Description:
TECHNICAL FIELD 
     The disclosure relates to an inquiry technology and more particularly to an inquiry method, an inquiry system, an inquiry search server and an inquiry terminal. 
     BACKGROUND 
     With people communicating with each other more and more frequently, how to acquire desirable information more conveniently remains, as ever, an important research subject in information technology. The search technologies provided by companies like Google and Baidu realize the share of computer data resources and therefore remarkably expand the sources for the acquisition of information. Nonetheless, there are still a great amount of information and wisdom resources which are ‘hidden’ in people&#39;s brain but not input in a computer database. People generally get such information and wisdom by inquiring of people nearby about the information and wisdom, resulting in a low efficiency. 
     Meanwhile, voice communication technologies, although developed very early, are mainly applied to end-to-end real-time communication or real-time communication between limited groups known to each other, which is inconvenient for people to acquire information and wisdom resources from a wider social range. 
     Thus, it is needed a new inquiry communication technology by means of which an inquiry can be searched conveniently to acquire the information and wisdom resources ‘hidden’ in people&#39;s brain. Unfortunately, no related researches have been done in this field. 
     SUMMARY 
     The disclosure provides an inquiry method, an inquiry system, an inquiry search server and an inquiry terminal for users to inquire of each other about a question and acquire a corresponding answer.

     DETAILED DESCRIPTION 
     Embodiments of the disclosure are described below in detail with reference to accompanying drawings. 
       FIG. 1  is a schematic diagram illustrating the structure of an inquiry system according to an embodiment of the disclosure, and as shown in  FIG. 1 , the inquiry system provided in the disclosure includes an inquiry search server and an inquiry terminal and a target inquiry terminal connected with the inquiry search server. The inquiry terminal is a terminal initiating an inquiry request, and the target inquiry terminal is the inquiry terminal selected to answer the inquiry request initiated by the inquiry terminal. In the inquiry system provided herein, each inquiry terminal can initiate an inquiry request or answer an inquiry request initiated by another inquiry terminal as a target inquiry terminal. 
     The inquiry search server takes charge of maintaining and collating relevant information of all inquiry terminals. Relevant information of the user of the inquiry terminal is all stored in the inquiry search server, wherein the relevant information of the inquiry terminal includes at least one of: 
     the personal information of the user of the inquiry terminal and the information updated by the inquiry terminal in real time, wherein the personal information of the user of the inquiry terminal includes at least one of: 
     the name, the gender, the age, the ID card number, the home address, the skilled field, the demand, and the wish of each family member of the user of the inquiry terminal, and 
     the information updated by the inquiry terminal in real time includes at least one of: 
     geographical location information, the number of the target inquiry terminals required by the inquiry terminal to be included in a target inquiry terminal group, the number of the answers desired by the inquiry terminal, the idle/busy state of the receiving cache of the inquiry terminal and the points gotten by the inquiry terminal as a target inquiry terminal. 
     With the exception of the information updated by the inquiry terminal in real time, the other information, such as the personal information of the user of the inquiry terminal including the name, the gender, the age, the address and the skilled field of the user of the inquiry terminal, is usually relatively stable; the user of the inquiry terminal can register or modify the other information on the inquiry search server online or register the other information on the site or by making a long-distance call, in the latter case, the other information is input in the inquiry search server by the operating company for registration or modification, and the authenticity and the security of the other information are guaranteed by the operating company. Meanwhile, the inquiry search server assigns an inquiry terminal ID to each inquiry terminal, wherein the ID is the address of an inquiry terminal interacting with the inquiry search server. 
     The inquiry search server also takes charge of maintaining information of low stability of the user of the inquiry terminal, for example, recent problems, demands and wishes of the user of the inquiry terminal and the family members of the user of the inquiry terminal, such information is edited or modified by the user of the inquiry terminal on the inquiry search server online or registered by the user of the inquiry terminal on the site or by making a long-distance call and input in the inquiry search server by the operating company for edition or modification or directly edited or modified by the user of the inquiry terminal on an interface provided by the inquiry terminal. 
