Session data records and related alarming within a session over internet protocol (SOIP) network
A method and apparatus processes session layer parameters and/or extrinsic parameters with reference to an alarm condition to determine whether a route should be modified. When the alarm condition is either satisfied or unsatisfied, the route can be modified. The session layer parameters and/or extrinsic parameters are contained in a session-data-record.
1. An apparatus, comprising:
a session border controller (SBC) network controller configurable to operate within a Session over Internet Protocol (SoIP) network comprising:

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, 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; and
an alarm manager that processes the session data in the SDRs received from the SBCs with respect to an alarm condition and dynamically modifies one of a connection limit and a priority associated with a route through one or more of the SBCs when the processing indicates that an alarm-state changes.
2. The apparatus of claim 1 , wherein the alarm manager detects the alarm-state change based on an alarm condition within an alarm thread.
3. The apparatus of claim 1 , wherein the alarm manager sends an action indicator based on the alarm-state change, the action indicator triggering an action.
4. The method of claim 1 , wherein the modifying includes modifying when an alarm condition is at least one of satisfied or not satisfied with reference to the route cost indicator parameter, the alarm condition being based on the route cost indicator parameter.
5. The method of claim 1 , wherein the one of a connection limit and a priority includes a connection-limit associated with an endpoint, the endpoint being associated with the route, the modifying includes at least one of increasing the connection-limit or decreasing the connection-limit.

7. The method of claim 1 , wherein the modifying includes modifying when an alarm condition is at least one of satisfied or not satisfied with reference to the route cost indicator parameter, the alarm condition being based on the route cost indicator parameter;
the method further comprising:
sending, at the alarm manager of the session controller, an action indicator based on the alarm condition being at least one of satisfied or not satisfied, the action indicator triggering an action.
8. The method of claim 1 , wherein the modifying includes modifying when an alarm condition is at least one of satisfied or not satisfied with reference to the route cost indicator parameter, the alarm condition being based on the route cost indicator parameter, 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.
9. A method, comprising:
receiving, at a session detail record (SDR) receptor manager of a session border controller (SBC) network controller within a Session over Internet Protocol (SoIP) network, session data of a media session comprising 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, 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; and
modifying, at an alarm manager of the SBC network controller, one of a connection limit and a priority associated with the route when an alarm-state of an alarm condition is changed from at least one of satisfied to unsatisfied and unsatisfied to satisfied, the alarm condition being based on a combination of the session layer parameter and the extrinsic parameter.
10. The method of claim 9 , wherein the session layer parameter and the extrinsic parameter are associated with at least one session controller, the one of a connection limit and a priority being associated with the at least one session controller.
11. The method of claim 9 , wherein the one of a connection limit and a priority includes a connection-limit associated with an endpoint, the endpoint being within the SoIP network, the modifying includes at least one of increasing the connection-limit or decreasing the connection-limit.
12. The method of claim 9 , wherein the one of a connection limit and a priority includes a priority associated with at least one of the route and an endpoint, the at least one of the route and the endpoint being associated with the SoIP network, the modifying including modifying the priority.
13. The method of claim 9 , 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.
14. The method of claim 9 , wherein the session layer parameter includes at least one of a low media quality, a high packet loss, and a packet delay variance.
15. The method of claim 9 , wherein the extrinsic parameter includes at least one of a time-of-day, a day-of-a-week, a system load filter, and a route cost indicator parameter.
16. A method, comprising:
measuring, at a session border controller (SBC), a quality-of-service (QoS) value for a Session over Internet Protocol (SoIP) connection between a source endpoint, the SBC, and a destination endpoint, the measuring being based on information for a portion of the SoIP connection, the portion of the SoIP connection being a transmission from at least one of the source endpoint and the destination endpoint to the SBC;
the QoS value included in a session detail record (SDR) associated with the SoIP connection, the SDR including session data of a media session comprising 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, and a ratings factor (r-factor),
