Abstract
A novel P2P communication terminal (6) based on IPv6 Internet technology. A communicating system composed of the communication terminal (6) do not need any control and management equipment. Number distribution and the management of communication can be self-completed by the communication terminal (6).
Description
Affiliated technical field
The present invention relates to a kind of novel communication terminal (6) based on IPv6 (Internet Protocol Version 6) Internet technology.
Background technology
Mainly be based on the landline telephone and the mobile phone communication system of circuit exchange mode at present in the communications field, its communication system is to be controlled and managed by central equipment.Its advantage is: the communication line special use, and data are through, and propagation delay time is little, and is real-time, and data transmit in proper order, do not have out-of-sequence problem, both have been applicable to transmission of analogue signal, also are applicable to transmission of digital signals, and switching equipment and control are simpler.Shortcoming is: long slightly for data communication average connection setup time, physical circuit is monopolized, and channel utilization is low, and the terminal of dissimilar, different size, different rates is difficult to intercom mutually and carry out error control.For service layer, based on Circuit-switched communication system, can't adapt to the network and the service synchronization development of each communication common carrier in the global range, various Added Business are the multimedia service slower development especially, and miscellaneous service is difficult to merge, and is difficult to realize trans-regional and transnational free roaming.Another shortcoming is that communication cost is difficult to reduce, especially the roaming communication expense.
Along with Internet development, the communication pattern based on the Internet has appearred, and internet communication belongs to a kind of of packet-switch technology, also cries packet switch.The transmission means that packet switching adopts storage to transmit, its advantage is: the channel utilization height, need not special circuit, no connection set-up delay allows Route Selection, can avoid the fault route, improve transmission reliability, be convenient to communicating by letter of polytype, specification and speed, can multicast, multicast etc., allow priority.Its shortcoming is: exist and transmit time delay.In general, packet switching is better than the data communication of circuit exchange mode.The communication of the Internet has manifested its advantage gradually based on IPv4 (Internet Protocol Version 4), can realize the mail in the global range, instant message, voice, communications such as video, or IP (Internet Protocol) phone of the low telephone expenses that provide by each communication common carrier communicates.Voice communication based on the IPv4 the Internet at present mainly contains following four kinds.
First kind is Phone to Phone, sees Fig. 1, and this class phone (1) depends on the SPC telephone exchange (2) and the IP phone gateway (3) at two ends.The Internet is only as the transmission channel between the gateway (3).The Phone here (1) is ordinary fixed or mobile phone.
Second kind is PC (Personal Computer) to Phone, sees Fig. 2, and this class phone depends on the SPC telephone exchange (2) and the IP phone gateway (3) of plain old telephone (1) one end.The Internet is as the transmission channel between PC (4) and the gateway (3).This mode generally can only uni-directional call.
The third is PC to PC, sees Fig. 3, and this class communication depends on the equipment such as third-party server (7) on the Internet usually, carries out voice communication by the JICQ on the PC, webpage control etc.Concerning the individual, because the IP address is fixing and NAT (Network Address Translation) to the restriction of outer net incoming call, be difficult to carry out direct communication between PC and the PC based on the Internet, unless fixed IP addresses is arranged, and also to do port mapping mostly, do unrealistic also not convenient like this.So this communication all is based on the equipment such as third-party server (7) on the Internet usually.
The 4th kind is IP Phone to IP Phone, sees Fig. 4, and this class phone is normally as the enterprises telephone system, and range of application is very limited.Though be pure IP phone, the management of system and control still be unable to do without equipment (8) such as server, router.Even can finish the communication of crossing internet, but the Internet is usually only as the transmission channel between the internal lan.
Though internet communication has a lot of advantages,, cause a large amount of uses of NAT device on the network because the IPv4 address resource is seriously in short supply.Generally, NAT device can stop the outside calling of initiating, and this has just caused a lot of application to realize, especially the personal communication of P2P (Pear to Pear, peer-to-peer network) mode.Along with the Internet from now on from IPv4 to the IPv6 transition, the address no longer becomes scarce resource, the Internet can become the real network that freely interconnects.
Summary of the invention
Realize that at present existing various types of communication system is very difficult individual in the global range is to individual interconnecting arbitrarily, and existing communication relies on the support of third party device mostly, and communication expense is crossed high shortcoming, the present invention proposes a kind of novel communication terminal based on the IPv6 Internet technology (6).Here it is the 5th kind of internet communication, this communication mode is very brief on network configuration, in order to be different from the 4th kind, is its New IP Phone to New IP Phone for the time being, sees figure-5.This communication mode is different from preceding four kinds of internet communications of using fully on IPv4.
Technical scheme of the present invention is: on the internet, between the communication terminal (6), and the communication between communication terminal (6) and the miscellaneous equipment do not need third party device fully, do not need the number assignment and the conversation control of third party device.All number assignment and conversation control are independently finished by IP phone terminal (6).The structure of whole communication network constitutes by the various types of communication terminal with based on the Internet of IPv6.The dual role that communication terminal of the present invention (6) is held concurrently the server and client side.
