After being assigned with adaptation layer ID for distal end UE, relaying UE is being forwarded when to the data of base station forwarding distal end UE Data packet in add adaptation layer data packet header, and UE corresponding adaptation layer ID in the distal end is added in the packet header.

Step 604, relaying UE establish request to base station forwarding RRC connection.

It relays UE and establishes addition adaptation layer data packet header in request in the RRC connection, and add this far in the packet header Hold the corresponding adaptation layer ID of UE.After base station receives, parsing is somebody's turn to do, and obtains the adaptation layer ID of distal end UE.For example, through parsing, the message In include UE A S-TMSI (SAE-Temporary Mobile Subscriber Identity, Temporary Mobile Subscriber Identity) And comprising adaptation layer ID a in the packet header of this message, then base station, which would know that, is assigned with adaptation layer ID a for UE A.

So, in the data exchange process between subsequent distal end UE and base station, base station is sent to the lower line number of relaying UE According to the middle adaptation layer ID that need to take distal end UE, UE is relayed when the upstream data of distal end UE is transmitted to base station, also needs to take this far Hold the adaptation layer ID of UE.

As shown in fig. 7, the adaptation layer data packet format transmitted between relaying UE and base station, wherein being 4bit with adaptation layer ID For.

In above process, relaying UE can actively be released to the adaptation layer ID of some distal end UE distribution, or according to base station Some adaptation layer ID is discharged by the instruction that dedicated signaling is sent.If relaying the straight-through Connection Release between UE and distal end UE, Relaying UE can actively be released to the adaptation layer ID of distal end UE.In practical applications, adaptation is assigned with to distal end UE A in relaying UE After layer ID a, if relaying UE releases adaptation layer ID a, it is suitable that relaying UE is believed that distal end UE A was not previously allocated With layer ID, adaptation layer ID a is also not previously allocated.

During distributing adaptation layer ID after UE among the above, relaying UE is in the relay connection for receiving some distal end UE transmission After establishing request, if relaying UE determines that the ID in adaptation layer ID list is all occupied, relaying UE can be to distal end UE It sends for indicating the insufficient instruction of adaptation layer ID.Wherein, which may include the D2D discovery sent in relaying UE In (D2D discovery) message.

Correspondingly, distal end UE can count the number of the instruction received.In distal end, UE receives the number of the instruction After reaching preset value (can be set as needed), if also needing access base station, distal end UE can trigger path gravity treatment, and selection is logical It crosses other suitable relaying UE or access base station is directly attempted by Uu interface.If distal end UE is still needed to by relaying UE access base It stands, then distal end UE will not be selected in the D2D discovery message sent comprising for indicating the instruction of adaptation layer ID deficiency Relay UE.

In the embodiment shown in fig. 8, it is responsible for distributing adaptation layer ID by base station, and the adaptation layer ID of distribution is notified to relay UE.As shown in figure 8, the configuration method of the adaptation layer identification of the embodiment of the present invention, including：

After step 802, base station receive the RRC connection request message of distal end UE, an adaptation layer is distributed for distal end UE ID。

Specifically, base station determines whether to be that the distal end UE is assigned with adaptation layer ID and assignable adaptation layer ID It is whether sufficient.Determining without distributing adaptation layer ID for the distal end UE and when assignable adaptation layer ID abundance, base station according to Request message is established in the RRC connection, distributes adaptation layer ID for the distal end UE.

Step 803, base station send the dedicated signaling of instruction adaptation layer ID to relaying UE, and information wherein included includes：With In the information for the straight-through technology that instruction distal end UE is used, distal end UE is used for straight-through UE ID, adaptation layer ID with relaying UE communication.

Wherein, the dedicated signaling is used to notify the adaptation layer ID for distributing or reassigning for some distal end UE to relaying UE.Since relaying UE is can to distinguish different distal end UE by straight-through technology and straight-through UE ID, so relaying UE can basis The signaling of base station knows the adaptation layer ID wherein carried is allocated to which distal end UE's.
