1. Technical Field
The present invention relates to an apparatus and method for mediating between questioners and answerers in a consultancy service using mobile phones.
2. Description of Related Art
In the conventional art, printed matter, in the form of, for example, information exchange magazines, is used to mediate between questioners, who are persons who have questions, and answerers, who are persons who can provide answers to questions. In a case where, for example, an information exchange magazine is used as a medium by questioners and answerers, answerers provide to publishers of information exchange magazines information on a knowledge area (field) about which they can act as answerers, such as a sport(s), skiing, golf, and so on; city area information, such as Daikanyama, Ginza, and so on. They also provide with their knowledge area (field) information, contact information to be used by questioners to reach answerers, and which may be in the form of addresses, facsimile numbers, telephone numbers, names, and so on. All of this information is published by the publishers to which it is provided in information exchange magazines. Questioners who buy the information exchange magazines, select answerers who offer information under fields relevant to their questions by referring to information provided in the magazines; and contact selected answerers by mail, facsimile, telephone, and so on. In this way, questioners and the answerers are able to communicate with one another.
However, communication mediated through printed matter is subject to a number of problems. Firstly, the process of purchase of printed matter followed by manual selection of answerers referring to information in printed matter is both time-consuming and complicated. Further, in the case that, for example, a questioner has an urgent question, for example, in a case that s/he wishes to know a location of a nearby restaurant when already outside, it may not be physically possible for the questioner to purchase suitable printed matter; or, having purchased printed matter, a questioner may not be able to find any relevant information on answerers in time.
Further, due to the nature of printed matter, after answerers provide their information, namely, information on a field about which they can provide answers, along with information for reaching them, to a publisher of printed matter, it may take a relatively long period of time for the printed matter to be published. Moreover, there is a risk that personal information such as addresses, which answerers must make public in printed matter as contact information for questioners, may be misused. Consequently, persons may be dissuaded from publishing contact information in information exchange magazines, even though they may have the knowledge and experience to provide a service as an answerer.
The present invention is aimed to provide, as a means to overcome problems explained above, a mediation method for consultation and a mediation apparatus for the method, which enable questioners to easily raise questions at any time and in any location, which also enable answerers to quickly register themselves as answerers without complicated registration work, and which protect the privacy of questioners and answerers.

An embodiment of the present invention will be explained below with reference to figures. The following embodiment is a mere example and should not be interpreted as limiting the scope of invention; the present invention is open to a variety of modifications available within the technical scope of the concept of the invention.
A. The Configuration of the Whole System
The mobile phone 9 and the mobile phone 10 are able to connect to the mobile packet communication network 5, and to receive packet communication services provided by the mobile packet communication network 5. The mobile phone 9 and the mobile phone 10 are also able to connect to the mobile telecommunication network 6, and to receive mobile telecommunication services provided by the mobile telecommunication network 6. For simplicity of explanation, only the mobile phone 9 and the mobile phone 10 are shown in the figure, although many mobile phones are able to connect to the mobile packet communication network 5 and the mobile telecommunication network 6.
The mobile phone 9 and the mobile phone 10 are provided with: a wireless communication unit for communicating with base stations (not shown) of the mobile packet communication network 5 and the mobile telecommunication network 6; an audio input-output unit for voice communications; a display unit, which is provided with a liquid crystal display and so on, for displaying texts and pictures in its display; a manipulation unit, which is provided with a ten key pad and so on, for a user to provide the mobile phone his/her instructions; and a microcomputer for controlling the other components of the mobile phone 9 and the mobile phone 10. The microcomputer has a memory which stores a browser program for sending and receiving text data, picture data, audio data, etc. and for displaying these data in the display unit. The microcomputer follows instructions of the browser program and receives information such as screen data of Home Pages etc. from a contents server (not shown) connected to the mobile packet communication network 5, via the mobile packet communication network 5, in a CHTML (Compact Hyper Text Markup Language) format, and displays the received information on its display unit. The microcomputer also follows instructions of the browser program and sends information corresponding to a user's instructions to the contents server, via the mobile packet communication network 5.
In the mediation consultancy service in the present invention, consultancy services on all matters, which are provided to questioners by answerers using mobile phones 9 and mobile phones 10, are mediated. Hereafter, for the sake of description, mobile phones 9 will be supposed to be owned by answerers and mobile phones 10 will be supposed to be owned by questioners.
B. The Mediation Center Apparatus
A configuration of a mediation center apparatus 1 will be explained below by referring to
The registration/inquiry unit 2, after it receives an answerer registration request from a mobile phone 9 owned by an answerer via the mobile packet communication network 5, enables the display unit of the mobile phone 9 to display dialogue screens for answerer registration by sending necessary data in CHTML format to the mobile phone 9 via the mobile packet communication network 5, and requests an owner of the mobile phone 9 to input data required for answerer registration. Also, the registration/inquiry unit 2, after it receives data required for answerer registration from the mobile phone 9 via the mobile packet communication network 5, writes the received data in a new record of the answerer database unit 8 (hereafter, this operation will be referred to as “registration”), and enables the display unit of the mobile phone 9 to display a screen to notify completion of registration by sending necessary data in CHTML format to the mobile phone 9 via the mobile packet communication network 5.
