System and method for expanding mobile communication function of portable terminal electronic equipment

Abstract

The invention provides a system and a method for expanding a mobile communication function of portable terminal electronic equipment. The system provided by the invention consists of first expansion equipment, second expansion equipment and the portable terminal electronic equipment; the portable terminal electronic equipment is connected with the first expansion equipment in a WIFI (Wireless Fidelity) manner; the second expansion equipment is connected with the first expansion equipment in a Bluetooth manner; the first expansion equipment is connected with a mobile communication wireless network through a communication module I; and the functions of mobile communication, short message receiving and sending, and mobile networking of the portable terminal electronic equipment can be realized by virtue of the entire system. The system and the method provided by the invention have the advantages as follows: the portable terminal electronic equipment with a WIFI function can carry out the mobile communication anytime and anywhere, send and receive short messages and get on an internet in a mobile manner; a method for controlling a low-power-consumption state and a normal working state of the expansion system by a user side according to demand can be realized, so that the problem of large power consumption is solved, and a standby state with lower power consumption and longer time can be realized.

Description

technical field [0001] The invention relates to a system and method for expanding mobile communication functions of portable terminal electronic equipment. Background technique [0002] Portable terminal electronic devices such as Apple's iPad and iPod touch, tablet computers, netbooks, and notebook computers are becoming more and more popular. These portable terminal electronic devices already have WIFI wireless Internet access functions, but there are the following problems: [0003] Question 1: You can only surf the Internet wirelessly in places with WIFI networks, but many places do not have WIFI network coverage, so you cannot surf the Internet anytime, anywhere, and there is a problem with WIFI network roaming. In the case of fast movement, you need to switch WIFI access points , will drop the network; [0004] Problem 2: The above-mentioned portable terminal electronic devices do not have the functions of mobile calling and short messages. [0005] In order to solve...

AI Technical Summary

Problems solved by technology

[0003] Question 1: You can only surf the Internet wirelessly in places with WIFI networks, but many places do not have WIFI network coverage, so you cannot surf the Internet anytime, anywhere, and there is a problem with WIFI network roaming. In the case of fast movement, you need to switch WIFI access points , will drop the network;

[0004] Question 2: The above-mentioned portable terminal electronic devices do not have the functions of mobile calls and text messages

[0005] In order to solve the above problem 1: 3G-WIFI wireless routers have appeared on the market. The existing 3G-WIFI wireless routers must maintain a certain working state when the user is not online so that the user can access at any time. There is a shortcoming of large power consumption, or You must manually turn on and off the 3G-WIFI wireless router every time, and there is no mobile call function

[0006] 1. The power mode of the WIFI module must be manually changed through the web interface and the router needs to be restarted. This is a simple switching of the transmission power, and no matter switching to any working mode, a certain working state must be maintained so that the user can Access at any time, there is a disadvantage of high power consumption;

[0007] 2. The invention patent application does not have the functions of mobile calls and text messages

[0008] In order to solve the above problem 2: the utility model patent application number is 201120016734.0, and the patent application titled "3G-WIFI portable router with WIFI voice function" proposes a device for transmitting voice signals through WIFI. Yes:

[0009] 1. The utility model patent does not provide a solution to WIFI voice transmission. The disadvantage of WIFI voice transmission is that it is usually based on IP, which is very sensitive to transmission delay and signal jitter, and it is difficult to guarantee the quality of voice transmission;

[0010] 2. This utility model patent also has the problem of high power consumption. Since the router and WIFI terminal must be able to respond to incoming calls and make calls in real time, the router and WIFI terminal must always be connected, and the power consumption is too large, causing the router and WIFI The standby time of the terminal is very short, usually only a few hours, which cannot meet the standby requirements of mobile communications;

[0011] 3. The problem with this utility model patent is that it cannot support WIFI terminals without voice input and output device microphones and speakers, because the utility model patent requires that WIFI terminals must have voice input and output device microphones and speakers in order to realize voice calls
