The present application claims priority to Japanese Patent Application JP 2005-251996 filed in the Japanese Patent Office on Aug. 31, 2005, the entire contents of which being incorporated herein by reference.
The present disclosure relates to an application providing system, a portable terminal device, a server device and an application providing method. More particularly, the present disclosure relates to an application providing system in which, if an application corresponding to identification information transmitted from a server device does not exist in a portable terminal device, the server device automatically downloads the identified application to the portable terminal device.
In recent years, a portable terminal device such as a portable phone includes an IC chip capable of carrying out radio communications. Thus, by carrying out a non-contact communication between an external device and the IC chip employed in the portable terminal device, data can be exchanged between the external device and the portable terminal device. Normally, in the course of a communication with an external device, the IC chip employed in the portable terminal device is not capable of communicating with a controller which controls the execution of applications of the portable terminal device. In the course of a communication with the controller, on the other hand, the IC chip is not capable of communicating with an external device.
In order to solve the problem described above, there has been developed a technology whereby the external device transmits information specifying an application to be executed in the portable terminal device and a special command to the portable terminal device and, in accordance with the command, the portable terminal device smoothly activates the application specified by the external terminal for execution in the portable terminal device as disclosed, for example, in Japanese Patent Laid-open No. 2005-108044. When the IC chip employed in the portable terminal device receives the special command, the IC chip transits to a communication state enabling communications with the controller. Then, with the timing of this transition, the controller acquires information received from the external device as the information specifying an application and executes the specified application.
If the application specified by the external device does not exist in the portable terminal device, however, the user may not obtain desired information unless the specified application is downloaded from a web site of a service company to the portable terminal device and executed in the portable terminal device. Thus, in order for the user to obtain the desired information, the user should transmit an e-mail for making a request of the application to the service company or get the URL (Uniform Resource Locator) of the web site of the service company.
Since such an operation making a request for an application is cumbersome, in some cases, the user prefers not to acquire the application and gives up the idea to obtain the desired information. In addition, the user may not be able to acquire the application and receive the desired information because the URL is not inputted correctly. Thus, there is a problem that, if the specified application does not exist in the portable terminal device as described above, the user may not obtain the desired information even if the user can acquire data related to desired information and the service company inevitably loses an opportunity to provide the desired information itself to the user.
According to an embodiment, there is provided an application providing system, portable terminal devices, server devices, application providing method and computer programs capable of determining whether or not a specified application exists in a portable terminal device of the application providing system so as to allow the user to smoothly acquire desired information.
According to an embodiment, there is provided an application providing system connecting a portable terminal device having an IC chip capable of carrying out radio communications to a server device by using a communication network. The application providing system is characterized in that the portable terminal device has: a transmitted message receiver section provided inside the IC chip as a section for receiving a transmitted message including parameter information and the identification information of an application to be executed by the portable terminal device on the basis of the parameter information from the server device; and an application determination section determining as to whether or not the application corresponding to the identification information of the application included in the transmitted message exists in the portable terminal device. The portable terminal device also has: an application transmission request generation section for generating a request for transmission of the identified application from the server device to the portable terminal device in case the application determination section determines that the application corresponding to the identification information included in the transmitted message does not exist in the portable terminal device; and an application storage section for storing an application transmitted by the server device. The application providing system is also characterized in that the server device has: a transmitted message generation section for generating a transmitted message to be transmitted to the portable terminal device; and a transmitted message sender section for transmitting the transmitted message to the portable terminal device in accordance with a request made by the portable terminal device. The server device also has: an application transmission request receiver section for accepting a request transmitted by the portable terminal device as a request for transmission of an application from the server device to the portable terminal device in case the application to be executed in the portable terminal device on the basis of parameter information does not exist in the portable terminal device; an application storage section used for storing applications and application identity information by associating the applications with their respective application identity information each used for identifying the associated one of the applications; and an application sender section for transmitting an application according to a request accepted by the application transmission request receiver section from the portable terminal device to the portable terminal device.
