Description

Equipment, the method and system of registering/canceling, the service of control interruption-free
Technical field
The present invention relates to interruption-free service method and system, the system that relates in particular to registering/canceling interruption-free service method, control interruption-free service method and realize the interruption-free service.
Background technology
The interruption-free service (Don ' t Disturb Service) be a kind of telecommunication service commonly used, definition to this business in China's GB is: the interruption-free service is " Temporary Refusal of Call service ", can use this service under the situation that the user did not wish to have calling to disturb in a period of time.After this service of user applies, all callings will be answered by telephone office in generation, but user's exhalation is unrestricted.
Consult the total technical specification book of National Standard Ministry of Posts and Telecommunications telephony switching gear (appendix) ", stipulate that wherein the register method of interruption-free service is " an off-hook; Listen dialing tone; Press *56#; Response; On-hook ".Register successfully back " no longer need any operation, can make this phone exempt to be disturbed ".In addition, when the user wishes the override of do-not-disturb service, can pass through " off-hook; Listen dialing tone; #56#; Response; On-hook " and realize.
International and regional at other, the occupation mode of interruption-free service and the definition of China's GB are similar, and difference is mainly reflected in three aspects:
A) service feature sign indicating number difference (China GB regulation be " 56 ");
Can set the time that the interruption-free service is initial and/or cease to have effect when b) registering;
C) when the interruption-free service has been enabled, passing through special dial tone or verbal announcement under the situation of outgoing call with the special circumstances on the call user's attention line.
Especially, the interruption-free service also derives another kind of professional " password breakthrough interruption-free ", is also referred to as " super interruption-free " sometimes.The user is in registration " password breakthrough interruption-free " service, be provided with after the password simultaneously, if there is calling subscriber (other user) to call out this user, then network will point out the calling subscriber to input password, if the calling subscriber inputs correct password, then incoming call calling this time just can break through user's interruption-free setting and complete connection; Otherwise user's interruption-free is provided with and will the incoming call calling be come into force, and promptly refuses this incoming call calling.
At present, continuous maturation along with group technology, develop based on Circuit-switched conventional telecommunication network towards broadband telecommunication net based on packet switching, using SIP (SIP) then is one of current technology trends as the call control signalling of grouping telecommunications core network, for example ITU-T (International Telecommunication Association's TC Telecommunication Committee) and ETSI (ETSI) are to the formulation of NGN (Next Genteration Network, next generation network) standard.In this new analysis communication network, new block terminal-sip terminal will progressively replace traditional terminal phone.
Interruption-free also still needs to provide to the sip terminal user though applied environment has taken place to change as a service of popularizing in the conventional telecommunications net, and the interruption-free service that therefore provides to sip terminal in the grouping telecommunications network also will inevitably change:
A) at first, in the grouping telecommunications network, the supplementary service (interruption-free service) that block terminal (sip terminal) uses does not have " service feature sign indicating number " such notion, for example for sip terminal, professional registration and cancel the header field parameter that all will depend in the sip message, and the user can carry out professional registration and cancel, and no longer be by dialling the mode of " service feature sign indicating number " by the menu operation at sip terminal interface.Thus, the selection mode of simple menu has been simplified user's operation greatly, does not need the user to remember " service feature sign indicating number ", thereby has promoted the user to use professional frequency.
But, at present in sip message, also do not define which header field parameter and carry the operation information that the registration of interruption-free service is cancelled, therefore in the grouping telecommunications network, to when providing the interruption-free service, sip terminal must in sip message, define the header field parameter of carrying the interruption-free service related information.
Certainly, sip terminal inserts the packet interface of grouping telecommunications network, except supporting SIP, also can support http protocol simultaneously.Sip terminal also can be realized the registration of interruption-free service is cancelled by " WEB is self-service " based on HTTP.
