摘要： A first Policy and Charging Rules Function "PCRF" server for recovery of a Policy and Charging Control "PCC" system. The PCC system also has a second PCRF server previously in charge of controlling an Internet Protocol Connectivity Access Network "IP-CAN" session previously established with a UE, and a PCRF-client. The first PCRF server includes a network interface unit of the first PCRF server arranged for receiving a modification request of the IP-CAN session from the PCRF-client after failure of the second PCRF server which was in active mode. The first PCRF server has a PCRF identifier which is shared with the second PCRF server that has failed. The first PCRF server now in active mode. The modification request requesting new rules for the IP-CAN session, including modification data and excluding access data and supported features for the IP-CAN session. The first PCRF server includes a processing unit of the first PCRF server arranged for determining that the IP-CAN session is unknown, and arranged for submitting a request from the network interface unit of the first PCRF server to the PCRF-client to provide all information that the PCRF-client has regarding the IP-CAN session. The information includes all data required to be sent for the IP-CAN session establishment and synchronization data. A Policy and Charging Rules Function "PCRF"-client for recovery of a Policy and Charging Control "PCC" system. Methods for recovery of a Policy and Charging Control "PCC" system with a first Policy and Charging Rules Function "PCRF" server in standby mode, a second PCRF server in active mode, and a PCRF-client, wherein an IP-CAN session is already established with a UE and controlled by the second PCRF server. A computer program embodied on a computer readable medium for recovery of a Policy and Charging Control "PCC" system.

摘要： A method and apparatus for handling a communication session in a communications network. An Application Function node receives a request to register a user terminal in the communication network. The Application Function identifies an Access Point used by the terminal to register with the network, and send a request message to a Policy and Charging Register Function (PCRF). The request message includes an Access Point Name identifying an Access Point used by the user terminal. The AF receives a response message from the PCRF, the response message including an indicator indicating whether the Access Point is an Emergency-Access Point. The AF subsequently receives a message from the user terminal that identifies a non-emergency terminating node. If the indicator indicates that the Access Point is not an Emergency-Access Point, the AF allows the communication session. If the indicator indicates that the Access Point is an Emergency-Access Point, then the AF rejects the communication session.

摘要： A policy controller (30) of a mobile network receives an authorization request (302) for a packet-based service from a node (80). In response to receiving the authorization request (302), the policy controller performs an authorization check (305) to determine an authorization status of the service and sends an authorization response (306) to the node (80). The authorization response (306) indicates the authorization status of the service. In response to the same authorization request (302), the policy controller (30) performs at least one further authorization check to redetermine the authorization status of the service. If the further authorization check indicates that the authorization status of the service has changed, the policy controller (30) sends a status change message (311) to the node. The status change message (311) indicates to the node (80) that the authorization status of the service has changed.

摘要： A method is provided for use in a telecommunications network. A first message is received (S1 ) at an application function (10). The first message relates to a request for a service involving the establishment of a data flow between a first terminal and a second terminal. The application function (10) is associated with the first terminal for the service. A second message is sent (S3) from the application function (10) to a policy control function (20). The policy control function (20) is associated with the first terminal for the service. The policy control function (20) is assigned to determine at least one policy to be applied to the data flow. The second message comprises first information relating to at least one characteristic of the service that is common with respect to the first and second devices. The second message also comprises second information relating to (a) whether the service is an originating or terminating service with respect to the first terminal, or (b) whether the first terminal is to be considered as an initiator of the service or a recipient of the service; these can be regarded as being equivalent. The second message is received (S4) at the policy control function (20). The second message comprises the first and second information. At least one policy is determined (S5) at the policy control function (20) based on the first and second information received in the second message. A third message is sent (S6) from the policy control function (20) to a gateway node. The gateway node is associated with the first terminal for the service. The gateway node is assigned to enforce at least one policy to the data flow. The third message comprises the at least one determined policy.
