ABSTRACT:
The present invention relates to a method and terminal device for handling a suspended network state, wherein the end of a suspended network state is detected and subscription to a state event package is initiated in response to the detected end of suspension. Based on information given in a response to the subscription, registrations of user identities are updated. Thereby, the registration state of the user and the user's identities can always be kept actual, even after a suspension of the network connection.
