    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.

    Abstract: Embodiments provide a core network selection method, an apparatus, and a system. The method includes the following steps: obtaining first dedicated core network (DCN) information from an access network device, where the first DCN information includes information about at least one DCN that can be accessed by the access network device. The method also includes selecting a to-be-accessed DCN from the at least one DCN according to the first DCN information, and sending information about the to-be-accessed DCN to the access network device, so that the access network device determines a core network device according to the information about the to-be-accessed DCN.
