The present invention sets forth techniques for channelizing and encoding various broadcast information services using, for example, a broadcast control channel to provide information to a mobile station user. The mobile station may be a receive-only device, similar to a simple pager, or may be a receive/transmit device, such as a mobile phone. In order to limit the capacity of the broadcast channel that is consumed by, e.g., a Security Quote service, an efficient encoding and channelization method is provided. The method includes separating the short-message-service broadcast control channel into 3 logical sub-channels: a Security Name channel, a Start Value channel and a Delta channel. These channels provide different aspects of the securities information to the mobile station. By varying the bandwidth allocation of these individual channels, the present invention is capable of providing a very large amount of securities while also maintaining a fast cycle time. |
