Mobile telephone and its communication method

Abstract

A mobile telephone based on short-distance wireless communication technique is composed of a host and a hand set, which contain short-distance communication module and power supply for mutual communication. The said host has network communication module and short-distance communication module for mutual transmission of communication data. The said hand set has short-distance communication module and data processing and I/O controller. Its advantages include split structure, low radio radiation and convenient application.

Description

technical field [0001] The invention relates to a portable mobile phone, in particular to the technical field of the mobile phone using short-range wireless communication technology and the technical field of its communication method. Background technique [0002] On the one hand, with the development of modern technology, the continuous improvement of people's living standards, and the increase of various business volumes in the commercial society, people's demand for various mobile communication services is increasing indefinitely. In the real world, people's dependence on mobile handheld devices has increased. Communication through wireless means is not limited to voice services. A mobile phone with multiple functions has been launched, which will inevitably challenge the size, weight and battery capacity of the device. The time spent using the mobile phone to talk, send faxes, surf the Internet, etc. has increased absolutely. The battery capacity of the mobile phone with...

Problems solved by technology

However, its handset unit includes a signal processing / control unit, a transmitting module connected to the signal processing / control module, a receiving module, a number / information input module, a display module, an identity authentication module and an external data interface module, so its structure It is not possible to effectively and fully reduce the size and weight; the battery must provide power for these modules, so the power consumption is still very large, and a battery with a certain power reserve cannot provide a longer standby time; especially with the multi-functional development of mobile phones Generally, it is combined with PDA personal digital assistant, and PDA module is hung on the signal processing / control module, resulting in the increase of electronic modules and peripheral equipment of the host, that is, the handheld unit, and the volume is becoming larger and heavier. Although it has certain word processing functions, such as electronic business cards, meeting schedules, etc., it brings inconvenience to the user's mobile phone use and reduces the flexibility and lightness of the mobile phone's main purpose; finally, its handheld unit and radio frequency unit It can only be used together. The pure radio frequency unit does not have a transmitting module, a receiving module and a signal processing / control component, and cannot be used for talking. It must also have a transmitting module, a receiving module and a signal processing / control component. Structural design will cause repeated setting of hardware, and the information terminal combined with mobile phone and PDA personal digital assistant can also be provided with microphone, microphone or earphone parts on the man-machine interface of PDA module, so that the information terminal has call capability, so mobile While the phone adopts a split structure, it is considered to be combined with a PDA personal digital assistant, so that both the handset unit and the host unit can be used for conversation, to achieve the mother-child machine function and personal digital processing function, together with application programs and operating systems, to Make full use of existing electronic modules and hardware to achieve multi-function, low cost, high performance / price ratio
