METHOD AND SYSTEM AND MEDIA INDEPENDENT SWITCH APPARATUS FOR WIRELESS-NETWORK ENVIRONMENT DETECTION AND REPORTING IN NETWORK HANDOVER

摘要

A method and a system for radio network environment detection and reporting in a network handover and a media independent handover (MIH) apparatus are provided. The method includes the following steps: an MIH function (MIHF) at a terminal side initiates a network scan, and generates a parameter report on a radio network environment around the terminal including dynamic information and static information of a scanned point of access (PoA) after the scan is completed; the MIHF at the terminal side sends the parameter report on the radio network environment to an upper layer at the terminal side or to an MIHF at a network side. The technical solutions support homogeneous and heterogeneous network environments at the same time, thereby increasing the accuracy of selecting a target PoA when the network side initiates a handover and improving the network handover efficiency.
