Recovery of a system for policy control and charging, said system having a redundancy of policy and charging rules function |
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. |

1. A method 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 Internet Protocol Connectivity Access Network (IP-CAN) session is already established with a user entity (UE) and controlled by the second PCRF server, the method comprising:
receiving at a network interface unit of the first PCRF server 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 having 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; determining by a processing unit of the first PCRF server that the IP-CAN session is unknown; and sending 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 including all data required to be sent for the IP-CAN session establishment and synchronization data. |
