Abstract

The invention relates to a grouped data sending method, which comprises the following steps of: receiving grouped data comprising an identifier of a target terminal from a source terminal; finding out whether a path reaching the target terminal exists in a routing cache list; if finding out the path reaching the target terminal exists, carrying out interface selection; and forwarding the grouped data through a selected interface according to the found path. The invention further relates to another two grouped data sending methods corresponding to the grouped data sending method, and a terminal and a base station corresponding to the grouped data sending method. By adoption of the grouped data sending method, the base station and the terminal disclosed by the invention, link treatment can be carried out at the terminal.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method for sending packet data, a base station and a terminal. Background technique [0002] Multi-hop relay is a means to make the network run without a fixed access point. It was first researched and applied in the ad hoc network. The adhoc network has no fixed infrastructure and no fixed routers. All nodes are mobile, and all nodes can dynamically maintain contact with other nodes in any way. All nodes in the network have equal status, and there is no need to set up any central control node. Nodes in the network not only have the functions required by ordinary mobile terminals, but also have message forwarding capabilities. In this environment, due to the limited wireless coverage of the terminal, two user terminals that cannot communicate directly can perform packet forwarding by means of other nodes, that is, multi-hop communication. In recent years, it ha...
