UE as shown in Fig. 3 (a) receives from multiple far-end UE to network relay scene, relaying UE The data of different PC5D2D carryings, when relaying UE forwards these data, need to be mapped to Uu mouth honeycomb It is transmitted in carrying.Same, relaying UE receives honeycomb at Uu mouth and carries the packet sent, as Fruit needs to be transmitted to far-end UE, relaying UE and is also required to consider to be mapped to packet to build between far-end UE It is transmitted in vertical PC5 carrying.It is similar to, UE to the UE relay scene as described in Fig. 3 (b), Relaying UE needs to consider the mapping of the D2D carrying between far-end UE and opposite end far-end UE.

The method proposed by the embodiment of the present invention, possess the UE of relay capabilities can obtain predetermined mapping/ Multiplexing rule (the i.e. first rule), is then mapped to the packet that PC5 interface receives according to described rule Uu carrying forwards, or the packet that Uu mouth receives is mapped to PC5 interface forwards, logical Cross this mode realize relaying carrying control and ensure the purpose of service quality.

The most possible relaying bear control method and relevant signaling process is given below by way of instantiation.

Example 1

User A, B use UE1, the UE2 possessing D2D function respectively.UE1 has been in network coverage shape State, and UE2 is in without the network coverage.The UE1 being in the network coverage is interested in become via node, Relay services is provided, as UE1 is interested in becoming UE-to-network relay for uncovered UE.

If UE1 authorizes by performing D2D relay function, as shown in Figure 4, UE1 can be from ProSe function Or MME receives link deployment information, link deployment information can include carry mapping ruler (i.e. first Rule).At UE1 before ProSe function or MME receives carrying mapping ruler, can be to ProSe Function or MME sends request message, acquisition request carrying mapping ruler.

In addition to the method that Fig. 4 describes, UE1 directly can define with pre-configured mapping ruler or system Relaying UE gives tacit consent to mapping ruler.

Example 2

User A, B use the UE1 possessing D2D function, UE2 respectively.UE1 has been in network coverage shape State, and UE2 is in without the network coverage.The UE1 being in the network coverage is interested in become via node, Relay services is provided for uncovered UE.

Assume that base station configures and activate the UE-to-network relay function of UE1, and UE1 obtains from base station Predefined first rule.Before relaying UE1 performs the mapping of D2D carrying and honeycomb carrying, relaying UE1 needs first to establish D2D carrying and honeycomb carrying.

The foundation of D2D carrying can be to build when relaying UE1 receives the D2D data of far-end UE transmission Vertical corresponding logic channel, RLC receiving entity and PDCP receiving entity.Relaying UE1 is to receiving After D2D data complete MAC/RLC/PDCP process, being delivered to high level, high level can pass through IP packet header purpose Address judges that this packet is intended for relaying UE1 and needs for being transmitted to network.If needing to be forwarded to network, Then whether UE1 can find the EPS carrying that can carry these data according to the first rule judgment, if can not find, Then relaying UE1 initiates carrying foundation/modification process.

Relaying UE1 can also receive far-end UE send for sending UE-to-Network business number According to D2D carrying set up/amendment request time, it is judged that existing EPS carrying these D2D whether can be received to hold Carry corresponding Business Stream and service quality thereof.If cannot meet, then relaying UE1 can initiate EPS carrying Foundation/modification process.If existing EPS carrying can meet requires or relay that the EPS that UE1 initiates holds Carry foundation/amendment to be accepted, then relaying UE1 can accept D2D carrying foundation/amendment that far-end UE sends Request, and initiate D2D carrying foundation/amendment process.

In addition relaying UE1 also can initiate to set up new special when activating UE-to-network relay function Carry in the EPS forwarding far-end UE packet, or existing EPS carrying is revised in request so that it is can Follow-up carrying is from the packet of far-end UE.

The idiographic flow that the carrying that relaying UE1 initiates is set up/revised is as it is shown in figure 5, specifically include that

Step 501, relaying UE1 send bearing resource distribution request/bearing resource amendment ask message to MME, Wherein, the relevant QoS information of the D2D Business Stream from far-end UE of needs polymerization can be comprised and wrapped Filter information.Wherein, QoS information include QCI, priority, whether ensure bit rate, Maximum Bit Rate, Ensure bit rate etc.；Packet filtering information include wish polymerization the IP address of D2D Business Stream, port range, Quality of service class mark, COS, protocol-identifier etc..

