Abstract: An inter-user equipment discovery method, apparatus and system are disclosed. In an embodiment, the method includes sending, by first user equipment, a discovery request message to a first proximity-based service entity, wherein the discovery request message comprises initial location information of the first user equipment and receiving a discovery response message sent by the first proximity-based service entity, wherein the discovery response message comprises a first code word of the first user equipment. The method further include generating a discovery message according to location offset information and the first code word, wherein the location offset information is an offset between a current location and an initial location of the first user equipment and broadcasting the discovery message, wherein the discovery message is used by a second user equipment to determine a location of the first user equipment.
