摘要： According to a first aspect of the present invention there is provided a method of facilitating a communication session between a user terminal and an Application Function over an IP Connectivity Access Network. The method comprises, at a Policy and Charging Rules Function, receiving information relating to the session from the Application Function (B3), determining one or more Policy and Charging Control rules for the session including deriving a Quality of Service authorised for the session, and sending the Policy and Charging Control rules, including the authorised Quality of Service, to a Policy and Charging Enforcement Function (B5). At the Policy and Charging Enforcement Function, installing the one or more Policy and Charging Control rules including the authorised Quality of Service for the session, and, if it is determined that the authorised Quality of Service cannot be achieved due to a limitation on a Quality of Service available in the Access Network, then reporting this to the Policy and Charging Rules Function and including the available Quality of Service (B8). At the Policy and Charging Rules Function, receiving the report from the Policy and Charging Enforcement Function, including the available Quality of Service, and using the available Quality of Service to determine whether and/or how to maintain the session.

摘要： 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.

摘要： A method is provided of registering a mobile node (4), such as a User Equipment (UE), 5 of a telecommunications network, such as a Universal Mobile Telecommunications System (UMTS), to a subsystem of the network, such as an IP Multimedia Subsystem (IMS). The network has at least one node (13-1, 13-2), such as a Policy and Charging Rules Function (PCRF), for maintaining or having access to policy and charging rules for users of the network. The network also has at least one node (10), such as a 10 Gateway GPRS Support Node (GGSN), for enforcement of the policy and charging rules to traffic flows. A registration request message, such as a Session Initiation Protocol (SIP) REGISTER message, is received from the mobile node (4) at a proxy node (12), such as a Proxy Call Session Control Function (P-CSCF), of the network. In response, a candidate policy and charging rules node (13-2) is selected for the mobile 15 node (4), and it is determined whether the candidate policy and charging rules node (13- 2) has already been selected by a policy and charging rules enforcement node (10) to serve the mobile node (4). Subsequent steps of the registration procedure are performed in dependence on the determination.

摘要： 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. The PCRF includes a processing unit which produces a message having the accumulative quota usage from the memory and that is sent to the standby PCRF from the network interface unit every time an update request is received by the network interface unit so the standby PCRF can become an active PCRF when a switchover is required. The present invention is also directed to a method for 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).
