Background technology
Along with popularizing of communication equipments such as phone and mobile phone, serious day by day for reaching the malicious call problem that various purposes occur.Be regardless of the malicious call incoming call of the moment and occasion, seriously affect people's operate as normal and life; If pull out telephone wire or shutdown, might miss useful incoming call again.
Traditional PSTN (Public Switched Telephone Network, public switch telephone network) with soft switch (Softswitch) is NGN (the Next Generation Network of representative, next generation network) in, all provides the business that stops malicious call.The user terminal application should business after, need artificial input to allow to call out the calling number list of this user terminal or number segment (below be referred to as allow the call number storehouse) and storage, this permission call number storehouse can be kept on the user terminal, also can be kept in Server (server) equipment or independent database of this user terminal of management.Whether, as determine this calling number be the number that allow in call number storehouse, be the call setup that then allows this user terminal if when other-end this user terminal being called out, managing the number that the Server equipment of this user terminal can the inquiring calling user; Otherwise do not allow call setup to this user terminal.
Provide the equipment that stops call business to be generally management called subscriber's Server equipment.As the various calling Server of Softswitch, the VOIP net in PBX (Private Branch eXchange, telephone exchange), the NGN net of PSTN net etc.
In the prior art one provide stop call business the networking schematic diagram as shown in Figure 2, wherein, realize stoping the business of malicious call by Softswitch.In this networking, if the analog telephone A (user terminal) by the voice gateways access network stops the malicious call business to the Softswitch application, the user can report Softswitch to the telephone number that will allow to call out this analog telephone A, and the telephone number that will be allowed to call out this analog telephone A by Softswitch is stored in the permission call number database.If the mobile phone B of PSTN net will be dialed the telephone number of this analog telephone A, Softswitch can call out the telephone number of this analog telephone A according to the permission that allows to preserve in the call number database, and the number that comes electric hand B machine is verified.When checking is passed through, allow call establishment between mobile phone B and the analog telephone A.
Along with voice technology especially VOIP (Voice Over IP, voice call based on Internet Protocol) appearance of the development of technology and intelligent terminal, business more and more shifts to terminal, and the prevention malicious call business that belongs to the Server end is originally also shifting on intelligent terminals such as voice gateways and IP Phone, Soft Phone.At present, some voice gateways and terminal can provide simple anti-malicious call business, and it is to adopt the calling number verification mode to realize equally.
A flow process of the method for prevention malicious call may further comprise the steps as shown in Figure 2 in the prior art:
Step s201, user terminal are enabled and are stoped the malicious call business.
Calling number that step s202, user terminal interpolation permission are called out or number segment (as the number of some numeral beginning) are in permission call number storehouse; Adding method is included on the user terminal by the button input, perhaps directly setting such as (as the Softswitch in the PBX in the PSTN network, the NGN network) on equipment.
Step s203, when receiving the message related to calls to user terminal number, judge whether this user terminal has enabled prevention malicious call business, is then to continue, otherwise carry out step s209.
Step s204, judge whether there is calling number in the message related to calls, do not exist and then carry out step s205, exist and then carry out step s206.
Step s205, obtain the calling number of calling party input, continue step s206.
Step s206, in allowing the call number storehouse this calling number of inquiry.
Step s207, judging whether to inquire the calling number of coupling in the call number storehouse, is to illustrate that then calling number is the item that allows in the call number database, carries out step s209; Otherwise carry out step s208.
Step s208, finish the calling to the number of user terminal, stop to call out and proceed, flow process finishes.
Step s209, be established to the calling of the number of user terminal, flow process finishes.
Problems of the prior art are: in order to allow the calling that allows normally dial into simultaneously the malicious call prevention is lived, need the frequent renewal of user to allow the call number storehouse, along with the user uses being on the increase of number, very loaded down with trivial details and inconvenient to the renewal that allows the call number storehouse.Allow user A to call out oneself such as user B, and A mobile phone, office's base commonly used have been added permission call number storehouse; But A just can not be successful when using other phone (as household fixed telephone, public telephone) to call out B, allows in the number storehouse of calling unless these numbers are also joined B.In addition, some IP Phone or SoftPhone do not carry calling number or can arbitrarily fill in calling number by the user when making a call now, make above-mentioned method of calling out prevention according to calling number checking result become inaccurate.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The invention provides a kind of call-establishing method, as shown in Figure 3, comprising:
Step s301, when receiving the calling party, obtain the calling authority sign indicating number that the calling party sends about this call request to the call request of called number.
