Embodiment Construction

[0042] In order to solve the problem of how to discover the adjacent serving relay node, the technical solution provided by the embodiment of the present invention is as follows: Each terminal reports to the terminal as the central control point (in the embodiment of the present invention, the terminal as the central control point is called UE_con) For the relay capability information, UE_con determines the terminal that can serve as the adjacent serving relay node according to the relay capability information reported by each terminal, and then, UE_con obtains and sends the identification information of the terminal that can serve as the adjacent serving relay node. A terminal that is not UE_con receives and saves the identification information of a terminal that can serve as a proximity serving relay node. When it is necessary to initiate a relay communication to a communication peer through a proximity serving relay node, it can use the stored proximity serving relay node Th...

Abstract

The invention discloses a proximity-based service relay node discovering method, a terminal and a proximity-based service communication system. The method comprises the following steps: a terminal serving as a central control point obtains identification information of a terminal which can serve as a proximity-based service relay node, the terminal which can serve as the proximity-based service relay node is determined by the terminal serving as the central control point according to terminal-reported relaying capability information, and the terminal serving as the central control point sends the obtained identification information of the terminal which can serve as the proximity-based service relay node. Proximity-based service relay node discovering is realized through the method provided by an embodiment of the proximity-based service relay node discovering method, the terminal and the proximity-based service communication system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a discovery method of a proximity service relay node, a terminal and a proximity service communication system. Background technique [0002] At present, the 3rd Generation Partnership Project (The3rd Generation Partnership Project, 3GPP) Proximity-based Services working item (ProSe) working group is researching the proximity communication technology between devices for commercial and public safety scenarios. . [0003] In the United States, Long Term Evolution (LTE) was selected by the Federal Communications Commission (FCC) as a technology for public safety networks. In Europe, organizations are discussing how to select broadband public safety spectrum. [0004] The consensus reached on proximity communication in public safety scenarios includes the following aspects: [0005] Public safety terminals can work in the public safety spectrum to use public safety s...
