Patent ID: 7020481

Claim:
A method for transmitting connection set-up parameters of a packet data network on broadcast control channels in a telecommunications system, which comprises at least one cell which uses a circuit-switched broadcast/common control channel (BCCH/CCCH) and a packet-switched broadcast/common control channel (PBCCH/PCCCH), and at least one mobile station which supports the packet data network and is configured to listen to at least one of said broadcast/common control channels, comprising transmitting the connection setup parameters of the packet data network to mobile stations in said cell on both said circuit-switched and said packet-switched broadcast control channels in response to the fact that the cell supports the transmission of the connection set-up parameters of the data packet network on both the circuit-switched broadcast control channel and the packet-switched broadcast control channel, transmitting from the mobile station to the packet data network a dual control channel mode (DCCM) indication in response to the fact that said mobile station is capable of receiving control messages on both said common control channels, subsequently to said two transmitting steps, selecting, in response to said DCCM indication, one of said common control channels for transmission of control messages to said mobile station, and directing said telecommunications system to transmit control messages to said mobile station on the selected one of said common control channels.
