Problems solved by technology

Depend on figure 1 It can be seen that the frequency spectrum distribution between different mobile communication systems may overlap, causing the same communication device (such as a mobile phone) to be unable to standby under different mobile communication systems with overlapping frequency spectrums at the same time
In addition, if a communication device executes Dual Mode and Dual Standby under two mobile communication systems with the same communication protocol, due to the close frequency and dual standby function, it is susceptible to mutual interference, causing Poor transmission quality or reduced sensitivity will affect the performance of communication devices

Abstract

The invention relates to a stand-by communication device simultaneous for multi mobile communication systems. A communicator can be used for the stand-by of a first mobile communication system and a second mobile communication system simultaneously. The communicator comprises a wireless signal transceiver module; a first receiver module which is used for the first mobile communication system to receive wireless signals; a first sending module which is used for transmitting wireless signals to the first mobile communication system; a second receiver module which is used for the second mobile communication system to receive wireless signals; a second sending module which is used for transmitting wireless signals to the second mobile communication system; a first filtering unit coupled to the first sending module and used for filtering out the part of overlapping bands between the signals of the first sending module and the received signals of the second receiver module; and a second filtering unit coupled to the second sending module and used for filtering out the part of overlapping bands between the signals of the second sending module and the received signals of the first receiver module.

Description

technical field [0001] The present invention refers to a communication device, especially a communication device that can be standby under multiple mobile communication systems at the same time. Background technique [0002] With the rapid and high-level development of wireless communication technology, light and convenient mobile phones have greatly changed the way people communicate with each other. Through mobile phones, people can exchange voice or information anytime and anywhere. According to different communication technologies, the known technology has developed many different mobile communication systems, including Global System for Mobile Communications (Global System for Mobile Communications, GSM), Code Division Multiple Access (Code Division Multiple Access, CDMA) communication system, broadband Code Division Multiple Access (WCDMA) communication system, Personal Digital Cellular (PDC) system, Personal Handyphone System (PHS), etc. According to different opera...
