Embodiment Construction

[0025] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0026] In the development process of the existing communication network technology, the requirement for the simulation scale is getting higher and higher. In the embodiment of the present invention, a large-scale communication network is simulated by designing an algorithm. Among several concepts involved in the simulation process:

[0027] Polygon, a certain area drawn on the map.

[0028] planning area, a polygon on a map, a geographic area defined on a map during a simulation.

[0029] The simulation task means that each node of the distributed computer is responsible for the simulation work of an independent sub-planning area (sub-area for short), that is, a simulation task.

[0030] An embodiment of the present invention provides a method for simu...

Abstract

The embodiment of the invention provides a method and a device for simulating a communication network. The method comprises the following steps of selecting a simulation area in the communication network; dividing the simulation area into a plurality of adjacent first type of subareas; extending each first type of subarea by the first length along the respective subarea border, and using as a second type of subarea; packaging each second type of subarea into a simulation task, and obtaining simulation subdata of each second type of subarea obtained by the execution of the simulation task; combining the simulation subdata of the second type of subareas. The method has the advantages that the scale of the simulation area is larger, the simulation area is divided into a plurality of smaller subareas, the smaller subareas are sent to different simulation machines for simulating the subareas, and the large-scale simulation is decomposed into a plurality of simulation tasks, so the simulation efficiency is improved, and the problem of low speed of the large-scale simulation is solved.

Description

technical field [0001] The invention relates to communication network technology, in particular to a method and device for simulating a communication network. Background technique [0002] In current TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) and Time Division Long Term Evolution (TD-LTE, Time Division Long Term Evolution) network planning technologies, the simulation of the planning area is based on the planning area The circumscribed rectangle is simulated, and finally the simulation result in the circumscribed rectangle is clipped with the planning area. [0003] If there are many stations or a large area in the simulation area, the simulation or calculation efficiency of the current planning technology is low. The polygons with many stations or large areas in the simulation area include: oblique long polygons with large areas. When the circumscribed rectangle contains too many grids in the invalid area; in the planning area with a large area, the...
