Abstract
A method used for setting up an implicit subscription through SIP registering request comprises the following steps: 1) one user sends SIP registering request message having implicit subscription event information to a registration server; 2) after receiving the SIP registering request message from the user, the registration server performs user registration and sets up a subscription dialog with the user, according to the implicit subscription information; 3) the registration server ruturns the registration replying message back to the user; 4) then the user sets up an implicit subscription, according to the registration replying message. By expanding SIP registering request and the registration replying message in accordance with the present invention, the registration server is enabled to bind the registering request to the subscription request dialog, combine and deal with them. Through a dialog treatment simplifying process, the invention not only reduces flux of server web registration, but also reduces complexity of terminal users, and then improves effective treatment capability of communication equipments.
Description
Technical field
Patent of the present invention relates to the communications field, relates in particular to a kind of method of setting up agreement (SIP) register requirement establishment hidden subscription by session.
Background technology
Agreement (SIP is set up in session, Session Initiation Protocol), it is a kind of agreement that is used to set up Multimedia session of IETF RFC3261 definition, as the Internet era basic signaling, SIP has been widely used in packet networks such as Internet network, IMS network now, support various new business, for example the IMS network be 3GPP R5 and R6 based on the SIP framework, adopt the business network of multiple access technologies such as 3G/2G GPRS, WLAN.
SIP is a kind of agreement very flexibly, it uses little of telephone terminal, big to exchanging network system, in order to obtain terminal use's positional information, SIP is the location-based service establishment binding relationship of special domain by registration service generally, and the recording address in the contact address of Contact header field (promptly initiating the user of register requirement) and the To header field (communicating terminal of promptly being invited) is bound in registration service.A recording address can be bound one or more contact address, when the acting server in this territory (proxy) receives a SIP request, according to Request-URI (the Universal Resource Identity in this SIP request, universal resource identifier) and the record of recording address coupling, the contact address that can find the user to register.The SIP registration service comprises by register requirement and is used for increasing, deletes, refreshes, inquires about binding information, register requirement can increase the binding between a recording address and one or more contact address, the current bind address that the content that client can be deleted the front binding equally also can the query note address.
User's terminal is to support the terminal of SIP, can be mobile phone, also can be landline telephone.After the user terminal registration, often need to subscribe to dependent event, comprise register requirement, current state etc.Though the registrar in the existing solution can the process user initial registration, has following shortcoming:
1. increased the complexity of terminal.Existing endpoint registration is a tight binding with the instruction of subscription dependent event, and promptly the user need to initiate immediately to subscribe to, and registration and subscription often all is to handle by registrar after succeeding in registration.Network is by notification message, can logging off users; Behind the user log off, subscribe to also cancellation simultaneously.Registration and subscription are divided into two self-contained process and cause the terminal processes complexity.
2. increased the flow of network.Subscribing mechanism is kept the validity of subscribing to dialogue by periodically redefining, and a large amount of users keeps simultaneously and subscribes to dialogue, the requirement that will bring network traffics for network.
3. increased the expense of the network equipment.Communication apparatus such as registrar are handled registration and subscription simultaneously in user's registration lifetime, and safeguard registration and subscribe to dialogue, the effective processing capacity of reduction communication apparatus.
Summary of the invention
The expansion that the object of the present invention is to provide a kind of SIP of passing through is when registrar process user initial registration, and the method for subscribing to dialogue is created, refreshes and deleted to implicit expression.
Wherein, a kind of method by SIP register requirement establishment hidden subscription may further comprise the steps:
1) user sends the SIP login request message that carries the hidden subscription event information to registrar, initiates registration;
2) registrar is received user's SIP login request message, carries out user's registration, and according to the hidden subscription event information, creates the subscription dialogue with the user;
3) registrar returns registration reply message to the user;
4) user sets up hidden subscription according to registration reply message.
In step 2) in further comprise: registrar with the user create subscribe to dialogue before, registrar is set registration reply information.Described registrar reads the recording address of login request message and registration reply message, and the tag that adopts tag in Call-ID header field in the recording address of login request message, the From header field and set To header field in the registration reply information creates to subscribe to the user and talks with.
In step 4), further comprise: in judging described registration reply message, carry hidden subscription information, then set up corresponding hidden subscription dialogue according to the tag in the To header field in tag and the registration reply message in the Call-ID header field in the login request message, the From header field.
Before step 1), further comprise: sip message is expanded, to carry the hidden subscription event information; Described sip message comprises SIP login request message and registration reply message, and described expansion is included in newly-increased header field, newly-increased parameter or newly-increased label in the described sip message.
Comprise further that after step 3) implicit expression refreshes or refresh the step of subscription, wherein, registrar refreshed the timer of the described subscription dialogue of corresponding initial registration establishment simultaneously when implicit expression refreshed after the success of the heavy register requirement refresh registration of user timer.During the implicit expression deletion, registrar is deleted described subscription dialogue simultaneously after the user log off success.
