Description
Technical field
The present invention relates to the network communications technology field, be specifically related to a kind of method and device for business processing of dialogue-based initiation protocol.
Background technology
SIP (Session Initiation Protocol, Session initiation Protocol) is the IP phone signaling protocol that is proposed by IETF (Interne engineering duty group).Implication as its name surface, SIP is used for initiation session, it can control the foundation and the termination process of the Multimedia session of one or more participant's participation, and can dynamically adjust and revise session attribute, as session bandwidth require, the medium type of transmission such as voice, video, text etc., medium code/decode format, to the support of multicast and clean culture etc.
SIP provides necessary protocol to provide following business to guarantee terminal system and acting server: the user location; User capability; User availability; Call setup; Call treatment; Comprise equivalent 800 types calling, no-answer call connection, call forwarding on busy, the Call Forwarding of mode such as unconditioned call connection; Call number is transmitted, and call number wherein can be to adopt the call number transmission of any naming mechanism name; Personal mobility is as arriving the called party by an address single, location independent, even the called party has changed terminal; The negotiation of terminal type and selection, promptly the caller can provide selection and how arrive the other side, as passing through Internet telephony, mobile phone or answering service etc.; Terminal capability negotiation; Caller and callee's authentication; Ignorant and instruct the calling transfer of formula; The invitation of multi-cast conferencing etc.
The protocol that SIP provides comprises: name translation and user location, and promptly where the called party guarantees to call out the arrival callee, carries out the mapping of any descriptor to locating information, guarantees that the essential details of call/session is supported; Feature negotiation, because not all side can both support the feature of same levels, so, allow and call out relevant group comprise that the group of Multi-Way Calling reaches an agreement on the feature of support; Call out participant's management, promptly the participant can introduce other user and adds and call out or cancel connection to other user in calling, and in addition, the user can be transferred or be changed to call out and keep; Call features changes, be that the user should be able to change the call features in the calling procedure, can be set to " voice-only " as a calling, but, in calling procedure, the user can open video capability according to actual needs, that is to say that a third party who adds calling can open different features in order to add this calling.
Development along with broadband network, mobile communication will not only be confined to traditional Speech Communication, multimedia service in conjunction with multiple medium types such as audio frequency, video, picture and texts will be carried out gradually, by with presence (presenting business), management and group, the combination of data services such as short message, WEB (webpage) browse, locating information, PUSH (pushing professional), file-sharing can be satisfied user's multiple demand.
Under the promotion of multiple application, normal structure such as 3GPP and 3GPP2 has all successively been released IP-based IP multimedia subsystem, IMS framework, purpose is to use a kind of structure of standardized opening to realize diversified multimedia application in the mobile network, and the user is more to be selected and abundanter impression to offer.
In 3GPP Release 5 (R5) stage, introduced IMS domain, be called for short IMS, IMS is superimposed upon on the packet field network, be made up of CSCF (CSCF), MGCF (MGCF), MRF (media resource function) and HSS functional entitys such as (home signature user servers), wherein: CSCF can be divided into S-CSCF (serving CSCF), P-CSCF (proxy CSCF) and three logic entities of I-CSCF (inquiry CSCF) again.S-CSCF is the service switching center of IMS, carries out session control, and peace preservation association's speech phase is in charge of user profile, produces charge information etc.; P-CSCF is the access point of terminal user access to IMS, finishes user's registration, is responsible for QoS control and safety management etc., and I-CSCF is responsible for the intercommunication between the IMS territory, and network topology and configuration are externally hidden in the distribution of management S-CSCF, produce metering data etc.The MGCF control gateway realizes the intercommunication of IMS network and other network, and MRF provides media resource, as the folding and unfolding sound, and encoding and decoding and multimedia conferencing bridge etc.HSS (home signature user server) is a customer data base, storage IMS user's subscription data and configuration information etc.
