     [0066]FIG. 7 is a communication sequence diagram relating to Embodiment 1 of the present invention, showing an example of transmitting and receiving among the wrist-worn portable terminal  200 , the portable telephone  100  and the portable telephone company server  500 . First, when the portable telephone  100  starts a telephone conversation process continuously with one of other portable telephones or fixed telephones via the portable telephone company server  500  ( 101 ), the portable telephone company server  500  transmits an advertisement or the like to the portable telephone  100  ( 102 ). Then the portable telephone  100  transfers the advertisement or the like to the wrist-worn portable terminal  200  ( 103 ). The wrist-worn portable terminal  200  notifies the user of the transfer of the advertisement or the like by means of a signal or the like ( 104 ) and displays the advertisement or the like ( 105 ). Then, when a user&#39;s confirmation operation or the like is performed, the wrist-worn portable terminal  200  transmits the result of confirmation to the portable telephone  100  ( 106 ). The portable telephone  100  then sends a request for transmission of the next advertisement or the like to the portable telephone company server  500  ( 107 ), and the portable telephone company server  500  transmits the next advertisement or the like in response to the transmission request ( 108 ).  
     [0067] The portable telephone  100  again transfers the advertisement or the like to the wrist-worn portable terminal  200  ( 109 ). When the confirmation operation or the like is performed, the wrist-worn portable terminal  200  displays the next advertisement or the like ( 110 ). The wrist-worn portable terminal  200  transmits the result of confirmation to the portable telephone  100 ( 111 ). Subsequently, each time the advertisement information is updated, the same steps are repeated. The portable telephone company server  500  to which the confirmation result is transmitted from the wrist-worn portable terminal  200  adds a point or the like to data on the user. According to the result of addition of points, the user is privileged such as to receive a gift or to have telephone conversation with no charge.  
     [0068]FIG. 8 is a flowchart showing a process performed by the wrist-worn portable terminal in Embodiment 1 of the present invention. In wrist-worn portable terminal  200 , when an advertisement is transmitted in the course of telephone conversation, information in the advertisement is displayed (S 100 ) and a confirmation operation is awaited (S 101 ). When the user performs a confirmation operation (when depressing of a button or a certain motion is caused to be detected by the acceleration sensor), consent information is sent to the portable telephone company server  500  through the portable telephone  100  (S 102 ) and information to be displayed is awaited (S 104 ). When the next advertisement is transmitted and received, the process returns to the first step. If no confirmation operation is recognized through a predetermined time period in step S 101 , the connection to the advertisement information management section  507  of the portable telephone company server  500  is severed (S 103 ) and the process is terminated when the telephone conversation is finished.  
     [0069]FIG. 9 is a flowchart showing confirmation operations in the portable telephone company server in Embodiment 1 of the present invention. When the portable telephone company server  500  receives a confirmation information signal transmitted from the wrist-worn portable terminal  200  through the portable telephone  100  (S 200 ), the signal is identified (S 201 ). If the signal is a service information use signal informing that the user is seeing the advertisement, a point is added (S 202 ). In the case of a no-use signal indicating that the advertisement is not seen, no point is added. A determination is then made as to whether the total of points exceeds a predetermined value. If the total of points exceeds the predetermined value, for example, an instruction is issued to send a gift (S 204 ). If the total of points does not exceed the predetermined value, the process ends immediately.  
     [0070]FIG. 10 is a flowchart showing another process performed by the wrist-worn portable terminal in Embodiment 1 of the present invention. In wrist-worn portable terminal  200 , when an advertisement is received during mail receiving processing, information of the advertisement is output as a speech (S 300 ) and a confirmation operation is awaited (S 301 ). When the user performs a confirmation operation (when depressing of a button or a certain motion is caused to be detected by the acceleration sensor), consent information is sent to the portable telephone company server  500  through the portable telephone  100  (S 302 ), the mail contents are displayed, and the next advertisement to be output as a speech is awaited (S 304 ). When the next advertisement is transmitted and received, the process returns to the first step. If no confirmation operation is recognized through a predetermined time period in step S 301 , a confirmation refusal information is transmitted to the advertisement information management section  507  of the portable telephone company server  500  (S 303 ) and the process is terminated when the telephone conversation is finished.  
     [0071] According to the above-described Embodiment 1, a mobile communication infrastructure can be effectively utilized to improve customer service, to provide a new business, and to offer more user-friendly communication service.  
