The bidirectional group identification information transmitter 128-2 transmits the bidirectional group identification information formed in the SMS format to each destination terminal 102 through the SMS server.

3 is a flowchart illustrating a process of providing a bidirectional group message service according to an embodiment of the present invention.

As shown in the figure, a subscriber who wants to receive a group message service first sets up a group by using a group setting means provided by his mobile terminal. After setting the group, the receiver 110 transmits the incoming information and the outgoing information including the called terminal 102 number and the calling number together with the identifier indicating the group message request (S300). The exchange 110 recognizes that the message sent from the originating terminal 101 is a group message request by reading the identifier included in the message, and transmits the incoming information and the originating information to the mailbox device 120 and sends the originating terminal 101. And set a connection call between the mailbox device 120 (S302). The exchange 110 determines whether the group message to be sent by the calling terminal 101 is a video message or a voice message, and performs the procedure of the H.245 protocol in the case of the video message (S304). The mailbox device 120 forms a group message identifier received through the exchange 110, a plurality of called terminal 102 numbers and called terminal 101 numbers in the called information in the form of an SMS message to be sent to the called terminal 102. To store (S306). The SMS message format according to an embodiment of the present invention is the same as the message format generated by the example of FIG. 2A or Example 1, and the calling terminal 101 and the telephone number transmitted to each of the plurality of called terminals 102. The terminal 102 telephone number is as follows.

T (n): Phone number of the nth called terminal 102

T (0): first calling terminal 101 phone number

S (m): Calling number and called number information transmitted in SMS message to mth called terminal 102 (where 0 <m <= n)

S (m) = T (0) + T (1) + T (2) + T (n)-T (m)

That is, the incoming terminal number is excluded.

The mailbox device 120 connected to the caller terminal 101 receives a message from the caller terminal 101 and stores the message in the message storage unit 122 of the mailbox device 120 (S308). The mailbox device 120 attempts to connect a message stored from the originating terminal 101 to the plurality of terminating terminals 102 through the exchange 110 using the Outdialing function, and the exchange 110 is connected to each terminating terminal 102. Check the reception status of and set the call if the reception is possible (S310). The mailbox device 120 transmits a plurality of called and calling numbers including the stored message and the group message of the SMS message format to the called terminal 102 through the connected call (S312). When the destination terminal 102 that has received the message requires a response after checking the message, a response message destination group is generated by an identifier indicating a response of the user interface (response description of the above embodiment), and the mailbox device 120 In addition to the group message identifier indicating that the group message is received from the destination information of the response group and the message group and the originating information of the response originating terminal 101 is transmitted to the exchange (110) (S214). In step S302, the response group message is transmitted by performing the same operation. The response message destination group required for the response message transmission is set by the bidirectional group identification information transmitted from the mailbox device by a program in the terminal. The user interface may add a telephone number of a new called terminal 102 in setting the response message group, and among the telephone numbers of the called terminal 102 in the set group, the user terminal of the called terminal 102 may be selected. It is desirable to include the ability to remove the telephone number from the called group. As described above, as the roles of the calling terminal 101 and the called terminal 102 are changed, it is possible to transmit two-way voice or video messages by repeatedly performing the steps S201 to S207.

4 is a flowchart illustrating a group message sending procedure in the calling terminal 101 according to an embodiment of the present invention.

The originating terminal 101 sets a group (S400) and then requests the exchange 110 to connect a group message call (S402). The exchange 110 receives the request (S404), recognizes the group message by the transmitted group message identifier, and inquires and sets the destination mailbox in the mailbox device 120 (S406). The group message IAM (Initial Address Message) is transmitted to the mailbox device 120 (S408), and the mailbox device 120 transmits a response message ACM (Address Complete Message) to the exchange 110 (S410). The exchange 110 requests a call connection by sending a call progress (CPG) to the mailbox device 120 (S412). In the present embodiment, preferably, the mailbox device 120 performs a procedure of transmitting a voice announcement broadcast to the calling terminal 101 to guide the recording or recording of the message (S414). The mailbox device 120 transmits a response message ANM (Answer Message) to the request of the exchange 110 (S416) and thus the exchange 110 connects a call to the calling terminal 101 (S418). If the group message to be sent by the calling terminal 101 is a video message, the procedure of the H.245 protocol is performed (S420). The calling terminal 101 records or records a group message to be sent (S422) and transmits a message for releasing the call to the switch 110 (S424). The exchange 110 transmits a message REL corresponding to the message to the mailbox device 120 (S426), and the mailbox device 120 transmits a response message RLC to the exchange 110 (S428), and the exchange 110 ) Disconnects the call from the calling terminal (S430).

5 is a flowchart illustrating a procedure of transmitting a voice / video message, calling information, and a plurality of incoming information from a mailbox to a called terminal 102 according to an embodiment of the present invention.

The mailbox device 120 attempts to connect a call to each of the plurality of destination terminals 102 by a broadcast communication and an outdialing function, and receives a message signal (for example, pressing any button of the terminal) of the destination terminal 102. Transmits the stored message from the mailbox device 120 to the destination terminal 102 in a machine-to-man manner. The message broadcast procedure according to an embodiment of the present invention is as follows.

The mailbox device 120 transmits an IAM to the exchange 110 for call connection with the plurality of destination terminals 102 (S500). The exchange 110 sets up a group message call with each destination terminal 102 in response to the received message (S502). The destination terminals 102 transmit a response to the group message call setup to the switch 110 (S504), and the switch 110 transmits a response ACM for the S500 to the mailbox device 120 (S506). The receiving terminal that is not capable of receiving transmits a warning message to the exchange 120 (S508), and the exchange 110 transmits the message to the mailbox device (S506-1). The mailbox device 120 transmits the group message to the plurality of destination terminals 102 that can receive the message (S510). In addition, the two-way group identification information for the outgoing information and the plurality of incoming information formed in the SMS format is transmitted to the plurality of destination terminals 102 through the SMS text message service server and the established call (S512). When the transmission of the group message and the incoming / outgoing call information is completed, the mailbox device 120 disconnects the call from the called terminal 102 (S514). The terminal requiring a response among the called terminal 102 becomes a new calling terminal 101, sets a group called number, and attempts to transmit a group response message (S516 and S518).

Using the existing CDMA mobile communication network, it is possible to expand profits without any significant cost by providing services to send and receive voice group messages in both directions through S / W additional development of existing network devices without developing additional network devices. It can be effective. In addition, video messages can be bidirectionally communicated between designated groups using a WCDMA network, thereby providing a higher quality of service.
