Abstract:
1. 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 configured to be transmitted on a circuit-switched broadcast control channel (BCCH), a packet-switched broadcast control channel (PBCCH) and a traffic channel (PDTCH), and at least one mobile station which supports the packet data network and is configured to listen to at least one of said broadcast control channels, comprising: transmitting to the mobile stations in said cell a packet system information message to be transmitted on a packet-switched channel of the packet data network encapsulated inside a control message in response to the fact that 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; indicating by a field in said control message that said packet system information message is encapsulated inside said control message; and rejecting said packet system information message in the mobile station in response to the fact that said mobile station is configured to listen to the circuit-switched broadcast control channel and said control message comprises said field indicating encapsulation.
