Description
Technical field:
The present invention relates to the remote control technology of the networking telephone, proposed especially a kind of long-range implementation method that the phone of appointment is dialled.
Background technology:
Traditional dialing be with the keyboard of phone own as the direct control object, in the whole dialing procedure of phone, the operation of telephone state and behavior all is that the button by phone itself operates input.For the input operation of telephone number, the drawback of this input mode also is apparent.When the digital keys on using phone carries out the manual dial, after obtaining dialing numbers, to write down one by one first, again by manual key-press input number.In this whole process, artificial participation the transmission of telephone number, for some numbers that are of little use or the more number of figure place, the probability that man memory makes mistakes can be very high, and in order to improve the accuracy of transmitting number, need again to spend the more time to check numbers and repeatedly confirm.The time of these affirmations has been far longer than the time of dialing itself.Last in case mistake appears in dialing, just need again to dial again.Not only efficient is low for the mode of the manual dialing of this class, and error rate is high, and has consumed greatly people's time and efforts.
With respect to manual dial mode, another kind of dial mode is that telephone number is deposited in the phone in advance now, will search for first the location when dialing, and confirms afterwards dialing.This mode has had raising in the link of dialing, has guaranteed the quick and accuracy of dialing, but for the new digit that does not have in the phone, when using for the first time, or needs to use the mode that manually Enters Number.When phone is just brought into use, the typing number also will be spent a lot of times, and this improved procedure is in the problem that does not fundamentally still solve manual operation, more seriously, the number that causes preserving is lost in case phone breaks down, and so all records need again to re-enter.
So above these are dialed mode can not adapt to high efficiency, low-risk use and operational requirements.
Summary of the invention:
The objective of the invention is to dial in the mode in order to solve black phone that dialing is easily made mistakes, troublesome poeration, the not high drawback of efficient, thereby a kind of implementation method of remote dial of Internet phone has been proposed.
Generally, the implementation method of the remote dial of Internet phone of this innovation integrates SIP (TheSession Initiation Protocol session initiation protocol) phone and control end software exactly.By coming with control end software to the dialing of SIP phone, so that can add afterwards more control end to the control of SIP phone (following or title phone).We are defined as the implementation procedure of this technology " Dialer Mode " (dialing mode).
As mentioned above, realize the technique effect of this dialing mode that the present invention proposes, need to support sip server, remote computer (being control end) and the SIP phone of " Dialer Mode " at hardware device.Need to finish following four flow processs.Concrete technology contents is as follows:
Phone and control end are registered at sip server jointly: the user uses phone and control end, uses identical account at server registration both;
Phone is set up related from REFER (reference) message of sip server with control end by receiving: during REFER (reference) message that phone confirmation of receipt from the server of registering with this phone is registered, the facility information that all registered these phones of binding are arranged in the Contact header fields in the message, these equipment comprise control end equipment, like this so that phone can receive these REFER that binds the equipment of this phone (reference) message.On the other hand, after succeeding in registration, control end will send immediately a SIP OPTIONS (option) message request to the phone that bundlees, this phone will be re-registered, and from REFER (reference) message of server feedback, obtain the facility information tabulation of up-to-date this phone of binding, so that this phone receives its REFER message behind the address of that control end that obtains the request that sends.
Control end realizes that by sending REFER (reference) message the dialogue machine dialing controls: after phone and control end all succeed in registration, phone receives REFER (reference) message of sending from control end under idle condition, comprised the address of calling out in the Reference News, thereby replace the push-button dialing of phone own, it is pointed out that and do not have the feedback of calling this moment at control end;
Phone sends INVITE (invitation) message to the callee according to REFER (reference) message that receives by sip server: send a control signal directly to the phone place by control end, phone is received control signal, auto dialing after processing sends connection request to server;
After phone receives SIP REFER message and confirms, must return a 202Accepted message to the sender; To ignore it after unverified SIP REFER message of SIP phone acquisition, although the user can't see message, the SIP phone will be beamed back the response of refusal; After last that receives the callee set up conversational response, a notification message that comprises conversational response can send to control end.
Overall technique effect according to above scheme comprises:
1. phone and remote terminal connect, and the number of phone is the key-press input by phone not, but is automatically transferred to by phone after the control command by the receiving remote terminal.
2. the number dialed of phone is kept at long-range control end, and number sends on the phone with control information.
3. communication process carries out between phone and server all the time.
In addition, realization of the present invention basis is to rely on a long-range terminal session machine to operate control to finish.Long-range terminal specific implementation can be the platform computer, corresponding control software must be installed on the computer just can operate.
Certainly, in fact can be summarized as for dial mode: find the phone that to dial at control end, afterwards number is sent on the telephone set, dialled by phone.The afterwards connection of conversation is always carried out between telephone set and sip server.
