METHOD FOR SWITCHING A PRIMARY HSS ON A BACKUP HSS IN AN IP NETWORK

摘要

The invention relates to a method for switching a primary HSS server on a backup HSS server in an IP network, said network including a plurality of CSCF servers (respectively, application servers) (C1, C2) wherein, after detecting a loss of connection between one of said CSCF servers (respectively, application servers) (C2) and a primary HSS server (H) to which said server is normally connected, said CSCF server (respectively, application server) (C2) connects to a backup HSS server (H'). The method also includes the following steps: a) a predetermined broadcast device is informed of said loss of connection with said HSS server (H); b) said broadcast device sends, at least to the other CSCF servers (respectively, application servers) (C1) that are normally connected to said primary HSS (H), a predetermined failure message containing the reference information from said primary HSS server (H); and c) said other CSCF servers (respectively, application servers) (C1) connect to said backup HSS server (H').