If what relaying UE1 wanted to set up is the EPS carrying being exclusively used in and forwarding far-end UE data, then relay UE carries relaying carrying in the bearing resource distribution request/bearing resource amendment request message that MME sends Instruction information forwards the EPS of far-end UE data to carry for setting up to be exclusively used in.Further, bearing resource Distribution request/bearing resource amendment request message may also include relaying relevant information at least one of: it is right to carry Logic Channel Identifier corresponding to the far-end UE priority answered, the priority of communication set, carrying, carrying correspondence Logic channel group mark, priority corresponding to carrying, whether be default bearing etc..

Relaying UE1 receiving D2D data or relaying UE1 startup relay function or can receive D2D Carrying performs step 501 after setting up request.

Step 502, after MME receives this message, sends bearing resource order to SGW/PGW, holds Carry and Resource Commands can include above-mentioned QoS information, packet filtering information and relaying relevant information.

Step 503, SGW/PGW sends to MME and creates carrying request or update bearing request message.

Step 504, after MME receives this message, sending carrying foundation request/bearing modification to base station please Ask, wherein can include the carrying instruction of above-mentioned relaying and relaying relevant information.

Step 505, after base station receives carrying foundation request/bearing modification request, carries out call access control, sentences Whether disconnected interface-free resources can meet demand, if can meet, then base station sends to connect heavily to join to relaying UE1 and disappears Breath, including the Deta bearer newly increased and or amendment data with existing carrying.Reallocation message also can be wrapped Include Non-Access Stratum (NAS, Non-access stratum) information, wherein comprise new foundation carrying or carrying is repaiied QoS, TFT information after changing and relaying relevant information.

Step 506, relaying UE1 completes to connect after heavily joining, and sends to base station to connect and heavily joins completion message.

Step 507, after base station receives this message, sends carrying to MME and sets up the response of response/bearing modification Message.

Step 508, after MME receives this message, sends to SGW/PGW and sets up carrying corresponding message/more New bearer corresponding message.

So far, for forwarding the EPS carrying of far-end UE data set up/to update.This carrying can be exclusively used in Relaying UE1 forwards the data of far-end UE or the EPS identical with the business datum multiplexing of relaying UE1 self Carrying.The D2D packet from far-end UE received can be mapped to these EPS by relaying UE1 afterwards Carrying is sent to network.

Example 3

User A, B use UE1, the UE2 possessing D2D function respectively.UE1 has been in network coverage shape State, and UE2 is in without the network coverage.The UE1 being in the network coverage is interested in become via node, Relay services is provided for uncovered UE.

Assume that base station configures and activate the UE-to-network relay function of UE1, and system is pre-configured holds Carry mapping/multiplexing rule (the i.e. first rule).D2D carrying and the mapping of honeycomb carrying is performed at relaying UE1 Before, relaying UE1 needs first to establish D2D carrying and honeycomb carrying.

UE initiates to set up the flow process of D2D carrying to network trunk, as shown in Figure 6, specifically includes that

Step 601, it is assumed that relaying UE1 honeycomb EPS carrying it has been established that SGW/PGW receive send out Give the packet of relaying UE1, be mapped to corresponding EPS carrying by DL TFT and be sent to relay UE1 Serving BS.

Step 602, after base station receives this packet, is sent to relay UE1 by corresponding Deta bearer.

Step 603, after relaying UE1 receives this packet, according to destination address and the port numbers in IP packet header Judge that being destined to relay UE1 still relays the far-end UE that UE1 accesses.Assume that this packet is destined to The far-end UE2 of relaying UE1 service, then whether relaying UE1 has corresponding D2D according to the first rule judgment Carrying.Without corresponding D2D carrying, then UE1 sets up corresponding logic channel to relaying, RLC sends out Send entity and PDCP sending entity.Further, relaying UE1 can hold to far-end UE transmission D2D Load sets up message, wherein comprises UL TFT corresponding to carrying, QoS information and relaying relevant information (such as figure Shown in middle step 604).After far-end UE2 receives this information, set up D2D according to D2D bearer setup message Carrying, and send D2D carrying set up completion message to relaying UE1 (as shown in step 605 in figure).This Outer relaying UE1 is it is also possible to trigger D2D bearing modification.D2D carrying is set up and D2D amendment process is the most logical Cross D2D connection reallocation message and D2D connection is heavily joined completion message and transmitted.
