Abstract

The present invention relates to a broadcast message service method, and when a broadcast message is not received due to a user's special situation, by retransmitting the broadcast message at a broadcast message center in response to a request for retransmission of the broadcast message, so that the user does not miss news or useful information. It is. To this end, the present invention is a process of transmitting a broadcast service retransmission request signal for an unreceived broadcast service by a user from the terminal to a broadcast message center when the terminal moves from a region where a broadcast message cannot be received, to the broadcast message retransmission. The request signal includes the broadcast service information designated by the user among the unreceived broadcast services, the broadcast message center, receiving the broadcast service retransmission request signal, and the broadcast message according to the broadcast service information designated by the user; The process is sent to the terminal.

Description

Broadcast message service method {BROADCASTING MESSAGE SERVICE METHOD}

The present invention relates to a broadcast message service method, and more particularly, to a broadcast message service method in which a GSM communication network requests and receives a broadcast message which has not been received, according to a user's convenience.

A general short message service is classified into a point-to-point service and a broadcast service.

The point-to-point service is a service for transmitting a short message (SMS) to a terminal of a specific user, and the broadcast service is to a group set to an arbitrary standard (region, subscription information, etc.). As a service for sending a short message (SMS) to the terminals of the users to which it belongs, retransmission is impossible and it is unknown whether each terminal is received.

That is, the conventional broadcast message service method unilaterally transmits a broadcast message to all users belonging to a group set by an arbitrary criterion, and a user who has the authority to receive such a broadcast message receives all broadcasts on the broadcast channel selected by the user. You will receive a message.

In the above-described broadcast message service method, not only whether the terminal has properly received the broadcast message, but also if the user cannot receive the broadcast message due to a special situation because it is impossible to retransmit the broadcast message, the special situation is terminated. There is a problem in not receiving a broadcast message.

The present invention has been made to solve the above problems, and when the user does not receive the broadcast message due to a special situation of the user, by retransmitting the broadcast message in the broadcast message center according to the user's request for retransmission of the broadcast message, the user can receive news or useful It is an object of the present invention to provide a broadcast message service method in which information is not missed.

According to an aspect of the present invention, when a terminal moves from a region where a broadcast message cannot be received to a receiveable region, a user equipment transmits a broadcast service retransmission request signal for an unreceived broadcast service from the terminal to a broadcast message center. The broadcast service retransmission request signal may include broadcast service information designated by a user among the unreceived broadcast services. And receiving, at the broadcast message center, the broadcast service retransmission request signal and transmitting a broadcast message according to the broadcast service information designated by the user to the terminal.

Hereinafter, operations and effects of the broadcast message service method according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating an operation of a broadcast message service method according to the present invention. As shown in FIG. 1, when a user moves from a region where a broadcast message cannot be received to a receiveable region, the user requests a broadcast service retransmission request signal to a broadcast message center. Transmitting (SP1, SP2); In the broadcast message center, a process (SP3, SP4) of transmitting a broadcast message according to a broadcast service retransmission request signal transmitted by a user to a corresponding terminal.

Such operation of the present invention will be described.

First, when managing a broadcast message, the broadcast message center manages the message with a sequential message ID for each channel, and the transmitted broadcast message is stored in the broadcast message center for a predetermined period.

In the broadcast message center, when a broadcast message is transmitted to all users, a user in a receivable area receives the broadcast message as a short message (SMS) to obtain arbitrary information.

If a user is located in an area where a broadcast message is not received, the user may not receive a broadcast message transmitted from the broadcast message center.

In this state, when the user moves from the broadcast message reception area to the broadcast message reception area, the user may receive a broadcast service retransmission request signal for retransmitting a broadcast message not received by the broadcast message center. After the creation (SP1), the broadcast service retransmission request signal is transmitted (SP2).

Here, the broadcast service retransmission request signal is composed of a short message (SMS). As shown in FIG. 2, the short message (SMS) includes a region of the message (UDL: length of the message) and user data. Length of User Data Header (UDHL), the area where the ID of the broadcast message is stored (IEI: Information Element Identifier), and the area where the size of the broadcast message is stored (IEIDL: Length of IED) and. A user data area (UD: User data) in which a broadcast message requesting retransmission is stored.

The user data area (UD: Userdata) storing the broadcast message requested to be retransmitted is stored in the channel ID of the broadcast message requesting retransmission as shown in FIG. 3 and the ID of the first broadcast message requesting retransmission. And an area in which the ID of the last broadcast message to request retransmission is stored. By using this, the first broadcast message and the last broadcast message can be designated among the sequential broadcast messages that the user has not received, so that the user can designate and receive the broadcast message to be re-received among the unreceived broadcast messages.

Next, the broadcast message center selects the corresponding broadcast message with reference to the broadcast service retransmission request signal transmitted by the user (SP3), and then transmits the selected broadcast message to the corresponding terminal (SP4), that is, the broadcast message. The center creates a short message (SMS) in the form of a short message (SMS) among the previously sent broadcast messages by referring to the broadcast message retransmission request signal and transmits the message to the user's terminal.

In other words, according to the present invention, a user transmits a retransmission request signal of a broadcast message defined in a predetermined format to a broadcast message center, so that the broadcast cannot be received due to being in an area where broadcast message service is unavailable or the terminal is turned off. By receiving and receiving the message again, the user's convenience is improved.

The specific embodiments or examples made in the detailed description of the present invention are intended to clarify the technical contents of the present invention to the extent that they should not be construed as limited to these specific embodiments and should not be construed in consultation. Various changes can be made within the scope of.

As described in detail above, the present invention retransmits a broadcast message at a broadcast message center in response to a request for retransmission of the broadcast message when the broadcast message is not received due to a special situation of the user, so that the user does not miss news or useful information. There is an effect of improving the convenience of the user.