In addition to the process described above relating to answerer registration, the registration/inquiry unit 2 can alter and delete contents already registered in the answerer database unit 8; and it can send contents already registered in the answerer database unit 8 to a mobile phone 9 for the answerer's inquiry. When the registration/inquiry unit 2 carries out these processes for amendment, deletion, and inquiry of registered contents, it also enables the mobile phone 9 to display dialogue screens by sending necessary data in CHTML format to the mobile phone 9, and performs interactive communications with an owner of the mobile phone 9.
In the Mediation Consultancy System of the present invention, an owner of a mobile phone 9 can notify the mediation center apparatus 1 whether the owner is ready to receive questions. Consequently, a questioner is prevented from calling an answerer when it is not convenient for the answerer. When the registration/inquiry unit 2 receives information which shows whether an answerer is ready to receive questions, it writes the information in a record, corresponding to the mobile phone 9, of the answerer database unit 8. In such a case, the registration/inquiry unit 2 also enables the mobile phone 9 to display a dialogue screen which contains software buttons corresponding to “possible to receive questions” and “not possible to receive questions” by sending necessary data in CHTML format to the mobile phone 9. Consequently, the owner of the mobile phone 9 can send to the registration/inquiry unit 2 information which shows whether s/he is ready to receive questions. Regarding this process, instead of using software buttons mentioned above, certain keys in the manipulation unit of the mobile phone 9 can be assigned to send information indicating whether an answerer is ready to receive questions.
The retrieval process unit 3, after it receives a request for a service for a questioner in Mediation Consultancy System in the present invention, from a mobile phone 10, which is owned by a questioner, via the mobile packet communication network 5, extracts, from the answerer database unit 8, information relating to answerers or answerer groups who can match the request, and provides the mobile phone 10 with a result of the extraction. More concretely, after the retrieval process unit 3 receives a request for a service from the mobile phone 10, it requests the owner of the mobile phone 10 to input extraction condition information which is required for extracting information relating to answerers, by sending necessary data in CHTML format to the mobile phone 10 via the mobile packet communication network 5. The extraction condition information concerns, for example, field of question, charge rate, reply rate, and so on. When the retrieval process unit 3 receives extraction condition information from the mobile phone 10, it extracts, from the answerer database unit 8, answerers or answerer groups who can match the extraction condition information, and enables the display unit of the mobile phone 10 to display information on the extracted answerers or answerer groups, such as nicknames, charge rates, and reply their rates, by sending necessary data in CHTML format to the mobile phone 10. At the same time, the retrieval process unit 3 requests the owner of the mobile phone 10 to select one or more answerers from the extracted answerers or answerer groups and to send a result of the selection to the retrieval process unit 3. When the retrieval process unit 3 receives, from the mobile phone 10, the information showing one or more answerers whom the owner of the mobile phone 10 selected, it retrieves information of the one or more answerers from the answerer database unit 8, obtains telephone number information from the retrieved information, and sends the telephone number information to the telephone circuit connection unit 4.
The telephone circuit connection unit 4 calls a mobile phone 9, which is owned by one of the answerers retrieved by the retrieval process unit 3, and a mobile phone 10, which is owned by the questioner, via base stations, and if both of the mobile phone 9 and the mobile phone 10 reply to the call, the telephone circuit connection unit 4 establishes a circuit connection for voice communication between the mobile phone 9 and the mobile phone 10. By means of this telephone circuit connection, the owner of the mobile phone 9 and the owner of the mobile phone 10 are enabled have a conversation to exchange questions and answers. Details of this circuit connection process will be explained later.
The evaluation/billing unit 7 calculates bills for questioners and rewards for answerers for voice communications between mobile phones 9 and mobile phones 10 which are established by the telephone circuit connection unit 4. While a connection of voice communication circuit between a mobile phone 9 and a mobile phone 10 is established, the evaluation/billing unit 7 logs connection time of the voice communication circuit between the mobile phone 9 and the mobile phone 10. When a voice communication between an answerer and a questioner is terminated and a connection of voice communication circuit between the mobile phone 9 and the mobile phone 10 is released, the evaluation/billing unit 7 retrieves, from the answerer database unit 8, a record corresponding to the owner of the mobile phone 9, and from the retrieved record, it obtains information required for calculating a bill. Then the evaluation/billing unit 7 calculates a reward for the answerer, namely the owner of the mobile phone 9, and a bill for the questioner, namely the owner of the mobile phone 10, on the basis of the information which the evaluation/billing unit 7 obtained from the record and from a connection time which the evaluation/billing unit 7 logged. A method for performing these calculations will be described later.
Further, after a connection of a voice communication circuit between the mobile phone 9 and the mobile phone 10 is terminated, the evaluation/billing unit 7 sends a voice guidance message to the mobile phone 10, requesting the questioner to input an evaluation on the answerer. One example of such a voice guidance message is “Now, you are requested to evaluate the contents of the answers which you have just received from the answerer on a scale of from 0 and 9. Please push one of the ten keys between 0 and 9 according to your evaluation, after you hear a beep. A larger number means a higher evaluation. If you skip inputting your evaluation, 5 will be registered as your evaluation. . . . (beeping sound)”. When the evaluation/billing unit 7 receives evaluation information responding to the voice guidance from the mobile phone 10 via the mobile telecommunication network 6, it retrieves a record corresponding to the mobile phone 9 owned by the answerer from the answerer database unit 8, and updates information related to evaluation of the answerer in the retrieved record, on the basis of the evaluation information.
The answerer database unit 8 stores various information related to answerers in relation to telephone numbers of mobile phones which are owned by answerers.
