Wireless communication network having a broadcast system for information distribution
First Claim
1. A method of providing a common communication channel for a plurality of user terminals in a user group, the method comprising:
- receiving a respective stream of media data packets from any of the user terminals in the user group;
transmitting received media data packets to the plurality of user terminals in the user group, each transmitted media data packet comprising a source user terminal indicator indicating a user terminal from which the media data packet was received;
receiving the transmitted media data packets at the user terminals; and
at each receiving user terminal, eliminating any media data packets comprising a source user terminal indicator indicating the receiving user terminal before decoding the received media data packets.

Abstract
A communication network (100) includes a two-way communication system (101) having a number of base stations (102-108) providing corresponding coverage areas (110-116) for one or more mobile terminals (148 and 150). In order to minimize congestion of the two-way communication system (101) a broadcast system (118) is included which allows for messages to be transmitted to the mobile terminals (148 and 150). Provision of such a broadcast system frees-up network resources that would otherwise be required to support the transmission of such messages. In one embodiment, the communication network (100) includes a number of information gathering devices such as traffic cameras (126-136) that collect information on traffic conditions within the communication network (100). By determining the location of the mobile terminals (148 and 150) and their intended journey routes, or based upon travel information previously provided to the network, the communication network (100) can transmit via the broadcast system (118) images of traffic conditions along one or more particular travel routes to the mobile terminals (148 and 150). The mobile terminals (148 and 150) include receiver sections for receiving both the messages transmitted by the two-way communication system (101) and the one-way broadcast system (118).
