Recently, enormous growth of mobile data traffic can be load to operator's core network. Offloading traffic is a promising solution to alleviate the load. The 3GPP proposes the offloading solutions such as local IP access (LIPA) and selected IP traffic offload (SIPTO). Based on the LIPA/SIPTO, many relate works provides the offloading procedures and schemes but it doesn't take the network condition...
A handover (HO) is an important procedure used to maintain connectivity in mobile networks. Nevertheless, it is not sufficient when a user equipment associates with a certain base station for a very short period. In this letter, we propose an estimated time-of-stay-based cell selection (ETCS) scheme to minimize the number of unnecessary HOs that adversely affect the performance of heterogeneous mobile...
This paper proposes the mobility scheme based on an user perspective. First, we introduce the concept of the user-centric communication and present the protocol stacks of the User Equipment (UE) for supporting the user-centric mobility in Long Term Evolution (LTE) systems. We design a new protocol stack called Service Continuity Management (SCM). SCM has four functional blocks which is located between...