     The inquiry search server also takes charge of receiving and maintaining some instant information, including the keyword of the inquiry request currently initiated by the inquiry terminal, the current geographical location of the inquiry terminal and the empty/occupied state of the inquiry receiving cache of the inquiry terminal; these pieces of information are edited by the source inquiry terminal on an interface provided by the inquiry terminal and sent to the inquiry search server, or automatically acquired by the inquiry terminal and automatically updated in the inquiry search server. 
     Further, the inquiry search server still takes charge of maintaining some other instant information, including the service evaluation points gotten by each inquiry terminal, a source inquiry search information broadcast table (including IDs of all target inquiry terminals), a record table of the target inquiry terminals (IDs of all the target inquiry terminals answering to a corresponding inquiry search) answering the inquiry terminal, and the number of the inquiry information of the same inquiry terminal (for distinguishing between different inquiry information of the same inquiry terminal). 
     The ID and the inquiry number of the source inquiry terminal are contained in the inquiry request information of the source inquiry terminal received by the inquiry search server. 
     Once the inquiry search server receives from an inquiry terminal an inquiry and a keyword which is a key feature of the target inquiry terminal (an inquiry terminal user capable of answering the inquiry) the user of the source inquiry terminal desires to inquire of, the inquiry search server caches the inquiry request information sent from the source inquiry terminal while searching for relevant information of inquiry terminals matching with the keyword, wherein the relevant information of the inquiry terminals includes personal information of the users of the inquiry terminals and the information updated by the inquiry terminals in real time, and last, then, a preliminary target inquiry terminal group is obtained. 
     In the disclosure, the inquiry search server may obtain the instant geographical location information of an inquiry terminal by conducting an update operation continuously. 
     On the basis that the preliminary target inquiry terminal group is obtained, the inquiry search server selects a final target inquiry terminal to which a broadcast is forwarded to with reference to states of the target inquiry terminals, preferably, the inquiry search server selects an inquiry terminal the receiving cache of which is empty or an inquiry terminal getting more points or an inquiry terminal closer in geographical location to the source inquiry terminal as the target inquiry terminal. By implementing these strategies, the inquiry search server obtains a table of the final to-be-broadcasted target inquiry terminals desired by the source inquiry terminal, the set of the IDs of the target inquiry terminals is presented in the target inquiry terminal table, and the inquiry search server broadcasts the inquiry request of the source inquiry terminal out according to the broadcast table. If there is no target inquiry terminal matching with the keyword of the inquiry terminal, the inquiry search server directly searches for a target inquiry terminal close in geographical location to the source inquiry terminal to broadcast the inquiry request to the target inquiry terminal, and the ID and the inquiry number of the source inquiry terminal are contained in the broadcasted inquiry request information. Here, being close in geographical location to the source inquiry terminal means being close to the home address and/or the current location of the user of the inquiry terminal, and it may be set here that a distance within a distance of 100 m or 500 m is a close distance. 
     In the disclosure, the inquiry request includes, but is not limited to: voice inquiry request, video inquiry request, text inquiry request and the like, and correspondingly, the answer to the inquiry request includes, but is not limited to: voice answer, video answer, text answer and the like. As to a voice inquiry request, the user of the inquiry terminal can record a voice inquiry in real time using the voice recording function of the inquiry terminal and send the recorded voice to the inquiry search server; and as to a video inquiry request, the user of the inquiry terminal can make a video inquiry in real time using the video recording function of the inquiry terminal and send the recorded video to the inquiry search server. As to the answer to an inquiry, the other inquiry terminals may give an answer to the inquiry request of the inquiry terminal by voice or video recording. 
     It should be noted that the inquiry search server itself has a voice recognition function, if the user of the source inquiry terminal initiates an inquiry request in a voice or video manner instead of inputting a keyword, then the voice inquiry search server automatically recognizes information of the voice inquiry or video inquiry of the user of the source inquiry terminal and extracts a keyword for searching for a target inquiry terminal. 