Telephone Number UID contains telephone number information of mobile phones 9 which are owned by answerers. Values in this field are written by the registration/inquiry unit 2 when owners of mobile phones 9 seek registration as answerers.
Answerer Name KM contains name information of owners of mobile phones 9. Values in this field are written by the registration/inquiry unit 2 when owners of mobile phones 9 request registrations as answerers or amendment of registered information. Values in this field are used to provide information which is displayed in a display unit of a mobile phone 10 when the retrieval process unit 3 sends information of extracted answerers to a mobile phone 10 owned by a questioner. Values in this field are decided freely by each owner of mobile phone 9, and each answerer can register either his/her real name or his/her nickname.
Password CRI contains password information of owners of mobile phones 9. Values in this field are written by the registration/inquiry unit 2 when owners of mobile phones 9 request registration as answerers, or amendment of registered information. When the registration/inquiry unit 2 receives a request for amendment, deletion, or inquiry of registered information, which are explained above, password information is used to authenticate that a sender of the request is an actual owner of a mobile phone 9. For example, if the registration/inquiry unit 2 receives a request for amendment of registered information from a mobile phone whose registered telephone number is “09012345678”, first, it causes the display unit of the mobile phone 9 to display a dialogue screen to request a password input. Next, when the registration/inquiry unit 2 receives information input as a password from the mobile phone 9, it retrieves a record whose Telephone Number UID value is “09012345678” from the answerer database unit 8, and obtains a Password CRI value of the retrieved record. According to the example shown in
Reply Possibility Flag ACT contains information showing whether each owner of mobile phone 9 is ready to receive questions. Values in this field are written by the registration/inquiry unit 2 when an owner of a mobile phone 9 sends his/her condition information, namely whether it is possible to receive questions, and the registration/inquiry unit 2 receives this information. Reply Possibility Flag ACT can contain a value “0” or “1” , and “0” means that for the owner of the mobile phone 9 it is currently unable to receive questions, and “1” means that for the owner of the mobile phone 9 it is now possible to receive questions. For example, according to
Answer Field MAJ contains information of fields where owners of mobile phones 9 can answer as answerers. Values in this field are written by the registration/inquiry unit 2 when owners of mobile phones 9 seek registration as answerers or amendments of registered information. Field information included in this field is used as an extraction condition when the retrieval process unit 3 extracts information of answerers.
Evaluation Rank RK contains mean values of evaluations which were made by questioners when owners of mobile phones 9 previously provided their services as answerers. As explained above, in the mediation consultancy service in this embodiment, when a voice communication between an answerer and a questioner is terminated, the evaluation/billing unit 7 receives, from the questioner, evaluation information of the answerer. In this embodiment, the evaluation/billing unit 7 receives integers between 0 and 9 as evaluation information from questioners, and it converts the integers into evaluation values in a range of from 1 to 10. Then the evaluation/billing unit 7 retrieves a record corresponding to the mobile phone 9 of the answerer, reads out Evaluation Rank RK value and Real Consultation Case Number SUM value of the retrieved record, calculates a new mean evaluation value using the values read out and the evaluation value newly received, and updates the value of this field with the newly calculated mean evaluation value. More concretely, the following calculation is performed:
{(Evaluation Rank RK value)*(Real Consultation Case Number SUM value)+(new evaluation value)}/{(Real Consultation Case Number SUM value)+1}
This calculation of mean value is for a mean value of all evaluation values obtained in the past, but this value can be a mean of evaluation values obtained in a certain period of time in the past, etc.
Reply Rate RES contains information showing at what percentage each mobile phone 9 replied to connection calls made by the telephone circuit connection unit 4 responding to connection requests from mobile phones 10 owned by questioners. If the telephone circuit connection unit 4 tries to connect a voice communication circuit with a mobile phone 9 owned by an answerer and fails, it retrieves a record corresponding to the mobile phone 9, reads out Reply Rate RES value and Real Consultation Case Number SUM value of the retrieved record, calculates a new reply rate using the following formula, and updates Reply Rate RES value with the newly calculated value:
(Real Consultation Case Number SUM value)/{(Real Consultation Case Number SUM value)/(Reply Rate RES value)*100+1}*100
On the other hand, if the telephone circuit connection unit 4 tries to connect a voice communication circuit with a mobile phone 9 owned by an answerer and succeeds, it retrieves a record corresponding to the mobile phone 9, reads out Reply Rate RES value and Real Consultation Case Number SUM value of the retrieved record, calculates a new reply rate using the following formula, and updates Reply Rate RES value with the newly calculated value:
{(Real Consultation Case Number SUM value)+1}/({(Real Consultation Case Number SUM value)/(Reply Rate RES value)*100+1 }*100
To further explain the formulas above, (Real Consultation Case Number SUM value) shows a number of replies which the mobile phone 9 made in the past, and {(Real Consultation Case Number SUM value)/(Reply Rate RES value)*100}shows a number of connection trials which the telephone circuit connection unit 4 made to the mobile phone 9 in the past. This calculation is for a reply rate of the mobile phone 9 regarding all connection requests in the past, but this value can be a reply rate regarding connection requests in a certain period of time in the past, etc.
