The present invention relates to a mobile communications terminal, network device, mobile communications system, information transmitting and receiving method and information transmitting and receiving program.
As mobile communications terminals such as cellular telephones, PHS and the like have become more popular, the users of such mobile communications terminals have become able to receive various types of information regardless of time or place. Specifically, by accessing server devices installed by mobile communications business operators (or server devices connected to mobile communications networks; same below), the users of mobile communications terminals can receive information such as images, music, text and the like stored in such server devices. For example, such techniques are described in “Japanese Patent Application Laid-Open No. 6-161918”, “Japanese Patent Application Laid-Open No. 9-214935”, “Japanese Patent Application Laid-Open No. 10-149309”, “Japanese Patent Application Laid-Open No. 2001-313913” and the like in the Japanese Patent Application Laid-Open Gazette.
With the current active development of information flow, the clear distinction between senders of information and receivers of information has disappeared, so that anyone may be a receiver of information, and may also be a sender of information. For example, in cases where a user who receives information via the internet wishes to send information himself, this user can send his own information to a wide circle of other users by uploading this information into a server device managed by an internet connection business operator or the like. Meanwhile, other users can receive the information sent by the abovementioned user by accessing the server device managed by the abovementioned internet connection business operator and downloading this information.
However, in view of such points, the following problems have been encountered in the abovementioned conventional technology. Specifically, in cases where the users of mobile communications terminals desire to send information, these users must upload this information into a server device provided by a mobile communications business operator, so that the procedure involved is extremely complicated.
Furthermore, in cases where users of mobile communications terminals desire to receive information, the information that can be received is limited to information that has been uploaded into a server device provided by a mobile communications business operator. Accordingly, even if other users of mobile communications terminals have extremely useful information, this information cannot be received by requests from receivers unless the information is uploaded into a server device provided by a mobile communications business operator (self-initiated transmission from senders is possible).
Thus, the abovementioned conventional technology does not offer a high level of convenience in cases where users of mobile communications terminals send or receive information.
Accordingly, it is an object of the present invention to provide a mobile communications terminal, network device, mobile communications system, information transmitting and receiving method and information transmitting and receiving program which solve the abovementioned problems, and which make it possible to afford increased convenience when the users of mobile communications terminals send or receive information.
In order to solve the abovementioned problems, the mobile communications terminal of the present invention comprises first storage means for storing information, first receiving means for receiving transmission requests transmitted from communications terminals for the abovementioned information stored in the abovementioned storage means, and first transmitting means for transmitting the abovementioned information stored in the abovementioned storage means to the abovementioned communications terminals in accordance with the transmission requests for the abovementioned information received by the abovementioned first receiving means.
Furthermore, in order to solve the abovementioned problems, the information transmitting and receiving method of the present invention comprises a first receiving step in which information is stored in the storage means of a mobile communications terminal, and the receiving means of the abovementioned mobile communications terminal receive a transmission request that is transmitted from a communications terminal for the abovementioned information that is stored in the abovementioned storage means, and a first transmitting step in which the transmitting means of the abovementioned mobile communications terminal transmit the abovementioned information stored in the abovementioned storage means to the abovementioned communications terminal in accordance with the transmission request for the abovementioned information received by the abovementioned receiving means.
Furthermore, in order to solve the abovementioned problems, the information transmitting and receiving program of the present invention causes a mobile communications terminal to function as first receiving means for receiving transmission requests transmitted from communications terminals for information stored in the storage means of the abovementioned mobile communications terminal, and as first transmitting means for transmitting the abovementioned information stored in the abovementioned storage means to the abovementioned communications terminals in accordance with the transmission requests for the abovementioned information received by the abovementioned first receiving means.
Since the mobile communications terminal receives transmission requests for information and transmits information stored in the storage means to communications terminals in accordance with the transmission requests for this information, this information can be sent from the mobile communications terminal to other communications terminals without uploading the information into a server device provided by a mobile communications business operator. As a result, increased convenience is afforded when the user of the mobile communications terminal sends information.
