  • Method for carrying out a transfer procedure in a radio communication system for a packet-switching connection and radio communication system suitable for the same
    Patent number: 7257100
    Abstract: A packet-switching connection is set up from a mobile station through a first transceiver unit, whereby the mobile station is assigned to a first cell and a first residence zone. As the mobile station moves to a second cell and a second residence zone, the connection is assigned a residence zone change identification. A transfer procedure for the packet-oriented connection from the first cell to the second cell is carried out. After the transfer procedure a data exchange by the packet-switched connection is reestablished. After reestablishing the data exchange a procedure for residence zone exchange is carried out.

  • Method and network element for distributing and directing data packets during a handover of a mobile transceiver station from a first radio cell to a second radio cell within a mobile communication network
    Publication number: 20070047488
    Abstract: A method and network element for distributing and directing data packets during a handover of a mobile transceiver station from a first radio cell to a second radio cell within a mobile communication network, especially during a packet-switched cell handover. The network element of the mobile communication network via which a communication to the second radio cell is directed is provided with data packets that have been duplicated by at least a part of the data packets forwarded to the first radio cell. In this manner, the network element determines the type of distribution and direction of the duplicated data packets without any additional signaling.

  • Mechanism to support high speed circuit switched data services via an iu interface
    Publication number: 20060007861
    Abstract: Method for initiating a HSCSD call set-up in a cellular mobile telecommunication system, wherein a RAB Assignment message is sent between a switching device (3G-MSC or MGW) to a base station controller (GERAN-BSC), containing the description of allowed multislot configurations for the HSCSD call which is to be initiated.
