Impact of packet forwarding during Inter-eNodeB handover via X2 interface

This paper analyses the impact of packet forwarding during Inter-eNodeB handover via X2 interface. Performance issues with regard to providing enough capacity at the X2 interface, handling of packets to forward at the source eNodeB are analyzed. The analysis shows that to provide better application performance, proper dimensioning of the X2 interface is required taking into account the anticipated traffic from cells and mobility patterns of users. It further shows that the high sensitive packets need priority in forwarding them to the target eNodeB.
