Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is a part of embodiment of the invention, rather than the embodiment of whole.Based on this
Embodiment in bright, the every other enforcement that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
Fig. 3 is refer to, Fig. 3 is a kind of stream of radio resource control information transmission method that first embodiment of the invention is provided
Journey schematic diagram.As shown in figure 3, the method in the embodiment of the present invention includes：
S301, first terminal receives the Radio Resource transmitted by the first Signaling Radio Bearer SRB that second terminal sends
Control RRC information, the first Signaling Radio Bearer SRB is communication interface between the first terminal and the second terminal
Radio bearer.Wherein, first terminal can be relaying UE, and second terminal can be distal end UE.
In implementing, because second terminal is not in base station range, second terminal needs to set up RRC companies with eNB
Connect, search first can provide the first terminal of relay services, if searched, by the encapsulation of radio resource control RRC message
To in Signaling Radio Bearer SRB, then radio resource control RRC message is transmitted to first terminal by Signaling Radio Bearer SRB.
Optionally, the first terminal receive second terminal send by the first Signaling Radio Bearer SRB transmit
Before radio resource control RRC message, first terminal sets up the second Data Radio Bearer SRB with the base station.For example,
SRB0, SRB1 and SRB2 can be set up between U2NR and eNB, if U2NR and eNB only establishes SRB0, according to difference
The security requirement of SRB and resource use characteristic, RRC information to be only capable of being transferred to eNB by SRB0.
S302, the first terminal is searched and first Signaling Radio Bearer from the resource mapping table being pre-configured with
The corresponding second Data Radio Bearer SRB of SRB, the second Data Radio Bearer SRB are between the first terminal and base station
Communication interface radio bearer.
In implementing, the resource mapping table includes wireless corresponding to multiple first Signaling Radio Bearer SRB
Link controls the mapping relations one by one of RLC entities and multiple second Signaling Radio Bearer SRB.For example, U2NR and eNB it
Between can set up after SRB0, SRB1 and SRB2, the RRC of distal end UE is also required to 3 SRB (SRB0, SRB1 and SRB2), so as to
The impact of the RRC agreements to distal end UE is reduced, and is set up and the second Signaling Radio Bearer SRB (SRB0, SRB1 and SRB2)
Mapping relations one by one.Wherein, the corresponding RLC entities of SRB0 of PC5 (interface between distal end UE and relaying UE) mouth and Uu (in
After the interface between UE and base station) SRB0 of mouth is corresponding；The corresponding RLC entities of SRB1 of PC5 mouths are corresponding with the SRB1 of Uu mouths；

CCCH (CCCH, Common Control Channel) is transmitted, and SRB1 and SRB2 is in DCCH (Dedicated
Control Channel, DCCH) transmission, and SRB0, SRB1 and SRB2 have respective priority, it is therefore desirable to
Ensure the wireless spread-spectrum technology RLC entities and multiple second Signaling Radio Bearers corresponding to the first Signaling Radio Bearer SRB
The mapping relations one by one of SRB.
S303, the first terminal to the second Data Radio Bearer SRB that the base station is sent by finding is passed
The defeated radio resource control RRC message.
In implementing, specific ratio can be added in the RLC packets headers that the radio resource control RRC message is used
Spy, the specific bit is used for the base station and distinguishes the radio resource control RRC message from the first terminal or described
Second terminal.For example, Uu mouths SRB0, SRB1 and SRB2 transmitted over resources distal end UE SRB0, SRB1 and SRB2 signalings,
ENB needs to make a distinction the control signaling from distal end UE and the data from U2NR, therefore relaying UE can be in RRC information
The RLC packets headers for being used add R bits, are that relaying UE sends out when eNB receives RRC information, to distinguish the message
Return is that distal end UE sends.
In embodiments of the present invention, first terminal receive first second terminal transmission by the first Signaling Radio Bearer
The radio resource control RRC message of SRB transmission；Then search from the resource mapping table being pre-configured with and wirelessly held with the first signaling
Carry the corresponding second Data Radio Bearer SRB of SRB；The second Data Radio Bearer SRB by finding is sent after most to base station
The radio resource control RRC message of transmission, realizes supporting to set up RRC connections between R-UE and eNB, while not affecting U2NR certainly
Body and the RRC control signaling resource of network side, improve motility and the Business Processing efficiency of Business Processing mode.
