Be elaborated below in conjunction with a complete operation flow.
A, user are provided with Service Trigger Information by client.
Client is for supporting the mobile phone of XCAP agreement, by the PUT method Service Trigger Information is saved in first server as XDMS.The particular content of PUT message body is exemplified below, and the capable and message header of information order can comprise:
PUT?http://URL?HTTP/1.1
Content-Type:application/trigger+xml
Host:trigger.example.com
The Service Trigger Information content is described with XML in the message body:
<trigger?id＝″001?″>
<condition>
<presence>
<entity?uri＝″sip:sunqian@example.com″>
<display-name>sun?qian</display-name>
</entity>
<changed?to＝″open″>
/pidf:presence/pidf:tuple/pidf:status/pidf:basic
</changed>
</presence>
</condition>
<action?id＝″01″>
<service>SMS</service>
<contact>tel?uri:13048907033</contact>
<content?xml:lang＝″en″>hello！</content>
</action>
</trigger>
Wherein＜and trigger〉content that comprises of element is Service Trigger Information, has a unique identification id.Service Trigger Information mainly comprises:
Trigger condition＜condition 〉, comprise status condition, as present condition＜presence and locality condition＜location etc.Present condition＜presence〉also comprise present body sign＜entity and present trigger condition＜changed etc.Trigger condition can also comprise time conditions, as the moment or time period condition.
Trigger action＜action 〉, comprise type of service＜service 〉, business tine＜content 〉, identification of contacts＜contact〉etc.
" short message.
Above Service Trigger Information uses XML to be described, and can certainly adopt other modes to describe and store, and as relation database table etc., its content and form also are not limited to above description.
B, first server are preserved Service Trigger Information, and second server obtains Service Trigger Information from first server.
Usually second server has been subscribed to the variation of XML document in first server, therefore when Service Trigger Information changes as establishment, modification or deletion, then can in time notify second server, second server to upgrade the Service Trigger Information of own buffer memory.Certain first server and second server also may be incorporated in together, and the Service Trigger Information that first server need not be synchronously up-to-date is to second server, but the Information Security of Service Trigger Information and sharing can be weaker.
C, second server obtain the presentation information relevant with trigger condition from presence server.
Second server presents the body sign and presents trigger condition according to presenting condition in the trigger condition, comprising, subscribes to the presentation information that presents body to presence server.Present body sign and be generally SIP URI, perhaps unified resource identifier such as presURI, one of unique identification presents the body resource.Present trigger condition and point out what value is which presentation information become, the variation of descriptive element value or property value.Often only relate to seldom presentation information element because present trigger condition, there is no need to subscribe to a variation that presents whole presentation information of body resource, in order to save network traffics, filtering information can be set in subscribe message, only obtain and present the related presentation information of trigger condition and change and get final product.The subscribe message that contains filtering information is exemplified below, wherein capable the and message header main contents of information order:
SUBSCRIBE?sip:sunqian@example.com?SIP/2.0
accept:application/simple-filter+xml
from:<sip:user@example.com>；tag＝47clc9c0
to:<sip:sunqian@example.com>
p-asserted-identity:<sip:user@example.com>
event:presence
SUBSCRIBE and NOTIFY method about Session Initiation Protocol specifically can be with reference to RFC3856.
Message body comprises the filtering information collection, describes with XML:
<？xml?version＝″1.0″encoding＝″UTF-8″？>
<filter-set?xmlns＝″urn:ietf:params:xml:ns:simple-filter″>
<ns-bindings>
<ns-binding?prefix＝″pidf′urn＝″urn:ietf:params:xml:ns:pidf″/>
</ns-bindings>
<filter?id＝″123″uri＝″sip:sunqian@example.com″>
<trigger>
<changed?from＝″closed″to＝″open″>
/pidf:presence/pidf:tuple/pidf:status/pidf:basic
</changed>
</trigger>
</filter>
</filter-set>
Wherein at filtering information＜filter〉in＜trigger element content and to present trigger condition be corresponding.In addition＜filter in when to be which presentation information taken place to send the notice when which changes except being provided with, can also be provided with in the notice of transmission and will comprise which presentation information, only send and present the required presentation information of trigger condition and get final product the size of minimizing notification data bag.Concrete can use＜waht〉the element description:
<filter?id＝″123″uri＝″sip:sunqian@example.com″>
<what><include?type＝″xpath″>
//pidf:tuple/pidf:status[pidf:basic＝″open″]/pidf:basic
</include></what>
</filter>
The presentation information element that needs or attribute are used the xpath language column at＜include〉get final product in the element.
