本文主要是針對未來LTE Advanced電信系統之服務品質進行研究，同時導入PCC(Policy Charging Control)機制，提出當網路負載過重時，能夠確保重要數據達到Quality of Service服務品質要求，同時提高網路頻寛的高效能運行，進行一連串各種網路服務的實際分析測試，以及在特殊狀態下是否能夠兼具VIP用戶的滿意度，提出改善方案，並且以數據方式呈現出流量行為之變化。
行動通訊網路技術漸漸朝向高頻寛、高速度在演進，用戶能夠在網路上使用的服務種類如雨後春筍般愈來愈多，這些服務種類不外乎為影像、訊息、語音居多。其中以影像所佔用的數據量最為大，以往電信公司為了能夠滿足用戶頻寛的需求，增加設備擴充頻寛，但隨著用戶的數據量大幅快速增加，擴充設備增加頻寛的方式遠不及數據量的成長速度，同時也增加了電信公司的成本，降低了獲利空間，所以在有限的傳輸頻寛當中，必須要定義一個適當的Policy Management Control的機制，彈性的頻寛調度，避免少數用戶獨佔資源，減少電信公司成本的支出，同時兼具用戶的服務品質。
透過定義合理限制用戶頻寛的條件，將用戶的數據使用量及評估網路最為擁塞的時間，同時考慮是否在不限制頻寛的特定地點之基地台，加以整合這三種條件式，制定出一套管理機制服務策略之方法，提升用戶端的滿意度及系統面上有效的提高傳輸使用率。

With the development of wireless technologies and application services are switching to multimedia-oriented data communications from voice-oriented ones, the next generation mobile communication system is supposed to provide QoS(Quality of Service) and satisfy more users based on higher transmission rate.

The thesis is mainly for future LTE Advanced QoS service quality of telecommunication systems, research into PCC(Policy Charging Control) mechanism was proposed when the network is heavily loaded, to ensure that critical traffic QoS quality of service requirements, while ensuring the efficient operation of the network, research for network services. In addition, the state must take into account the special VIP customer satisfaction, identify solutions, and to display the QoS data changes.
Through policy rule formulation, can reduce the cost of telecommunication companies purchase equipment, while also addressing a few users, excessive use of a particular service, resulting bandwidth exclusive, and waste, affecting VIP users or the general interests of the users.

Finally, the experimental verification strategy system, understand the policy management mechanisms adopted method can enhance client satisfaction and effectively improve the transmission utilization.
