A mobile terminal comprises a registering functionality which is adapted to register terminal-based information about one or more missed call events which are not accepted by a user. Network-based information about one or more missed call events or voice messages registered by a PLMN to which the mobile terminal is subscribed is received. 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, a method is provided for registering information about missed call events in a PLMN comprising at least an IP Multimedia Subsystem (IMS) which is responsible for packet data services. An incoming call received by the IMS from a calling terminal originally destined to a called mobile terminal 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.

Upper layer applications discover, establish and manage the QoS connectivity through a SIP (session initiation protocol) that serves as a unified interface. In one implementation, this is IP Multimedia Subsystem-centric, further supporting applications that utilize SIP for session control. This capability extends to the data card universe allowing UMTS data card vendors to establish concurrent QoS-based sessions using multiple primary PDP (packet data protocol) contexts based on a set of SIP triggers, further allowing applications running on a computing system to transparently utilize the established pipes based on the individual QoS requirements.

An Application Server entity in an IP Multimedia Subsystem (IMS) network comprises an interface for interfacing with an application and control logic which is arranged to inspect signalling information received from the application via the interface in the form of Extensible Markup Language (XML). The received signalling information is compared with stored rule data which specifies a relationship between an element in the signalling information and an action that should be taken and output data is generated based on the comparison. The Application Server can output operational measurements and / or charging information which more accurately reflect usage made of the Application Server resources. The need for a separate OSA / Parlay-X gateway can be avoided.

A service control method, device and system for allowing secure, remote access of protected IP-based content delivered over an IMS-based network to one or more devices within a home network. The method involves a remote access device transmitting a remote access request to a service control application in the IMS-based network, the service control application authorizing the remote access request based on a number of criteria, and forwarding the remote access request to the home network. The forwarded remote access request includes information that allows protected content requested by the remote access request to be transmitted from a home network device in the home network to the remote access device upon appropriate verification of the remote access device by the home network device using home network device DRM schemes. Remote access of the protected content can be allowed by relaxing proximity restriction requirements of the home network.

A system and method that enables session-based and non-session-based application services to be controlled and managed within the IMS / NGN architecture. The IMS / NGN architecture includes a service layer and a transport layer. IMS service control functions are implemented within the service layer, and RACF and transport functions are implemented within the transport layer.
