Summary of the invention

The purpose of this invention is to provide a kind of internet that utilizes and between mobile communication equipment, realize the method that timely message transmits.

For achieving the above object, the present invention adopts following technical scheme:

Of the present inventionly send the method for timely message, comprise the steps: with mobile device

A) by internet protocol message server and subscriber equipment are connected on the internet, and keep connecting;

B) subscriber equipment sends a message to message server;

C) after message server receives message, earlier data volume is carried out verification, impaired as data, then require subscriber equipment to transmit again; The data of server reception are resolved then, take out the target of message respectively, the identity information of content and transmit leg; After the identity of acknowledged, message server is sought the targets of messages user at registered user's lane database, if find back current goal user to keep being connected with server owing to shutdown or other reason, server with message stores at database, otherwise just, send to the targeted customer immediately according to the client address that connects.

In step b), after subscriber equipment sent a message to message server, message server sent " OK " message to the subscriber equipment that sends message, if this subscriber equipment is not received " OK " message in special time period, then repeated to send.

In step c), after the targeted customer receives message, send " OK " message to message server, if message server is not received " OK " message in certain period of time, then repeat to send.

Above-mentioned subscriber equipment and targeted customer, one of them is a mobile communication equipment at least, is connected with internet by CDMA or GPRS agreement.

After adopting technique scheme, have following advantage:

1, reduce the mobile communication expense:

Because system adopts the communication modes of GPRS or CDMA, the business model of utilizing its always online technical characteristic and charging by flow can be saved cost of use greatly.Compare with traditional short message communication mode, because short message is to collect the charges according to sending number of times, and the timely message system of mobile phone need not paid when each reception or transmission message, only needs expense and a spot of ISP of payment certain communication flow.Just can send and accept every timely message that then reaches 512 characters

2, realize cross-platform information interchange:

Because the portable terminal of native system is by GPRS or CDMA mode access internet server, get in touch each information terminal by the internet, so can break through restriction, no matter be that mobile phone or computer can be by native system and other middle end communications to the terminal hardware platform

3, voice and video communication:

If the hardware and software platform support of network traffics and user's portable terminal uses native system can also realize the multi-media communication of the voice and video between each terminal.

4, multileaving:

Support the function of similar traditional short-message cluster-sending, only need once to send, can be sent to a plurality of terminals.And the expense that sends and receive generation is cheap.

5, realize portable terminal and computer alternately and combine:

Mobile phone users in the system can directly send message by the Internet to other-end with computer, also can receive the message of other-end, reaches the function of wireless terminal expansion.

6, cross-region message transmission expense is cheap:

Mobile phone users sends and receives timely message to the user of other region, and expense equates with local, not limited by the region.

The basic function that this method can be achieved as follows:

1, send message can for other portable terminal or computer

2, can receive the message of other portable terminal or computer

3, portable terminal can automatic reception message, and adopt multiple mode to remind the user at once

4, can carry out the communication of voice and video

5, can send traditional short message to other user who does not open GPRS and CDMA.

6, multiple spot sends, and can send same message simultaneously to a plurality of users.

Description of drawings

Accompanying drawing is the transmission principle schematic diagram of the timely message of one embodiment of the present of invention in physical layer.

Embodiment

As shown in drawings, in the use of message system, cellphone subscriber 2 client software uses Socket sockets interface standard earlier, log on message server by IP network, and keep the TCP of IP layer to be connected with server, and perhaps connect expense for saving, also can set up the UDP connection.So just can carry out the timely both-way communication of mobile phone and server 1.

When the cellphone subscriber has message need be when other user or group send, mobile phone client software can be with the information of the target of message and content and this machine with the set form package, and adds check code, prevents that message from producing error code in transmission.Send in the past by the data of IP network to message server then packing.

After server 1 receives data, earlier data volume is carried out verification, impaired as data, can require client to transmit again.Server is resolved the data of packing then, takes out the target of message respectively, the identity information of content and transmit leg.After the identity of acknowledged, server can be sought the targets of messages user at registered user's lane database, if find back current goal user to keep being connected with server owing to shutdown or other reason, server 1 with message stores at database 3, otherwise just, send to the targeted customer immediately according to the IP address of the client that connects.

, also needing message is encapsulated at server 1 before cell-phone customer terminal sends timely message, at first is the identify label of transmit leg, message content, and check code.Client is carried out verification with all after receiving message, bag is resolved, and extracts message content.

Because system is based upon on the IP application layer, thus need wireless device to realize the IP agreement, and certain interface mode is provided, as Socket socket or the like.In time message is in the transmission of physical layer.

To the encryption of the content of timely message, can adopt the encryption method of multiple suitable wireless device computing capability, verification mode also can suitably be removed according to the different of encryption method.

It below is the simple data group packet mode of transmission of messages.

The present invention has opened the mobile phone of data service and wireless PDA and custom-designed timely message service system at novel with GPRS or CDMA form.This system is included in the client software that moves on the mobile phone and moves the messenger service client software of (as PC) on computers, and the timely message server that timely messenger service is provided.

