Abstract

A subscribing method based on session launched protocol uses NOTIFY message to inform subscriber that RIC listing information is added in said message and all resource state allowing said subscriber to subscribe can be obtained directly through RIC when primary subscribing and resubscribing are changed, enabling to use RIC as an independent message body to appear on NOTIFY message or using it as partial part of message body existed already on NOTIFY message.

Description

The method for subscribing of dialogue-based initiation protocol
Technical field
The present invention relates to the communication technology, particularly the method for subscribing of dialogue-based initiation protocol.
Background technology
Session initiation Protocol (Session Initation Protocol is called for short " SIP ") is " a kind of standard that on the net transmit speech (VoIP) " of internet engineering task group (IETF) in March, 1999 issue.
SIP is a signaling protocol, is used for the voice and video session of initialization, management and termination packet network, specifically is exactly with generating, revise and terminate session between one or more participants.SIP is a part of IETF multi-medium data and hierarchy of control structure, therefore many other agreements of it and IETF all are related, RTP (RealTime Transfer Protocol for example, be called for short " RTP "), Session Description Protocol (Session Description Protocol is called for short " SDP ") etc.
SIP mainly provides with session and has set up five the aspect functions relevant with termination, and they are:
(1) user location: the decision of the terminal system that is used to communicate by letter;
(2) user availability: the decision of the wish that the called party participates in communicating by letter;
(3) user capability: the medium of use and the decision of media parameter;
(4) session is set up: " ring ", the foundation of calling and called party's session parameter;
(5) session management: comprise and shifting and the termination session, revise session parameter, and call business etc.
SIP has two types message, and they are: (1) request: the message that is dealt into server from client computer.(2) response: the message that is dealt into client computer from server.
Every sip message is made up of following three parts:
(1) initial row (Start Line): each sip message is begun by initial row.Initial row is passed on type of message (being Method type, is response code) and protocol version in response in request.Initial row can be request row (request) or a statusline (response).
(2) SIP head: be used for pass-along message attribute and revise the message meaning.Their identical with the HTTP header field on syntax and semantics (in fact some head are exactly to borrow from HTTP), and always keep form:<name 〉:<value 〉.
(3) message body: be used to describe by initial session (for example, in Multimedia session, comprising the Voice ﹠ Video type of coding, sample rate etc.).During message body can be presented at request and respond.The clear signaling information of transmission in SIP initial row and head and the session description information outside the SIP scope distinguished of SIP.Possible message body type just comprises the SDP Session Description Protocol that this paper will describe.
From 1999 so far, the SIP basic agreement has developed into present RFC3261 from initial RFC 2543, and protocol contents has obtained very big expansion, and the signaling framework of its description is also more perfect.People no longer are satisfied with use SIP and finish basic calling control, more are to pay close attention to how to utilize SIP to realize value-added service flexibly.
What deserves to be mentioned is, in Session Initiation Protocol, provided the method for a kind of SUBSCRIBE/NOTIFY (subscribing).Wherein, the SUBSCRIBE method is used for subscribing to, and the NOTIFY method is used to transmit the notice of any variation of an incident.So-called event notice is exactly, and user or resource are initiated to subscribe to other resources, and owing to the latter has the former interested incident, the former can receive about the state of this incident and the notice of any variation afterwards.Fig. 1 illustrates the signaling process of this process.As shown in Figure 1, at first, step 101: subscriber (Subscriber) sends a subscription (SUBSCRIBE) message to informant (Notifier), and interested resource status pulls subscription.Resource status is meant a series of state information of user or device end herein, as: the position that the user is current, the ongoing activity of user, terminal electric quality etc.
