Mutual interface verification center and mutual interface verification method

Abstract

The invention relates to the field of test and discloses a mutual interface verification center and a mutual interface verification method. The method comprises the following steps of (A) respectively collecting receptivity data of a to-be-verified module at one frequent point no matter whether an interference source module works or not and verifying whether the frequency point is an influential frequency point according to the collected data; (B) if the frequency point is determined as the influential frequency point, recording each parameter information of the frequency point, controlling an attenuator to adjust a parameter index of a verification scene, respectively collecting the receptivity data of the to-be-verified module at one frequent point no matter whether the interference source module works or not until a mutual interference critical point of the frequency point is found, or determining that the frequency point has no mutual interference critical point; (C) adjusting a working frequency point of the interference source module and repeating the steps A to B until all working frequency points of the interference source module are traversed; and (D) adjusting the working frequency points of the to-be-verified module and repeating the steps A to C until all working frequency points of the to-be-verified module are verified. According to the mutual interface verification center and the mutual interface verification method, the mutual interface verification can be carried out conveniently and efficiently.

Description

technical field [0001] The invention relates to the field of testing, in particular to a mutual interference verification center and a mutual interference verification method. Background technique [0002] The multiple transceivers inside the mobile terminal (referred to as "UE") are relatively close to each other. For some coexistence scenarios, for example, for different access technologies, the operating frequencies in the same UE are relatively close. The current filtering technology cannot prevent interference Do enough suppression. For example, ISM (Industrial Scientific Medical, Industrial Scientific Medical) (Industrial Scientific Medical Band Industrial Scientific Medical Band is defined by ITU-R (ITU Radiocommunication Sector, International Telecommunication Union Radiocommunication Bureau) and LTE (Long Term Evolution, 3GPP long-term evolution), When ISM transmits, the reasons for its mutual interference are mainly two aspects. One is that the large transmit powe...

Problems solved by technology

Due to the huge amount of total evaluation data for the complete verification of ISM and LTE mutual interference, the existing technology cannot provide a basis for product design optimization in a short period of time, which will affect the time to market or performance of the product, and ultimately reduce the competitiveness of the product
