Description

Public identifier management and method, managing public identity records in information transmission network Server, group public identity management equipment and computer program

The present invention relates to a kind of method of managing public identity in data transmission network.

The invention still further relates to the server of corresponding managing public identity records, the equipment of management group public identity and phase The computer program answered.

In particular it relates in internet type data transmission network, this network passes through conversation initialized protocol (session initiation protocol, SIP) sends out between network and the group's public administration equipment being connected to this network Play data transmission link.

Session Initiation Protocol has become initiates language between multiple users under Internet protocol (internet protocol, IP) environment The reference agreement of sound conversational communication.It is intended that in the framework of optional global network framework, such as those are according to some spy Calibration certainly justice, allow telecom operators by IP network for client provide speech business global network framework (as by The framework of EISI TISPAN or CableLabs definition), it is allowed to current telephone communication network (commutated telephone Networks, CTN) in known application replicated and extended.The user of SIP network can be by the phone number of regular length Code is identified, and ten telephone numbers used such as France, this mode is closed planning；Can also be by variable-length Number is identified, such as, in the zones of different of Germany, a kind of mode is Open planning；Furthermore it is also possible to use a kind It is similar to the special alphanumeric identifier of SIP mail format: URI (universal resource identifier, Uniform Resource Identifier) it is identified.

Session Initiation Protocol also allows for having each telecom operators of different types of user and different types of terminal unit Set up between network and connect.Wherein, it is worth mentioning at this point that corporate networks or IPBX (IP privatebranch exchange, IPBX) situation, namely access public operators network private company network by IP agreement, can be for being connected on corporate networks Terminal unit multiple service (such as speed dialling etc.) is provided, this is also at present to use Special Automatic little exchange in many companies The situation of machine (private automatic branchexchanges, PABX).

In the telephone network, one or more numbers in the number planning of the country that these entities are generally connected by them Section constitutes (such as, No. 123456 sections in France's number planning), and these number section itself can be regular length, such as France Situation, it is also possible to be variable-length, such as the situation of other countries.

Manager for latter event, corporate networks or IPBX is responsible for being converted into a number section son section, alternatively, son Number section can have different length.

So, this network is transparent for this tissue, no matter no matter how and this number is the length of this number No meet the length of son section belonging to it, all arbitrarily calling can be directed to certain number of certain number section of corporate networks or IPBX Code.

Session Initiation Protocol double mark concepts based on user:

-the first mark, hereinafter referred to as public identifier (also referred to as address record), user can be related to based on this mark (such as telephone number, or the alphanumeric sequence of forename.surname@domain type)；

-the second mark, hereinafter referred to as contact, with address (also referred to as contact address), represent the physics that can relate to this user The network address (such as, the IP address of user terminal).

Incidence relation between one public identifier and (or multiple) contact address can change over time.At a quilt It is referred to as the stage of registration phase, it is allowed to user is by the incidence relation between its public identifier and one or more contact address, logical Know to network, especially, notify to the entity being used for managing users registration state (referred to as " REGISTRAR ") in network.

This incidence relation will be stored in corresponding in the location database in the location server of this network subsequently, and this counts According to storehouse for according to pointing to the incoming call request of user's (this user is identified) with his public identifier to search be associated Individual or multiple contact addresses, this incoming call request will be forwarded to this contact address found.

The process realizing this login mechanism with Session Initiation Protocol is as described below:

User agent (user agent, UA) to " REGISTRAR " transmission " REGISTER " registration message of its correspondence, with It is registered to network." To " header being somebody's turn to do in " REGISTER " registration message comprises the public identifier being registered, " Contact " header Comprise the physical address (such as, its IP address) of its contact address, i.e. corresponding device.Receive this " REGISTER " registration to disappear During breath, " REGISTRAR " records above-mentioned information in location database, and responds one and accept message (" 200OK ").This message Terminate this SIP registration stage.

(from " REGISTER " to " 200OK ") during a SIP registration, allow registration many for a public identifier Individual contact address associated therewith.On the other hand, the most clearly, can not be registered by SIP signaling and contact with same The associated plurality of public entities in address.

Therefore, multiple public entities to be registered, it is necessary to through at least suitable with the public identifier quantity being registered quantity Priori (priori) initialize registration.

