  • Patent number: 9923622
    Abstract: A mobile communications system is described in which the network configures a mobile relay node that is mounted in a moving vehicle (such as a train) with expected tracking area information for the route along which the vehicle is expected to travel. UEs associated with the mobile relay node are provided with the list and do not perform tracking area updates if the movement of the vehicle corresponds to the stored list. Where advance knowledge of the route is not available, the mobile relay node is configured with a fixed tracking area and a fixed radio cell so that associated UEs do not detect a change in the tracking area or in the radio cell and so do not perform tracking area updates towards the network or the network does not need to control the UEs mobility while having a radio connection with the network.

  • Patent number: 9674334
    Abstract: Alarm messages are transmitted to subscriber terminals of a radio communication system by signalling the alarm presence through a control channel to the subscriber terminals by at least one base station of the radiocommunication system using at least one system information item. Upon reception of the system information item by the subscriber terminals, the subscriber terminals transmit at least one respective recorded alarm signal.

  • Patent number: 9516577
    Abstract: A method for managing ANDSF policies in a 3GPP access network includes defining ANDSF rules and structuring the ANDSF rules into sets of ANDSF policies. A set identifier is defined for each set of the ANDSF policies as an ANDSF Set-ID. The ANDSF Set-IDs are conveyed to targeted UEs via a 3GPP control plane. The sets of the ANDSF policies are provisioned to the targeted UEs. A respective one of the ANDSF Set-IDs is provided such that it is used by UE logic in order to apply the respective ANDSF policy.

  • Publication number: 20150049670
    Abstract: For allowing a very efficient service marking a method for operating a network, especially a mobile network, is claimed, wherein an ADC, which is co-located in a PCEF or separate in a TDF, detects data flows for reporting data flow-specific information to a control-plane node according to service-specific information received from said control-plane node. The method is characterized in that said service-specific information is provided to the ADC on a service context basis, and the ADC reports the data flow-specific information in the form of a service detection result to the control-plane node according to the service-specific information on a service context basis after having detected a new data flow and checked or identified to what service the new data flow belongs. Further, an according network is claimed, preferably for carrying out the above mentioned method.
