Abstract
A method of operating a mobile communication system supporting data transmission between a mobile station (MS) and a network in a number of a different packet data protocols (PDPs) including a point-to-multipoint-multicast (PTM-M) protocol. PDP data is formatted and unformatted by a subnetwork dependent convergence protocol (SNDCP) according to the PDP of data. The PDP is identified to the SNDCP by a protocol identifier transmitted between the network and the mobile station. In order to allow a MS to receive a PTM-M in an IDLE state, a unique protocol identifier is permanently assigned to PTM-M transmissions whilst other identifiers are dynamically assigned to other PDPs by the network.

A method of operating a mobile communication system supporting radio data transmission between a mobile station (MS) and a network in a number of different packet data protocols (PDPs) including a point-to-multi-point-multicast protocol (PTM-M), where the protocol is identified by a protocol identifier transmitted between the network and the mobile station, the method comprising the steps of:
- permanently allocating a specific unique value of a protocol identifier to PTM-M packet data protocol;
- and
- dynamically allocating other protocol identifier values to other packet data protocols.
Apparatus comprising means for operating a mobile communication system supporting radio data transmission between a mobile station and a network in a number of different packet data protocols including a point-to multipoint-multicast (PTM-M) protocol, where the protocol is identified by a protocol identifier transmitted between the network and the mobile station, and means for permanently allocating a specific unique value of a protocol identifier to PTM-M transmissions and for dynamically allocating other protocol identifier values to other protocols.
A mobile communication device, for use in a mobile communication system, supporting radio data transmission between the mobile communication device and a network in a number of different packet data protocols (PDPs) including a point-to-multipoint-multicast protocol (PTM-M), where the protocol is identified by a protocol identifier transmitted between the network and the mobile communication device, said system comprising:
- means for permanently allocating a specific unique value of a protocol identifier to PTM-M transmissions;
- and
- means for dynamically allocating other identifier values to other protocols;
- and wherein said mobile communication device comprises:
- a memory for storing the permanently allocated PTM-M protocol identifier, and
- signal processing means for determining whether a transmission from the network contains said PTM-M protocol identifier and for consequently receiving and processing said transmission.