Communication terminal of the present invention (6) can generate one by user-defined loCal number according to user preferences, and this number can be the combination of character and numeral.Communication terminal of the present invention (6) can be set the incoming call restriction of number, can shield specific number or number segment.Communication terminal of the present invention (6) promptly can make a call, also can receipt of call.If communication terminal of the present invention (6) causes self IP address change because of certain reason, this terminal (6) can send to miscellaneous equipment or the terminal of once getting in touch with (6) with information such as new addresses automatically, removes some connection of non-artificial deletion.
The application of communication terminal of the present invention (6) has all surmounted traditional communicating by letter greatly with convenience.Except the most basic voice communication, all right additional video of communication terminal of the present invention (6), mail, the communication of types such as short message, fax, videoconference.Can also finish web page browsing, novel business such as ecommerce.For the calling transfer of traditional communication, caller identification etc. are let alone.The communication system that is made of communication terminal (6) is paid the usage charges of the Internet except needing the user, in communication without any expense.

Embodiment
Internal structure:
The most basic internal structure of communication terminal of the present invention (6) is seen Fig. 6, and it comprises control unit (9) and is attached thereto keyboard unit (10), network interface unit (11), memory cell (12), audio coding and decoding unit (13) and the display unit (14) that connects.Wherein audio coding is connected with loud speaker (17) with microphone (16) with D/A switch part (15) through mould/number with decoding unit.Control unit (9) is the control centre of terminal (6).Keyboard unit (10) is finished the processing to keyboard input information, and carries out data interaction with control unit (9).Network interface unit (11) then provides wired or wireless internet interface, and carries out data interaction with control unit (9).The main configuration information that stores in the memory cell (12), address list, contents such as link information, and carry out data interaction with control unit (9).Audio coding and decoding unit (13) are mainly finished the work of the Code And Decode of voice data, and with control unit (9) and mould/number, D/A switch part (15) is carried out data interaction.Mould/number, D/A switch part (15) is mainly finished the conversion work of simulated audio signal and digital audio and video signals, is responsible for gathering the signal of microphone (16), and outputs signal to loud speaker (17).Certainly terminal (6) can also add a lot of other functions, for example can add the coding and decoding video function, with as visual communication terminal.Each functional module can be also can integrating of disperseing physically, each functional module can be software also can be hardware.
Network configuration:
The communication system that is made of communication terminal of the present invention (6) is a kind of peer network architecture of complete P2P pattern.See Fig. 5.Because the facility on the address space that the IPv6 the Internet brings no longer needs NAT device on the network, all devices on the IPv6 the Internet can directly intercom mutually.Therefore, between the communication terminal (6) based on the IPv6 the Internet, and the communication system and the network that are constituted between communication terminal (6) and the miscellaneous equipment are more simple, only need IPv6 the Internet and communication terminal of the present invention (6) just much of that on the hardware.
Number generates:
At first communication terminal (6) need possess the number of one group of energy unique identification terminal (6) except IP address and MAC (Media Access Control) address itself.It is in order to carry out identity difference each other on the internet that terminal (6) adopts the purpose of this sets of numbers.This sets of numbers should be solidificated in terminal (6) inside, acp chip preferably, and the perhaps inside of core memory, and this sets of numbers can not be modified, but this sets of numbers after allowing to encrypt is in transmission over networks.For safety, encryption method and key all can be changed.
Communication terminal (6) needed the number of the similar telephone number within self-defined one group of certain-length scope before communication.This sets of numbers can be numeral, character, or their mixing, sets according to user preferences fully.Also can select to generate one group of random number by system.
Address list is set up:
New communication terminal (6) need be relative after having generated new digit, friend, and people's such as colleague number adds in the address list.Before this, can be by directly importing the other side's IP address and port numbers, perhaps alternate manner, mail for example obtains contact person's address list.Communication terminal (6) can find contact person's address list automatically from mail, and joins terminal inner.This address list in the mail is encrypted, and it is different from the address list of mail itself.Communication terminal (6) can be automatically and the contact of the terminal in the address list after obtaining address list, and whether effective with the IP address of determining these terminals, if the invalid address, communication terminal (6) can require the other side's communication terminal (6) carry out the address renewal by mail.New communication terminal (6) also can be the information updating of self in the other side's address list.Is Email more satisfactory as the initial contact passage between the communication terminal (6).Set up in case connect between the communication terminal (6), this connection just is not easy to lose, unless all chronic frustrations are acted on behalf of in the IP address of communicating pair and address, even run into this situation, communication terminal (6) still can be networked once more, and gets in touch with automatically by modes such as mails, sets up new connection.Communication terminal (6) also can carry out occasional call by direct input the other side's IP address and port numbers, still runs into situations such as address modification, and these interim connections also can be updated automatically, remove non-artificial the restriction.