     The inquiry search server may analyze a keyword from relevant information of the inquiry terminal. 
     The ID and the inquiry number of the source inquiry terminal are contained in the answer of the target inquiry terminal received by the inquiry search server, the inquiry search server forwards the answer to the source inquiry terminal according to the ID of the source inquiry terminal contained in the answer, and the inquiry number of the source inquiry terminal is also added in the answer. 
     The inquiry search server statistically records answers of the target inquiry terminals, the record is stored in a record table of inquiry answering terminals (that is, target inquiry terminals); once the number of the answers given by the target inquiry terminals to the inquiry request of the corresponding source inquiry terminal reaches a desirable number applied for by the user of the inquiry terminal, the inquiry search server considers that the current inquiry search service for the source inquiry terminal is completed, then shields subsequent answers to the inquiry of the source inquiry terminal and supports the notification of the acquisition of a desired answer to the other target inquiry terminals having not given no answer to a corresponding inquiry request of the source inquiry terminal. 
     The inquiry search server stores the malicious answers reported by the user of the inquiry terminal for later evidence presentation, meanwhile, the inquiry search server supports the shielding of the logic connection path of a malicious inquiry terminal user. 
     The inquiry search server uniformly accumulates the points of each target inquiry terminal according to the evaluation scores given by the source inquiry terminal, the points are beneficial for the operating company to the make an operation strategy and develop corresponding rewards and punishment measures. 
     The inquiry search server records different types of services initiated by the inquiry terminal, for example, a reward-offered service initiated by the user of the inquiry terminal, to help the operating company make an operation strategy later, thus making it easy for the operating company to supervise and prove the fulfilling of the reward offering to the user of the inquiry terminal. 
     The inquiry search server also accepts a broadcast service initiated by the user of the inquiry terminal aiming at a self-defined group, this broadcast is forwarded according to a group inquiry terminal ID designated by the user of the source inquiry terminal. 
     The inquiry search server sends prompt information to the source inquiry terminal if the source inquiry terminal is not answered for a long time, so as to suggest the source inquiry terminal to modify the keyword. 
     The inquiry terminal provided herein has the following technical features: 
     the inquiry terminal provided herein which may be any existing inquiry terminal device, for example, a telephone, a mobile telephone, a computer or a new inquiry terminal product, supports all existing network access methods, including ordinary telephone network access, xDSL access, passive optical network access and various wireless network accesses, and each inquiry terminal has a unique inquiry terminal identification number (ID) assigned by the inquiry search server. 
     The inquiry terminal has an interface for editing text data via which the user of the inquiry terminal can send a data keyword to the inquiry search server and the personal information of the user of the inquiry terminal is modified, meanwhile, for the user of a mobile inquiry terminal, the inquiry terminal supports a function of automatically reporting the geographical location information of the inquiry terminal to the inquiry search server. 
     The inquiry terminal has a caching function to cache voice inquiry or video inquiry information thereof and the answer information received from a target inquiry terminal and cache when serving as a source inquiry terminal or the inquiry information received from the source inquiry terminal when serving as a target inquiry terminal; meanwhile, once the space occupied by the inquiry information received from the source inquiry terminal is beyond a quota in the receiving cache, the inquiry terminal automatically sends the ‘full’ state of the receiving cache to the inquiry search server to support the inquiry search server to develop a broadcast strategy. 
     The user of the inquiry terminal may initiate an inquiry request to the target inquiry terminals at any time through the inquiry terminal, the user of the inquiry terminal may input a keyword of the target inquiry terminal on the inquiry terminal and submits the keyword to the inquiry search server for the inquiry search server to find a target inquiry terminal group; the content of the inquiry request of the source terminal is recorded in a voice or video manner, and the voice of the user of the target inquiry terminal is converted to a voice signal and stored in the cache of the inquiry terminal; the inquiry terminal submits the inquiry request to the inquiry search server when the network is idle and adds its own ID in the inquiry request, meanwhile, the inquiry terminal supports the assignment of a number to the inquiry request information and the submission of the inquiry request to the inquiry search server along with the number. 
