Abstract
Techniques for use in communicating messages to a mobile device operative in a wireless network are described. A communication network receives a broadcast message which includes a protocol type identifier in a protocol type identifier field. The communication network identifies whether the protocol type of the broadcast message matches one of a plurality of protocol types stored in association with an identification of the mobile device. If the protocol type of the broadcast message matches one of the stored protocol types, then the communication network produces, from the broadcast message, a unicast message which includes information from the broadcast message, and causes the unicast message to be sent to the mobile device in the wireless network.