The parameter information is information used for requesting the application of the portable terminal device to display information desired by the user or carry out predetermined processing. The identification information of the application is information used for identifying the application. For example, the identification information is stored in the portable terminal device as information identifiable by a predetermined ID, a URL or the like.
In accordance with the configuration of the application providing system described above, the portable terminal device receiving a transmitted message generated and transmitted by the server device determines as to whether or not an application corresponding to identification information included in the transmitted message exists in the portable terminal device. If the application corresponding to the identification information included in the transmitted message does not exist in the portable terminal device, the portable terminal device issues a request for transmission of the application to the server device. Thus, even if the application corresponding to the identification information included in the transmitted message does not exist in the portable terminal device, a sequence of processes starting with reception of a transmitted message and ending with acquisition of the application can be carried out in a smooth flow without the need for the user to perform cumbersome operations including an inputting a URL or the like. In addition, since the portable terminal device is capable of issuing the request for transmission of the application corresponding to the identification information included in the transmitted message to the server device without the need for the user to perform any operations, it is no longer necessary for the user to know the location, at which the application exists, in advance. In addition, since the user is capable of acquiring an application not existing in the portable terminal device from the server device by merely carrying out a simple operation, the service company providing the user with information is capable of providing information to the user with a higher degree of reliability.
According to an another embodiment, there is provided a portable terminal device connected to a server device by using a communication network and provided with an IC chip capable of carrying out radio communications. The portable terminal device including: a transmitted message receiver section provided inside the IC chip as a section for receiving a transmitted message including parameter information and the identification information of an application to be executed by the portable terminal device on the basis of the parameter information from the server device; and an application determination section for producing a result of determination as to whether or not the application corresponding to the identification information included in the transmitted message exists in the portable terminal device. The portable terminal device also including: an application transmission request generation section for generating a request for transmission of the identified application from the server device to the portable terminal device in case the application determination section determines that the application corresponding to the identification information included in the transmitted message does not exist in the portable terminal device; and an application storage section for storing an application transmitted by the server device.
According to another embodiment, there is provided the portable terminal device with a configuration also including a display section for displaying a result of execution of an application executed on the basis of parameter information included in a transmitted message.
Accordance to the above configuration of the portable terminal device, the portable terminal device receiving a transmitted message generated and transmitted by the server device determines as to whether or not an application corresponding to identification information included in the transmitted message exists in the portable terminal device. If the application corresponding to the identification information included in the transmitted message does not exist in the portable terminal device, the portable terminal device generates a request for transmission of the application from the server device to the portable terminal device, and transmits the request to the server device. Thus, even if the application corresponding to the identification information included in the transmitted message does not exist in the portable terminal device, the application corresponding to the identification information is automatically installed in the portable terminal device from the server device, making it possible to provide information to the user smoothly.
According to another embodiment, there is provided the portable terminal device also including a controller for controlling execution of predetermined applications. In this case, the controller controls the execution of the application, which is corresponding to the identification information of the application, on the basis of the parameter information included in the transmitted message.
According to another embodiment, there is provided the portable terminal device with a configuration in which the IC chip has: a first communication section for carrying out a near-field non-contact communication with an external communication device also connected to the server device by using the communication network; and a second communication section for carrying out a communication with the controller.
In this case, a transmitted message received by the first communication section from the external communication device is sent to the controller via the second communication section. In this configuration, the IC chip switches from a communication between the first communication section and the external device to a communication between the second communication section and the controller and vice versa so as to allow an application to be executed smoothly.
According to another embodiment, there is provided the portable terminal device with a configuration in which the transmitted message includes pieces of identification information used for identifying a plurality of applications according to the specifications of the portable terminal device. In this case, the application determination section determines as to whether or not each of the applications each corresponding to one of the pieces of identification information included in the transmitted message exists in the portable terminal device.
