Abstract

A method and a system for controlling an upper limit rate system subscriber's packet call are provided to enable a user, who is affiliated with a fixed rate multimedia message service, to transmit multimedia messages, regardless of the exhaustion of his maximum amount, by judging whether the subscriber is affiliated with the fixed rate multimedia message service in case the subscriber's maximum amount has been used up and transmitting a multimedia message to a receiving terminal in case the subscriber is affiliated with the fixed rate multimedia message service. A system for controlling an upper limit rate system subscriber's packet call comprises an SCP(Serving Control Point)/SDP(Serving Data Point)(130) and an MMS center(140). The SCP/SDP stores necessary programs for intelligent service control and subscriber information, and transmits associated subscriber information if a subscriber information request signal is received. The MMS center receives a multimedia message request signal from an originating terminal(110), transmits the subscriber information request signal to the SCP/SDP, and receives subscriber information from the SCP/SDP. Based on the received subscriber information, the MMS center judges whether the subscriber's maximum amount has been used up. If so, the MMS center judges whether the subscriber is affiliated with a fixed rate multimedia message service. If so, the MMS center transmits a multimedia message to a receiving terminal(112).

The present invention relates to a method and a system for controlling a packet call of an upper limit subscriber. More specifically, the MMS center receives the multimedia message request signal from the calling terminal, transmits the subscriber information request signal to the SCP / SDP for each service, and the upper limit amount of the subscriber is exhausted according to the subscriber information received from the SCP / SDP. The present invention relates to a method and system for controlling a packet call of an upper-rate subscriber who determines whether or not a subscriber subscribes to a multimedia message subscription service and transmits a multimedia message to a called terminal.

Mobile communication service is divided into voice call service and data service. In general, the voice call service is for a telephone call, and the data service includes wireless Internet, Fax, E-mail transmission, and various database searches.

In such a mobile communication service, there is an upper limit plan in which the user charges as much as the user uses the voice call service and the data service, or the user presets the use amount and uses the voice call service and the data service for the set amount.

When the user selects the upper limit plan, when the usage fee of one of the voice call service and the data service exceeds the upper limit rate, the upper limit rate service is limited. For example, if the usage fee for the data service exceeds the upper limit, voice call is possible but data service is not possible. In other words, if the user attempts to connect to the data service for which the upper limit fee is exceeded, the connection is not established and the user's terminal displays the same message as when the connection is not made due to a system failure.

In addition, a flat rate plan is provided that allows a subscriber to use a mobile communication service without paying only a predetermined amount, and the flat rate system has an advantage of removing a burden on a mobile communication service fee by paying only a predetermined amount.

Recently, a multimedia messaging service (MMS) for transmitting a short message including music, pictures, and videos is provided. The multimedia messaging service does not perform packet charging as packet data, and general short message. As with services, per-count charges are applied to deduct per-capital charges from the upper limit.

However, when a user applies for a flat rate plan for a multimedia messaging service, if the user's upper limit is exhausted due to a per-charge plan such as a general short message service, there may be a problem in that the service cannot be provided even though the flat rate plan is used.

In order to solve the above-described problem, the present invention, MMS center receives a multimedia message request signal from the originating terminal, transmits the subscriber information request signal to the SCP / SDP for each service, according to the subscriber information received from the SCP / SDP Provides a method and system for controlling a packet call of a subscriber of a maximum rate plan that transmits a multimedia message to a called terminal when it is determined that the subscriber is subscribed to the multimedia message subscription service when the maximum amount of money is exhausted. Its purpose is to.

Accordingly, according to a first object of the present invention, there is provided a calling terminal for transmitting a multimedia message request signal, a called terminal for receiving the multimedia message, a voice call service and a wireless data service, and a connection for transmitting and receiving the multimedia message.

It is determined whether or not subscribed to the multimedia message subscription service and if the multimedia message subscription service is determined to include a multimedia messaging service (MMS) center for transmitting the multimedia message to the called terminal through the mobile communication network; Provided is a packet call control system for an upper limit subscriber.

According to a second object of the present invention, there is provided a calling terminal for transmitting a multimedia message request signal, a receiving terminal for receiving the multimedia message, a voice call service and a wireless data service, and providing a connection path for transmitting and receiving the multimedia message. Service control system (SCP: Service Control Point, hereinafter referred to as 'SCP') / Service Data System (SDP: Service Data Point, hereinafter referred to as 'SDP') A method of controlling a packet call of a subscriber of a maximum rate plan in a mobile communication system, comprising: (a) receiving the multimedia message request signal from the calling terminal; (b) transmitting a subscriber information request signal to the SCP / SDP for each service; (c) receiving subscriber information from the SCP / SDP; (d) determining whether the upper limit amount of the subscriber is exhausted according to the subscriber information; (e) determining whether the subscriber is subscribed to the multimedia message subscription service when the subscriber determines that the upper limit is exhausted in step (d); And (f) transmitting the multimedia message to the called terminal through the mobile communication network when it is determined in step (e) that the multimedia message subscription service is subscribed to. Provide a control method.
