Disclosed are a system and method for call session control function (CSCF) entity disaster tolerance and load balancing. Wherein, the system includes a proxy call session control function (P-CSCF) entity, an interrogation call session control function (I-CSCF) entity and a serving call session control function (S-CSCF), and also includes a domain name system (DNS) server. The present invention uses a DNS UPDATE message to report the load equivalent of the CSCF entity at regular time for the DNS server to use during the execution of the load balancing strategy, and it makes the disaster tolerance and load balancing of the IP multimedia subsystem (IMS) network be much easier to be used and extended, thereby the load of the IMS network is reduced. |
