Abstract

Disclosed are a method and apparatus for allocating a resource on a PC5 interface, comprising: acquiring a PC5 aggregation maximum bit rate of a user equipment; and after receiving a request for allocating a resource on a PC5 interface for the user equipment, allocating the resource on the PC5 interface according to the PC5 aggregation maximum bit rate of the user equipment. According to the present application, when a plurality of user equipment use a PC5 interface to perform communication, the solution of controlling, on the PC5, the total resources used by a UE on the PC5 interface can be provided, thus better controlling the service quality on the PC5 interface, and making up for the shortcomings of the prior art.

First claim

The invention claimed is:

1. A method for allocating a resource on a PC5 interface, the method comprising:
obtaining a PC5 Aggregated Maximum Bit Rate (AgMBR) of a User Equipment (UE); and
allocating a resource on the PC5 interface according to the PC5 AgMBR of the UE upon reception of a request for allocating a resource on the PC5 interface to the UE;
wherein:
obtaining the PC5 AgMBR of the UE in a Long Term Evolution (LTE) procedure by an eNB; and
allocating the resource on the PC5 interface according to the PC5 AgMBR of the UE after the request for allocating a resource on the PC5 interface to the UE is received, wherein the resource on the PC5 interface allocated to the UE is used for the UE to set up a bearer through a relay UE;
wherein the method further comprises:
determining bearer rates having been set up, according to Quality of Service (QoS) parameters of PC5 bearers having been set up by the UE, and determining a bearer rate to be set up, according to the request for allocating a resource on the PC5 interface to the UE; and
when the resource is allocated according to the PC5 AgMBR of the UE, allocating the resource according to the bearer rates having been set up, the bearer rate to be set up, and the PC5 AgMBR of the UE.

2. The method according to claim 1 , wherein:
obtaining the PC5 AgMBR of the UE when context information of the UE is obtained by an evolved Node B (eNB) through a Mobility Management Entity (MME); and
allocating the resource on the PC5 interface according to the PC5 AgMBR of the UE after the request for allocating a resource on the PC5 interface to the UE is received by the eNB.

3. The method according to claim 1 , wherein the request for allocating a resource on the PC5 interface to the UE is transmitted by the UE or the relay UE.

4. The method according to claim 1 , wherein the method further comprises:
if a sum of the bearer rates having been set up, and the bearer rate to be set up is greater than the AgMBR, then returning a rejection reason after the request for allocating a resource on the PC5 interface to the UE is rejected, or releasing a PC5 bearer having been set up with a low priority, after the request for allocating a resource on the PC5 interface to the UE is accepted.

5. The method according to claim 1 , wherein the method further comprises:
passing the PC5 AgMBR to the relay UE if there is no PC5 bearer having been set up between the UE and the relay UE.

6. The method according to claim 1 , wherein:
obtaining the PC5 AgMBR of the UE from information passed by an eNB to a relay UE; and
allocating by the relay UE the resource on the PC5 interface according to the PC5 AgMBR of the UE.

7. The method according to claim 6 , wherein the resource on the PC5 interface is allocated by the relaying UE according to the PC5 AgMBR of the UE among a resource on the PC5 interface allocated by the eNB to the relay UE.

8. The method according to claim 1 , wherein the method further comprises:
allocating a resource on the PC5 interface to a relay UE, and instructing the relay UE to allocate a resource on the PC5 interface to the UE among the resource on the PC5 interface allocated to the relay UE according to the PC5 AgMBR.

9. A network-side device, comprising: a processor, a memory, and a transceiver, wherein:
the processor is configured to read and execute programs in the memory to:
allocate a resource on a PC5 interface according to a PC5 Aggregated Maximum Bit Rate (AgMBR) of a User Equipment (UE) after the transceiver receives a request for allocating a resource on the PC5 interface to the UE; and
the transceiver is configured to transmit and receive data under the control of the processor to:
obtain the PC5 AgMBR of the UE;
obtain the PC5 AgMBR of the UE in a Long Term Evolution (LTE) at an eNB side; and
allocate the resource on the PC5 interface according to the PC5 AgMBR of the UE after a request for allocating a resource on the PC5 interface to the UE is received, wherein the resource on the PC5 interface allocated to the UE is used for the UE to set up a bearer through a relay UE;
wherein the processor is configured to:
determine bearer rates having been set up, according to Quality of Service (QoS) parameters of PC5 bearers having been set up by the UE, and determine a bearer rate to be set up, according to the request for allocating a resource on the PC5 interface to the UE; and
when the resource is allocated according to the PC5 AgMBR of the UE, allocate the resource according to the bearer rates having been set up, the bearer rate to be set up, and the PC5 AgMBR of the UE.

10. The device according to claim 9 , wherein the processor is configured to obtain the PC5 AgMBR of the UE when context information of the UE is obtained by an evolved Node B (eNB) through a Mobility Management Entity (MME); and
allocate the resource on the PC5 interface according to the PC5 AgMBR of the UE after the request for allocating a resource on the PC5 interface to the UE is received by the eNB.

11. The device according to claim 9 , wherein the transceiver is configured to receive the request for allocating a resource on the PC5 interface to the UE, transmitted by the UE or the relay UE.

12. The device according to claim 9 , wherein the processor is further configured to:
if a sum of the bearer rates having been set up, and the bearer rate to be set up is greater than the AgMBR, instruct the transceiver to return a rejection reason after the request for allocating a resource on the PC5 interface to the UE is rejected, or release a PC5 bearer having been set up with a low priority, after the request for allocating a resource on the PC5 interface to the UE is accepted.

13. The device according to claim 9 , wherein the processor is further configured to:
instruct the transceiver to pass the PC5 AgMBR to the relay UE if there is no PC5 bearer having been set up between the UE and the relay UE.

14. The device according to claim 9 , wherein the processor is configured to:
obtain the PC5 AgMBR of the UE from information passed by an eNB to a relay UE; and
allocate at the relay UE side the resource on the PC5 interface according to the PC5 AgMBR of the UE.

15. The device according to claim 14 , wherein the processor is configured to allocate at the relay UE side a resource on the PC5 interface according to the PC5 AgMBR of the UE among a resource on the PC5 interface allocated by the eNB to the relay UE.
