The current Evolved Packet Core (EPC) 4th generation (4G) mobile network architecture features complicated control plane protocols and requires expensive equipment. Data delivery in the mobile packet core is performed based on a centralized mobility anchor between eNode B (eNB) elements and the network gateways. The mobility anchor is performed based on General Packet Radio Service tunnelling protocol (GTP), which has numerous drawbacks, including high tunnelling overhead and suboptimal routing between mobile devices on the same network. To address these challenges, here we describe new mobile core architecture for future mobile networks. The proposed scheme is based on IP encapsulated within IP (IP-in-IP) for mobility management and data delivery. In this scheme, the core network functions via layer 3 switching (L3S), and data delivery is implemented based on IP-in-IP routing, thus eliminating the GTP tunnelling protocol. For handover between eNB elements located near to one another, we propose the creation of a tunnel that maintains data delivery to mobile devices until the new eNB element updates the route with the gateway, which prevents data packet loss during handover. For this, we propose Generic Routing Encapsulation (GRE) tunnelling protocol. We describe the results of numerical analyses and simulation results showing that the proposed network core architecture provides superior performance compared with the current 4G architecture in terms of handover delay, tunnelling overhead and total transmission delay. 5G network, mobile core network, GRE One of the greatest challenges for future mobile communication networks is how to design and build 5th generation (5G) mobile networks. The need for new network architecture is essential to support growth in demand for broadband services of various kinds delivered over the networks, and to support the Internet of Things (IoT) services and applications [2]. KEYWORDSMany approaches have been proposed to address the growth in data traffic on mobile networks, including device-to-device communication and radio resource management. However, these efforts have focused mainly on increasing the capacity of wireless radio links. The future mobile network consists of two main parts: a radio link and a non-radio mobile core network. Effective design of both the radio link and the mobile core is required to meet the requirements of the future mobile network [3].

Reaching a flat network is the main target of future evolved packet core for the 5G mobile networks. The current 4th generation core network is centralized architecture, including Serving Gateway and Packet-data-network Gateway; both act as mobility and IP anchors. However, this architecture suffers from non-optimal routing and intolerable latency due to many control messages. To overcome these challenges, we propose a partially distributed architecture for 5th generation networks, such that the control plane and data plane are fully decoupled. The proposed architecture is based on including a node Multi-session Gateway to merge the mobility and IP anchor gateway functionality. This work presented a control entity with the full implementation of the control plane to achieve an optimal flat network architecture. The impact of the proposed evolved packet Core structure in attachment, data delivery, and mobility procedures is validated through simulation. Several experiments were carried out by using NS-3 simulation to validate the results of the proposed architecture. The Numerical analysis is evaluated in terms of total transmission delay, inter and intra handover delay, queuing delay, and total attachment time. Simulation results show that the proposed architecture performance-enhanced end-to-end latency over the legacy architecture.

The current Evolved Packet Core (EPC) 4th generation (4G) mobile network structure emphasizes complicated control plane protocols and requires expensive equipment. In this approach, we propose the creation of a tunnel that maintains data delivery to mobile devices until the new Base Station (BS) element updates the route with the gateway, which prevents data packet loss during handover between BS elements located near to one another. To maintain the handover without losing the data we propose an approach scheme based on IP encapsulated within IP (IP-in-IP) for data delivery. We describe the results of numerical analyses showing that the proposed architecture provides superior performance compared with the current 4G architecture in terms of handover delay.
