    Abstract: A ProSe information transmission method for a second terminal discovering a first terminal in a roaming state. The method includes: a first ProSe entity receives a first message sent by a first terminal, where the first message carries a ProSe application identity APP ID; sends a second message carrying the ProSe APP ID to a second ProSe entity; receives a third message carrying a first identity sent by the second ProSe entity, the first identity is a codeword or mask allocated to the ProSe APP ID by the second ProSe entity, and the first identity includes a PLMN ID of the VPLMN; generates a second identity according to the first identity, where the second identity includes the first identity and a PLMN ID of an HPLMN of the first terminal; and sends a fourth message to the first terminal, where the fourth message carries the second identity.

    Abstract: A data communication method, where a first device receives a request message from at least one second device, where the request message requests the first device to forward group data, and the request message carries a group identifier. The first device returns a response message to the at least one second device, where the response message carries a layer-2 address and an Internet Protocol (IP) address corresponding to the group identifier, and the first device sends the group data using the layer-2 address when receiving the group data sent by a third device to the IP address.

    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.
