Embodiment
For make purpose of the present invention, technical scheme, and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
The process that the UE that introducing the embodiment of the invention earlier provides registers as shown in Figure 1, comprising:
The registration notification message of step 101, reception UE; This registration notification message comprises user's public user identity of UE ownership;
The user generally has a plurality of UE, when the user need go to receive network state by a UE, then needs earlier this UE at network registry; Network generally all can distribute a public user identity to the user, in actual applications, this public user identity can be URI, in network, URI just can be unique this user of sign, thereby when the UE with this user registers, attach this user's URI, identifying this UE with this is the user who belongs to this URI;
The type of step 102, judgement registration notification message; If the initial registration notification message enters step 103; If go registration notification message, enter step 106;
In the time need not registering through the UE that registers, just send the initial registration notification message, the trigger network side is registered it; And when needing to remove registration through the UE of registration, then send and go registration notification message, the trigger network side is removed the registration to this UE; In actual applications, UE through registration also wants regular transmission refresh registration notification message, the refresh registration notification message can't the trigger network side be done any practical operation, the effect of refresh registration notification message is that the registration of this UE of informing network side is still effective, accordingly, if do not receive the refresh registration message of a UE for a long time, then can do the releasing location registration process to this UE.
Whether step 103, the judgement user equipment information file corresponding with URI exist; If enter step 104; If not, enter step 105;
If the UE corresponding to the described URI of step 101 is registration for the first time, then can not exist with this URI corresponding equipment message file, thereby will to whether existing corresponding user equipment information file to judge before the information of adding UE;
In actual applications, if in the user equipment information file without any the information of UE, can be with this user equipment information file deletion, thus reduce system loading, and then improve system effectiveness.
Fig. 2 has described the structure of the user equipment information file that the embodiment of the invention provides, as shown in Figure 2, user equipment information file 201 comprises user's URI and UE information, wherein UE information also comprises the unique identification that is used for identifying the network address of binding with URI, and corresponding information be searched and be revised to service server can according to this unique identification; Network address information with the URI binding; With the state information of the network address of URI binding, its value can be to activate or stop, and when a plurality of UE send associated person information, can only send associated person information to state for the UE that activates according to the state information of the described network address, and this is an option.
Before introducing the method that associated person information is provided that the embodiment of the invention provides, introduce blend address book earlier:
Blend address book is the function that the network equipment provides, comprise user equipment information file and contact addresses book, its effect just is equivalent to the contacts list of user at network side, some static and dynamic information that comprise the customer contact people, wherein static information comprises contact method, contact person's display name, contact person's personal information, contact person's hobby of contact person etc., and multidate information comprises contact person's presentation information, contact person's preference setting, contact person's communication capacity etc.
Below begin to introduce the method that associated person information is provided that the embodiment of the invention provides, as shown in Figure 3, provide the method embodiment one of associated person information to comprise:
The subscription request message one that associated person information is subscribed in step 301, reception, subscription request message one comprises user's URI;
Subscription request message one can be UE from subscriber equipment, also can be from service server; When from UE, initiatively send by UE by the user; When from service server, service server is that the user according to the user serves configuration information and triggers, and the user sets in advance a trigger message, will trigger service server and send subscription request message one when satisfying the condition of trigger message; Wherein, aforesaid user serves configuration information and is kept at generally speaking in the service server, comprises some configuration informations, as configuration information relevant with blend address book etc.;
Subscription request message one comprises URI, and the contact person's of subscription information can send to the UE of this URI correspondence, and URI transmits in the message body of subscription request message one; Wherein, contact person's information can comprise one or more the combination in contact person's presentation information, contact person's the user preference information;
Corresponding with the refresh registration request, the subscribe request of refreshing is also arranged, refresh subscribe request and also can play notification server subscribe request effective function;
The subscription request message two that step 302, generation and subscription request message one are corresponding;
The recipient of subscription request message two identifies and adopts the URI described in the subscription request message one, thereby can find corresponding UE according to the described URI in recipient's sign after receiving subscribing notification;
Subscription request message two is corresponding with subscription request message one, if subscription request message one is a subscription request message, then subscription request message two also is a subscription request message; If subscription request message one is long-term subscription request message, corresponding subscription request message two also is long-term subscription request message;