     When serving as a source inquiry terminal, the inquiry terminal has a voice or video coding and noiseless compression function, and correspondingly, when serving as a target inquiry terminal, the inquiry terminal has a voice or video decompression function for restoring the voice or video of the user of the inquiry terminal. Certainly, the inquiry request may be text information. 
     After the target inquiry terminal receives the inquiry request (voice or record here) of the source inquiry terminal forwarded by the inquiry search server, the user of the target inquiry terminal listens to the voice inquiry or watch the inquiry video of the source inquiry terminal, selectively initiates voice or video answering to the inquiry of the source inquiry terminal after confirming himself or herself is capable of answering the inquiry, submits the answer to the inquiry search server, wherein the ID and the inquiry number of the source inquiry terminal are added in the answer, and sends the answer to the source inquiry terminal via the inquiry search server, thereby obtaining desirable information. Certainly, the inquiry request may be text information. 
     Once the target inquiry terminals receive an inquiry request from the source inquiry terminal or receive answer information from target inquiry terminals, these target inquiry terminals will give different prompt sounds and indicate the receiving states of their respective answer information. 
     Initiating an inquiry request or answering a received inquiry request, the inquiry terminal may selectively attach its own ID in the inquiry request or in the answer, the selection signal is submitted to the inquiry search server at the same time and sent to the target inquiry terminal or the source inquiry terminal to shield the display of the ID of the inquiry terminal. 
     For an item indicating that the inquiry has been completed according to a notification received from the inquiry search server, the inquiry terminal is prompted that the corresponding item is invalid or prompted to directly delete the item to save the space of the cache. 
     If the user of the inquiry terminal considers the received answer information useless, the inquiry is then forwarded by the inquiry search server to acquire help from a wider range. For a question the target inquiry terminal is indeed incapable of providing an answer, the user of the source inquiry terminal may selectively delete or keep the inquiry request information on his/her inquiry terminal. 
     The user of the inquiry terminal may report a malicious answer to the inquiry search server and submit the malicious answer to the inquiry search server for latter proof presentation. 
     The user of the source inquiry terminal may mark the answer received from the target inquiry terminal on his/her inquiry terminal and submit the scores to the inquiry search server for point statistics. 
     The inquiry terminal may initiate different types of inquiry requests, the user of the inquiry terminal may initiate a reward-offered service for an emergent question needing a high-quality answer and post a reward amount which can be seen by the user of the target inquiry terminal. 
     The inquiry terminal provided herein also supports grouping the contacts stored in its address book, attaches a group inquiry terminal ID in an inquiry search when initiating the inquiry search and notifies the inquiry search server to broadcast the inquiry to the known group, thereby sending inquiry request information to the members in a group. 
       FIG. 2  is a flowchart illustrating an inquiry method according to an embodiment of the disclosure, and as shown in  FIG. 2 , the method includes the following steps. 
     Step  201 : After receiving an inquiry request from an inquiry terminal, an inquiry search server acquires a keyword related to the inquiry request, determines a given number of other inquiry terminals as a target inquiry terminal group according to the keyword and relevant information of the other inquiry terminals; 
     the given number of other determined inquiry terminals are inquiry terminals potentially capable of answering the inquiry request of the user of the inquiry terminal; 
     the relevant information of the inquiry terminal which is all stored in the inquiry search server includes at least one of the personal information of the user of the inquiry terminal and the information updated by the inquiry terminal in real time; the personal information of the user of the inquiry terminal includes at least one of the name, the gender, the age, the ID card number, the home address, the skilled field, the demand, and the wish of each family member of the user of the inquiry terminal; and the information updated by the inquiry terminal in real time includes at least one of geographical location information, the number of the target inquiry terminals required by the inquiry terminal to be included in the target inquiry terminal group, the number of the answers desired by the inquiry terminal, the idle/busy state of the receiving cache of the inquiry terminal and the points gotten by the inquiry terminal as a target inquiry terminal. 
