Following embodiment technical problems to be solved are how to support that relaying UE forwardings distal end UE (includes but not limited to that can wear Wear/eMTC/NB-IoT equipment (w-UE)) the carrying configurations of data and problem of management.The method proposed by following embodiment, far It holds UE to establish with relaying UE to communicate to connect, and carries out negotiation configuration and the Uu of the PC5 carryings of relaying UE forwarding distal end UE data Carrying configuration communicates to ensure that distal end UE is smoothed out by relaying UE with network.It should be noted that in following instance with It is illustrated for wearable UE (w-UE), and r-UE or relay UE is used to indicate relaying UE in the following example.

Example 1

The data that this example provides the wearable/eMTC/NB-IoT UE of one kind are forwarded by relaying UE under scene, and forwarding is held It carries configuration and establishes related procedure, as shown in Figure 8.In this example, w-UE is in and normally covers or spread over down, can with eNB Directly to carry out Signalling exchange, the problems such as considering cost and economize on electricity, relaying r-UE is found, data are forwarded by r-UE, reaches and subtracts The purpose of low power consumption, relaying r-UE are in connected state, and w-UE and r-UE is under the covering of same base station.

Step 0:Relay is found and selection.R13 ProSe UE-to-network relay have found flow, support two kinds Relay discovery modes, relay broadcast discovery messages, w-UE is monitored or w-UE sends discovery solicitation and disappears Breath, relay responses.W-UE independently selects relay according to link-quality, the signal strength etc. between r-UE, and will be selected Relay reports eNB.

Step 1:When w-UE has data to send or network has data to w-UE, the EPS carryings of w-UE or PGW initiations w-UE It establishes.The EPS loading establishing process of w-UE is tradition LTE flows, is industry knowledge, which is not described herein again.

Step 2:When the EPS carryings that w-UE or PGW initiates w-UE are established, and eNB is that w-UE configures corresponding Uu mouthfuls of DRB, ENB can be that EPS carryings configure corresponding PC5 carryings simultaneously.It includes following arbitrary combination that configuration information is established in PC5 carryings: PC5 load identifications, pdcp configurations, rlc configurations, Logic Channel Identifier, logic channel configuration, PC5 carry QoS information;Wherein, Rlc configurations include following arbitrary combination:Poll retransmission timer (t-PollRetransmit), polling protocol data cell (pollPDU), poll byte number (pollByte), maximum retransmission threshold value (maxRetxThreshold), reorder timer (t- Reordering), Status Disable timer (t-StatusProhibit), Unacknowledged Mode serial number field grow (sn- FieldLength);Logic channel configures:Logic channel group LCG, preferential ensures bit rate PBR, bucket size duration BSD;It includes following arbitrary combination that PC5, which carries QoS information,:Service quality rating QCI ensures bit rate GBR, maximal bit speed Rate MBR, UE Aggregate Maximum Bit Rate (UE-AMBR).PC5 carries the PC5 load identifications established in configuration information, logic channel Mark, logic channel group can be multiplexed Uu DRB marks, Logic Channel Identifier, the logic channel group of corresponding EPS carryings, if It is not multiplexed, then EPS load identifications, Uu DRB marks comprising corresponding EPS carryings in configuration information are established in PC5 carryings.PC5 is carried Configuration information is sent to w-UE by RRC reallocation messages.Optionally, it includes to be initiated to relay UE that PC5, which is carried in configuration information, The instruction information that PC5 carryings are established.And after the completion of PC5 is carried and established (i.e. after the completion of step 4), w-UE sends RRC weights to eNB Completion is established with message instruction PC5 carryings are completed.

Step 3:W-UE carries out safe floor 2 with selected r-UE and connect, and w-UE sends direct communication request to r-UE and takes Band ProSe UE ID, r-UE responses.Direct communication request and response message can be multiplexed the PC5Signalling of R13 Protocol message (NAS message), or pass through PC5AS signaling message, it is meant that PC5 chain of command agreement stack can increase class Like the protocol layer of RRC.

Step 4:PC5 carries configuration interactive and carrying is established.W-UE sends PC5 carryings to r-UE and establishes message, carry from Configuration information and corresponding PC5 carrying QoS informations are established in the PC5 carryings that eNB is received, and r-UE sends response message, and completes PC5 Carrying configuration.Related news are established in connection in similar step 3, and PC5 carryings are established and response message can also be PC5NAS letters Enable message or PC5AS signaling messages.