Further, can also in subscription request message two, filter be set, because the user may only need to subscribe to a kind of message in a certain big class message, be provided with filter and can guarantee only to return this kind message this moment in subscription request message two, thereby can reduce network traffics;
According to the difference of the associated person information of subscribing to, the contact information server that subscription request message two is sent to is also different, and wherein, subscriber information server can be to present service server and the user is provided with preference server etc.; If what subscribe to is contact person's presentation information, then subscription request message two is sent to and presents service server; If what subscribe to is contact person's preference configuration information, then subscription request message two is sent to user preference server is set; Accordingly, if subscription is other associated person information, then subscription request message two is sent to corresponding contact information server;
After contact information server has been received subscription request message two, if the associated person information that subscription request message two is subscribed to changes, then described contact information server can send the notification message that associated person information changes, generally speaking, this notification message can attach associated person information and the URI information after the variation, and this notification message directly sends to the network entity that sends subscription request message two; After the notified message of this network entity, will search the user equipment information file corresponding, according to the associated person information of UE information after corresponding UE sends this variation that writes down in this user equipment information file with this URI;
From the above, in the present embodiment, user or service server only need send subscription request message 1 one time, during associated person information after network entity send to change, URI according to the user, associated person information after the UE that belongs to this URI through registration returns variation, thus make the user only need send the associated person information of a subscription request message after can collecting variation from a plurality of UE, thus can not bring bigger processing burden to the user; And, owing to have only a UE or service server to send subscription request message, thereby refresh subscribe request and also have only a UE or service server to need to send, also be limited so refresh the quantity of subscribe request, thus can be not too much take Internet resources.
As shown in Figure 4, provide the method embodiment two of associated person information to comprise in the embodiment of the invention:
The subscription request message one that associated person information is subscribed in step 401, reception, subscription request message one comprises user's URI;
The subscription request message two that step 402, generation and subscription request message one are corresponding;
Step 403, subscription request message two is sent to and associated person information corresponding contact information server;
Step 404, receive the message that changes from the associated person information of contact information server;
Step 405, judge whether the state of the UE that writes down in the user equipment information file is activation; If enter step 406; If not, process ends;
At UE after network side registration, be after having write down the information of UE in the user equipment information file, if do not receive the refresh registration request of this UE in a period of time, except the registration of direct releasing to this UE, can also be earlier change the state of this UE into unactivated state, have only when this UE unactivated state after a period of time network side do not receive that still the refresh registration request just removes registration to this UE; Thereby can avoid directly this UE being removed registration, the user need be re-registered, can not bring too much trouble to the user;
Step 406, the associated person information after state sends variation for the UE that activates;
From the above, this method embodiment two compares the state that has further comprised UE and whether activates the process of judging with method embodiment one, and only send associated person information after changing for the UE that activates to state, thereby can reduce the amount of information that needs transmission, not only can reduce the taking of finite element network resource, also reduce taking the system resource of this network entity; Simultaneously, because the associated person information that state is unactivated UE after can't receiving variation, thereby can not impact the user.
As shown in Figure 5, provide the method embodiment three of associated person information to comprise in the embodiment of the invention:
The subscription request message one that associated person information is subscribed in step 501, reception, subscription request message one comprises user's URI;
The subscription request message two that step 502, generation and subscription request message one are corresponding;
Whether the UE that writes down in step 505, the judgment device message file is set to receive the associated person information after the variation; If enter step 506; If not, process ends;
Though the user has registered a plurality of UE to network side, but the user may not need at the associated person information that all receives on each UE after changing, thereby associated person information after some UE does not receive variation can be set, thereby not only can satisfy user's needs, can also reduce taking the finite element network resource when sending associated person information; The default value of this setting is for receiving, and the user can make amendment to this setting; Concrete amending method can be taked diverse ways according to concrete implementation difference, for example, with the blend address book is example, when blend address book adopts the mode of extend markup language (XML:Extensible MarkupLanguage) document management server (XDMS:XML Document Management Server) to realize, can use the PUT method of XML configuration access agreement (XCAP:XML ConfigurationAccess Protocol) to make amendment.
