The present disclosure relates to a lighting device based on scenario-activation using a push service, and a push server, a control device and a communication device for controlling the lighting device. In one embodiment of the present disclosure, a push server for controlling a lighting device based on scenario-activation using a push service, may include: a communication unit for receiving a control message, based on a first communication protocol, from a control device and for transmitting the received control message to either a communication device or a push gateway based on the first communication protocol; a control message storage unit for storing, therein, the control message; a communication device-identification storage unit for storing, therein, identifications of communication devices to receive the control message; and, a control unit configured for controlling the communication unit, the control message storage unit, and the communication device-identification storage unit.

A multimedia mobile communication system for recovering a handoff failure comprises: a hybrid access terminal; a base station transceiver subsystem for transmitting and receiving the voice and the data; a base station a mobile switching center a 1&#xd7;EV-DO transceiver; and an access network controller for controlling the handoff by transmitting a traffic channel assignment signal when there is no response from the hybrid access terminal upon receiving the route update signal from the hybrid access terminal and transmitting the traffic channel assignment signal in response to the route update signal and a packet data serving node.

Method and system for recovering from hand-off fail for use in CDMA 2000 1xEV-DO system

A method and a system for controlling a reverse link rate by using the number of active users who are carrying out communication in a CDMA 1xEV-DO mobile communication system is disclosed. A value of rise-over-thermal (ROT) at each antenna end of a wireless base station is measured and compared with a threshold ROT which defines an allowable limit of the ROT. A reverse activation control bit is set as 0 if the measured ROT value is smaller than or equal to the threshold ROT. The number of the active users is compared with a threshold user number which defines an allowable limit of the active users if the measured ROT value is greater than the threshold ROT. The reverse activation control bit is set as 0 if the number of the active users is smaller than or equal to the threshold user number. The reverse activation control bit is set as 1 if the number of the active users is greater than the threshold user number.

A telecommunication system for appointing a frequency assignment mode and ratio for providing a broadcast/multicast service includes at least one access terminal (AT) for receiving a 1xEV-DO service or the BCMCS through a 1xEV-DO system, a base station manager (BSM) for receiving BCMCS control information containing the FA mode and/or the BCMCS assignment ratio and transmitting the received BCMCS control information to a 1xEV-DO access network controller (ANC), and an access network including a 1xEV-DO access network transceiver subsystem (ANTS) and the 1xEV-DO access network controller for temporarily storing the received BCMCS control information and controlling a sort and/or a ratio of a message, which is transmitted to each access terminal, according to the FA mode and/or the BCMCS assignment ratio contained in the BCMCS control information.

Method and telecommunication system for appointing frequency assignment mode and/or broadcast/multicast service assignment ration for providing broadcast/multicast service

The system in accordance with the present invention recognizes in real time that a call connection of a hybrid access terminal be switched over to a 1X system, by sending an inquiry message inquiring the hybrid access terminal of whether the hybrid access terminal has received voice signal or a low-rate data signal and by receiving a confirmation message that the hybrid access terminal has received the voice signal or the low-rate data signal from a mobile switching center, if a low-level signal below a prescribed level is received from the hybrid access terminal while counting time initiated from a point of a call drop while the hybrid access terminal is being provided with a multimedia service.

Method and system for recognizing call switch-over from 1xEV-DO system to 1X system

The present invention relates to a method and system for switching over a call connection of a hybrid access terminal to a 1X system if a 1XEV-DO system has a problem when the hybrid access terminal requests a call connection to the 1xEV-DO system. The system in accordance with the present invention includes the hybrid access terminal, a 1X transceiver subsystem, a 1X controller, a mobile switching center, an access network transceiver subsystem, an access network controller, a packet data serving node and an IP network.
