Problems solved by technology

This requirement is related to factors such as the terminal's proximity relationship signing information, network configuration, and user relationship at the application layer. Due to the variety of applications on the terminal, the identification of the application layer is also complicated. It is impossible for the 3GPP network to integrate all the application layers on the UE The identity is associated with the UE's 3GPP network identity; in addition, since the application layer and the network layer should be independent of each other, the user can log in to an application on terminal

Embodiment 1

[0134] The application on the terminal triggers the process of ProSe discovery (proximity communication service discovery) to search for nearby users, such as Figure 5 shown, including:

[0135] Step S501, the user uses an application to search for nearby users, and the user terminal sends an application layer request to the application server, instructing to search for all friends or a certain friend on the application;

[0136] Step S502, the application server searches for nearby friends according to the current terminal location or login IP address and other information, the search range can be indicated by ProSe Server, user instruction or server pre-configuration, so as to determine the User ID of nearby friends;

[0137] Step S503, the application server finds the corresponding ProSe ID A according to the User ID of the search user, and finds the corresponding ProSe ID list according to the User ID in the searched friend list;

[0138] Step S504, the application serve...

Embodiment 2

[0146] Use the ProSe ID to perform ProSe discovery on the terminal, such as Figure 6 shown, including:

[0147] Step S601, the user provides the ProSe ID of the target user to search for the user, the user terminal sends a Discovery request to the network, and the request carries the ProSe ID of the initiating terminal and the target terminal and the Application ID of the application program that triggers the search on the terminal; the ProSe ID of the target user The ID can be obtained by querying the DNS server using the user ID of the application layer of the target user.

[0148] Step S602, after the MME in the network receives the Discovery request, it obtains the subscription information of the UE according to the ProSe ID of the initiating terminal in the request, and judges whether the terminal is allowed to use the proximity communication service according to the subscription information, and if so, forwards the Discovery request to ProSe Server;

[0149] In actual...

Embodiment 3

[0154] The application on the terminal triggers the establishment of the ProSe connection, such as Figure 7 shown, including:

[0155] Step S701, an application on the terminal triggers the establishment of a proximity communication connection to a neighboring user, and the user terminal sends an application layer request to the application server;

[0156] Step S702, the application server queries the current location or IP address information of the terminal according to the User ID of the terminal in the request, and determines whether proximity communication between the two is possible;

[0157] Step S703, the application server finds the corresponding ProSe ID A according to the User ID of the initiating terminal, and finds the corresponding ProSe ID according to the User ID of the target terminal;

[0158] Step S704, the application server searches for a suitable ProSe Server A according to the ProSe ID A, such as using DNS Server;

[0159] Step S705, the application ...

Abstract

The invention discloses an adjacent communication service realizing method and device, and relates to the communication technology. In the UE contact signing process, an adjacent communication service identifier is assigned for the UE, so that after an adjacent communication service request sent by the UE is received, the adjacent communication service identifier of the UE is determined, and then adjacent communication service is realized according to the adjacent communication service identifier of the UE, so that the condition that the adjacent communication service cannot be performed because a network cannot determine the 3GPP network internal identifier of the UE according to the application identifier of a user can be avoided, so the adjacent communication service of the UE can be realized.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method and device for realizing a proximity communication service. Background technique [0002] At present, 3GPP (3rd Generation Partnership Project, the third generation mobile communication standardization organization) is studying the problem of proximity communication between devices. Layer data transmission can be carried out directly between two devices without passing through the mobile communication network, or forwarded through the serving base station connected to the devices without passing through the core network. In order to achieve this goal, it is also necessary to study how the application layer triggers the network layer to discover the proximity relationship and establish proximity communication, and how the application layer user service identifier is associated with the network layer identifier. [0003] In the current communication process between two ...