According to the solicited message that carries hidden subscription in the SIP login request message, then a subscribe request has been received in the registrar supposition simultaneously.Step 2) in, judges in the registration reply information when registrar to have comprised the P-Associated-URI header field, then the default records address that the recording address of To header field adopts this header field in the subscribe request received of registrar.Judge in the registration reply information when registrar not comprise P-Associated-URI header field that the recording address of To header field adopts the recording address in the To header field in the described login request message in the subscribe request that registrar is received with default records address; The recording address of From header field adopts the recording address in the From header field in the described login request message.
In addition, in step 2) in, the duration of the Expire header field of the subscribe request that registrar is received is identical with Expire header field or Expire parameter duration in the described login request message, perhaps is the duration according to Expire header field in the described register requirement or the conversion of Expire parameter duration.The Contact header field of the subscribe request that registrar is received adopts the Contact header field in the described login request message.The Tag of the To header field of described subscription dialogue adopts the Tag of the To header field in the described registration reply message, perhaps is the unique identification according to the Tag conversion of the To header field in the described registration reply message.
Registrar with the user create subscribe to dialogue after, the user is to registrar booking reader incident bag, this customer incident bag comprises registered events, presents tabulation, Messages-Waiting, dialogue incident and watcher information.
Compared with prior art, create in the method for hidden subscription by the SIP register requirement in the present invention, by newly-increased SIP header field, the method of newly-increased parameter or label, expansion SIP register requirement and registration reply message, when the user when registrar is initiated registration, in login request message, just carried the incident of hidden subscription, make registrar that register requirement and subscribe request dialogue binding are merged processing, by simplifying the flow process of dialog process, both reduced the flow of registrar network, reduce terminal use's complexity again, improved the effective processing capacity of communication apparatus.
For making the present invention easier to understand, further set forth the present invention creates the method for hidden subscription by the SIP register requirement specific embodiment below in conjunction with accompanying drawing.

Embodiment
Further specify the specific embodiment of the present invention below in conjunction with Figure of description.
The present invention is by SIP expansion (comprising the expansion to SIP registration message and registration reply message), is implemented in the initial registration request and creates, refreshes and delete hidden subscription.So-called SIP expansion is meant that the increase partial content in the sip message realizes new function, and standard SIP allows to increase such expansion arbitrarily, but the definition of expansion is not added restriction, and the present invention is by newly-increased header field in the SIP extension field, newly-increased parameter, label etc.
With reference to shown in Figure 1, SIP network configuration of the present invention comprises registrar B and the user A, the C that are attached thereto by packet network such as Internet network or IMS (IP Multimedia System) network, adopt Session Initiation Protocol to set up session between registrar B and user A, the C, described user is for supporting the terminal of Session Initiation Protocol, as landline telephone, mobile phone etc.
In one embodiment of the invention, in registration transactions, all newly-increased optional header field (for example " Subscription ") carries out the SIP expansion in existing SIP register requirement and registration reply message, and this header field " Subscription " is as the sign of supporting the hidden subscription dialogue.If in SIP register requirement and registration reply message, include this optional header field (" Subscription "), represent that then the requesting party (user) of registration message and registration recipient (registrar) all support the hidden subscription dialogue function; " the Subscription header field, the recipient who then shows registration message does not support or can not set up hidden subscription if in registration reply message, do not comprise.The requesting party of registration message and recipient create, refresh and delete the hidden subscription dialogue according to the event type in this optional header field (" Subscription ").
Expansion is exemplified below to SIP:
The object of expansion is the SIP header field;
Newly-increased SIP header field is " subscribing to (Subscription) ";
The BNF grammer of the signaling that registration is subscribed to is as follows, and the definition of BNF grammer is based on the agreement of standard, no longer is described in detail here:
Subscription=" Subscription " HCOLON event-type* (SEMI extent) SIP header field place to use proxy ACK BYE CAN INV OPT REG MSGSubscription R, 2xx-----o-SIP header field place to use SUB NOT REF INF UPD PRA PUBSubscription R, 2xx-------
Employing is expanded Session Initiation Protocol, sets up flow process that the registered events of implicit expression between terminal use and the registrar subscribes to as shown in Figures 2 and 3.
Step 1: user A initiates initial registration to registrar B, sends SIP register requirement (Register) message, carries the event type of hidden subscription in login request message, and the SIP login request message is exemplified below:
REGISTER?sip:example.com?SIP/2.0
Via:SIP/2.0/UDP?pc34.example.com;branch=z9hG4bKnaaff
From:sip:joe@example.com;tag=99a8s
To:sip:joe@example.com
Call-ID:88askjda9@pc34.example.com
CSeq:9987?REGISTER
Max-Forwards:70
Subscription:reg
Expires:3600
Contact:sip:joe@pc34.example.com
Wherein, " Subscription:reg " is illustrated in this login request message and comprised the hidden subscription request.Also include recorded contents such as the Request-URI header field (in the present embodiment for REGISTER sip header field) of register requirement and the From header field in the recording address, To header field, Call-ID header field, Contact header field in register requirement.
