Abstract

It is possible to transmit information by applying Wifi Direct, which can be connected without any characteristics of all terminals, and to limit the number of conventional connections with the corresponding technology. In addition, due to the restriction of the wireless space, there are disadvantages in that it is difficult to transmit and share due to the restriction on the operation of a large capacity file. To overcome these drawbacks, it is necessary to transfer and share large files using commonly used Short Message Messenger.
The Wifi Direct connecter restriction establishes a group through the server communication and enables the restriction of the number of the connection through the connection between each group. For large files, UDP punching can overcome the drawbacks of wireless space constraints.
Conventional short-range communication method In the case of Bluetooth or NFC, continuous execution has caused resource shortage or battery shortage in the terminal. In the case of Wifi Direct, it compensates the corresponding part and dramatically increased the distance between the transmitter and receiver. However, there are limitations in the number of concurrent connections. Due to the development, it is expected that the constraints of simultaneous implementation will be solved and this part will be greatly utilized in general store marketing.
Short Message Messenger is currently used by everyone, and if you can not use the Messenger, it will be widely used to hinder your daily life. However, due to the limit of the transmission capacity of the Messenger, it is troublesome to open and send mail. So, we developed Messenger to send and receive large files. We expect that the development will eliminate the hassle and increase the efficiency.

Description

How to transfer large files using SmartPhone Messenger and how to transfer large files using Wifi Direct technology. How to transfer large files using smartphone messenger and transfer large files using Wifi Direct.

An object of the present invention is to transmit and provide a large-capacity file to other users in the same group using SmartPhone Messenger. The present invention also relates to a system capable of sharing transmitted files between Android and IOS terminals by applying Wifi Direct technology to each other.

Android or IOS terminals are connected with peripheral service user terminals using Wifi Direct technology, and a specific terminal operator distributes information and transmits information of the terminal.

With the development of mobile communication technology and the popularization of mobile communication terminals, mobile terminals such as smart phones, tablet PCs, and PDAs have replaced the role of personal computers in the past. In particular, all communication between mobile terminals is aimed at a wireless system in order to overcome interface restriction of mobile terminal and to guarantee mobility. However, the Wifi network process according to the related art is complicated and troublesome, and has a disadvantage that the user is required to have prior knowledge of the wireless network. Therefore, it is possible to transmit all information by applying Wifi Direct, which can be connected without distinguishing all terminals. In addition, due to the limitation of space in Wifi space, there is a limitation in transferring large capacity files due to restriction of downloading. To compensate for these shortcomings, we made it easy to communicate and share large files using the short text messenger.

[3] Implementation of Real-Time Video Transmission System Using Wi-Fi Direct (Wi-Fi Direct)

In Wifi Direct technology, the connection between the information transmitting device and the information receiving device is indispensable, and the process must always be in preparation for Wifi Direct. This problem can lead to inefficient use of resources, unnecessary battery consumption, and the use of more data than is required by the user, resulting in poor usability. In addition, Wifi Direct is disadvantageous as one-to-many information transmission medium because there is a factor that only a maximum of 7 users can be connected simultaneously in one to many connections.

The present invention provides a method and apparatus for increasing the efficiency of a device providing an application service based on Wifi Direct and increasing the number of users' media for service use.

As a means of solving the problem, the media providing Wifi Direct is operated in real time, and the role of the media player is charged to the general users in the inside, thereby minimizing the battery and process units consumed in real time, So that they can be notified when they approach.

Based on the user's location, download the designated area of the Wifi Direct from the Server and enable the Wifi Direct Service to be driven through the call of the MQTT server.

Also, in case of 7 users per single device, all Wifi Direct delivery media will look at the Relay Server and if it is recognized as Wifi Direct connection in the same network according to user's connection, Service Server .

According to the present invention, since the device providing the application service based on Wifi Direct performs the same service as the general media player device, no additional power consumption is required for Wifi Direct, and other devices provided outside the service are also called Wifi When accessing the direct area, automatic service search is performed, so that the connection effect can be seen without any separate consuming action.

In addition, because it restricts the very limited part of the previous connection through the Relay Server, it can make infinite Wifi Direct connection and it can give satisfactory results to both users of information providing subject and information.

.

Figure 1 shows the software configuration of the basic Wifi Direct technology.
2 shows a drawing of the device connected in FIG.
3 shows a software configuration for sharing a large-capacity file that is served in FIG.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an apparatus and an operation method of the present invention will be described with reference to the accompanying drawings. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

Figure 1 illustrates the service client configuration and service group configuration using Wifi Direct. In the present invention, the Wifi Direct Client 7 User can be infinitely increased by the capacity of the Server 230 service in the process of forming the entity of the Group 120, and the Service Group can also be increased through the Group Service 240 . Accordingly, the clients of each group connected by the Wifi Direct Machine (220) can be identified as the same whole group or each individual group, and the same service or individual service can be granted from the Wifi Direct Machine (220).

Figure 2 is the daily internal view of the Wifi Direct device. Has at least one Lan Cable Port (410), and can use the wireless (540). It has USB (440,430) port that can be connected to external devices. It has a local memory (530) for interworking with external devices and setting the development program.

The third diagram shows file sharing using the Wifi Direct Machine (220). Group or 1: 1 messenger communication, it is possible to import the file from the mass storage device connected to Wifi Direct Machine (220) or Network (Internet or Intranet) through the communication with the server and express it in the current Messenger chat room. It uses UDP punching, which is different from Media Streaming, which was previously transmitted through Wifi direct method or Media streaming method, which was connected to Internet. And only the list can be outputted through the file list server 250 when only the corresponding file is shared.

Using Wifi Direct, event information and discount information of the store are provided to the user who has the corresponding development application by SmartPhone.

Wifi Direct information transmission device Since the transmission method is within the radius, user convenience can be achieved.

The contents of the space and resource constraints of the large file can be solved by the large-capacity file transfer between the messenger of the corresponding development. Mass transfer and sharing function installed in Messenger enables you to open files installed at home or at the company from anywhere and share with friends.