Because it is irrelevant that the structure of IMS network has been accomplished with the bottom bearer network, therefore, the IMS network of 3GPP definition also can be applied on other packet networks outside the packet field network of 3GPP definition, such as the packet network that defines among the 3GPP2, wlan network and NGN network etc., realized with the user use terminal type independence and and the independence of access network type, therefore, here do not limit IMS and only be applied in relevant network of 3GPP and the application, the access network of other types and the business of bearer network and application also can realize with the IMS framework.
The user of each IMS business of having contracted has distributed one or more private user identity IMPI by home network operator, be used for using at registration, mandate, management and charging process, IMPI uses NAI (Network Access Identifier, network access Identifier) form, each IMS user also has one or more public user identity IMPU, sign oneself finds the other side when being used for other telex networks.Private user identity is generally externally not open, and public user identity is externally disclosed, uses in the conversation procedure that uses all kinds of business.The MSISDN that uses in the available circuit switching network can continue to use in the IMS network, and can be considered as is a kind of special public user identity.
HSS is the most important database of each user, in store all with signatory relevant information, be used to support the processing of each network entity to calling and session, the information of its preservation comprises: user ID, numbering and addressing information, user security information, customer position information and user description information (user profileinformation) etc.A home network can have one or more HSS, and the quantity of HSS depends on the capacity of mobile contracted user's quantity, the network equipment and concrete networking situation.Between a plurality of entities in HSS and the network interface is arranged.
In IMS, Session Initiation Protocol is used as the signaling control protocol of IP multimedia session and sets up, revises and delete IP multimedia session, satisfies the demand of user to multimedia communication.The IMS network is compared with common SIP network, an outstanding feature is exactly: the IMS network will be one can run manageable carrier class network, contracted the user of IMS Network by paying certain expense, can obtain the professional skill that service quality guarantees, enjoy other value-added services that operator provides simultaneously.
At present, the logical identifier IMPI and the IMPU that are used for identifying user in the IMS network come the user of each IMS subscription is carried out service management, like this, the user is after having lost the terminal equipment of oneself, network side can limit other people and use this user logic identifier to realize business, but, because network side can't determine whether this terminal equipment is used by legal users, so, any people who obtains this terminal equipment can use this terminal equipment and need not pay any cost, this loss can't be avoided for the user of the IMS network service of having contracted, and can cause the discontented of user, also is a resistance for carrying out the IMS business.
More seriously, more or less all can preserve some user profile in the terminal equipment, dispose ISIM/USIM (IMS SIM on the terminal equipment as the IMS network, the service identification module of in the IMS network, using/general contracted user's identification module), preserve the user among the ISIM/USIM and be used for IMPI (private user identity), the IMPU information such as (public user identity) of authentication, network side can't limit other people and obtain these information and use from terminal equipment, thereby, can the fail safe of telex network be impacted.
Consider multiple access technology and the phenomenon of depositing, terminal equipment is just towards the direction evolution of multimode, a terminal equipment can use different access waies to be linked on the business of IMS network in different access networks, only carry out the maintenance that Business Processing can not satisfy operator according to logical identifier, managerial demand, do not allow two terminal equipment repeated registrations as network side, but allow a multi-mode terminal equipment to register simultaneously, when supporting the multi-mode terminal equipment roaming of plurality of access modes, network side can't determine it is two terminal equipment repeated registrations according to the user logic sign, and still a multimode terminal is registered simultaneously.
Consider the easy to use of user and custom in the IMS network, allow a user on a plurality of terminal equipments, to use same public user identity, the user can select to use one of them terminal to come to set up session with the other side according to actual conditions, but because the ability that these a plurality of terminal equipments can be supported is likely different, therefore having selected a terminal equipment just means and has selected the limit of power that subsequent session can be supported, if it is improper to select, follow-up session exerts an influence to communicating pair in meeting, and according to the realization mechanism of present SIP standard, the selection that can only communicate according to logical identifiers such as public user identity or private user identity, thereby, make the IMS network have blindness and limitation to the support of multi-terminal equipment.
