A METHOD FOR PROVIDING REAL-TIME BROADCAST SERVICE IN THE MOBILE COMMUNICATION NETWORK

摘要

This invention relates to a method for providing real−time broadcast service in the mobile communication network, in particular, it adapts to expand real time broadcast service in the third generation of CDMA mobile communication system. Including: the broadcast service layer is added for providing real−time broadcast service in the wireless access network which has original service layer, such as voice call, real−time broadcast service which access mobile communication network broadcasts in real−time to mobile terminal over the air of the mobile communication network, by setting dedicated resource of broadcast, i.e. dedicated carrier or dedicated scrambling code. The mobile terminal operates in two switchable modes of the original service layer and the broadcast service layer. When dedicated carrier is adopted, down carrier frequence is only configured in the broadcast service layer, the mobile terminal controls the cell handoff when mobile terminal moves in cells, and monitors paging. When dedicated scrambling code is adopted, down scrambling code of original service layer and the new down dedicated scrambling is used in the cell of each original service layer added the broadcast service layer.
