  • Multicast transmission in a cellular network
    Patent number: 7606587
    Abstract: The invention relates to a mechanism for performing multicast transmission in a cellular network. In order to enable establishment of resources only in cells containing members of the multicast group and to avoid congestion on the uplink channel, a multicast service notification is transmitted to mobile stations, thereby informing members of the multicast group of an upcoming multicast session. The moment for a response to said multicast service notification is selected in the mobile stations and a presence report is sent from at least one of said mobile stations at the response moment of said at least one mobile station. The presence report or reports are received within a radio access network, and radio resources are established for multicast transmission in a cell of the cellular network when the presence report(s) received in said cell meet(s) predetermined criteria.

  • System and method for collision-free transmission scheduling in a network
    Patent number: 7580394
    Abstract: A system and method is directed to enabling a collision-free transmission of a packet in a network by employing an access-point tree optimized MAC (ATOM) mechanism. The system enables a node in an ad hoc network to determine a collision-free transmission schedule based in part on information the node has about a distance to an access point along a routing tree rooted at the access point. The node may be assigned a time slot for collision-free transmission based in part on a bandwidth demand at the node, and traffic the node has to forward on behalf of a neighbor node.

  • Arranging mobile-to-mobile connections in wireless telecommunications system
    Patent number: 7567538
    Abstract: Mobile-to-mobile connections are being arranged in a wireless telecommunications system comprising at least one mobile station, base stations serving the mobile stations, and at least one gateway. The gateway controls the base stations connected to the gateway and performs a protocol conversion. For mobile-to-mobile connections, a second handover algorithm is stored in the gateway. The data transmitted between two mobile stations served by base stations connected to the same gateway is switched in the gateway without a protocol conversion. If a mobile station is engaged in a data transfer connection with another mobile station visiting the wireless telecommunications system, the mobile station is handed over, when necessary, to a base station proposed by a second handover algorithm.