According to another embodiment, there is provided there is provided a server device connected by a communication network to a portable terminal device having an IC chip capable of carrying out radio communications. The server device including: a transmitted message generation section for generating a transmitted message to be transmitted to the portable terminal device as a transmitted message including parameter information and the identification information of an application to be executed by the portable terminal device on the basis of the parameter information; and a transmitted message sender section for transmitting the transmitted message to the portable terminal device in accordance with a request made by the portable terminal device. The server device further including: an application transmission request receiver section for accepting a request transmitted by the portable terminal device as a request for transmission of an application from the server device to the portable terminal device in case the application to be executed in the portable terminal device on the basis of parameter information does not exist in the portable terminal device; an application storage section used for storing applications and application identification information by associating the applications with their respective application identification information each used for identifying the associated one of the applications; and an application sender section for transmitting an application according to a request accepted by the application transmission request receiver section from the portable terminal device to the portable terminal device.
According to another embodiment, there is provided the server device with a configuration in which the application sender section acquires an application according to a request made by the portable terminal device from the application storage section and transmits the application to the portable terminal device.
According to the above configuration, the server device generates a transmitted message including parameter information and the identification information of an application to be executed in the portable terminal device on the basis of the parameter information and transmits the transmitted message to the portable terminal device, in case the application corresponding to the identification information does not exist in the portable terminal device. Thus, even if the application corresponding to the identification information does not exist in the portable terminal device, the portable terminal device is capable of obtaining the application smoothly from the server device without the need for the user to perform cumbersome operations including an inputting a URL or the like. In addition, since the user is capable of acquiring an application not existing in the portable terminal device from the server device by merely carrying out a simple operation, the service company providing the user with information is capable of providing information to the user with a higher degree of reliability.

The server device 200 generates a transmitted message including parameter information and the identification information of an application to be executed by the portable terminal device 100 on the basis of the parameter information. Then, the server device 200 transmits the transmitted message to the portable terminal device 100 via the network 300. The parameter information is typically information used for requesting the application of the portable terminal device 100 to display information desired by the user or carry out predetermined processing. For example, the parameter information is information requesting the application of the portable terminal device 100 to display “Hello” on the display screen. The portable terminal device 100 executes the application corresponding to the identification information of the application included in transmitted message by using the parameter information as input data. For example, by using the parameter information requesting the application of the portable terminal device 100 to display “Hello” on the display screen as input data, the portable terminal device 100 executes the application corresponding to the identification information, displaying “Hello” on the display screen of the portable terminal device 100. As an alternative, the server device 200 holds an application to be provided to the portable terminal device 100 and, in accordance with a request made by the portable terminal device 100, the server device 200 transmits the application to the portable terminal device 100 via the network 300.
The information providing system 10 may include a plurality of server devices 200. There may be different kinds of server devices for different server device functions and different kinds of data held by the server device. For example, there may be an application server device used for storing applications and a download server device for downloading applications. Further, there may be a web server device for providing web pages. These server devices of different kinds may be connected to the network 300.
The portable terminal device 100 receives a transmitted message generated from the server device 200. The portable terminal device 100 then executes the application corresponding to the identification information of the application on the basis of the parameter information included in transmitted message. The portable terminal device 100 determines as to whether or not the application corresponding to the identification information of the application included in the transmitted message exists in the portable terminal device 100. If the result of the determination indicates that the application corresponding to the identification information does not exist in the portable terminal device 100, the portable terminal device 100 generates a request for transmission of the application corresponding to the identification information and transmits the request to the server device 200. In this case, the portable terminal device 100 receives the requested application from the server device 200 and the portable terminal device 100 being able to execute the application. Examples of the portable terminal device 100 are a portable phone, a PDA (personal digital assistant), a portable game device and a watch.
The server device 200 may transmit a transmitted message to a portable terminal device 100 via a reader/writer 400 or the PC 500. The PC 500 may pass on a transmitted message received from the server device 200 to the portable terminal device 100 via a reader/writer 400. The server device 200 may hold a web page displayable on the portable terminal device 100 or the PC 500 and transmit the web page including a transmitted message to the portable terminal device 100 or the PC 500 in accordance with a request made by the portable terminal device 100 or the PC 500 respectively. A web page can be held by the server device 200 or an device other than the server device 200.