Consultation Fee PRI contains information showing a time unit fee of each owner of mobile phone 9, which owners of mobile phones 10 need to pay as a consultation fee, when the owner of mobile phone 9 answers questions made by owners of mobile phones 10. In this embodiment, values contained by Consultation Fee PRI show fees per minute in yen, and the values are calculated and updated by the evaluation/billing unit 7. It is preferable to adopt a calculation method which produces a larger value for this field, namely Consultation Fee PRI, when Evaluation Rank RK value of the same record is larger. Therefore, in this embodiment, the following formula is adopted:
(Consultation Fee PRI value)=(Evaluation Rank RK value)*10
However, a formula used by the evaluation/billing unit 7 for calculating a consultation fee is not limited to the formula above. For example, if it is considered that answerers whose reply rates for consultation requests are higher should be treated better, formulas which produce larger values for Consultation Fee PRI when corresponding Reply Rate RES values are larger, can be adopted. In such a case, answerers whose reply rates are high are rewarded accordingly, leading to an improvement in the overall service. Since Evaluation Rank RK values are in a range of between 1 and 10 in this embodiment, Consultation Fee PRI values are in a range of between 10 and 100. Consultation Fee PRI values are updated by the evaluation/billing unit 7 at the time that it updates Evaluation Rank RK values, since, in this embodiment, Consultation Fee PRI values are calculated using Evaluation Rank RK values.
When a consultation between an answerer and a questioner is finished and a connection of voice communication between a mobile phone 9 and a mobile phone 10 is terminated, the evaluation/billing unit 7 retrieves a record corresponding to the mobile phone 9 and calculates a fee for the mobile phone 10 by multiplying Consultation Fee PRI value of the retrieved record by the figure of connection time in minutes. Hereafter, the fee will be referred to as “consultation fee”.
Further, the evaluation/billing unit 7 calculates rewards for services provided by answerers, which will be paid to owners of mobile phones 9. In this embodiment, the evaluation/billing unit 7 calculates rewards for answerers using the following formula:
(reward)=(consultation fee)*0.9
This means that 10 percent of a consultation fee, which is charged to questioners, is deducted as a commission for mediation by a provider of the mediation consultancy service, and 90 percent of the consultation fee is paid to answerers. The formula used for calculating rewards is not limited to the above formula. Further, conditions, if any, for paying rewards to answerers, such that, for example, only answerers whose total number of consultation cases is 100 or more can receive rewards, can be adopted. Also, the payment method of rewards to answerers is not limited to cash payment. For example, rewards can be given in a form of points, and answerers can exchange their points for goods. Rewards can also be paid by reducing charges for telephone calls made on mobile phones 9 owned by answerers.
Real Consultation Case Number SUM contains numbers showing how many times each owner of mobile phone 9 provided services as an answerer in the past. When a voice communication circuit between an answerer and a questioner is connected, the evaluation/billing unit 7 retrieves a record corresponding to the mobile phone 9, reads out Real Consultation Case Number SUM value, and updates Real Consultation Case Number SUM value with a value which is calculated by adding 1 to the original Real Consultation Case Number SUM value. In this embodiment, Real Consultation Case Number SUM value shows the number of times services were provided in the past, but this value can be a number of times services were provided in a certain period of time in the past, etc.
C. The Operation of Mediation Consultancy System
An explanation of operations of Mediation Consultancy System in this embodiment is given below.
C-1. The Registration of Answerer
First, an operation performed when an owner of a mobile phone 9 registers as an answerer with mediation center apparatus 1 using the mobile phone 9 will be explained with reference to
The owner of the mobile phone 9 connects the mobile phone 9 to the mobile packet communication network 5 by manipulating the ten key pad, etc. in the manipulation unit, and requests the mediation center apparatus 1 for information for answerer registration via the mobile packet communication network 5 (Step S10). More concretely, s/he carries out such an operation by inputting Uniform Resource Locator (URL) for identifying an address in the communication network where there is data of screens for answerer registration in CHTML format, in the mobile phone 9, and sending it to the mobile packet communication network 5.
When the mediation center apparatus 1 receives the request for information for answerer registration from the mobile phone 9, it sends data for answerer registration in CHTML format t o the mobile phone 9 via the mobile packet communication network 5 (Step S20). After the mobile phone 9 receives the information, it is displayed on its screen, which is shown as T1 in
Screen T1 shows items such as “1. New Registration”, “2. Registered Information”. “3. Amendment of Information”, “4. Deletion of Registration”, and “5. Amendment of Status”, and the owner of the mobile phone 9 can move to an operation step corresponding to each item by inputting a number of the item using the key pad of the manipulation unit. “1. New Registration” is to be selected when an owner of a mobile phone 9 newly registers himself/herself as an answerer. The others are to be selected by an owner of a mobile phone 9 who is already registered. “2. Registered Information” is to be selected when an owner of a mobile phone 9 requests present registered information for his/her confirmation. “3. Amendment of Information” is to be selected when an owner of a mobile phone 9 amends present registered information. “4. Deletion of Registration” is to be selected when an owner of a mobile phone 9 deletes present registered information. “5. Amendment of Status” is to be selected when an owner of a mobile phone 9 changes present condition information relating to whether an owner of a mobile phone 9 is ready to receive questions.
