TRANSMITTING CONTROL MESSAGES ON CONTROL CHANNELS OF PACKET DATA NETWORK

摘要

A method for transmitting control messages of a packet data network in a telecommunications system which comprises at least one cell, in which said control messages are arranged to be transmitted on a circuit-switched broadcast control channel, a packet-switched broadcast control channel and a traffic channel. In addition, the telecommunications system comprises at least one mobile station which supports the packet data network and is arranged to lis-ten to at least one of the broadcast control channels. First control messages to be transmitted on a packet-switched channel of the packet data network are transmitted to the mobile stations in said cell encapsulated inside a second control message if the cell supports the transmission of the connection set-up parameters of the packet data network on both a circuit-switched broadcast control channel and a packet-switched broadcast control channel.
