Abstract
A method for preventing overload in telecommunications networks with IMS by always-on for a call generated by a user, in which process the user makes a PDP Context request and a GGSN of said network provides a free IP address to him or her and the PDP Context becomes active. An S-CSCF of the network creates a record in which an association between the IP address and a characteristic identity of the IMS network is included. When the GGSN is going to deactivate the PDP Context for having been inactive for a preestablished time, an indication of such deactivation is sent to the IMS client which maintains the characteristic IMS identity-IP address association and marks it as fictitious. When the user generates a new call, the IMS client informs the UMTS terminal about the characteristic IMS identity-IP address association marked as fictitious, and the UMTS terminal sends a PDP Context request message, in which message the IP address of the IMS association is included.
