Method and system for communicating between a media processor and network processor in a gateway device
View Patent ↗A gateway device includes a media processor module comprising a gateway application module. The gateway device also includes a router module comprising a gateway abstraction module and an interface handler module. The gateway device also includes a shared interface module in communication with the router module and the media processor module. The shared interface module receives a service request signal from the gateway application module. The gateway abstraction module obtains the service request signal from the shared interface module through an interface handler module. The gateway abstraction module communicates a response signal to the media processor module through the shared interface module. The media processor module performs a function in response to the response signal.
1. A method of operating a gateway device having a router module, a media processor module and a shared memory intercommunicating with the router module and the media processor module, said method comprising:
receiving a request signal at the shared memory from a gateway application module of the media processor module;
obtaining, at the router module, the request signal from the shared memory through an interface of the router module;
communicating the request signal to a first module within the router module;
communicating a response signal representing a function from the first module to the media processor module through the shared memory; and
performing the function at the media processor module in response to the response signal.
2. The method as recited in claim 1 further comprising validating the request signal at a validation module of the router module.
3. The method as recited in claim 1 further comprising serializing the request signal at a first serializer/deserializer module of the media processor module to form a serialized request signal, and deserializing the serialized request signal at a second serializer/deserializer module of the router module.
4. The method as recited in claim 3 wherein obtaining the request signal from the shared memory comprises obtaining the serialized request signal through a communication channel.
5. The method as recited in claim 1 further comprising the step of bypassing an IP protocol stack at the gateway device.
6. The method as recited in claim 1 further comprising bypassing an IP protocol stack during communicating the request and communicating the response.
7. The method as recited in claim 1 wherein receiving the request signal comprises receiving an originator identifier.
8. The method as recited in claim 1 wherein receiving the request signal comprises receiving a timestamp.
9. The method as recited in claim 1 wherein receiving the request signal comprises receiving a quality of service flow signal.
10. The method as recited in claim 1 wherein performing the function comprises generating a screen display.
11. A gateway device comprising:
a media processor module;
a router module comprising an interface; and
a shared memory in communication with the router module and the media processor module, said shared memory receiving a request signal from the media processor module;
said media processor module obtaining the request signal from the shared memory through the interface;
said router module communicating a response signal to the media processor module through the shared memory; and
said media processor module performing a function in response to the response signal.
12. The gateway as recited in claim 11 wherein the router module comprises a validation module validating the request signal.
13. The gateway as recited in claim 11 wherein the media processor module comprises a first serializer/deserializer module serializing the request signal to form a serialized request signal and wherein the router module comprises a second serializer/deserializer module deserializing the serialized request signal.
14. The gateway as recited in claim 13 wherein the router module obtains the request signal from the shared memory through a communication channel.
15. The gateway as recited in claim 11 wherein the request signal comprises an originator identifier.
16. The gateway as recited in claim 11 wherein the request signal comprises a timestamp.
17. The gateway as recited in claim 11 further comprising an IP protocol stack, said media processor and the router module bypassing the IP protocol stack during communications therebetween.
18. The gateway as recited in claim 13 wherein the request signal comprises a quality of service flow signal.
19. The gateway as recited in claim 11 wherein the request signal comprises a session creation or session deletion signal.
20. The gateway as recited in claim 11 wherein the function comprises generating a screen display.
