The invention provides a method of signalling interchange in IMS, able to reduce the number of the signalling interchange and improve system stability. In the signalling interchange among a network element, SLF and HSS, the method comprises sequentially the following steps: the network element receiving a message containing a user ID; according to the user ID, the network element querying in its buffer storage HSS information corresponding to the user ID; and the network element building signalling interchange with a home HSS determined by the HSS information. Thus, by adding the buffer storage to network element, the method reduces the interchanging process that I-CSCF queries SLF about the subscriber's home HSS. Therefore, the method reduces performance loss due to the number of IMS signalling interchange and improves system stability without changing the existing IMS network infrastructure and influencing the IMS session and service processing mechanism.