On the other hand, using computer in this programme also is significant as the advantage of control end, and that embodies in the application with the Internet especially is more obvious.Its advantage has 2 points:
The first, be the Email by receiving in the source of the telephone number of routine office work, the information that also has the search and webpage data to obtain.For these digitized telephone numbers, as long as the number information on the direct screen printing directly sends to phone with it and just can breathe out, or they are stored in the phone directory of control end of software preserve, make things convenient for later searching and dialing.In this process, people do not need to participate in the transmittance process of number and go, and have so just greatly improved the accuracy of number call.Even a large amount of strangeness numbers is arranged, dialing these numbers also is easily, and people do not spend and are concerned about that the number oneself dial specifically which numeral is made of, and is that whose is set aside is just passable as long as know this number.
The second, as operand, the capacity of comparing phone itself on the quantity that telephone number is stored is many greatly with computer, and fail safe is also high.On the locating function of a large amount of telephone numbers, than directly on phone service speed faster, the accuracy of search is higher.

Embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, further set forth the present invention below in conjunction with concrete diagram and embodiment.
As shown in Figure 1, the present invention program can be summarised as simply according to diagram: the registration of phone and control end; Phone is set up related with control end; Control end sends number to phone; Phone obtains number and goes on foot to server dialing four.The specific implementation process is as follows:
(1) registration of phone and control end;
Owing to comprise the sip server of supporting Dialer Mode mode in the scheme, and this server support being the function that same user registers a plurality of equipment.Such as, can register simultaneously a SIP phone machine and any control end that other can be supported, to a user account number.
The detailed process of phone and control end registration is shown in 4:
The first step all behind the access network, sends registration request to sip server at phone and control end.
In this step, the registration process of phone and control end is similar.They pass through register interface separately, receive the required user name of registration, password, and the address of the server of registering.
Second step, phone and control end convert log-on message to respectively the form of sip message, and add therein Dialer Mode label, illustrate to open Dialer Mode function, then send registration request to server.
The 3rd step, the server process registration request.Server can be processed according to the user profile in the log-on message and user's device type, and for identical user profile and different device types, if opened Dialer Mode function in the application for registration, server can carry out association with them.
In the 4th step, phone and control end receive the result of registration, and the result is presented on the screen.If all succeed in registration, for phone, only show default user name, at control end, have the demonstration that is in state of a control.Arrive this, the registration process of phone and control end all finishes.
When the user uses SIP phone and control end (under dialing mode) like this, as long as use identical account after the server registration success, just can use both.Such as arrow note 1 and 2 among Fig. 2 (precedence is irrelevant).Wherein, control end is equipped with SIP phone control software, and control end, SIP phone and server are all supported Dialer Mode mode.
In addition, sip server can be a platform independent machine, also can be the network that a plurality of interconnected servers form.
(2) phone is set up related with control end;
For the sake of security, it is restricted that the SIP REFER message (sip message type) that the SIP phone is received comes initialization to call out.So the SIP phone will receive REFER message from agency and the registrar that phone has configured.So how find software control end or its IP address? we use a mechanism describing registration request in SIP RFC3261: the information that must list current all bindings in response message.That is to say, after sending the SIP registration message (the SIP phone every 120 seconds once), the equipment of all registered binding the machine is arranged in Contact header field (Contact header fields) in the affirmation message that obtains, comprise software control end equipment.The SIP phone can receive the SIPREFER message of all devices in the tabulation.SIP-URL (URL(uniform resource locator)) can be IP address or DNS domain name, both can.This tabulation is at any time what change, all will check once when registering at every turn.
Will move after general SIP phone starts, and software control end is moved with launch computer always.After SIP phone maximum has time-delay in 120 seconds, after again registering, could receive the message of software control end.
In order to solve this interval of 2 minutes, after succeeding in registration, software control end will send immediately a SIPOPTIONS (option) message request to the SIP phone, such as arrow note 3 among Fig. 2, with being re-registered, the SIP phone obtains up-to-date tabulation, such as arrow note 4 among Fig. 2, in order to obtain receiving behind the address of software control end the REFER request of software control end.
In order to identify and distinguish this specific SIP OPTIONS request, to add a privately owned X-header in the message.(summary) as follows:
x-ippbx-dm-supported
OPTIONS?SIP:IPAddress?SIP/2.0
Via:…
Contact:<SIP:user@test.com>；tag＝123456
To:<SIP:user@test.com>
From:<SIP:user@test.com>；....
X-IPPBXDialerModeCommand:regi?ster
This new x-header is called " X-IPPBXDialerModeCommand ", and value is " register ".This x-header has been arranged, received specific SIP OPTIONS message after, phone just needs immediately registration.
This OPTIONS message only just can be sent after software control end succeeds in registration.Moved a very long time when software control end, the SIP phone is registered after it, and this OPTIONS request just can not be sent out so, because just comprised up-to-date tabulation in the response message that obtains after the SIP phone succeeds in registration.The SIP phone will receive all SIP REFER message on configuration registry and the acting server.
