Abstract

Embodiments of the present invention provide a content publishing method and a user equipment. The content publishing method includes: obtaining, by a first user equipment supporting a D2D function, a resource for broadcasting information of the first user equipment. The method also includes broadcasting, by the first user equipment, the information of the first user equipment on the obtained resource, so that a second user equipment obtains and sends the information of the first user equipment to a network-side device to set up a connection with the first user equipment, where the second user equipment supports the D2D function and is matched with the first user equipment.

Claims

1. A method, comprising:

obtaining, by a first user equipment supporting a device to device (D2D) function, a plurality of resources, wherein the plurality of resources are allocated in advance by a serving base station of a cell where the first user equipment is located, the plurality of resources are allocated to user equipments supporting the D2D function in the cell, and the plurality of resources are allocated for broadcasting information about the user equipments supporting the D2D function in the cell;

selecting, by the first user equipment, a first resource of the plurality of resources for broadcasting information about the first user equipment; and

broadcasting, by the first user equipment to a second user equipment supporting the D2D function, the information about the first user equipment on the first resource.

2. The method according to claim 1, wherein the plurality of resources are broadcast by the serving base station through a broadcast message.

3. The method according to claim 1, wherein an interference level of the first resource for broadcasting information about the first user equipment is lower than a predetermined threshold.

4. The method according to claim 1, wherein the information about the first user equipment comprises one or a combination of an identifier, service information, a service code, or application layer service information of the first user equipment.

5. The method according to claim 4, wherein before broadcasting the information about the first user equipment on the first resource, the method further comprises:

sending, by the first user equipment, the application layer service information of the first user equipment to a service management server, and receiving the service information corresponding to the first user equipment and the service code allocated by the service management server to the first user equipment, wherein the service information is found by the service management server according to the application layer service information of the first user equipment.

6. The method according to claim 1, wherein broadcasting the information about the first user equipment on the first resource comprises:

broadcasting, by the first user equipment in a discontinuous transmission mode, the information about the first user equipment on the first resource periodically.

7. A method, comprising:

allocating, by a base station to a first user equipment supporting a device to device (D2D) function, a first resource for broadcasting information about the first user equipment to another user equipment supporting the D2D function; and

sending, by the base station, an identification of the first resource to the first user equipment, wherein the base station allocates, in advance, a plurality of resources to user equipments supporting the D2D function in a cell where the first user equipment is located, wherein the plurality of resources are used for broadcasting information about the user equipments supporting the D2D function in the cell where the first user equipment is located, and the first resource for broadcasting information about the first user equipment is selected by the first user equipment from the plurality of resources.

8. The method according to claim 7, wherein the plurality of resources are broadcast by the base station through a broadcast message.

9. The method according to claim 7, wherein an interference level of the first resource for broadcasting information about the first user equipment is lower than a predetermined threshold.

10. A device, applied to first user equipment supporting a device to device (D2D) function, the device comprising:

a processor; and

a non-transitory computer readable storage medium storing a program to be executed by the processor, the program including instructions for;

obtaining a plurality of resources that are allocated in advance by a serving base station of a cell where the first user equipment is located, wherein the plurality of resources are allocated to user equipments supporting the D2D function in the cell, and the plurality of resources are allocated for broadcasting information about the user equipments supporting the D2D function in the cell; and

selecting a first resource of the plurality of resources for broadcasting information about the first user equipment; and

broadcasting, to a second user equipment supporting the D2D function, the information about the first user equipment on the first resource.

11. The device according to claim 10, wherein the plurality of resources are broadcast by the serving base station through a broadcast message.

12. The device according to claim 10, wherein an interference level of the first resource for broadcasting information about the first user equipment is lower than a predetermined threshold.

13. The device according to claim 10, wherein the information about the first user equipment comprises one or a combination of an identifier, service information, a service code, or application layer service information of the first user equipment.

14. The device according to claim 13, wherein the program further includes instructions for:

sending, before broadcasting the information about the first user equipment on the first resource, the application layer service information of the first user equipment to a service management server; and

receiving the service information corresponding to the first user equipment and the service code allocated by the service management server to the first user equipment, wherein the service information is found by the service management server according to the application layer service information of the first user equipment.

15. The device according to claim 10, wherein broadcasting the information about the first user equipment on the first resource comprises:

broadcasting, in a discontinuous transmission mode, the information about the first user equipment on the first resource periodically.

16. A device applied to a base station, the device comprising:

a processor; and

a non-transitory computer readable storage medium storing a program to be executed by the processor, the program including instructions for;

allocating, to a first user equipment supporting a device to device (D2D) function, a first resource that is used for broadcasting information about the first user equipment to another user equipment supporting the D2D function; and

sending an identification of the first resource to the first user equipment, wherein the base station is configured to allocate, in advance, a plurality of resources to user equipments supporting the D2D function in a cell where the first user equipment is located, wherein the plurality of resources are allocated for broadcasting information about the user equipments supporting the D2D function in the cell where the first user equipment is located, and the first resource for broadcasting information about the first user equipment is selected by the first user equipment from the plurality of resources.

17. The device according to claim 16, wherein the plurality of resources are broadcast by the base station through a broadcast message.

18. The device according to claim 16, wherein an interference level of the first resource for broadcasting information about the first user equipment is lower than a predetermined threshold.
