TLDR
A rule-based communications service Architecture for the handover authentication mechanism was proposed, which could provide a heterogeneous network integration service architecture for the seamless transition of LTE and WIMAX networks without damaging the respective domains of the networks.Abstract:
With the increasing value-added services of information and mobile networks, the problem of insufficient bandwidth is posing the greatest challenge. To resolve this issue, the LTE (Long Term Evolution) of the 3G Partnership Project (3GPP) and the IEEE 802.16 Worldwide Interoperability for Microwave Access (WiMAX) are using IP-based next-generation network architectures to actively develop the 4G mobile communications network. The main purpose of this study was to examine the development and applications of the key technologies for the next generation heterogeneous mobile communications network architecture. On the basis of the Estinet7.0 simulation platform, this study simulated the implementation of interworking LTE and WiMAX scenarios. The core network architectures of LTE and WiMAX and their components’ functions were first introduced, and then the interoperability scenarios of 4G network technology co-existence and integration were analyzed. Next, this study explored the handover mechanism and other factors of consideration. Based on the signal sign, both in concept and in practice, a rule-based communications service architecture for the handover authentication mechanism was proposed, which could provide a heterogeneous network integration service architecture for the seamless transition of LTE and WIMAX networks without damaging the respective domains of the networks. The proposed architecture is expected to extend the interoperability between LTE and WiMAX systems in a simpler and faster way in the future.read more
