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

Abstract

A method, a network element and a system for establishing the communication connection are provided for solving the problem that the standardization degree of the communication connection between the network elements for realizing self-organized network is not high in the prior art. The method includes: query information including the identification of the object access network entity is sent to a mobile management entity MME; transport layer address information sent from the MME is received; and the transport layer address information is obtained by the MME according to the identification of the object access network entity; the communication connection between the network elements in the self-organized network.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a method, network element and system for establishing a communication connection. Background technique [0002] With the development of communication technology, the wireless performance of 3G networks has been greatly improved. At present, self-organizing networks have emerged. The network self-organization of the network is an important feature and is of great significance for reducing manual planning and operation. . For example, Long Term Evolution Self Optimized Network (LTE SON). In the prior art, when a communication connection needs to be established between two network elements, the prerequisite that must be met is that the transmission layer address information of the other party must be known before the communication connection can be established. For example, cell A finds that cell B belongs to a neighboring cell and has a handover It belongs to different network ele...

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
