Method for Providing Functionality of an Exchange Termination Unit and a Line Termination Unit in a Communication Network

1 . A method for providing of an operating and maintenance function in a communication network (NW) that comprises on the subscriber side an ISDN-network and on the transport side at least one packet-oriented network (NGN), with a gateway (AGW) and a media gateway controller (GWC) being arranged at the transport-side end of the ISDN network with the functionality of the exchange termination unit (ET) and of the line termination unit (LT) being implemented in the gateway (AGW) and/or in the media gateway controller (GWC).

2 . (canceled)

3 . The method according to claim 1 , wherein

functions (OAM) for at least one of operation, administration and maintenance in the time-multiplex-oriented communication network (ISDN) are realized in the exchange termination unit (ET) and line termination unit (LT) for transmission of information within the time-multiplex-oriented communication network (ISDN).

4 . The method according to claim 1 , wherein

the functionality of the exchange termination unit (ET) is implemented in the media gateway controller (GWC) and the functionality of the line termination unit (LT) is implemented in the access gateway (AGW).

5 . The method according to claim 1 , wherein

the packet-oriented communication network (NGN) is realized according to at least one of the Internet protocol (IP), SIP and ATM.

6 . The method according to claim 1 , wherein

the time-multiplex-oriented partial network (ISDN) is one of an ISDN network and a number of ISDN-SSist.

7 . The method according to claim 3 , wherein

the functions (OAM) for operation, administration and maintenance are essentially performed according to at least one of standard ETSI ETS 300 011, standard ITU-T G.962 and standard ETSI ETS 300 233.

8 . A communication network (NW) for exchange of information that transmits the information on a subscriber side via at least one time-multiplex-oriented partial network (ISDN) and on a transport side via at least one packet-oriented partial network (NGN), with a gateway (AGW) and a media gateway controller (GWC) being arranged at the transport-side end of the time-multiplex-oriented partial network (ISDN), with the functionality of an exchange termination unit (ET) and of a line termination unit (LT) being implemented in at least one of the gateway (AGW) and the media gateway controller (GWC).

9 . (canceled)

10 . A method for providing a functionality of an exchange termination unit (ET) and a line termination unit (LT) in a communication network (NW) that on a subscriber side has at least one time-multiplex-oriented partial network (ISDN) and on a transport side at least one packet-oriented partial network (NGN), with a gateway (AGW) and an SIP server being arranged at the transport-side end of the time-multiplex-oriented partial network (ISDN), with the functionality of the exchange termination unit (ET) and of the line termination unit (LT) being implemented in at least one of the gateway (AGW) and the SIP server.

11 . The method according to claim 10 , wherein functions (OAM) for at least one of operation, administration and maintenance in the time-multiplex-oriented communication network (ISDN) are realized in the exchange termination unit (ET) and line termination unit (LT) for the transmission of information within the time-multiplex-oriented communication network (ISDN).

12 . The method according to claim 10 , wherein the packet-oriented communication network (NGN) is realized according to at least one of the Internet protocol (IP), SIP and ATM.

13 . The method according to claim 10 , wherein the time-multiplex-oriented partial network (ISDN) is one of an ISDN network and a number of ISDN-SSist.

14 . The method according to claim 11 , wherein the functions (OAM) for operation, administration and maintenance are essentially performed according to at least one of standard ETSI ETS 300 011, standard ITU-T G.962 and standard ETSI ETS 300 233.
