Embodiment Construction

[0022] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0023] Based on the domain name system (DNS) resolution method, DNS equipment is introduced to realize the translation function of SCTP coupling and TA mapping through DNS. At this time, the SGs interface between MME and MSC SERVER does not need to be manually established statically, and all configurations are realized through DNS translation.

[0024] The SGs interface is the interface between the SGSN and the mobile softswitch node MSC SERVER. Through this first interface, the SGSN sends the location information of the mobile user to the MSC SERVER and receives the paging request from the MSC SERVER at the same time.

[0025] An embodiment of the present invention provides a method for establishing an interface between heterogeneous networks, which is ...

Abstract

The embodiment of the invention provides a method for building an interface between heterogeneous networks, MME (mobile management equipment) and the heterogeneous networks. The method is used for the MME, a first interface SGs is built between the MME and an MSC SERVER (mobile switching center server), and the MME launches inquiries to a DNS (domain name system) to obtain an IP (internet protocol) address and a port number of the MSC SERVER corresponding to the built first interface; the MME as well as the MSC SERVER builds stream control transmission protocol coupling according to the IP address and the port number; the MME launches a service procedure on stream control transmission protocol coupling, the IP address, a port and terminal information of the MME are recorded by the MSC SERVER, and connection of the service procedure is built. DNS equipment is introduced, translation of SCTP coupling and translation of TA (tracking area) mapping are achieved through the DNS, and the number of SGs interfaces is reduced.

Description

technical field [0001] The invention relates to heterogeneous network technologies, in particular to a method for establishing interfaces between heterogeneous networks, mobility management equipment and heterogeneous networks. Background technique [0002] At present, LTE network (TDD, FDD) is becoming the development trend of the communication industry. In order to solve the voice problem of the terminal, CSFB technology is an important solution recommended by 3GPP. Globally, major mainstream operators have successively deployed CSFB (Circuit Switched Fallback) to provide voice services. In CSFB technology, it is necessary to open the SGs interface between the mobile softswitch node (MSC SERVER, Mobile Switching Center Server) of the 2G&3G network and the mobility management equipment (MME) of the 4G network. The protocol level of the SGs interface is SGsAP / SCTP / IP. [0003] At present, the implementation of SGs interface is based on static configuration-manual configura...