Step 5:R-UE receive w-UE PC5 carrying establish message after, can to w-UE carry out admission control.R-UE according to The carrying QoS informations of the PC5 in configuration information and the established PC5 carryings of r-UE are established in the PC5 carryings that the w-UE received is sent Quantity, resource load condition, it is determined whether receive and establish new PC5 carryings;Or PC5 carryings QoS information is sent to base by r-UE It stands, base station determines whether that r-UE receivings are established the PC5 and carried according to scheduling of resource/distribution condition.R-UE is allowing to receive Transmission PC5 carryings establish response message to w-UE after establishing PC5 carryings.

Step 6:After message is established in the PC5 carryings for receiving w-UE and PC5 carryings are established in receiving, r-UE judges whether r-UE It needs to establish the EPS carryings for being exclusively used in forwarding w-UE data, configuration is established in the PC5 carryings that r-UE is sent according to the w-UE received In information PC5 carrying QoS information and r-UE safeguarded EPS carrying list information, it is determined whether have meet the requirements it is special In forwarding w-UE data EPS carrying, if it is not, r-UE to network originated traffic ask, bearing resource distribution request or Bearing resource modification request, is established or modification is exclusively used in forwarding the EPS carryings of w-UE data, and it is to pass which, which carries Establishing process, System LTE flows, which is not described herein again.

Step 7:R-UE is after establishing the EPS carryings for being exclusively used in forwarding w-UE data, and by RRC information, (RRC is proprietary Signaling or RRC, which are re-matched, completes message or sidelinkUEInformation) indicate that EPS carryings are exclusively used in forwarding w-UE to eNB Data (carry EPS load identifications/DRB marks/Logic Channel Identifier), in order to when there are two QCI values are identical by r-UE When EPS carryings (data for sending r-UE oneself, one is exclusively used in forwarding w-UE data), which eNB can distinguish EPS carryings/DRB is sent for forwarding w-UE data to correctly map the data into corresponding carrying.

Step 8:W-UE and eNB negotiates to carry by the EPS of relay forwarding, and specific method is shown in that example 5 is establishing w-UE EPS carry corresponding PC5 carrying and r-UE is exclusively used in after the Uu carryings of forwarding w-UE data, w-UE can negotiate with eNB The data of which EPS carrying are forwarded by r-UE, and later, the data of the EPS carryings of the w-UE of these agreements are just turned by r-UE Hair.

Example 2

This example provides the data of another wearable/eMTC/NB-IoT equipment (w-UE) by relaying r-UE forwardings Under scene, forwarding carrying configures and establishes related procedure specific example, as shown in Figure 9.This example and example 1 are substantially similar, only It is that the sequence of separate step is adjusted.

Step 0:W-UE has data to send or initiates EPS carrying foundation according to business demand.For traditional LTE flows, here It repeats no more.

Step 1:W-UE carries out relay discoveries and selection, and R13ProSe UE-to-Network relay have found flow.And After selecting relay UE, carries out safe floor 2 with selected relay UE and connect, specifically, as step 3 in example 1.

Step 2:W-UE and eNB negotiates to carry by the EPS of relay forwarding, and specific method is shown in that example 5 is different from example 1 In, after the EPS for establishing w-UE carries corresponding PC5 carryings, the data which EPS carrying w-UE and eNB negotiates pass through Relay forwarding, in this example, w-UE negotiates the EPS carryings by relay forwarding with eNB and then carries out corresponding PC5 carryings It establishes and r-UE is exclusively used in the foundation that the Uu of forwarding w-UE data is carried.

Step 3:After w-UE and eNB negotiate the data of which EPS carrying by relay forwarding, eNB is that w-UE configures these EPS carries corresponding PC5 carryings, and PC5 carrying configuration informations are issued w-UE by eNB by RRC reallocation messages.Specifically, PC5 is held Configuration information is carried as introduced in step 2 in example 1.And after the completion of PC5 is carried and is established (i.e. after the completion of step 4), w- UE sends RRC re-matching completion message instruction PC5 carryings to eNB and establishes completion.

Step 4-5:PC5 carries configuration interactive between w-UE and r-UE and carrying is established, and r-UE carries out receiving control to w-UE System.Specifically, as step 4-5 in example 1.

