The CPU 21, RAM 23, storage unit 24, operation unit 25, display unit 26, and bus 29 have the same configurations as the CPU 11, RAM 13, storage unit 14, operation unit 15, display unit 16, and bus 19 provided in the information terminal 1, respectively. However, the ROM 22 stores communication terminal identification information MID for identifying the communication terminal 2. The communication unit 27 includes a first communication unit 271 and a second communication unit 272. The first communication unit 271 performs communication with the communication endpoint 171A included in the communication unit 17 of the information terminal 1. The first communication unit 271 has the same configuration as the communication end point 171A of the information terminal 1, and thus the description thereof is omitted. The second communication unit 272 performs communication with the communication network 3. The second communication unit 272 is a wireless communication circuit compliant with, for example, IMT-2000. The second communication unit 272 functions as a reception unit that receives document data sequentially transmitted from the communication unit 57 of the management server 5 described later via the communication network 3.

That is, this user terminal device is a user terminal device having receiving means for receiving document data and display means for displaying the received document data. A communication terminal 2C, which is a wired LAN terminal, is connected to the communication end point 171C. Although this wired LAN terminal is not provided with a CPU, ROM, or the like, a MAC (Media Access Control) address is assigned as communication terminal identification information MID. Further, the communication network 3 </ b> C that communicates with the communication terminal 2 </ b> C directly communicates with the management server 5 without going through the network 4.

(A-4: Configuration of management server)
FIG. 4 is a block diagram illustrating an example of the management server 5. The CPU 51, ROM 52, and RAM 53 have the same configuration as the CPU 11, ROM 12, and RAM 13 provided in the information terminal 1, respectively. The CPU 51 is a discriminating unit that discriminates the transmission destination, transmission source, and type of document data, and a specifying unit that identifies the type of communication network corresponding to the discriminated transmission destination, transmission source, and type of the document. The CPU 51 also functions as a storage control unit that controls writing to and reading from the storage unit 54 and a transmission control unit that controls transmission by the communication unit 57. The communication unit 57 communicates with the network 4. The communication unit 57 is a transmission unit that sequentially transmits document data to each of a plurality of user terminal devices via one of a plurality of types of communication networks 3 via the network 4. The storage unit 54 is a large-capacity storage unit such as a hard disk drive, and stores a program read by the CPU 51. In addition, the storage unit 54 stores a terminal registration table 541 and a priority table 542.

(A-5: Configuration of terminal registration table)
FIG. 5 is a diagram illustrating an example of the terminal registration table 541. As shown in the figure, the terminal registration table 541 includes user identification information for identifying a user and any one of “department manager”, “general employee”, “section manager”, “section chief” indicating the user's title, etc. And the communication terminal identification information MID of the communication terminal 2 owned by the user are described in association with each other.
For example, the user (hereinafter referred to as user U1) indicated by the user identification information “U1” is “general employee”, and the user U1 indicates “M1” indicating a mobile phone as communication terminal identification information MID, and a wireless LAN terminal. “W1” is associated with “B1” indicating a wired LAN terminal. The user U2 is a “manager”, and the user U2 is associated with “M2” indicating a mobile phone and “B2” indicating a wired LAN terminal. The symbol “-” in the figure represents “not applicable”. Therefore, there is no wireless LAN terminal associated with the user U2. Note that the communication terminal identification information MID is actually a telephone number “090-xxx-xxxx” in the case of a mobile phone, and actually in the case of a wireless LAN terminal and a wired LAN terminal. Is the respective MAC address.

(A-6: Configuration of priority table)
FIG. 6 is a diagram illustrating an example of the priority table 542. As shown in the figure, “priority of transmission destination”, “position of transmission source”, and “type” are described in the priority table 542 as attributes of document data to be transmitted. Here, the “position of the transmission destination” indicates the position of the user to whom the document data is sent, and the “position of the transmission source” indicates the position of the user on the side of sending the document data. The “type” indicates the purpose and use of the document data. The “type” of the document data that needs to be approved by an authorized approver is “approved”. The “type” of document data for sharing information between them is “information sharing”. The “type” of the document data for unilaterally presenting information from the transmission source user to the transmission destination user is “notification”. In the priority table 542, priorities are described according to the contents of the attribute of the document data. This priority is a numerical value that determines which of the mobile phone, wireless LAN terminal, and wired LAN terminal should be used as the communication terminal 2, and the higher the numerical value, the higher the priority. For example, if the “position of the transmission destination” is “department manager”, the priorities are such as the cellular phone “2”, the wireless LAN terminal “0”, and the wired LAN terminal “1”. Therefore, in this case, the CPU 51 of the management server 5 preferentially uses the communication terminal 2 in the order of mobile phone → wired LAN terminal → wireless LAN terminal. When each of the communication terminals 2 described above is specified, the corresponding type of the communication network 3 is specified. That is, the priority table 542 includes a plurality of combinations for each combination of document attribute and communication network type. Storage means for storing the attribute of this document and the types of a plurality of communication networks in association with each other by storing a numerical value for specifying any one of the communication network types.

