System and method for confirming short message service (SMS) message reception in mobile communication terminal

A method for confirming a Short Message Service (SMS) message reception in a first mobile communication terminal adapted to transmit a SMS message to a second mobile communication terminal, comprising the steps of:

• detecting an SMS message to be transmitted at the first mobile communication terminal, transmitting the SMS message to a base station, and determining whether the SMS message is received at the base station;
• enabling the first mobile communication terminal to enter a standby mode for a prescribed duration of time in order to receive a confirmation signal from the base station, and receiving information generated from the base station at the first mobile communication terminal, if it is determined that the SMS message is received at the base station;
• determining whether a signal indicating that the second mobile communication terminal is powered off has been received, and if so, displaying a powered-off indication on the first mobile communication terminal signal indicating the powered-off state of a second mobile communication terminal;
• determining whether an acknowledgement signal indicating that the second mobile communication terminal has received the SMS has been received, and if so, displaying an SMS reception confirmation indication on the first mobile communication terminal to indicate the SMS message reception;
• and
• displaying a service failure state on the first mobile communication terminal in the absence of a signal confirming the SMS message reception information and the signal indicating the powered-off state of the second mobile communication terminal is received at the first mobile communication terminal.

A method for confirming a Short Message Service (SMS) message reception in a base station for a SMS message transmitted from a first mobile communication terminal to a second mobile communication terminal, comprising the steps of:

• transmitting a SMS reception confirmation signal to the first mobile communication terminal if the base station receives the SMS message from the first mobile communication terminal;
• transmitting the SMS message to the second mobile communication terminal;
• enabling the base station to determine whether the second mobile communication terminal is powered off, transmitting a signal indicating a powered-off state to the first mobile communication terminal if the second mobile communication terminal is powered off;
• enabling the base station to transmit a response signal to the first mobile communication terminal if the base station receives response information indicating that the SMS message is received at the second mobile communication terminal;
• and
• displaying on said first mobile communication terminal a status indication of whether (a) said second mobile communication terminal received said SMS message, (b) said second mobile communication terminal is powered off, and (c) service failure information.

A system for confirming a Short Message Service (SMS) message reception between terminals in a mobile communication network, the system comprising:

• a first mobile communication terminal, a second mobile communication terminal, and a base station;
• said first mobile communication terminal being adapted to send the SMS message to said base station;
• said base station being adapted to send a first reception acknowledgement signal to said first mobile communication terminal, and to send the SMS message to said second mobile communication terminal;
• said second mobile communication terminal being adapted to send a second reception acknowledgement signal to said base station;
• and
• said base station being further adapted to receive said second reception acknowledgement signal, and to transmit a response signal to said first mobile communication terminal indicative of whether the SMS message is received at said second mobile communication terminal;
• and
• said first mobile communication terminal being further adapted to display signals indicative of (a) a power off condition of said second mobile communication terminal;
• (b) receipt of the SMS message at said second mobile communication terminal;
• and (c) service failure.

• a first mobile communication terminal, a second mobile communication terminal, and a base station;
• said first mobile communication terminal being adapted to detect an SMS message to be transmitted, transmit the SMS message to said base station, and determine whether the transmitted SMS message is received at said base station;
• said first mobile communication terminal being further adapted to enter a standby mode for a prescribed duration of time in order to receive a confirmation signal from the base station, and to receive information generated from the base station, if it is determined that the SMS message is received at the base station;
• and
• said first mobile communication terminal being further adapted to display (a) a powered-off state if the information received from the base station is a signal that indicates the powered-off state of said second mobile communication terminal;
• (b) a SMS reception confirmation signal if the information received from the base station is a signal confirming a SMS message reception, and (c) a service failure state in the absence of a signal confirming the SMS message reception information and the signal that indicates the powered-off state of the second mobile communication terminal is received at the first mobile communication terminal.

A system for confirming a Short Message Service (SMS) message reception between terminals in a mobile communication network, the system comprising:

• a first mobile communication terminal, a second mobile communication terminal, and a base station;
• said base station being adapted to transmit a SMS reception confirmation signal to said first mobile communication terminal if said base station receives the SMS message from said first mobile communication terminal and transmit the SMS message to the second mobile communication terminal;
• and
• said base station being further adapted to determine whether said second mobile communication terminal is powered off, transmit a signal to indicate a powered-off state to said first mobile communication terminal if said second mobile communication terminal is powered off, and transmit a response signal to said first mobile communication terminal,
• wherein said first mobile communication terminal is further adapted to display a status indication (a) that said second mobile communication terminal received said SMS message when said SMS reception confirmation signal is received, (b) that said second mobile communication terminal is powered off when the signal to indicate a powered-off state is received, and (c) that service has failed when neither the SMS reception confirmation signal nor the signal to indicate a powered-off state has been received.

A system for confirming a Short Message Service (SMS) message reception between terminals in a mobile communication network, the system comprising:

• a first mobile communication terminal, a second mobile communication terminal, and a base station;
• said base station being adapted to determine whether the second mobile communication terminal receives the SMS message transmitted from said base station;
• and
• said second mobile communication terminal being adapted to generate a SMS reception confirmation signal and transmit the SMS reception confirmation signal to said base station if said second mobile communication terminal receives the SMS message from said base station,
• wherein said first mobile communication terminal is adapted to display a status indication indicative of whether said second mobile communication terminal has received the SMS message, entered a power off state, or entered a battery removal state.