Step 6:After message is established in the PC5 carryings for receiving w-UE and PC5 carryings are established in receiving, r-UE judges whether r-UE It needs to establish the EPS carryings for being exclusively used in forwarding w-UE data, configuration is established in the PC5 carryings that r-UE is sent according to the w-UE received In information PC5 carrying QoS information and r-UE safeguarded EPS carrying list information, it is determined whether have meet the requirements it is special In forwarding w-UE data EPS carrying, if it is not, r-UE to network originated traffic ask, bearing resource distribution request or Bearing resource modification request, is established or modification is exclusively used in forwarding the EPS carryings of w-UE data, meanwhile, these of w-UE to MME are asked Forwarding carrying instruction can be carried by asking in message, related news (Bearer setup are established in the carrying for issuing eNB in MME later Request/Session management request/Bearer modify request) in also carry forwarding carrying refer to Show, it is tradition LTE flows which, which carries other steps in Establishing process, and which is not described herein again.

In the data for deciding through consultation which EPS carrying of w-UE by relay forwarding, and establishes corresponding PC5 carryings and held with forwarding Uu After load, the data of these EPS decided through consultation carryings of w-UE are just by relaying r-UE forwardings.

Example 3

This example provides the data of another wearable/eMTC/NB-IoT equipment (w-UE) by relaying r-UE forwardings Scene, when having downlink w-UE data to reach eNB, configuration is established in PC5 carryings and the specific reality of related procedure is established in Uu forwarding carryings Example, as shown in Figure 10.

Step 1:For w-UE according to demands such as QoS, economize on electricitys, high level determines communication mode of the selection by relay forwarding, w- UE (is established in request message in RRC connections when RRC connections are established and is carried the instruction of PC5 transmission interest) to eNB instruction PC5 communications Interest.

Step 2:W-UE carries out relay discoveries and selection, and R13ProSe UE-to-network relay have found flow.W- UE informs eNB after selecting relay, by selected relay information, that is, passes through sidelinkUEInformation message Carry the ProSe UE ID of relay.W-UE establishes safe floor 2 with relay UE and connect, specifically, with step 3 one in example 1 Sample.

Step 3-4:When network has the data for issuing w-UE, the EPS carryings that PGW initiates w-UE are established, and are established in carrying After the completion, w-UE data are transferred to eNB, traditional LTE flows by the carrying.

Step 5:W-UE has informed eNB its PC5 transmission interest instructions, and eNB preserves the selected relay of w-UE W-UE data need to be transmitted to w-UE by UE information, eNB by relay.If eNB has found that relay UE do not meet qos requirement The Uu DRB, w-UE and r-UE for being exclusively used in forwarding w-UE data not yet establish corresponding PC5 carrying, eNB is w-UE and r-UE It carries out PC5 carryings configuration and the Uu carryings of forwarding w-UE data configures.

Step 6:The foundation of w-UE PC5 carryings.ENB, which carries PC5 to establish to configure, is sent to w-UE.Optionally, PC5 is held Load is established in configuration information comprising configuration instruction simultaneously, informs that w-UE/r-UE, eNB have been that other side configures PC5 carryings, it is not necessary to send out Play PC5 carrying interactions.After the completion of PC5 is carried and established, w-UE sends RRC reallocation messages and has been established to eNB instruction PC5 carryings At.

Step 7:R-UE PC5 carryings are established and the Uu DRB of forwarding w-UE data are established.PC5 is carried and is established configuration by eNB And the Uu DRB configurations of forwarding w-UE data are sent to w-UE, Uu DRB configurations include:Uu DRB marks, pdcp configurations, rlc match It sets, Logic Channel Identifier, logic channel configuration.It initiates to establish the EPS carryings for forwarding w-UE data with r-UE in examples detailed above Difference is, forwards the EPS carryings of w-UE data to obtain Uu DRB by foundation in examples detailed above, and w- is forwarded in this example The Uu DRB of UE data, the one section of DRB only to eat dishes without rice or wine are carried without corresponding EPS.R-UE is carried to establish and is completed and turn in PC5 After the completion of sending out Uu DRB foundation, sends RRC reallocation messages and indicate that completion is established in PC5 carryings and Uu DRB foundation is completed to eNB.

