Evolved Node B (eNodeB) monitoring system and eNodeB monitoring method

Abstract

The invention discloses an evolved Node B (eNodeB) monitoring system and an eNodeB monitoring method, which are applied to a long term evolution (LTE) network. The system comprises a UU air interface signaling acquisition module, a communication port programming interface (CPPI) / infrared (IR) interface signaling acquisition module, an intra-base band unit (BBU) signaling acquisition module, an S1 / X2 interface signaling acquisition module, an Ethernet switching module and a signaling analysis module. In the system and the method, analysis on control planes of an S1 interface and an X2 interface, each layer of a protocol stack in a BBU and a UU interface on a CPRI / IR link are combined to comprehensively analyze each kind of signaling of an eNodeB by the signaling analysis module to know the running conditions of the eNodeB, and data on a plurality of interfaces is associated for association analysis to solve the problem of comprehensive eNodeB signaling monitoring, so that comprehensive signaling monitoring can be performed for different interfaces, the problems of inconvenience of system maintenance and system instability caused by the adoption of different monitoring equipment are solved, and whole-course whole-network real-time association is realized; and the system and the method are favorable for the fault positioning of the whole network.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a base station monitoring system and a base station monitoring method. Background technique [0002] Long Term Evolution (LTE, Long Term Evolution) is in a stage of large-scale experimental network construction. In order to reduce the time delay of the LTE system, LTE adopts a flat architecture, and in the wireless part, there is only one network element device, a base station (eNodeB, also abbreviated as ENB). Therefore, the method of monitoring air interface signaling on the Iub interface between the Radio Network Controller (RNC, Radio Network Controller) and the NodeB adopted by 3G is not suitable for the LTE system. [0003] In the current LTE system, the base stations of various manufacturers generally adopt a distributed base station architecture, that is, the base station is composed of a base band processing unit (BBU, Base band Unit) and a remote radio unit (RRU...
