Session management system of LTE network

Abstract

The embodiment of the invention relates to a session management system of an LTE network. The session management system of the LTE network comprises a centralized performance platform which comprisesa first light interface; a PCRF network element, wherein the PCRF network element comprises a second light interface; the first optical fiber interface and the second optical fiber interface are connected through an optical fiber connector, so that the centralized performance platform is in communication connection with the PCRF network element; wherein the centralized performance platform is usedfor transmitting the congestion cell information and / or the quality perception information of the LTE network to the PCRF network element, and the PCRF network element is used for determining a response strategy for solving the congestion problem and / or the quality problem according to the congestion cell information and / or the quality perception information. According to the session management system of the LTE network provided by the embodiment of the invention, the PCRF network element can determine the response strategy corresponding to the network problem according to the analysis information of the centralized performance platform on the LTE network, so that the network problem can be efficiently and accurately solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a session management system of an LTE network. Background technique [0002] The construction method of each network element of the existing LTE network is generally a chimney construction, such as figure 1 As shown in , the centralized performance platform can collect the signaling plane information of the S1-mme interface and the media plane information of the Sgi interface in the LTE network respectively, and can rely on the processing functions of the big data platform to complete functions such as data analysis and data diagnosis , to determine important information such as the number of access users in the corresponding cell, the service download rate, the proportion of service types, and user behavior habits. However, this information is more used in subsequent research on business model parameters and network performance analysis afterwards. [0003] In addition, ...

AI Technical Summary

Problems solved by technology

[0003] In addition, existing LTE networks generally provide corresponding network capability services in the form of dumb pipes, such as figure 2 As shown, the LTE network uses a unified bearer mode for all services, resulting in the LTE network not providing differentiated service quality guarantees for different services

[0004] To sum up, the existing LTE network lacks timely and effective closed-loop management functions, and cannot adjust the LTE network in time according to the information of analysis and diagnosis. It is necessary to provide a solution that can accurately and efficiently solve network problems to ensure that LTE A session management system for network quality
