A method and system for realizing roaming through an LTE network

Abstract

The invention provides a method and a system for realizing roaming through an LTE (Long Term Evolution) network and relates to the field of mobile communication. The method comprises the steps of receiving power-on attach request signaling transmitted by a mobile terminal; judging the mobile terminal to be an international roaming subscriber according to the power-on attach request signaling, and transmitting the power-on attach request signaling to a home subscriber server of the mobile terminal through an S6a-i interface and an S6a signaling channel established with a global GPRS (General Packet Radio Service) international roaming network, wherein the S6a-i interface is an interface which is connected with the global GPRS international roaming network through the Internet and is used for international roaming; if response signaling fed back by the home subscriber server according to the power-on attach request signaling is received, allowing the mobile terminal to use the international roaming service. The method and the system for realizing roaming through the LTE network solve the problems that equipment for newly establishing international Diameter straight signaling is needed for international roaming in the existing 4G (4-Generation) network, internal long-distance circuits need to be newly added, joint debugging between international operators is needed and the like.

Description

technical field [0001] The invention relates to the technical fields of mobile communication and core network, in particular to a method and system for realizing roaming through an LTE network. Background technique [0002] At present, the public's demand for broadband networks is getting higher and higher, and the LTE (Long Term Evolution) network (including TDD-LTE, FDD-LTE, referred to as 4G network), as a new generation communication mode, is becoming a mobile broadband solution. And quickly attracted the attention of the industry. With the rapid development of LTE in the world, such as North America, Hong Kong, Western Europe and other regions have built and commercialized this service, LTE international roaming is more popular. [0003] Since the technology and equipment involved in the LTE network are quite different from traditional 2G (such as GSM) and 3G (such as WCDMA, TD-SCDMA, and CDMA2000), in order to realize LTE international roaming, major changes and new n...

AI Technical Summary

Problems solved by technology

However, this solution has the following disadvantages: the construction cycle problem, the construction of the LTE network has started or has been completed, but the construction of I-DRA has not yet started or has not been completed; the problem of international joint debugging requires joint debugging between international operators. Due to problems related to international cooperation and management, and many international operators, the progress is generally slow; international transmission issues require the deployment of new international long-distance transmission circuits between operators