     [0072] Embodiment 2  
     [0073] Embodiment 2 differs from Embodiment 1 in that timing of advertisement is performed by the portable telephone company server  500 . Embodiment 2 will be described with respect to the points of difference from Embodiment 1, and the description for the same components and processing will not be repeated.  
     [0074]FIG. 11 is a communication sequence diagram relating to Embodiment 2 of the present invention, showing an example of transmitting and receiving among the wrist-worn portable terminal  200 , the portable telephone  100  and the portable telephone company server  500 . First, the portable telephone  100  starts a telephone conversation process continuously with one of other portable telephones or fixed telephones via the portable telephone server  500  ( 201 ). The portable telephone company server  500  starts measuring a lapse of time ( 202 ) and transmits an advertisement or the like to the portable telephone  100  ( 203 ). Then the portable telephone  100  transfers the advertisement or the like to the wrist-worn portable terminal  200  ( 204 ). The wrist-worn portable terminal  200  notifies the user of the transfer of the advertisement or the like by means of such as a signal ( 205 ) and displays the advertisement or the like ( 206 ).  
     [0075] When the portable telephone company server  500  recognizes a lapse of a predetermined time from the transmission of the first advertisement, it newly starts measuring a lapse of time ( 207 ), and transmits the next advertisement or the like to the portable telephone  100 ( 208 ). Then the portable telephone  100  transfers the advertisement or the like to the wrist-worn portable terminal  200  ( 209 ). The wrist-worn portable terminal  200  notifies the user of the transfer of the advertisement or the like by means of such as a signal and displays the advertisement or the like ( 210 ). Subsequently, each time the advertisement information is updated, the same steps are repeated.  
     [0076] According to the above-described Embodiment 2, the user can easily obtain new service information such as advertisements without performing a confirmation operation.  
     [0077] Embodiment 3  
     [0078] Embodiment 3 differs from the above-described Embodiments 1 and 2 in that service information of such as an advertisement is accumulated on the service information provider side, and that the portable telephone company server accesses a service information provider company server of such as an advertisement to transmit service information such as an advertisement to the portable telephone side as occasion arises.  
     [0079]FIG. 12 is a diagram showing the network configuration of a service information provision system using a portable telephone in Embodiment 2 of the present invention. In this network system, a portable telephone  100  and a wrist-worn portable terminal  200  can transmit and receive data to and from each other by means of a small wireless device (not shown). The portable telephone  100  is connected to a portable telephone communication network  300  via a base station  400  to communicate with one of other portable telephones and fixed telephones (not shown). A portable telephone company server  500  is connected to the portable telephone communication network  300 . The portable telephone company server  500  controls portable telephone communications in accordance with a communication protocol and transmits service information. The portable telephone company server  500  is connected to an advertisement provider company server  700  through the Internet  600 . The advertisement provider company server  700  manages advertisements as service information, and transmits an advertisement to the wrist-worn portable terminal  200  through the portable telephone  100  according to an instruction from the portable telephone company server  500  to enable the wrist-worn portable terminal  200  to output the advertisement in the form of, such as a display while the portable telephone  100  is operated for telephone conversation or the like.  
     [0080]FIG. 13 is a diagram showing the hardware configuration of the advertisement provider company server of the present invention. This advertisement provider company server  700  has a CPU  701 , an I/F  702 , a ROM  703 , and a RAM  704 . The CPU  701  performs overall processing of the server by executing various programs. The I/F  702  is a communication interface. The ROM  703  and the RAM  704  store programs or the like executed by the CPU  701 . Specifically, the RAM  704  stores service information such as advertisements.  
     [0081]FIG. 14 is a diagram showing the configuration of functional components of the service information provision system in Embodiment 3 of the present invention. The configuration of functional components of each of the portable telephone  100 , the wrist-worn portable terminal  200  and portable telephone company server  500  is the same as that in Embodiment 1, and the description for it will not be repeated. However, the communication control section  509  of the portable telephone company server  500  controls communication with the advertisement provider company server  700  or the like.  
     [0082] The advertisement provider company server  700  has main sections for realizing a function for enabling the portable telephone company server to access the server on the service information provider side, in which service information such as advertisements is accumulated, to transmit service information such as an advertisement to the portable telephone side as occasion arises. That is, the advertisement provider company server  700  has, as its sections for realizing this function, a communication control section  705  for controlling communication with the portable telephone company server  500 , a data recognition section  706  which makes a decision to transmit advertisement data through the portable telephone company server  500  when, such as a request for transmission of an advertisement is sent from the portable telephone  100 , an advertisement information management section  707  for managing advertisement information, and an advertisement information database (DB)  708  for accumulating advertisement information under the management of the advertisement information management section  707 .  
