Abstract

Methods and systems for routing information to a destination through a plurality of networks, wherein at least one of the networks is a packet network. The system comprises a routing processor for receiving a routing query signal, which specifies the destination to which the information will be routed and a memory for storing at least one characteristic of the destination. The processor determines a route for the transmission of the information based on the routing query and on the characteristics stored in the memory.

Claims

1. A system for managing the routing of information from a source to a destination through a plurality of networks, wherein at least one of the networks is a packet network, the system comprising:

a routing processor for receiving a query signal from the source via a wireless link, wherein the query signal specifies the destination to which the information will be routed, and wherein the processor is configured to identify a subscriber service associated with the destination;

at least one subsystem that stores;

one or more characteristics of the source;

one or more characteristics of the destination, said one or more characteristics of the destination including the type of equipment at the destination, and information indicating a type of service associated with the destination wherein the type of service is one of a fixed wireless service or a PSTN service; and

information about the topology of the networks;

at least one subsystem, accessible from the routing processor, that determines a route for the transmission of the information based on;

the query signal,

the identified subscriber service associated with the destination,

the characteristics stored in the memory, and

the information about the topology of the networks; and

at least one subsystem, other than the source, that converts the information sent over the route into data packets.

2. The system according to claim 1, wherein the source subscribes to a fixed wireless service network.

3. The system according to claim 2, wherein the destination subscribes to the same fixed wireless service network as the source.

4. The system according to claim 2, wherein the destination subscribes to a PSTN service network.

5. The system according to claim 1, wherein the information includes digitized voice information.

6. The system according to claim 1, wherein the signal is a DTMF signal.

7. A method for managing the routing of information to a destination through a plurality of networks, wherein at least one of the networks is a packet network, and wherein each network is linked to at least one other network by a communication medium, the method comprising:

receiving a query specifying a destination to which the information will be routed at a routing processor, wherein the destination is one of at least two possible destinations, and wherein the type of equipment at the destination is one of a fixed wireless subscriber device or a PSTN subscriber device

storing one or more characteristics of the destination, including information indicating whether the equipment at the destination is fixed wireless subscriber device or a PSTN subscriber device;

storing information about the network topology;

identifying a subscriber service associated with the destination; and

if the destination subscribes to a service associated with a wired information transfer network, determining a route for the transmission of the information based on

the query

the one or more stored characteristics, and

converting the information sent over the route into data packets.

8. The method according to claim 7, wherein the storing the one or more characteristics includes storing at least one address for the destination.

9. A method for managing the routing of information to a destination through a plurality of networks, wherein at least one of the networks is an ATM packet network, and wherein each network is linked to at least one other network by a communication medium, the method comprising:

receiving a query specifying a destination to which the information will be routed at a routing processor, wherein the destination is one of at least two possible destinations, and wherein at least three different types of equipment are each associated with a possible destination;

storing one or more characteristics of the destination;

storing information about the ATM packet network topology;

identifying a subscriber service associated with the destination, wherein said subscriber service is one of a fixed wireless service or a PSTN service; and

determining a transmission path for routing the information through the networks, wherein the determining is based at least in part on;

the received query signal, the stored ATM packet network topology information the stored characteristics, wherein the stored characteristics include information indicating the type of equipment at the destination, and the identified subscriber service associated with the destination.

10. The method according to claim 9 wherein the equipment at the destination comprises a facsimile device.

11. The method according to claim 9 wherein the equipment at the destination comprises a computer.

12. The method according to claim 9 wherein the equipment at the destination comprises a modem.

13. The method according to claim 9 wherein, if the destination subscribes to a service associated with a wired information transfer network and the equipment at the destination is configured to accept information from the source via the wired information transfer network alone, and wherein the determined transmission path does not comprise an ATM packet network in addition to the wired information transfer network.

14. The method according to claim 9 wherein, if the destination subscribes to a service associated with a wireless information transfer network, the determined transmission path comprises at least one ATM packet network.

15. A system for managing the routing of information from a source to a destination through a plurality of networks, wherein at least one of the networks is an ATM packet network, the system comprising:

a routing processor for receiving a query signal from the source, the signal specifying the destination to which the information will be routed, the destination being one of at least two possible destinations, wherein at least two different types of equipment are each associated with a possible destination;

at least one subsystem that identifies a subscriber service associated with the destination;

at least one subsystem that stores one or more characteristics of the destination wherein the stored characteristics include information indicating the type of equipment at the destination;

at least one subsystem that identifies the subscriber service associated with the destination;

at least one subsystem that stores information about the ATM packet network topology; and

at least one subsystem that determines a transmission path for routing the information through the networks based at least in part on the received query signal, the stored ATM packet network topology information, the stored characteristics, and the identified subscriber service associated with the destination.

16. The system according to claim 15, wherein the source subscribes to a fixed wireless service network.

17. The system according to claim 16, wherein the destination subscribes to the same fixed wireless service network as the source and wherein the system further comprises at least one subsystem that converts the information sent over the transmission path into data packets.

18. The system according to claim 16, wherein the destination subscribes to a PSTN service network.

19. The system according to claim 15, wherein the information includes digitized voice information.

20. The system according to claim 15, wherein the signal is a DTMF signal.

21. A method for managing the routing of information to a destination through a plurality of networks, wherein at least one of the networks is an ATM packet network, and wherein each network is linked to at least one other network by a communication medium, the method comprising:

receiving a query specifying a destination to which the information will be routed at a routing processor, wherein the destination is one of at least three possible destinations, and wherein at least two different types of equipment are each associated with a possible destination;

storing information about the ATM packet network topology;

identifying a subscriber service associated with the destination;

determining a route for transmission of the information based on the query, the type of equipment at the destination, the network topology and the subscriber service associated with the destination; and
