Cell phone apparatus capable of replacing different network formats and implementation method thereof

Abstract

The invention provides a cell phone apparatus capable of replacing different network formats and an implementation method thereof. The cell phone apparatus comprises a cell phone body main board circuit and a modularized wireless processing module with different network formats, wherein the cell phone body main board circuit is provided with a slot with a predetermined interface, the modularized wireless processing module with different network formats is provided with a pin for the predetermined interface; when certain network format is adopted, the pin of the modularized wireless processing module with the network format is plugged into the slot of the cell phone body main board circuit, and the main board circuit and the modularized wireless processing module implement mutual communication via the predetermined interface, when the replacement for network format is required, the pin of the modularized wireless processing module with other corresponding network formats is plugged into the slot of the predetermined interface of the cell phone body main board circuit. The cell phone equipment can achieve the function that users are capable of simply, conveniently and rapidly replacing different network formats on their own, and lower the cell phone design cost of factory and the network change cost of user.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, the present invention relates to a mobile phone device capable of changing different network standards and an implementation method. Background technique [0002] With the continuous advancement of science and technology, the volume of mobile phones continues to shrink, and they are now very popular. With the rapid development of mobile networks, from the Global System for Mobile Communications (GSM, Global System for Mobile Communications) of the 2G network, Code Division Multiple Access ( CDMA, Code Division Multiple Access), CDMA2000, CDMA20001X network to 3G wideband code division multiple access WCDMA, wideband code division multiple access high speed packet access WCDMA HSPA, CDMA1X EVDO, CDMA1XEVDV, TD-SCDMA, PHS, WiMax and future 4G LTE . Many mobile phones are designed with a closed architecture, resulting in a mobile phone that only supports one net...

Problems solved by technology

Many mobile phones are designed with a closed architecture, resulting in a mobile phone that only supports one network standard. Consumers can only choose a unique network standard mobile phone to use when purchasing a mobile phone. It is very inconvenient to change the mobile phone or carry two mobile phones at the same time, and it is necessary to pay for the purchase of a mobile phone. network, not only have to pay more for a GSM mobile phone, if the replaced CDMA mobile phone is not reused, it will be regarded as a kind of electronic waste and eliminated. Mobile phones generate such a huge amount of electronic waste, which wastes a lot of earth resources and has an impact on the environment

[0003] At present, the industry has also developed mobile phones that support two network modes, such as the current dual network dual standby, C+G (CDMA+GSM), P+G (PHS+GSM), T+G (TDSCDMA+GSM), P +C (PHS+CDMA) and other dual-mode mobile phones, but due to the closed structure, not only the price is high, but also the volume is generally large, the standby time is short, and it can only support the specified two standards. , cannot fully work under the diversified global network standards. For example, the network standards in China include GSM, CDMA20001X, WCDMA, CDMA1X EVDO, TD-SCDMA, the network standards in Japan and South Korea include PHS, WCDMA, and CDMA1X EVDO, and the network standards in Europe include GSM, WCDMA, HSDPA, North American network standards include CDMA20001X, CDMA1X EVDO, HSDPA, and future 4GLTE networks. The diversification of the global standards will increase and expand infinitely, so that these dual-mode mobile phones cannot be fully compatible. Or compatible with the upgraded standard of the future mobile network

This will cause certain models of mobile phones of different brands of mobile phone manufacturers to be sold only for a certain country, and to sell to other countries requires redesigning the entire machine circuit, and such development and design costs are huge, not every manufacturer has What can be easily achieved by strength often causes a delay in the global launch of a new mobile phone, and even some countries cannot launch it at all. Usually, the R&D cost of a new mobile phone will account for 30% to 50% of the retail price of the mobile phone. , and the huge research and development costs caused by this will be apportioned to consumers, which will make the cost of mobile phones high. The reason for this is the problem of incompatibility caused by the different network standards of countries around the world