Then, in step 102: if informant (Notifier) need carry out policy control to subscriber's (Subscriber) subscribe request, then send " 202OK " response, otherwise send one " 200OK " response to subscriber (Subscriber) to subscriber (Subscriber).The concrete operations of policy control have many kinds, a kind of typical policy control is as follows: subscriber equipment A is as the state of subscriber to informant booking reader's equipment B, if the informant can't know the state that subscriber equipment B is supported according to the information of this locality, then to inquire about its supported state with subscriber equipment B or its home device.The process of this inquiry is exactly a kind of policy control.This process may be an across a network, may be slow.In order to make the subscriber can in time obtain feedback, need reply one " 202OK " response policy control forward direction subscriber.
After this, in step 103, informant (Notifier) sends a NOTIFY (notice) message to subscriber (Subscriber), carries the content information of the ordered resource status of subscriber (Subscriber) in the message body of NOTIFY;
Step 104: after subscriber (Subscriber) receives NOTIFY, send one " 200OK " response, represent successfully to have received NOTIFY to informant (Notifier).
As mentioned above, sip message is made up of initial row, SIP head and message body, and the form of the NOTIFY in the flow process shown in Figure 1 as shown in Figure 2.
According to the Extended Protocol of SIP, allow informant (Notifier) that the resource status that subscriber (Subscriber) is pulled subscription is carried out policy control, promptly whether the condition that is provided with according to the user limits resource status and allows subscribed.In this case, for different subscribers (Subscriber), Notifier allows it to subscribe to different resource statuss, this moment may occur that only some just can obtain permission in the resource status that Subscriber subscribes to, tell Subscriber for this what state, do not provide a solution in the agreement at present.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method for subscribing of dialogue-based initiation protocol, makes the subscriber can know the situation that ordered resource status is partly allowed.
For achieving the above object, the invention provides a kind of method for subscribing of dialogue-based initiation protocol, comprise following steps at least:
The A informant carries out policy control to the resource status that the subscriber pulled subscription, and sends first message that includes the first information to the subscriber,
After the described subscriber of B receives described first message, from the described first information, directly obtain or allow whole resource statuss of subscribing to by the limited step computing of the described first information being obtained described informant.
Wherein, described first message is " NOTIFY " message.
In this external described method, after described steps A and B, also comprise following steps:
The described subscriber of C responds " 200OK " message to described informant.
In this external described method, when subscribing to first, before described steps A, B and C, comprise following steps:
Described subscriber sends " SUBSCRIBE " message, the state of the allocated resource that pulls subscription to described informant;
Described informant responds " 202OK " message to described subscriber.
In this external described method, reformulate when readding, comprise following steps:
Described subscriber sends " SUBSCRIBE " message to described informant, and request reformulates the state of readding allocated resource;
Described informant responds " 200OK " or " 202OK " message to described subscriber;
If described informant judges the content that described subscriber pulls subscription change having taken place, has just held described steps A, B and C.
In this external described method, when described informant's policy control changes, and this variable effect during the resource status that described subscriber was allowed to subscribe to, carry out described steps A, B and C.
In this external described method, comprise one of following content or its combination in any in the described first information:
The resource status element of allow subscribing to, forbid resource status element and the unsupported resource status element subscribed to.
In this external described method, make the resource status element that allows in the described first information to subscribe to constitute first set, forbid that all the resource status element of subscribing to constitutes second set, whole unsupported resource status elements constitute the 3rd set;
If first set is that whole resource statuss that sky or the following stated informant allow to subscribe to are sky in the described first information, then expression stops subscription;
If have only the first set non-NULL in the described first information, then directly allow whole resource statuss of subscribing to as described informant with first set;
If have only first, second set non-NULL in the described first information, then not allow whole resource statuss of subscribing to as described informant in first set with the part of second intersection of sets;
If have only the first, the 3rd set non-NULL in the described first information, then not allow whole resource statuss of subscribing to as described informant in first set with the part of the 3rd intersection of sets;
If the equal non-NULL of first, second, third set in the described first information is not then to allow whole resource statuss of subscribing to the part of the second or the 3rd intersection of sets in first set as described informant.
In this external described method, the described first information is the independent message body in " NOTIFY " message or the part of existing message body.
