Coverage self-optimization method of cellular mobile communication system

The invention relates to a coverage self-optimization method of a cellular mobile communication system, and is used for solving the problems of poor coverage, polluted pilot frequency and cross-area coverage. The method comprises the following steps of: measuring and reporting respective reference signal received power (RSRP) and respective signal-to-interference plus noise ratio (SINR) parameter values to a base station by each user; collecting the measurement parameter values reported by all users in a cell by the base station; judging whether the current network is in accordance with any one trigger condition of the three coverage problems; triggering a coverage self-optimization process based on dynamic adjustment on a lower dip angle of an antenna if the current network is in accordance with the condition and then adjusting the lower dip angle according to a preset scheme to solve the coverage problem; continuously adjusting an antenna azimuth angle and wave beam width or performing down-regulation on transmission power of the base station according to specific scenes and user types if the coverage requirement cannot be met within the adjustable ranges of the lower dip angle; and entering a coverage and capacity self-optimization process if the coverage problem cannot be solved by the measures. According to the method, each cell periodically initiates coverage liberalization operation for many times according to the steps so as to save manpower and material resources required by manual optimization and reduce the maintenance cost and the expenditure.

Method of correction for non-contact thermometry in translucent medium environment

The invention relates to a method of correction for non-contact thermometry in a translucent medium environment, which belongs to the technical field of pyrometry. The problem that when the surface of an object to be measured is in a translucent medium coverage environment, radiation energy detected through a traditional method can not be corrected through a traditional material surface emissivity correction method, so that the actual temperature can not be obtained is solved. The method comprises the following steps of: firstly, judging whether a translucent medium is contacted with the surface of the object to be measured, if so, selecting a one-dimensional coupling heat exchange model, adopting a finite volume method to calculate a forward model, and obtaining a theoretical radiation energy value capable of being obtained by temperature measuring equipment; if not, selecting a one-dimensional pure radiation heat exchange model, adopting the finite volume method to calculate the forward model, and obtaining the theoretical radiation energy value capable of being obtained by the temperature measuring equipment; then measuring an actual radiation energy value of the surface of theobject to be measured; and adopting an intelligent particle swarm optimization algorithm to inverse an actual temperature value of the surface of the object to be measured. The method provided by theinvention is applied to temperature measurement of the surface of the object to be measured in the translucent medium environment.

Area target coverage method for imaging satellite based on primary coverage band maximization

An area target coverage method for an imaging satellite based on primary coverage band maximization is provided. A satellite changes a side view angle with a preset angle as a step length every time,meshes of a primary coverage area are scanned and covered by an instantaneous field angle, and attributes of mesh points covered by push-sweep every time are adjusted. After the side view angle and cover area of push-sweep every time are recorded, the attribute value of the mesh of the coverage area is reset. Finally, a push-sweep angle covering the maximum mesh area is selected to add into a sideview scheme. If a plurality of primary coverage areas exist and the maximum push-sweep area after instantaneous coverage is the same, the side view coverage band with the largest actual coverage areais selected in the target area to determine the side view angle, otherwise the instantaneous coverage with the maximum push-sweep area is selected to determine the side view angle. The Area target coverage method for imaging satellite provided by the invention can effectively deal with large-scale situations, and greatly improves performance evaluation of time effectiveness, coverage rate, resolution and the like of area coverage of multiple kinds of imaging satellites under complex constraint conditions.

Method and device for judging cross-area coverage of communication cells

The invention provides a method and device for judging cross-area coverage of communication cells, relates to the technical field of networks, and solves the problems that a lot of human and material resources can be consumed and execution is relatively difficult when the cross-area coverage problem of the communication cells is judged through artificial road testing in the prior art. The method comprises the following steps of: obtaining Counter data of the switching successful time of cells, which is recorded by a system within a pre-set time period in a pre-set area, and network engineering parameters; selecting a cell A to be analyzed from the system, and taking the A as data of a target cell according to the Counter data, so that a first source cell list is generated; comparing the distance between each communication cell and the A in the first source cell list with 2*L(A) to find out a communication cell having abnormal switching with the A; and, collecting all communication cells having abnormal switching to generate a second source cell list, and judging that the coverage range of the A is normal when the number N of the communication cells in the second source cell list is less than or equal to 1. The embodiment of the invention is used for judging cross-area coverage of the communication cells.