     Acquiring a keyword related to the inquiry request is as follows: 
     when initiating the inquiry request, the inquiry terminal notifies the inquiry search server of the keyword of the inquiry request; 
     or the inquiry search server analyzes the keyword of the inquiry request from the content of the inquiry request received. 
     Determining a given number of other inquiry terminals as a target inquiry terminal group according to the keyword and relevant information of the other inquiry terminals refers to: 
     matching the keyword with relevant information of the other inquiry terminals, preferentially with an idle inquiry terminal and/or an inquiry terminal getting more points, and determining the final target inquiry terminal group based on the number of the target inquiry terminals required by the inquiry terminal; 
     when there is no inquiry terminal matching with the keyword or the number of the target inquiry terminals fails to meet the requirement of the inquiry terminal, preferentially adding the inquiry terminal close to the home address or the current location of the user of the inquiry terminal into the target inquiry terminal group; 
     alternatively, when there is no inquiry terminal matching with the keyword or the number of the target inquiry terminals fails to meet the requirement of the inquiry terminal, preferentially adding an inquiry terminal getting more points into the target inquiry terminal group; 
     Step  202 : The inquiry search server sends the inquiry request to each inquiry terminal in the target inquiry terminal group; 
     the inquiry search server assigns identification information to each inquiry terminal and sends the received inquiry request to each target inquiry terminal in the target inquiry terminal group according to the identification information of the inquiry terminal; 
     Step  203 : After receiving an answer to the inquiry from a target inquiry terminal, the inquiry search server sends the answer to the inquiry terminal. 
     Here, the inquiry request is a voice or video inquiry request or a text inquiry request, and the answer to the inquiry request may be a voice or video answer or a text answer. 
     In the disclosure, the number of the answers to an inquiry received by the inquiry search server and sent from the inquiry search server to the inquiry terminal is not higher than that desired by the inquiry terminal. 
     In the disclosure, the inquiry search server also receives the evaluation given by the inquiry terminal on an answer and updates the points of the target inquiry terminal giving the answer according to the scores of the evaluation. 
     The essence of the technical solution of the disclosure is further set forth below with reference to specific examples. 
     Example 1: Cell Service 
     When at home, the user of an inquiry terminal may need instant information on the surroundings, for example, the user desires for information on where commodities are sold at a favorable price, where a restaurant providing affordable food can be found or where a house for rent is available, but it is inconvenient to ask information from strangers around, then the user can record his/her question in an audio record or a video manner on his/her inquiry terminal and inputs a keyword ‘nearby’. The user may receive a given number of voice answers from neighbors after a while, in this way, the user of the inquiry terminal obtains desired information. Meanwhile, the user of the inquiry terminal marks the quality of the answers to the inquiry request and submits the scores to the inquiry search server. 
     Example 2: Consult Professionals Such as a Math Teacher

     INDUSTRIAL APPLICABILITY 
     In the disclosure, after receiving an inquiry request from an inquiry terminal, an inquiry search server acquires a keyword related to the inquiry request, determines a given number of other inquiry terminals potentially capable of answering the inquiry of the inquiry terminal as a target inquiry terminal group according to the keyword and relevant information of the other inquiry terminals, and sends the inquiry request to each target inquiry terminal in the target inquiry terminal group. The disclosure realizes a voice-level inquiry and the acquisition of a voice-level answer, thus undoubtedly facilitating the operation of the user of a voice inquiry terminal, and by making a voice record, the user of a voice inquiry terminal can initiate an inquiry or answer an inquiry, which is greatly beneficial to the promotion of the technical solution of the disclosure.
