Method, device, and system for sending and receiving message for proximity service
First Claim
1. A method for sending a message for a proximity service (ProSe) comprising:
- collecting, by a base station, a first device identifier and a first resource parameter of a first ProSe user equipment in a first discovery signal for being discovered in a Device to Device (D2D) communication link, wherein the first discovery signal is sent by the first ProSe user equipment using the first resource parameter;
collecting, by the base station, a second device identifier and a second resource parameter of a second ProSe user equipment in a second discovery signal for being discovered in the D2D communication link, wherein the second discovery signal sent is by the second ProSe user equipment using the second resource parameter; and
broadcasting, by the base station, an indication message that indicates a device identifier list and a resource parameter list before the first ProSe user equipment and the second ProSe user equipment sense existence of each other, wherein the device identifier list comprises the first device identifier and the second device identifier, wherein the resource parameter list comprises the first resource parameter and the second resource parameter, and wherein the device identifier list is mapped to the resource parameter list.

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.

4. A base station, comprising:
-
a processor configured to collect a first device identifier and a first resource parameter of a first ProSe user equipment in a first discovery signal for being discovered in a Device to Device (D2D) communication link, wherein the first discovery signal is sent by the first ProSe user equipment using the first resource parameter; collect a second device identifier and a second resource parameter of a second ProSe user equipment in a second discovery signal for being discovered in the D2D communication link, wherein the second discovery signal is sent by the second ProSe user equipment using the second resource parameter; and generate an indication message indicating a device identifier list and a resource parameter list before the first ProSe user equipment and the second ProSe user equipment sense existence of each other, wherein the device identifier list comprises the first device identifier and the second device identifier, wherein the resource parameter list comprises the first resource parameter and the second resource parameter, and wherein the device identifier list is mapped to the resource parameter list; and a transmitter coupled to the processor and configured to broadcast the indication message. - View Dependent Claims (5, 6)