General presence server need carry out authentication for the subscription of presentation information.If second server had carried out authentication to client before subscribing to presence server certainly, the presentation information that perhaps presents the body resource is full disclosure, also can be without authentication, as representing the presentation information that presents the body resource of broadcasting station or TV station for one is programme, then be full disclosure, need not authentication can provide.Second server can be earlier sends authentication request according to Service Trigger Information to general-purpose rights management server GPM, receives behind the result of authentication success just to presence server acquisition request presentation information.
Usually each presents body all corresponding authorization configuration, and which presentation information whom indication can provide to.Though be the subscription that second server is initiated to presence server among the present invention, actual subscriber is that the object of authentication should be the user that the client correspondence of Service Trigger Information is set at first.Service Trigger Information is kept at below the User Catalog of first server, the unified resource identifiers, URIs information that has also comprised the user herein, second server has pointed out that in the subscription request message that presence server is initiated actual is that URI by the Service Trigger Information owner pulls subscription, presence server carries out authentication according to the authorization configuration that presents body to this URI, determines whether to provide and provide which presentation information.Generally can use the p-asserted-identity field value in the SUBSCRIBE message to carry out authentication as Service Trigger Information owner's URI.
Presence server also can be managed GPM (Global PermissionManagement) server to general-purpose rights and send authentication request in addition, carry out authentication by the general-purpose rights management according to authorization configuration, return authenticating result to presence server then, presence server can only be handled the presentation information subscribing notification function of core like this, the function of authentication is separated, and the GPM server can be used as public authentication functions parts simultaneously for the multiple business service, as providing authentication for location server simultaneously.
If the authentication success, then presence server is to the presentation information of second server return authorization.When if second server receives the notice of failed authentication, can send the notice that the relevant presentation information of indicating services trigger message can't obtain to client.Simultaneously can be set to suspended state by this Service Trigger Information, can not detect its trigger condition again.After the user makes amendment to Service Trigger Information by client again, its state can be set to state of activation again.
The presentation information that D, basis are obtained is when trigger condition satisfies, and second server sends professional trigger notice to service server.
Except presenting status condition such as trigger condition, can also comprise time conditions simultaneously in the trigger condition, indication triggers the professional concrete moment or time period.As trigger condition＜condition in the above-mentioned steps A〉in can also comprise a time period condition＜period simultaneously:
<period>
<from>2006-07-01T17:00:00</from>
<until>2006-07-02T19:00:00</until>
</period>
Comprise a time started＜from〉and concluding time＜until, its time format can comprise year, month, day, hour, min, second and time-zone information, indication only could trigger professional in this time period.When comprising time conditions and status condition simultaneously in the trigger condition, then second server just obtains state information to state server when described time conditions satisfies.Can significantly reduce network traffics like this, because the detection of time conditions only need get final product in second server inside, the detection of status condition then needs second server just passable to the state information that state server constantly obtains variation.
If unqualified date information in this time conditions then can be represented this time period of every day; If represent then that this sky of every month should the time period unqualified days, and the like lack the time period expression way of other information.Certainly time conditions also can be represented constantly, when having only＜from〉or have only＜until during element or two elements just expression is constantly when identical; Perhaps use an other element＜timer〉expression moment condition, indicate a concrete time point.
After an acyclic time conditions corresponding service trigger message has been performed, then this Service Trigger Information can be deleted automatically by second server, perhaps be changed to state of termination, the Service Trigger Information second server that is in state of termination can not go to detect and handle.Second server can be handled with logic OR, logical AND between a plurality of in addition time conditions.
