Abstract

One aspect of the invention is a method for wireless call processing. The method includes downloading at least one function-specific logic control program into each of a plurality of generic logic control state machines and receiving a message at a wireless protocol-specific codec, parsing the message, and routing the message to a first logic control state machine associated with the protocol-specific codec. The method also includes executing the function-specific logic control program of a first logic control state machine and generating a call event and routing the call event to an event codec. The method also includes executing the function-specific logic control program of a second logic control state machine and processing the call event. In a particular embodiment, the method also includes allocating an RF channel that may be used for the call event without seizing the RF channel. In another embodiment, the method also includes accessing a database that includes routing and verification information related to the call event, and routing the call event in response to the information.

Claims

1. A protocol-independent system for processing a wireless call event, comprising:

at least one control agent having

a first generic logic control state machine operable to execute a first logic control program to process a signaling message;

a first signaling codec specialized in a particular wireless signaling protocol and operable to parse and format the signaling messages; and

a first filter operable to filter and route the signaling messages from the codec to the first logic control state machine;

at least one mobility management agent having

a second generic logic control state machine operable to execute a second logic control program to process a control protocol message;

a second codec specialized in a particular wireless control protocol and operable to parse and format the control protocol messages; and

a second filter operable to filter and route the control protocol messages from the codec to the second logic control state machine; and

at least one intelligence control agent having

a third generic logic control state machine operable to execute a third logic control program to process call events received from the mobility management agent and the control agent; and

access to a database, the database including routing and verification information related to the call event.

2. The system, as set forth in claim 1, wherein the intelligence control agent is operable to parse and route one of the group selected from AMPS signaling messages, CDMA signaling messages, GSM signaling messages, and TDMA signaling messages.

3. The system, as set forth in claim 1, wherein the second codec is operable to interface with one of the group selected from a GSM base station, a W-CDMA radio gateway, a W-TDMA radio gateway, a GPRS radio gateway, and a GSM receiver, a CDMA receiver, a TDMA receiver, and an AMPS receiver.

4. The system, as set forth in claim 1, wherein the intelligence control agent is further operable to access a database that includes routing and verification information related to the call event and to route the call event in response to the information.

5. The system, as set forth in claim 4, wherein the mobility management agent is further operable to route the call event using voice over IP.

6. The system, as set forth in claim 1, wherein the control agent further includes another codec operable to parse and route one of the group selected from H.323 signaling messages and SS7 signaling messages.

7. The system, as set forth in claim 1, wherein the second codec is operable to allocate an RF channel that may be used for the call event without seizing the RF channel.
