In the proposed scheme, when Mobile Nodes (MNs) inside the mobile network needs to understand the condition of multiple comrmunicatinn paths outside the mobile netwtrk, they can get IP performance metrics, such as delay, jitter, bandwidth, packet loss, etc., irrespective of the preserre or absence of measurement functionality.

The Multihomed Mobile Router (MMR) with heterogeneons wireless interfaces measures IP performance metrics on behalf of the MNs inside the mobile network.

The proposed scheme can reduce burden and power consumption of MNs with limited resource and batty power since MNs don' t measure IP performance metrics directly.
