The present invention relates to IMS technical field, in particular relates to a session controller disaster recovery technology, and discloses a method and device of session control, failure of the session controller to solve the user binding, resulting in UE can not be timely registration or session can follow the problems. In the user registration process initialization, the address information storage PCSCF users are bound to HSS, so that when the user calls, the available address information SCSCF can be called user bound PCSCF from HSS, and according to the PCSCF address information to inform the user re initialization register, or implement session continuation; further, the information stored in the user's address to DHSS, so that when the user calls, the available address information can be obtained from the ACSCF called user in DHSS, and according to the address information to inform the user of the called user registration or re initialization, implement session connection.
