Description

A mobile communication system and method based on instant messaging

technical field

The invention relates to electric communication technology, in particular to a mobile communication system and method based on instant messaging.

Background technique

With the development of society and technology, people pay more and more attention to the timeliness of information exchange and communication. Therefore, various communication technologies that can make people's mutual contact and communication more and more convenient are gradually recognized and accepted by users. For example, mobile communication terminals have become an important communication tool for many people, bringing convenience to people's work, life and study. However, there are some deficiencies in existing mobile communication systems:

First of all, the traditional mobile communication network needs to establish a unified base station, and the investment is relatively huge, which makes it impossible to popularize in many economically underdeveloped areas and hinders the popularization and application of mobile communication technology.

Secondly, because the base stations of the mobile communication network are uniformly established by the operators, due to the consideration of various practical situations, there are a large number of signal blind spots in high-rise buildings, mountainous areas and wild areas, which cannot better meet people's communication needs.

Again, the high call charges of mobile communication are not a small economic burden for ordinary consumers, and the price of mobile communication terminals is also a considerable expense for many consumers.

In addition, in daily life, people often use instant messaging technology and wireless intercom technology to exchange information.

The principle of instant messaging technology is to realize point-to-point real-time information transmission through the Internet, including files, text, images, voice, video and other information. As a way to instantly communicate with others through the Internet, instant messaging systems have the characteristics of strong interaction and low price, so instant messaging systems can be popularized in a short period of time.

However, the existing instant messaging technology can only realize wired communication on the Internet by means of computers, and cannot directly satisfy users with mobile communication needs.

The use of wireless intercom technology can enable point-to-point information transmission between two mobile communication terminals within a limited distance range, and the mobile communication terminal can directly send and receive signals. Within a limited distance, free communication can be realized, regardless of the venue. Restrictions, do not pay phone bills.

However, there are also some shortcomings in the use of wireless intercom technology: First, only a small range of communication is carried out within a limited distance, and the two parties in the communication must agree in advance that the distance between the two parties should not be too far. Secondly, walkie-talkies generally have 10-20 call channels, as long as they are on the same channel, they can talk to each other, no matter how many, but the call channels need to be negotiated and set manually, which is inconvenient to use. Again, if there is no negotiation, one party switches the channel and the other party does not switch, then the normal conversation cannot continue.

Please refer to FIG. 3 , on the basis of the aforementioned mobile communication system, the flow of the instant messaging-based mobile communication method of the present invention is as follows.

In step S1, when the wireless communication terminal is turned on, the instant messaging client automatically registers, including recording its area and channel, assigning an identifier to it, and so on. The identifier is unique to each wireless communication terminal, and may be an ID number, a user name, and the like.

Step S2, when a certain user needs to contact other users, use the wireless communication terminal to send a call request including the called ID to the instant messaging client through the wireless communication interface. It can be understood that the sending of the call request can be performed by using various existing wireless signal sending methods, and is not limited to a specific method.

Step S3, the instant messaging client parses the aforementioned call request, and searches for the called wireless communication terminal according to the called identifier. Since all wireless communication terminals are automatically registered through the corresponding instant messaging client when they are turned on, the search is similar to the search for existing instant messaging users.

Step S4, after finding the called wireless communication terminal, make a call. According to the different regions of the calling parties, there are two ways to call: one is that the instant messaging client sends a call request to the instant messaging server; the instant messaging server sends a call message to the called instant messaging client; the instant messaging After successfully calling the called wireless communication terminal, the client sends a response message to the instant messaging server. The other is that when both calling parties are within the range of the same instant messaging client, the instant messaging client directly calls the called wireless communication terminal.

Step S5, after the called party answers, establish a call channel between the wireless communication terminals based on the instant messaging technology; the wireless communication terminals transmit data signals to each other through the instant messaging terminal using the TCP/IP protocol and the UDP protocol of the instant messaging to realize mobile communication . The data signal includes text, image, voice or video information and the like.

In addition, during the mobile communication process, the wireless communication interface monitors the communication quality, and adjusts the frequency of the wireless communication terminal in real time according to the communication quality.

In order to facilitate the understanding of the present invention, the present invention will be further described below in conjunction with the examples.

Please refer to Fig. 4, in the present embodiment, the wireless communication interface 120 realizes the wireless mobile communication from the wireless communication terminal 110 to the instant messaging client 130, and realizes real-time communication between two remote instant messaging clients 130 through an instant messaging tool, so that the two The wireless communication terminal 110 indirectly realizes the wireless mobile communication function not limited by the distance.

The wireless communication terminal 110 selects a walkie-talkie, and transplants part of the operation functions of the instant messaging tool on the walkie-talkie. That is to say, the wireless communication terminal 110 includes an intercom part (not shown in the figure) and an instant messaging control part.

