Embodiment Construction

[0026] The present invention provides a solution to establish a direct communication path between two neighboring UEs. Wherein, after receiving the request message for establishing direct communication between the calling user and the called user, the eNB where the calling user resides allocates a direct communication user plane path identifier for the calling user and the called user, and assigns a direct communication user plane path identifier to the calling user Assign air interface resource configuration information to the direct communication path between the called user and the called user; then send the assigned direct communication user plane path identifier and air interface resource configuration information to the calling user and the called user respectively, and instruct the calling user and the called user Perform bearer configuration. Through the embodiments of the present invention, it is possible to establish a direct communication path between two adjacent U...

Abstract

The invention discloses a method, equipment and system for establishing a direct communication path. The method includes: after the base station where the calling user resides receives a request message for establishing direct communication between the calling user and the called user, allocates a direct communication user plane for the calling user and the called user Path identification, and allocate air interface resource configuration information for the direct communication path between the calling user and the called user; the base station where the calling user resides sends the assigned direct communication path to the calling user and the called user respectively communication user plane path identifier and air interface resource configuration information, and instruct the calling user and the called user to perform bearer configuration. Through the embodiments of the present invention, it is possible to establish a direct communication path between two adjacent UEs so that user plane data transmission between adjacent UEs does not require the participation of the core network, reducing communication delay and network resource occupation.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and system for establishing a direct communication path. Background technique [0002] The communication process between two user equipment (User Equipment, UE) defined in the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, 3GPP): UE1 sends data to the eNB of the service, and the eNB will pass the data to the service The core network devices Serving GW and PGW, PGW will route data to UE2’s serving PGW and Serving GW according to UE1’s routing table, and UE2’s Serving GW will transfer the data to UE2’s eNB, and then pass it to UE2 through eNB. figure 1 Shown is the scenario when the Serving GW and PGW served by UE1 and UE2 are the same. In this scenario, the process of routing data from the PGW serving UE1 to the PGW serving UE2 is not required. [0003] Even if the two communicating UEs are very close to each other, the ...