Another one checks that the method for SIP REFER message is that SIP phone user increases netmask (NETMASK) when configuration DNS domain name or IP address.If what the sender address of SIP REFER was identical with the DNS domain name or the configuration of IP address scope is interior can be received.This inspection must be from sender of the message's address (the IP address that message sends), rather than obtains from message content.In the web configuration interface, can see this option.
If it is DHCP (DHCP) pattern that the user uses the main frame of software control end, when each the startup, all can obtain a new IP address.In this case, the user just can the configuration of IP address scope or is received REFER message with the DNS domain name so.
(3) control end sends number to phone;
After SIP phone and control end all succeed in registration, the SIP phone can receive SIP REFER (reference) message of sending from software control end under idle condition, such as arrow note 1 among Fig. 3, comprise the address of calling out in the SIP REFER message, so just can replace the push-button dialing of SIP phone own.Present stage, there is not the feedback of calling out in software control end.
All calling controls (beginning and terminated call) are all by finishing by sip message at sip server and equipment room.Certainly, an exception is wherein arranged: the SIP REFER message of software control end is directly to send to calling of SIP phone initialization.
(4) phone obtains number and dials to server;
The SIP phone will receive REFER message and send INVITE (invitation) message to the callee, shown in arrow note 2 among Fig. 3 by sip server.According to the description of RFC3515, REFER information increases a description makes the sender know the current state of calling.
The SIP phone is supported SIP, comes calling of initialization so we call out control by software control end with SIP.This is a SIP REFER method (with reference to RFC3515).Send a control signal directly to SIP phone place by control end, phone is received control signal, and auto dialing after processing sends connection request to sip server.
After the SIP phone receives SIP REFER message and confirms, must return a 202Accepted (acceptance) message to the sender.(with reference to the RFC35152.4 chapters and sections)
Generally after returning 202Accepted message, also can send a NOTIFY (notice) message, expression REFER has created an implicit description.All NOTIFY comprise the sip message that returns from the destination.
SIP REFER message comprises " Refer-To: ", the SIP-URL of called destination (Uniform Resource Identifier).Send INVITE after the SIP phone receives REFER message, will for this SIP-URL.
To ignore it after unverified SIP REFER message of SIP phone acquisition, although the user can't see message, the SIP phone will be beamed back the response of refusal.
The below is that the SIP phone responds the tabulation of " dialing control " under different conditions:
1. phone is idle, and microphone has not been plucked;
To dial and open loud speaker and send alarm call, until the user has plucked microphone.
2. phone is idle, and microphone has been plucked;
To dial and in microphone, play alarm call.
3. phone ring (Inbound Calls), and microphone has not been plucked
Ignore this dialing request and return " 486Busy Here " (current 486 is busy) message.Inbound Calls can not be cancelled.
4. phone is in talking state;
Phone is with current maintenance current talking and forward 2nd line (second speaking wire) to and dial.
5. phone is in the maintenance talking state;
Phone will dial at 2nd line (second speaking wire).
6. phone is in dialing and waits for on-state;
Carry out the dialing request at this line after current calling will be cancelled, and in loud speaker or microphone, play alarm call according to off hook state.
7. phone is in not-connected status (busy tone, generally connection);
Carry out the dialing request at this line after current calling will be cancelled, and in loud speaker or microphone, play alarm call according to off hook state.
8. the existing calling of phone is in hold mode, and another conversation is not-connected status (waiting pending, alarm);
Call request will be rejected and return " 486Busy Here " (current 486 is busy).The conversation that keeps can not be affected.
9. the existing calling of phone is in hold mode, and another conversation is not-connected status (busy tone does not generally connect);
Call request will be rejected and return " 486Busy Here " (current 486 is busy).The conversation that keeps can not be affected.
Phone have two conversations (in the conversation, maintenance, incoming call jingle bell ...);
Dialing is asked unsuccessfully.Current conversation is unaffected.Phone returns " 486Busy Here " (current 486 is busy) response.
After last that receives the callee set up conversational response, a NOTIFY that comprises conversational response can send to software control end.Whole process finishes.
In actual use, on control end, first operating software control end, and succeed in registration at server, make it to operate under the dialing mode.Equally, use identical number that phone is also succeeded in registration.
Then, we can directly select telephone number from webpage, then select specified option just can dial at once.In mail, also can make and use the same method to dial (referring to Fig. 5).Or enter the phone directory that software carries, select wherein number dial (referring to Fig. 6).
At last, waiting the other side to respond afterwards just can converse at phone.Whole process is quite simple, and the user need not remember any number.Compare traditional dialing procedure, dialing procedure of the present invention has been jumped out the pattern of push-button dialing, has realized the purpose that finding can be dialled, and ease for use is very strong, greatly shortens on the dialing time, and has avoided to greatest extent the mistake dialing.And rely on the powerful disposal ability of control end, be better than the direct control of dialogue machine at the store and management of telephone number.
Above demonstration and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