By relatively finding, the main distinction of technical scheme of the present invention and prior art is, subscribing to first, reformulating and read or informant's policy control when changing, the informant notifies the subscriber by NOTIFY, increase RIL (resource information tabulation in this message, Resource Information List), can be directly or obtain whole resource statuss of allowing this subscriber to subscribe to indirectly by computing from RIL.RIL can be used as one independently message body appear in the NOTIFY or as the some of the existing message body of NOTIFY.
Difference on this technical scheme, brought comparatively significantly beneficial effect, even subscribing mechanism is more perfect, allow the subscriber know the resource state information that to subscribe to, the resource state information that can not subscribe to and the unsupported resource state information of informant, thereby make the subscriber can make the adjustment of the scope of subscription, the adjustment of own resource State Control strategy according to these resource state informations.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Core of the present invention is, the informant increases resource information tabulation (Resource Information List in notifying subscriber's NOTIFY, be called for short " RIL "), make the subscriber directly or by computing to obtain whole resource status elements that this subscriber can subscribe to indirectly.Thereby the scope that the subscriber can be subscribed to according to these resource status element information adjustment, and the control strategy of own resource state elements.Correlation between the resource status that resource status that resource status, the Notifer permission that the resource status that all resource statuss, Subscriber subscribe to, permission Subscriber subscribe to is subscribed and Notifer support as shown in Figure 3.
Wherein, RIL describes the informant to allow the subscriber to subscribe to or do not allow resource status element that the subscriber subscribes to and the manifestation mode of unsupported resource status element, can be used as one independently message body appear in the NOTIFY or as the some of the existing message body of NOTIFY, as shown in Figure 4.And RIL can adopt Extensible Markup Language (extensible Markup Language is called for short " XML ") to encode.
Owing in RIL, can comprise resource status element (the Allow SubscribeResource Element that allows subscription, be called for short " ASRE "), forbid resource status element (the Forbid SubscribeResource Element that subscribes to, be called for short " FSRE ") and the combination in any of unsupported resource status element (UnsupportResource Information List is called for short " USRIL ") three parts or one of them.Wherein, ASRE be the informant by after carrying out local policy, the resource status element that allows the subscriber to subscribe to can be the set of individual element or a plurality of elements, wherein can comprise FSRE; FSRE be the informant by after carrying out local policy, forbid the resource status element that the subscriber subscribes to, can be the set of individual element or a plurality of elements; USRIL is the unsupported resource status element of the subscribed person of an expression part, can be the set of individual element or a plurality of elements.So, can derive the resource status element (Final Allow Subscribe Resource Element is called for short " FASRE ") that final permission is subscribed to by ASRE and FSRE, thereby can know whole resource status elements that the subscriber can subscribe to.
Below in conjunction with accompanying drawing, first execution mode of the present invention is described the situation that present embodiment is applied to the user when subscribing to first.
As shown in Figure 5, in step 510, the subscriber sends " SUBSCRIBE " message, the interested resource status element of this subscriber that pulls subscription to the informant.Such as, R1, R2 and R3 that the interested resource status element of subscriber user A is user B, so, user A sends " SUBSCRIBE " message, resource status element R1, R2 and the R3 of the user B that pulls subscription to user B.
Then, in step 502, the informant responds " 202OK " message to this subscriber.Because the related data of the resource status element that the subscriber orders might be in this locality, therefore, the informant need respond " 202OK " message to this subscriber, and the expression informant carries out policy control in the subscribe request to the subscriber.At above-mentioned case, after user B receives " SUBSCRIBE " message that user A sent, respond " 202OK " message to user A, be illustrated in the subscribe request of user A is carried out policy control.
