Abstract

The invention relates to a method for realizing train terminal multi-media service based on GPRS mobile intelligent network; the method solves the problems that the service items are monotonous, lack characteristics and have low information degree in the existing passenger train; the invention provides a method for realizing train terminal multi-media service based on GPRS mobile intelligent network; firstly, a train mobile terminal multimedia service supporting network structure is designed, and then flows of five parts of the train mobile terminal multi-media service are realized according to network definition: user terminal starting-up flow, user terminal access network flow, shopping and meal-ordering flow in the train, and the process that the user terminal is departed from the network and the charging process; by utilizing the functions provided by the GPRS mobile intelligent network, users can carry out video on demand, wireless internet, shopping in the train and dish ordering and other service by the operation of the mobile terminal, meanwhile, service staffs in the train can receive service request of passengers by a server an carry out service pertinently.

Description

technical field [0001] The invention relates to a method for realizing multimedia services of a train terminal based on a GPRS mobile intelligent network, which belongs to the field of mobile communication. Background technique [0002] GPRS (General Packet Radio Service) mobile intelligent network refers to a layer of network superimposed on the original GPRS network on the basis of complying with the CAMEL3 (Mobile User Enhanced Logic Customization Application Phase 3) protocol, so that it can be quickly and conveniently , Economical, flexible and effective generation and realization of various new GPRS intelligent data services. [0003] In the GSM-R (Railway Mobile Communication) network, the intelligent network has been applied in the circuit domain, but the application in combination with the packet network has stagnated. CAMEL3 stipulates the interconnection between intelligent network and GPRS, which can extend the scope of application from the current voice service...