Such as, it is connected to public network for one by Session Initiation Protocol and respectively distributes independent public affairs for multiple users Altogether for the IPBX of entity, this IPBX sends the quantity of " REGISTER " registration message, it is necessary to can visit from public network with needs The quantity of the public identifier asked is identical.

IP Multimedia System (IP multimediasubsystem, the IMS) frame defined by 3GPP and ETSI TISPAN Structure, under given conditions, in the single SIP registration stage, it is allowed to register single with what multiple public identifiers were associated It is address, thus improves above-mentioned mechanism.It practice, this framework is that (this data base is referred to as ownership and uses by customer data base Family server, home subscriberserver, HSS) support, store in this data base customized in each user The set of public identifier.So, in multiple public identifiers of a user, one or more marks of default registration can be defined Know set, i.e. when user clearly register during SIP registration in this logo collection a certain mark time, then this or The set of multiple marks will be registered automatically by SIP network.Therefore, in registration process, the identification sets being associated with this mark The default registration closed occurs at the initial phase of this network, and user also can only revise the customization that his operator provides, and nothing Method carries out other operation.

The common feature of the enhancement mode login mechanism defined in above-mentioned login mechanism and IMS System Framework is, registration The storage of the public identifier in location database is independent and detailed.

According to the fundamental mechanism in definition Session Initiation Protocol, when one " UA " wishes to register multiple public identifier simultaneously, it is worked as Shi Bixu initiates the registration process identical with the physical quantities being registered.Therefore, this defect can because by mutual message with And the process of correspondence and cause network load overweight, consequently, it is possible to cause occur network congestion probability increase.

It addition, registration typically occurs in initialization (or reinitializing) stage of " UA ", and must carry out periodically brushing Newly.But, network reinitialize due to such after going wrong it may happen that, send a large amount of after following network problem closely Message also leads to this network problem and more deteriorates.

Finally, the result to the registration delays of all users, will also result in non-registered users and cannot receive or send calling Problem.

The mechanism supported of IMS architectural framework defining default registration mark overcomes these defects, because wall scroll " REGISTER " message just be enough to register multiple public identifier.On the other hand, this requires to belong to group's note to each in network The mark of volume carries out priori statement (prior delcaration), and these marks is stored in location database.

This is for the IPBX network being assigned Telo-Jumbo section or corporate networks, is not exclusively to be suitable for , because this requires that number section of this organization internal is visible to public network, and also need to a great Rong that can store individual's section Amount storage.

And this also can introduce the processing procedure of complexity, in order to the manager because of corporate networks or IPBX at any time His in-house section is changed (increase, delete number etc.) and with the data of public network required for carry out same Step.

When the user of corporate networks uses SIP form: URI (such as SIP:terminalX@YYYYYY.com, wherein X Span is 0 to 100) when representing, the problems referred to above equally exist.It should be noted that the public affairs wishing to increase its terminal quantity Department, it is necessary to contact it and connect operator to revise its default registration parameter.

The number that the form transmission user that switched telephone network (CTN) is continued by a kind of message dials, wherein every disappears Breath all comprises dialled the number partial sequence.This " overlaps " formula mechanism and is commonly used to dialed number and belongs to open rule Draw the situation of (i.e. number length is variable).In the framework of IMS type structure, refusal is only comprised portion numbers sequence by network The request of incoming call, its mode and this number sequence belong to the processing mode phase in the case of unallocated number (the most unregistered) With.This is owing to the most complete number could be registered on the sip network, and requires that SIP network existence can detect overlapping The go-between up-link of numbering, and can be from the imperfect sequence received before submitting message to SIP network Reconstruct number.

Present invention aim to address these problems above-mentioned.

To this end, subject of the present invention is a kind of in network and group's public administration equipment (10) being connected to this network Between initiate the method for data transmission link, it is characterised in that include step:

-preparation definition and registration step, define and register described group public identity, and this group public identity represents at least One group by the multiple independent public entities of described group public administration equipment control；

The request step of incoming call is initiated in-checking, verifies the number sequence that the request of described initiation incoming call is comprised The most corresponding registered group public identity of row；

-send request step, send the request of described initiation incoming call to a contact address, described contact address is corresponding In described registered group public identity.

