Problems solved by technology

However, when the dual standby works at the same time, there is a possibility of concurrent services. For example, while one module is answering a call, another module may receive an incoming call request; the emergence of concurrent services requires two radio frequency systems of dual-mode dual-standby mobile The mutual interference performance between the

Embodiment Construction

[0038] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] Referring to FIG. 1 , it illustrates a schematic diagram of instrument connection for the wireless interference test proposed by the present invention. As shown in Figure 1, the GSM dual-mode dual-standby mobile phone has two independent GSM radio frequency transmitting and receiving systems, which are called G1 and G2 respectively. The two radio frequency systems G1 and G2 can be in the working state of wireless communication at the same time. It is connected to a wireless comprehensive tester through a power splitter, and the spectrum analyzer is connected to the above two power splitters through a power splitter.

[0040] In order to ensure the accuracy and reliability of the mobile phone wireless interference test, the test system should work in a shielded room, or place the tested GSM dual-mode dual-standby mobile phone in a shield...

Abstract

The invention discloses a method for wireless interference tests of a GSM dual-mode dual-standby mobile phone, provides a method for testing wireless interference produced by a first radiofrequency system and a second radiofrequency system of a GSM dual-mode dual-standby mobile phone under the same frequency and the same time slot, and a method for testing the wireless interference of adjacent channels produced by the first radiofrequency system and the second radiofrequency system of the GSM dual-mode dual-standby mobile phone under different frequencies and the same time slot, as well as a method for testing the wireless interference produced by secondary harmonic of an EGSM900 frequency band to a DCS1800 frequency band of another radiofrequency system of the GSM dual-mode dual-standby mobile phone. The invention roundly and effectively tests the degree of mutual interference between the two radiofrequency systems of the GSM dual-mode dual-standby mobile phone, and assures the communication quality of the GSM dual-mode dual-standby mobile phone.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for wireless interference testing of a dual-mode dual-standby mobile phone. Background technique [0002] At present, mobile communication systems mainly include GSM and CDMA networks. CDMA / GSM dual-mode dual-standby and GSM / GSM dual-mode dual-standby products are all newly emerging products. CDMA / GSM dual-mode dual-standby mobile phones and GSM dual-mode dual-standby The mobile phone adopts two complete sets of radio frequency transmitting and receiving systems. When the two sets of radio frequency systems work at the same time, it will inevitably cause the problem of mutual interference of wireless signals. For CDMA and GSM dual-mode dual-standby mobile phones, the frequency bands of CDMA and GSM networks overlap for a while, and the CDMA receiving frequency band overlaps with the GSM transmitting frequency band; however, the modulation methods of the two are comple...
