Abstract

Methods and apparatus are described for providing fixed terminal access to a mobile telecommunications network in which subscriber'"'"'s mobile stations in the mobile telecommunications network and the fixed terminals are addressable with subscriber information references of the mobile telecommunications network. The fixed terminals are connected to a local loop of a wireline network. An interface unit is provided between the mobile telecommunications network and the wireline network at a node of the mobile telecommunications network. Services of the mobile telecommunication network to and from a subscriber'"'"'s fixed terminal are provided through the interface and the wireline network. The wireline network may be a public service telephone network.

providing a first interface unit between the mobile telecommunications network and a wireline network;

providing a fixed terminal of a subscriber of the mobile telecommunications network, the fixed terminal being addressable with a subscriber information reference of the mobile telecommunications network and being connected to a local loop of the wireline network; and

providing services of the mobile telecommunication network to and from the subscriber'"'"'s fixed terminal through the first interface and the wireline network;

wherein mobile services in a mobile telecommunications network format from the mobile telecommunications network are encapsulated by the first interface unit in a wireline network format and are transmitted transparently through the wireline network.

2. A method according to claim 1, further comprising a second interface unit between the wireline network and the fixed terminal of a subscriber of the mobile telecoununications network and providing mobile telecommunication network services through the first and second interfaces and the wireline network.

3. A method according to claim 1, wherein the first interface unit is connected between a mobile switching center of the mobile telecommunications network and the wireline network.

4. A method according to claim 2, wherein the wireline network is a PSTN and the first and second interface units are each provided a directory number within the PSTN.

5. A method according to claim 4, wherein the provision of services includes routing calls from the subscriber'"'"'s fixed terminal destined for the mobile telecommunications network and routing calls to th subscriber'"'"'s fixed terminal from the mobile telecommunications network through the first interface unit and the wireline network.

6. A method according to claim 5, further comprising routing calls from the subscriber'"'"'s fixed terminal destined for the mobile telecommunications network and routing calls to the subscriber'"'"'s fixed terminal from the mobile telecommunications network through the first and second interface units and the wireline network.

7. A method according to claim 4, wherein each wireline of the PSTN includes one or more bearer channels and a data channel and data channel messages from the PSTN are terminated at the second interface unit.

8. A method according to claim 7, wherein the second interface unit is connected to an S/T bus and the second interface unit converts incoming messages from the PSTN to S/T bus format and converts outgoing messages from the S/T bus format to a PSTN format.

9. A method according to claim 8, wherein the second interface unit assigns data and bearer messages from the PSTN to appropriate channels on the S/T bus.

10. A method according to claim 1, wherein at least portions of messages from the mobile telecommunications network are encapsulated by the first interface unit so that they are transmitted transparently through the wireline network.

11. A method according to claim 2, wherein at least portions of the messages from the fixed subscriber terminal are encapsulated by the second interface unit so that they are transmitted transparently through the wireline network.

12. A method according to claim 8, wherein at least portions of messages from the mobile telecommunications network are encapsulated by the first interface unit so that they are transmitted transparently through the wireline network.

13. A system for extending a mobile telecommunications network by providing fixed terminal access thereto, comprising:

a first interface unit between the mobile telecommunications network and a wireline network;

a fixed terminal of a subscriber of the mobile telecommunications network, the fixed terminal being addressable by a subscriber information of the mobile telephone network and being connected to the local loop of the wireline network; and

the first interface unit having means for transmitting mobile network services for the subscriber'"'"'s fixed terminal through the first interface unit and the wireline network;

wherein the first interface unit is adapted to encapsulate mobile services in a mobile telecommunications network format from the mobile telecommunications network in a wireline network format so that it is transmittable transparently through the wireline network.

14. A system according to claim 13, further comprising a second interface unit between the wireline network and the fixed terminal of a subscriber.

15. A system according to claim 13, wherein the first interface unit is connected between a mobile switching center of the mobile telecommunications network and the wireline network.

16. A system according to claim 14, wherein the wireline network is a PSTN and the first and second interface units are each provided with a directory number within the PSTN.

17. A system according to claim 16, further comprising means for routing calls from the subscriber'"'"'s fixed terminal destined to the mobile telecommunications network and routing calls to the subscribers fixed terminal from the mobile telecommunications network through the first and second interface units and the wireline network.

18. A system according to claim 16, wherein each wireline of the PSTN includes one or more bearer channels and a data channel and the second interface unit includes a terminator for the data channel messages from the PSTN.

19. A system according to claim 18, where in the second interface unit is connected to an S/T bus and the second interface unit is adapted to convert incoming messages from the PSTN to S/T bus format and outgoing messages from the S/T bus format to an appropriate PSTN format.

20. A system according to claim 19, wherein the second interface unit is adapted to assign data and bearer messages from the PSTN to appropriate channels on the S/T bus.

21. A system according to claim 14, wherein the second interface unit is adapted to encapsulate at least a portion of a message from the fixed subscriber terminal so that it is transmittable transparently through the wireline network.

22. A system according to claim 19, wherein the first interface unit is adapted to encapsulate at least a portion of a message from the mobile telecommunications network.

23. A system according to claim 19, wherein the second interface unit is adapted to encapsulate at least a portion of a message from the fixed subscriber terminal so that it is transmittable transparently through the wireline network.

24. An interface unit for connection between a fixed terminal at a subscriber'"'"'s premises and a wireline network, the interface unit comprising:

a processor for processing messages between a mobile telecommunications network and the fixed terminal via the wireline network, the processor being adapted to encapsulate at least a portion of an outgoing message in the mobile telecommunications network format from the fixed terminal in an appropriate wireline format so that the outgoing message from the fixed terminal is transmittable transparently through the wireline network to the mobile telecommunications network.