The method can also include one or more following feature:

-described preparation definition is additionally included in defined in a group with registration step and associates the plurality of independent public entities Rule, and described checking initiate incoming call request step, including verify described number sequence described in whether meeting the most fixed The correlation rule of justice；

-described preparation and definition step are additionally included in the location database (13) of described network (11) registers described group Public identifier；

-described group public identity is associated with the identification information of the group's general identifications in described location database；

-described group general identifications is made up of the common ground of each independent public entities in described group.

According to a further aspect in the invention, described contact address is corresponding, described with described group public administration equipment After equipment receives the request of described initiation incoming call, described method also comprises the steps:

-analytical procedure, extracts corresponding independent public identifier by described group public administration equipment；

-routing step, when described number sequence is complete, routes to relative with described independent public identifier by described request The receiver answered, described independent public identifier is extracted by described equipment (10), and connected；And

-send messages step of makeing mistakes, when described number sequence is imperfect, send a message extremely described network, with instruction Described number sequence is imperfect.

So, this request is routed to be responsible for the equipment of group's general identifications by this network, and, the latter is to this mark Perform an integrity analysis step, thus from this mark, extract the independent public identifier of correspondence, then these data are route To the corresponding receiver being connected with this equipment.If this number is imperfect, it indicates that the incomplete error messages of number will Can be transferred out by network, include the complete number of remaining digit to ask calling terminal to send, these remaining digits originally should Transferred to when dialing by calling subscriber.

The invention still further relates to a kind of in internet type information transmission network for managing the equipment of group public identity, Use Session Initiation Protocol to initiate data transmission link between described equipment and described network, it is characterised in that it includes:

The device of-the transmission request in order to register a group public identity, described group public identity represents least one set The multiple independent public entities being stored in a location database, described location database manages server with group public identity Being connected, described server is associated with described network (11)；

-to initiating the device that is analyzed of request of incoming call, described request comprises one and is registered in described position data Group public identity in storehouse, this analytical equipment is for extracting the independent public identifier of correspondence；

And this device also includes:

-route device, for when described number sequence is complete, routes to described request and described independent public identifier Corresponding receiver, described independent public identifier is extracted by described group public identity management equipment, and connected； And

-send information apparatus of makeing mistakes, for when described number sequence is imperfect, send a message extremely described network, with Indicate described number sequence imperfect.

According to a further aspect in the invention, present subject matter further relate to a kind of in internet type information transmission network for The server of management group public identity, uses SIP between the management equipment (10) of described network and a group public identity Agreement is to initiate data transmission link, and described server is connected with location database (13), it is characterised in that described server Including:

-definition and register device, be used for defining and registering a group public identity, and described group public identity represents at least One group of multiple independent public entities managed by described management equipment (10)；

The device of the request of incoming call is initiated in-checking, and the request of described initiation incoming call comprises a number sequence, uses In verifying that described number sequence is whether corresponding with a registered group public identity in described location database；And

-send request unit, for sending the request of described initiation incoming call to a contact address, described contact address Corresponding with described registered group public identity.

According to a further aspect in the invention, subject of the present invention includes that one can be downloaded from communication network and/or be stored in On computer-readable medium and/or the executable computer program of microprocessor of registration management server, its feature Being, it comprises and realizes the code instructions that the method according to the invention is relevant for performing.

Finally, the present invention relates to one can from communication network download and/or be stored in computer-readable medium and/ Or group public identity management equipment the executable computer program of microprocessor, its feature is, it comprise for Perform to realize the code instructions that the method according to the invention is relevant.

Therefore, the present invention passes through unique " REGISTER " message, with the form registration one of " regular " definition group The set (may be the biggest) of individual public identifier, and each mark constituting logo collection is stored respectively without network, thus gram Take the defect existing for two kinds of register methods of the prior art.

The registration of group rules makes user's (such as corporate networks) can be without stating each that be associated respectively Carry out in the case of public identifier terminating calling.The most well-regulated amendment dynamically can be carried out by signaling.