Furthermore, in order to solve the abovementioned problems, the mobile communications terminal of the present invention comprises second transmitting means for transmitting transmission requests for information stored in the storage means of other mobile communications terminals to these other mobile communications terminals, second receiving means for receiving the abovementioned information transmitted from the abovementioned other mobile communications terminals in accordance with the transmission requests for the abovementioned information that are transmitted from the abovementioned second transmitting means, and presenting means for presenting the abovementioned information that is received by the abovementioned second receiving means.
Furthermore, in order to solve the abovementioned problems, the information transmitting and receiving method of the present invention comprises a second transmitting step in which the transmitting means of a mobile communications terminal transmits a transmission request for information stored in the storage means of another mobile communications terminal to this other mobile communications terminal, a second receiving step in which the receiving means of the abovementioned mobile communications terminal receive the abovementioned information that is transmitted from the abovementioned other mobile communications terminal in accordance with the transmission request for the abovementioned information that is transmitted from the abovementioned transmitting means, and a presenting step in which the presenting means of the abovementioned mobile communications terminal present the abovementioned information received by the abovementioned receiving means.
Furthermore, in order to solve the abovementioned problems, the information transmitting and receiving program of the present invention causes a mobile communications terminal to function as second transmitting means for transmitting transmission requests for information stored in the storage means of other mobile communications terminals to these other mobile communications terminals, as second receiving means for receiving the abovementioned information transmitted from the abovementioned other mobile communications terminals in accordance with the transmission requests for the abovementioned information that are transmitted from the abovementioned second transmitting means, and as presenting means for presenting the abovementioned information received by the abovementioned second receiving means.
Since transmission requests for information stored in the storage means of other mobile communications terminals are transmitted to these other mobile communications terminals, and information transmitted from the other mobile communications terminals is received and presented in accordance with the transmission requests for this information, this information can be received from other mobile communications terminals without uploading the information into a server device provided by a mobile communications business operator. As a result, increased convenience can be afforded when the user of the mobile communications terminal receives information.
Furthermore, in order to solve the abovementioned problems, the network device of the present invention comprises third receiving means for receiving transmission requests that are transmitted from communications terminals for information stored in the storage means of a mobile communications terminal, specifying means for specifying the abovementioned mobile communications terminal on the basis of the transmission requests for the abovementioned information received by the abovementioned third receiving means, third transmitting means for transmitting a transmission request for the abovementioned information to the abovementioned mobile communications terminal specified by the abovementioned specifying means, fourth receiving means for receiving the abovementioned information that is transmitted from the abovementioned mobile communications terminal in accordance with the transmission request for the abovementioned information that is transmitted by the abovementioned third transmitting means, and fourth transmitting means for transmitting the abovementioned information that is received by the abovementioned fourth receiving means to the abovementioned communications terminals.
Since transmission requests for information stored in the storage means of a mobile communications terminal are received from communications terminals and transmitted to the mobile communications terminal, and information transmitted from the mobile communications terminal in accordance with the transmission requests for information is received and transmitted to the communications terminals, this information can be sent to the communications terminals from the mobile communications terminal without passing through a sever device provided by a mobile communications business operator. As a result, increased convenience can be afforded when the user of the mobile communications terminal sends or receives information.
Furthermore, in order to solve the abovementioned problems, the mobile communications system of the present invention comprises the abovementioned network device, the abovementioned mobile communications terminal (on the information transmitting side) and communications terminals, and in this mobile communications system, the abovementioned network device receives transmission requests for the abovementioned information that are transmitted from the abovementioned communications terminals, transmits the transmission requests for the abovementioned information to the abovementioned mobile communications terminal, receives the abovementioned information that is transmitted from the abovementioned mobile communications terminal, and transmits the abovementioned information to the abovementioned communications terminals.
By constructing a mobile communications system equipped with one of the abovementioned network devices, one of the abovementioned mobile communications terminals (on the transmitting side) and other communications terminals, it is possible to send information from the mobile communications terminal to the other communications terminals without using the intermediaryship of a server device provided by a mobile communications business operator.

