It is widely anticipated that beyond 3G network will be an IP-based integration of heterogeneous wireless access technologies. "Seamless mobility" in such network is much more difficult to be achieved than in traditional wireless telecommunication networks because the B3G network environments are more complex, and various IP-based services presents various(More)
In order to reduce the handover latency to support the real-time application, Layer 2 trigger was proposed to help Layer 3 handover. However, the current Layer 2 trigger mechanism has two major problems. One is that Layer 2 trigger has non-unified interface with upper layer. And the other is that single parameter based trigger is not efficient to provide(More)
In this paper, we describe a method for text passage classification or extraction by means of supervised machine learning and analytically identifying passages. The underlying characteristic of the method lies in the utilization of the resulting classification, which leads to the classification of the portion of a document in a high dimensional feature(More)
Generally handover can be divided into two kinds, hard handover and soft handover, according to the connection situation with the base station. In the overlapped coverage area, while hard handover will cause more packet lost and handover cost, and soft handover can provide seamless handover performance. The soft handover can be implemented either in link(More)