Through after the step 503, after just the informant carries out policy control to subscriber's subscribe request, enter step 504, the informant sends " NOTIFY " message that includes RIL information to the subscriber.The coded system of RIL information can be XML, and a part that can be used as independent message body or existing message body appears in " NOTIFY " message, as shown in Figure 4.In RIL information, can comprise the combination in any of ASRE, FSRE and USRIL or one of them.At above-mentioned case, if the whole resource status unit of user B have R1, R2, R3, R4, R5, the resource status unit that user B supports have R1, R2, R3, R4, wherein R1, R2 are single resource status elements, R3, R4 are the resource status element sets, such as R3 comprises R31, R32, three sub-resource status elements of R33, and R4 comprises two sub-resource status elements of R41, R42.User B is receiving subscribe request and implementation strategy control back (policy control of user B is subscribed to resource status element R2, R3, R4 for allowing user A) that user A sends, and the RIL information that user B comprises in the message body of first " NOTIFY " message that user A sends can be as follows:
<RIL>
<ASRE>
<R2/>
<R3/>
</ASRE>
<FSRE>
<R1/>
</FSRE>
<USRIL>
<R5/>
</USRIL>
</RIL>
The resource status element that expression allows user A to subscribe to is R2 and R3; Forbid that the resource status element that user A subscribes to is R1; The unsupported resource status element of user B is R5.
Then, enter step 505, after the subscriber receives " NOTIFY " message, from the RIL information of " this NOTIFY " message, directly obtain or by the limited step computing of this RIL information being obtained whole resource statuss that the informant allows this subscriber to subscribe to, FASRE just, and, confirm to receive the success of " NOTIFY " message to informant's response " 200OK ".If the ASRE in the RIL information constitutes first set, FSRE constitutes second set, and USRIL constitutes the 3rd set, and it is as follows then to obtain the method for information by RIL:
If whole resource statuss that first set is sky or the following stated informant allows this subscriber to subscribe to are sky, then the expression termination is subscribed to;
If have only the first set non-NULL, then the whole resource statuss that directly allow this subscriber to subscribe to as the informant with first set;
If have only first, second set non-NULL, then not allow whole resource statuss of this subscriber's subscription in first set as the informant with the part of second intersection of sets;
If have only the first, the 3rd set non-NULL, then not allow whole resource statuss of this subscriber's subscription in first set as the informant with the part of the 3rd intersection of sets;
If the equal non-NULL of first, second, third set in the described first information is not then to allow whole resource statuss of subscribing to the part of the second or the 3rd intersection of sets in first set as described informant.
At above-mentioned case, user A can be known FASRE from ASRE and FSRE the RIL information of this " NOTIFY " message after receiving " NOTIFY " message of user B transmission.As shown in Figure 8, when ASRE and FSRE were non-intersect, FASRE equaled ASRE; When ASRE and FSRE intersected, FASRE equaled ASRE and the non-intersect part of FSRE; When ASRE comprised FSRE, FASRE equaled ASRE and removes the FSRE part; When FSRE comprised ASRE, it is empty that FASRE equals.Therefore, user A can know that the resource status element that is allowed to subscribe to by user B is R2 and R3.
In this enforcement, the subscriber can know the resource state information that can subscribe to, the resource state information that can not subscribe to and the unsupported resource state information of informant, thereby make the subscriber can make the adjustment of the scope of subscription, the adjustment of own resource State Control strategy according to these resource state informations.
Below in conjunction with accompanying drawing, second execution mode of the present invention is described, when present embodiment was applied to the subscriber and is in subscription status, strategy change took place in the informant, and this variable effect the situation of the resource status that the subscriber was allowed to subscribe to.
