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.

7. Apparatus for use in a mobile communication system supporting radio data transmission in a number of different packet data protocols including a point-to-multipoint-multicast protocol, where the protocol is identified by a protocol identifier transmitted between network and said apparatus, the apparatus comprising:
-
a memory for permanently allocating a specific unique value of a protocol identifier to point-to-multipoint-multicast protocol, said memory for storing the permanently allocated point-to-multipoint-multicast protocol identifier, and a signal processor for determining whether a transmission from network contains said point-to-multipoint-multicast protocol identifier and for consequently receiving and processing said transmission. - View Dependent Claims (8, 9, 10)
