Transmission method, system and radio network controller
First Claim
1. A data transmission method in a telecommunication system, the system comprising at least two radio networks and at least one user terminal, the method comprising, a user terminal being served in a cell of a first network, if the neighboring cells of the serving cell in the first network are congested, choosing a cell in a second network as a handover target cell, performing a handover from the first network to the second network.

Abstract
A radio network controller, comprising: means for storing information on the loads of cells in a first network, means for storing information on the loads of cells in a second network, means for choosing a cell in the second network as a handover target cell, means for giving a handover trigger, means for controlling a handover from the network to which the radio network controller belongs to a different network.

2. A data transmission method in a telecommunication system, the system comprising at least two radio networks and at least one user terminal, the method comprising,
a user terminal being served in a cell of a first network, measuring neighboring cells of a subscriber'"'"'s serving cell belonging to the first network and to a second network and storing the measurement information, storing information on the loads of neighboring cells of a subscriber'"'"'s serving cell belonging to the first network, storing information on the loads of neighboring cells of a subscriber'"'"'s serving cell belonging to the second network, if the neighboring cells of the serving cell in the first network are congested, choosing a cell in the second network as a handover target cell, giving a handover trigger, performing a handover from the first network to a determined cell of the second network.
