  16. 16. Policy Control Responsible for offering applications that require the control per session or flow. Application It can forward to PDP setup information for taking Function decision and applying policy rules in any stage of session flow. Responsible for primarily making policy decision per session or flow basis. It authorizes QoS resources for each flow using the setup Policy information received via Application Server or PEP. Decision Point It can use of additional mechanisms and protocols (PDP) to achieve additional functionality such as user authentication, accounting, policy information storage, etc. Network resources Responsible for applying the policy rules from (transmission, access etc.) PDP, enforcing per session or flow basis the current allowed traffic contract. It receives a notification or a message that requires a policy decision. Given such an event, the PEP then formulates a request for a policy decision and sends it to the PDP. The PDP returns the policy decision and the PEP then enforces the policy Policy Enforcement Point decision by appropriately accepting or denying the (PEP) request.Network Architecture and Technology - Network Planning Area

CCA The PCRF subscribes to new event triggers or remove armed event triggers [Event Triggers Arm] unsolicited at any time or upon receiving event report or rule request from the PCEF (or BBERF). CCR [Event Trigger Report] The PCEF (or BBERF) performs event trigger detection. When an event matching PCRF the event trigger occurs, the PCEF shall report the occurred event to the PCRF.

  30. 30. Conclusions ► Rapid and consistent mobile broadband consolidation, air interface technology advances and machine type communication will bring a tsunami of IP data traffic. In the same time rapid service lifecycle forces new services to be mature quickly, with low profitability. ► Different users have different service expectations and application QoE requirements. Service customization based on device, network, access technology and location awareness is essential for fitting customer experience improvement with right cost. ► Policy & Charging Control is a powerful tool for capturing opportunities and any service lifecycle stage: Rating and charging services for developing compelling and competitive revenue models. Also PCC helps to transform data into customer-centric intelligence supporting revenue assurance via real-time revenue intelligence combined with monitoring and analysis. ► Unfortunately PCC architecture is still being formulated by SDOs with incipient definitions, and there is no consensus in terms of element network roles, interfaces and protocols. It is imperative to be created by operators a robust and proof of future network architecture vision. ► For mobile broadband services, 3GPP has a complete framework, but with mature definitions after release 8. In special, for location services, the event triggers are completely defined in release 8.40 with cellid granularity. ► Other location service architecture must be investigated, such as OMA SUPL that introduces more location accuracy, but it requires a terminal support and hard integration taskNetwork Architecture and Technology - Network Planning Area
