Embodiment Construction

[0050] The network structure of a cellular wireless local area network mobile multimedia communication system proposed by the present invention is as follows: figure 1 As shown, this is the networking method when multiple countries adopt the system of the present invention. In this application mode, the entire network is composed of an international toll network 11, a routing device 12, several domestic toll networks 13, a routing device 14, several local networks 15, and several subnets 16. When communicating between terminals in the same subnet, information flows within the subnet. When terminals in two subnets of the same local network communicate, information flow flows from one subnet 16 to the local network 15 , and then flows from the local network 15 to another subnet 16 . The information flow in the opposite direction takes the exact opposite route. When communicating between terminals of different local networks of the same domestic long-distance network, the infor...

Abstract

This invention refers to a cellular WLAN mobile multimedia communication system and method in mobile communication technology, system contains four grades, sub-network, local network, national trunk network and internal trunk network, method contains system searching, IP address distributing, register attestation, standby, communication and exit. Said invention solves the quick switching problem of wireless terminal moving in large range and keeping wireless terminal in continuing multimedia communication. Said invention adopts all IP network structure and E 164 format standard telephone number as terminal identifying code with low cost and large capacity.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a cellular wireless local area network mobile multimedia communication system and method which applies IP transmission technology to mobile communication. Background technique [0002] All current public mobile communication systems, such as GSM mobile communication system, CDMA mobile communication system, third generation mobile communication system (3G), etc., are based on circuit switching technology. The IP services they provide are also based on circuit-switched transmission channels, and the bandwidth is relatively narrow. Therefore, these systems have relatively poor support for multimedia communications, and the system capacity is also limited. [0003] The inventive system uses the broadband wireless local area network as the access means and the broadband IP network as the transmission platform to form a broadband public mobile communication system with an...