In sum, Session Initiation Protocol can't satisfy the requirement of IMS network carrier-class to a certain extent as being a kind of agreement of Internet service.

When SIP Server when terminal equipment is realized by SIP UA being terminal equipment distributing terminals equipment identification information in the business procedure, SIP Server can be issued to SIP UA on the terminal equipment by sip message together with the identification information of this terminal equipment and professional distant terminal equipment mark information, makes SIP UA carry out related service according to professional both sides' Terminal Equipment Identifier information and handles.
When terminal equipment need be realized business by SIP UA, SIP UA can be with SIP node such as the SIP Server of Terminal Equipment Identifier message transmission to network side, SIP UA can obtain Terminal Equipment Identifier information and transmit it to SIP Server from himself solidifying the canned data, also can be with its Terminal Equipment Identifier message transmission that obtains from the sip message that receives to SIP Server.The sip message here is that other SIP node transmission comes other SIP node such as SIP Server, other SIP UA etc.
SIP UA on the terminal equipment is except to the SIP of network side node transmits the identification information of himself, can also be with professional distant terminal equipment mark message transmission to network side, be about to calling and called Terminal Equipment Identifier message transmission to SIP Server, make SIP Server also can carry out related service and handle according to professional both sides' Terminal Equipment Identifier information.
SIP UA can be by sip message with himself and/or the distant terminal equipment mark message transmission SIP Server to network side.
SIP Server be terminal equipment distributing terminals equipment identification information, and SIP UA and SIP Server, various SIP UA between the transmission terminal equipment identification information go forward side by side the method for line correlation service optimization processing as accompanying drawing 1 to shown in the accompanying drawing 4.
Among Fig. 1, SIP UA on the terminal equipment sends Terminal Equipment Identifier information to be responsible for managing business in the SIP network SIP Server by sip request message, SIP Server obtains Terminal Equipment Identifier information from sip request message, and utilizes Terminal Equipment Identifier information that the business of SIP UA request is optimized processing.
SIP Server sends the SIP response message according to service processing result to SIP UA, and SIP UA carries out corresponding service processing according to the service processing result in the response message of Terminal Equipment Identifier information and reception thereof to the business of terminal equipment request.
Among Fig. 2, SIP Server is responsible for terminal equipment distributing terminals equipment identification information, SIP Server transfers to SIP UA with its identification information for the terminal equipment distribution by sip request message, this sip request message can be that SIP Server oneself produces, it also can be sip request message from other SIP UA, receive the sip request message that other SIP UA transmission comes as SIP Server, and this message handled accordingly as revising message content etc., then, send to SIP UA among Fig. 2.After SIP UA receives sip request message, send the SIP response message to SIP Server.Like this, terminal equipment is follow-up need carry out business by SIP UA the time, SIP UA can carry the Terminal Equipment Identifier information of SIP Server for its distribution in business request information, SIP Server and SIP UA all can utilize this Terminal Equipment Identifier information to carry out service optimization and handle.
Above-mentioned description to Fig. 2 is a Terminal Equipment Identifier information distribution process, flow process among Fig. 2 also can be described as: SIP Server transfers to SIP UA with its identification information and/or professional distant terminal equipment mark information for the terminal equipment distribution by sip request message, after SIP UA receives sip request message, send the SIP response message to SIP Server.Like this, in follow-up business realizing process, SIP UA can carry Terminal Equipment Identifier information and/or the professional distant terminal equipment mark information of SIP Server for its distribution in business request information, be calling and called Terminal Equipment Identifier information, make SIP Server and SIP UA all can utilize calling and called Terminal Equipment Identifier information to carry out service optimization and handle.