(B: Operation)
Next, operation | movement of the communication system 9 which is one Embodiment of this invention is demonstrated.
FIG. 7 is a sequence diagram illustrating an example of an upload operation in the communication system 9. Here, uploading means that document data is transmitted from the information terminal 1 to the management server 5. First, the user U1 operates the information terminal 1-1 that is the information terminal 1 owned by the user U1, and gives an instruction to transmit the document data to another user. Then, the CPU 11 of the information terminal 1-1 describes the user identification information indicating the transmission destination and the user of the transmission source and the character string indicating the type at the position such as a predetermined header of the document data. . Then, the CPU 11 of the information terminal 1-1 has a communication terminal 2A-1, which is a mobile phone connected via the communication unit 17, a communication terminal 2B-1, which is a wireless LAN terminal, and a communication terminal 2C-, which is a wired LAN terminal. 1 is requested to establish a communication path (step S101). The CPU 11 of the information terminal 1-1 accepts responses to these requests from each communication terminal 2, and performs communication through the communication path established earliest. Here, the signal indicating the establishment of the communication path is sent from the communication terminal 2B-1 earliest (step S102). Then, the information terminal 1-1 receiving this ignores the signal indicating communication establishment sent from the other communication terminal 2 and sends the document data to the communication terminal 2B-1 (step S103). The communication terminal 2B-1 sends the received document data to the management server 5 through the established communication path (step S104). When the transmission of the document data is completed, the management server 5 sends a signal indicating that to the communication terminal 2B-1 (step S105), and the communication terminal 2B-1 sends this signal to the information terminal 1-1 (step S105). S106). Thereby, the upload of the document data in the communication system 9 is completed.

FIG. 8A and FIG. 8B are sequence diagrams illustrating an example of a download operation in the communication system 9. Here, download means that document data is transmitted from the management server 5 to the information terminal 1. Hereinafter, document data A in which “U2” as the transmission destination, “U1” as the transmission source, and “approval” as the type will be described with reference to FIGS.
The CPU 51 of the management server 5 examines the document data A received in step S104, and specifies user identification information indicating the transmission destination and transmission source, and a character string indicating the type of the document data A (step S201). Further, the CPU 51 refers to the terminal registration table 541 to identify the post of the transmission destination user to which the document data A is sent and the post of the transmission source user to which the document data A is sent. Then, the CPU 51 extracts the priority of each communication terminal 2 corresponding to each of “position of transmission destination”, “position of transmission source”, and “type” of the document data A, and totals them. (Step S202).

  FIG. 9A shows the total result. Since the transmission destination of the document data A is the user U2, the “position of the transmission destination” is the “department manager”. The priority of each communication terminal corresponding to this is “2-0-1” in the order of mobile phone-wireless LAN terminal-wired LAN terminal. Since the transmission source of the document data A is the user U1, the “position of the transmission source” is “general employee”. The priority of each communication terminal corresponding to this is “0-1-1” in the order of mobile phone-wireless LAN terminal-wired LAN terminal. Since the “type” of the document data A is “approved”, the priority of each corresponding communication terminal is “2-0-0” in the order of mobile phone—wireless LAN terminal—wired LAN terminal. When the CPU 51 sums up these priorities, the total value becomes “4-1-2” in the order of mobile phone—wireless LAN terminal—wired LAN terminal. Therefore, the CPU 51 sets the priority of the communication terminal 2 in the order of the mobile phone → the wired LAN terminal → the wireless LAN terminal, that is, the communication terminal 2A-2 → the communication terminal 2C-2 → the communication terminal, according to the total priority. It determines in order of 2B-2 (step S203). The CPU 51 refers to the terminal registration table 541, specifies the respective communication terminal identification information MID of the communication terminal 2A-2, the communication terminal 2B-2, and the communication terminal 2C-2 of the user U2 as the transmission destination, and priorities An attempt is made to transmit the document via the communication network 3 corresponding to the communication terminal 2 having a high level. Here, as shown in FIG. 5, since “−” is described as a symbol indicating the wireless LAN terminal associated with the user U2 in the terminal registration table 541, the CPU 51 of the management server 5 determines that the user U2 It is determined that no wireless LAN terminal is assigned to the communication terminal 2B-2, and the communication terminal 2B-2 is deleted from this priority order. When the document cannot be transmitted, that is, when the number of times the communication path has failed to be established or the elapsed time from this request has reached a predetermined condition, the communication terminal 2 having the next highest priority order. An attempt is made to transmit this document via the communication network 3 corresponding thereto. Here, since the communication terminal 2 with the highest priority is a mobile phone, the CPU 51 of the management server 5 requests the communication terminal 2A-1 corresponding thereto to establish a communication path (step S204). Receiving this, the communication terminal 2A-1 notifies the management server 5 that the communication path has been established (step S205).