The reader/writer 400 is one example of a radio communication device having a function to transmit a transmitted message to a non-contact-communication IC chip existing in a radio-communication range through a radio communication. It is to be noted that the reader/writer 400 may also be embedded in the PC 500 to form an integrated device or connected to the PC 500 as an independent device by using a cable. As another alternative, the reader/writer 400 may be connected to the server device 200 as an independent device through the network 300.
The PC 500 receives a transmitted message transmitted by the server device 200 via the network 300 and gives a command to the reader/writer 400 to send the transmitted message to the portable terminal device 100 by a radio communication. The PC 500 may also receive a web page including parameter information from the server device 200, generate a transmitted message on the basis of the parameter information included in the web page and send the transmitted message to the portable terminal device 100 via the reader/writer 400.
In a case where the reader/writer 400 sends a transmitted message to the portable terminal device 100, the portable terminal device 100 includes a non-contact-communication IC chip capable of carrying out radio communications so that the portable terminal device 100 is capable of performing radio communications with the reader/writer 400 in order to exchange messages. As described above, a transmitted message received by the IC chip of the non-contact-communication type includes the parameter information and the identification information of an application. The IC chip of the non-contact-communication type send the transmitted message to a controller employed in the portable terminal device 100 and, then, the controller executes the application corresponding to the identification information of the application on the basis of the parameter information.
For example, the reader/writer 400 also sends a communication controlling command for controlling the communication with the IC chip of the non-contact-communication type to the portable terminal device 100 along with the transmitted message so as to allow the communication between the IC chip of the non-contact-communication type and the controller of the portable terminal device 100 to be carried out smoothly. In other words, the reader/writer 400 sends the communication controlling command and the transmitted message to the non-contact-communication-type IC chip of the portable terminal device 100 by a radio communication. Receiving the communication controlling command, the IC chip of the non-contact-communication type switches the communication with the reader/writer 400 to a communication with the controller of the portable terminal device 100 and sends the transmitted message to the controller.
The IC chip of the non-contact-communication type can be employed in the portable terminal device 100 by being embedded in the portable terminal device 100 or by being placed on an IC card, which can be inserted into a card slot in the portable terminal device 100. In the latter case, the IC card inserted into a card slot in the portable terminal device 100 carries out radio communications with the reader/writer 400.
The network 300 is a communication-line network for connecting the server device 200 to the portable terminal device 100, the PC 500 or the reader/writer 400 in a state of being capable of carrying out duplex communications between the server device 200 and the portable terminal device 100, the PC 500 or the reader/writer 400. The network 300 can be a radio or wire network. Examples of the network 300 are a public-line network such as the Internet, a telephone-line network or a satellite communication network and a dedicated-line network such as a WAN, a LAN or an IP-VPN.

The transmitted message receiver section 102 is a communication interface such as a communication line, a communication circuit, a communication device or the like. The transmitted message receiver section 102 has a function for receiving a transmitted message from the server device 200. A transmitted message received by the transmitted message receiver section 102 is passed on to the application determination section 104. As described above, a transmitted message received from the server device 200 includes parameter information and the identification information of an application to be executed by the portable terminal device 100 on the basis of the parameter information.
Details of a transmitted message received from the server device 200 are described by referring to
The information used for identifying an application may be dependent on the specifications of the portable terminal device 100. For example, in the portable terminal device 100 conforming to the specifications set by a mobile communication business company D, the application is identified by using the URL 154. In the portable terminal device 100 conforming to the specifications set by mobile communication business companies K and V, on the other hand, the application may be identified by using the ID 156. In this embodiment, both the URL 154 and the ID 156 are included in a transmitted message so that each of the portable terminal devices 100 manufactured by the mobile communication business companies D, K and V with specifications different from each other is capable of determining whether or not an application exists in the portable terminal device 100 as will be described later.
The application determination section 104 has a function to determine whether or not an application corresponding to the identification information of the application included in a transmitted message exists in the portable terminal device 100. For example, the application determination section 104 executes an application corresponding to identification information of the application included in a transmitted message and, if the application is not executed correctly, the application determination section 104 determines that the application does not exist in the portable terminal device 100. Here, correct execution of an application means that the application is executed on the basis of the parameter information to display desired information on the portable terminal device 100 successfully. If the application determination section 104 determines that an application does not exist in the portable terminal device 100, the application determination section 104 provides the result of the determination to the application-transmission request generation section 108.

