State machine for use in call processing system and method of operation

A wireless network comprising:

• a plurality of base stations capable of communicating with a plurality of mobile stations located in a coverage area of said wireless network, each of said plurality of base stations comprising:
• a plurality of RF transceivers, each of said RF transceiver capable of transmitting at least one of voice signals and data signals in a forward channel to a selected one of said plurality of mobile stations and capable of receiving at least one of voice signals and data signals in a reverse channel from said selected mobile station;
• and
• a call control processor capable of controlling said plurality of RF transceivers, said call control processor comprising a first state machine capable of performing a call processing task in response to receipt of a message retrieved from an operating system queue associated with said first state machine, said first state machine comprising an internal queue capable of storing a plurality of events associated with said call processing task, each of said plurality of events operable to cause said first state machine to perform a selected action, wherein said first state machine is capable of communicating with a second state machine of said call control processor by storing at least one event directly into an internal queue associated with said second state machine.

For use in a base station in a wireless network, a method of operating a call control processor comprising the steps of:

• retrieving from an operating systems queue associated with a first state machine of the call control processor a message capable of causing the first state machine to perform a call processing task;
• retrieving from an internal queue associated with the first state machine of the call control processor a stored event capable of causing the first state machine to perform an action;
• generating from the stored event at least one resultant event;
• determining if a second state machine of the call control processor utilizes the at least one resultant event;
• translating the at least one resultant event into a corresponding event associated with the second state machine;
• and
• storing the corresponding event directly into an internal queue associated with the second state machine by the first state machine for subsequent execution by the second state machine.
