Method and apparatus for a hybrid mobile terminal
View Patent ↗An access network controller and a base station controller are formed to define an interface there between that enables the two systems to facilitate and respond to a voice call that is to be set up to a hybrid mobile station even though the hybrid mobile station is presently engaged in a data only call. More specifically, the base station is formed to generate a pseudo-page signal to the access network controller to determine whether the hybrid mobile station is present and available prior to the base station generating paging signals to establish the voice call. According to the response received from the access network controller, the base station either pages the hybrid mobile station to establish the voice call, forwards the call to voice mail, or forwards the call either to an Internet Call Delivery Server or to an Internet Call-Waiting Server.
1. An access network controller, comprising:
a processor;
communication circuitry within the access network controller;
a memory for storing computer instructions that define profile information for at least one hybrid mobile station (HMS) and that define operational logic relating to a response of the access network controller to a received pseudo-page signal and that define profile information that specify that the access network controller is to generate a response to a base station to advise it that the HMS has been paged and is being redirected to receive pages from the voice network; and
a network port for enabling the access network controller to communicate with external systems.
2. The access network controller of claim 1 wherein the computer instructions that define the profile information specify that the access network controller is to generate a response to a base station to advise it that the HMS is unavailable.
3. The access network controller of claim 1 wherein the computer instructions that define the profile information specify that the access network controller is to generate a response to a base station to advise it that the HMS is present but not available for a voice call.
4. The access network controller of claim 1 wherein the memory further includes computer instructions that define an operational logic for forwarding a voice call to an Internet Call Delivery Server.
5. The access network controller of claim 1 wherein the memory further includes computer instructions that define operational logic for forwarding a voice call to an Internet Call-Waiting Server.
6. A method in a communication network including a voice network and a data network, comprising:
receiving a pseudo-page signal transmitted by a base station in a specified interface signal between the base station and an access network controller;
generating, from the access network controller, a response to the base station to advise it that a hybrid mobile station has been paged and is being redirected to receive pages from the voice network, wherein the response includes waiting long enough to enable the hybrid mobile station to switch from the data network to the voice network and then advising the base station that the hybrid mobile station is at least one of being presently available and not being presently available; and
commanding the hybrid mobile station to redirect and to suspend a data call so that it may receive and respond to paging signals transmitted by the base station.
7. The method of claim 6 wherein the response includes forwarding the voice call to an Internet Call-Waiting Server.
8. The method of claim 6 wherein the response further includes advising the base station whether the hybrid mobile station is present but not available.
9. The method of claim 6 wherein the response includes advising the base station whether the hybrid mobile station is present and available.
10. An access network controller, comprising:
a processor;
communication circuitry within the access network controller;
a memory for storing computer instructions that define profile information for at least one hybrid mobile station (HMS) and that define operational logic relating to a response of the access network controller to a received pseudo-page and that define operational logic for forwarding a voice call to one of an Internet Call Delivery Server or to an Internet Call-Waiting Server; and
a network port for enabling the access network controller to communicate with external systems.
11. The access network controller of claim 10 wherein the computer instructions that define the operational logic relating to a response of the access network controller to a pseudo-page is to further respond that the HMS is unavailable.
12. The access network controller of claim 11 wherein the computer instructions that define the operational logic relating to a response of the access network controller to a pseudo-page is to further respond that the HMS is present but not available for a voice call.