The application acquisition section 208 is a section for acquiring the application requested by the portable terminal device 100 from the application storage section 210. The application acquisition section 208 supplies the acquired application to the application sender section 212.
The application storage section 210 is a memory used for storing a plurality of applications. A hard-disk drive is a typical application storage section 210. The application storage section 210 can also be provided in a server device other than the server device 200.

The configuration of the PC 500 has been described so far. Next, the configuration of the portable terminal device 100 employing the IC chip of the non-contact-communication type is explained by referring to
The non-contact-communication IC chip 120 receives AC power from the antenna 132 employed by the portable terminal device 100. To put it in detail, when a communication between the non-contact-communication IC chip 120 and the reader/writer 400 is being carried out in a non-contact way, the antenna 132 generates an induction voltage on the basis of a magnetic field generated by the reader/writer 400 as a voltage used for driving the non-contact-communication IC chip 120. The non-contact-communication IC chip 120 operated in this way is then capable of exchanging data with the reader/writer 400 by a radio communication through the antenna 132.
The non-contact-communication IC chip 120 is configured to include typically a rectification circuit, a power generation section, a demodulator, a modulator, a receiver, a sender, a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), an EEPROM (Electrically Erasable Programmable Read Only memory), an encryption engine, an RNG (Random Number Generator) and a CRC (Cyclic Redundancy Check) circuit. In the case of a portable terminal device 100 employing a non-contact-communication IC chip 120, the transmitted message receiver section 102 included in the non-contact-communication IC chip 120 receives transmitted messages transmitted by the server device 200 via the reader/writer 400. The application-transmission request sender section 106 and the application receiver section 110, which are also employed in the portable terminal device 100, are connected to the server device 200 to transmit a request to the server device 200 as a request for transmission of an application from the server device 200 to the portable terminal device 100, and receive the requested application from the server device 200.
The rectification circuit is a circuit for rectifying an AC voltage received from the antenna 132 and supplying a DC voltage obtained as a result of the rectification to the power generation section. The power generation section is a section for generating a power-supply voltage to be used in the non-contact-communication IC chip 120 from the received DC voltage. The demodulator is a component for demodulating a signal received through the antenna 132 into an electrical signal that can be processed in the non-contact-communication IC chip 120 and supplying the electrical signal to the receiver. The modulator is a component for modulating an electrical signal to be transmitted from the non-contact-communication IC chip 120 to the reader/writer 400 via the antenna 132 into a signal that can be transmitted in a non-contact communication.
The CPU is an arithmetic processing device driven to operate by a power-supply voltage generated by the power generation section in the non-contact-communication IC chip 120. The CPU controls all the other components employed in the non-contact-communication IC chip 120. The ROM is a nonvolatile memory used for storing a variety of application programs and an operating system serving as a platform. In the following description, the operating system is abbreviated as OS.
On the other hand, the RAM is a volatile memory used for temporarily storing a variety of application programs and the OS. The EEPROM is a memory used for storing mainly user data. However, the EEPROM can also be used for storing software such as an application program or the OS. In addition, a flash memory can also be used in place of the EEPROM. The encryption engine is a device for carrying out encryption and compounding processes on exchanged data with external device. The RNG is a device for generating a random number to be used as an encryption key in an encryption process. The CRC circuit is a circuit for examining the cyclic redundancy of data received from an external device. That is to say, the CRC checks errors of the data.
A transmitted message received by the non-contact-communication IC chip 120 from the reader/writer 400 is stored in the RAM employed in the non-contact-communication IC chip 120. When a transmitted message received by the non-contact-communication IC chip 120 from the reader/writer 400 is stored in the RAM employed in the non-contact-communication IC chip 120 and a communication is ended, the non-contact-communication IC chip 120 informs the controller 124 that the communication has been ended.
