Adjacent communication service realizing method and device

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 ...

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 A, or log in to this application on terminal B, so it is difficult for the 3GPP network to maintain user Association between the application layer identifier and the UE's 3GPP network identifier

[0034] Based on the above reasons, when the application on the UE requires the use of proximity communication services, including the discovery of proximity relationships and the establishment of proximity communication connections, the network cannot determine the UE's 3GPP network identity based on the user's application layer identity, so the proximity communication service cannot be performed.
