A method and device of session control are used to resolve the problem that when there is a failure in the session control function bound with the user, the UE can not re-login in time or the session can not be continued. In the flow of the user initial login, an address information of P-CSCF bound with the user in HSS is saved, so that when the user is called, an available S-CSCF can get the address information of P-CSCF bound with the called user from the HSS, and inform the user to do re-initial login according to the address information of P-CSCF or complete the session continuation; further, the address information of the user in D-HSS is saved, so that when the user is called, an available A-CSCF can get the address information of the called user from the D-HSS, and inform the user to do re-initial login according to the address information of the called user or complete the session continuation.