     [0083]FIG. 15 is a communication sequence diagram relating to Embodiment 3 of the present invention, showing an example of transmitting and receiving among the wrist-worn portable terminal  200  the portable telephone  100 , the portable telephone company server  500 , and the advertisement provider company server  700 . First, the portable telephone  100  starts a telephone conversation process continuously with one of other portable telephones or fixed telephones via the portable telephone server  500  ( 301 ). During this process, the portable telephone company server  500  sends a request for transmission of an advertisement or the like to the advertisement provider company server  700  ( 302 ), and the advertisement provider company server  500  transmits an advertisement or the like to the portable telephone company server  500  in response to the transmission request ( 303 ). Then the portable telephone company server  500  transmits the advertisement or the like to the portable telephone  100  ( 304 ). The portable telephone  100  transfers the advertisement or the like to the wrist-worn portable terminal  200  ( 305 ).  
     [0084] The wrist-worn portable terminal  200  notifies the user of the transfer of the advertisement or the like by means of such as a signal ( 306 ) and displays the advertisement or the like ( 307 ). When a user&#39;s confirmation operation or the like is performed, the wrist-worn portable terminal  200  transmits the result of confirmation to the portable telephone  100  ( 308 ). The portable telephone  100  then sends a request for transmission of the next advertisement or the like to the portable telephone company server  500  ( 309 ), and the portable telephone company server  500  sends a request for transmission of the next advertisement or the like to the advertisement provider company server  700  ( 310 ). The advertisement provider company server  500  transmits the next advertisement or the like in response to the transmission request( 311 ). Then the portable telephone company server  500  transmits the advertisement or the like to the portable telephone  100  ( 312 ), and the portable telephone  100  transfers the advertisement or the like to the wrist-worn portable terminal  200  ( 313 ). When the confirmation operation or the like is performed, the wrist-worn portable terminal  200  displays the next advertisement or the like ( 314 ), and transmits the result of confirmation to the portable telephone  100  ( 315 ). Subsequently, each time the advertisement information is updated, the same steps are repeated.  
     [0085] The portable telephone company server  500  to which the confirmation result has been transmitted from the wrist-worn portable terminal  200  adds a point or the like to data on the user, as in Embodiment 1. According to the result of addition of points, the user is privileged such as to receive a gift or to have telephone conversation with no charge.  
     [0086] In Embodiment 3 described above, it is not necessary for the portable telephone company server  500  to accumulate advertise information, so that the resources at the portable telephone company server  500  can be effectively utilized.  
     [0087] In a case where the service information is such as a quiz or a questionnaire, it is not necessary for the user to answer it during a telephone conversation. Quiz or questionnaire data may be temporarily stored in a memory and the user may answer it (input an answer) after the telephone conversation. A reply to such service information may be manually transmitted each time. However, it is not necessary to immediately transmit the reply. For example, the reply may be stored in a memory and transmitted at the time of the next telephone conversation.  
     [0088] Advertisements may be transmitted periodically at several times in one day, for example, such as in the morning, at midday and in the evening as well as during telephone conversation. If the amount of data of service information such as an advertisement is large, it may be displayed by being scrolled. Further, the timing of switching of an advertisement or the like may have, for example, a cycle of 30 seconds. If a confirmation operation is performed within a certain time period (e.g., within 10 seconds) after receiving each advertisement, the charge for a length of telephone conversation before or after it is reduced to zero (or discounted, or a point is added).  
     [0089] At the time of confirmation with respect to a speech advertisement, the user may be asked to answer a quiz corresponding to the contents of the speech advertisement such that it is possible to ascertain from the answer whether the user has listened to the advertisement. The effectiveness of an advertisement can be improved by this method. The charge for telephone conversation may be reduced to zero if the answer is correct, and the user may be required to pay the charge if the answer is incorrect. Also, at the time of acquisition of a pay content (road traffic jam information or a weather forecast), the user may obtain the content with no charge if the user answers a questionnaire or sees an advertisement.  
     [0090] According to the present invention, as described above, a mobile communication infrastructure is effectively utilized to improve customer service, to provide a new business, and to offer a more user-friendly communication service.
