Embodiment
The present invention is described in detail below by the drawings and specific embodiments.
In order to be implemented in a plurality of users of registration on the same SIP phone terminal, and the purpose that a plurality of users that registered can use this SIP phone terminal to converse, the present invention adopts the multi-process technology in the embedded system of SIP phone terminal, a master control process and a plurality of user agent's process just are set.Wherein user agent's process is carried out caller/called operation and registration/cancellation operation to each registered user, the collaborative work between the master control process control user agent process.In actual conditions, but the master control process all is to intercom mutually relatively independent software state machine with user agent's process.
In the present invention, each user agent's process is responsible for acting on behalf of corresponding user and is realized various operation and maintenance users' various states, and for example proxy user is registered to the SIP registrar server of network, and repeats to upgrade according to designated period.When the user operates that the SIP phone terminal makes a call or the SIP phone terminal receives when calling out, on behalf of corresponding user, each user agent's process generate request, send request, processing response according to user profile, and the message that receives carried out operations such as method parsing, header parsing, contents processing, application extension, generation response, and after the Signalling exchange success, call corresponding software and hardware resources and set up the bi-directional session passage.Therefore, each user agent's process can realize user agent (UA) function that defines in the Session Initiation Protocol.
Below with reference to Fig. 1 overall procedure of the present invention is described.As shown in Figure 1, at first in step 101, a master control process is set in the embedded system of SIP phone terminal.The embedded system here is the software and hardware system that adopted of SIP phone terminal just.
In step 102, when a user utilizes this SIP phone endpoint registration, master control process prompting user imports user profile, and after the user profile that receives this user input for this user distributes an independent user agent process, and distribution is corresponding to the system resource of this user agent's process.The user profile here comprises user ID at least, just user's E164 number or URL address.
In step 103, when a user operates the SIP phone terminal when making a call, the master control process is determined this user's user ID according to the calling user information in the call request, according to user ID scheduling corresponding to user agent's process of this user and to write down this telephone terminal be seizure condition, this user agent's process is carried out Signalling exchange then, to attempt to be established to called subscriber's conversation connection.
When the SIP phone terminal receives calling for a user, the master control process judges whether this telephone terminal is seizure condition, and when telephone terminal is not seizure condition, determine this user's user ID, corresponding to user agent's process of this user and to write down this telephone terminal be seizure condition, this user agent's process is carried out Signalling exchange and is set up session channel according to user ID scheduling.
Overall procedure of the present invention has been described above, and the registration process, SIP phone terminal that the user is described in conjunction with Fig. 2, Fig. 3 and Fig. 4 respectively again is as calling party's processing procedure and the SIP phone terminal processing procedure as the callee below.
In an embodiment of the present invention, have a display screen on the SIP phone terminal, a liquid crystal (LCD) display screen or the like for example, this display screen can show and user's registration and the relevant information of conversation.
Fig. 2 shows user's registration process.As shown in Figure 2, before user's registration, what at first show on the display screen is common user interface, comprises the button that increases the user on this common user interface.In step 201, the user has selected the increase user button, requires user of new registration on this SIP phone terminal.In step 202, show new user setup interface on the display screen then, require the user to import user profile and sip server information.The user profile here comprises user ID at least, just E164 number or URL address, and the user can be provided with these two simultaneously certainly.In addition, user profile can also comprise the characteristic the tinkle of bells that the user is provided with, with same SIP phone terminal on other users' of registering the tinkle of bells distinguish mutually.User profile can also comprise user cipher, go into to call out password and operation interface password or the like, wherein can user cipher be use the set password of this SIP phone terminal to the user, going into to call out password is the password that the requirement user imports when receiving calls, and the operation interface password is the password that the requirement user inputs when entering user interface under off-hook condition.Certainly can understand, these three passwords can be identical, also can be different.In order to prevent the user because carelessness is provided with wrong password, all passwords all need twice affirmation.
In addition, here also can be in the SIP phone terminal an integrated intelligent card read/write device, the user does not need interim input like this, but the smart card that will comprise user profile inserts the intelligent card read/write device of SIP phone terminal, and intelligent card read/write device extracts the user profile in the smart card and sends to the master control process then.