  The CPU 51 of the management server 5 transmits the document data A to the communication terminal 2A-2 that has established the communication path via the communication unit 57 (step S206), and the communication terminal 2A-2 passes through the corresponding communication network 3. The document data A is transmitted to the information terminal 1-2 (step S207). That is, the communication unit 57 of the management server 5 is a transmission unit that transmits a document via the type of communication network 3 specified by the CPU 51. When the user U2 operates the operation unit 15 of the information terminal 1-2 to browse the received document data A and performs an editing operation, the CPU 11 of the information terminal 1-2 responds to the editing operation by the CPU 11 of the information terminal 1-2. Document editing for changing A is performed (step S208). When the completion of document editing is notified by the instruction of the user U2, the CPU 11 transmits the edited document data A to the communication terminal 2A-2 (step S209). The communication terminal 2A-2 transmits the received edited document data A to the management server 5 (step S210).

Next, document data B in which “U3” is described as the transmission destination, “U1” as the transmission source, and “information sharing” as the type will be described with reference to FIGS. 8B and 9.
The processes in steps S301 and S302 are the same as the processes in steps S201 and S202 described above. The CPU 51 of the management server 5 refers to the terminal registration table 541, specifies the post of the transmission destination user to which the document data B is sent, and the post of the transmission source user to which the document data B is sent. The priority of each communication terminal corresponding to these is extracted from the degree table 542 and totaled (step S302).

  FIG. 9B shows the total result. Since the transmission destination of the document data B is the user U3, the “position of the transmission destination” is “general employee”. The priority of each communication terminal corresponding to this is “0-1-1” in the order of mobile phone-wireless LAN terminal-wired LAN terminal. Since the transmission source of the document data B is the user U1, the “position of the transmission source” is “general employee”. The priority of each communication terminal corresponding to this is “0-1-1” in the order of mobile phone-wireless LAN terminal-wired LAN terminal. Since the “type” of the document data B is “approved”, the priority of each corresponding communication terminal is “0-1-1” in the order of mobile phone—wireless LAN terminal—wired LAN terminal. Here, when the CPU 51 of the management server 5 sums up these priorities, the total value becomes “0-3-3” in the order of mobile phone-wireless LAN terminal-wired LAN terminal. That is, the priority of the wireless LAN terminal and the priority of the wired LAN terminal are “3”. In this case, the CPU 51 of the management server 5 treats the wireless LAN terminal and the wired LAN terminal with the same priority (step S303). Specifically, both wireless LAN terminals and wired LAN terminals are requested to establish a communication path (step S304), and communication is performed using the earlier established communication path. In this operation example, the communication terminal 2C-3 which is a wired LAN terminal notifies the management server 5 that the communication path has been established earlier than the communication terminal 2B-1 which is a wireless LAN terminal. (Step S305), the CPU 51 of the management server 5 transmits the document data B using the communication path established with the communication terminal 2C-3 (Step S306).

  The communication terminal 2C-3 transmits this document data B to the information terminal 1-3 (step S307). When the user U3 operates the operation unit 15 of the information terminal 1-3 to browse the received document data B and performs an editing operation, the CPU 11 of the information terminal 1-3 receives the document data in accordance with the editing operation. Document editing for changing B is performed (step S308). Then, when the completion of document editing is notified by the instruction of the user U3, the CPU 11 transmits the edited document data B to the communication terminal 2C-3 (step S309). The communication terminal 2C-3 transmits the received edited document data B to the management server 5 (step S310).

