  • Patent number: 10778851
    Abstract: The present invention relates to methods and nodes for managing network resources in a policy and charging system of a communication network, as well as to a system comprising at least one of the described nodes, and to a computer program, which provide for optimizing the resources of a telecommunication network and to reduce memory usage. A method for managing network resources in a policy and charging system of a communication network comprises receiving at a second node an indication about a state of a server resource of a first node; determining whether or not an activity of a service session associated with a connection between a client and the second node is below an activity threshold; and if the activity is determined to be below the activity threshold, instructing a termination of a bearer resource assigned to the service session.

  • Patent number: 10476970
    Abstract: For authorizing redirection services in a policy and charging control architecture, a policy and charging control rules function (PCRF) server determines control rules and redirection information per service in an internet protocol connectivity access network session, and a policy charging and enforcement function (PCEF) device receives control rules and redirection information per service basis, determines redirection per service request, and triggers the redirection. Upon a first request for a service, the PCEF device returns a redirection message with a redirection identifier; and upon completion of the service redirection, the first request for the service reaching the PCEF, the PCEF verifies the service is authorized and submits a service allowance toward the service server in charge of the service. Methods are also disclosed.

  • Patent number: 10455382
    Abstract: Handling a plurality of Presence Reporting Areas, PRAs, may currently present inconsistencies between the PRAs active in a policy controller and those PRAs active in a network node handling UE mobility, e.g. MME/SGSN. To overcome these and other drawbacks, there are provided enhanced policy controller, network node and method of handling a plurality of PRAs. This method comprises selecting, at the policy controller, a plurality of applicable PRAs; transmitting from the policy controller, and receiving at the network node, the plurality of applicable PRAs; selecting, at the network node from the plurality of applicable PRAs, a number of PRAs to be active at the network node; and transmitting from the network node, and receiving at the policy controller, at least one of: an indication on whether a UE is inside or outside a PRA, and an indication on whether a PRA is or is not accepted to be active by the network node.

  • Publication number: 20180332120
    Abstract: The present invention faces the issue of authorizing redirection services in PCC architecture and provides for a PCRF server adapted to determine redirection per service in an IP-CAN session, a PCEF device adapted to receive redirection information per service basis, to determine redirection per service request and to trigger the redirection; and a method of authorizing a redirection service in a PCC architecture, comprising: upon an IP-CAN session establishment or modification, a PCEF device requesting control rules; a PCRF server determining services requiring redirection and answering with control rules and redirection information per service basis; installing at the PCEF device the control rules and redirection information; upon a first request for a service, the PCEF device determining the service redirection and returning a redirection message with a redirection identifier; and upon completion of the service redirection, the first request for the service reaching the PCEF, the PCEF verifying the service

  • Patent number: 9998343
    Abstract: For event reporting between a first node and a second node of a mobile telecommunications network, the second node sends an indication to the first node to subscribe to reporting of a certain event type by the first node. The indication may specify that a change in type of radio access technology, as used by a user equipment for connecting to the telecommunications network, is to be reported from the first node to the second node. The second node may provide additional information to the first node to further specify a subtype of the event to be reported. The additional information may specify at least one type of radio access technology. Based on detecting the event of the specified event type and subtype, e.g., a change to or from a specific type of radio access technology, the first node sends a report of the detected event to the second node.

  • Publication number: 20150236914
    Abstract: The present invention relates to a method and a node for controlling resources for a media service in a policy and charging system of a communication network carried out by a network node including a policy and charging rules function obtaining information from another node so as to optimize network resources. The method of controlling resources comprise the steps of obtaining, at a network node, identification information for identifying at least one of a user and a user terminal; determining at least one device parameter using said identification information, which parameter is associated with a device selected to receive media data of said media service; and selecting according to said at least one device parameter a policy which is to be applied for said media service.
