Abstract

A method includes receiving an instruction associated with a definition of an alarm condition and modifying a session controller associated with a Session over Internet Protocol (SoIP) network based on the alarm condition. The session controller can be modified when the alarm condition, which is defined based on session data, is changed from satisfied to unsatisfied or unsatisfied to satisfied. The modifying of the session controller is associated with a set of connections that includes more than zero connections.

the SBC sending the SDR to the alarm manager of the SBC network controller, and

the SBC selecting a different intermediate destination endpoint from the plurality of intermediate destination endpoints with which to route the media session, such that the modified route bypasses the original intermediate destination endpoint in reaching the destination terminal adapter.

2.

3. The method of claim 1, wherein the modifying the route when the alarm-state is changed from unsatisfied to satisfied includes modifying route information for the route based on an indicator triggered in response to the alarm-state being changed from unsatisfied to satisfied, the route information being associated with at least one session controller.

4. The method of claim 1, wherein the modifying the route when the alarm-state is changed from satisfied to unsatisfied includes modifying route information for the route based on an indicator triggered in response to the alarm-state being changed from satisfied to unsatisfied, the route information being associated with at least one session controller.

5. The method of claim 1, wherein the modifying the route when the state of the alarm is changed from unsatisfied to satisfied includes modifying a priority associated with the route, the modifying the route when the state of the alarm is changed from satisfied to unsatisfied includes modifying the priority associated with the route.

6. The method of claim 1, wherein:

the alarm-state changes from unsatisfied to satisfied when the alarm condition is satisfied based on the session data,

the alarm-state changes from satisfied to unsatisfied when the alarm condition is unsatisfied based on the session data.

7. The method of claim 1, wherein the alarm condition is included in a first alarm thread from a plurality of alarm threads, the plurality of alarm threads being executed in parallel.

8. A method, comprising:

at a session border controller (SBC);

receiving an instruction associated with a definition of an alarm condition; and

modifying a connection-limit associated with an endpoint when an alarm-state of the alarm condition is changed from at least one of unsatisfied to satisfied and satisfied to unsatisfied, the endpoint being within a Session over Internet Protocol (SoIP) network, an indicator of the alarm condition received from an alarm manager of an SBC network controller and based on session data about the media session stored within a session detail record (SDR);

wherein modifying the connection-limit associated with the endpoint includes the SBC generating the SDR which contains the session data about the media session, the session data including session layer parameters and extrinsic parameters,

wherein the session layer parameters include at least one of a call duration indicator, a start time indicator, an end time indicator, a source endpoint indicator, a destination endpoint indicator, a delay indicator, a media quality indicator, a packet loss indicator, a packet delay variance indicator, a quality of service parameter, and a ratings factor (r-factor),

wherein the extrinsic parameters include at least one of a time-of-day indicator, a day-of-week indicator, a number-of-calls indicator, and a route cost indicator parameter,

the SBC sending the SDR to the alarm manager of the SBC network controller, and

the SBC modifying the connection-limit associated with the endpoint, the modified connection-limit being greater than zero.

9. The method of claim 8, wherein the modifying includes at least one of increasing the connection-limit on at least one session controller and decreasing the connection-limit on at least one session controller.

10. The method of claim 8, wherein the alarm condition includes a first condition and a second condition, the alarm-state is changed from unsatisfied to satisfied based on the first condition within the alarm condition, the alarm-state is changed from satisfied to unsatisfied based on the second condition within the alarm condition.

11. The method of claim 8, wherein the alarm condition is included in a first alarm thread from a plurality of alarm threads, the plurality of alarm threads being executed in parallel.

12. The method of claim 8, wherein:

the alarm-state changes from unsatisfied to satisfied when the alarm condition is satisfied based on the session data,

the alarm-state changes from satisfied to unsatisfied when the alarm condition is unsatisfied based on the session data.

13. A method, comprising:

at a session border controller (SBC);