Here, as an example, an operation performed in a case that an owner of a mobile phone 9 selects “1. New Registration” will be explained. If key “1” is pressed by the owner of the mobile phone 9 while screen T1 is displayed, the mobile phone 9 sends its information to the mediation center apparatus 1 via the mobile packet communication network 5. When the mediation center apparatus 1 receives the information, it sends data of screens for a new registration menu in CHTML format to the mobile phone 9 via the mobile packet communication network 5. After the mobile phone 9 receives the information, it displays screen T2 shown in
The screen T2 shows many categories of information, such as “1. Literature”, “2. Mathematics”, “3. Science”, and so on. In this example, it also shows “9. Previous Page” and “0. Next Page”, which are used to change pages, since the menu has many pages. The owner of the mobile phone 9 selects, from these fields, a field in which s/he can provide answers, and inputs a corresponding number using the key pad in the manipulation unit. When the number is inputted, the mobile phone 9 displays a screen showing more detailed fields within the selected field. The owner of the mobile phone 9 selects a field and inputs a corresponding number. This operation is repeated until the menu screen shows the owner of the mobile phone 9 selects the most detailed category within a field.
When the owner of the mobile phone 9 selects the most detailed category within a field as explained above, a screen T3 shown in
When the wireless communication unit of the mediation center apparatus 1 receives the registration request information as explained above, it transfers the information to the registration/inquiry unit 2 under control of the microcomputer, and the registration/inquiry unit 2 determines whether the received registration request information contains appropriate information. If information contained in the registration request information has any problems such as, for example, a number of digits of the received telephone number is not enough, the registration/inquiry unit 2 sends data of a screen for an input error message in CHTML format to the mobile phone 9 via the mobile packet communication network 5. The screen has a “Re-registration” software button and a “Cancel” software button. In a case that the owner of the mobile phone 9 selects the “Re-registration” button, the screen T2 is displayed again, and the operation in Step S30 as explained above is repeated. In a case that the owner of the mobile phone 9 selects the “Cancel” button, the new registration operation finishes and a display of the mobile phone 9 returns to its normal state.
If the received registration request information contains all proper information, the registration/inquiry unit 2 adds a new record in the answerer database unit 8, and writes the telephone number, the registration name, and the password, which are contained in the registration request information, in Telephone Number UID, Answerer Name KM, and Password CRI of the new record. Also, it converts the field information contained in the registration request information into a corresponding field name, and writes the converted field name in Answer Field MAJ of the new record (Step S40). After the registration/inquiry unit 2 completes the operation as explained above, it sends data of a screen for a registration completion notice in CHTML format to the mobile phone 9 via the mobile packet communication network 5 (Step S50).
The above operations are performed by the mobile phone 9 and the mediation center apparatus 1 when the owner of mobile phone 9 registers himself/herself as an answerer at the mediation center apparatus 1 using the mobile phone 9. C-2. Operations of Mediation
The following operations are performed when a questioner sends a request to the mediation center apparatus 1 for a mediation service for consultation using a mobile phone 10 in this embodiment, as shown in
When a questioner wants to request a mediation service, the questioner first connects his/her mobile phone 10 to the mobile packet communication network 5 by manipulating its ten key pad, etc., and requests the mediation center apparatus 1 to provide data of menu screens for a mediation via the mobile packet communication network 5 (Step S100). More concretely, s/he carries out such an operation by inputting a URL for identifying an address in the communication network where there is data of menu screens for a mediation in CHTML format, in mobile phone 10 and by sending it to the mobile packet communication network 5.
When the mediation center apparatus 1 receives the request for data of menu screens for a mediation from the mobile phone 10, it sends the data of menu screens for a mediation in CHTML format to the mobile phone 10 via the mobile packet communication network 5 (Step S105). When the mobile phone 10 receives the data, it displays, in its display unit, a screen T4 of
The screen T4 shows many predetermined fields, such as “1. Literature”, “2. Mathematics”, “3. Science”, and so on. Moreover, in this example, it also shows “9. Previous Page” and “0. Next Page” which are used to change pages since the menu has many pages. The owner of the mobile phone 10 selects, from these fields, a field to which his/her question belongs, and inputs a corresponding number using the key pad in the manipulation unit. When the number is inputted, the mobile phone 10 displays a screen showing more detailed fields in the selected field. The owner of the mobile phone 10 selects a field in the screen and inputs a corresponding number of the selected field again. This operation is repeated until the menu screens show fields in the most detailed category and the owner of the mobile phone 10 selects the most detailed category within a field.
When the owner of the mobile phone 10 selects the most detailed category within a field in the menu screens for a mediation as explained above, it displays a screen T5 of
When the wireless communication unit of the mediation center apparatus 1 receives the mediation request information as explained above, it transfers the information to the retrieval process unit 3 under control of the microcomputer, and the retrieval process unit 3 checks if the received mediation request information contains proper information. If information contained in the mediation request information has any problems such that, for example, a number of digits of the telephone number received is not enough, the retrieval process unit 3 sends data of a screen for an input error message in CHTML format to the mobile phone 10 via the mobile packet communication network 5. The screen has a “Re-registration” software button and a “Cancel” software button. In a case that the owner of the mobile phone 10 selects “Re-registration” button, the screen T4 is displayed again, and the operation in Step S110 as explained above is repeated. In a case that the owner of the mobile phone 10 selects the “Cancel” button, the operation of mediation request is finished and the mobile phone 10 displays a screen of its normal state.
