Abstract

An apparatus in one example has: at least a first network of a first predetermined type and at least a second network of a predetermined type; at least one mobile terminal movable between the first and second networks; at least one gateway operatively coupled to each of the first and second networks; and at least one message that communicates via the gateway at least feature data of the mobile terminal from one of the first and second networks to the other of the first and second networks.

Claims

1. An apparatus, comprising:

at least a first network of a first predetermined type and at least a second network of a predetermined type;

at least one mobile terminal movable between the first and second networks;

at least one gateway operatively coupled to each of the first and second networks; and

at least one message that communicates via the gateway at least feature data of the mobile terminal from one of the first and second networks to the other of the first and second networks;

wherein the mobile terminal and a feature application server use a predetermined format for supplementary service encoding, and wherein the mobile terminal is operable to make at least one supplementary service request to activate call forwarding service via the message.

2. The apparatus according to claim 1, wherein one of the first and second networks in an IP Multimedia Subsystem (IMS) network, and wherein the IMS network has the feature application server.

3. The apparatus according to claim 1 wherein the mobile terminal is one of a cellular phone and an IP Multimedia Subsystem (IMS)-capable device.

4. The apparatus according to claim 1, wherein the mobile terminal is part of a user equipment configuration having a plurality of distinct user equipment types, and wherein at least one of the distinct user equipment types is one of IP Multimedia Subsystem (IMS)-compatible or have a mode of operation that is IMS-compatible.

5. The apparatus according to claim 1, wherein the first network is a cellular-based network, and wherein the second network is an IP Multimedia Subsystem (IMS) network.

6. The apparatus according to claim 5, wherein the gateway is part of the IMS network.

7. The apparatus according to claim 1, wherein the message is a Short Message Service (SMS) message.

8. The apparatus according to claim 1, wherein the mobile terminal has a message module that originates a Short Message Service (SMS) message and wherein the gateway has an interface module that forwards the SMS message.

9. The apparatus according to claim 8, wherein the first network is a cellular-based network that has a mobile switching center, and wherein the second network is an IP Multimedia Subsystem (IMS) network that has the feature application server and an SMS translation module.

10. A method, comprising the steps of:

capturing supplementary service requests that are made while a mobile terminal is in one of a cellular-based network and an IP Multimedia Subsystem (IMS) network; and

communicating the supplementary service request between the cellular-based network and the IMS network such that each of the cellular-based network and the IMS network have current features associated with the mobile terminal when the mobile terminal is within a respective coverage area of the cellular-based network and the IMS network;

employing the mobile terminal to make at least one supplementary service request to activate call forwarding service;

wherein, when the mobile terminal is in the cellular-based network, the mobile terminal encapsulates the supplementary service request into a mobile-originated SMS message having a predetermined format with a destination number of a feature application server in the IMS network.

11. The method according to claim 10, wherein the feature application server in the IMS network unpacks the SMS message and updates its subscriber data with new supplementary service information, and wherein the mobile terminal and the feature application server use a predetermined format for supplementary service encoding.

12. The method according to claim 10 wherein the mobile terminal is a cellular phone.

13. The method according to claim 10 wherein the mobile terminal is an IMS-capable device.
