may be integrated into one unit.
If the described functions are implemented in the form of a software functional unit and sold or used as an independent product, they may be stored in a non-transitory computer-readable storage medium. Based on this understanding, the technical solution of the present application essentially, or a part of the technical solution that contributes to the prior art, or a part of the technical solution, may be embodied in the form of a software product, and the computer software product is stored in a storage medium, and includes a plurality of instructions for enabling a computer device (which may be a personal computer, a server, or a network device, etc.) to perform all or some of steps of the methods described in the various embodiments of the present application. And, the storage medium mentioned above includes a USB flash drive (U disk), a mobile hard disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), a diskette, or an optical disk, and various mediums that may store program codes.
The above content is merely exemplary implementations of the present application, but the protection scope of the present application is not limited thereto, and any skilled familiar with this technical field may easily think of changes or substitutions within the technical scope disclosed in the present application, which should be all covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
This application is a Continuation application of International Application No. PCT/CN2022/084570 filed on Mar. 31, 2022, which is incorporated herein by reference in its entirety.
