WiMAX double-mode mobile phone as well as switching method thereof

Abstract

The present invention provides a WiMax dual mode cellphone, employing a WiMax processor module as a main processor of the cellphone, connecting with a GSM processor module or an EDGE processor module by serial ports, the GSM processor module or the EDGE processor module are used as a slave processor, the main processor and the slave processor are separated to allocate SIM cards, sharing a LCD display, a keyboard, a horn, a headphone, a microphone, the audio channel switch between the main processor and the slave processor processes switching audio channel and voice information by an audio simulation switch and a corresponding interrupt signal collector. The invention also provides a switching method of the WiMax dual mode cellphone, realized by transmitting interrupt to the WiMax processor module by the GSM or EDGE processor module as the slave module. The invention reduces allocation requirements of the main frequency or slave frequency of the CPU, capable of freely controlling the sleep state of the cellphone, greatly reducing the standby power consumption, and improving the performance of the RF.

Description

Technical field [0001] The invention relates to a mobile phone, in particular to a dual-mode mobile phone using WiMax network for communication. The invention also relates to a switching method for WiMax dual-mode mobile phones. Background technique [0002] WiMax is the abbreviation of World Interoperability for Microwave Access (World Interoperability for Microwave Access). It is based on the IEEE 802.16 standard. Its original intention is to provide point-to-multipoint broadband wireless access in a metropolitan area network multi-vendor environment. Therefore, WiMax It is also often called IEEEWireless MAN (Metropolitan Area Network). This technology involves the work of two international organizations: IEEE802 Standards Committee 802.16 Working Group and WiMax Forum. The IEEE802.16 working group is the standard maker; the WiMax Forum is the promoter of IEEE802.16 technology. [0003] As an emerging wireless communication technology, WiMax can provide high-speed Internet-orie...

AI Technical Summary

Problems solved by technology

The dual-mode mobile phone that uses time-sharing scanning must have high requirements for this timing, that is to say, the control time-sharing scanning mechanism must be above 7.5MHz. Therefore, the entire design system must be very demanding, including the CPU. The configuration is improved, and the power consumption of the mobile phone is increased, because this scanning is impossible to stop

If the information collection method of I / O port inquiry is used, the sampling frequency of the I / O port must be at least 8Mbps, and at the same time, it is necessary to collect information in real time, so it is difficult to enter sleep mode

In addition, the requirements on the RF radio frequency are extremely high, because a crosstalk pulse is enough to prevent the scanning circuit from working
