METHOD AND DEVICE FOR HANDLING MISSED CALLS IN A MOBILE COMMUNICATIONS ENVIRONMENT

摘要

The present invention relates to handling and registering of information about missed call events in a mobile communications environment. A Method for handling information about missed call events and information about voice messages by a mobile terminal is provided. The mobile terminal comprises a registering functionality which is adapted to register terminal-based information about one or more missed call events, i.e. incoming calls which are not accepted by a user of the mobile terminal. The method comprises further receiving of network-based information about one or more missed call events registered by a PLMN to which the mobile terminal is subscribed. The network-based information about one or more missed call events may comprise additionally network-based information about one or more voice messages. Such network-based information occurs when the mobile terminal is not available or not reachable in the PLMN due to the fact that for example the mobile terminal is switched off or a call redirection is set. The network-based information is combined with the terminal-based information such that the mobile terminal is able to present the combined information to a user. Moreover, method for registering information about missed call events in a PLMN is provided that comprising at least an IP Multimedia Subsystem (IMS) which is responsible for packet data services. An incoming call is received by the IMS from a calling terminal originally destined to a called mobile terminal. The incoming call is redirected in accordance with Filter Criteria (FC) to the IMS and information about a missed call event in accordance with the incoming call is registered by the IMS. The at least registered information about the missed call event is stored by the IMS.