In addition, as described above, the reader/writer 400 may transmit a command besides a transmitted message to the non-contact-communication IC chip 120. Normally, the transmitted command is a command for controlling the communication of the non-contact-communication IC chip 120. In this case, the portable terminal device 100 may include a first communication section and a second communication section. The first communication section is a section for carrying out communications of the non-contact-communication type within short distances between the reader/writer 400 and the non-contact-communication IC chip 120. On the other hand, the second communication section is a section for carrying out communications between the controller 124 and the non-contact-communication IC chip 120. Receiving a command for controlling the communication with transmitted message transmitted by the reader/writer 400 through the first communication section, the non-contact-communication IC chip 120 switches the communication between the reader/writer 400 and the non-contact-communication IC chip 120 to a communication between the controller 124 and the non-contact-communication IC chip 120, supplying the transmitted message to the controller 124 via the second communication section. By switching the communication of the non-contact-communication type within short distances between the reader/writer 400 and the non-contact-communication IC chip 120 to a communication between the controller 124 and the non-contact-communication IC chip 120 in accordance with a command for controlling the communication of the non-contact-communication IC chip 120 in this way, the portable terminal device 100 is capable of executing an application stored in the portable terminal device 100 on the basis of parameter information included in the transmitted message transmitted from the reader/writer 400.
The memory 122 includes a ROM and a RAM. The memory 122 has a function of a memory used for temporarily storing information such as various kinds of data related to controlling processing carried out by the controller 124 and operating programs of the controller 124.
The controller 124 is a section for receiving a transmitted message transmitted by the non-contact-communication IC chip 120 via the second communication section, executing an application corresponding to identification information included in the transmitted message and displaying a result of the execution on a display screen of the portable terminal device 100. More specifically, when the controller 124 receives a transmitted message from the non-contact-communication IC chip 120, the controller 124 passes on the transmitted message received from the non-contact-communication IC chip 120 to the acceptance application 126. The acceptance application 126 then provides parameter information to the application corresponding to the identification information of the application included in the transmitted message. The identification information, such as ID 156 or URL 154, is used by the acceptance application 126 to determine as to whether or not the application corresponding to the identification information has been stored in the application storage section 114.
For example, an application A130 is stored in the application storage section 114 in a state of being identifiable by an ID 156 of “feliCaNW”. The acceptance application 126 searches the application storage section 114 for an application corresponding to the identification information “ID=feliCaNW” of application included in the transmitted message. Since the application A130 has been stored in the application storage section 114, the acceptance application 126 detects the application A130 in the search operation and assigns the parameter information to the application A130. The application A130 is executed on the basis of the parameter information.
As another example, let us assume that an application A130 has been stored in the application storage section 114 in a state of being identifiable by a URL 154 of “http://www.felicanetworks.co.jp/appli.jam”. Also the identification information extracted by the acceptance application 126 from the transmitted message is a URL 154 of “http://www.felicanetworks.co.jp/appli.jam”. In this case, the acceptance application 126 searches the application storage section 114 for an application corresponding to the identification information “http://www.felicanetworks.co.jp/appli.jam” of the application included in the transmitted message. Then the acceptance application 126 provides the parameter information to the application A130 which identification information is “URL=http://www.felicanetworks.co.jp/appli.jam”. As described above, the parameter information will be used by the controller 124 as a basis of execution of the application A130.
The functional configuration of the portable terminal device 100 employing an IC chip of the non-contact-communication type has been explained so far. Next, by referring to a flowchart shown in
To begin with, at the step S102 of the flowchart, the reader/writer 400 transmits a transmitted message. As described above, the reader/writer (R/W) 400 and the non-contact-communication IC chip employed in the portable terminal device 100 are capable of carrying out radio communications with each other in a non-contact way within a near field of about 10 cm. The user holds the portable terminal device 100 at such a location close enough to the reader/writer 400 then the transmitted message can be transmitted to the portable terminal device 100 in a non-contact communication at the next step S104.