The intercom part includes a transmitting module, a receiving module, a modulating module, a modulating circuit and a signaling processing module.

The instant messaging control part is used to increase the control function of the instant messaging tool in the existing walkie-talkie, thereby controlling the communication between the intercom part and the instant messaging client 130, and realizing the operation of the instant messaging tool, such as adding To call someone, to establish a communication link with someone, etc.

As we all know, the maximum communication range of walkie-talkies currently on the market can exceed 10 kilometers, and there is no additional cost for use except for machine charging. It is a common communication tool for many field workers and mobile operators. Because as long as there is the Internet, users can chat freely around the world through instant messaging tools. Therefore, in the embodiment of the present invention, the operating functions of part of the instant messaging tool are transplanted on the walkie-talkie, and the walkie-talkie is combined with the instant messaging software, which can partially replace the current mobile phone.

The instant messaging client 130 can adopt various electronic devices with data processing capabilities, and set instant messaging tools therein. In this embodiment, a computer is used.

The wireless communication interface 120 is a wireless intercom transceiver unit, and the wireless transceiver unit is set on a computer serving as the instant messaging client 130 . The specific method is: change the wired earphone microphone connected to the computer into a wireless connection mode, transform the original earphone microphone into a wireless intercom transceiver unit, and control the function buttons of the earphone microphone on the computer, such as volume switch and some instant messaging. The operation function buttons of the tool are transplanted to the walkie-talkie, so that the walkie-talkie can be connected to the computer wirelessly, replacing the original earphone microphone of the computer to communicate with other people through the network, and at the same time can control the communication between the walkie-talkie and the computer. The original wired transmission signal is Turning into wireless transmission, the wireless intercom transceiver unit plays the role of communication between the walkie-talkie and the computer, and is responsible for the sending and receiving of signals. In this way, two walkie-talkies in any part of the world can talk freely.

The signal is divided into two types, one is the user's communication signal, that is, the text and voice information that the user wants to send or receive, and the other is the control information, that is, the information sent by the walkie-talkie to control the computer function, that is, the instant messaging software. operation, add a call partner, establish a communication link with someone, etc.

The mobile communication method of the embodiment of the present invention is introduced below.

First, use the instant messaging client (computer) to automatically adjust the wireless communication terminal to be communicated (the walkie-talkie that integrates part of the instant messaging operation function), and assign a unique identification number, such as an ID number, to each walkie-talkie. When the walkie-talkie is turned on, it automatically Register with the instant messaging system on the same frequency band. Thereby it has a positive effect compared with the prior art, because when using an ordinary walkie-talkie, the user must make an agreement in advance and both parties must manually adjust the walkie-talkie to the same channel to realize the conversation.

The specific registration process is similar to the traditional mobile phone registration. When it is turned on, it will automatically search for the network, and the walkie-talkie will send a connection signal to the surrounding environment. Enter the ID number of the walkie-talkie, so that the walkie-talkie will log into the instant messaging system, which is equivalent to an instant messaging user going online. The instant messaging system records the region and channel of the walkie-talkie.

When a walkie-talkie user wants to communicate with a user in another area, the walkie-talkie sends a request to the local instant messaging system, and the walkie-talkie provides the ID number of the other party to be communicated to the instant messaging system, which is equivalent to sending a chat request to his instant messaging friends .

The instant messaging system finds the registered target user and makes a call, and the two users communicate through the instant messaging system.

Wherein, the specific search process is that the instant messaging client searches for the called wireless communication terminal according to the ID number. Its implementation is similar to the chat system of existing instant messaging. Since each instant messaging user logs in, the server will record its online IP address, so through the unique IP address, search and communication can be realized between various instant messaging users.

Concrete call can have two ways according to the difference of the regions where both parties are in the call: one is that the instant messaging client sends a call request to the instant messaging server; the instant messaging server sends a call message to the called instant messaging client; After successfully calling the called wireless communication terminal, the communication client sends a response message to the instant messaging server. The other is that when both calling parties are within the range of the same instant messaging client, the instant messaging client directly calls the called wireless communication terminal; of course, at this time, the wireless pairing technology can also be used to directly communicate.

After the called party answers, a call channel between wireless communication terminals is established based on instant messaging technology; wireless communication terminals transmit data signals to each other through instant messaging terminals using instant messaging TCP/IP protocol and UDP protocol to realize mobile communication. The data signal includes text, image, voice or video information and the like.

During the communication process, if the voice quality is not high, the system will automatically adjust the frequencies of both parties: the wireless intercom transceiver unit detects the frequencies of the two walkie-talkies and adjusts them so that the two frequencies tend to be consistent and achieve a clearer voice effect. That is to say, with the participation of the instant messaging system, communication channels can be subdivided to support more mobile terminals for communication.

The above description is only a preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications are also It should be regarded as the protection scope of the present invention.