B) secondly, in the conventional telecommunications net, the purpose of interruption-free service is that the user wishes " not wishing to have calling to disturb " in a period of time, but be well known that, Session Initiation Protocol is an agreement towards multimedia application, sip terminal is except can receiving incoming call calling (SIP INVITE), can also receive instant message (Instant Messaging), and multiple sip message such as subscription, as SIP MESSAGE instant message, the SIP INFO, SIP SUBSCRIBE message, the SIP NOTIFY, SIP REFER message, SIP PUBLISH etc.
These sip messages bring the interference bigger than incoming call calling may for the sip terminal user, bring countless " rubbish " instant message (resembling present refuse messages, SPAM) might for the sip terminal user as the SIPMESSAGE instant message; SIP REFER Reference News can make the sip terminal that receives SIPREFER message initiate sip message specified in this message in specified destination in this message of trend for another example, may bring very big harm to the sip terminal user.
In addition, in present grouping telecommunications network, sip terminal is to realize registration to the service of the interruption-free in the conventional telecommunications net by http protocol, register successfully after, the sip terminal user will not be subjected to the interference of incoming call calling.
Therefore, aforesaid prior art has following shortcoming:
First: because not all sip terminal all can support http protocol, then for not supporting the sip terminal of http protocol, because Session Initiation Protocol is not supported to the carrying of the operation information of the registration of interruption-free service, so can't use the interruption-free service.
Second: prior art is only supported the interruption-free service (only at incoming call) in the conventional telecommunications net, and SIP is the agreement towards multimedia application, if sip terminal is not supported to the interruption-free service of SIP MESSAGE message, SIP INFO, SIP SUBSCRIBE message, SIP NOTIFY, SIP REFER message, SIP PUBLISH etc. the user to be subjected to than the bigger interference of incoming call calling (SIPINVITE message).Do not support simultaneously to be the interruption-free service of present condition (for example busy) based on user's difference yet.
So, in the SIP supplementary service, be necessary to enlarge the extension of interruption-free service definition, the interruption-free service of a kind of " wouldn't accept the sip message service " promptly is provided, mainly be when the user does not wish to have sip message to disturb in a period of time, can use this interruption-free service; Simultaneously, when the sip terminal user uses the interruption-free service, can create interruption-free filtering rule to various SIP message; Similarly, " the password breakthrough interruption-free " business of deriving can be arranged also, the calling subscriber who promptly sends sip message has only under the situation of using correct password, just can break through the interruption-free service that the called subscriber is provided with; In addition, this interruption-free service should be applicable to all sip terminals.

Embodiment
The invention provides a kind of the grouping telecommunications network in the sip terminal user use interruption-free service method and system, wherein, the user registers the interruption-free service on sip terminal, establishment is based on the interruption-free filtering rule of sip message content and/or time and/or user's presentation information (presence information), and carry and pass to the network equipment, thereby realize the interruption-free service by the carrying of Session Initiation Protocol or http protocol.
Wherein, user's presentation information is the one group of attribute that characterizes current ability that communicates of user and wish, as User Status, user contact address etc.Because in the conventional telecommunication network, User Status (user terminal state) can only show as free time, SOT state of termination such as busy, and it uses application scenarios of interruption-free service to imply User Status to be " free time ", and can not distinguish user's the present condition that is this moment.But by the user's presentation information among the present invention, at SIP is in the grouping telecommunications network of core net call control signalling, even under user terminal is in idle condition, the user also can issue the different present conditions that is by sip message, such as " in session ", " driving " etc., thereby the application scenarios of the interruption-free in the grouping telecommunications network of the present invention service can be by presentation information, and distinguishes user's the present condition that is.
It should be noted that the interruption-free service in the grouping telecommunications network provided by the invention, be meant the SIP supplementary service of " user does not wish that in a certain period sip message disturbs under certain presentation information ".
Fig. 1 has shown the structure chart according to interruption-free service system 1 of the present invention.
As shown in Figure 1, the interruption-free service system 1 in the grouping telecommunications network comprises a plurality of sip terminals 2 (sip terminal A, sip terminal B etc.) and interruption-free service control appliance 3.