Step s302, when the calling authority sign indicating number that obtains with in advance for the calling authority sign indicating number coupling of the setting of this called number the time, be established to the calling of this called number.
In the said method provided by the invention, the user need be provided with one and call out the authority sign indicating number enabling when stoping malicious call professional.The set-up mode of calling out the authority sign indicating number can pass through the key mode realization of user terminal (as analog telephone, mobile phone, IP phone etc.), also can realize by the mode of direct configuration call authority sign indicating number on the network equipment of managing user terminal.Wherein, adopt the mode that directly disposes can be all user terminals of certain number segment or should business at a plurality of user terminal batch settings of jack per line section.After other calling partys when user's number is called out, the Subscriber Number place network equipment is verified the calling that the calling party initiates according to the calling authority sign indicating number that the user is provided with.Below to the calling authority sign indicating number setting that relates in the above-mentioned flow process of the present invention, call out the transmission of authority sign indicating number, call out authority code authentication flow process and be described respectively.
On the set-up mode of calling authority sign indicating number, can adopt the user directly the mode of calling out the authority sign indicating number or directly disposing and cancelling calling authority sign indicating number on the network equipment of managing user terminal to be set by the key mode of user terminal.
Concrete, with the key mode by user terminal calling authority sign indicating number being set is example, as shown in Figure 4, may further comprise the steps:
The network equipment of step s401, managing user terminal receives service code and the calling authority sign indicating number of user by the user terminal input.
Concrete, the user can be by user terminal incoming traffic sign indicating number and the calling authority sign indicating number that need be provided with.For example, * 589* represents to enable the service code that stops the malicious call business, 9876 to be provided with for the user calling authority sign indicating number the time, the user can import * 589*9876# by user terminal, wherein, # is an end mark.Digital set-up mode for calling out the authority sign indicating number can be provided with according to the custom or the hobby of individual subscriber.For example use Any Digit, user's birthday, the telephone key-press of initial letter of one's surname in Pinyin correspondence etc.Telephone key-press with the initial letter of one's surname in Pinyin correspondence is an example, in the existing telephone plant, numeral on the telephone keypad 2 corresponding with letter " ABC ", numeral 3 corresponding with letter " DEF " ..., numeral 9 corresponding letters " WXYZ ".With user name is that " Zhang Xiaoming " is example, and then initial letter of one's surname in Pinyin is " ZXM ", and the numeral on the corresponding telephone keypad be " 996 ", then the user calling authority sign indicating number can be set is 996.
The network equipment of step s402, managing user terminal judges whether service code is effective, is then to proceed step s403, otherwise carries out step s405.
The network equipment of step s403, managing user terminal judges whether calling authority sign indicating number is effective, is then to proceed step s404, otherwise carries out step s405.
Step s404, broadcast are provided with successfully prompt tone, and the calling authority sign indicating number of recording user setting, and flow process finishes.
Step s405, broadcast are provided with the failure prompt tone, and flow process finishes.
After the user is provided with and calls out the success of authority sign indicating number, need to call out authority sign indicating number notice (as by modes such as phone, telecommunications, mail, faxes) to other users who allows the user terminal of its use of incoming call, inform that need import this when it dials this user terminal later calls out the authority sign indicating number.For the calling authority sign indicating number that the modes such as telephone key-press with birthday of user, initial letter of one's surname in Pinyin correspondence are provided with, the user can notify other users with the rule that is provided with, and is convenient to other users and remembers.
By above-mentioned flow process, realized calling out the setting of authority sign indicating number by the key mode of user terminal.For same user terminal, a plurality of calling authority sign indicating numbers can be set, and the different calling subscribers that different calling authority sign indicating numbers is distributed to are used, the purposes of different calling authority sign indicating numbers is identical, does not have essential distinction.Based on similar methods, can realize calling out the cancellation of authority sign indicating number equally.When for example passing through the key mode of user terminal, the user can be by user terminal incoming traffic sign indicating number and the calling authority sign indicating number that need be provided with.For example, * 599* represents to cancel the service code that stops the malicious call business, 9876 be provided with for the user calling authority sign indicating number the time, the user can import * 599*9876# by user terminal, wherein, # is an end mark.When the network equipment of managing user terminal passed through user's calling authority sign indicating number checking, this of cancellation user terminal called out authority sign indicating number.
