Embodiment Construction

[0071] The method of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0072] Coverage and capacity self-optimization method system device block diagram of self-organizing network SON in LTE / LTE-A, such as figure 1 As shown, the device is divided into four functional units in total, namely fault detection unit, learning matching unit, parameter decision-making unit and parameter configuration unit. Among them, the fault detection unit is used to detect the faults in the communication network in real time, and judge the current fault through the capacity fault detection and coverage fault detection; the learning matching unit includes the event learning function and the historical knowledge base. Event learning can quickly obtain the wireless parameter configuration that can be used to solve the current fault; the parameter decision-making unit includes a parameter correction module and a pa...

Abstract

The invention relates to a coverage and capacity self-optimization device of a self-organization network in LTE / LTE-A and a method thereof. A fault detection unit monitors faults related to the coverage and the capacity in real time in a mobile communication network, a learning and matching unit learns and matches with history event knowledge, and wireless parameters are initially configured according to the most similar event. Then a parameter decision unit adjusts the initially configured wireless parameters on the premise of taking account of the mutual influence of different wireless configuration parameters, and a utility function is introduced to evaluate the efficiency of the self-optimization process to finally finish the utility maximization on the premise of comprehensively taking account of network / business and the requirements of operators, and realize the coverage and capacity automatic optimization of the self-organization network in the LTE / LTE-A. The invention has the advantages that the invention realizes the accurate position of fault sources and the correct decision by using the existing coverage and capacity self-optimization model, thereby achieving the target of coverage and capacity self-optimization.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a device and method for self-optimizing coverage and capacity of an ad hoc network in LTE / LTE-A. Background technique [0002] In the future network, due to the coexistence of different networks, the network will become more complex, a large number of wireless parameters and data will greatly increase the workload of network optimization personnel, and operators hope to reduce operating costs and manual intervention. In this context, the self-organizing network SON (Self Organized Network) feature of the EUTRAN system is regarded as an important research direction of 3GPP. Self-organizing network SON is a concept proposed by mobile operators in the standardization stage of LTE networks. Its main idea is to realize some autonomous functions of wireless networks, reduce manual participation, and reduce operating costs. [0003] The self-organizing network SON is mainl...
