ABSTRACT:
A mobile telecommunication system with Base Transceiver Stations (BTS1-3) coupled to a mobile terminal (MT) via a radio link and exchanging mobile information (AAL-SDU: MUD, MSI) with a telecommunication controller (TC: BSC1-2; MSC). The mobile information contains a telecommunication signaling, such as a hand-over command (HOCOM), e.g. to be transported to the telecommunication controller. According to the ITU recommendation for the ATM Adaptation Layer AAL of the type 2 or 5, the AAL-PDU packets, which may for instance be transported by ATM cells, and wherein the mobile information is mapped, include a User-to-User indication field CPS-UUI or CPCS-UU, respectively, that transparently transports user data. This field is used to transport the telecommunication signaling in the up-link connection to a Base Station Controller (BSC1-2) or to a Mobile Services switching center (MSC), or, in the down-link connection, to base transceiver station (BTS1-3). The circuit (SARS1-2) which extracts this telecommunication signaling is relatively simple since the location of this signaling in the packet is well known because it corresponds to the location of the user-to-user indication field. There is thus no need, for the circuit (SARS1-2) receiving a packet, to search for the telecommunication signaling in the whole packet received.
