ABSTRACT
To provide an always best connected service to the end user, the network provider needs to make best use of the various access networks available to the end-user. The infiltration of multi-mode terminals in wireless networks and the introduction of the Evolved Packet Core (EPC) in release 8 of the 3rd Generation Partnership Project (3GPP) specifications make a make-before-break handover an attractive feature to support in the core network, especially for real-time services which have stringent service continuity and packet loss requirements. Proxy Mobile Internet Protocol version 6 (PMIPv6) supports multi-homing where a multi-mode device can connect to more than one access network simultaneously. In this paper we extend the standard multi-homing support of PMIPv6 so that a make-before-break handover can be achieved in the EPC PMIPv6 adoption. A test-bed prototype of the scheme is implemented and testing is performed using IPTV as a model service for real time services. The results show that the proposed scheme outperforms the default PMIPv6 scheme in terms of packet loss and handover delay.
