Embodiment 1

[0105] figure 2 A flow chart showing a discovery method provided by an embodiment of the present invention is applied to a first MCPTT UE under a Mission Critical Push To Talk (MCPTT) system (such as a public security system, a fire protection system) , used to enable the user of the first MCPTT UE to discover some other users or some communication groups around the user, wherein the first MCPTT UE may be any user equipment under the MCPTT system, which is not limited here, such as figure 2 As shown, the method may include:

[0106] 101. The first MCPTT UE sends a discovery message, wherein the discovery message includes: application layer identification information of a discovery target, and the discovery target is at least one target user or at least one target user of the first user using the first MCPTT UE communication group.

[0107] Among them, the discovery target can be some target users or some communication groups discovered by the first user using the first MCP...

Embodiment 2

[0134] Figure 5 A flow chart showing another discovery method provided by an embodiment of the present invention is applied to an MCPTT UE under a Mission Critical Push To Talk (MCPTT for short) system (such as a public security system and a fire protection system), It is used to enable some users or some communication groups to discover the users using the MCPTT UE, where the MCPTT UE can be any user equipment under the MCPTT system, which is not limited here, such as figure 2 As shown, the method may include:

[0135] 201. The MCPTT UE acquires an application layer identifier of a first user using the MCPTT UE.

[0136] Wherein, the application layer identifier of the user is used to identify the user, which may be an external identifier defined by the third generation partnership project (English: 3rd generation partnership project, abbreviation: 3GPP), such as: mobile subscriber number (English: Mobile Subscriber International ISDN / PSTN number, abbreviation: MSISDN), I...

Embodiment 3

[0156] Figure 6 It shows a structural diagram of an MCPTT UE30 provided by an embodiment of the present invention, which is used to execute the method described in Embodiment 1, such as Figure 6 As shown, the MCPTT UE30 may include:

[0157] A sending unit 301, configured to send a discovery message, where the discovery message includes: application layer identification information of a discovery target, where the discovery target is at least one target user or at least one communication group of the first user using the MCPTT UE Group.

[0158] Among them, the discovery target can be some target users or some communication groups discovered by the first user using the MCPTT UE. The target user can be any user who uses the MCPTT UE to obtain the MCPTT service, and can be in the same location as the first user using the MCPTT UE. The same communication group may also be in a different communication group from the first user using the MCPTT UE, which is not limited here; the...

Abstract

The invention discloses a discovery method and device, relates to the technical field of wireless communication, and aims to solve the problems that two communication parties cannot accurately discover each other and cannot ensure that the two communication parties perform service communication in a Prose mode in the prior art. The method provided by the present invention comprises: sending a discovery message, the discovery message comprising application layer identification information of a discovery target, the discovery target being at least one target user or at least one communication group of a first user using a first MCPTT UE; and receiving a response message sent by second MCPTT UE, wherein the response message comprises a layer 2 identifier of the second MCPTT UE and an application layer identifier of a user using the second MCPTT UE.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a discovery method and equipment. Background technique [0002] The Mission Critical Push To Talk (MCPTT) system can support Direct Mode Operation (DMO) scenarios, as defined in TS22.179, MCPTT can support one-to-one ) communication or private call (private call) two DMO scenarios. In the MCPTT system, the same user can not only belong to multiple communication groups (group), but also use different MCPTT user equipment (User Equipment, referred to as UE) to obtain MCPTT services, for example: in figure 1 In the shown MCPTT system, user1 belongs to communication group 1 and communication group 2, and user1 can use MCPTT UE1, MCPTT UE2 and MCPTT UE3 to obtain MCPTT services. [0003] Since a user in the MCPTT system can use different MCPTT UEs to obtain MCPTT services, in order to ensure normal communication, the communicating parties in the DMO scenario ...
