Abstract

PROBLEM TO BE SOLVED: To provide a message transmission system which can easily transmit an identical message to plural mobile terminals and can arbitrarily specify the mobile terminal of a multi-address object. SOLUTION: Common group identifiers are imparted to plural mobile terminals and correspondence relationships between these group identifiers and calling numbers of the plural mobile terminals belonging to the former are stored as member tables by each of mobile terminals 1a, 1b, 1c, 1d and 1e. Thus, when an arbitrary mobile terminal 1a, 1b, 1c, 1d or 1e receives a multi-address message accompanied by this group identifier, this member table is referred to on the basis of the group identifier, a multi-address message 101 is transmitted to a next transmission destination, and the mobile terminal 1a, 1b, 1c, 1d or 1e which receives the multi-address message 101 transmits the multi-address message 101 accompanyied by this group identifier one after another.

In the message transmission method according to the second embodiment, a new group identifier is assigned to a plurality of mobile terminals not stored in the member table 60, and the new group identifier and mobile terminals belonging to the new group are assigned. The corresponding relationship with the calling number of each mobile terminal 1a, 1b, 1c, 1d
To the mobile terminals 1a, 1b, 1c,
By adding the new correspondence to the member table 60, 1d and 1e can transmit the same message to a plurality of mobile terminals not stored in the member table 60.

According to the second embodiment of the present invention, a new group identifier is assigned to a plurality of mobile terminals that are not stored in member table 60, and the new group identifier and the mobile terminals belonging to the new group are assigned. The correspondence with the calling number is transmitted to each of the mobile terminals 1a, 1b, 1c, 1d and 1e, and each of the mobile terminals adds the new correspondence to the member table 60 and stores the new correspondence in the member table 60. The same message can be transmitted to a plurality of mobile terminals that did not exist.

Embodiment 3 Next, a third embodiment of the present invention will be described with reference to FIGS. 1, 2, 6 and 7. FIG.

In FIG. 6, mobile terminals 1a, 1c, 1e
Is composed of a message header 70 including a source 71, the number of destinations 72, destinations 73a and 73b, and a message body 74.

In FIG. 7, the mobile terminal 1 a has a configuration in which the group corresponding to the member table 60 stored in the group member storage unit 15 does not exist, or the group member storage unit 15 does not exist. FIG. 10 is a sequence diagram illustrating an operation of transmitting the same message to a group including mobile terminal 1a, mobile terminal 1c, and mobile terminal 1e.

Next, the operation of the third embodiment will be described.
This will be described with reference to FIGS. 1, 2, 6 and 7.

First, in order to transmit the same message to the mobile terminal 1c and the mobile terminal 1e, the mobile terminal 1a sets the source 71 of the message header 70 to the mobile terminal 1a and the number of destinations to seven.
2 to 2 and destinations 73a and 73b to mobile terminal 1c, respectively.
And the broadcast message 301 set in the mobile terminal 1e is transmitted to the mobile terminal 1c, and the broadcast message body 74 is stored in the message storage unit 16.

Next, the mobile terminal 1c receives the broadcast message 301 from the mobile terminal 1a, confirms that the source 71 of the message header 70 of the broadcast message 301 is not the own calling number, and stores the message. The message body 74 is stored in the unit 16 and the message body 74 is displayed on the display unit 14. This broadcast message 301
, The own address 73a is deleted from the message header 70, and the number of destinations 72 is decremented by one.
The broadcast message 301 is transmitted to the call number PIDe based on 3b.

Next, the mobile terminal 1e receives the broadcast message 301 from the mobile terminal 1c, confirms that the source 71 of the message header 70 of the broadcast message 301 is not the own calling number, and stores the message. The message body 74 is stored in the unit 16 and the message body 74 is displayed on the display unit 14. This broadcast message 301
The destination 73b is deleted from the message header 70, and the number of destinations 72 is decremented by one, and the number of destinations becomes 0. Therefore, the broadcast message 301 is transmitted to the call number PIDa based on the source 71.

Next, the mobile terminal 1a receives the broadcast message 301 from the mobile terminal 1e, and since the source 71 of the message header 70 of the broadcast message 301 is its own calling number, Know that

In this way, a new group consisting of a plurality of mobile terminals is formed, and the same message is transmitted regardless of the presence or absence of the group member storage unit 15.

The message transmission method according to the third embodiment of the present invention comprises means for transmitting a broadcast message accompanied by call numbers of a plurality of mobile terminals 1a, 1b, 1c, 1d or 1e; By means of transmitting the broadcast message 301 to the mobile terminal if the broadcast message includes the calling number of the mobile terminal, or to the source mobile terminal if the broadcast message does not include the call number. This is a message transmission method for transmitting the same message to an arbitrary plurality of mobile terminals including a mobile terminal having no member table.

In the message transmission method according to the third embodiment, a broadcast message accompanied by a call number of a plurality of mobile terminals 1a, 1b, 1c, 1d or 1e is transmitted, whereby mobile terminals 1a, 1b, 1c, 1d or 1e is the broadcast message 3 with the call numbers of the plurality of mobile terminals.
01, the own call number is deleted from the broadcast message 301, and if the broadcast message 301 includes the call number of the mobile terminal, the mobile terminal is addressed to the mobile terminal.
If not included, the broadcast message 301 can be transmitted to the source mobile terminal, so that the same message can be transmitted to any mobile terminal regardless of the presence or absence of the member table.

According to the third embodiment of the present invention, by transmitting a broadcast message with the call numbers of a plurality of mobile terminals, mobile terminal 1a, 1b, 1c, 1d or 1e can be connected to the plurality of mobile terminals. When a broadcast message 301 with a call number is received, the broadcast message 301
, Delete the self-call number from the mobile terminal, and if the broadcast message includes the call number of the mobile terminal,
If it is not included, the broadcast message 301 can be transmitted to the source mobile terminal, so that the same message can be transmitted to any mobile terminal regardless of the presence or absence of the member table.

[0049]

According to the first aspect of the invention, the same message can be transmitted to a plurality of mobile terminals without using a broadcast control device. Therefore, the system configuration can be reduced and the same message can be transmitted to any mobile terminal. Can send messages.

According to the second aspect, a new group identifier is assigned to a plurality of mobile terminals that are not stored in the member table, and the new group identifier and the call number of the mobile terminal belonging to the new group are assigned. By transmitting the correspondence to each mobile terminal and adding the new correspondence to the member table, each mobile terminal can transmit the same message to a plurality of mobile terminals not stored in the member table.

According to the third aspect of the present invention, by transmitting the broadcast message with the call numbers of the plurality of mobile terminals, when the mobile terminal receives the broadcast message with the call numbers of the plurality of mobile terminals, The self-call number is deleted from the broadcast message, and if the broadcast message includes the call number of the mobile terminal, the call is destined to the mobile terminal.
