ProSe information transmission method, terminal, and communications device
First Claim
1. A proximity service (ProSe) information transmission method implemented by a first ProSe entity, the method comprising:
- receiving from a first terminal a first message comprising a ProSe application identity (APP ID), wherein the first ProSe entity is in a home public land mobile network (HPLMN) of the first terminal;
sending to a second ProSe entity a second message comprising the ProSe APP ID, wherein the second ProSe entity is in a visited public land mobile network (VPLMN) of the first terminal;
receiving from the second ProSe entity a third message comprising a first identity, wherein the first identity is a codeword or a mask allocated to the ProSe APP ID by the second ProSe entity and comprises a first public land mobile network identity (PLMN ID) of the VPLMN;
generating a second identity according to the first identity, wherein the second identity comprises the first identity and a second PLMN ID of the HPLMN; and
sending to the first terminal a fourth message comprising the second identity, wherein, before the generating the second identity, the method further comprises;
acquiring first indication information indicating whether the first terminal is in a roaming state; and
determining, according to second indication information and when the first indication information indicates that the first terminal is in the roaming state, that the first terminal supports broadcasting of the second identity, wherein the second indication information indicates whether the first terminal can support broadcasting of the second identity.

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.

6. A proximity service (ProSe) information transmission method implemented by a second ProSe entity, the method comprising:
-
receiving from a first ProSe entity a second message comprising a ProSe application identity (APP ID), wherein the first ProSe entity is in a home public land mobile network (HPLMN) of a first terminal, and wherein the second ProSe entity is in a visited public land mobile network (VPLMN) of the first terminal; allocating a corresponding codeword or a mask to the ProSe APP ID, wherein the codeword or the mask comprises a first public land mobile network identity (PLMN ID) of the VPLMN; sending to the first ProSe entity a third message comprising a first identity, wherein the first identity is the codeword or the mask; receiving, from a second terminal after the second terminal acquires a second identity generated by the first ProSe entity according to the first identity, a fifth message comprising the second identity, wherein the second identity comprises the first identity and a second PLMN ID of the HPLMN; sending to the first ProSe entity and according to the second PLMN ID, a seventh message comprising the second identity; receiving, from the first ProSe entity after the first ProSe entity determines the ProSe APP ID according to the second identity, an eighth message comprising the ProSe APP ID; and sending to the second terminal a sixth message comprising the ProSe APP ID. - View Dependent Claims (7)

8. A first proximity service (ProSe) entity comprising:
-
a processor; a receiver coupled to the processor and configured to receive from a first terminal a first message comprising a ProSe application identity (APP ID), wherein the first ProSe entity is in a home public land mobile network (HPLMN) of the first terminal; and a transmitter coupled to the processor and configured to transmit to a second ProSe entity a second message comprising the ProSe APP ID, wherein the second ProSe entity is in a visited public land mobile network (VPLMN) of the first terminal, wherein the receiver is further configured to receive from the second ProSe entity a third message comprising a first identity, wherein the first identity is a codeword or a mask allocated to the ProSe APP ID by the second ProSe entity, and wherein the first identity comprises a first public land mobile network identity (PLMN ID) of the VPLMN, wherein the processor is configured to generate, according to the first identity, a second identity comprising the first identity and a second PLMN ID of the HPLMN of the first terminal, wherein the transmitter is further configured to transmit to the first terminal a fourth message comprising the second identity, and wherein the processor is further configured to; acquire, before the generating the second identity, first indication information indicating whether the first terminal is in a roaming state; and determine, according to second indication information and when the first indication information indicates that the first terminal is in the roaming state, that the first terminal supports broadcasting of the second identity, wherein the second indication information indicates whether the first terminal can support broadcasting of the second identity. - View Dependent Claims (9, 10, 11, 12)
