Abstract:
A mobile telecommunication system including at least one transceiver station (BTS1), coupled to a mobile terminal (MT) via a radio links and adapted to exchange mobile information (AAL-SDU: MUD, MSI) with a telecommunication controller (TC: SSC1-2; MSC), said mobile information including a predetermined telecommunication signalling (HOCOM) to be transported to said telecommunication controller,said transceiver station (BTS1) including first mapping and loading means (SART) adapted to map said mobile information into first packets (CPS; AAL-PDU) and to load said first packets into second packets (ATM) to be transmitted to said telecommunication controller,and said telecommunication controller (TC; BSC1-2; MSC) including second mapping and loading means (SARS1; SARS2) adapted to unload said first packets from said second packets,wherein each of said first packets (CPS; AAL-PDU) comprises a payload (PLD1; PLD) and a control part (HD1; TRL),wherein said predetermined telecommunications signalling (HOCOM) is a hand-over command, for said mobile terminal (MT). from a first transceiver station (BTS1) to a second transceiver station (BTS2, STS3),and wherein, in order to avoid having to search through said payload for said predetermined telecommunication signalling, said first mapping and holding means (SART) of said transceiver station (BTS1) is adapted to map said predetermined telecommunication signalling (HOCOM) into a predetermined field (CPS-UUI; CPCS-UU) of the control part of said first packets and to map the remainder of said mobile information (AAL-SDU; MUD, MSI) into the payload of said first packets,and said second mapping and loading means (SARS1; SARS2) of said telecommunication controller (TC; BSC1-2; MSC) is adapted to extract said predetermined telecommunication signalling (HOCOM) from said predetermined field of the control part of said first packets.
