Abstract

The invention relates to a multimode access gateway and an access method applicable to a TD-LTE (Time Division-Long Term Evolution) broadband communication system of high speed railway. The multimode access gateway comprises a protocol forward module, a routing forward module, a network address translation module and a start initialization module. The invention aims to the feature that high speed railway trains support the access of various communication technology systems, the TD-LTE broadband communication system of the high speed railway can assess to 2G / 3G and Internet heterogeneous networks, and the problem of data routing forwarding between the TD-LTE system and the heterogeneous networks is solved, so that the transmission rate of the whole broadband communication system is improved, and the correct transmission of service data is ensured.

Description

technical field [0001] The invention relates to a multi-mode access gateway and an access method suitable for a high-speed railway TD-LTE broadband communication system, belonging to the communication field. Background technique [0002] With the continuous development of my country's high-speed railway construction, high-speed trains have become an important means of transportation for passengers to travel long distances. At the same time, passengers have increasingly urgent needs for high-quality communication and digital entertainment services on high-speed trains. At present, foreign countries combine satellite technology, GPRS (General Packet Radio Service) and UMTS (Universal Mobile Telecommunications System) technology with WiFi wireless network to provide uninterrupted wireless broadband Internet connection on cross-border trains with a speed of up to 300km / h; and Someone proposed a train operation control network based on WiMAX technology to replace the existing GSM...
