1. Method comprising:
- storing a permanently allocated protocol identifier in a mobile communication device;
powering on the mobile communication device and entering an idle state so that a mobile communication network is not aware of the device;
receiving a transmission from a mobile communication network to the mobile communication device after powering on the device but before the mobile communication network becomes aware of the device due to the device being in an idle state;
in response to the receiving a transmission step, the mobile communication device identifying a matching protocol identifier;
in response to the identifying step, the mobile communication device processing the transmission;
establishing communication between the mobile communication device and the mobile communication network so that the mobile communication network is capable of tracking the mobile communication device;
the mobile communication network dynamically allocating another protocol identifier; and
the mobile communication device receiving and processing at least one other transmission from the mobile communication network that contains the another protocol identifier.

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 sub-network 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 while other identifiers are dynamically assigned to other PDPs by the network.
