  • Patent number: 10111155
    Abstract: Embodiments herein include methods and arrangements for controlling access of mobile devices to a network, such as GSM. The mobile devices belong to an access control class (ACC) and also belong to an additional access control class (EACC) that provides extended access control. The arrangement broadcasts system information to the mobile devices that comprises a first indicator indicating an ACC. The first indicator indicates whether a mobile device is allowed to access or is barred from accessing the network. The system information further comprises a second indicator indicating an EACC. The second indicator indicates whether a mobile device is allowed to access or is limited from accessing the network. Limited access may entail blocking a mobile device from initiating communications with the network, blocking the mobile device from receiving network initiated communications, or both. A mobile device blocked from network initiated communication may not answer a page from the network.

  • Patent number: 9985821
    Abstract: Methods and apparatus for correlating event notifications between agents in a management network are provided. An agent constructs a network notification in response to receiving an event notification. If the received event notification is associated with a prior notification already received and stored by the agent, a correlation attribute is added to the constructed network notification. If the received notification matches a peer agent notification category that another agent in the management network is interested in receiving, the constructed network notification is sent to the other agent.

  • Patent number: 8787214
    Abstract: Method and arrangement in a relay node, for selecting communication mode. The relay node is configured to communicate with a base station via a donor antenna over a first link and to communicate with a user equipment via a coverage antenna over a second link. The method comprises obtaining an isolation value, based on the radio wave isolation between the relay donor antenna and the relay coverage antenna. The obtained isolation value is compared with an isolation threshold level value. The relay node is configured to communicate in full duplex mode if the obtained isolation value exceeds the isolation threshold level value, otherwise in half duplex mode. Information concerning the configured duplex mode of the relay node is transmitted to the base station. Also a method and arrangement in a base station is described.

  • Patent number: 8752107
    Abstract: A system and method for time-shifting and chase-play for an IPTV system. A control channel is established between an originating user's set top box (STB) and an IPTV Application Server (IPTV-AS) utilizing SIP signaling over an IP Multimedia Subsystem. For time-shifting, the STB sends a start time-shifting command to the IPTV-AS over the control channel, and the IPTV-AS sends a start recording command to a Network Private Video Recorder (N-PVR). When the user is ready to resume viewing, the STB sends a start chase-play command to the IPTV-AS to establish a unicast channel. The IPTV-AS sends a playback command to the N-PVR to begin playback of the time-shifted content.

  • Publication number: 20140126403
    Abstract: Systems and methods for obtaining effective measurements in a cellular communications network are disclosed. In one embodiment, a node (i.e., a measuring node) in a cellular communications network performs a reference measurement at the node, where the reference measurement contains one or more interference components. The node then mitigates at least one of the interference components contained in the reference measurement to thereby provide an effective measurement. In one embodiment, the effective measurement is used by the measuring node, reported to another node, or both used by the measuring node and reported to another node.

  • Patent number: 8554235
    Abstract: An apparatus (20) is associated with a telecommunications node (N) which serves a service area (S) which belongs to one set of plural sets of service areas comprising a network. The apparatus (20) divides a time resource for the node into plural phases in coordinated manner with other service areas. The apparatus (20) further generates a schedule for transmission/reception of user traffic for wireless terminals served by the node for plural consecutive phases. The schedule is generated so that during the plural consecutive phases the node can transmit and receive scheduled user traffic before receiving in the plural consecutive phases scheduling information from another node which serves another set of service areas.

  • Publication number: 20130176850
    Abstract: A method enables a switch in a split-architecture network to provide high speed packet processing and enhanced network functionalities that are not supported by the OpenFlow. The switch receives a packet from a network through an input port of the switch, and matches header fields in the packet against table entries in flow tables to identify an action to be taken. The flow tables are part of an OpenFlow pipeline. The identified action is to direct the packet to a designated processing unit in the switch. The OpenFlow pipeline forwards the packet to the designated processing unit via a communication channel in the switch. The designated processing unit processes the packet with the enhanced network functionalities, and injects the packet back to one of the flow tables before transmission of the packet to the network through an egress port of the switch.