Among Fig. 3, SIP Server transfers to SIP UA with the response message of its Terminal Equipment Identifier information of distributing for terminal equipment by this request message after receiving the sip request message that SIP UA sends.Like this, in follow-up business realizing process, SIP UA can carry the Terminal Equipment Identifier information of SIP Server for its distribution in service message, makes SIP Server and SIP UA all can utilize this Terminal Equipment Identifier information to carry out service optimization and handles.
Above-mentioned description to Fig. 3 is a Terminal Equipment Identifier information distribution process, flow process among Fig. 3 also can be described as: SIP Server transfers to SIP UA for identification information and/or professional distant terminal equipment mark information that terminal equipment distributes by the SIP response message with it after receiving the sip request message that SIP UA sends.Like this, in follow-up business realizing process, SIP UA can carry Terminal Equipment Identifier information and the professional distant terminal equipment mark information of SIPServer for its distribution in service message, be calling and called Terminal Equipment Identifier information, make SIP Server and SIP UA all can utilize calling and called Terminal Equipment Identifier information to carry out service optimization and handle.
Between SIP UA and SIP Server, need transmission, know and use Terminal Equipment Identifier information to carry out the service optimization processing, under some application scenarios, equipment identification information can also transmit between different SIPUA, preserve the industry affair optimization process of going forward side by side, specifically as shown in Figure 4.
Among Fig. 4, SIP UA1 Terminal Equipment Identifier information-bearing that it is corresponding is in sip request message, and to SIP UA2, here, SIP Server can not need the identification terminal equipment identification information by SIP Server transparent transmission.SIP UA2 also can it is corresponding the Terminal Equipment Identifier information-bearing in the SIP response message, to SIP UA1, here, SIP Server can not need the identification terminal equipment identification information equally by SIP Server transparent transmission.By said process, SIP UA1 and SIP UA2 all can obtain calling and called Terminal Equipment Identifier information, and all utilize calling and called Terminal Equipment Identifier information to carry out service optimization and handle.
In the description of above-mentioned each process, sip request message, SIP response message can be registration message, and the OPTIONS response message is created the request and the response message of dialogue, as INVITE etc.
By foregoing description as can be known, the present invention can by sip message with Terminal Equipment Identifier information between SIPUA and SIP Server, perhaps between various SIP UA, transmit, preserve and use, with auxiliary, optimize the Business Processing process.
Method by sip message transmission terminal equipment identification information mainly contains following two kinds:
Method one, utilize in the sip message the new information field of increase to carry and the transmission terminal equipment identification information.
Describe with the method that in the Contact header field of sip message, increases new information field promptly to increase new parameter be example sip message carrying, transmission terminal equipment identification information below.
The present invention need increase a new feature tag (featuretag) in the Contact header field of SIP standard, this feature tag indicating terminal equipment identification information, and this feature tag can similarly be defined as: sip.device_id.
This feature tag can directly carry concrete Terminal Equipment Identifier symbol, as being used for marking terminal equipment mark information according to certain rule unified distribution in the SIP network; Also the type of carried terminal equipment identification information and concrete Terminal Equipment Identifier accord with this feature tag simultaneously.This feature tag also can the indicating terminal device identifier a part, another part can be an original loaded information in the Contact header field, as public user identity etc.
Feature tag can use character string to represent, is any type as at first clear and definite indicating terminal device identification, secondly, further indicates concrete Terminal Equipment Identifier symbol.
Typical Terminal Equipment Identifier type can have multiple, and promptly the value of Terminal Equipment Identifier type comprises: MAC, IMEI, MEID etc.Certainly, the Terminal Equipment Identifier type is not limited to above-mentioned three kinds, if occur the terminal equipment of other type later on, the corresponding increase of the value of Terminal Equipment Identifier type gets final product.
