Method for establishing communication linkage as well as network elements and system thereof

Abstract

The invention provides a method for establishing communication linkage as well as network elements and a system thereof for solving the problem of low standardization level of communication linkage between network elements in a self-organizing network in the prior art. The method mainly comprises the following steps: sending a query message containing target access network entity identification to an intermediate network element; receiving transport layer address information which is acquired by the intermediate network element according to the target access network entity identification and sent by the intermediate network element; and establishing communication linkage with a target access network entity according to the transport layer address information. The method can help improve standardization level of communication linkage between the network elements in the self-organizing network.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, a network element and a system for establishing a communication connection. Background technique [0002] With the development of communication technology, the wireless performance of 3G network has been greatly improved. At present, self-organizing network has appeared. The network self-organization of this network is an important feature, which is of great significance for reducing manual planning and operation. . For example, Long Term Evolution Self Optimized Network (LTE SON, Long Term Evolution Self Optimized Network). In the prior art, when it is necessary to establish a communication connection between two network elements, the premise that must be met is to know the transport layer address information of the other party before the communication connection can be established. For example, cell A finds that cell B belongs to a neighboring cell and there is a ha...

Problems solved by technology

In the prior art, when a communication connection needs to be established between two network elements, the premise that must be met is to know the transport layer address information of the other party before the communication connection can be established. For example, cell A discovers that cell B belongs to a neighboring cell and there is a handover and belong to different network elements, but because there is no communication connection for switching, the switching time is too long. At this time, it is necessary to dynamically create a communication connection between cell A and cell B for switching to achieve the purpose of optimizing the network. self-organization of the network

[0003] At present, the transport layer address is obtained mainly by querying the domain name server (DNS, Domain Name Server) according to the network element identification, but this solution is a private protocol, and the degree of standardization is not high