Then, at the next step S106, the portable terminal device 100 determines as to whether or not the application corresponding to an application ID included in the transmitted message received in the process of the step S104 as information used for identifying an application exists in the portable terminal device 100. If the determination result at the step S106 indicates that the application corresponding to an application ID included in the transmitted message exists in the portable terminal device 100, the flow of the processing procedure goes on to a step S120. If the determination result at the step S106 indicates that the application corresponding to an application ID included in the transmitted message does not exist in the portable terminal device 100, on the other hand, the flow of the processing procedure goes on to a step S108 at which the portable terminal device 100 determines as to whether or not the application corresponding to a URL included in the transmitted message received in the process of the step S104 as information used for identifying an application exists in the portable terminal device 100.
If the determination result at the step S108 indicates that the application corresponding to a URL included in the transmitted message exists in the portable terminal device 100, the flow of the processing procedure goes on to the step S120. If the determination result at the step S108 indicates that the application corresponding to a URL included in the transmitted message does not exist in the portable terminal device 100, on the other hand, the flow of the processing procedure goes on to a step S110 at which the portable terminal device 100 connects itself to the server device 200. The server device 200 may be perceived as information-providing server device run by a plurality of mobile communication business companies. Thus, the portable terminal device 100 is connected to an information-providing server device that conforms to the specifications of the portable terminal device 100. Let us assume for example that the portable terminal device 100 is connected to an information-providing server device D at a step S112 if the portable terminal device 100 conforms to the specifications of the D mobile communication business company. The portable terminal device 100 is connected to an information-providing server device K at a step S114 if the portable terminal device 100 conforms to the specifications of the K mobile communication business company. The portable terminal device 100 is connected to an information-providing server device V at a step S116 if the portable terminal device 100 conforms to the specifications of the V mobile communication business company. Then, at the next step S118, the portable terminal device 100 automatically installs an application corresponding to application identification information included in the transmitted message, which was originated from the information-providing server device connected to the portable terminal device 100. A process to automatically install an application from the server device 200 is explained as follows. At the beginning of a process to install the application at the step S118, a typical screen display 602 shown in
After the process to automatically install the application downloaded from the server device 200 in the portable terminal device 100 at the step S118 has been completed, the flow of the processing procedure goes on to the step S120 at which the installed application is invoked. As described above, if the determination result the step S106 or S108 indicates that the application corresponding to an application ID included in the transmitted message exists in the portable terminal device 100, the flow of the processing procedure goes on directly to the step S120 at which the application already existing in the portable terminal device 100 is invoked. At the beginning of a process to invoke the application, a typical screen display 606 shown in
After the application has been invoked in the process carried out at the step S120, the flow of the processing procedure goes on to step S122 at which the application is executed on the basis of the parameter information included in the transmitted message. For example, if the parameter information included in the transmitted message requests the application to display “Hello!” on the display screen, the application executed on the basis of the parameter information displays the typical screen display 608 shown in
The flow of the procedure of processing carried out by the information providing system 10 has been described so far. By referring to a flowchart shown in
The flow of information begins with a step S202 at which the portable terminal device 100 transmits a request for a transmitted message to the server device 200. Then, at the next step S204, the server device 200 generates the transmitted message requested by the portable terminal device 100. Subsequently, at the next step S206, the server device 200 transmits the generated message to the portable terminal device 100. The server device 200 may transmit a transmitted message to the portable terminal device 100 even if not requested by the portable terminal device 100.
At the step S206, the portable terminal device 100 receives the transmitted message including parameter information and identification information of the application from the server device 200. Then, at the next step S208, the portable terminal device 100 determines as to whether or not an application corresponding to the identification information included in the transmitted message exists in the portable terminal device 100. If the determination result at the step S208 indicates that the application corresponding to the identification information included in the transmitted message does not exist in the portable terminal device 100, at the next step S210, the portable terminal device 100 generates a request for transmission of the application from the server device 200 to the portable terminal device 100. Then, at the next step S212, the portable terminal device 100 transmits the request generated in the process carried out at the step S210 to the server device 200.
At the step S212, the server device 200 receives the request for transmission of the application from the server device 200 to the portable terminal device 100. Then, at the next step S214, the server device 200 retrieves the application from an application storage section employed in the server device 200 or from another server device holding the application. Subsequently, at the next step S216, the server device 200 sends the application acquired in the process carried out at the step S214 to the portable terminal device 100.