It addition, the request that the invention enables SIP network route to initiate incoming call is possibly realized, this initiation incoming call Request comprises portion numbers sequence, but meets one of rule of being stored in SIP network.It is advantageous that, receive this and comprise not The entity of the request initiating incoming call of complete number sequence, is the entity managing these numbers.This entity is the most permissible Send error messages to calling party, to indicate number imperfect (" 484 addresses are imperfect " message), thus send an invitation to ask Ask calling party to send the complete number including remaining digit, and these remaining digits should be transferred to when dialing by calling party originally. Without method provided by the present invention, it is unallocated that what calling party received is designated as number, and this instruction is by this calling of termination.

The method according to the invention, it is allowed to registering in SIP network with the form of group definition rule, this rule is wrapped Include the set of a non-deterministic mark, and these marks are the most individually by known to this network.One direct applied example is, Registration in the carrier network of corporate networks or IPBX network, these corporate networks or IPBX network are allocated one or many Individual variable-length section, needs to process the incoming call request comprising imperfect number sequence simultaneously on the sip network.

If with reference to appended schematic figures, then can be best understood from the present invention, wherein:

-Fig. 1 shows register method and the structure of system, the merit of the independent identification of SIP:URI type in the prior art Can block diagram；

-Fig. 2 show according to the present invention realize in order to register group definition rule the structure of method and system, function Block diagram；And

-Fig. 3 shows and calls the block diagram being route in a system according to the present invention when number section is imperfect.

As it was previously stated, the present invention relates to a kind of side for managing public identity in internet type information transmission network Method, uses Session Initiation Protocol to initiate data transmission at described network and the group identification management equipment room being connected with this network Link.

In the prior art, the realization of the login mechanism of Session Initiation Protocol is as described in Figure 1.

According to this login mechanism, the user agent " UA " that in figure, label 1 represents, represented by transmission label 3 " REGISTER " registration message, to " REGISTRAR " that represent with label 4, is registered to the network represented with label 2, wherein " REGISTRAR " is actually associated with a location server, this location server itself and the positional number by label 5 mark It is connected according to storehouse.

" To " header of " REGISTER " registration message 3 comprises the public identifier that will be registered, " Contact " header, it Contact address, corresponding to the physical address of equipment, such as its IP address.When receiving " REGISTER " registration message, " REGISTRAR " checks this information in location database 5, and what then response label 6 identified accepts message (" 200OK "), Thus terminate the SIP registration stage.

As it was previously stated, in single SIP registration (" REGISTER "-" 200OK "), multiple pass can be registered and is coupled to same The contact address of public identifier.On the other hand, it is impossible to by SIP signal, register the public affairs that multiple and same contact address is associated Entity altogether.

Therefore, multiple public entities to be registered and have to pass through at least suitable with public identifier quantity need to be registered number-of-registration Priori (priori) initialize.

These problems of solution are the invention enables to be possibly realized.

Therefore, although Session Initiation Protocol only allows user agent " UA ", in its registration request, (this mark can estimate one and be correlated with The collection of mark of connection and be registered simultaneously) transmit an independent public identifier, but in the method according to the invention and system, one Individual " UA " includes a group definition rule, or a pointer pointing to the good rule of configured in advance on network, so exists In its registration request, use this rule can register the set of a uncertain mark, thus formed one include multiple solely The group of vertical public identifier.Thus, it can be assumed that different rules, such as, all numbers initiate with " 12345 ", or " all 7 to The number of 10 initiates with " 12345 " ", or the sequence of QWERTY keyboard (qwerty) character " all marks comprise ".

Subsequently, when the request receiving incoming call, this mechanism is possible not only to judge whether public identifier is included in this position Put in data base, thus the contact address that the request obtaining this incoming call will be forwarded to, it is also possible to check (such as position clothes Business device) this identifies whether one of rule following earlier registration.Subsequently, the request of this incoming call is sent to being met with it One or more contact addresses of being associated of each rule.

Register a type as follows as an embodiment of the rule of " URI of all SIP: User Part initiates with xyz ":

-reuse " REGISTER " message carry rule registration request,

-reuse " To " header and carry rule to be registered, or point to the pointer of this rule,

-it is used behind asterisk wildcard at xyz character, as "<*>" indicates this can be any number of any character,

-definition one new SIP:URI parameter (such as " regular ") indicates this SIP:URI, and wherein User Part comprises One rule, and character "<*>" must be construed to asterisk wildcard,

-this regular is stored in same position data base with independent public identifier.

