WIRELESS COMMUNICATIONS APPARATUS, METHODS AND COMPUTER PROGRAM PRODUCTS USING BROADCAST CHANNEL MESSAGING FOR APPLICATION TRANSPORT

摘要

First, second and third classes of Packet System Information PSI messages are transmitted on a Packet Broadcast Control Channel PBCCH of a General Packet Radio Service GPRS wireless mobile packet data communications system at respective first, second and third repetition rates. The PSI messages of the third class may comprise Extremely Low Repetition ELR Payload messages including embedded information from an application layer, such as a Location Services LCS application layer or a Short Message Service Cell Broadcast SMSCB application. Transport layer messages for such an application may also be transmitted on a logical subchannel defined on a Packet Common Control Channel PCCCH.
