To achieve that data rate, 5G mobile personal cell (mPC) is an emerging technology to provide ubiquitous connectivity to the users according to the traffic load and situations. In this paper, we provide a brief survey on the architecture and features for the 5G mobile personal cell in the context of the 3GPP LTE-A. More specifically, this paper highlights the key differences in the mPC architecture from the existing 3GPP LTE-A architecture. In mPC architecture, there is an additional personalized cell domain that helps users to ubiquitously connect with less transmission delay by supporting high mobility and data rate. Moreover, the key features of mPC such as its load balancing capability, capacity boosting, capability to cope with the disasters situations, and seamless mobility support regardless of the cell types and radio access technologies (RATs) are discussed. In addition, the suitable deployment scenario for the mPC is also discussed. Finally, we present possible challenges and point out the directions for mPC research. Keywords—5G mobile personal cell, LTE-A, SDN controller, ubiquitous connectivity I. INTRODUCTION The recent studies on 5G mobile communications systems show that the usage of small cells in order to achieve the broadband services for mobile devices [1]. 5G system is targeting higher data rates, low power consumption, large number of connected devices, high mobility applications, and low latency applications as compared to existing 4G system [2]. To achieve these targets, the existing technologies proposed under the 4G architecture needs the paradigm shift [3-4]. Thus, the technologies and techniques like massive multiple-input multiple-output (MIMO), device-to-device (D2D) communications, utilization of higher frequency bands, and moving networks are discussed [5]. Almost all the technologies in [5] are targeting network-centric architecture except the concept of moving networks. The moving networks are targeting the user-centric network to provide same user-experience everywhere. Moreover, some of the possible technologies and standardizations trends for 5G mPC is also discussed in [6]. The mPC has the advantage of providing the coverage extension in case of fixed cells. In addition, the mPC can provide the services like multi-hop D2D communications in case of disaster situations and is well suited in internet of things (IoT) because of its capability to provide low latency. The rest of the paper discusses the architecture, deployment scenarios, challenges, and open research issues in the mPC. II. ARCHITECTURE AND DEPPLOYMENT SCENARIOS FOR MPC A. Mobile Personal Cell Architecture 1) Literature review: The standardization processs of mPC is still in on-going phase. In [6], the possible scenarios and architecture for mPC has been proposed. The architecture proposed in [6] rely on the exisiting LTE architecture for the mPC. Similary, in [7] the authors discussed the moving cells suitability for vehicular users under the existing LTE architecture. Thus, the proposal is not suitable in context of mobile personal cell that needs to be managed centrally to efficiently tackel the interference problems in the ultra dense network (UDN) deployment. In order to upgrade the existing LTE architecture, we proposed mPC arhcitecture based on LTE architecture by using the concept of software defined networking (SDN). *Address correspondence to Prof. KyungHi Chang. 164 978-1-4673-7116-2/15/$31.00 ©2015 IEEE ICTC 2015