First, a mobile communications system constituting an embodiment of the present invention will be described with reference to the attached figures. Furthermore, the mobile communications system of the present embodiment includes a network device and mobile communications terminal constituting embodiments of the present invention.
First, the construction of the mobile communications system of the present embodiment will be described. FIG. 1 is a structural diagram of the mobile communications system of the present embodiment. The mobile communications system 10 of the present embodiment is constructed so that this system is equipped with cellular telephones 12 and 14 (mobile communications terminals) and a network device 16. Furthermore, for convenience, the cellular telephone 12 will be described as the cellular telephone on the information transmitting side, and the cellular telephone 14 will be described as the cellular telephone on the information receiving side. However, there may also be cases in which the cellular telephone 12 is the cellular telephone on the information receiving side, and conversely, there may be cases in which the cellular telephone 14 is the cellular telephone on the information transmitting side. The respective constituent elements will be described in detail below.
The cellular telephone 12 is constructed so that this cellular telephone is equipped with a storage part 17 (first storage means), an attribute adding part 18 (adding means), a request receiving part 20 (first receiving means) and an information transmitting part 22 (first transmitting means).
Information of various types such as images, music, text and the like is stored as files in the storage part 17. Furthermore, the storage part 17 can create directories based on instructions from the user. FIG. 2 is a diagram which shows the directory construction of the storage part 17. For example, as is shown in FIG. 2, subordinate directories titled “images”, “music” and “mail” have been created by the user of the cellular telephone 12 under a root directory provided beforehand in the storage part 17. Furthermore, the image information of “image 1” and “image 2” is stored as image files (e.g., JPEG, GIF, BMP or MPEG files) in the “image” directory, and the music information of “music 1” and “music 2” is stored as music files (e.g., MIDI or WAV files) in the “music” directory. Furthermore, the text information of “mail 1” is stored as a text file in the “mail” directory. Moreover, the directory construction of the storage part 17 can be freely altered by the user of the cellular telephone 12. For example, a “still image” directory and a “moving image” directory can be further created under the “image” directory shown in FIG. 2, so that a hierarchical directory structure can be constructed.
Furthermore, a file titled “list of stored information” is stored in the root directory. FIG. 3 is a diagram which shows the construction of the file titled “list of stored information”. As is shown in FIG. 3, a list of the information (files) stored in the storage part 17, and attribute information such as transmission permission information, forwarding permission information, editing permission information, copyright information, data size and the like, for the respective information (files) stored in the storage part 17, are contained in the file titled “list of stored information”.
Here, the term “transmission permission information” refers to information that indicates whether or not it is permitted to transmit the information in question to other cellular telephones (e.g., the cellular telephone 14), i.e., whether or not it is permitted to disclose the information in question to other parties. Furthermore, the term “forwarding permission information” refers to information that indicates whether or not information that has been transmitted to other cellular telephones (e.g., the cellular telephone 14) may be further forwarded from these other cellular telephones to still other cellular telephones (e.g., cellular telephones other than the cellular telephone 14), i.e., whether or not this information may be secondarily distributed. Furthermore, the term “editing permission information” refers to information that indicates whether or not information that has been transmitted to other cellular telephones (e.g., the cellular telephone 14) may be edited in these other cellular telephones. Moreover, the term “copyright information” refers to information that indicates whether or not the information in question is copyrighted.
The attribute adding part 18 adds attribute information regarding attributes of information such as images, music, text and the like stored in the storage part 17 to this stored information. To describe this in greater detail, the attribute adding part 18 adds transmission permission information, forwarding permission information, editing permission information and copyright information to the respective information (files) such as images, music, text and the like stored in the storage part 17, and records such attribution in the file titled “list of stored information”. Furthermore, the attribute adding part 18 detects the data size of respective information (files) such as images, music, text and the like stored in the storage part 17, and records this data size in the file titled “list of stored information”.