Wherein, serve control appliance 3 as the interruption-free of logical ne and provide the host execution environment, thereby provide the interruption-free service to sip terminal for interruption-free service logic controlled function.
Sip terminal 2 is connected with interruption-free service control appliance 3 by Session Initiation Protocol or http protocol, it should be noted that, this sip terminal 2 can directly or indirectly link to each other with interruption-free service control appliance 3, for example by other network element transfer, in the present invention, will be that example describes with the situation that directly links to each other.
And as physical entity, this interruption-free service control appliance 3 can for application server (ApplicationServer), inserted sheet, also can be first-class in soft switch.
To the 3 registration interruption-free services of interruption-free service control appliance, and interruption-free service control appliance 3 provides the interruption-free service to this sip terminal 2, can realize interruption-free method of servicing of the present invention by sip terminal 2.
Operation information is registered, cancelled to＜Session Initiation Protocol carrying interruption-free 〉
Before the interruption-free service that explanation realizes according to interruption-free service system 1 of the present invention, will at first the method by Session Initiation Protocol carrying interruption-free log-on operation information be described.
By the shortcoming of aforesaid prior art as can be known, provide the key of interruption-free service to be to sip terminal, sip terminal 2 must be by Session Initiation Protocol or http protocol interface to interruption-free service control appliance 3 carry out interruption-free registration, cancel operation, carrying is transmitted registration, is cancelled the relevant information of operation in this agreement.
Thus, the present invention is according to already provided SUBSCRIBE subscribing mechanism in the Session Initiation Protocol, sends SUBSCRIBE message to interruption-free service control appliance 3 registration interruption-frees by sip terminal 2.For realizing this function, the present invention has newly expanded " interruption-free " subscribe request in Session Initiation Protocol, is dnd with " interruption-free " incident package definition of correspondence, and transmits by the Event header field.Wherein need to define a series of parameter as follows for this dnd incident bag:
request：normal/override(override_pin)
msg：all/invite/message/subscribe/refer/info/notify/publish
start_time：now/delay(SIP-date|delta-seconds)
presence-status：token/all
available-inform：true/false
Wherein, the type of request parametric representation current " interruption-free " subscribe request.The common request registration interruption-free service of " normal " expression in the parameter value; " override " expression request password is broken through interruption-free, when using the request password to break through the interruption-free service, can also be provided with simultaneously and break through cryptographic parameter override_pin, this breakthrough password also can just be preset in the network before initiating the service operations of registration interruption-free by the user certainly.
Msg parametric representation current " interruption-free " subscribe request at which sip message comes into force." all " expressions come into force to all sip messages in the parameter value, (incoming call calling) comes into force to the SIP INVITE in " invite " expression, " message " expression comes into force to SIP MESSAGE message, " subscribe " expression comes into force to SIP SUBSCRIBE message, " refer " expression comes into force to SIP REFER message, " info " expression comes into force to SIP REFER message, " notify " expression comes into force to the SIP NOTIFY, and " publish " expression comes into force to the SIP PUBLISH.
The zero-time that start_time parametric representation current " interruption-free " subscribe request comes into force.After " now " expression interruption-free service control appliance 3 was accepted subscribe request, the interruption-free service came into force; The interruption-free service just came into force after " delay " expression postponed a period of time.When the start_time parameter value is " delay ", need indicate the concrete delay entry-into-force time point of interruption-free service, it can have two kinds of form SIP-date or delta-seconds, SIP-date is a kind of time format of representing hour minute second date, the concrete time point that the service of expression interruption-free comes into force; Delta-seconds be a unit for second nonnegative integer, expression postpones that the interruption-free service comes into effect after some seconds.
It should be noted that, because being provided in the sip subscribe mechanism, expression subscribes to the header field Expires of the term of validity, be used for the concluding time that expression " interruption-free " subscribe request comes into force, so in this dnd incident bag, do not define the parameter of the concluding time of representing that current " interruption-free " subscribe request comes into force.