From the above, this method embodiment three compares with method embodiment two and has further comprised and judge whether UE receives the step of the associated person information after the variation, and the associated person information after only the UE transmission of the associated person information after being set to receive variation changes, thereby can reduce the amount of information that needs transmission, not only can reduce the taking of finite element network resource, also reduce taking the system resource of this network entity; Simultaneously, because the user need not receive associated person information after changing at the UE that is set to not receive associated person information, thereby can not impact the user.
Suppose to have registered two UE under a user's the URI, be to have write down two UE in the user equipment information file, be respectively UE1 and UE2, method flow as shown in Figure 6, provide the method embodiment four of associated person information to comprise the steps in the embodiment of the invention, wherein associated person information is kept in the associated person information document:
The information of UE2 has record in the user equipment information file, in actual applications, according to concrete implementation difference, concrete triggering method is also different, for example, when adopting Session Initiation Protocol, can use the REFER reference method to trigger the variation that other equipment on the user equipment information file are subscribed to contact person's information document on the blend address book;
The subscription request message two that step 603, generation and subscription request message one are corresponding;
In actual applications, because network side can be preserved each contact person's information, for example aforesaid blend address book, certainly also may be the functional entity of other realization identity function, wherein, associated person information is kept in the associated person information document, thereby needs the updating contact information document, and aforesaid embodiment one, embodiment two and embodiment three also have this step of updating contact information document in actual applications;
Because be that UE1 initiatively subscribes to associated person information to network side, so adopt the associated person information of the corresponding mode of subscribing manner after the UE1 transmission changes that is adopted with UE1;
UE2 is the passive renewal to network side subscription associated person information document, and this subscribing manner may be different with the subscribing manner that UE1 is adopted, thereby the subscribing manner that adopted according to UE2 of network side, adopt the renewal of corresponding advice method notice UE2 associated person information document;
In actual applications, the quantity of UE2 may have a plurality of, because UE1 has initiatively subscribed to associated person information, and the associated person information after UE1 sends variation that network side can be independent, thereby when sending the notice of associated person information document renewal, need not send to UE1 to UE2;
In the present embodiment, UE can receive the trigger message of network side, the renewal of passive subscription associated person information document, thus make UE can carry out the preparation of the notice that receives contact person information updating, thereby can improve the treatment effeciency of UE, thereby can satisfy user's needs.
Fig. 7 is the signaling process figure that the method embodiment five of associated person information is provided in the embodiment of the invention, in this embodiment: the user has two UE to be respectively UE1 and UE2, and use user's same SIPURI to register to converged ip (IP:Internet Protocol) message (CPM:Converged IPMessaging) service enabler, the CPM service enabler receives that register requirement finishes after the registration process device information update with UE1 and UE2 in the list of devices of blend address book (CAB:Converged Address Book), after the user uses UE1 to subscribe to certain contact person's service ability or user preference by CAB, the information updating that CAB will be provided with server from presence server or user preference according to list of devices is in user's UE2, and detailed process is as follows:
Step 701, user use UE1 to register to the CPM service enabler;
Detailed process is: (1) user uses UE1 to pass through service call conversation control function (the S-CSCF:Serving Call Session Control Function) registration of SIP REGISTER request to IP Multimedia System (IMS:IP Multimedia Subsystem) network; (2) succeed in registration, S-CSCF returns the success response of 200ok to UE1; (3) S-CSCF initiates registration according to initial filter criteria (IFC) to the CPM service enabler; (4) succeed in registration, the CPM service enabler returns the success response of 200ok to S-CSCF; (5) S-CSCF sends a notification message to the CPM service enabler according to the registered events of CPM service enabler subscription; (6) the CPM service enabler returns the success response of 200ok after notified;
Further, be example with the XML implementation, the notification message body comprises following information in (5) step:
<contact?id＝″99a9020″state＝″active″event＝″registered″>
