Policy coordination between policy enforcement points

摘要

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.

1. 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; andchange 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.