Under which is present condition, coming into force of presence-status parametric representation current " interruption-free " subscribe request at user (user of request interruption-free service), the concrete parameter value of " token " expression can be self-defined; " all " is illustrated in all and is under the present condition and all comes into force.
The interruption-free service of available-inform parametric representation request is when cancelling, network (interruption-free service control appliance 3) unaccepted calling subscriber during the interruption-free service comes into force with proactive notification or callback, parameter value is respectively " true " and " false ", " true " expression proactive notification or callback, " false " expression is not notified or callback.This available-inform parameter has the enhancement function to traditional interruption-free service, and it provides better man-machine interface to the calling subscriber.
From the above, the msg parameter list is understood the rule that the sip message content is filtered, and in fact the value of this msg parameter is exactly " method (method) " in the sip message content.Be well known that a sip message is made up of request row (Request-Line), header field (header), message body (message body), " method " is exactly to be arranged in " request row ".
In addition, in the present invention, " header field " can be as the filtering object in the filtering rule with the content relevant with calling party's attribute in " message body ".Therefore the present invention also can be with content relevant with calling party's attribute in the sip message as filtering object, and the more more complicated filtering rules of foundation, thereby be attached in the dnd incident bag as parameter, for example this dnd incident bag can comprise further that parameter is as follows:
identity：all/null/id(caller_number)
referred?by：all/id(referred_by_number)
diversion：all/id(diversion_number)
subject：token
priority：non-urgent/normal/urgent/emergency
content_type：(media_type)
Wherein, identity parametric representation filtering object is a caller-marking in the sip message." all " expressions come into force to all caller-markings in the parameter value; " null " do not come into force when expression has caller-marking; " id " expression comes into force to concrete caller-marking, and need be provided with concrete caller-marking caller_number this moment.This moment it should be understood that this identity parameter at sip message in filtering object be exactly From header field and P_Assert_Identity header field.
Referred_by parametric representation filtering object is a reference source sign in the sip message, its at filtering object be exactly the Referred_By header field." all " signs come into force to all reference source signs in the parameter value, and " id " expression comes into force to concrete reference source sign, and concrete reference source sign referred_by_number need be set this moment.
Diversion parametric representation filtering object is the transfer party sign in the sip message when call out to take place shifting, at filtering object be exactly the History_Info header field." all " signs come into force to all transfer party signs in the parameter value, and " id " expression comes into force to concrete transfer party sign, and concrete transfer party sign diversion_number need be set this moment.
Subject parametric representation filtering object is the Subject header field in the sip message, i.e. the title of SIP session.
Priority parametric representation filtering object is the priority of SIP session, at filtering object be exactly the Priority header field.Four parameter value non-urgent (not urgent), the normal (normally) of Priority header field, the different priority of urgent (urgently), emergency (promptly) expression.
Content_type parametric representation filtering object is the medium type of sip message body, at filtering object be exactly the Content-Type header field.Need be provided with concrete medium type media_type this moment, and this parameter value is corresponding parameters value in the Content-Type header field just.
