  • Method of arranging data transfer in a wireless telecommunication system
    Publication number: 20090232099
    Abstract: A method of arranging data transfer in a wireless telecommunication system comprising at least one wireless terminal, a first radio access gateway and a first base station connected thereto, a second radio access gateway and a second base station connected thereto. The first base station and the first radio access gateway are arranged to transmit data between the terminal and an end point in an IP-based network. Address information on the second radio access gateway is specified to the first radio access gateway when it is detected that handover from the first base station to the second base station is needed for the terminal. Data directed to the terminal is transmitted through the first radio access gateway and the second radio access gateway to a wireless network after the terminal has been handed over to the second base station.
