  • Publication number: 20140026197
    Abstract: A mechanism to handle conflict situations relating to a situation in which an intended SON operation at or near the domain's boundary (border area) may impact on one or more cells in a neighboring domain comprises a single-domain coordinator that assesses whether there may be an impact on the neighboring domain, and if yes, requests an inter-domain, coordinator to check and assess whether there is a conflict.

  • Patent number: 8023435
    Abstract: The present invention relates to a method and network node for distributing a network parameter information among network nodes of a transmission network. A spanning tree of routing paths corresponding to the shortest paths from said network node to other nodes is determined based on a topology information of the transmission network, and is used to distribute the network parameter information from the network node to the other network nodes. Thereby, the updating message or packet traffic can be reduced dramatically as compared to the conventional flooding scheme.

  • Publication number: 20110211514
    Abstract: The present invention relates to methods, apparatuses, a system and a computer program product for reducing interference and energy consumption of wireless devices. An apparatus, namely a femto base station or home (e) NodeB, can include a transmitting unit, a receiving unit, a determining unit, a disabling unit, a disabling handshaking unit, and a reassigning unit. If the determining unit determines that there is no active communication between the apparatus and a user device, the disabling unit may disable the transmitting unit and the receiving unit while maintaining a connection between the apparatus and a network. A disabling handshaking can be performed by the disabling handshaking unit to achieve this, wherein the re-assigning unit may re-assign one or more user device(s) to a network apparatus, namely a macro (e) NodeB.

  • Patent number: 7813505
    Abstract: Sequence numbers for data packets to be transmitted using bearers having bearer identifiers in a communications system are generated, wherein the sequence numbers are generated independently for each of the bearers used for transmitting the data packets. Last generated sequence numbers for each of the bearers identifiers are stored and held in a memory. When a sequence number for a data packet to be transmitted using a bearer out of the bearers which has been used before is to be generated the memory is checked on a last generated sequence number for the bearer with a previously used bearer identifier and the sequence number is generated in accordance therewith.

  • Patent number: 7406071
    Abstract: The invention provides a GeoIP resolving system (GIRS) which is able to resolve between the IP addresses and the geographic location of servers/hosts/access ports in a wide area network, in particular the internet. GIRS servers are provided which contain resolution tables indicating the correlation between IP addresses and geographic positions of servers/hosts/access ports. The GIRS system can be accessed by indicating a certain geographic area wherein the GIRS system responds by listing all IP addresses of servers/hosts/access ports located in the indicated geographic area. In addition, the service types provided or requested by the found servers/hosts/access ports may be listed. The GIRS system can also be accessed by specifying an IP address. The GIRS system then responds by issuing the geographic coordinates of the location of the host having the indicated IP address and, maybe, the associated service, policy server, as well as administrated area.