The data of w-UE are sent to relay by eNB by the newly-established DRB for being exclusively used in forwarding w-UE data of relay UE After UE, relay UE receive the data of w-UE, w-UE is sent the data to by PC5 carryings.Relay UE forward w-UE data PC5 carrying and Uu carrying completion has been established, subsequently have the uplink/downlink data of the w-UE of identical QoS demand that can pass through Relay UE forwardings.

Figure 11 is similar with Figure 10, and difference is that initiating PC5 carryings to w-UE from relay UE establishes, and relay UE pass through hair Tradition EPS carrying Establishing process establishes the Uu carryings (identical with example 1) for being exclusively used in forwarding w-UE data.When there is w-UE Downlink data reaches eNB, and eNB transmission PC5 carryings establish configuration information and relay UE, relay UE is given to be held to w-UE initiations PC5 It carries and establishes, carry PC5 carryings and establishes configuration information, w-UE is received after PC5 carryings establish configuration information, is established PC5 by configuration and is held Carry, and send PC5 carrying establish response message give relay UE, relay UE complete PC5 carrying establish after send messages to ENB informs that PC5 carryings are established and completes.While having w-UE downlink datas to reach eNB, eNB checks whether relay UE have satisfaction The EPS carryings of the forwarding w-UE data of qos requirement, if it is not, eNB instruction relay UE initiate to establish forwarding w-UE data EPS carrying, and the EPS carry establish after the completion of, relay UE to eNB indicate the EPS carrying for forwarding w-UE data.

Example 4

This example provides the data of another wearable/eMTC/NB-IoT equipment (w-UE) by relaying r-UE forwardings Scene, w-UE and eNB do not have direct signaling interaction, w-UE control plane signalings and user face data to be forwarded, had by relay UE Body example is as shown in figure 12.Relay UE are in connected state and have activated relay relevant configurations.

Step 0:Relay is found and selection.Same examples detailed above.

Step 1:Find that w-UE establishes safe floor 2 with selected relay UE and connect/communication with after selection completing relay Connection.In this example, relay connections are established related news and are carried out by PC5 AS signalings.Relay UE are receiving the straight of w-UE After connecing communication request, sends sidelinkUEInformation and carry remote UE ID to eNB, inform that eNB there are w-UE connections To it, and to carry out relay communications.ENB preserves w-UE information.Optionally, relay UE are obtained from ProSe function The information such as the subscription information of remote UE and mandate, and these information are carried and are sent in sidelinkUEInformation To eNB.

Step 2-5:W-UE oneself generates RRC connections and establishes solicited message.Control plane signaling is forwarded to complete by relay Process is established in RRC connections.The RRC connection request information of generation is sent to relay UE, relay by w-UE by control plane message After UE is received, the RRC connection request information of w-UE is transmitted to eNB;ENB does access control to w-UE, is accessed allowing w-UE Afterwards, the RRC connections for sending w-UE establish information relay UE, relay UE are given to forward that information to w-UE;W-UE is completed After RRC connections are established, sends RRC connections completion information carrying Attach message and relay UE, relay UE is given to be transmitted to eNB, Attach message is forwarded to core net by eNB, and the attaching process for completing w-UE is forwarded by relay.

Step 6:The EPS carryings of w-UE are established.The EPS carrying configuration informations of w-UE are sent to relay UE by eNB, Relay UE are transmitted to w-UE.W-UE completes EPS carryings/Uu DRB with postponing, and sends RRC and re-matches and completes message to eNB, by Relay UE forwardings.

Step 7-8:The corresponding PC5 carryings of the EPS carryings of w-UE are established configuration information and are sent to relay UE by eNB, by Relay UE initiate PC5 carryings to w-UE and establish.And inform eNB after the completion of PC5 carryings are established.

The same with examples detailed above, relay UE can detect whether the Uu carryings for the forwarding w-UE data for meeting qos requirement, If no, will initiate to establish the EPS carryings for being exclusively used in forwarding w-UE data and be indicated to eNB.Later, identical QoS needs The uplink and downlink data of the w-UE asked just pass through relay forwarding.

Example 5

This example provides the w-UE and eNB mentioned in examples detailed above the methods for negotiating to carry by the EPS of relay forwarding.

Method one:W-UE chooses whether the communication party forwarded by relay according to QoS, economize on electricity demand etc. by high-rise Formula after selection, can inform the tendency of eNB its data communications in Attach, service request, RRC connections when establishing Property.This method is embodied in example 3.
