複数の無線ネットワークからシームレスにハンドオーバーするためのターゲット・ネットワークの選択

Document Type and Number:

Japanese Patent JP4585969

Kind Code:

B2

Abstract:

Method and device for deciding a handover of a communication link between a mobile device and a current network to one of a number of available networks, including determining network parameters for each if the available networks and determining a set of candidate networks basically suitable for handling the communication with the mobile device. From the set of candidate networks a target network is selected, based on a comparison of link parameters describing a communication link between the mobile device and each candidate network. A handover is then performed to the selected target network. The invention enables a seamless inter-network handover and avoids significant degradation of service or service termination.
