example 1

[0054] Example 1: LTE (Long Term Evolution, long-term evolution) system handover algorithm test

[0055] Test scenarios such as image 3 As shown, there is a shopping mall near the edge of Community 1 and Community 2. Most of the users in the shopping mall move back and forth within the shopping mall. If the switching parameters are not set properly, the switching boundary is just near the shopping mall, which will easily lead to a high ping-pong switching rate. , the ping-pong switching will seriously affect the user experience and increase the switching failure rate. Relying on the existing simulation test system cannot solve this problem, because the user distribution and mobile model in the existing simulation test system are different from the actual scene, so the switching parameters obtained by simulation cannot solve the problem of the actual application scene, so it needs to be tested in the real The actual test is carried out in the field environment, and the switch...

[0084] Example 2: Interference Coordination Algorithm Test

[0085] The interference coordination algorithm uses UE RSRP (Reference Signal Receiving Power, reference signal received power) measurement report to distinguish center and edge users. Once it is determined that users enter the edge from the center or enter the center from the edge, RRC (Radio Resource Control, radio resource control ) The connection reconfiguration process reconfigures parameters such as power of the UE. The failure probability of the measurement report and the RRC connection reconfiguration signaling process has a key impact on the performance of the interference coordination algorithm, which will affect the judgment of the user's location information and the gain of the interference coordination algorithm.

[0094] Example 3: Business source test

[0095] Aiming at the problem that there is no classic business model for the emerging business at present, the idea of ​​this example 3 can be used to collect some business data in the existing network, read the data into the simulation test system, and use it as a business source in the simulation test system. The scheduling algorithm and resource allocation strategy can better guarantee the QoS (Quality of Service, service quality) of these services, and can adapt to the needs of the rapid development of existing services.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a simulation test method and equipment. Background technique [0002] The mobile communication system is a huge and complex system, it is difficult to describe it with a series of theoretical formulas and obtain accurate analytical solutions. Therefore, simulation has become an effective and fast means to analyze the mobile communication system. Simulation can be divided into link-level simulation and system-level simulation. System-level algorithms need to be evaluated using system-level simulation. System-level simulation reflects the performance of various network performance and various system-level algorithms by modeling the behavior of a large-scale mobile communication network. figure 1 It is a network model of a system simulation platform. The network topology in the figure uses the 19-site Wrap Around model. The network contains 19 eNodeBs (evolved NodeB, evolved N...
