Description

Search system and searching method
Technical field
The embodiment of the invention relates to moving communicating field, especially a kind of search system and searching method.
Background technology
At present, the network user's user profile comprises user's communications wish, communication capacity, communication equipment information and userspersonal information etc., and the user need search out qualified user according to some information (part that belongs to user profile) of other users.
Search agent (Search Proxy, SP) mainly be the function of finishing document searching, promptly need to finish in realization following function: receive extending mark language (eXtension Markup Language, XML) document management client (Document Management Client, XDMC) be subscriber equipment (User Equipment, searching request UE); Analysis request and forward the request to this territory the XML document management server (XML Document Management Client, XDMS), the XDMS that perhaps request is forwarded to other networks handles; Collect the response message of all XDMS, send to UE after filtering through combination.
Therefore SP has only the function of document searching, the ability that does not have search subscriber information, because the personal information in the user profile is managed at XDMS, user's facility information, ability information and wish information are then in presence server (Presence Server, PS) management.
Prior art one
As shown in Figure 1, be existing Open Mobile Alliance (Open Mobile Alliance, OMA) structural representation of XDMSV2.0 search agent system context.The Shared XDMSs of XDMS comprises 3 XDMS, comprising Shared Profile XDMS (maintenance customer's personal information), Shared Group XDMS (safeguarding public group), Shared List XDMS (safeguarding privately owned group and address book), but personal information mainly is the personal information that user oneself safeguards oneself at present, can revise and inquire about, and other users want to check the function that can only use search.And other information of user, a part that then presents (Presence) information as the user as ability information, wish information and facility information is kept at Presnece Server and safeguards.
Referring to shown in Figure 2, be the process flow diagram of existing terminal searching processing of request process based on OMA XDMS V2.0 search agent system, detailed method is as follows:
Step 101, (Aggregation Proxy AP) sends searching request search subscriber personal information and online information (Search with XDM﹠amp to XDMC to Aggregation Proxy; Online)
Search for qualified user, whether online these conditions comprise the part of personal information and information such as, because personal information is in XDMS, and whether online user's information in Presence Enabler, so this two category information is described separately;
Step 102, AP transmits the searching request that receives to SP;
Step 103, SP at first extracts search condition, searches for qualified userspersonal information to XDMS then;
Step 104, XDMS returns Search Results, SP is saved in this locality after receiving return results, and therefrom extract the user unified resource sign (Uniform Resource Identifier, URI);
Step 105, SP subscribes to these user's online information to PS;
Step 106, the PS return results;
Step 107, after all users' subscription was all finished, SP got up these two result combinations;
Step 108, the result after SP will make up returns to XDMC.
Therefore, though the prior art system architecture is fairly simple, the structure that meets existing OMA standard, all existing interfaces all need not change, but each terminal request all will be subscribed to through XDMS retrieval, PS, the process of result combinations, and efficient is very low, and the entire process process on backstage is very consuming time, bring very big delay to terminal, response speed is slow.
Prior art two
As shown in Figure 3, the synoptic diagram that presents the search agent system context of search XML document management server (Presence SearchXDMS) for expansion, this system has increased a Presence Search XDMS in existing OMA system, what be used for depositing the user presents (Presence) information.PresenceSearch XDMS is responsible for the presence information to Presence Server booking reader, and accepts the searching request of Search Proxy.Referring to shown in Figure 4, be process flow diagram based on the terminal searching processing of request process of Presence Search XDMS, detailed method is as follows:
Step 201, Presence Search XDMS starts, and obtains last all the state of user information of PS and is stored in this locality, by the subscribing relationship of PS, in time obtains the user state information of variation then, is updated to this locality;
Step 202, XDMC sends searching request search subscriber personal information and online information (Searchwith XDM ﹠amp to AP; Online);
Step 203, AP transmits the searching request that receives to Search Proxy;
Step 204, SP at first extracts search condition, searches for qualified userspersonal information to XDMS then;
Step 205, XDMS returns Search Results, and SP is saved in this locality after receiving return results, and therefrom extracts user's URI;
Step 206, SP obtains to Presence Search XDMS which user meets the search condition condition in the previous step Search Results;
Step 207, Presence Search XDMS return results;
Step 208, SP generates Search Results according to the result that Presence Search XDMS returns;
Step 209, the result that SP will search for returns to XDMC.
