Abstract: There are provided a method for providing a relay network and a mobile router and a network relay system using the same. The method for providing the relay network is performed in the mobile router generating the relay network using a plurality of mobile terminals. The method for providing the relay network includes checking a remaining data usage amount for the plurality of respective mobile terminals using a first wireless communications network, checking a tethering priority using the remaining data usage amount and determining a first mobile terminal having the highest tethering priority, and configuring the relay network by providing wireless data provided from the remainder of mobile terminals to the first mobile terminal through a second wireless communications network.

Abstract: An Electronic Information Label (EIL), a server, and a method of transmitting a call signal are provided. According to an exemplary embodiment, an EIL includes: a receiver configured to receive manipulation from a user; a detector configured to cause an interrupt signal by detecting the manipulation received in the receiver; and a call request transmitter configured to wake up in response to detection of the interrupt signal, and transmit a call request signal to a management server to request a call for a person in charge.

Abstract: There are provided a machine-to-machine (M2M) server and a data processing method thereof. The M2M server includes: a receiving unit receiving a plurality of pieces of sensor data from a plurality of M2M devices; a combining unit combining the plurality of pieces of sensor data transferred from a receiving unit with each other according to a preset profile; and a transmitting unit transmitting the combined pieces of sensor data.
