Enhanced media control

摘要

An enhanced mechanism for conflict resolution between authorized services in respect of selective authorization criteria, such as service incompatibilities, subscribed bandwidth QoS assigned per subscriber and pre-emption priority value assigned per service. The present invention allows the authorization of a subsequent service as a result of applying a selective authorization criterion for the subscriber at a policy control rules server to determine those previously authorized services to be put on hold, notifying about said previously authorized services to be on hold towards application devices handling such services, and inactivating at a policy enforcement device those control rules applicable to the media associated with said previously authorized services. In addition, the method as well as the policy control rules server, the application devices and the policy enforcement device may be also arranged for re-activating said previously authorized services still on hold when the reason for being on hold has ceased.

主权项

1. A policy control rules server for generating control rules based on service information received from application devices and for installing said control rules in a policy enforcement device responsible for guaranteeing a bandwidth Quality of Service (QoS) for media associated with authorized services, the policy control rules server comprising:
a receiver configured to receive, from application devices, a number of previous service authorization requests and a subsequent service authorization request for a subscriber, each service authorization request respectively indicating associated media and bandwidth QoS required for the associated media; an authorizer configured to authorize the previous and subsequent service authorization requests; a rules generator configured to generate control rules for the previous and subsequent service authorization requests, respectively; and a sender configured to submit, to the application devices, respective authorization responses to the previous and subsequent service authorization requests, and configured to submit, to a policy enforcement device, respective control rules; storage configured to store a selective authorization criterion per subscriber, the selective authorization criterion selectable from a group of selective authorization criteria including:
service incompatibilities,subscribed bandwidth QoS per subscriber,pre-emption priority value per each service allowable for each subscriber, andcombinations thereof; a selector configured to select, amongst the previously authorized services, services that may be inactivated as a result of applying the selective authorization criterion for the subscriber; the authorizer being further configured to put on hold the selected previously authorized services; and the sender being further configured to submit, to the respective application device, a notification indicating those selected previously authorized services to be put on hold.
