  • Publication number: 20130132570
    Abstract: The present invention improves control rules requests between reporting periods, and provides for enhanced PCRF and PCEF carrying out a method of controlling usage of network resources. This method comprises: determining at the PCEF events requiring control rules; requesting control rules and providing information about usage of network resources during the re-porting period from the PCEF to the PCRF; determining at the PCRF first control rules by using the information about usage of network resources; determining at the PCRF second control rules by using an initial value for usage of network resources during a next reporting period; submitting from the PCRF to the PCEF the first and second control rules; enforcing at the PCEF the first control rules received from the PCRF; and upon starting the next reporting period for the user, inactivating the first control rules and enforcing at the PCEF the second control rules received from the PCRF.

  • Publication number: 20130054800
    Abstract: A method of delivering data to user terminals connected to an Internet Protocol Connectivity Access Network, IP-CAN, wherein the IP-CAN implements a Policy and Charging Control, PCC, architecture. The method comprises caching data within an IP-CAN cache server upon a decision made by a Policy and Charging Rules Function, PCRF, of the PCC architecture. The cached data is then identified to a Policy and Charging Enforcement Function, PCEF, of the PCC architecture. At the PCEF, data requests made by user terminals are monitored and a determination made as to whether or not a request relates to cached data. If a request does relate to cached data, then that cached data is delivered from the IP-CAN cache server to the requesting user terminal.

  • Publication number: 20130044645
    Abstract: It is provided a method for handling policy and charging information, PCI, relating to a user, wherein the method is carried out in a communications network comprising a first and a second site at least (S1, S2). Each of these sites comprises at least a policy and charging rules, PCR, network entity. The method comprises sending (SI1O) from a first network entity of a first site (110; AF-1; PCEF-1) to a PCR network entity of said first site (PCRF-1) a request to obtain PCI dependent on a user profile; generating—if it is determined that said user profile is not accessible at the first site (PCRF-1)—a redirection message comprising an identity of the PCR network entity of the first site (PCRF-1); forwarding said redirection message to a PCR network entity of said second site (PCRF-2).

  • Publication number: 20130003529
    Abstract: The present invention is related to handling redundancy of a Policy and Charging Rules Function (PCRF) in a wireless communication network having an active PCRF, a standby PCRF and a Policy and Charging Enforcement Function (PCEF) by replicating accumulative quota usage of the active PCRF in a memory of the standby PCRF every time an update request is received at the active PCRF. The present invention is directed to a Policy and Charging Rules Function (PCRF) active in a wireless communication network having a standby PCRF and a Policy and Charging Enforcement Function (PCEF), wherein the PCRF includes a memory in which accumulative quota usage is stored. The PCRF includes a network interface unit which receives update requests.

  • Publication number: 20120136992
    Abstract: In a policy and charging control method carried out by a server including a policy and charging enforcement function (PCEF), identification information for identifying a particular service instance of a particular service type is obtained. When a packet is received, the PCEF determines whether the packet belongs to the particular service instance by using the identification information and by inspection of at least one of Open Systems Interconnection (OSI) layer n control information of the packet, wherein n is an integer equal to or larger than 3, and the packet's payload. If it is determined that the packet belongs to the particular service instance, the PCEF updates a usage parameter representing an accumulated usage associated with the particular service instance. The PCEF then makes available to a policy and charging rules function (PCRF), the usage parameter or information derived therefrom.

  • Patent number: 8175576
    Abstract: A method and apparatus for registering a mobile node such as a User Equipment (UE) of a UMTS telecommunications network with a subsystem of the network such as an IP Multimedia Subsystem (IMS). A Policy and Charging Rules Function (PCRF) node provides policy and charging rules, and a Gateway GPRS Support Node (GGSN) enforces the rules for traffic flows. The UE sends a registration request to the GGSN, which selects a PCRF. When a Proxy Call Session Control Function (P-CSCF) receives the registration request, the P-CSCF selects a candidate PCRF and validates the selection. If the candidate PCRF is the PCRF selected by the GGSN, the registration is successful. If not, the P-CSCF may select another PCRF and repeat the validation process.

  • Publication number: 20120023246
    Abstract: At present some situations occur where a policy control at individual user level is not enough. For example, where a plurality of users surpasses a load limit in a certain location area, which could imply a risk of network congestion, policy control decisions in conventional architectures have to be made by submitting corresponding orders for each user affected by the decision, thus resulting in a higher signalling and processing load. To overcome these drawbacks, the present specification provides for new network entities and method to monitor and control a plurality of users, as dynamically determined according to different selection criteria, in order to compile users-related aggregated reports, to establish dynamic group of users whom specific policy control rules can be applied, and to map orders and information between group and user level.
