Patent ID: 7139254

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 control channel (BCCH) and a packet-switched broadcast control channel (PBCCH), and at least one mobile station which supports the packet data network and is arranged to listen to at least one of said broadcast control channels, comprising: transmitting the connection set-up parameters of the packet data network to mobile stations in said cell on both 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; indicating said connection set-up parameters of the packet data network to the mobile station in a message which is transmitted on one of said broadcast control channels only; wherein said packet data network is a GPRS system; and the GPRS connection set-up parameters are indicated to the mobile station in an SI13 message which is modified to comprise information on the broadcast control channels of the cell that support the packet data network and which message is transmitted on the circuit-switched broadcast control channel; wherein the information in the SI13 message on the broadcast control channels of the cell that support the packet data network comprises at least one of the following: the cell supports the packet data network on said packet-switched broadcast control channel; the cell does not support the packet data network on said packet-switched broadcast control channel; and the cell supports the packet data network on said packet-switched broadcast control channel and said circuit-switched broadcast control channel.