The presentation information of subscribing to presence server as second server in a default time period has satisfied and has presented trigger condition, and then second server sends professional trigger notice to service server.Can have a lot of service servers simultaneously in the communication system, second server determines which kind of agreement to send professional trigger notice to which service server or which address with according to type of service, and this can be pre-configured in the second server.
As type of service is short message, and then second server uses SMPP agreement transmission identification of contacts and business tine to short message service center; Type of service is a Multimedia Message, and then second server uses MM7 interface protocol transmission identification of contacts and business tine to the Multimedia Message center; As type of service is Email, and then second server uses smtp protocol transmission identification of contacts and business tine to e-mail server; As type of service is instant message, and then second server uses SIP MESSAGE agreement transmission identification of contacts and business tine to server of instant message.No matter adopt any agreement, all will point out to send the information of what content in essence, or the business of what content is provided to whom.The protocol type that as far as possible adopts service server to support at present when application is of the present invention, need not the new protocol interface of service server expansion like this.
In the present embodiment, second server can be ordered to the SUBMIT SM that short message service center sends in the SMPP agreement, identification of contacts＜contact in the Service Trigger Information is set in its destination_addr field 〉: 13048907033, the business tine＜content in the Service Trigger Information is set in the short_message field 〉: hello! Concrete SMPP agreement can be with reference to the corresponding standard standard, as GSM 03.40 standard such as short message such as grade.
In the Service Trigger Information, can trigger the business of a plurality of types of service.In present embodiment, can also comprise the trigger action that the another one type of service is Multimedia Message MMS simultaneously:
<action?id＝″02″>
<service>MMS</service>
<contact>tel?uri:13760463639</contact>
<content>http://content.example.com/mms.gif</content>
</action>
Its multimedia messaging service, MMS content can be video-mail, voice mail, image mail or text-mail etc. and combination thereof, its form is generally based on MIME (Multipurpose Internet Mail Extensions, RFC 2045-2049), second server sends to MMSC by the MM7 interface with business tine and identification of contacts, and concrete MM7 interface protocol can be referring to Multimedia Message and WAP (wireless application protocol) WAP (Wireless Application Protocol) relevant criterion standards such as 3GPP TS23.140.The direct multimedia information content of store M IME form in the business tine also can only be stored data or resource links such as simple text, picture, again these data or resource link is packaged into the MIME form when sending professional trigger notice with the MM7 interface.Adopt resource link can not be used in storage service content-data in first server, and content server is set separately, be used to store the actual business tine data such as the content of Multimedia Message, service server is when the user provides business, and service server or user terminal can obtain concrete resource data from content server.
In the present embodiment, except triggering a short message, second server also sends a professional trigger notice to MMSC by the MM7 interface simultaneously.When as seen type of service is more than one in Service Trigger Information, can make different types of service related different business tine and identification of contacts; When sending professional trigger notice, second server sends its related identification of contacts and business tine to each type of service corresponding service server respectively.
After second server sends professional trigger notice success, can send a notification message to the client that Service Trigger Information is set, indicating services is triggered, for the more clear timely triggering situation that must allow the user understand business, can be when at first Service Trigger Information being set, for each Service Trigger Information is provided with a professional title that triggers, in above-mentioned notification message, comprise this business and trigger title, be performed so which Service Trigger Information the user understands.Simple, second server can send a short message notification message that comprises professional triggering title to user's mobile phone through the SMSC of short message service center and get final product.If business tine sent to the user that Service Trigger Information is set originally certainly, just there is no need to have sent above-mentioned notification message.
Can in Service Trigger Information, increase notification action＜notify〉information, indication will send a notification message in which way to whom after professional trigger notice sends successfully.If notification action＜notify is not set〉information, then after sending successfully, professional trigger notice do not notify the user.Give tacit consent to such an extent that advice method can be short message.Notification action＜notify〉information content is exemplified below:
<notify?method＝″SMS″>
<address>13760463639</address>
<note>success！</note>
</hotify>
Optional in addition, can also be at＜notify〉content＜note of notification message is set 〉, if be provided with the content＜note of notification message 〉, then send successfully the mode that the back is provided with in the method attribute and send＜note in professional trigger notice in content.
