Abstract
According to an example, a unified policy management system may include a session manager module to establish sessions with policy enforcement points. A notification manager module may receive an event trigger notification from a policy enforcement point via an interface session. A coordination engine may determine whether an event identified from the event trigger notification is to cause a change in policy enforced by another policy enforcement point and facilitate the change via another interface session.
Claims15
A Unified Policy Management (UPM) system comprising:
- at least one processor;
- and
- a non-transitory computer readable medium storing instructions that when executed by the at least one processor cause the at least one processor to:
- establish interface sessions with a plurality of policy enforcement points (PEPs), wherein the interface sessions are for a same subscriber;
- receive an event trigger notification from a first PEP of the plurality of PEPs via a first interface session of the interface sessions;
- determine whether an event identified from the event trigger notification is associated with a policy enforced by a second PEP of the plurality of PEPs;
- in response to a determination that the event identified from the event trigger notification is associated with a policy enforced by the second PEP, determine whether the policy enforced by the second PEP is to be changed;
- and
- change the policy to be enforced by the second PEP in response to a determination that the policy enforced by the second PEP is to be changed, by sending a message to the second PEP via a second interface session of the interface sessions to change the policy in the second PEP.
A non-transitory computer readable medium storing machine readable instructions executable by at least one processor to:
- establish interface sessions between a Unified Policy Management (UPM) system and a plurality of policy enforcement points (PEPs) that enforce policies;
- receive an event trigger notification from a first PEP of the plurality of PEPs via a first interface session of the interface sessions;
- determine whether an event identified from the event trigger notification is associated with a policy enforced by a second PEP of the plurality of PEPs;
- in response to a determination that the event identified from the event trigger notification is associated with a policy enforced by the second PEP, determine whether the policy enforced by the second PEP is to be changed;
- and
- change the policy to be enforced by the second PEP in response to a determination that the policy enforced by the second PEP is to be changed, by sending a message to the second PEP via a second interface session of the interface sessions to change the policy in the second PEP, wherein the first and second interface sessions are for a same subscriber.
A method comprising:
- establishing sessions between a Unified Policy Management (UPM) system and first and second policy enforcement points (PEPS) via first and second interface sessions, respectively;
- receiving, by the UPM system, an event trigger notification from the first PEP via the first interface session;
- determining, by at least one processor of the UPM system, whether an event identified from the event trigger notification is associated with a policy enforced by the second PEP;
- determining whether the policy enforced by the second PEP is to be changed;
- and
- changing the policy to be enforced by the second PEP in response to a determination that the policy enforced by the second PEP is to be changed, by sending a message from the UPM system to the second PEP via the second interface session to change the policy in the second PEP.