For the mode that directly the authority sign indicating number is called out in configuration and cancellation on the network equipment of managing user terminal, only need the corresponding setting interface to be provided on the network equipment and function is set to get final product, user with administration authority can directly land the network equipment, carries out the setting and the cancellation of the calling authority sign indicating number of related user terminal.Be not described in detail at this for this mode.
As the calling party, can take following dual mode incoming call authority sign indicating number when called number is called out: (1) is directly continuous incoming call authority sign indicating number when the input called number; (2) voice suggestion of wait incoming call authority sign indicating number behind the input called number is according to the voice suggestion incoming call authority sign indicating number that receives.Below respectively both of these case and corresponding calling authority sign indicating number transmission means are introduced.
For the calling party, under the direct input mode of support call authority sign indicating number, need be to the calling subscriber by FXS (Foreign Exchange Station, FXS) Kou phone, PRI (Primary RateInterface, basic rate interface), R2, FXO (Foreign Exchange Office, FXO), E﹠amp; The number series of inputs such as PSTN (Public Switch Telephone Network, the public switched telephone network) phone that M connects, mobile phone is distinguished, and which number of distinguishing in the number series is that called number, which number are to call out the authority sign indicating number.For example at continuous input called number with when calling out the authority sign indicating number, can adopt two to separate called number and call out the authority sign indicating number for # number, then two be called number before # number, the back is calling authority sign indicating number.
After receiving the called number of the continuous input of calling subscriber and calling out the authority sign indicating number, the caller gateway can adopt dual mode will call out the authority sign indicating number and send to the callee, comprise calling authority sign indicating number added in the message related to calls to the callee sending, or send to the callee by being with outer transmission mode will call out the authority sign indicating number.
Below at first be introduced adding calling authority sign indicating number to send to the callee in the message related to calls mode.Concrete, when message related to calls be INVITE based on Session Initiation Protocol, the calling authority can be piled up and put in the privately owned header field Auth-Code of INVITE.When message related to calls is SETUP message based on agreement H.323, can piles up and put in the privately owned field of SETUP message calling out authority.
Pile up will call out authority that to put in the privately owned header field Auth-Code of INVITE be example, Auth-Code header field form is as " Auth-Code: character string ", wherein use syntactic representation to be based on ABNF (AugmentedBackus Naur Form, enhancement mode Backus normal form (BNF)) coding:
Auth-Code＝″Auth-Code″HCOLON?authcode-value
authcode-value＝string
The example of an INVITE that has increased the Auth-Code header field is as follows:
INVITE?sip:520@192.168.0.30:5060SIP/2.0
Via：SIP/2.0/UDP?192.168.0.80:5060；branch＝z9hG4bK1eab666be5a

Auth-Code:cbb9493f5f89d177d5fb66c6db08fdb5//calling authority sign indicating number obtains through cryptographic algorithm such as MD5 (Message-Digest Algorithm 5, md5-challenge) algorithm computation
……
This example implementation will call out the privately owned header field Auth-Code of authority sign indicating number by INVITE and send to the callee.For the example of the SETUP message of agreement H.323, similar to the execution mode of above-mentioned example, be not repeated in this description at this.
Mode for calling party's incoming call authority sign indicating number under the voice suggestion mode, the caller voice gateways only need the outer transmission mode of tenaculum to get final product, adopt the outer transmission mode of band to transmit and call out the authority sign indicating number, as the modes such as RTP (Real-time Transport Protocol, RTP) packet that adopt agreement RFC2833 regulation will be called out the authority sign indicating number and will be delivered to the callee.
Similar to the calling party, during calling, same support voice prompting mode of callee and the direct input mode of calling authority sign indicating number.Under direct input mode: at first detect whether carried calling authority sign indicating number (promptly resolving the privately owned Auth-Code header field in the INVITE of SIP or the privately owned field of SETUP message H.323) in the message that the calling party sends, if carried calling authority sign indicating number, then verified; If no, then enter voice suggestion input flow process.If not support call of callee authority sign indicating number business then can not be resolved the Auth-Code header field of INVITE or the privately owned field of SETUP message, directly skip, normally do not carry out so do not influence calling.
