Abstract

A method, a device, and a system for sending and receiving a message for a ProSe. The method includes determining, by a base station, a device identifier list of a ProSe user equipment and a resource parameter that is used by the ProSe user equipment to send a discovery signal; and broadcasting, by the base station, a first indication message, where the first indication message indicates the device identifier list and the resource parameter, so that a first ProSe user equipment performs a ProSe with a second ProSe user equipment. According to the method and the device for sending and receiving a message for a ProSe that are provided by the embodiments, a rate that a ProSe user equipment is sensed can be improved.

Claims

broadcasting, by the base station, a first indication message, wherein the first indication message indicates the device identifier list and the resource parameter, so that the first ProSe user equipment receives the first indication message broadcasted by the base station and performs, according to the device identifier list and the resource parameter that are indicated by the first indication message, a ProSe with the second ProSe user equipment.

2. The method according to claim 1, wherein the first indication message carries the device identifier list and the resource parameter.

3. The method according to claim 1, wherein the first indication message indicating the device identifier list and the resource parameter comprises the first indication message carrying the device identifier list, wherein the device identifier in the device identifier list is mapped to the resource parameter using a first preset function relationship.

4. The method according to claim 1, wherein the first indication message indicating the device identifier list and the resource parameter comprises the first indication message carrying the resource parameter, wherein the resource parameter is mapped to the device identifier in the device identifier list using a second preset function relationship.

5. The method according to claim 1, wherein the first indication message indicating the device identifier list and the resource parameter comprises the first indication message carrying the device identifier list and a resource set, wherein the resource set is a set of resource parameters, and wherein the device identifier in the device identifier list corresponding with the resource parameter comprises a position of the device identifier in the device identifier list corresponding to a position of the resource parameter in the resource set.

6. The method according to claim 1 further comprising broadcasting, by the base station, a second indication message, wherein the second indication message carries a resource set, and wherein the resource set is a set of the resource parameter, wherein the first indication message indicating the device identifier list and the resource parameter comprises the first indication message carrying the device identifier list, and wherein the device identifier in the device identifier list corresponding with the resource parameter comprises a position of the device identifier in the device identifier list corresponding to a position of the resource parameter in the resource set.

7. The method according to claim 1, wherein the resource parameter is determined by any one or a combination of the following:

a time-domain resource parameter, a frequency-domain resource parameter, and a code-word resource parameter.

8. The method according to claim 1 further comprising determining, by the base station, a service identifier of the ProSe user equipment, wherein the service identifier of the ProSe user equipment corresponds with the device identifier of the ProSe user equipment, and wherein the first indication message further indicates the service identifier of the ProSe user equipment.

9. A method for sending a message for a proximity service (ProSe) comprising:

determining, by a base station, a device identifier list of a ProSe user equipment and a service identifier of the ProSe user equipment, wherein a device identifier in the device identifier list corresponds with the service identifier, and wherein the ProSe user equipment comprises a first ProSe user equipment and a second ProSe user equipment, or the ProSe user equipment comprises a second ProSe user equipment; and

broadcasting, by the base station, a third indication message, wherein the third indication message indicates the device identifier list and the service identifier, so that the first ProSe user equipment receives the third indication message broadcasted by the base station and performs, according to the device identifier list and the service identifier that are indicated by the third indication message, a ProSe with the second ProSe user equipment.

10. A base station, comprising:

a sender; and

a processor, wherein the processor is configured to determine a device identifier list of a proximity service (ProSe) user equipment and a resource parameter that is used by the ProSe user equipment to send a discovery signal, wherein a device identifier in the device identifier list and the resource parameter have a correspondence, and wherein the ProSe user equipment comprises a first ProSe user equipment and a second ProSe user equipment, or the ProSe user equipment comprises a second ProSe user equipment, wherein the processor is further configured to generate a first indication message, wherein the first indication message indicates the device identifier list and the resource parameter, and wherein the sender is configured to broadcast the first indication message, so that the first ProSe user equipment receives the first indication message broadcasted by the base station and performs, according to the device identifier list and the resource parameter that are indicated by the first indication message, a ProSe with the second ProSe user equipment.

11. The base station according to claim 10, wherein the first indication message carries the device identifier list and the resource parameter.

12. The base station according to claim 10, wherein the first indication message indicating the device identifier list and the resource parameter comprises the first indication message carrying the device identifier list, wherein the device identifier in the device identifier list is mapped to the resource parameter using a first preset function relationship.
