Problems solved by technology

[0003] Under the existing technology, in the process of coverage test and capacity test, it is necessary to consider the influence of the same-frequency networking and different-frequency networking on the test results, and also need to consider the results of the neighbor cell and the cell with or without users. Therefore, if a real communication device is used as an interference terminal for testing, it will greatly increase the complexity and cost of testing

Embodiment Construction

[0022] In order to reduce the test complexity and cost input of the mobile communication system, in this embodiment, no real interfering terminal is used for testing, but by configuring simulation loading related parameters and setting at least one virtual interfering terminal to complete the test, wherein, The terminal under test still uses real communication equipment.

[0023] Wherein, the so-called simulated loading-related parameters may include but not limited to the following parameters, for example: the time-frequency resources (such as PDCCH resources or / and PDSCH resources) required to be loaded by the virtual interfering terminal, the loading ratio of time-frequency resources, Whether the loading start position of time-frequency resources is random, the MIMO (multiple-input multiple-output) method used when loading time-frequency resources (mainly for PDSCH resources), the number of forming angles, the change cycle of forming angles, etc., various The specific appli...

Abstract

The invention relates to the field of communication and discloses a terminal interference test realizing method and a device used for reducing the test complexity and the cost investment of a mobile communication system. The method comprises the following steps: loading at least one virtual interference terminal according to preset analog loading related parameters, and distributing a corresponding time frequency resource for the at least one interference terminal; and sending a signal to the at least one interference terminal on the time frequency resource so as to carry out interference test on other actual tested terminals. So, time frequency resources in a system can be respectively loaded, resource occupation modes, sending power and other parameters can be flexibly set, interference of a certain part of time frequency resources on the tested terminals in the fixed direction is easy to realize, and a multi-beam interference scene is easy to construct, so the execution complexity and the cost investment of an interference test process is effectively reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for realizing terminal interference testing. Background technique [0002] In the coverage test and capacity test of the mobile communication system, in order to verify the performance of the communication device in the real network, it is usually necessary to introduce certain interference in the test, that is, when testing the device under test, it is necessary to quote a certain number of interfering terminals . At present, in practical applications, real communication devices are usually used as interference terminals for testing, thus, a large number of real communication devices need to be used in the test. [0003] Under the existing technology, in the process of coverage test and capacity test, it is necessary to consider the influence of the same-frequency networking and different-frequency networking on the test results, and also need to consider the resul...