After the value of Terminal Equipment Identifier type is determined, needing to determine concrete Terminal Equipment Identifier symbol, is IMEI as the type of Terminal Equipment Identifier information, and then the Terminal Equipment Identifier of back symbol is exactly the IMEI value of preserving in the terminal equipment of this SIP UA correspondence; The Terminal Equipment Identifier type is MAC for another example, and then the Terminal Equipment Identifier of back symbol is exactly the MAC Address of preserving on this SIP UA counterpart terminal equipment.
Terminal Equipment Identifier type and the concrete manifestation form of Terminal Equipment Identifier symbol in Contact header field have multiple, illustrate for several concrete examples below:
The message format that Terminal Equipment Identifier type and Terminal Equipment Identifier symbol is separately represented in example 1, the Contact header field is as follows:
Contact:<sip:user@example.com>;audio;video;mobility="mobile";
+message="TRUE";device_id="IMEI";imei="350112408932969";
methods="INVITE,OPTIONS,BYE,CANCEL,ACK";schemes="sip,http"
Wherein: feature tag newly-increased in the Contact header field is: device_id, the Terminal Equipment Identifier type is: IMEI, concrete Terminal Equipment Identifier symbol is: 350112408932969.The Terminal Equipment Identifier symbol here can have oneself independently nomenclature principle, also can adopt existing name.
Above-mentioned message format can be converted into following asserting:
(&(audio=TRUE)
(video=TRUE)
(sip.mobility=mobile)
(message=TRUE)
(|(sip.identifier=IMEI)(sip.identifier.imei=350112408932969))
(|(sip.methods=INVITE)(sip.methods=OPTIONS)(sip.methods=BYE)
(sip.methods=CANCEL)(sip.methods=ACK))
(|(sip.schemes=sip)(sip.schemes=http)))
The message format that Terminal Equipment Identifier type and Terminal Equipment Identifier symbol is put together in example 2, the Contact header field is:
Contact:<sip:user@example.com>;audio;video;mobility="mobile";
+message="TRUE";device_id="IMEI:350112408932969";
methods="INVITE,OPTIONS,BYE,CANCEL,ACK";schemes="sip,http"
Wherein: feature tag newly-increased in the Contact header field is: device_id, the Terminal Equipment Identifier type is: IMEI, concrete Terminal Equipment Identifier symbol is: 350112408932969.The Terminal Equipment Identifier symbol here can have oneself independently nomenclature principle, also can adopt existing name.
The message format that the Terminal Equipment Identifier symbol only is set in example 3, the Contact header field is:
Contact:<sip:user@example.com>;audio;video;mobility="mobile";
+message="TRUE";device_id="00-20-ed-aa-49-e8";
methods="INVITE,OPTIONS,BYE,CANCEL,ACK";schemes="sip,http"
Wherein: feature tag newly-increased in the Contact header field is: device_id, the Terminal Equipment Identifier symbol is: 00-20-ed-aa-49-e8.The Terminal Equipment Identifier symbol here should have oneself independently nomenclature principle.
The message format that the Terminal Equipment Identifier symbol only is set in example 4, the Contact header field is:
Contact:<sip:user@example.com>;audio;video;mobility="mobile";
+message="TRUE";device_id="03";
methods="INVITE,OPTIONS,BYE,CANCEL,ACK";schemes="sip,http"
Wherein: feature tag newly-increased in the Contact header field is: device_id, the content in the feature tag is the part of Terminal Equipment Identifier symbol, grades as latter half or first half or pars intermedia.This Terminal Equipment Identifier symbol can be made of the index value of public user identity such as IMPU or MSISDN and terminal equipment, and this Terminal Equipment Identifier accords with the some terminal equipments in the terminal equipment that can distinguish several shared public user identity.Terminal Equipment Identifier symbol in the example 4 is to be made of jointly the index value among IMPU that carries among the contact and the device_id, and promptly the Terminal Equipment Identifier symbol is sip:user@example.com:03, and wherein, index value has oneself independently nomenclature principle.Because what insert here is character string, and two position indexes can represent 0～99 these 100 different numerical value, and therefore, this example can be distinguished 100 different terminal equipments under the same IMPU.IMPU and index value combine a plurality of terminals of just using a shared IMPU who can user of unique identification has.
