Method and device for processing SRVCC switching, and terminal

摘要

A method and device for processing Single Radio Voice Call Continuity (SRVCC) switching, and a related terminal are disclosed. In a technical solution of the disclosure, two sets of authentication parameters can be stored during the process of SRVCC switching, one set of which is stored into a card and the other set is stored into a temporary data area, and specific access to the authentication parameters is controlled by a switch variable so that a user does not need to consider using which data area. It is determined, after the SRVCC switching succeeds or fails, whether authentication parameters in the temporary data area need to be written into the card. Calculated authentication parameters are directly written into the card after the SRVCC switching is started, so that update of the authentication parameters is more flexible and signalling interaction with a network can be reduced.
