Background technique
Communication refers to the information interchange and transmitting carried out between person to person or man and nature by certain behavior or medium, from
Referring broadly to the both sides for needing information or in many ways without prejudice to respective wish using any means, any medium will
Information is accurately safely transmitted to another side from certain side.
Communication has different explanations in different environments, communicates after there is Potential transmission communication
(Communication) by the single transmitting for being construed to information, refer to from one to carry out anotherly the transmission of information with exchange,
The purpose is to transmit message.However, communication is in human practice process as the development of social productive forces is to transmitting message
It is required that constantly being promoted so that human civilization is constantly progressive.In various communication modes, message is transmitted using " electricity "
Communication means is known as telecommunications (Telecommunication), this communication have the characteristics that it is rapid, accurate, reliable, and hardly
It is limited by time, place, space, distance, thus is developed rapidly and be widely applied；Now because of the agility of electric wave
So that the material object for just cultural exchanges being combined constantly to accumulate progress with real economy from Ancient people material exchange process communicates
(postal & communications) are the obstruction for restricting economic development by human intelligible.
Summary of the invention
The object of the present invention is to provide a kind of instant network switching method, this method includes being switched using a kind of instant network
System carries out instant handover network, and the instant network switching system includes: network switch, is located in smart phone,
