Embodiment
[0047]With the large-scale construction of the LTE network, the workload of single-site network optimization is heavy. Only through the analysis method of drive test and PM traffic statistics index, the problems existing in the network can be found and solved. Due to some defects, the network quality and quality cannot be guaranteed. In-depth discovery of problems in the network leads to unsteady optimization work in the early stage, and it will cost twice as much to solve in the future, which brings great challenges to the centralized maintenance and optimization of LTE networks; through the combination of user Internet signaling and the whole process of business, it can be found Compared with other data transmission processes, the TCP three-way handshake process has the advantages of less transmitted data packets, all network elements (terminals, eNBs, SGWs, SPs) throughout the end-to-end process, and no need for DNS server resolution and SP server scheduling processing. , wh...

The invention discloses an LTE network service downlink rate estimation method and an LTE network service downlink rate estimation device. The method comprises the following steps: determining a preset time delay threshold according to the pre-measured corresponding relationship between the downlink rate and TCP time delay in an LTE network; monitoring whether the current TCP time delay in the LTE network exceeds the preset time delay threshold, and outputting an evaluation result if the current TCP time delay exceeds the preset time delay threshold; and generating prompt information indicating that network parameters related to the current TCP time delay need optimization according to the evaluation result. By monitoring the current TCP time delay, an evaluation result reflecting the degree of influence of the current TCP time delay on the downlink rate is obtained. TCP time delay includes core network side time delay and wireless network side time delay. When the downlink rate is poor, whether a fault occurs at the core network side or at the wireless network side can be judged accurately according to the evaluation result. Positioning and delimiting of factors affecting the service rate in the LTE network is realized. The centralized maintenance optimization efficiency of the LTE network is improved effectively, and the service awareness of users is ensured.
Description
technical field [0001] The present invention relates to the field of LTE networks, in particular to a method and device for evaluating downlink rate of LTE network services. Background technique [0002] With the flattening of the LTE network architecture, network maintenance and optimization tend to be centralized. In the existing technology, drive tests or analysis of PM traffic statistics indicators are often used to locate problems such as cell interference, weak coverage, low speed, and poor access success rate. Optimization, this method has two defects: [0003] The method of finding problems through road tests has limited test analysis scope, small test sample size, large data burst and volatility, and high test costs. Only problems are found, and the link where the problem is located cannot be found in depth; [0004] Through PM traffic statistics indicators, such as RRC, E-RAB success rate, disconnection rate, PRB utilization rate, single PRB throughput rate, user ...