If the received mediation request information contains all proper information, the retrieval process unit 3 initially stores the telephone number contained in the received mediation request information (referred to as “the questioner telephone number” hereafter) temporarily. Then the retrieval process unit 3 converts the field information contained in the mediation request information into a corresponding field name, and extracts, from the answerer database unit 8, records whose Answer Field MAJ values match the converted field name. Then the retrieval process unit 3 extracts, from the extracted records, records whose Reply Possibility Flag ACT values are “1”, namely records which are set in a condition of being able to receive questions (Step S115). Then the mediation center apparatus 1 and the mobile phone 10 perform the following operations on the basis of the number corresponding to a way of selecting answerers which is contained in the mediation request information.
In a case that the number corresponding to a way of selecting answerers, which is contained in the mediation request information, is “1 ”, namely “Answerer” is selected, the retrieval process unit 3 initially sorts all of the records which were extracted at Step S115, as explained above, in the descending order of their Evaluation Rank RK values, and stores the sorted set of extracted records (hereafter referred to as “the extracted records 1”) temporarily. Then the retrieval process unit 3 sends data for displaying Answerer Name KM values, Evaluation Rank RK values, and Consultation Fee Rate PRI values (see
In a case that the number corresponding to a way of selecting answerers, which is contained in the mediation request information, is “2” in Step S115 as explained above, namely “Fee Rate Group” is selected, initially the retrieval process unit 3 extracts, from all of the records which were extracted at Step S115, records whose Consultation Fee Rate PRI values (see
In a case that the number corresponding to a way of selecting answerers, which is contained in the mediation request information, is “3” in Step S115 as explained above, namely “Reply Rate Group” is selected, the retrieval process unit 3 initially extracts, from all of the records which were extracted at Step S115, records whose Reply Rate RES values (see
When the retrieval process unit 3 sends Telephone Number UID values (referred to as “the answerer telephone number list” hereafter), the number of maximum call times (hereafter referred to as “the maximum call times”), and the questioner telephone number to the telephone circuit connection unit 4, as explained above, and the telephone circuit connection unit 4 receives the information, the telephone circuit connection unit 4 stores the received information temporarily and starts a telephone circuit connection step (Step S200). Operations of the telephone circuit connection unit 4 in the telephone circuit connection step are explained in the below with reference to flowcharts in
First, the telephone circuit connection unit 4 causes the mobile phone 10 to display a screen T10 shown in
Next, the telephone circuit connection unit 4 judges whether a value of the call counter is the same as or smaller than both of the maximum call times and judges a number of telephone numbers in the answerer telephone number list (Step S215).
In a case that the telephone circuit connection unit 4 judges that the value of the call counter is the same as or smaller than both of the maximum call times, and judges the number of telephone numbers in the answerer telephone number list, first, it counts the same value of the call counter from the top of the answerer telephone number list, and reads out a telephone number. Namely, for example, if the value of the call counter is “3”, the telephone circuit connection unit 4 reads out the third telephone number in the answerer telephone number list (Step S220). Then the telephone circuit connection unit 4 calls a mobile phone 9 whose telephone number was read out via the mobile telecommunication network 6 (Step S225). After the telephone circuit connection unit 4 sends a call on the basis of the read telephone number, it judges whether the target mobile phone 9 responded to the call in a predetermined period of time (Step S230). In a case that the telephone circuit connection unit 4 judges that the target mobile phone 9 responded to the call in the predetermined period of time, it moves to Step S240 as explained below. On the other hand, in a case that the telephone circuit connection unit 4 judges that the target mobile phone 9 did not respond to the call in the predetermined period of time, it cancels the call to the mobile phone 9, reads a value of the call counter, and updates a value of the call counter with a number which is calculated by adding “1” to the original value of the call counter (Step S235). Then the telephone circuit connection unit 4 retrieves, from the answerer database unit 8, a record whose Telephone Number UID value is the same as the telephone number of the mobile phone 9 to which the telephone circuit connection unit 4 sent a call in Step S225, and updates Reply Rate RES value of the retrieved record. Then it moves to Step S215 to try to call the next answerer candidate.
In a case that the target mobile phone 9 responds to the call in the predetermined period of time in Step S230, the telephone circuit connection unit 4 sends an automatic voice guidance to the mobile phone 9 which responded to the call, which indicates that a questioner wants to talk to the owner of the mobile phone 9, and requests him/her to respond if s/he can reply the questioner by pushing a predetermined key (Step S240). One example of such a voice guidance message is “Now, you have a request from a questioner. If you cannot reply to it, please push key “1”. If you stand by without pushing anything, your telephone will be connected to the questioner.” In the following explanation, if an answerer pushes “1”, it means s/he replies, and otherwise, it means s/he does not reply.
Next, the telephone circuit connection unit 4 judges whether key “1” of the target mobile phone 9 was pushed in a predetermined period of time (Step S245). In a case that it judges that key “1” of the target mobile phone 9 was pushed in the predetermined period of time in Step S245, since an answerer who owns the target mobile phone 9 declined to reply intentionally, the telephone circuit connection unit 4 disconnects the telephone circuit with the mobile phone 9 via the mobile telecommunication network 6 (Step S255), and obtains a value of the call counter and updates a value of the call counter with a number which is calculated by adding “1” to the original value of the call counter (Step S260). Then the telephone circuit connection unit 4 retrieves, from the answerer database unit 8, a record whose Telephone Number UID value is the same as the telephone number of the mobile phone 9 whose telephone circuit was disconnected in Step S255, and updates Reply Rate RES value of the retrieved record. Then the telephone circuit connection unit 4 moves to Step S215 to try to call the next answerer candidate.