The request receiving part 20 receives transmission requests that are transmitted from the cellular telephone 14 via the network device 16 for the list of information that is stored in the storage part 17 of the cellular telephone containing this request receiving part 20 (i.e., the cellular telephone 12). The request receiving part 20 also receives transmission requests that are transmitted from the cellular telephone 14 via the network device 16 for information stored in the storage part 17 of the cellular telephone containing this request receiving part 20 (i.e., the cellular telephone 12).
The information transmitting part 22 transmits the list of information stored in the storage part 17 of the cellular telephone containing this information transmitting part 22 (i.e., the cellular telephone 12) to the cellular telephone 14 via the network device 16 in accordance with transmission requests for the list of information that are received by the request receiving part 20. Furthermore, the information transmitting part 22 transmits information stored in the storage part 17 of the cellular telephone containing this information transmitting part 22 (i.e., the cellular telephone 12) to the cellular telephone 14 via the network device 16 in accordance with transmission requests for information that are received by the request receiving part 20.
In this case, the information transmitting part 22 refers to transmission permission information that is contained in the file titled “list of stored information” that is stored in the storage part 17, and in cases where the transmission of the information requested by the cellular telephone 14 is permitted, the information transmitting part 22 transmits this information to the cellular telephone 14. On the other hand, in cases where the transmission of this information is not permitted, the information transmitting part 22 does not transmit this information to the cellular telephone 14.
Furthermore, the information transmitting part 22 refers to forwarding permission information contained in the file titled “list of stored information” that is stored in the storage part 17, and in cases where forwarding of the information requested by the cellular telephone 14 is permitted, the information transmitting part 22 transmits this information to the cellular telephone 14 in a state of allowing the forwarding of the information. On the other hand, in cases where forwarding of this information is not permitted, the information transmitting part 22 transmits this information to the cellular telephone 14 after working the information into a state that does not allow forwarding.
Furthermore, the information transmitting part 22 refers to editing permission information contained in the file titled “list of stored information” that is stored in the storage part 17, and in cases where editing of the information requested by the cellular telephone 14 is permitted in the cellular telephone 14, the information transmitting part 22 transmits this information to the cellular telephone 14 in a state of allowing the editing of the information. On the other hand, in cases where editing of the information is not permitted in the cellular telephone 14, the information transmitting part 22 transmits this information to the cellular telephone 14 after working the information into a state that does not allow editing of the information.
Furthermore, the information transmitting part 22 refers to copyright information contained in the file titled “list of stored information” that is stored in the storage part 17, and if the information requested by the cellular telephone 14 is copyrighted, the information transmitting part 22 transmits information indicating this to the cellular telephone 14.
Here, the cellular telephone 12 can perform communications while moving. Specifically, the cellular telephone 12 can transmit the abovementioned information to the cellular telephone 14 while moving. However, in cases where the cellular telephone 12 transmits the abovementioned information while moving, there may be instances in which the cellular telephone 12 enters a region in which the reception electromagnetic wave strength is small, so that the call is cut off before the transmission of the abovementioned information is completed. The cellular telephone 12 is prepared for such cases. That is, specifically, whenever the call to the cellular telephone 14 is cut off in a state in which the transmission of the abovementioned information to the cellular telephone 14 is incomplete, the information transmitting part 22 again makes a call connection when the cellular telephone 12 returns to a region in which the reception electromagnetic wave strength is large, and re-initiates the transmission of the abovementioned information to the cellular telephone 14.
The attribute adding part 18, request receiving part and information transmitting part 22 of the cellular telephone 12 are realized by installing a program (information transmitting and receiving program) in the cellular telephone 12 in order to realize the respective functions of the abovementioned attribute adding part 18, request receiving part 20 and information transmitting part 22 in the cellular telephone 12. This program may be installed in the cellular telephone 12 beforehand, or may be downloaded from a server via a carrier wave, and then installed.
The cellular telephone 14 is constructed so that this cellular telephone is equipped with a request transmitting part 24 (second transmitting means), an information receiving part 26 (second receiving means), a storage part 28 (second storage means) and an information presenting part 30 (presenting means).
The request transmitting part 24 transmits transmission requests for the list of information stored in the storage part 17 of the cellular telephone 12 to the cellular telephone 12 via the network device 16.