When callee's support call authority sign indicating number was professional, the flow process of callee's call-establishing method comprised as shown in Figure 5 among the present invention:
Step s501, receive call request to called number.
Step s502, judge whether this called number is provided with and call out the authority sign indicating number, be then to carry out step s503, otherwise carry out step s510.
Step s503, judge whether carried calling authority sign indicating number in this call request, be then to carry out step s507, otherwise carry out step s504.
Concrete, when message related to calls be INVITE based on Session Initiation Protocol, can check whether carried privately owned header field Auth-Code in the INVITE, then from privately owned header field Auth-Code, obtain calling authority sign indicating number if carry.When message related to calls is SETUP message based on agreement H.323, can check in the privately owned field of SETUP message whether carried calling authority sign indicating number, call out the authority sign indicating number if carry then from the privately owned field of SETUP message, to obtain.If do not carry in the call request and call out the authority sign indicating number, then can adopt voice prompting mode.
Step s504, voice suggestion incoming call authority sign indicating number.
The concrete mode of this prompting can include but not limited to following several:
Mode (one): do not point out in voice suggestion and call out the authority sign indicating number, for example voice suggestion is: " ask incoming call authority sign indicating number, press * bond bundle ".By this mode, have only other users that understand calling authority sign indicating number fully to call out to the user.
Mode (two): the authority sign indicating number is called out in prompting in voice suggestion, for example voice suggestion is: " asking incoming call authority sign indicating number; call out the birthday that the authority sign indicating number is the user that you called out " or " asking incoming call authority sign indicating number; call out the telephone key-press that the authority sign indicating number is the user's that you called out an initial letter of one's surname in Pinyin correspondence ", by this mode, can be so that the memory that other users of calling party call out the authority sign indicating number.And for other users that do not know suggestion content such as illegal caller, can't call out the user.
Mode (three): directly clearly call out the authority sign indicating number in voice suggestion, for example voice suggestion is: " ask incoming call authority sign indicating number, calling out the authority sign indicating number is 996 ".By this mode, can shield the calling of the user being carried out by software or computer because under the mode of unartificial calling, though in voice suggestion clear and definite calling authority sign indicating number, also can't correctly import.
Step s505, receipt of call authority sign indicating number by turn.
Concrete, the calling party is after receiving voice suggestion, and incoming call authority sign indicating number also sends by turn.
Whether step s506, judgement are called out the authority sign indicating number and are finished receiving, and are then to carry out step s507, otherwise return step s505.
Concrete, can judge that whether call out the authority sign indicating number finishes receiving, and for example when the content of judging calling party's input is " * ", judges from the calling party and finishes the reception of calling out the authority sign indicating number according to the content of calling party's input.
Step s507, verify calling out the authority sign indicating number.
Concrete, this method that calling authority sign indicating number is verified is specially: relatively whether more identical with the calling authority sign indicating number of setting for this called number in advance from calling party's calling authority sign indicating number, and then can think when identical by authentication, otherwise think not by authenticating.
Step s508, judge that this calling authority sign indicating number whether by checking, is then to carry out step s510, otherwise carries out step s509.
To the calling authority of this called number, flow process does not finish for step s509, prompting.Certainly can also require calling party's incoming call authority sign indicating number once more, when the calling authority sign indicating number of calling party's continuous several times input error, end and being connected of calling party.
Step s510, normal call are handled, and are established to the calling of called number, and flow process finishes.
The said method that the application of the invention provides, the mode that adopts the calling authority sign indicating number to called number to authenticate realizes the prevention to malicious call.Compare by the mode that calling number is verified with existing, do not need frequent renewal to allow the call number storehouse, do not need database storage to allow call number.On the network equipments such as voice gateways, intelligent terminal, just can realize powerful prevention malicious call function at an easy rate.Which calling number validated user for having obtained to call out the authority sign indicating number uses all can normally call out called number.And, revise calling number in any case for the user who does not call out the authority sign indicating number, and have only and do not call out the authority sign indicating number, all can't call out called number.
The present invention also provides a kind of network equipment, as shown in Figure 6, comprising:
