Description

The present invention relates to an information processing system, an information processing method, a mobile communication terminal, and a program.

  Recent mobile phone terminals (including PHS) are defined by standards so that SMS (Short Message Service) that can send and receive short messages between mobile phone terminals can be used. Generally, SMS standards differ between the same carriers (operators), and it is often possible to send and receive messages only between mobile phone terminals contracted with the same carrier. However, recently, it is possible to send and receive messages between different carriers by unifying the same standard with multiple carriers, and to send and receive messages to fixed terminals such as personal computers by supporting Internet e-mail. It can be used widely.

  FIG. 3 is a block diagram of an information processing system that can use SMS corresponding to electronic mail on the Internet. The electronic mail distributed via the Internet line 301 is transmitted to the MMS-Relay server 302 managed by the carrier. Here, the MMS-Relay server 302 determines the destination from the header information in the electronic mail, and temporarily stores the electronic mail in the mail box 303 prepared for each destination. Then, the MMS-Relay server 302 notifies the SMS center server 304 of the terminal information (MSISDN) of the mobile phone terminal 305 and the e-mail in order to notify the mobile phone terminal 305 corresponding to the destination of the content of the email. Notify information (email sender information, subject, etc.). The SMS center server 304 can create an SMS message from the notified information and push it to the mobile phone terminal 305. When the mobile phone terminal 305 receives the SMS message and the contents are correctly confirmed, the delivery service is completed by returning an Acknowledgment message to the SMS center server 304. Transmission / reception of messages and the like between the SMS center server 304 and the mobile phone terminal 305 is performed via a network 306 including connection by wireless communication.

As this type of technology, in Patent Document 1 (WO 2004/098137 pamphlet), a mail server that has received a message causes an SMS center to send a reception notification to the mobile phone terminal. In response to the reception notification, the mobile phone terminal requests digest information of the message from the mail server, and the mail server transmits the digest information to the mobile phone terminal. The mobile phone terminal presents the digest information to the user, and can acquire the message for each part based on the user's operation input according to the digest information. As a result, the message can be transmitted efficiently, which can contribute to the reduction of unnecessary traffic.
International Publication No. 2004/098137 Pamphlet

  However, the above technique has room for improvement in the following points. Since the message that can be transmitted by the mobile phone terminal is set to a predetermined amount of data (maximum 140 octets), the data amount will be exceeded especially when the e-mail is converted and transmitted as an SMS message to the mobile phone terminal. . In order to cope with this, when transmitting a message exceeding a predetermined amount of data, the SMS center server divides and transmits the message. The mobile phone terminal on the receiving side receives each of the divided messages, and recombines them when all of them are collected to generate a message having the same content as the message before the division. In this process, in order to prevent the divided message from being delivered, when the mobile phone terminal receives the divided message, it returns an acknowledgment message to the SMS center. The SMS center repeats retransmission of the same message until it receives a confirmation message. As a result, non-delivery of the divided message can be prevented.

  However, when the message retransmitted from the SMS center server and the confirmation message transmitted from the mobile phone terminal are crossed, the message received by the mobile phone terminal is combined and then the retransmitted message is received. Thereafter, since the message to be combined with the retransmitted message is not received, the retransmitted message remains in the mobile phone terminal.

  If this message remains in the mobile phone terminal, it may be combined with other messages by mistake when the mobile phone terminal receives another message that has nothing to do with it. There is sex. Moreover, since the amount of SMS message data is limited and only 256 reference numbers for identifying each message are prepared, another message to which the same reference number is added is sent and the above message is sent. An error is likely to occur.

Then, the information processing method of the present embodiment may include a transmission step of transmitting the data file to which the related information is added in the related information adding step (step S105) to the mobile communication terminal 10 via the network 30 ( Step S106).

  Further, the information processing method of the present embodiment includes a second reception step (step S107) in which the mobile communication terminal 10 receives the data block transmitted from the transmission center server 20, and the received data block and the data block. A temporary storage step (step S108) for storing the reference information in the buffer unit 13 and a combination for generating a combined data file by combining the data blocks to which the same reference information is added among the data blocks stored in the buffer unit 13 A step (step S113), a storage step (step S114) for storing the combined data file generated in the combining step and the reference information corresponding to the combined data file in the storage unit 12, and the reference information acquired from the buffer unit 13.

When the comparison results of the comparison steps do not match (NO in step S110) and the determination results of the determination step match (YES in step S112), the combining step generates a combined data file by combining the data blocks. (Step S113).

  Furthermore, in the information processing method of the present embodiment, when the measurement result of the data amount determination step does not exceed the predetermined data amount (140 octets) (NO in step S103), the data file is not divided and the data file is portable communication You may transmit to the terminal 10 (step S106).

  Furthermore, in the information processing method of the present embodiment, when the comparison result of the comparison step matches (YES in step S110), the matching reference information and the data block to which the reference information is added are erased from the buffer unit 13. One erasing step (step S117) may be provided. After the first erasing step (step S117) is processed, the information processing method of the present embodiment may be terminated.

  Furthermore, when the determination results of the determination steps do not match (NO in step S112), the information processing method of the present embodiment may be terminated.

  Here, the effect of this embodiment will be described. First, when the data processing unit 11 combines a plurality of different data files, the reference information added to each data file is stored in the storage unit 12, and the comparison unit 111 is added to the received data file. The reference information stored in the storage unit 12 and the reference information stored in the storage unit 12 are compared, and the data file can be processed by the method defined in 3GPP: TS 23.040 only when they do not match. As a result, even if a part of the combined data file remains in the mobile communication terminal 10 (buffer unit 13), it is possible to erroneously combine the message with another message to which the same reference information is added. Can be prevented.

  In addition, when a data file that matches the comparison result of the comparison unit 111 is received, the data processing unit 11 may delete the data file from the buffer unit 13. This can also prevent the data file from remaining in the mobile communication terminal 10.

  Further, the data processing unit 11 may delete the reference information from the storage unit 12 after a predetermined time has elapsed since the reference information was stored in the storage unit 12. Thus, after a predetermined time has elapsed since the reference information is stored in the storage unit 12, a data file having the reference information can be received and a normal process can be executed. As described above, when the information processing system 1 of the present embodiment is used for SMS, there are only 256 pieces of reference information (reference numbers). Therefore, it is impossible to process immediately unless the reference information stored in the storage unit 12 is cleared. End up. The predetermined time is calculated from the total number of reference information and the communication utterance frequency. In this embodiment, it is considered sufficient to provide about several tens of seconds to several hundreds of seconds.

  Furthermore, since the present embodiment conforms to 3GPP: TS23.040, the processing method so far is not affected, and the reliability can be improved without degrading the communication performance.

  As mentioned above, although embodiment of this invention was described with reference to drawings, these are the illustrations of this invention, Various structures other than the above are also employable.

  For example, the storage unit 12 and the buffer unit 13 included in the mobile communication terminal 10 are described as separate components, but may be realized using different storage areas in the same storage device.

  In the present embodiment, the information processing system that can be used for SMS is described, but the present invention is not limited thereto. For example, it may be used in communication between fixed terminals, or may be used in a mobile communication terminal excluding a mobile phone terminal or PHS.

It is a block diagram of the information processing system which concerns on embodiment of this invention. It is a flowchart of the information processing method which concerns on embodiment of this invention. It is a block diagram of the information processing system which can utilize SMS corresponding to the electronic mail of the internet.
