Abstract

A system, method, and computer readable medium for managing an availability of a call agent, comprising acquiring a session identification by a basestation (BS) and a call agent (CA), wherein the BS is coupled to the CA, if the CA's state is changed from an active state to a standby state, requesting a new connection with the BS; and after the new connection is established between the CA and the BS, sending another session identification from the CA to the BS.

Claims (40)

1. A method, comprising:

acquiring a session identification by a basestation (BS) and a call agent (CA), wherein the BS is coupled to the CA;

establishing a new connection between the CA and the BS;

sending another session identification from the CA to the BS;

wherein the session identification includes a local session identification and a remote session identification;

wherein the local session identification and the remote session identification are shared between an active processor and a standby processor in the CA; and

starting a timer upon failure of a transport layer;

wherein if the timer expires, changing the local session identification is the BS has already released an existing call.

2. The method of claim 1 , wherein the session identification message is the same as the other session identification message.

3. The method of claim 2 comprising continuing to process an existing call by the BS when the other session identification message is received.

4. The method of claim 1 , wherein the new connection is established between a redundant CA and the BS.

5. The method of claim 1 , wherein the local session identification and the remote session identification are shared between an active processor in the BS.

6. The method of claim 1 , wherein the local session identification and the remote session identification are shared between a standby processor in the BS.

7. The method of claim 1 , wherein the session identification is stored in a session initiation message sent between the BS and the CA.

8. The method of claim 1 , wherein the session identification is used to check a status between the BS and the CA.

9. The method of claim 1 , wherein the session identification is acquired to guarantee a return of a different session identification on a sequential restart.

10. The method of claim 9 , wherein the different session identification alerts the BS or the CA that a new call is to be processed.

11. The method of claim 9 , wherein utilizing a just used session identification would allow the BS or the CA to continue processing a previous call.

12. The method of claim 1 , wherein until the session identification is issued, the BS should not send any application messages.

13. The method of claim 1 , wherein until the session identification is issued, the CA should not send any application messages.

14. The system of claim 13 , wherein a timer is started upon failure of a transport layer; and wherein if the timer expires, the local session identification is changed if the BS has already released an existing call.

15. The method of claim 7 , wherein the session initiation message includes at least one of: a length, a message type, and a local session identification.

16. A system, comprising:

a first module; and

a second module, wherein the first module is coupled to the second module;

wherein the first module and the second module acquire a first identification;

wherein a new connection is established between the second module and the first module;

wherein a second session identification is sent from the second module to the first module;

wherein the second session identification is equivalent to the first session identification;

wherein the session identifications include a local session identification and a remote session identification;

wherein the timer is started upon failure of a transport layer;

wherein if the timer expires, the first session identification is changed if the first module has already released an existing call.

17. A non-transitory computer readable medium comprising instructions for:

acquiring a session identification by a basestation (BS) and a call agent (CA), wherein the BS is coupled to the CA;

establishing a new connection between the CA and the BS;

sending another session identification from the CA to the BS;

wherein the session identification includes a local session identification and a remote session identification;

wherein the local session identification and the remote session identification are shared between an active processor and a standby processor in the CA; and

starting a timer upon failure of a transport layer;

wherein if the timer expires, changing the local session identification if the BS has already released an existing call.
