Embodiment Construction

[0032] The application layer device in the embodiment of the present invention obtains and stores the subscription information of each terminal, the mapping relationship between the internal identifier and the external identifier, and location information; after receiving the proximity relationship discovery request of the first terminal, according to the corresponding Proximity relationship signing information, to determine that the first terminal has the function of being able to discover other terminals; and to determine whether the second terminal and the first terminal meet the proximity principle, and send the judgment result to the first terminal, thus solving the current problem of mutual proximity The problem of a solution for proximity discovery between user devices.

[0033] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] see Figure 4 As shown, a method for determining a pro...

Abstract

The invention discloses a method for determining the proximity relation between user equipment, equipment and a communication system, and is to solve the problem that at present, a solution scheme for finding the proximity relation between mutually-adjacent user equipment is still unavailable. The method of an embodiment in the invention comprises the following steps: the application layer equipment obtaining and storing subscription information, mapping relation between internal identification and external identification as well as position information of each terminal; after receiving a proximity relation discovery request of a first terminal, determining the first terminal has a function of being capable of finding other terminals based on the subscription information corresponding to the first terminal; and judging whether a second terminal and the first terminal accord with the proximity principle, and sending the judgment results to the first terminal. The embodiment of the invention provides the scheme for determining the proximity relation between the user equipment; discovery process of the proximity relation between the user equipment is realized; and with the scheme, a network architecture in an existing protocol is modified less, and the scheme is easy to realize.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device and communication system for determining the proximity relationship between user equipments. Background technique [0002] For the communication process between two user equipment (User Equipment, UE) defined in the current 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP), see figure 1 As shown, the process of UE1 sending data to UE2 includes: [0003] UE1 sends data to eNB1 serving it; eNB1 passes the data to Serving Gateway (Serving Gateway, SGW) / Packet Data Network Gateway (PDN GW) after receiving the data; SGW / PGW receives the data After receiving the data, route the data to the SGW / PGW serving UE1 according to the routing identifier of UE1; since the SGW / PGW of UE1 and UE2 in the figure are the same, the SGW / PGW serving UE2 transfers the data to the SGW / PGW serving UE2 Finally, eNB2 transmits the data to ...