Information-change:
In some cases, the IP address of communication terminal (6), MAC Address, information such as loCal number can change.If run into the change of these similar information, the information after communication terminal (6) can upgrade these automatically in time sends to other terminal and the equipment of once getting in touch with.Reliable with what guarantee to communicate to connect.These terminals of getting in touch with can be the equipment in the address list, also can be the equipment that once temporarily made a call in the non-address list, remove non-artificial the restriction.Because interim calling may be quite a few, especially professional various commercial department can make communication convenient more but store occasional call, but also consume bigger memory space in the communication terminal (6).
Data encryption:
Communication between the communication terminal (6) need be carried out data encryption.The best mode of data encryption is an asymmetric encryption techniques.Communication terminal (6) has PKI and private key.PKI is openly given other terminal, and private key is stored in this communication terminal (6) inside, and can not be arrived by external device access, can not be checked by this machine user simultaneously, only as the deciphering to external data.Because it is unidirectional having adopted asymmetric encryption techniques, encryption and decryption.Therefore data on the network can compare safety.If add regular update PKI and private key, the difficulty that data are cracked will be bigger.
The address list search:
Because the number in the address list comprises the independent assortment of character and numeral.In order to search the convenience of number, can handle the contact person who often uses with shortcut on the one hand, need to improve search efficiency on the one hand, part word during the user only need Enter Number, key character, phonetic or write a Chinese character in simplified form etc. just can navigate to this address list information rapidly.
Call flow:
Suppose that two communication terminals (6) have all had the address list that comprises the other side's information.The process of call is so so: at first, the calling subscriber need search for the other side's number (18), and caller has been imported after the several key characters or numeral in the number seldom, and calling number has just appeared on the screen.At this moment the calling subscriber begins to call out the called subscriber, and calling subscriber's communication terminal (6) finds the IP address and the port numbers of this called subscriber's correspondence, and information (19) such as PKI.Calling terminal (6) is with called subscriber's public key encryption data and send to terminal called (6), the called process (20) of calling that Here it is.Terminal called receives after the data of this calling that at first the private key with self carries out data decryption, and whether analyze the distant terminal identity true.If every data of the other side's terminal can both with the information correspondence in the address list, then can receipt of call, terminal called (6) ring, and display of calling number (21).Next be exactly called subscriber's extracts and both sides' communication process (22).A caller or a called side's user understands first on-hook (23) behind the end of conversation, produce an information after the on-hook, this information can be sent to the opposing party's terminal (6) by the terminal (6) of first on-hook, and the opposing party's terminal (6) is received this information and stopped communication process (24).
Roaming mechanism:
According to the IPv6 white paper, no matter be connected link-local or move to field network, always mobile node is by the local address addressing.The IP address that is to say mobile device can not change when changing to other access network yet.The realization of certain this mechanism be unable to do without the home agent equipment on the home link.This network plan provides convenience for the roaming of portable terminal (6), is particularly advantageous in the situation that a large amount of associated each other portable terminals (6) is roamed simultaneously.But in the present invention, also will consider some special circumstances, for example agent equipment lost efficacy, or the information such as IP address that cause of other reason situation about being modified, if run into these situations, terminal (6) can be automatically with oneself information after changing by network directly or indirectly notice and own other terminal (6) of getting in touch.When roaming, when especially carrying out the access network switching, for real time communication, IPv6 is difficult to provide and the GSM similar sub-district of mobile system seamless switching mechanism such as (Global System for Mobile communication).That is to say that in the real time communication process in order to guarantee communication quality, portable terminal (6) does not preferably carry out network and switches.For the present invention, the largest benefit that IPv6 brings is, portable terminal (6) can be in worldwide free-roaming, intercommunication mutually, and can be not out of touch.
Security mechanism:
For assault, the communication between the communication terminal (6) need be carried out data encryption to prevent stolen tin.Communication terminal (6) internal data and data and network are isolated as far as possible.Communication terminal (6) needs to adopt the mechanism of similar fire compartment wall to limit dangerous connection.
After each communication terminal (6) internal information is upgraded, communication terminal (6) can be automatically to inner information encryption and backup to storage card, in the equipment such as Email.
Communication terminal (6) is if stolen or lose, and communication terminal (6) can require machine primary input password to confirm when upgrading in the IP address, otherwise refusal work.So just greatly limited the situation that communication terminal (6) is illegally used.Lose (6) if the machine master finds terminal, and the machine master can on miscellaneous equipment or terminal (6), require other terminal (6) or the equipment termination in the address list and lose being connected of terminal (6) by the end message of backup.After treating that the user has new terminal (6), just can recover raw information, carry out the networking work of new terminal (6).
