Abstract

Techniques to forward unsolicited messages from an (IS-2000) CDMA radio network via an HDR radio network to an access terminal. A session is first established between the access terminal and the HDR radio network. During session establishment or thereafter, the access terminal indicates to the HDR radio network an interest in receiving unsolicited messages from the CDMA radio network. The access terminal typically also registers with the CDMA radio network. Thereafter, unsolicited messages can be sent from a mobile station controller (MSC) to the HDR and CDMA radio networks, or sent from the MSC to the CDMA radio network, which then forwards the messages to the HDR radio network. The HDR radio network encapsulates the unsolicited messages and sends the encapsulated messages to the access terminal. The forwarding of unsolicited messages allows the CDMA radio network to communicate with an access terminal.

Claims

1. A method for communicating with first and second radio networks, the method comprising:

establishing a first communication session with the first radio network;

selectively authorizing the first radio network to forward unsolicited messages for a first service option from the second radio network and not forward unsolicited messages for a second service option, wherein the authorizing comprises periodically sending requests to the first radio network for receiving unsolicited messages from the second radio network; and

sending a registration message to the second radio network by a transmitter.

2. The method as in claim 1 further including sending a request to the first radio network for terminating receiving the unsolicited messages from the second radio network.

3. An access terminal for communicating with first and second radio networks, comprising:

means for establishing a first communication session with the first radio network;

means for selectively authorizing the first radio network to forward unsolicited messages for a first service option from the second radio network and not forward unsolicited messages for a second service option, wherein the means for selectively authorizing comprises means for periodically sending requests to the first radio network for receiving unsolicited messages from the second radio network; and

means for sending a registration message to the second radio network.

4. The access terminal as in claim 3 further including means for sending a request to the first radio network for terminating receiving the unsolicited messages from the second radio network.

5. An access terminal for communicating with first and second radio networks, comprising:

a processor; and

circuitry coupled to the processor cooperatively configured to establish a first communication session with the first ratio network, selectively authorize the first radio network to forward unsolicited messages for a first service option from the second radio network and not forward unsolicited messages for a second service option, and send a registration message to the second radio network;

wherein the circuitry configured to selectively authorize comprises circuitry configured to periodically send requests to the first radio network for receiving unsolicited messages from the second radio network.

6. The access terminal as in claim 5 wherein the processor and the circuitry being further configured to send a request to the first radio network for terminating receiving the unsolicited messages from the second radio network.

7. A communication entity comprising:

a controller; and

an access point coupled to the controller cooperatively configured to establish a communication session with an access terminal, periodically receive requests from the access terminal that selectively authorize the access point to forward unsolicited messages for a first service option from a radio network and not forward unsolicited messages for a second service option, and send the unsolicited messages for the first service option to the access terminal.

8. A computer program product for communicating with first and second radio networks, comprising:

a non-transitory computer-readable medium embodying computer instruction codes which when excuted by a computer to achieve functions, compprising;

establishing a first communication session with the first radio network;

selectively authorizing the first radio network to forward unsolicited messages for a first service option from the second radio network and not forward unsolicited messages for a second service option, wherein the authorizing comprises periodically sending requests to the first radio network for receiving unsolicited messages from the second radio network; and

sending a registration message to the second radio network by a transmitter.

9. The computer program product as in claim 8 further including a function of sending a request to the first radio network for terminating receiving the unsolicited messages from the second radio network.
