Methods and apparatus for CDMA wireless call setup time/service negotiation optimization

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.

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.

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.

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.
