Method and device for determining communication path

Abstract

The invention discloses a method and device for determining a communication path. The problem that an existing path which is configured for a small cell needing to be connected into a network and directly communicates with a wireless channel between macro stations probably makes transmission efficiency low and transmission time delay lager is solved. The method includes the steps that when a wireless node needs to be connected into the network, an optimal communication path from the wireless node to the network is acquired; the wireless node communicates with the network through the acquired optimal communication path, wherein the optimal communication path instructs the wireless node to be connected into the network through at least one auxiliary node, and the at least one auxiliary node in the auxiliary nodes is a wired node which directly communicates with the network. Due to the fact that the at least one auxiliary node which can provide the data forwarding service function for other nodes is connected into the network and communicates with the network, transmission quality and performance of data between the wireless node needing to be connected into the network and the network are improved, and transmission efficiency of the wireless node is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for determining a communication path. Background technique [0002] In the LTE system, most of the nodes on the network side are connected through wired links, that is, eNBs (base stations) are connected through wired links, eNBs and core network nodes (such as mobility management entities (MME), serving gateways) (Serving Gateway, S-GW) etc.) are also connected by wired links, such as figure 1 shown. [0003] Similarly, in the wireless relay (Relay) architecture, traditional eNBs, eNBs and core network nodes are also connected through wired links, while Relay and its main base station (Donor eNB, DeNB) Communicate via the wireless interface, such as figure 2 shown. [0004] In the future development of the mobile communication system, as the transmission rate and capacity required by users for wireless broadband services are increasing, in ...
