Embodiment 1
[0063] An embodiment of the present invention provides a borderless network channel environment simulation system, such as figure 1 As shown, the system includes: wireless network channel simulation system iNES, base station system and UE system; wherein, iNES includes: control background (hereinafter referred to as iNES background) and wireless network channel simulation module (hereinafter referred to as iNES front); base station system includes : several base stations (BTS), and the base station background; the UE system includes: several terminals (UE), and the UE background.
[0064] Wherein, the iNES external interface includes interfaces with multiple UEs, interfaces with multiple BTSs, and interfaces with UE background and base station background (network management OMC). The external interface between iNES and UE / BTS supports baseband IQ and radio frequency signal interfaces, which are used for the transmission of uplink and downlink signals.
[0065] Based on the ab...
Embodiment 2
[0084] An embodiment of the present invention provides a method for simulating a borderless network channel environment, which is applied to the system described in Embodiment 1, such as figure 2 As shown, the method specifically includes:
[0085]Step S201, the iNES background generates corresponding wireless network channel scripts, base station configuration update data and UE background configuration data for each test cycle T0(n); wherein, n=1,...,N, N is the number of test cycles;
[0086] Step S202, during system testing, the base station background dynamically updates the status of each base station according to the base station configuration update data of each test period T0(n); the iNES front desk dynamically updates according to the wireless network channel script of each test period T0(n) Simulate the network environment; the UE background drives the specified UE to initiate a service call according to the UE background configuration data of each test cycle T0(n)...
Embodiment 3
[0097] An embodiment of the present invention provides a method for simulating a channel environment in a borderless network. This embodiment discloses more technical details to better illustrate the specific implementation process of the solutions described in Embodiments 1 and 2 of the present invention.
[0098] This specific embodiment is aimed at the LTE system, such as image 3 As shown, the iNES foreground and the UE and the base station (eNodeB) adopt radio frequency signal interfaces, and are connected through radio frequency cables. It is well known in the industry that when performing equipment function / performance tests in the laboratory, the power amplifier and antenna may not be connected, and the radio frequency signal may be directly extracted through the radio frequency interface, which is provided by both the terminal and the base station. The interface between the iNES background and the UE background is connected by a wireless WiFi interface. The interface...
