Abstract

A routing system, and an associated method, for routing a call to a multi-mode transceiver. Selection of a service subscription pursuant to which calls are to be routed to the transceiver is made at the transceiver, and information related to the selected service subscription is transmitted to a service node and stored at the service node. When an originating party desires to place a call to the transceiver, the originating party accesses the information stored at the service node. Responsive to the information stored at the service node, the call is routed to the transceiver pursuant to the selected service subscription.

Claims

1. In a wireless communication system having a multi-mode transceiver operable pursuant to at least two separate service subscriptions to receive service in at least one wireless communication network, an improvement of a routing system for routing an incoming call directed to a multi-mode transceiver pursuant to a selected service subscription of the at least two separate service subscriptions, said routing system comprising:

a service selector positioned together with the multi-mode transceiver, said service selector for selecting the selected service subscription by which the incoming call directed to the multi-mode transceiver is to be routed;

a call router coupled to the at least one wireless communication network, said call router for receiving the incoming call and for routing the incoming call pursuant to the selected service subscription; and

a selected-service transmitter coupled to said service selector to receive indications of the selected service subscription selected by said service selector, said selected-service transmitter for transmitting the indications of the selected service subscription to said call router.

2. The system of claim 1 wherein said service selector further comprises a service availability determiner for determining availability of service pursuant to the at least two separate service subscriptions and wherein selection of the selected service subscription is made responsive to the availability of service pursuant to the service subscriptions.

3. The system of claim 2 wherein said service availability determiner determines the availability of service pursuant to each of the at least two separate service subscriptions.

4. The system of claim 2 wherein said service availability determiner first determines the availability of service pursuant to a preferred service subscription and wherein the preferred service subscription is selected as the selected service subscription when the preferred service subscription is determined by said service availability determiner to be available.

5. The system of claim 3 wherein said service availability determiner determines the availability of the service at timed intervals, and wherein an other-than-preferred service subscription selected as the selected service subscription continues to be the selected service subscription for at least a minimum period of time after said service availability determiner determines the preferred service subscription to be available.

6. The system of claim 4 wherein the multi-mode transceiver comprises an input element actuatable by a user of the multi-mode transceiver and wherein the preferred service subscription is selected by the user by way of actuation of the input element.

7. The system of claim 2 wherein the at least two service subscriptions comprise a cellular network service subscription and a cordless telephone service subscription and wherein the preferred service subscription is the cordless telephone service subscription.

8. The system of claim 7 wherein the cordless telephone service subscription comprises a first cordless telephone service subscription and a second cordless telephone service subscription, and wherein the preferred service subscription is the first cordless telephone service subscription.

9. The system of claim 1 wherein said service selector automatically selects the selected service subscription.

10. The system of claim 1 wherein said call router comprises a service node identified by a unique address.

11. The system of claim 10 wherein said service node forms a portion of a public telecommunications network.

12. The system of claim 10 wherein said service node forms a portion of a private telecommunications network.

13. The system of claim 10 wherein said service node comprises a physical device.

14. The system of claim 10 wherein said service node comprises a logical device.

15. The system of claim 1 wherein the indications of the selected service subscription transmitted by said selected-service transmitter comprises an information element related to a calling number identification of a selected service subscription.

16. The system of claim 1 wherein the indications of the selected service subscription transmitted by said selected-service transmitter comprises dual tone multi-frequency signals formed of sequences of tones representative of the selected service subscription.

17. The system of claim 1 wherein the indications of the selected service subscription transmitted by said selected-service transmitter is transmitted upon a control channel upon which control data is transmitted between said selected-service transceiver and said call router.

18. The system of claim 1 wherein said call router is further operative to transmit an acknowledgment signal to the multi-mode transceiver acknowledging receipt of the indications transmitted by said selected-service transmitter.

19. The system of claim 1 wherein said call router comprises at least one distributed portion and a centrally-located database portion, said at least one distributed portion coupled to said centrally-located database portion.

20. The system of claim 1 wherein said call router comprises a centrally-located service node.
