INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract Disclosed is a technique for starting an application used to receive a message for the application efficiently in order to reduce the processing load on and the battery consumption of a user terminal. According to this technique, a network is requested to transmit a control message to a user terminal when receiving a message addressed to an application on the user terminal, and when receiving, from a server, a message addressed to the application on the user terminal, the network transmits a control message such as paging to the user terminal. The user terminal receives the paging from the network even in the connected mode, and starts an application used to receive a message for the application on the user terminal in response to the reception of the paging so that the application can be started at timing where there exists the message to be received. ## Claims ### Claim 1 A communication system comprising: a user terminal, a network device including a network entity that is an element of a network, and a predetermined communication device as a communication partner of the user terminal, wherein the predetermined communication device includes a message transmission unit for transmitting, to the network, a request message including application identification information for identifying an application on the user terminal, the request message requesting the network device to transmit a control message to the user terminal, the network device includes a control message transmitting unit for transmitting a control message including the application identification information to the user terminal when receiving the request message from the predetermined communication device as the communication partner of the user terminal, the control message being generated based on the request message, and the user terminal includes a control message receiving unit for receiving the control message from the network, and an application starting unit for starting an application identified by the application identification information when the control message is received at the control message receiving unit. ### Claim 2 A user terminal for performing communication with a predetermined communication device through a network, comprising: a control message receiving unit for receiving, from the network, a control message including application identification information for identifying an application on the user terminal, the control message being generated based on a request message, and the request message being transmitted from the predetermined communication device and including the application identification information; and an application starting unit for starting an application identified by the application identification information when the control message is received at the control message receiving unit. ### Claim 3 (depends on 2) The user terminal according to claim 2, further comprising a response message transmitting unit for transmitting a response message indicative of the start of the application to the network when the application starting unit starts the application. ### Claim 4 (depends on 2) The user terminal according to claim 2, further comprising a control message transmission requesting unit for transmitting, to the predetermined communication device, a control message transmission request for requesting the predetermined communication device to transmit the request message to the network. ### Claim 5 (depends on 4) The user terminal according to claim 4, wherein the control message transmission requesting unit transmits the control message transmission request to the predetermined communication device when quitting a specific application on the user terminal. ### Claim 6 (depends on 4) The user terminal according to claim 4, further comprising an identification information adding unit for adding, to the control message transmission request, identification information for identifying an application on the user terminal. ### Claim 7 (depends on 2) The user terminal according to claim 2, wherein the user terminal uses SMS as the control message. ### Claim 8 A communication device for performing communication with a user terminal through a network, comprising a message transmission unit for transmitting, to the network, a request message including application identification information for identifying an application on the user terminal, the request message requesting a network device including a network entity that is an element of the network to transmit a control message to the user terminal. ### Claim 9 (depends on 8) The communication device according to claim 8, further comprising a message forwarding unit for forwarding, to the user terminal, a data packet related to an application when receiving, from the user terminal, a response message indicating that the application has been started on the user terminal based on reception of the control message. ### Claim 10 (depends on 8) The communication device according to claim 8, further comprising a control message transmission request holding unit for holding a control message transmission request when receiving, from the user terminal, the control message transmission request for requesting transmission of the request message to the network, wherein, upon starting communication with the user terminal, the message transmission unit transmits the request message to the network in case that the control message transmission request is held in the control message transmission request holding unit. ### Claim 11 (depends on 8) The communication device according to claim 8, wherein the message transmission unit transmits the request message to the network device based on the control message transmission request received from the user terminal. ### Claim 12 (depends on 8) The communication device according to claim 8, wherein the communication device requests the use of SMS as the control message.