This registration request can represent by following form:

REGISTER...

To:sip:xyz<*>@domain；rule.

In order to use more complicated rule, it may be considered that with enhancement mode Backus normal form (BNF) (augmentedBackus-Naur Form, ABNF) rule presenting set defined in grammer, this is also used to indicate that the grammer of Session Initiation Protocol.

Another thes improvement is that, for indicating parameter that this registration request comprises a rule or any other information, Can also indicate that the grammer expressing this rule.

Fig. 2 shows the flow chart of a complete registration rule, and an example of this rule is defined as " all phones Number, with+1234 beginnings, is followed by other 4-digit number (between 0～9) ".This rule can be according to enhancement mode Ba Ke This normal form (ABNF) is described as follows: "+1234 "<*>4DIGIT.Therefore, this rule can be by containing " To " territory " REGISTER " message is registered, the ABNF syntactic description of this rule.Represent the grammer of this rule by new parameter " rule= RFC2234 " represent.

Therefore:

REGISTER... To: sip::″+1234″ *4DIGIT@orange.com；User=phone；Rule= RFC2234.

In fig. 2, it can be seen that group's public administration equipment, represent with label 10 in the drawings, such as, by IPBX structure Become.

This IPBX, such as, is connected to the position represented with label 12 by the information transmission network 11 of an Internet type Server, this location server is connected with the location database represented with label 13.

Registration message " REGISTER " represents with label 14, accepts message (" 200OK ") and represents with label 15.

Therefore, according to the management method of the present invention, including the step for defining and register a group public identity, this group Group public identifier represents at least one group being made up of multiple independent public entities, and the plurality of public entities is by being connected to network Group's public administration equipment, such as terminal 10, is managed.

It practice, the definition of group public identity is the definition of the group associations rule of the plurality of independent public identifier, The registration of this group public identity is included on the location database of the location server being associated with this network registration the latter.

This group public identity is associated with the mark data as group's general identifications subsequently in location database, This group's general identifications can the common ground composition of multiple independent public identifiers in this group.

When receiving public identifier by network, server can verify that receive identifies whether corresponding to being stored in Certain group identification in location server.

Therefore, as it is shown on figure 3, the present invention also allow for SIP network to initiate incoming call request route, described please Ask and comprise portion numbers sequence, but this sequence meets one of storage rule on the sip network.It is advantageous that, receive this bag The entity of the request initiating calling containing imperfect number, is the entity managing these numbers.Then this entity can send One error messages is to calling party, to point out number imperfect (such as, " 484 addresses are imperfect " message), thus please to calling party Ask and send the complete number including remaining digit, and these remaining digits should be transferred to when dialing by calling party originally.

Fig. 3 indicates the different messages of (1) to (11), illustrates at network, server 12 and location database 13, IPBX Message exchange different between 10 and corresponding receiver, the latter represents with label 16.

It can thus be seen that data are routed to manage the equipment of group public identity by network, the latter is by this mark Carry out the step of integrity analysis, therefrom to obtain corresponding independent public identifier, and by these data and this call routing to one Corresponding receiver, this receiver is connected with this equipment, and by this equipment control.

Owing to these different messages exchanged are known type, below will no longer they be described in detail.

The method and this system can be realized by computerized mode, as comprised the computer program of code command, When executed, the programs, can define and register a group public identity, this group public identity represents least one set in interconnection Multiple independent public entities in the information transmission network of net type, this network is by Session Initiation Protocol at this network and with this network even Data transmission link is initiated between the group public identity management equipment connect.

It practice, the method according to the invention depends on the bearing capacity between " UA " and its SIP " REGISTRAR ", For registering the request of a rule, the group that this rule is represented by a general public identifier of group for definition, at one Put and data base stores aforementioned rule and the ability of the one or more contact addresses being associated, and receiving the incoming call request phase Between, the purpose public identifier that the ability of the location database of inquiry storage aforementioned rule and checking receive in this request is The no ability meeting one of registered rule.

Certainly, other embodiments of the present invention are also that those skilled in the art are readily contemplated by one that.