Therefore, though this existing method need not change the function of existing module in the current system, the delegated strategy of PS is still available, has increased new entity, and system complicates; The new communications burden of mutual increase of PS and Presence Search XDMS, the backstage is to result's integration processing still poor efficiency.
Prior art three
As shown in Figure 5, for realize the synoptic diagram of the contextual search agent system context of search subscriber presence by presence server (Presence Server), this system keeps original OMA system constant, but Presence Server has increased function of search, Search Proxy can directly send query requests to PS like this, finishes the retrieval of user's online status information by PS.Referring to shown in Figure 6, for realized the process flow diagram figure of search subscriber presence by Presence Server, detailed method is as follows:
Step 301, XDMC sends searching request search subscriber personal information and online information (Searchwith XDM ﹠amp to AP; Online);
Step 302, AP transmits the searching request that receives to Search Proxy;
Step 303, SP at first extracts search condition, searches for qualified userspersonal information to XDMS then;
Step 304, XDMS returns Search Results Search results, and SP is saved in this locality after receiving return results, and therefrom extracts user's URI;
Step 305, SP sends out thus and asks PS to retrieve these user's online status informations;
Step 306, PS returns Search Results;
Step 307, after two search complete, SP got up these two result combinations;
Step 308, the result after SP will make up returns to XDMC.
Therefore, though this method does not increase novel entities, existing system does not change, and uses existing protocol just can realize online user search function, the complicacy increase of Presence Server, and the backstage is to result's integration processing still poor efficiency.
In addition, also there are the following problems for above-mentioned prior art:
1, above-mentioned three prior aries all do not restrain the request of terminal, can not effectively reduce the communications burden of each inter-entity.Each request all can cause the interacting message between Search Proxy and XDMS, the PS, and this just makes that the communication between them is too frequent, causes the burden of background server too big;
2, prior art 2 and response time of 3 long, these two kinds of schemes only are fit to the smaller system of number of users.But in actual conditions, number of users may be very big, this makes that the result of search also can be very big, thereby causes having between Search Proxy and XDMS, the PS lot of data amount transmission (at this moment drawing the problem that the super large data volume transmits again), therefore can not guarantee rational response speed fully;
Though it is less 3, to transmit data volume in the prior art 2 and 3 between the server, but still there is the process that receives, resolves, merges XDMS and PS data in the Search Proxy processing procedure, this process is still brought extra time loss, is difficult to reach performance requirement.
Summary of the invention

In Data-Model, defined user's business information (comprising wish information and ability information), facility information and personal information, wherein personal information can be quoted the personal information that belongs to any NameSpace, this just in time includes personal information in, and maintenance provides convenience in the presence information, and personal information is included in and is carried out maintenance and management under " person " node in the presence information and can make amendment and inquire about equally, but also can carry out control of authority, and so user profile, comprise ability information, wish information, facility information and personal information all leave in user's the Presnece information, on the basis of the function that does not change existing Presence Server, increase the function of Search Proxy like this newly, realize simple, framework is simply clear, signaling is simple, do not need to carry out to make that search performance is greatly improved alternately with XDMS.
As shown in Figure 8, be the structural representation of embodiment of the invention search system, comprise Aggregation Proxy (Aggregation Proxy, AP) 2, be used for the authentication and the route of searching request; Aggregation Proxy (Aggregation Proxy) 3 is used for the searching request of Aggregation Proxy 2 routes is transmitted; Presence server (Presence Server, PS) 4, be used to store the presentation information that comprises personal information, and search in user's presentation information according to the searching request that receives and to return Search Results.
Again as shown in Figure 8, presence server 4 comprises database 40, is used to store user's the presentation information that comprises personal information; Present search agent (Presence Search Proxy) 41, be used for searching in the user's of described database 40 storages presentation information according to the searching request that receives; The presence server module is used to safeguard presentation information.
(XML Document Management Client XDMC) sends searching request by the XML document administrative client.
Therefore, the search system of the embodiment of the invention can not have any impact to the ability of existing presence server.Present search agent as a module independently in logic, but have the characteristic of public data again with PS, so be called Presence Search Proxy.
Embodiment of the invention searching method comprises that according to the entrained search condition of searching request that receives search for, the information that will meet search condition is returned in presentation information.
