The present invention relates to utilize in the communication network portable terminal to carry out the method for information search.When explanation was of the present invention, words such as user side, portable terminal, terminal user can alternately be used, and represent the identical network equipment.Portable terminal can be the mobile device of any kind, for example mobile phone, personal digital assistant (PIDA) etc.
Please refer to shown in Figure 1, its demonstration be the network system architecture that the present invention depends on, comprising portable terminal 10, door 20, IMS network 30 and the Internet (Internet) 40.IMS network 30 comprises a plurality of functional entitys, and the home subscriber server relevant with the present invention (HSS) 31, search application server (Searching-AS) 32 only are shown among the figure.Home subscriber server 31 is the databases in the IMS network 30, wherein stores the data relevant with service with the user, comprises user's authentication information, user's business information, roaming information of user or the like.Have different application servers at dissimilar services in the IMS network 30, described search application server 32 has and the Internet 40 search engines (for example google, MSN, Yahoo, Baidu etc.) between the function that communicates, the performance (screen size, resolution etc.) that also has according to terminal is carried out adapting function to file size, file layout etc.Portable terminal 10 and door 20 by the Proxy Call Session Control Function (P-CSCF) of IMS network 30 realize with IMS network 30 between communicate by letter.
The present invention can provide the Search Results of the most suitable this user's current state at the searching request of different user.Concrete implementation is please in the lump with reference to figure 2.
Step S100, user use searching service by door 20 registrations, register its log-on message.This door 20 is application frameworks, it is with on various application systems, data resource and different network (comprising IMS and Internet etc.) resources integration to a platform, and offer unified entrance of user, to realize " dialogue " between user and the network.Be connected by the interface of agreement separately between door 20 and the different type network, for example and promptly be to connect between the IMS network 30 by Gm and P-CSCF (CallSession Control Function, CSCF).The user can login door 20 by portable terminal and register, and also can register by internet terminal (as computing machine etc.) login door 20.After the user signs in to door 20, can see some registration content fields by user interface (UI), the user fills in personal information and/or chooses the option that conforms to individual preference on field, and submits to IMS network 30, can finish registration.The log-on message that the user registered can be stored in the home subscriber server 31.Log-on message for example can be the telecommunications industry client, the most normal search sport category, IT class and music category information.
Step S200, user utilize IMS user's login mechanism of standard to be registered to the IMS network.Before registering, the user obtains an IP and connects carrying, and finds the entrance (P-CSCF) of IMS network.The process of registered ims is: the user sends the SIP register requirement to the P-CSCF that has found, P-CSCF is transmitted to I-CSCF (inquiry CSCF) with request, I-CSCF routes requests to S-CSCF (serving CSCF) again, S-CSCF asks for verify data to user attaching server (HSS), user side repeats said process in response, if response is correct, promptly finish registration.Above standard I MS login mechanism has been prior art, need not give unnecessary details.After finishing registration, the service that the user can use IMS network 30 to be provided.
Step S300, user submit searching request by 10 terminals to IMS network 30, and promptly the user sends to IMS network 30 with the initial ranging key word that writes.After search application server 32 in the IMS network 30 is received this request, by Sh interface calling party attribution server 31 based on the DIAMETER agreement, read user's registration information, and with these information in a certain way (" with " and/or " or " etc.) be incorporated in the initial ranging key word of user input, form a final search key, and will submit to internet search engine to final search key.When the user submitted searching request to IMS network 30, it can specify an internet search engine, then searches for the internet search engine that application server 32 sends to final search key user's appointment; If the user then searches for application server 32 and can select a search engine for the user automatically at specifies Internet search engine not when IMS network 30 is submitted initial search request to.The process of above-mentioned integration user's registration information can be exemplified below: the search key that the user submits to network is " computer ", and the log-on message that the user registers in step 100 is sport category, IT class, music class, then search for application server 32 and will integrate these information, form a new search key (computer and (physical culture or IT or music)).Certainly, that the integration mode is not limited to is above-mentioned " with " and " or ", can be defined in the search application server 32 according to actual conditions.Except that user's registration information, user's current location information also can be used as the foundation of integrating key word.For instance, after IMS network 30 detects user's current location (as: Shanghai), can be automatically with user's current location information notice search application server 32, search application server 32 also joins current location information in the key word, forms new search key (computer and (physical culture or IT or music) and Shanghai).Thus, be information equally about the computer market market, the information of Beijing computer market conditions will be no longer searched be come out, and only has the information of computer market, Shanghai market can be searched to come out.Be example with search key " IMS " again, because IMS can be understood as IP Multimedia Subsystem (IP Multimedia System), also can be interpreted as Information Management System (information management system), so, when comprising " network " in user's the log-on message, then searched application server 32 is preserved, and will be filtered about the information of information management system relevant for the information of IP Multimedia System; Otherwise, when comprising " information management " in user's the log-on message, then will preferentially be preserved, and searched application server 32 filtered out about the information of IP Multimedia System relevant for the information of information management system.Formed new search key is used as final search key and sends to internet search engine after search application server 32 is integrated.
After step S400, search application server 32 are received Search Results from search engine, the result is made a summary, pick out obvious irrelevant information, and according to terminal capability (comprising the processing power, display capabilities, storage capacity of terminal etc.) size of Search Results is carried out adaptively, deletion exceeds the information of terminal capability scope.The process of summary is as follows: search application server 32 travels through whole Search Results in order, when comprising illegal key word in finding a certain Search Results, then deletes the full content of this clauses and subclauses correspondence.Illegal key word is set in advance in the listed files of searching in the application server 32, for example comprises vocabulary such as " evilnesses ".Program can read listed files automatically, and illegal key word is carried out canonical coupling with Search Results, if accurately coupling or fuzzy matching find it is illegal key word, then deletes the full content of this clauses and subclauses correspondence.In a specific embodiment, can do following setting: for common illegal key word, just do not allow to match whole word only, be set at accurate coupling; Illegal key word for definitely not occurring then uses fuzzy matching.
Step S500, the search application server 32 will make a summary and adaptive after the result return to the terminal user.
Step S600, terminal user receive after the result, obtains further information according to whether meeting its expected click.
To sum up, the present invention utilizes unified certification, charging, the preservation user profile of IMS, and the characteristics of calling the related service server easily, provides a kind of to satisfy the search service that user individual requires by the customizing messages that obtains the user.The variation of the equalization that one of ordinary skill in the art is done according to the present invention is for example carried out function replacement or combination, discrete with each module of the present invention, within the claim that all should still belong to patent of the present invention contains.