At the step S216, the portable terminal device 100 receives the application from the server device 200. Then, at the next step S218, the portable terminal device 100 stores the received application in a memory. Subsequently, at the next step S220, the portable terminal device 100 invokes the application stored in the process carried out at the step S218 and executes the application on the basis of the parameter information included in the transmitted message. Then, at the next step S222, the portable terminal device 100 displays a result of executing the application on the basis of the parameter information in the process carried out at the step S220 on the display screen of the portable terminal device 100.
The above description has explained the flow of information exchanged between the portable terminal device 100 and the server device 200. By referring to a flowchart shown in
The flowchart begins with a first step S252 at which the PC 500 transmits a request for a transmitted message to the server device 200. Then, at the next step S254, the server device 200 transmits the requested transmitted message to the PC 500. At the step S254, the PC 500 receives the requested transmitted message from the server device 200. Subsequently, at the next step S256, on the basis of the received transmitted message, the PC 500 generates a transmitted message transmissible from the reader/writer 400 employed in the PC 500 to the non-contact-communication IC chip employed in the portable terminal device 100. For example, the PC 500 may embed the transmitted message into data having a predetermined format to generate data of the aforementioned transmitted message exchangeable between the reader/writer 400 employed in the PC 500 to the non-contact-communication IC chip employed in the portable terminal device 100 by radio communication. After generating a transmitted message transmissible from the reader/writer 400 employed in the PC 500 to the non-contact-communication IC chip employed in the portable terminal device 100 in the process carried out at the step S256, at the next step S258, the PC 500 transmits the transmitted message to the non-contact-communication IC chip employed in the portable terminal device 100.
At the step S258, the portable terminal device 100 receives the transmitted message, which includes parameter information and identification information of the application, from the PC 500. Then, at the next step S260, the portable terminal device 100 determines as to whether or not an application corresponding to the identification information of the application included in the transmitted message exists in the portable terminal device 100. If the determination result produced at the step S260 indicates that the application corresponding to the identification information included in the transmitted message does not exist in the portable terminal device 100, at the next step S262, the portable terminal device 100 generates a request for transmission of the application from the server device 200 to the portable terminal device 100. Then, at the next step S264, the portable terminal device 100 transmits the request generated in the process carried out at the step S262 to the server device 200.
At the step S264, the server device 200 receives the request for transmission of the application from the server device 200 to the portable terminal device 100. Then, at the next step S266, the server device 200 retrieves the corresponding application from an application storage section employed in the server device 200 or from another server device holding the application. Subsequently, at the next step S268, the server device 200 sends the application acquired in the process carried out at the step S266 to the portable terminal device 100.
At the step S268, the portable terminal device 100 receives the application from the server device 200. Then, at the next step S270, the portable terminal device 100 stores the received application in a memory. Subsequently, at the next step S272, the portable terminal device 100 invokes the application stored in the process carried out at the step S270 and executes the application on the basis of the parameter information included in the transmitted message. Then, at the next step S274, the portable terminal device 100 displays a result of executing the application on the basis of the parameter information in the process of the step S272 on the display screen of the portable terminal device 100.
The above description has explained the flows of information exchanged among the portable terminal device 100, the server device 200 and the PC 500. In accordance with the application providing system implemented by the embodiment, the portable terminal device determines as to whether or not an application corresponding to identification information of the application included in a transmitted message exists in the portable terminal device, making it possible to smoothly provide the user of the portable terminal device with information desired by the user. Thus, even if the result of the determination indicates that the application corresponding to the identification information included in the transmitted message does not exist in the portable terminal device, the portable terminal device is capable of smoothly acquiring the application from the server device, making it possible to smoothly provide the user of the portable terminal device with information desired by the user without requiring the user to carry out a cumbersome operation such as an operation to input a URL associated with the application. Since an application not existing in the portable terminal device can be obtained from the server device by merely carrying out a simple operation, a service company providing the user with information is capable of providing information to the user with a higher degree of reliability.