As shown in Figure 9, be the process flow diagram of embodiment of the invention searching method, detailed step is as follows:
Step 501, XDMC sends searching request to AP;
Step 502, AP carries out scope check, and check result is returned to XDMC, if this searching request is authorization message then execution in step 503, otherwise finishes;
Step 503 after XDMC receives authorization message, initiates request to AP again;
Step 504, AP is routed to this searching request and presents search agent (Presence SearchProxy);
Step 505, presenting the search condition that search agent carries according to searching request searches in its user's who has presence information, wherein relate to the control of authority of user to search, comprise the personal information that " allow-publication " user controls this user and whether be allowed to search in the User-Profile of OMA definition, then user's personal information of having controlled this user of search permission does not allow searched;
Step 506 presents search agent Search Results is returned to AP;
Step 507, AP returns to XDMC with Search Results.
Before searching for, need issue user presentation information, as shown in figure 10, for presenting the process flow diagram that the user agent issues user's presentation information in the embodiment of the invention searching method, detailed step is as follows:
Step 401 presents user agent (Presence User Agent, PUA) issue user's presence information;
PUA may be positioned at user's terminal device, also can be positioned at application server, also may be arranged in network;
Step 402, call/session control function agency (Proxy-Call/SessionControl Function in the IMS core net, P-CSCF) should issue the request send to call/session control function server (Serving-Call/Session Control Function, S-CSCF);
Step 403, S-CSCF check this user initial overanxious rule (Initial filter criteria, IFC), the decision triggering rule;
Step 404, the request of should issuing is delivered to PS to S-CSCF according to triggering rule;
Step 405, PS checks user's authority, passes through scope check; Otherwise finish
Step 406, the PS storage comprises the presence information of personal information, and returns the 200OK response;
Step 407, S-CSCF gives P-CSCF with this response message;
Step 408, P-CSCF gives PUA with this response message delivery;
PS can notify the new presence information that comprises personal information to search subscriber after the PS storage presented (Presence) information.
More than provided the personal information that how to obtain the user on the PS, it is to issue agency's (can be user's terminal device, also can be application server, can substitute the application that its information is issued at the family) by the user to be published to PS's.
For example:
1, presentation information from the user to presence server that issue is acted on behalf of in the issue that presents of user A, ability information, wish information, facility information and personal information comprising the user, certainly these information also can separately be issued, such as once only issuing ability information and wish information and facility information in the issue, and in other time even equipment issue user's personal information.That is to say that information releasing can be a segment of full detail.
2, after user B reaches the standard grade, initiate searching request, wish that search city, place is " Shenzhen ", and the user of current " online ", this request is routed to and presents search agent, this is acted on behalf of, and the city, place is " Shenzhen " in the presentation information that only needs inspection active user issue, and current " online " is just passable, and qualified user profile is returned to user B.
If adopt the framework of existing OMA, then needing to arrive first city, the current place of Profile XDMS removal search is the user in " Shenzhen ", after waiting to return qualified user, go to subscribe to these users' presentation information to presence server again, find out the user of current " online " again, and then the user that will meet two conditions returns to user B.Performance is obviously very poor like this, causes Search Results very slow, and no matter adopt any in existing several schemes, all causes Profile XDMS and presence server to stand huge data volume and Signalling exchange frequency.
Therefore the embodiment of the invention has the following advantages:
1, present search agent no longer simultaneously and Presence Server and XDMS mutual simultaneously, improved performance greatly;
2, according to prior art, the user preserves a personal information at XDMS, in presence information, also can preserve the userspersonal information, cause data to repeat the user experience complexity, the embodiment of the invention does not re-use XDMS and safeguards personal information, but the userspersonal information is placed on maintenance on the Presence Server, and be embedded under " person " node of data-model definition, make data no longer repeat, make things convenient for user management, user experience is more reasonable.
3, only search for the search need that a piece of data just can satisfy user personal information, ability information, wish information and the facility information of search subscriber (can), realize simple, performance boost;
4, based on the appearance of the Presence Search Proxy of Presence Server, reduced network complexity;
5, at the user to other users' the personal information and the Syndicating search demand of presence information, the search plan that the embodiment of the invention provides is under the prerequisite of not specification violation, framework is simple, performance improves greatly.
Therefore, the search system of the embodiment of the invention and searching method do not need mutual between search agent and presence server and the XML document management server, reduced the complex interfaces degree, improved search efficiency, made framework simple simultaneously, user data no longer repeats.
It should be noted last that, above embodiment is only unrestricted in order to the technical scheme of the explanation embodiment of the invention, although the embodiment of the invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical scheme of the embodiment of the invention, and not break away from the spirit and scope of embodiment of the invention technical scheme.