E, service server provide professional according to described notice.
After service servers such as SMSC of short message service center or Multimedia Message center MMSC receive professional trigger notice, business tine is sent to the mobile phone of identification of contacts correspondence by short message or Multimedia Message.Service server can also be initiated service conversation except sending the message, and as instant message IM session, PTT PoC session, conference telephone etc., the participation number of session is no less than 2 usually.In next embodiment, will describe the situation that triggers service conversation in detail.
If a server only is set in the system as trigger device, then in the present embodiment among the step B first server and second server can omit alternately, the description of other steps replaces with trigger device with first server and second server and gets final product.
Specific embodiment two, present embodiment is realized following application scenarios: in the moment of setting, the user who satisfies status condition in the predetermined group is initiated cluster conversation, as instant message IM session, PoC session etc.The Service Trigger Information that is provided with is exemplified below:
<trigger?id＝″002″>
<condition>
<timer>2006-07-01T12:00:00+08:00</timer>
<group-filter?uri＝″sip:mygroup@example.com″>
<presence><sphere>home</sphere></presence>
</group-filter>
</condition>
<action?id＝″als″>
<service>PoC?session</service>
</action>
</trigger>
Service Trigger Information comprises a time conditions＜timer in the present embodiment〉2006-07-01T12:00:00+08:00＜/timer 〉, and to the system states filter condition＜group-filter of group member 〉, its uri attribute has been specified the group identification " mygroup@example.com " that will carry out member screening, presentation information＜presence〉＜sphere〉information is in for " home ".Present embodiment does not specify business tine and identification of contacts in trigger action, because it is to initiate a PoC session that type of service has in fact indicated business tine, and according to＜group-filter〉group member that obtains of part screening is identification of contacts.Be also can comprise the information of indicating identification of contacts in the trigger condition, type of service also can have been indicated business tine information.
When trigger device detects time conditions and satisfies, obtain member's tabulation of group " mygroup@example.com " earlier to the server of depositing group information, as obtaining to shared cluster server Shared GroupXDMS.Subscribe to the presentation information of obtaining member's tabulation to presence server then, need in can a subscription status condition＜sphere〉information, trigger device filters out presentation information＜sphere after receiving presentation information〉value be the member of home, send the indication of professional trigger notice to the PoC server and will initiate PoC session the member who filters out.If the number of members that certain trigger device detects screening is less than 2 people, then can not send professional trigger notice, but send the notice that the indication number of members is less than 2 people to the user that Service Trigger Information is set, as sending an Email that comprises content of announcement to this user by smtp protocol.Send in the professional trigger notice of PoC server and comprise that the member's who filters out URI also is identification of contacts and the indication information that will initiate PoC session to these people.The PoC server is notified to initiate the INVITE request to these members, sets up PoC session.
The SIP INVITE request of the professional trigger notice cluster conversation that also can be trigger device directly initiate to the PoC server as the PoC client, after PoC server and member set up session connection, trigger device disconnects and being connected of PoC server by SIP BYE instruction again, and the PoC session continuation.
Perhaps trigger device sends a SIP MESSAGE message as professional trigger notice to the PoC server, the URI that wherein comprises the member who filters out in SIP MESSAGE message body also is an identification of contacts, with the indication information that will initiate PoC session to these people, the main contents of SIP MESSAGE message are exemplified below:
MESSAGE?sip:PoCServer@domain.com?SIP/2.0
From:sip:trigger@domain.com；tag＝49513
To:sip:PoCServer@domain.com
Content-Type:application/trigger-notification+xml
<？xml?version＝″1.0″encoding＝″UTF-8″？>
<trigger-notification>
<resource-lists><list>
<entry?uri＝″sip:PoC-User?A@domain.com″/>
<entry?uri＝″sip:PoC-User?B@domain.com″/>
<entry?uri＝″sip:PoC-User?C@domain.com″/>
</list></resource-lists>