In time messenger service has very big difference with traditional SMS service in the technology realization, traditional Short Message Service at first will send a message to the SMS gateway, be submitted to message center again, be distributed to each wireless base station, then the mobile phone that sends by the base station by message center.When transmission of messages, route is clear and definite, can be included into the real circuit switching technology substantially.And in timely message service system, mobile phone client software is by the Internet access technology of GPRS or CDMA, and the timely message server that visit is erected at Internet directly reads and send message, realizes the communication with other mobile phones and computer.

If the timely message server among the present invention is an example with the Java development platform, can be divided into the WEB server, three parts of OTA server and message central server.Also can merge on this basis, perhaps delete unwanted part as the case may be.

WEB server wherein is to be used for realizing that the cellphone subscriber sends and receive the function of timely message by the standard I nternet browser of computer terminal, can also provide secure registration in addition, helps, and downloads the service function of cell phone software.Server can adopt Php, Perl, and multiple suitable tool software such as J2ee is made the dynamic script service routine, starts the WEB service then, carries out for the browser downloads of computer terminal.When browser end sent or receives timely message, the database of WEB server access message central server read or adds timely message, sends and receive message by message central server.Because these technology are comparative maturity at present, method for designing is varied, does not do at this and gives unnecessary details.Concrete transfer of data and the RFC document of other design standard referring to relevant http.

The OTA server provides to the service of Java mobile phone by GPRS or CDMA visit, comprises mobile telephone registration, the functions such as issue of mobile phone client software MIDlet program.For the situation that does not adopt the Java platform development, can delete the OTA server or reduce its function.Server can adopt XML or other instrument and grammer that is suitable for to write, and mobile phone or other wireless device can be by the MIDlet programs of built-in browser downloads client.By embedding the method for JSP/Servlet plug-in unit, Servlet can be used for finishing the registration and unregistration of mobile phone, and guarantees password and other useful information transmission safety on the networking.In the user record of message central server database, add the deletion user record then.

Message central server is the core of whole system, and all basic functions all realize by central server.Server is according to the data communication principle of TCP/IP, can adopt the Design Mode of client/server, carry out the TCP communication with client software such as mobile phone, directly send the purpose of timely message thereby reach the transfer of timely message or assist client to connect.The implementation method of server is many, and the instrument that is adopted is relatively variation also, according to basic function provided by the present invention, the implementation of following simple possible is arranged.

At first, central server is responsible for cellphone subscriber's data management, the personalized setting.Client softwares such as mobile phone can be registered to message center in several ways, and central server adds the data that client provides in the database to.When message status changes, as receive new message or need transmission message, server will be revised these records, mark timely condition of information.

Message sink and send and can adopt message queue or other feasible modes to manage needs to send when client has new message, and server judges according to the destination whether the recipient opens GPRS or CDMA, otherwise just sends according to the mode of traditional short message.If the purpose mobile phone has been registered in the database of central server, server adds message to message queue.The processing messages formation that central server can not stop with thread, when message need send, server was judged type of message earlier, sends Multimedia Message if desired, just received annex earlier and preserved.If the purpose mobile phone is not online, just message is backed up, when next user lands, send, otherwise order sends one by one.

The design of the communication aspect of server need connect the method for designing of Server with reference to TCP, and at the tissue of data, the management aspect according to circumstances method for designing in comparable data storehouse is developed, and the main flow process of software is referring to the flow chart of server.

Operate in the client software on mobile phone or other wireless device, can adopt Java to write, download by OTA and carry out.Also can do special design at the operating system of various mobile phones.Consider the hardware and software development of mobile phone from now on, client also can adopt other some methods that are suitable for exploitations, as is directly fixed in the mobile phone, or adopts method such as BREW development platform.

When the user has been registered to the server database of message center, when client logs on central server by the TCP ways of connecting at every turn, all need checking by server.By reading message status earlier after the checking, if new message is arranged, just begin to receive message, and can show and listen to Multimedia Message.After reading, message can be trapped in server, as backup information.When the user need send timely message, earlier message is sent to central server, be forwarding by server generation.

After user end to server sent the multimedia connection requests, server can assist it to be directly connected to destination address, perhaps passes through transit server.The computing capability of considering present mobile phone and other wireless device is limited, and server can assist it that unpressed image or sound are compressed into the form that is fit to GPRS or CDMA bandwidth permission transmission, is distributed to other destination address again.

The main flow chart of the client software design on the wireless device can be referring to subsidiary client software flow chart, and the client software communication need connect the method for designing of Client with reference to TCP.

When message transmission in time, because major part is to transmit on Internet, message body should not be adopted clear-text way, divulges a secret otherwise be easy to generate, so can adopt certain cipher mode, needs to keep the synchronous of encrypting and decrypting simultaneously.In the process of client game server, can adopt the mode of SSL or RSA to carry out authentication.To keep the safety of system.

Though the above combines software flow pattern and is illustrated, the invention is not restricted to this, this literary composition mainly is to be example with the Java platform, its implementation is carried out feasibility describe, the concrete right protection range can change in the claim scope.
