  • Overload protection in packet communication networks
    Patent number: 7466983
    Abstract: Methods of handling messages at an interface in a communication system include the steps of receiving a message having an information element indicating the message's type, determining whether a frequency of receipt of messages of a predetermined type exceeds a threshold, handling the message in a normal way if the frequency does not exceed the threshold, and discarding the message if the frequency exceeds the threshold and the message is of the predetermined type. Such methods are useful in avoiding overloads after re-starts of serving GPRS support nodes or base station systems in packet-switched communication systems.
    Type: Grant

  • Methods and means related to the maintenance of connections in a gprs network
    Patent number: 7324556
    Abstract: This new invention is a method of re-establishing MS-SGSN connections after a partial restart of SGSN, i.e., only the Gb-interface is restarted. The re-establishment is achieved without detaching the MS. With this method Ciphering is re-synchronised, PDP-contexts in unacknowledged mode are re-established, and SMS traffic over GPRS is re-established, while PDP-contexts in acknowledged mode are deactivated with order to re-activate. When the MS is moving within the coverage of a SGSN, the invention can be used to move the context closer to the used Gb-link. When the MS request better Quality of Service, the MS context can moved to more suitable SGSN resource with this invention.

  • Migration of downlink traffic in GPRS
    Patent number: 6778500
    Abstract: The present invention relates to a method for improving the traffic handling capacity of a packet switched mobile telephone communication system. In said system there is introduced a load sharing function between the Base Station System and the Serving GPRS Switching Node. The purpose of the load sharing function is to distribute the traffic load from the SGSN to a BSS among the available Network Service Virtual Channels.