<uri>sip:1.8.27.2.161@8.27.2.56:5060</uri>
</contact>
Step 702, CPM service enabler are write the information of UE1 to CAB;
Detailed process is: the CPM service enabler according in the notification message body＜contact " state " property value of element and " event " property value judge that the user is first registration, the contact address of acquisition and user's public SIP URI binding (for example: sip:1.8.27.2.161@8.27.2.56:5060), and this information is added in the list of devices that is kept at user among the CAB by the PUT method of XCAP agreement; The PUT method of use XCAP agreement is created user's facility information file in CAB message instance can comprise＜deviceinfo〉element, specific as follows:
<deviceinfo?xmlns＝″urn:ietf:params:xml:ns:device-lists″
xmlns:xsi＝″http://www.w3.org/2001/XMLSchema-instance″>
<devicelist?aor＝″sip:user1@example.com″/>
<contact?id＝″99a9020″state＝″active″>
<uri>sip:1.8.27.2.161@8.27.2.56:5060</uri>
</contact>
</deviceinfo>
＜deviceinfo〉element is the root element of facility information file, what represent this file description is facility information,＜deviceinfo〉root element comprises one＜devicelist〉and one or more＜contact element, wherein＜and devicelist〉unit have an essential aor attribute, its value is user's public SIP URI, be used for representing which user this list of devices belongs to,＜contact〉element is used for representing the user institute current contact address of use equipment, he comprises two attributes, be respectively id attribute and state attribute, wherein the id attribute is used in this its value of contact address of unique sign and the registration event notification message body that the CPM service enabler is received＜contact〉the id property value of element is consistent, the state attribute is used for representing the login state of this contact address, its value can be: active, terminated, in addition,＜contact〉element also comprises one＜uri〉daughter element, its value is a SIP URI, i.e. the current contact address of user UE1; Preferably, can also comprise certain equipment of indication and whether receive the configuration information that associated person information changes;
Further, the CPM service enabler judges that according to the content in the message body of notification message the process how to handle is as follows:
If in the notification message of receiving＜and contact〉" state " property value of element is " active ", and the value of " event " attribute is " register " or " created ", then the user's this time is registered as initial registration, the CPM service enabler is by contact address information and the id attribute of interpolation in the user equipment information file of PUT method in CAB of XCAP agreement with user's public SIP URI binding, if in CAB, user's facility information file does not exist, and then creates to comprise and the contact address information of user's public SIP URI binding and the facility information file of id attribute;
If in the notification message of receiving＜and contact〉" state " property value of element is " active ", and the value of " event " attribute is " refreshed " or " shortened ", then the user be registered as refresh registration, do not need to change the content of user equipment information file among the CAB;
If in the notification message of receiving＜and contact〉" state " property value of element is " terminated ", then the user's this time is registered as register requirement, in the DELETE method deletion user equipment information file of CPM service enabler by the XCAP agreement＜contact element the id property value therewith in the notification message＜contact the id property value of element is identical＜contact element and daughter element thereof, or with this＜contact " state " property value of element changes " terminated " into;
Step 703, create successfully, CAB returns success response to the CPM service enabler, and this success response can be 201Created message;
Step 704, user use UE2 to register to the CPM service enabler;
The user uses the public SIP URI (sip:user1@example.com) identical with abovementioned steps 701 to register to CPM business service engine by UE2, concrete process such as step 701 description;
Step 705, CPM service enabler are write the information of UE2 to CAB;
The CPM service enabler is according to the information in the notice, obtain the contact address of UE2: sip:1.8.27.2.172@8.27.2.56:5060 (it is identical with the described method of step 2 with the method for the contact address of the UE2 of user's public SIP URI binding that the CPM service enabler obtains) from notification message, and this information is added in the list of devices that is kept at user among the CAB by the PUT method of XCAP agreement, further, can also comprise certain equipment of indication and whether receive the configuration information that associated person information changes;
Step 706, create successfully, CAB returns success response to the CPM service enabler;
Step 707, user initiate to subscribe to the request of contact person's presentation information and user preference information by UE1, and this is asked as subscription request message one;
The instantiation that a kind of use Session Initiation Protocol (SUBSCRIBE) method of subscribing to is described subscription request message one is as follows:
