Abstract

The present invention discloses a disaster tolerance recovery method and system. The method includes the following steps that: a PCRF (policy and charging rule function) unit performs heartbeat detection on a first P-CSCF (proxy-call session control function) unit which provides services currently; if the first P-CSCF unit malfunctions, the PCRF unit sends a fault indication message to a PGW (packet gateway); when services associated with the first P-CSCF unit appear, the PGW sends a bearer update request to a user terminal associated with the services; the user terminal re-registers in a second P-CSCF unit which takes over the services of the first P-CSCF unit according to the received bearer update request, so that the second P-CSCF unit can bear the services. According to the disaster tolerance recovery method and system of the invention, a heartbeat detection mechanism is not required to be additionally installed between the PGW and the P-CSCFs, the resource consumption of equipment can be saved; when the PCRF detects the failure of the P-CSCF, it is not necessary to directly notify all users to re-initiate registration for the other P-CSCF unit which takes over the services of the P-CSCF unit, instead, re-registration is triggered based on the service request of the user terminal to complete a call task, and thus, the problem of the paralysis of the equipment caused by a condition that the equipment processes a large number of re-registration signals at the same time can be avoided, and the reliability of disaster tolerance recovery can be improved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a disaster recovery method and system. Background technique [0002] VoLTE (Voice over LTE, LTE-based voice service) is implemented through LTE and IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) networks. The LTE network provides 4G user access, and the IMS network provides 4G user voice services. The proxy call session control device (P-CSCF, Proxy-Call Session Control Function) is the entry node for 4G users to access the IMS network, the core network element of the IMS network, and the packet data gateway (PGW, Packet Gateway) and policy of the LTE network. It is connected with the charging control function equipment (PCRF, Policy and Charging Rules Function), and is mainly responsible for the proxy of user VoLTE service-related signaling and messages, and transfers the SIP (Session Initiation Protocol, Session Initiation Protocol) transaction of the vis...
