Reporting link layer status information using heterogeneous network handover module in mobile communication system

摘要

The present invention relates to link layer status information using a media independent handover module in a mobile communication system, wherein packet loss attributed to congestion can be identified from packet loss attributed to non-congestion. Preferably, the present invention comprises establishing communication between a mobile terminal and at least one of a homogeneous and heterogeneous network, reporting status information of a radio link connecting the mobile terminal and the at least one of a homogeneous and heterogeneous network to a heterogeneous network handover module of the mobile terminal, and reporting the status information of the radio link from the heterogeneous network handover module to an upper management entity of the mobile terminal if the heterogeneous network handover module determines a predetermined condition is satisfied.