  As described above, the management server 5 can transmit the document data to the information terminal 1 via the communication network 3 corresponding to the attribute of the document data. Further, the user of the communication system 9 sets the correspondence between the attribute of the document data and the communication terminal 2 used for the transmission by using the priority table 542, so that the communication network corresponding to the attribute of the document data is set. 3 can be set freely.

(C: Modification)
The above-described embodiment may be modified as follows.
(Modification 1) In the above-described embodiment, “transmission destination title”, “transmission source title”, and “type” are used as the attributes of the document data. However, other attributes of the document data may be used. . For example, by using “transmission destination” or “transmission source” itself as the attribute of the document data, settings unique to the transmission destination or transmission source user of the document data may be made. In addition, as the attribute of the document data, a department to which each user belongs indicated by “transmission destination” or “transmission source” may be used.

(Modification 2) In the above-described embodiment, the information terminal 1 transmits the document data to the management server 5 without determining the priority of the communication terminal 2 at the time of uploading, but the priority of the communication terminal 2 is determined. The communication path may be established based on this. In this case, the storage unit 14 of the information terminal 1 may store a priority table similar to the priority table 542 stored in the storage unit 54 of the management server 5. The CPU 11 of the information terminal 1 extracts “transmission destination”, “transmission source”, and “type” from the document data to be transmitted, refers to this priority table, and sets the priority corresponding to each communication terminal 2. Can be calculated as follows. In this case, the storage unit 14 stores a user registration table in which user identification information and the title of the user are described. Then, the CPU 11 refers to this user registration table and may specify the “transmission destination title” and the “transmission source title” corresponding to the “transmission destination” and the “transmission source” extracted from the document data.

(Modification 3) In the above-described embodiment, a higher priority is associated with a higher priority, but a lower priority may be associated with a higher priority. Further, the communication path may be established using the numerical value indicated by the priority. For example, the communication terminal 2 with the priority “4” may try to establish a communication path up to four times.
Further, instead of the priority table 542, the communication terminal 2 that transmits the document data may be specified using a table that stores the attribute of the document data and the type of the communication terminal 2 in association with each other. In this case, only one type of communication terminal 2 is associated with this table for each combination of “position of transmission destination”, “position of transmission source”, and “type”. The CPU 51 of the management server 5 may refer to this table, specify the type of the communication terminal 2 according to the attribute of the document data, and transmit the document data using this communication terminal 2. That is, the storage unit 54 of the management server 5 may be a storage unit that stores a document attribute including at least a document transmission destination, a transmission source, and a document type in association with a communication network type.
In addition, the combination of “position of destination”, “position of sender”, and “type” may describe all combinations, some combinations may be described, or a plurality of combinations An expression indicating a set of combinations may be described. The expression indicating a set of a plurality of combinations is, for example, a regular expression that is one of methods for expressing a set of character strings with a single character string.

(Modification 4) In the above-described embodiment, the information terminal 1 and the communication terminal 2 are connected to each other to exchange document data with the management server 5 via the communication network 3 and the network 4. However, the information terminal 1 and the communication terminal 2 may be connected in advance, or the information terminal 1 and the communication terminal 2 may be integrally configured. That is, the user terminal device that exchanges document data with the management server 5 includes a receiving unit that receives a document transmitted by the communication unit 57 of the management server 5 and a display unit that displays the received document. If you do. Further, the number of communication terminals 2 connected to the information terminal 1 is not limited to three, and may be two or four or more.

(Modification 5) In the above-described embodiment, when the completion of document editing is notified by a user instruction, the CPU 11 of the information terminal 1 transmits the edited document data to the management server 5 via the communication terminal 2. However, this transmission need not be performed. Further, the CPU 11 may determine whether or not to perform this transmission based on the attribute of the document data. For example, when the “type” of the document is “notification”, the CPU 11 may not send the document edited by the user to the management server 5.

(Modification 6) In the above-described embodiment, the CPU 51 corresponds to each of “destination title”, “sender title”, and “type” of the document data to be transmitted from the priority table 542. The priorities of the communication terminals 2 are extracted and summed, and the priorities of the communication terminals 2 are determined according to the total priorities, but the “position of the transmission destination”, “position of the transmission source”, and “type” ”May be determined according to the priority of the communication terminal 2 corresponding to the combination of“ ”. In this case, the priority table 542 may describe in advance the priority of each communication terminal 2 corresponding to the combination of “transmission destination post”, “transmission post”, and “type”. In addition, the combination of “position of destination”, “position of sender”, and “type” may describe all combinations, some combinations may be described, or a plurality of combinations An expression indicating a set of combinations may be described.