As shown in Figure 6, when change has taken place for informant's policy control, and when this change has influenced the resource status that the subscriber was allowed to subscribe to, just enter step 601, the informant sends " NOTIFY " message to affected subscriber, in this message body, carry the RIL information after policy control changes,, then stop subscribing to if informant's policy control changes all resources that will cause forbidding subscriber's subscribing notification person.Such as, user A is in subscription status, and that user A subscribes to is resource status element R2 and the R3 of user B, and this moment, change took place the policy control of user B, only allows R31 and R32 among user A subscription R2 and the R3, therefore, the strategy change of user B has influenced the resource status that user A is allowed to subscribe to, so user B need re-execute policy control, produce new RIL information, and send to user A by the message body of " NOTIFY " message.Wherein, new RIL information can be as follows:
<RIL>
<ASRE>
<R2/>
<R3/>
</ASRE>
<FSRE>
<R1/>
<R3\R33/>
</FSRE>
<USRIL>
<R5/>
</USRIL>
</RIL>
After the policy control change of expression user B, the resource status element that allows user A to subscribe to is R2 and R3; The resource status element of forbidding user A subscription is the R33 among R1 and the R3; The unsupported resource status element of user B is R5.
Then, enter step 602, after the subscriber receives " NOTIFY " message, from the RIL information of " this NOTIFY " message, directly obtain or by the limited step computing of this RIL information being obtained whole resource statuss that the informant allows this subscriber to subscribe to, FASRE just, and, confirm to receive the success of " NOTIFY " message to informant's response " 200OK ".This step is identical with step 505, does not repeat them here.
In the present embodiment, even change has taken place in informant's policy control, as long as this change has had influence on the user who is in subscription status, this user also can be known the resource state information that can subscribe to, the resource state information that can not subscribe to and the unsupported resource state information of informant by " NOTIFY " message that the informant sends, thereby make the subscriber can make the adjustment of the scope of subscription, the adjustment of own resource State Control strategy according to these resource state informations.
Below in conjunction with accompanying drawing the 3rd execution mode of the present invention is described, the subscriber that present embodiment is applied to be in subscription status initiates to reformulate the situation of readding to the informant.
As shown in Figure 7, in step 701, the subscriber sends " SUBSCRIBE " message to the informant, and request reformulates the state of readding allocated resource.Owing to subscribe to free restriction, if the subscriber wants to continue this subscription, just need in this time bar, initiate to reformulate to read, therefore, the content that the subscriber pulled subscription during this reformulated and reads does not change.If read owing to the interested resource status element of subscriber has taken place to change reformulating of initiating, change has taken place in the content that the subscriber pulled subscription during then this reformulated and reads.Such as that user A subscribes to originally is resource status element R2 and the R3 of user B, if user A is owing to reformulating of initiating of time restriction read, then the content that pulls subscription in " SUBSCRIBE " message that user B sends of user A does not change; If user A is owing to reformulating of initiating of the resource status element R1 that wishes booking reader B and R3 read, then change has taken place in the content that pulls subscription in " SUBSCRIBE " message that user B sends of user A.
Then, enter step 702, the informant responds " 200OK " or " 202OK " message.If in step 701, the content that the subscriber pulls subscription does not change, and then responds " 200OK " message and process ends; If in step 701, change has taken place in the content that the subscriber pulls subscription, and then responds " 202OK " message, and the expression informant need carry out policy control again to the resource that the subscriber subscribes to, and execution in step 703 to 705.
In step 703, the informant carries out policy control to subscriber's subscribe request.
Then, enter step 704, the informant sends " NOTIFY " message that includes RIL information to the subscriber.This step is identical with step 504, does not repeat them here.
Then, enter step 705, after the subscriber receives " NOTIFY " message, from the RIL information of " this NOTIFY " message, directly obtain or by the limited step computing of this RIL information being obtained whole resource statuss that the informant allows this subscriber to subscribe to, FASRE just, and, confirm to receive the success of " NOTIFY " message to informant's response " 200OK ".This step is identical with step 505, does not repeat them here.
In the present embodiment, even the subscriber initiates to reformulate to read, also can know the resource state information that to subscribe to, the resource state information that can not subscribe to and the unsupported resource state information of informant by " NOTIFY " message that the informant sends, thereby make the subscriber can make the adjustment of the scope of subscription, the adjustment of own resource State Control strategy according to these resource state informations.
Though pass through with reference to some of the preferred embodiment of the invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
