In the high-speed rail scenario since the high-speed rail run at a speed of more than 300 km/h and the high user density, it will cause high handover frequency and a large number of the handover request at the same time. Build the mobile relay node (MRN) on the high-speed rail to perform the group handover for the user is the most feasible method. However, when MRN performs the handover with gateway relocation, it needs to send the path switch request per UE, resulting in a large number of signaling overhead. In this paper, we proposed a group handover with gateway relocation mechanism that MRN can send a representative message and trigger the path switch for all UE under the same group therefore reduce the handover latency and signaling overhead. And our scheme can apply for different MRN architecture.
