A unified service‐based capability exposure framework for closed‐loop network automation
Transactions on Emerging Telecommunications Technologies, Volume 33, Issue 11, November 2022., 2022 In this article, we motivate the need for an enhanced network exposure functionality for network automation. We motivate it by revising the state of the art, propose a candidate architecture, and proof its feasibility with a real world testbed.

Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022 Mobility management is essential in mobile communication networks to provide a smooth connection during users’ mobility. Handover control parameters (HCPs), such as handover margin (HOM) and time‐to‐trigger (TTT), are major and essential factors in mobility management that must be defined carefully to make efficient handover (HO) procedures.

Decentralized Vehicular Mobility Management Study for 5G Identifier/Locator Split Networks
Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022 The identifier/locator split (ILS) architectures are highly promising to reduce the signaling latency of frequent handovers in fifth generation (5G) networks, while decentralized vehicular mobility management holds greater potential than the traditional centralized management to enhance the critical performance of highly dynamic and dense cell networks.

The Handover and Performance Analysis of LTE Network with Traditional and SDN Approaches
Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022 The mobility of user equipment (UE) in cellular network is a challenging issue in terms of its management. Current traditional handover in Long‐Term Evolution (LTE) network is managed by evolved Node B or eNodeB (eNB) which is a decentralized solution. In contrast to existing technology, software defined network (SDN) has the capability of serving the ...

Research on Adaptive Handover Decision Algorithm in Next‐Generation High‐Speed Railway Scenario
Mobile Information Systems, Volume 2022, Issue 1, 2022., 2022 For the 5G‐R wireless communication system of the next‐generation high‐speed railway, there is a problem of single algorithm consideration when handover is carried out. In high‐speed environment, it is easily affected by handover risk, which leads to the problem of low handover success. To solve the above problems, this study proposed a next‐generation
