<p>A method and an apparatus for the backup of the subscriber service information are provided by the present invention. The method includes: a connection is established between a main service node and a standby service node by a predetermined protocol, and after the service types required to be backuped respectively by main/standby service nodes are determined by an ability negotiation, the connection and the main/standby state of the main/standby service nodes are associated in real time (101); when the subscriber service information varies, the main service node encapsulates, according to the main/standby state, the subscriber service information which corresponds to the service types required to be backuped by the standby service node, by a predetermined format, and identifies the subscriber service information for the different service types (102); the main service node transmits the encapsulated subscriber service information to the standby service node via the connection, so as to enable the standby service node perform backup according to the encapsulated subscriber service information (103). With the present invention, solved is the problem that the redundancy backup of the subscriber service information can not be implemented between the equipments of the different software platforms, and different protocols are required to backup the subscriber service information of multiple services.</p> |