In step 203, after the user confirmed input, whether complete sum was legal for the master control process check user's of SIP phone terminal input information, if, execution in step 204, otherwise turn back to step 202, just reenter new user setup interface, this moment, the user can re-enter user profile.
In step 204, the master control process is that the user that increases newly is newly-built and distribute an independent user agent process, is the corresponding resource of this user agent's course allocation then, for example stores memory headroom of this user profile and state or the like.After this, master control process notifies user agent's process to bring into operation.
In step 205, user agent's process is acted on behalf of the SIP registrar server registration terminal of this user in network.
In step 206, the SIP registrar server in the network judges whether user's registration is successful, if, execution in step 207, otherwise execution in step 208 and subsequent step thereof.
In step 207, display screen shows the special interface under this user, and this user can call and carries out user's setting by special interface.Certainly, if in step 202, be provided with the operation interface password, user agent's process prompting user input operation interface password before the special interface of explicit user, and after user's input, judge whether the user imports correct.And only import under the correct situation the user, just show the special interface that this user is affiliated.
In step 208, user agent's process of SIP phone terminal is sent corresponding prompt information receiving after network beams back the message of the user's registration failure that comes to the user, for example shows the notice of registration failure on display screen to the user.
In step 209, user agent's process of SIP phone terminal judges whether the user abandons registration, if, execution in step 210, otherwise execution in step 211.Here judge that whether the user abandons registering for example is to judge whether the user has selected the discard button on the display screen.
In step 210, if the user does not abandon registration in the given time, user agent's process of SIP phone terminal judges further whether the user needs to re-enter information, and for example the user has selected the button of the information of re-entering.If, get back to step 202, just reenter new user setup interface, the user re-enters for example address of sip server then, and then execution in step 203 and subsequent step thereof.If the user does not select to re-enter, then same execution in step 211.
In step 211, the master control process is cancelled user agent's process of this user, and display screen enters public main interface then.
So far finished user's registration process, for each new user, the master control process is newly-built and distribute an independent user agent process for it, and distributes respective resources.The registered user is when nullifying, and the master control process is cancelled user agent's process of this user, and discharges respective resources.
Fig. 3 shows the processing procedure of SIP phone terminal as the calling party.In step 301, when user's off-hook, the master control process of SIP phone terminal is inputed user name and user cipher by display screen prompting user, judges in step 302 whether the user cipher of user's input is correct then.If, execution in step 303 and subsequent step thereof, otherwise turn back to step 301, require the user to re-enter user name and user cipher.
In step 303, it is seizure condition that the master control process is provided with current SIP phone terminal.
In step 304, the master control process is determined user ID, and dispatches user agent's process of this user's correspondence.Here determine that user ID is to determine by the calling address information in the INVITE request of analyzing calling subscriber's initiation.
In step 305, user agent's process is waited for subscriber dialing, enters call flows after subscriber dialing.The call flows here is identical with the call flows of existing SIP phone terminal, repeats no more here.
The situation of SIP phone terminal as the calling party has been described above, if the SIP phone terminal as the callee, its handling process is as shown in Figure 4.
At first in step 401, the master control process of SIP phone terminal detected call out enter after, check the seizure condition of telephone terminal.
If the front has illustrated when the SIP phone terminal makes a call as the calling party, for example the user A that registers on this SIP phone terminal makes a call as caller, it is seizure condition that the master control process can write down this terminal, this moment, it was seizure condition that the SIP phone terminal can detect telephone terminal when another user B that another user C registers on the SIP phone terminal that user A is conversing by another SIP phone terminal call.In addition, if user A converses as called this SIP phone terminal of using, it is seizure condition that the master control process also can write down this terminal, equally, when another user B that another user C registers on the SIP phone terminal that user A is conversing by another SIP phone terminal call, it is seizure condition that the SIP phone terminal also can detect telephone terminal.Corresponding, no matter be as caller or called, after the user finished conversation, the master control process can terminal be set to idle condition.
In step 402, the master control process judges according to testing result whether telephone terminal is occupied.If do not have occupied, execution in step 403 and subsequent step thereof, otherwise execution in step 406 and subsequent step thereof.
In step 403, the master control process is determined called identification according to the called address information in the INVITE request that receives, and telephone terminal is set to seizure condition, calls then corresponding to this called user agent's process.
