自组织网络（SON）方案监视某些关键性能指标（KPI），并通过调整系统控制参数来响应。多个SON方案可以具有相关的KPI或者使用相同的控制参数。这导致这些方案及其用例以建设性或破坏性的方式进行交互。在本文中，我们研究了三个SON用例之间的这些相互作用，所有这些都旨在改善LTE毫微微小区网络中的整体切换过程。这些用例即：切换自优化、呼叫接纳控制自优化和负载均衡自优化。这项工作的动机是缺乏相互作用的研究，到目前为止，这三个自我优化的用例之间进行。首先，我们调查了相关的单个方案提案，以确定在我们的交互研究中代表这三个用例的方案。然后，几个互动实验进行了现实的情况下，使用我们的内部建成和LTE兼容的仿真环境。我们得出结论，我们认为可以帮助设计人员实现更好的协调政策之间的这三个与互联网相关的SON用例。
A Self Organizing Network (SON) scheme monitors certain Key Performance Indicators (KPIs) and responds by adjusting system control parameters. Multiple SON schemes may have related KPIs or use the same control parameters. This leads these schemes and their use cases to interact either constructively or destructively. In this paper, we study these interactions between three SON use cases all aiming at improving the overall handover procedure in LTE femtocell networks. These use cases are namely: handover self optimization, call admission control self optimization and load balancing self optimization. This work is motivated by the lack of interaction studies conducted so far between these three self optimization use cases. First, we have surveyed related individual scheme proposals in order to identify schemes which represent these three use cases in our interaction study. Then, several interaction experiments are conducted in realistic scenarios using our in-house built and LTE-compliant simulation environment. We conclude by drawing guidelines that we believe can help designers realize better coordination policies between these three handover-related SON use cases.