On the other hand, in a case that the telephone circuit connection unit 4 judges that key “1” of the target mobile phone 9 was not pushed in the predetermined period of time in Step S245, since an answerer who owns the target mobile phone 9 did not decline to reply, the telephone circuit connection unit 4 holds the voice communication circuit connection with the mobile phone 9 via the mobile telecommunication network 6 (Step S250), and calls the mobile phone 10, whose telephone number is the questioner telephone number which was received from the retrieval process unit 3, via the mobile packet communication network 5 (Step S270). Then the telephone circuit connection unit 4 judges whether the mobile phone 10 responded to the call in a predetermined period of time (Step S275).
In a case that the telephone circuit connection unit 4 judges that the mobile phone 10 did not respond to the call in the predetermined period of time in Step S275, since it failed to establish a voice communication circuit connection with the mobile phone 10 of the questioner, it sends a message of apology as an automatic voice guidance message to the mobile phone 9 of the answerer which is held after Step S250 (Step S280), and disconnects the voice communication circuit with the mobile phone 9 which is held (Step S285), and finishes the telephone circuit connection step. One example of such a message of apology is “We express our apology that we failed to call the questioner. After this message ends, the line will be disconnected automatically.”
On the other hand, in a case that the telephone circuit connection unit 4 judges that the mobile phone 10 responded to the call in the predetermined period of time in Step S275, since it succeeded in establishing a telecommunication circuit connection with the mobile phone 10 of the questioner, it brings to notice of the mobile phone 10 of the questioner that it succeeded in connecting to an answerer by an automatic voice guidance message (Step S290). One example of such a message is “We succeeded in connecting to an answerer. Please hold the line.”
After the telephone circuit connection unit 4 sends an automatic voice guidance message in Step S290, it interconnects the established voice communication circuit connection with the mobile phone 10 of the questioner and the voice communication circuit connection with the mobile phone 9 of the answerer held after Step S250. Consequently a voice communication circuit connection between the mobile phone 10 of the questioner and the mobile phone 9 of the answerer via the mobile telecommunication network 6 is established, and the questioner and the answerer are enabled to have a conversation (Step S295). Then the telephone circuit connection unit 4, from the answerer database unit 8, retrieves a record whose Telephone Number UID value is the same as the telephone number of the mobile phone 9 with which the telephone circuit connection unit 4 established a voice communication circuit connection in Step S295, and updates Reply Rate RES value of the retrieved record. Moreover, the telephone circuit connection unit 4 sends information of the telephone number of the mobile phone 9 of the answerer, with which it established a voice communication circuit connection in Step S295, and the telephone number of the mobile phone 10 of the questioner, to the evaluation/billing unit 7. When the evaluation/billing unit 7 receives the information of the telephone numbers, it stores the information temporarily, and starts to log the connection time.
On the other hand, in Step S215, in a case that the telephone circuit connection unit 4 judges that the value of the call counter is larger than the maximum call times or more than the number of telephone numbers in the answerer telephone number list, it causes the display unit of the mobile phone 10 of the questioner to display a screen T11 shown in
With reference to
When the telephone circuit connection unit 4 establishes the voice communication circuit connection between the mediation center apparatus 1 and the mobile phone 10 as explained above, the evaluation/billing unit 7 stops counting the connection time which it continued and stores the result of the counting temporarily, and at the same time, it sends an automatic voice guidance message which requests for an evaluation input relating to the answerer (Step S140). One example of such a message is “Now, you are requested to evaluate the contents of the answers which you have just received from the answerer in 10 steps between 0 and 9. Please push one of the ten keys between 0 and 9 according to your evaluation after you hear a beep. A larger number means a higher evaluation. If you skip inputting your evaluation, 5 will be registered as your evaluation. . . . (beeping sound)”.
If the questioner pushes a key in the manipulation unit of the mobile phone 10 responding to the automatic voice guidance, a tone signal corresponding to the pushed key is sent from the mobile phone 10 to the evaluation/billing unit 7 via the mobile telecommunication network 6 (Step S145). When the evaluation/billing unit 7 receives the tone signal, it stores an evaluation value corresponding to the tone signal temporarily. If the evaluation/billing unit 7 does not receive any valid tone signal in a predetermined period of time, it stores the default value “6” temporarily as an evaluation value since key “5” corresponds to evaluation value “6” as explained previously. Next, the evaluation/billing unit 7 sends an automatic voice message of operation completion to the mobile phone 10 of the questioner (Step S150), and sends a disconnection request of the voice communication circuit connection to the telephone circuit connection unit 4. When the telephone circuit connection unit 4 receives the disconnection request of the voice communication circuit connection, it disconnects the voice communication circuit connection between the mobile phone 10 and the mediation center apparatus 1 (Step S155).
After Step S155, the evaluation/billing unit 7 retrieves, from the answerer database unit 8, a record whose Telephone Number UID value is the same as the telephone number of the mobile phone 9 of the answerer, which it received from the telephone circuit connection unit 4 in the preceding step, and calculates an amount to be charged to the mobile phone 10 of the questioner and a reward to the user of the mobile phone 9 using Consultation Fee Rate PRI value of the retrieved record and the result of the counting of connect time stored temporarily in the preceding step (Step S160). Information of the bill and the reward calculated here will be sent to a server system (not shown) which manages requests and payment of bills, and handles them together with other telephone bills. Then the evaluation/billing unit 7 calculates a new evaluation rank, a new consultation fee rate, and a new real consultation case number using the evaluation value stored temporarily in the preceding step, Evaluation Rank RK value of the retrieved record, and Real Consultation Case Number SUM value of the retrieved record, and updates Evaluation Rank RK value, Consultation Fee Rate PRI value, and Real Consultation Case Number SUM value of the retrieved record with the calculated values, respectively (Step S165).