In step 404, the characteristic the tinkle of bells ring that user agent's process is provided with this user, and on display screen display of calling information and called party information, wait for that the called subscriber answers.
In step 405, when called subscriber's off-hook is replied, user agent's process is carried out Signalling exchange and is set up and calling subscriber's session channel.After this, when called subscriber's on-hook end conversation, the master control process can be set to idle condition by telephone terminal.
In step 406, if it is just occupied that the master control process is judged telephone terminal, for example user A converses, and master control process so has a new calling for user B to enter to user A prompting, shows on terminal display screen that then corresponding operation interface is for user A selection.In the present embodiment, user A can have three kinds of selections: refusal is newly called out, is kept current talking and finishes current talking.
In step 407, the master control process is judged the content that user A selects after user A has carried out selecting, call out execution in step 408 if refusal is new; If the maintenance current talking, execution in step 409 and subsequent step thereof; If the end current talking, execution in step 412 and subsequent step thereof.
In step 408, if user A selects the new calling of refusal, user agent's process of master control process scheduling user B, this user agent's process sends the busy response message of the called SIP phone terminal of sign to the calling subscriber.User A continues conversation in this process, and sip terminal is set to idle condition behind end of conversation.
In step 409, if user A select to keep current talking, user agent's process of master control process scheduling user B, this user agent's process be to user B ring, and on display screen display of calling information and called party information, wait for that user B replys.In step 410, user B inputs into the calling password and receives calls, and the operation interface of display screen explicit user B behind the password of input operation interface, and user B off-hook is replied then, and user agent's process of user B is set up session channel.In step 411, user B finishes to remove the session channel of setting up for the conversation of user B after the conversation, and user agent's process of dispatched users A is continued the conversation processing of user A by user agent's process of user A then.
In step 412, if the active user selects to finish current talking, user agent's process of master control process scheduling user B, user agent's process of user B be to user B ring, and on display screen display of calling information and called party information, wait for that user B replys.In step 413, user B inputs into the calling password and receives calls, and the operation interface of display screen explicit user B behind the password of input operation interface, and user B off-hook is replied then, and user agent's process of user B is set up session channel.In step 414, after stopping to converse, removes user B session channel, and sip terminal is set to idle condition.
Like this, the present invention provides flexible processing mode for the user in the SIP phone terminal when called, has solved a plurality of users register the different user conversation that causes easily on same SIP phone terminal coordination problem.
Certainly, the user B here also can be user A oneself, that is to say, when user A is conversing, might another user C also wish the conversation with user A, and this is that user A can find that one new is gone into to call out, and this go into to call out called be oneself.Similar to the above embodiments, user A can have three kinds of selections equally, and only master control process can not dispatched new user agent's process, but continues to carry out new processing by original user agent's process.
In addition, for easy flow process, can in step 406, not provide selection to user A yet, but be under the seizure condition in the SIP phone terminal, direct user agent's process by this user B of master control process scheduling, user agent's process of user B sends the busy response message of the called SIP phone terminal of sign to the calling subscriber, for example is " 486 response ".
Mention in front and can comprise an operation interface password in the user profile, the purpose that this operation interface password is set is misoperation or the free call on sb. else's expense through illegal means that prevents between the user, and for example user A uses the identity of user B to operate or communicate by letter.Under the situation that is provided with the operation interface password, the SIP phone terminal is when static wait state, and what display screen showed is for the shared public main interface of all users.When the user by off-hook operation, and when directly operating by terminal keyboard, the master control process only allows this user at public main interface operation, operation promptly belongs to public main interface for example " to add new user ".No matter the user is as caller or called, when user's off-hook, the prompting interface of display reminding user input immediately or selection user name and input operation interface password on the display screen, whether the checking of master control process then user input is correct, import explicit user operation interface under the correct situation the user, at this moment the user just can carry out number dialing telephone call or carry out operations such as user property is provided with.After user's on-hook or finishing setting operation, the display interface on the display screen turns back to public main interface immediately, after this if this user's off-hook need be inputed user name and operation interface password once more.
Therefore be appreciated that the above only is preferred embodiment of the present invention, or not within the spirit and principles in the present invention not all in order to restriction the present invention, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
