Provided are a base station, a mobile station, and a method for providing service continuity between Multimedia Broadcast and Multicast Service (MBMS) areas. A system information generation unit of the base station may generate a System Information Block (SIB) including broadcasting area information providing a broadcasting service to a neighboring cell of a serving cell where the mobile station is located. A communication unit may transmit the generated SIB to the mobile station.

Disclosed is a system for providing an Evolved Multimedia Broadcast/Multicast Service (EMBMS) chatting service for providing a multi-chatting service. The system comprises at least one of a User Equipment (UE) to request establishment of a chatting channel and to transmit and receive a communication message and contents so as to transmit and receive the communication message with a plurality of mobile subscribers participated in the chatting channel, an evolved Broadcast Multicast-Service Center (eBM-SC) to perform control of an EMBMS service so as to transmit the communication message to the at least one of the UE using the EMBMS service, and a service provider server to transmit, to the eBM-SC, user service information, first bearer service information, and contents for each of the chatting channels, so that the UE transmits and receives the communication message with the plurality of the mobile subscribers participated in the chatting channel.

A method and apparatus for multimedia broadcast and multicast service (MBMS) counting is provided. A user equipment (UE) may transmit selected service information to a multi-cell and multicast coordination entity (MCE) through a target evolved node base station (eNB), every time that a service requiring counting is received or cancelled and thus, the MCE may accurately manage a number of UEs that receive a service for each eNB. Also, the use may transmit selected service information to the MCE through the target eNB every time that the UE enters a new cell and thus, the MCE may accurately manage a number of UEs that receive a service for each eNB.

According to an Evolved Multimedia Broadcast Multicast Service (E-MBMS) service method of the present invention, an E-MBMS service is received from a first base station. If neighbor cell MBMS control information is modified in the first base station, MBMS paging information, including a factor informing that the neighbor cell MBMS control information has been modified, is received from the first base station. When an MBMS control information update cycle is reached, modified neighbor cell MBMS control information is received from the first base station and is stored. When a user equipment moves from the first base station to a second base station, a P-T-M radio bearer is reset based on the stored neighbor cell MBMS control information and receiving the E-MBMS service from the second base station. Accordingly, the consumption of battery power can be reduced, and an E-MBMS service being services is not interrupted although a user equipment moves.

Provided is a multimedia broadcast and multicast service controlling apparatus and method based on a user location. The multimedia broadcast and multicast service controlling apparatus may receive MCCH information, may periodically update a service list of a mobile terminal based on the received MCCH information, the service list listing services that are providable, may register a service in a pending list when the service is not included in the updated service list and is requested to be provided, and may provide the service registered in the pending list when the mobile terminal reaches a location where the mobile terminal may provide the service registered in the pending list.

Disclosed are a system and a method for receiving an MBMS broadcasting service. In the present invention, in a mobile communication/wireless communication system, an MBMS service is provided by synchronizing a unicast bearer with a multicast bearer through scheduling information mapping at the time of transmitting a broadcast/multicast service through a unicast. Further, the present invention presents even a method for improving quality of experience (QoE) of the service by providing the MBMS service through the multicast bearer and the unicast bearer simultaneously. According to the present invention, MBMS services of various service qualities can be provided depending on wireless quality of a terminal or the capability of the terminal at the time of providing the MBMS service.

Disclosed is a method for receiving MBMS services from a base station supporting multi-carriers, including: receiving first system information including information on all the carriers; receiving second system information including information on multi-carriers supported by the base station; receiving MBMS control information through an MBMS control channel; and receiving the MBMS services through an MBMS transmission channel based on the MBMS control information.
摘要:
Disclosed is an efficient scheduling apparatus and method for multi-cell transmission in evolved node bases (eNBs). An eNB scheduling for a multi-cell transmission service may allocate wireless resources based on a priority level, a minimum guaranteed bit rate, and a maximum bit rate. That is, a subframe may be efficiently used by minimizing the number of subframes allocated to a single session while satisfying a quality of service (QoS).

Disclosed are an apparatus and a method for controlling a room lamp of a vehicle. The present invention relates to collecting information associated with the vehicle and information associated with an ambient environment using a global positioning system (GPS) or a controller area network (CAN) and then controlling the room lamp using at least one of turn-off of the room lamp, change of an irradiation angle of the room lamp, and adjustment of illumination of the room lamp based on the collected information.

Provided are a route guidance system and method for emergency vehicle using telematics. The route guidance system includes an instruction station, a vehicle telematics and a traffic signal controller. The instruction station sends destination information to an emergency vehicle for dispatch due to an occurrence of an emergency circumstance. The vehicle telematics is attached to the emergency vehicle, and searches a plurality of travel routes on the basis of the destination information to provide the shortest travel route. The traffic signal controller controls a corresponding traffic signal on the travel route before the emergency vehicle approaches on the basis of travel information sent from the vehicle telematics.
