Abstract

The invention discloses a method and system for simulating a borderless network channel environment. The method comprises: a control background of an iNES generates a corresponding wireless network channel script, base station configuration updating data and UE background configuration data for each test period T0(n), wherein n is equal to 1,..., N, and the N expresses the number of test periods; and during system testing, a base station background dynamically updats the state of each base station according to the base station configuration updating data of each test period T0(n); a wireless network channel simulation module of the iNES dynamically updats a simulation network environment according to the wireless network channel script of each test period T0(n); and a UE background drives designated UE to initiate a service call according to the UE background configuration data of each test period T0(n). Therefore, simulation of a large-scale network channel environment can be realized.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and system for simulating a borderless network channel environment. Background technique [0002] A wireless channel is an image metaphor for the path between the sending end and the receiving end in wireless communication. The propagation of radio waves in a wireless channel is not a single path, but a synthesis of many reflected waves from many paths. Since the distances of radio waves passing through each path are different, the arrival time of reflected waves from each path is different, that is, the time delay of each signal is different. When the transmitter sends a very narrow pulse signal, the signal received by the mobile station is composed of many pulses with different delays, which is called delay spread. [0003] Due to the mobility of the mobile station in mobile communication, as mentioned above, there will be Doppler effect in the wireless channe...
