Abstract

In the Evolved Packet Core (EPC) network architecture for 4G mobile communication systems, the data delivery is performed based on the GPRS tunneling protocol (GTP) between eNodeB and the gateways. However, the use of GTP tunnels may give some drawbacks, which include large tunneling overhead for packet, non-optimal data paths between Mobile hosts within the same network, and frequent tunnel updates for every handover. In this paper, we propose a new architecture for mobile core network in the emerging 5G mobile systems. The proposed mobile core network architecture is based on the Transparent Interconnection of Lots of Links (TRILL) protocol for data delivery and mobility management, named TRILL-based Packet Core (TPC). In the proposed architecture, each eNodeB will function as a Routing Bridge (RB) of TRILL. The data delivery operations are performed between RBs by using TRILL switching mechanisms, rather than using GTP tunnels. The proposed architecture uses Mobility Management Entity (MME) to manage the mapping information between identifier (IP address of user equipment) and locator (MAC address of RB). For handover of user equipment, the location of users will be updated with MME. By numerical analysis, it is shown that the proposed 5G-TPC architecture can give more performance benefits than the 4G-EPC architecture in terms of data tunneling overhead, total transmission delay and route update delay after handover .
