Abstract

The invention relates to a method for the comfortable and consistent administration of subscriber-specific data and call processing features of a plurality of Multimedia Terminal Adapters of individual cable network telephony subscribers that are connected via one cable modem each to a broadband cable network used as the telephony access network in conjunction with at least one packet-based exchange for providing network and subscriber features, for processing signaling information and controlling the useful data transfer between the subscribers using suitable packet-based protocols. The method is furthermore characterized by a function that, for example, automatically provides a new cable network telephony subscriber with an allocation to a line unit of the exchange. This function also makes it possible for other telephony-relevant data and address positions to be input in a coordinated manner into the broadband cable network and the exchange. The allocation of the port address for the Multimedia Terminal Adapter of a cable network telephony subscriber to a line unit of the exchange can be carried out by the exchange itself, by a superordinate Network Management System and/or in the framework of a preconfiguration by means of at least one planning and configuration tool of the network provider upstream of the Network Management System. The advantages of the inventive system consist mainly in releasing the network provider from any call processing-specific additional addressing of cable network subscribers and in allowing for a decomposition of symbolic addresses during start or restart of the exchange, expired period of validity of the addresses or in the failure mode.

Claims

1-22. -22. (canceled)

23. A method for managing subscriber data of a subscriber connected via a cable modem to a broadband cable distribution network used as a telephone access network with a packet-based exchange, comprising:

automatically assigning the subscriber to a connection interface location of the exchange;

removing a connection interface location element that is unassigned from a connection interface location pool when the subscriber is set up;

returning the connection interface location element when the subscriber is removed from the network; and

assigning a port address of the subscriber at a multimedia terminal adapter to the connection interface location via a network management system, or specified by the port address via a preconfiguration by a planning and configuration tool of a network operator.

24. The method as claimed in claim 23, wherein a fixed address that identifies the multimedia terminal adapter and a data set are entered into the network management system.

25. The method as claimed in claim 24, wherein the data set describes the subscriber.

26. The method as claimed in claim 25, wherein the data set includes the connection interface location.

27. The method as claimed in claim 23, wherein the network management system specifies a cable modem terminal system and the exchange.

28. The method as claimed in claim 23, wherein the network management system assigns a telephone profile and generates a subscriber packet address information from a location of the connection interface at the multimedia terminal adapter and a fixed address of the multimedia terminal adapter.

29. The method as claimed in claim 28, wherein a physical packet address is allocated to each port of each multimedia terminal adapter as the subscriber packet address information.

30. The method as claimed in claim 28, wherein a physical packet address assigned to the multimedia terminal adapter and supplemented by a port index which is used for a subscriber-specific signaling is allocated to each port of the multimedia terminal adapter as the subscriber packet address information.

31. The method as claimed in claim 28, wherein an individual symbolic address in a packet network is allocated to each port of each multimedia terminal adapter as the subscriber packet address information.

32. The method as claimed in claim 31, wherein the individual symbolic address is selected in accordance with a standard naming convention and references a symbolic name of the multimedia terminal adapter and a port index.

33. The method as claimed in claim 32, wherein the network management system loads the subscriber data into the exchange.

34. The method as claimed in claim 33, wherein the subscriber data includes a subscriber port address.

35. The method as claimed in claim 33, wherein the subscriber data is loaded using the connection interface location.

36. The method as claimed in claim 33, wherein the subscriber data is loaded using a subscriber port address.

37. The method as claimed in claim 33, wherein the exchange includes a preconfigured table for converting the connection interface location and the port address.

38. The method as claimed in claim 23, wherein subscriber-relevant information is available to the broadband cable network via the network management system.

39. The method as claimed in claim 38, wherein the subscriber-relevant information includes a telephone profile of the subscriber, the connection interface location of the subscriber at the multimedia terminal adapter, a fixed address which identifies the multimedia terminal adapter, and a packet address of the subscriber and of the exchanges.

40. The method as claimed in claim 39, wherein the packet address is selected from the group consisting of physical address and symbolic address.

41. The method as claimed in claim 40, wherein during the startup of the exchange, administration, or when putting the multimedia terminal adapter into service, the symbolic address are decomposed into the physical addresses via a DNS server.

42. The method as claimed in claim 23, wherein the address conversion of a signaling data packet within the exchange takes place in a peripheral part of the exchange that is oriented toward the subscribers.

43. The method as claimed in claim 23, wherein when replacing the multimedia terminal adapter, only a new terminal adapter address is specified to the network management system with reference to a previously associated packet address.

44. The method as claimed in claim 23, wherein a plurality of internet protocol addresses are used as the packet addresses of the multimedia terminal adapters and their ports and the exchange.

45. The method as claimed in claim 23, wherein a protocol-assured communication interface or a data interface provides an interface between the network management system, the broadband cable distribution network, and between the network management system and the exchange.

46. The method as claimed in claim 23, wherein the symbolic addresses are decomposed during a startup or restart of the exchange.

47. The method as claimed in claim 23, wherein an alternative access of a cable network subscriber is provided to a plurality of exchanges.

48. An administration system of subscriber data and call processing features, comprising:

a network management system connected to a packet-based exchange and a broadband cable distribution network;

a multimedia terminal adapter included in the broadband cable distribution network;

a subscriber connected via a cable modem to the broadband cable distribution network;

a connection interface location of the exchange which is automatically assigned to the subscriber;

a connection interface location pool including a connection interface location element;

the element is removed from the pool when it is assigned to the subscriber, the element is returned to the pool when it is unassigned from the subscriber; and

a port address of the subscriber at the multimedia terminal adapter is assigned to the connection interface location via the network management system.

49. The system as claimed in claim 48, wherein the port address is preconfigured by a planning and configuration tool of a network operator.
