Method for handover of terminal, network element, base station, and communication system

摘要

The present invention relates to a method for handover of a mobile terminal from a first network to a second network, a network element, a mobile terminal, a base station and a communications system as well as a computer program product and a storage medium. The method comprises the steps of: determining a WDP including an unnecessary handover probability and a missing handover probability according to conditions of the first network and the second network; detecting at least of the following: whether the unnecessary handover probability is greater than the missing handover probability, whether the unnecessary handover probability is greater than a specific threshold and whether the missing handover probability is smaller than a specific threshold; and making a handover decision based on the detection result. The present invention can select a more suitable target network for handover at a more suitable time, thus ensuring the continuity of a mobile user's call.

1. A method for handover of a mobile terminal from a first network to a second network, comprising:
determining a wrong decision probability (WDP) according to conditions of the first network and the second network, wherein the WDP includes an unnecessary handover probability and a missing handover probability and the conditions include at least application requirements and available bandwidth on the networks; detecting at least one of the following: whether the unnecessary handover probability is greater than the missing handover probability, whether the unnecessary handover probability is greater than a specific threshold and whether the missing handover probability is smaller than a specific threshold; and making a handover decision based on the detection result and the application requirements.