These are the operations performed by the Mediation Consultancy System when a questioner requests the mediation center apparatus 1 to provide a mediation service for consultation using a mobile phone 10.
D. Advantages of This Embodiment
According to this embodiment, a questioner can obtain information of answerers who can answer questions of the questioner from among a lot of information of answerers who are registered with the mediation center apparatus, just by sending information of a field to which his/her questions belong to the mobile telecommunication network using his/her mobile phone. Moreover, the questioner can perform voice communications with his/her desired answerers just by selecting them on the basis of the received information of answerers and sending the result of the selection to the mobile telecommunication network using his/her mobile phone. Consequently, the questioner can receive answers for his/her questions by simple operations.
In this embodiment, a questioner can appoint many answerers by person and by group, and in a case that one of the appointed answerers cannot reply, an attempt will be made to automatically establish a voice communication connection with another answerer among the appointed answerers, and the attempt will be repeated. Therefore, the questioner has a high possibility of establishing voice communications with an answerer in a single operation.
Because the mediation consultancy service realized in this embodiment uses mobile phones, a questioner can obtain answers for his/her questions anywhere; even while s/he is walking.
In this embodiment, operations such as an input of field of questions are carried out in dialogue screens made by data in CHTML format using the mobile packet communication network. Therefore, a user can input required data, such as figures, on a screen of their mobile phone, and operations are easy to perform.
In this embodiment, consultation between a questioner and an answerer is performed by voice communications using the mobile telecommunication network. Therefore, both the questioner and answerer can communicate even nuances of their ideas, which are difficult to communicate quickly in other ways, such as by e-mail.
In this embodiment, there is no need for a questioner to register himself/herself in advance. Therefore, a questioner can make use of the mediation consultancy service realized by this embodiment without any complications.
In this embodiment, an answerer can obtain requests of consultation from questioners just by following a simple registration procedure using his/her mobile phone, and can not only utilize his/her knowledge and experiences but also can expect to receive rewards for his/her services as an answerer. Moreover, since mobile phones are used in the mediation consultancy system of this embodiment, an answerer can register himself/herself anytime and anywhere as an answerer and provide his/her services as an answerer.
In this embodiment, the mediation center apparatus calls a mobile phone of a questioner and a mobile phone of an answerer first, and then it connects their lines. Therefore, it can realize direct voice communication without revealing personal information of the questioner and the answerer, such as their telephone numbers. Consequently, both the questioner and the answerer can make use of the service while being sure of their privacy and security.
In this embodiment, there is no complication of fee negotiation because a consultation fee rate of each answerer is offered to a questioner in advance, and the questioner can select answerers by referring to their consultation fee rate. Consequently, both answerers and questioners can make use of the service without hesitation.
In this embodiment, ensuring the quality offered by answerers is important since the answerers have registered on their own. In the mediation consultancy system of this embodiment, however, there is a system by which questioners evaluate the answerers, consultation fee rates are calculated on the basis of the evaluation, and rewards according to the calculated consultation fee rates are paid to the answerers. Therefore, the answerers have an incentive to improve their services, and answerers of low quality are dismissed automatically and only qualified answerers can remain. Consequently, undesirable situations such as payment of high consultation fees for low quality services can be prevented.
E. Variations
In addition to the embodiment explained above, the present invention is open to a variety of modifications in the scope of conception of the invention. The following are some such modifications.
<Modification 1>
In the embodiment explained above, consultation fee rates are calculated according to evaluation ranks recorded in the answerer database unit, but only in the case that an answerer wishes to offer a lower consultation fee rate than the consultation fee rate calculated by the default method, the answerer may set his/her proposed rate as his/her own consultation fee rate.
<Modification 2>
In the embodiment explained above, when an answerer notifies the mediation center apparatus of his/her status whether s/he can accept questions, some charge for using the mobile packet communication network is incurred, since the answerer responds by using keys or software buttons. However, an answerer may notify the mediation center apparatus of his/her status whether s/he can accept questions without any charge by use of a function of dialing a predetermined phone number which the mobile phone of the answerer has. More concretely, on the side of the mediation center apparatus, two telephone numbers for exclusive use are prepared, one of which is used to change Reply Possibility Flag ACT values of the answerer database unit into a status that it is possible to accept questions, and the other of which is used to change Reply Possibility Flag ACT values of the answerer database unit into a status that it is not possible to accept questions. Apparatus connected to these telephone numbers is set to receive only notification of dialing a phone number. Consequently, an answerer can notify his/her phone number to the apparatus only by calling the telephone numbers for exclusive use, and the apparatus can change Reply Possibility Flag ACT values of the answerer database unit, but no charge is incurred.
Moreover, the system may be configured to have a function that an answerer can register in advance the time when s/he can accept questions, when s/he registers himself/herself as an answerer or s/he changes his/her registered contents. By such a function, it becomes unnecessary for the answerer to frequently notify the mediation center apparatus of his/her status as to whether s/he can accept questions, and the system becomes more convenient.
