Policy charging control-based business processing method and system in wireless network

Abstract

The invention discloses policy charging control-based business processing method and system in a wireless network. The method comprises the steps that: a SGW (Serving Gateway) sends an IP-CAN (IP Connectivity Access Network) bearing establishment request message to a PGW (PDN (Packet Data Network) Gateway); the PGW sends an IP-CAN conversation establishment indication message to a PCRF (Policy and Charging Rules Function) entity; the PCRF entity acquires the practical state information of the wireless network of a cell where UE (User Equipment) is located, and determines the IP-CAN bearing quality of an IP-CAN conversation and sends the IP-CAN bearing quality of an IP-CAN conversation to the PGW in combination with user subscription information, business related information and user roaming state information of the UE user; and based on the information of the IP-CAN bearing quality, the PGW establishes an IP-CAN bearing with the UE and returns an IP-CAN bearing quality establishment confirmation message to the SGW. According to the method and system, the execution efficiency of the PCC (Policy Charging Control) policy can be improved, the wireless network resources can be optimized, and the business processing efficiency of the wireless network can be increased.

Description

technical field [0001] The invention relates to communication technology, in particular to a service processing method and system based on policy charging control in a wireless network. Background technique [0002] Mobile communication networks began to introduce a flow-based policy control mechanism in the era of the 3rd Generation Telecommunications (hereinafter referred to as: 3G), and further improved it into a policy planning mechanism in the long-term network evolution (Long Term Evolution, hereinafter referred to as: LTE) stage. Policy Charging Control (Policy Charging Control, hereinafter referred to as: PCC) network architecture. An evolved packet core (Evolved Packet Core, hereinafter referred to as: EPC) network is a core network of an LTE network, and supports functions such as mobility management, session management, security, and policy control execution of the LTE network. After adopting the PCC network architecture, the EPC network has the ability to contro...

Problems solved by technology

[0005] At present, the sub-strategies based on the PCC strategy mainly come from the core network and service level, without considering the actual status information of the wireless network, including: the working status of the wireless network, the workload and processing capabilities of wireless devices, etc., for example, whether the wireless network Congestion, or whether the processing capacity of the base station cell has been overloaded. Therefore, the PCC strategy formulated only considering the core network and sub-strategies at the service level is not comprehensive and accurate, resulting in the failure or very low execution efficiency of the PCC strategy in some cases. The wireless network resources cannot be allocated reasonably, and the business processing efficiency of the wireless network is low