Step 2: after registrar B receives register requirement, register according to the contact address and the recording address of register requirement.After succeeding in registration, set registration reply message, judge the incident that whether carries hidden subscription in this SIP login request message then.
Because in above-mentioned SIP login request message, carry request (" the Subscription:reg ") information of hidden subscription, at this moment, the registrar supposition is equivalent to receive simultaneously a subscription (SUBSCRIBE) request, and this SUBSCRIBE request message thes contents are as follows:
A). the recording address in the To header field in the subscribed recording address of its request universal resource identifier (Request-URI) appointment and this SIP login request message is identical, if but the recording address in this SIP login request message To header field by locking, then recording address adopts the default records address in the P-Associated-URI header field in the registration reply message;
B). its From header field is identical with From header field in this SIP login request message, if but the recording address in the SIP login request message From header field by locking, then the recording address in the From header field adopts the default records address in the P-Associated-URI header field in the registration reply message;
C). its To header field is identical with To header field in this SIP login request message, if but the recording address in the SIP login request message To header field by locking, then the recording address in the To header field adopts the default records address in the P-Associated-URI header field in the registration reply message;
D). its Call-ID header field is identical with Call-ID header field in this SIP login request message;
E). the Expire duration of its subscription is identical with Expire duration in this SIP login request message;
F). the event type of its Event header field for carrying in this SIP login request message, as " reg ", " presence " etc.;
G). its Contact header field is identical with Contact header field in this SIP login request message.
Then, registrar is according to the Call-ID header field in this SUBSCRIBE request, tag in the To header field in the From header field in tag and the registration reply message sets up and subscribes to dialogue, and, in the lifetime of this registration, the tag in the To header field in the registrar maintenance registration reply message is constant.
If the recording address in the login request message is not by locking, then subscribe request adopts the recording address in the login request message, in registration reply message, carried the indication information (as increasing optional header field " Subscription:reg ") of hidden subscription, registration reply message is exemplified below:
SIP/2.0?200?OK
Via:SIP/2.0/UDP?pc34.example.com;branch=z9hG4bKnaaff
From:sip:joe@example.com;tag=99a8s
To:sip:joe@example.com;tag=xyzygg
Call-ID:88askjda9@pc34.example.com
CSeq:9987?REGISTER
Subscription:reg
Contact:sip:server19.example.com
If in the login request message recording address joe@example.com by locking, then registrar is set up and is subscribed to dialogue according to the supposition of the default records address sip:joe1@example.com among the P-Associated-URI in registration reply message subscribe request.In registration reply message, carried the indication information (as increasing optional header field " Subscription:reg ") of hidden subscription, registration reply message is exemplified below:
SIP/2.0?200?OK
Via:SIP/2.0/UDP?pc34.example.com;branch=z9hG4bKnaaff
From:sip:joe@example.com;tag=99a8s

CSeq:9987?REGISTER
Subscription:reg
Contact:sip:server19.example.com
P-Associated-URI:<sip:joe1@example.com>,<sip:joe2@example.com>
In the present invention, because subscribe request is not that the user is to the actual initiation of registrar, therefore, after succeeding in registration, the register requirement that registrar is received is not simple register requirement, but receive the register requirement sent by the user and the indication of subscribe request, by the indication (Subscription:reg) that is implied in the subscribe request in the register requirement, make registrar read the recording address in login request message and/or the registration reply message, adopt the content in login request message and/or the registration reply message, construction plays complete subscription request message, subscribe to dialogue thereby make to set up between registrar and the user, registrar B returns registration reply message to user A then.
Step 3: user A receives the registration reply message from registrar B, if wherein carry hidden subscription information, then according to the Call-ID header field in the SIP login request message, the tag in the To header field in the From header field in tag and the registration reply message sets up corresponding hidden subscription dialogue.If wherein do not comprise the information of any hidden subscription, show that then registrar B does not support hidden subscription, perhaps set up failure.
Registrar with the user create subscribe to dialogue after, the user is to registrar booking reader incident bag, this customer incident bag comprises registered events, presents tabulation, Messages-Waiting, dialogue incident and watcher information.
Step 4: after registrar B sets up the registered events subscription dialogue of implicit expression, according to the method that RFC3680 describes, use this subscription dialogue, send the registered events NOTIFY to user A, notify user's subscription registration incident, the NOTIFY example is as follows:
NOTIFY?sip:joe@example.com?SIP/2.0
Via:SIP/2.0/UDP?server19.example.com;branch=z9hG4bKnasaii
From:sip:joe@example.com;tag=xyzygg
To:sip:joe@example.com;tag=99a8s
Call-ID:9987@app.example.com
