Abstract
A method of operating a mobile communication system supporting data transmission between a mobile station (MS) and a network in a number of 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.

12. A first entity, for use in a mobile communication system supporting radio data transmission between the first entity and a second entity in a number of different packet data protocols (PDPs) including a point-to-multipoint-multicast (PTM-M) protocol, where the protocol is identified by a protocol identifier transmitted between the first entity and the second entity, said system comprising:
-
means for permanently allocating a specific unique value of a protocol identifier to PTM-M transmissions, wherein said first entity 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.
