Problems solved by technology

[0007] However, this method needs to upgrade the eNodeB, and there are many eNodeBs in the wireless communication network, which makes the cost of this method very high, and although this method can realize bearer control for different PS services, different PS services are assigned different Air interface resources, but unable to implement interception and access control of different PS services

Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0040] The present invention mainly expands the DPI module on the PGW at the core network side, identifies the service type through the DPI module, and sends the identified service information to the PCRF through the extended Rx interface by the DPI module, and the PCRF sets different PS service types according to different PS service types. QoS policy, and inform the PGW of the QoS policy; PGW controls the EPS bearer of different PS services according to the received QoS policy, so that different PS services are established on different EPS bearers, and different QoS parameters will be set according to the bearer in the wireless layer , carry out different priority processing on the bearer, so as to achieve better QoS guarantee for high-priority PS serv...

Abstract

The invention discloses a load-bearing control system in EPC (evolved packet core) based on DPI (depth package inspection). The system comprises a DPI module, a PCRF (policy and charging rules function) and a PGW (packet gateway). The DPI module is used for identifying service content through the DPI, acquires information used for service quality QoS decision-making of a service, and sends the information to the PCRF. According to a pre-established control policy and DPI module report information used for QoS decision-making, the PCRF is used for the QoS decision-making, and sends determined QoS rules to the PGW. When exchanging data with UE (mobile terminal), the PGW sends all exchanged data with the UE to the DPI module for recognition. According to the QoS rules sent by the PCRF, bearing control process to the service is initiated. The invention further discloses a load-bearing control method in the EPC based on the DPI. With the system and the method, load-bearing control to different PS (packet domains) services is achieved, intercepting and visiting control to the different PS services can be achieved, and realization cost is lower.

Description

technical field [0001] The present invention relates to the technical field of long-term evolution (LTE), in particular to a deep packet inspection (DPI)-based bearer control system and method in packet core evolution (EPC). Background technique [0002] Long Term Evolution (LTE) is an advanced mobile network technology that is currently developing rapidly. As the network evolution architecture of the LTE packet domain, the Evolved Packet Core (EPC) unifies the packet domain and the circuit domain, and is the core network connecting the mobile network and the external network. Its specific architecture is as follows: figure 1 As shown, it includes a mobility management entity (MME) 103, a serving gateway (SGW) 104, a policy and charging function entity (PCRF) 105, and a packet data network gateway (PGW, or PDN GW) 106. The mobile terminal (UE) 101 can connect to the external network through the base station (eNodeB) 102, MM / SGW, and PGW, so as to access the data content pro...
