Abstract

The present disclosure provides a ProSe information transmission method, a terminal, and a communications device. The method includes: acquiring, by a second terminal, a fourth code word broadcast by a first terminal, where the fourth code word is a code word that is allocated to the first terminal by a first ProSe entity; sending, by the second terminal, a first message to a second ProSe entity when the fourth code word matches a prestored code word, where the first message carries the fourth code word and a first application identity; receiving, by the second terminal, a second message sent by the second ProSe entity, where the second message carries a second identity; and discovering, by the second terminal, a first application user according to the second identity. The present disclosure is applicable to the communications field.

First claim

What is claimed is:

1. A proximity service (ProSe) information transmission method, wherein the method comprises:
receiving, by a receiving ProSe entity, a first message sent by a monitoring terminal, the first message instructing the receiving ProSe entity to acquire a first application user identity that is allocated to a first application user by a first application server, the first application user being a user of a first application of a first terminal, the first message comprising a code word allocated by a first ProSe entity, the first application server being an application server of the first application, and the receiving ProSe entity being a ProSe entity in a first home public land mobile network (HPLMN) of the monitoring terminal;
acquiring, by the receiving ProSe entity, the first application user identity by, sending to the first ProSe entity the code word received in the first message, and in response, receiving from the first ProSe entity the first application user identity,
wherein the first ProSe entity is in a second HPLMN of the first terminal, the code word being related to a plurality of application user identities including the first application user identity, and the second HPLMN being a different HPLMN than the first HPLMN; and
sending, by the receiving ProSe entity, a second message to the monitoring terminal, the second message comprising the first application user identity received from the first ProSe entity, the first application user identity indicating the first application user discovered by the monitoring terminal.

2. The method according to claim 1 , wherein the first application user identity comprises a temporary application user identity (Temp APP User ID) or a real application user identity allocated by the application server.

3. The method according to claim 1 , further comprising:
before receiving the first message sent by the monitoring terminal, receiving, by the receiving ProSe entity, a fifth message sent by the monitoring terminal, the fifth message instructing the receiving ProSe entity to acquire the code word allocated to the first terminal by the first ProSe entity;
acquiring, by the receiving ProSe entity, the code word; and
sending, by the receiving ProSe entity, a sixth message to the monitoring terminal, wherein the sixth message comprises the code word.

4. The method according to claim 3 , wherein the fifth message comprises a third identity and the application identity, the third identity comprising a temporary terminal identity allocated to the monitoring terminal by the receiving ProSe entity, and the application identity identifying the first application; and
acquiring the code word comprises:
sending, by the receiving ProSe entity, a seventh message to the first application server according to the application identity, wherein the seventh message comprises the third identity;
receiving, by the receiving ProSe entity, an eighth message sent by the first application server, the eighth message comprising a first identity, the first identity comprising a temporary terminal identity allocated to the first terminal by the first ProSe entity;
sending, by the receiving ProSe entity, a ninth message to the first ProSe entity, the ninth message comprising the first identity; and
receiving, by the receiving ProSe entity, a tenth message sent by the first ProSe entity, the tenth message comprising the code word.

5. The method according to claim 3 , wherein the fifth message comprises first information, a fourth identity, and the application identity, the first information comprising a third identity or a sixth identity, the third identity comprising a temporary terminal identity allocated to the monitoring terminal by the receiving ProSe entity, the sixth identity comprising a terminal identity of the monitoring terminal, the fourth identity comprising a temporary application user identity allocated to a second application user by the first application server, the second application user being a user of the first application of the monitoring terminal, and the application identity being the application identity of the first application; and
acquiring the code word comprises:
sending, by the receiving ProSe entity, a seventh message to the first application server according to the application identity, the seventh message comprising the fourth identity;
receiving, by the receiving ProSe entity, an eighth message sent by the first application server, the eighth message comprising a first identity, the first identity comprising a temporary terminal identity allocated to the first terminal by the first ProSe entity;
sending, by the receiving ProSe entity, a ninth message to the first ProSe entity, the ninth message comprising the first identity; and
receiving, by the receiving ProSe entity, a tenth message sent by the first ProSe entity, the tenth message comprising the code word.

6. The method according to claim 1 , further comprising:
before sending the second message to the monitoring terminal, sending, by the receiving ProSe entity, a third message to the first application server, the third message comprising the first application user identity, the first application user identity configured to cause the first application server to determine whether a broadcast request of the first application user is allowed; and
receiving, by the receiving ProSe entity, a fourth message sent by the first application server, the fourth message indicating whether the broadcast request of the first application user is allowed.

7. The method according to claim 6 , further comprising:
after sending the second message to the monitoring terminal, sending, by the receiving ProSe entity, a fifth message to the first ProSe entity, the fifth message comprising a first identity, the application identity, and a fourth identity, the first identity comprising a temporary terminal identity allocated to the first terminal by the first ProSe entity, the application identity identifying the first application, the fourth identity comprising a temporary application user identity allocated to a second application user by the first application server, the second application user being a user of the first application of the monitoring terminal.

8. The method according to claim 1 , further comprising:
before receiving the first message, receiving, by the receiving ProSe entity, a sixth message sent by the monitoring terminal, the sixth message comprising a third identity and the application identity, the third identity comprising a temporary terminal identity allocated to the monitoring terminal by the receiving ProSe entity, and the application identity identifying the first application;
determining, by the receiving ProSe entity, a fourth identity according to the third identity and the application identity, the fourth identity comprising a temporary application user identity allocated to a second application user by the first application server, the second application user being the user of the first application of the monitoring terminal;
sending, by the receiving ProSe entity, a seventh message to the first application server, the seventh message comprising the fourth identity;
receiving, by the receiving ProSe entity, an eighth message sent by the first application server, the eighth message comprising a correspondence between the first identity and the first application user identity, the correspondence between the first identity and the first application user identity being determined by the first application server according to the fourth identity, the first identity comprising the temporary terminal identity allocated to the first terminal by the first ProSe entity;
sending, by the receiving ProSe entity, a ninth me