Behind Contact header field, the SIP node can use in the present SIP network transfer mechanism of Contact header field is realized the Terminal Equipment Identifier transmission of Information with the Terminal Equipment Identifier information setting.
Example 5: reuse existing UUID NameSpace, use UUID to come terminal equipment of unique identification, specifically can be: device_id="＜urn:uuid:f81d4fae-7dec-11d0-a765-00a0c91e6bf6〉".
Certainly, the building method of Terminal Equipment Identifier information and the method that increases new information field carrying transmission terminal equipment identification information in SIP are not limited to the above-mentioned form that exemplifies among the present invention.
In method one, the Terminal Equipment Identifier information of carrying in the new information field of sip message can be for the calling terminal equipment identification information, can be the terminal called identification information, also calling terminal equipment identification information and terminal called identification information can be carried in the new information field simultaneously.
Method two, utilize in the sip message existing information territory to carry and the transmission terminal equipment identification information, promptly existing information territory in the SIP standard is expanded, make the information field after the expansion can the carried terminal equipment identification information.Thereby, can utilize existing mechanism to realize the transmission of Terminal Equipment Identifier information.
For the SIP node of not being familiar with expansion back information field, the information field after the expansion is not handled, promptly skipped this part unacquainted information field, according to the follow-up territory in the realization principle continuation treatment S IP message of existing Session Initiation Protocol, therefore, can not influence the implementation procedure of existing Session Initiation Protocol.
Being example with expansion existing C all-Info information field below utilizes in the sip message existing information territory to carry and the method for transmission terminal equipment identification information describes to of the present invention.
The Call-Info information field carries the additional information of caller in request message, carry called additional information in response message, and therefore, the Call-Info information field is well suited for transmitting both sides' Terminal Equipment Identifier information.
Example 6, to increase a new purpose in the Call-Info information field be Terminal Equipment Identifier information with what carry in the expression Call-Info information field, and Terminal Equipment Identifier type and the separately expression of Terminal Equipment Identifier symbol, and its message format is as follows:
Call-Info:<urn:imei:350112408932969>;purpose=di
Wherein: di increases purpose newly, and the Terminal Equipment Identifier type is: IMEI, concrete Terminal Equipment Identifier symbol is: 350112408932969.The Terminal Equipment Identifier symbol here can have oneself independently nomenclature principle, also can adopt existing name.
Example 7, utilize existing purpose to carry Terminal Equipment Identifier information, its message format is as follows:
Call-Info:<urn:imei:350112408932969>;purpose=info
Wherein: info is existing purpose, and the Terminal Equipment Identifier type is: IMEI, concrete Terminal Equipment Identifier symbol is: 350112408932969.The SIP network functional entity of handling this information needs to understand the nomenclature principle of Terminal Equipment Identifier information, is Terminal Equipment Identifier information or original accessory information thereby can parse what carry in the Call-Info information field.The Terminal Equipment Identifier symbol here can have oneself independently nomenclature principle, also can adopt existing name.
Example 8, to increase a new purpose in the Call-Info information field be Terminal Equipment Identifier information with what carry in the expression Call-Info information field, and Terminal Equipment Identifier information only comprises: the Terminal Equipment Identifier symbol, and its message format is as follows:
Call-Info:<urn:00-20-ed-aa-49-e8>;purpose=di
Wherein: di increases purpose newly, and the Terminal Equipment Identifier symbol is: 00-20-ed-aa-49-e8.The Terminal Equipment Identifier symbol here should have oneself independently nomenclature principle.
The message format that the Terminal Equipment Identifier symbol only is set in example 9, the Contact header field is:
Call-Info:<urn:sip:user@example.com:03>;purpose=di
