Abstract:
A method for preventing overload in telecommunications networks with IMS by always-on for a call received by a user. The user sends a request message in order to activate a new PDP Context to his SGSN, which sends it to a GGSN. The GGSN sends an Accounting Request message to an AAA server. If the GGSN is going to deactivate the user PDP Context for having been inactive, the association is not eliminated from an AAA server in which this association has been saved and, when an incoming call is received: the status of the user PDP Context is verified by an indicator, and if it is not active, the PDP Context is reactivated, and if the IP address has not been assigned to another user, an attempt is made to reactivate the PDP Context; and if said IP address has already been assigned, a restart is carried out after the failure of the call.
