Method, system and device for realizing stream media service

The invention discloses a method for realizing streaming media service, which comprises the steps that: an adaptive control entity receives a streaming media service request comprising user information and the information of the streaming media service sent by the user; if user authentication and service order are determined to be successful, a internally established strategic program of the adaptive control entity is utilized to analyze and determine a terminal and access mode currently most suitable for receiving the streaming media service for the user; negotiation with the user is carriedout; the streaming media service is transmitted to the user by the terminal and access mode obtained by negotiation; during the transmission process of the streaming media service, if the adaptive control entity monitors the occurrence of a trigger event, new adaption is triggered; the streaming media service continues to be transmitted to a new terminal and access mode, and the original transmission ...

Network terminal selection method and device in heterogeneous network

The invention relates to a network terminal selection method and a device in a heterogeneous network. The method selects the most suitable network to be accessed through collecting network information, user information, terminal information and service information of usable candidate networks, and selects the most suitable terminal in the selected network to execute the switching of the terminal or the switching of the network and the terminal. The invention changes emphasis on personal mobility from previous terminal mobility, enables a user to connect with a plurality of single mode/multiple mode terminals, innovatively considers a user terminal selection proposal and realizes terminal intelligent switching at the same time of network selection. Simultaneously, in order to enable the network selection to satisfy the demands of users and services to the maximum, the invention introduces a plurality of parameters in the aspect of networks, terminals, users and services, and uses a simplified ...
