Connection establishment method and user equipment
First Claim
1. A connection establishment method, comprising:
- acquiring, by a second user equipment supporting a device to device (D2D) function, first user equipment information of a first user equipment supporting the D2D function;
determining, by the second user equipment, to establish a connection with the first user equipment according to the first user equipment information; and
initiating, by the second user equipment, after determining to establish the connection with the first user equipment, a connection establishment process with a network-side device and sending the first user equipment information to the network-side device in the connection establishment process to facilitate establishment of a connection between the network-side device and the first user equipment;
wherein after a connection is established between the network-side device and the first user equipment, the method further comprises;
receiving, by the second user equipment, a D2D link establishment request message from the first user equipment, wherein the D2D link establishment request message carries an identifier of the first user equipment, an identifier of the second user equipment, and channel state information and resource allocation condition of the first user equipment; and
sending, by the second user equipment, a D2D link establishment response message to the first user equipment if connection establishment is permitted, wherein the D2D link establishment response message carries the identifier of the second user equipment, the identifier of the first user equipment, channel state information of the second user equipment and an accepting or rejecting response of the second user equipment to the resource allocation condition of the first user equipment.