It should be noted that the parameter value of filtering object has uncertainty on data are provided with, for example reference source sign of the caller-marking of identity parameter, referred_by parameter etc.Thus when sending " interruption-free " subscribe request the user, can be easy these parameter values are set, the present invention can increase a parameter and distinguish " certain filtering object is carried out interruption-free " and " object except that certain filtering object is carried out interruption-free " both of these case in this dnd incident bag, for example in the SIP SUBSCRIBE message of initiating " interruption-free " subscribe request, the definable parameter is as follows:
Event：dnd；msg＝invite；identity＝mary@tele.com
Its expression should " interruption-free " subscribe request wish to caller-marking to be the incoming call SIP INVITE implementation interruption-free of mary@tele.com.If but the user wishes that to removing caller-marking be all incoming call SIP INVITE interruption-frees of mary@tele.con, then in order when initiating subscribe request, to distinguish both of these case, the present invention can be by in the parameter value of filtering object, increase " exception " parameter, when it is set to true, i.e. expression " is carried out interruption-free to the object except that certain filtering object ", for example:
Event：dnd；msg＝invite；identity＝mary@tele.com，exception＝true
Operation information is registered, cancelled to＜http protocol carrying interruption-free 〉
Understood specifically by definition and the value explanation of Session Initiation Protocol establishment above based on all kinds of parameters of the interruption-free filtering rule of sip message and/or time and/or user's presentation information.To illustrate that below sip terminal carries the method that operation information was registered and cancelled to interruption-free by http protocol, it generally is that embedded data by the XML language description are described the interruption-free service registration and cancelled operation information in http protocol, and the describing mode of this data structure generally can adopt XML Schema.
Realize carrying the interruption-free registration and cancelling operation information by http protocol, just must have in the above-mentioned Session Initiation Protocol of carrying the parameter in the dnd incident bag and the subscription expiration parameter of Expires header field in the http protocol, be the parameter in the dnd incident bag and subscribe to expiration parameter and all need to describe that for example the data structure to the description of aforesaid msg parameter is as follows by the XMLSchema data format:
<xsd：simpleType?name＝″msg″>
<xsd：restriction?base＝″xsd：string″>
<xsd：enumeration?value＝″all″/>
<xsd：enumeration?value＝″invite″/>
<xsd：enumeration?value＝″message″/>
Wherein, " msg " represents that promptly parameter name is msg, and data type is " string " character string, and value can be " all ", " invite ", " message " etc.
With reference to the description of the data structure of above-mentioned msg parameter, can obtain the data structure of other relevant parameter, no longer describe at this.Thereby the described interruption-free registration solicited message that HTTP message is carried has then comprised the interruption-free filtering rule based on sip message content and/or time and/or user's presentation information.
Thus, register, cancel operation information according to provided by the invention by Session Initiation Protocol (http protocol) carrying interruption-free, establishment is based on the interruption-free filtering rule of sip message content and/or time and/or user's presentation information, make all sip terminal users in the grouping telecommunications network, can directly register the interruption-free service, make the interruption-free service in the conventional telecommunications net that good inheritance arranged by the SIP interface; Than the interruption-free service function in the conventional telecommunications net very big expansion has been arranged simultaneously, except the incoming call calling, characteristics according to sip message in the packet domain, the user can create interruption-free to multiple sip messages such as instant message, subscribe message, notification message, Reference News according to self needs, protects the user to avoid bothering more completely; In addition, the sip terminal user can create the interruption-free filtering rule based on content relevant with calling party's attribute in subscriber presentation state, the sip message, makes customization that the user can be more careful go out to meet the segmentation scene of avoiding bothering of oneself needs; And, the sip terminal user can also require network behind the interruption-free service failure of its registration, notice is unaccepted calling subscriber during the interruption-free service comes into force, or finishes by the SIP session of interruption-free service-denial, provides friendly more man-machine interface to the calling subscriber.
＜interruption-free service procedure 〉
Below with reference to Fig. 1 the interruption-free service procedure that interruption-free service system 1 of the present invention realizes is specifically described.
This interruption-free service procedure comprises that mainly the user registers the interruption-free service on sip terminal 2 and interruption-free is served control appliance 3 provides application process from the interruption-free service to sip terminal 2 users.
＜registering/canceling interruption-free service 〉
Fig. 2 has shown the enrollment process according to interruption-free service of the present invention.
