Abstract

Methods and apparatus for initiating calls between a mobile station and a base station in a wireless CDMA system wherein status request messages and status response messages are not required for the base station to determine alternate service options supported by the mobile stations are disclosed in accordance with the teachings of the present invention. The invention includes the mobile station transmitting an origination message to the base station wherein the origination message includes all service options supported by the mobile station. The invention also includes the situation where the base station sends a page message to the mobile station. The mobile station responds by determining whether the page message is intended therefor. If it is and if the mobile station is configured to receive mobile station terminated calls, the mobile station transmits a page response message to the base station which includes the service options supported by the mobile station.

Claims

1. In a wireless communication system, a method of initiating calls between a mobile station and a base station wherein status request messages and status response messages are not required for the base station to determine alternate service options supported by the mobile station comprising:

said mobile station generating an origination message including;

a field including a preferred service option supported by said mobile station; and

,

another field including at least one service option supported by said mobile station; and

,

said mobile station transmitting said origination message to said base station.

2. The method of initiating calls according to claim 1 wherein said origination message further includes a field including a number representing said at least one service option.

3. The method of initiating calls according to claim 1 wherein said at least one service option does not include said preferred service option.

4. The method of initiating calls according to claim 1 wherein said at least one service option includes said preferred service option.

7. The method of initiating calls according to claim 4 wherein said another field includes said preferred service option.

8. The method of initiating calls according to claim 4 wherein said another field does not include said preferred service option.

5. In a wireless communication system, a method of initiating calls between a mobile station and a base station wherein status request messages and status response messages are not required for the base station to determine alternative service options supported by the mobile station comprising:

said base station sending a page message to said mobile station;

said mobile station determining whether said page message is intended for said mobile station;

said mobile station transmitting a page response message to said base station if said mobile station determines that said page message is intended for said mobile station and if said mobile station is configured to receive mobile station terminated calls;

wherein said page response message includes;

a field for a preferred service option supported by said mobile station; and

,

another field for at least one service option supported by said mobile station.

6. The method of initiating calls according to claim 5 wherein said page response message further includes a field including a number representing said at least one service option.

9. A wireless communication system configured to initiate calls between a mobile station and a base station wherein status request messages and status response messages are not required for the base station to determine alternative service options supported by the mobile station comprising:

means for generating an origination message including;

a field including a preferred service option; and

,

another field including at least one service option supported by said mobile station; and

,

at least one transmitter for transmitting an origination message generated by said message generating means.

10. The system of initiating calls according to claim 9 wherein said at least one service option includes said preferred service option.

11. The system of initiating calls according to claim 9 wherein said at least one service option does not include said preferred service option.

12. A wireless communication system configured to initiate calls between a mobile station and a base station wherein status request messages and status response messages are not required for the base station to determine alternative service options supported by the mobile station comprising:

means associated with said base station for generating a page message;

a transmitter associated with said base station, coupled to said page message generating means and configured to transmit said page message;

a receiver associated with said mobile station and configured to receive said page message;

means for determining if said page message is intended for said mobile station;

means for generating a page response message;

said page response generating means configured to generate said page response message only if said determining means determines that said page message is intended for said mobile station;

wherein said page response message includes;

a field including a preferred service option; and

,

another field including at least one service option supported by said mobile station; and

,

a transmitter coupled to said page response generating means and configured to transmit said page response message.

13. The system of initiating calls according to claim 12 wherein said at least one service option includes said preferred service option.

14. The system of initiating calls according to claim 12 wherein said at least one service option does not include said preferred service option.

15. A wireless communication system configured to initiate calls between a mobile station and a base station wherein status request messages and status response messages are not required for the base station to determine alternative service options supported by the mobile station comprising:

a microprocessor associated with said base station and configured to generate a page message;

a transmitter associated with said base station, coupled to said microprocessor and configured to transmit said page message;

a receiver associated with said mobile station and configured to receive said page message;

a microprocessor associated with said mobile station, coupled to said receiver and configured to determine if said page message is intended for said mobile station;

said microprocessor further configured to generate a page response message if it determines that said page message is intended for said base station;

wherein said page response message includes;

a field including a preferred service option; and

,

another field including at least one service option supported by said mobile station; and

,

a transmitter associated with said mobile station, coupled to said microprocessor and configured to transmit said page response message.

16. The system of initiating calls according to claim 15 wherein said at least one service option includes said preferred service option.

17. The system of initiating calls according to claim 15 wherein said at least one service option does not include said preferred service option.