As shown in Figure 2, in the grouping telecommunications network that with SIP is the core net call control signalling, the user registers the interruption-free service method on sip terminal 2, comprises the steps (following is that example describes with sip terminal A):
A) user carries interruption-free registration solicited message by sip message or HTTP message on sip terminal A, sends interruption-free registration request to interruption-free service control appliance 3; And
B) interruption-free service control appliance 3 is after receiving described sip message or HTTP message, judge whether to allow current sip terminal party A-subscriber's interruption-free registration request (for example to judge whether this sip terminal party A-subscriber has the service authority of registration, whether surpass the current time registered effective time, whether conflict mutually with registered other interruption-free service request of this sip terminal party A-subscriber, whether conflict or the like mutually) with registered other business of described sip terminal, if allow, then through predetermined time-delay current sip terminal party A-subscriber's interruption-free service is come into force immediately or according to the time parameter in the described interruption-free registration solicited message.
Wherein, described interruption-free registration solicited message comprises the interruption-free filtering rule based on sip message content and/or time and/or user's presentation information.
Wherein, the concrete setting principle of this interruption-free filtering rule can be as follows:
(1) can to indicate concrete sip message content be filtering object to described interruption-free filtering rule based on the sip message content, filtering object can be the method in the request row in the sip message, as INVITE, MESSAGE, SUBSCRIBE, NOTIFY, INFO, REFER, PUBLISH, INFO etc.
In addition, sip message content as filtering object, can also be content relevant with calling party's attribute in the sip message, can be From header field content, P_Assert_Identity header field content, Referred_By header field content, History_Info header field content, Priority header field content, Subject header field content, Content_Type header field content etc.

＜provide interruption-free service-be control method 〉
Fig. 3 has shown according to of the present invention provides the interruption-free service, promptly controls the interruption-free service method.
As shown in Figure 3, it with SIP the grouping telecommunications network of core net call control signalling provides application process from the interruption-free service to sip terminal 2 users, have following steps (this sentences sip terminal A is that example describes, and the interruption-free service of this sip terminal A registration enters into force):
C) other users (for example sip terminal party B-subscriber) send the SIP conversation message by interruption-free service control appliance 3 to this sip terminal party A-subscriber, with call out this user subscribe to this user or notify this user or and this user carry out instant messaging etc.;
D) interruption-free service control appliance 3 is after receiving described SIP conversation message, the filtering rule of the current interruption-free service that comes into force of presentation information that described SIP conversation message content and/or sip terminal party A-subscriber is current and sip terminal party A-subscriber mates, judge that whether this SIP conversation message refused by the service of this sip terminal party A-subscriber's interruption-free or require input to break through the interruption-free password, wherein
If be not rejected, then interruption-free service control appliance 3 sends this SIP conversation message to this sip terminal party A-subscriber;
If be rejected, then interruption-free service control appliance is refused this SIP conversation message, returns SIP failure response sign indicating number to described sip terminal party B-subscriber;
Break through the interruption-free password if be required input, then interruption-free service control appliance 3 points out described sip terminal party B-subscriber to input password by text or voice mode, if the input password is correct, then this SIP conversation message is sent to this sip terminal party A-subscriber, otherwise refuse this SIP conversation message, return SIP failure response sign indicating number to described sip terminal party B-subscriber.
Wherein: described SIP conversation message can be SIP INVITE, SIP MESSAGE message, SIP SUBSCRIBE message, SIP NOTIFY, SIP INFO, SIP REFER message, SIP PUBLISH, SIP INFO etc.Above-mentioned SIP conversation message content can also be a content relevant with calling party's attribute in this message, as From header field content, P_Assert_Identity header field content, Referred_By header field content, History_Info header field content, Priority header field content, Subject header field content, Content_Type header field content etc.And described SIP failure response sign indicating number can be SIP 480Temporarily Unavailable answer code (temporarily can not answer code).
In step D, the current presentation information of above-mentioned sip terminal party A-subscriber can be the present condition that is of current sip terminal party A-subscriber's SOT state of termination and/or sip terminal party A-subscriber issue.At this moment, interruption-free service control appliance 3 can be in charge of the current SOT state of termination of the network node request sip terminal party A-subscriber of user terminal state and subscriber presentation state and be present condition in the grouping telecommunications network.
