The present invention relates to a method and to a wireless personal area network (WPAN) device in which the device sets the beacon slot in the WPAN device and receives beacon slot information from neighbor devices, while setting the beacon table of the devices, to avoid the transmission time of the neighbor devices and the transmission time of the devices neighboring the neighbor devices in a WPAN. In the method, beacon message, including information about neighbors' transmission time and information about neighbors' neighbors' transmission time, is received from neighbor devices. The beacon message is combined, and the neighbors' transmission time information and the neighbors' neighbors' transmission time information are input into a beacon table. The neighbors' transmission time and the neighbors' neighbors' transmission time are input into a field for BTTSs to be avoided in the beacon table. The first beacon slot is set, as my beacon transmission slot, among beacon slots except for the transmission time input into the field for BTTSs to be avoided. Information about the set beacon transmission slot is input into a field for my BTTS in the beacon table.

The present invention relates to a system and to a method for QoS (Quality of Service) support in a ubiquitous sensor network. The system for QoS support in a ubiquitous sensor network includes a mesh coordinator and nodes. The mesh coordinator organizes a super frame containing a dedicated QoS data transmission period, and synchronizes each of the nodes constituted into one network with the abovementioned super frame. The nodes create a beacon frame containing information on whether or not to set QoS, to broadcast the beacon frame in a dedicated beacon period of the super frame if QoS data transmission is needed, to create a QoS data frame with a set priority, and to transmit the QoS data frame to the dedicated QoS data transmission period of the super frame in the case of transmitting QoS data. The present invention divides QoS data from general data to improve the quality of data transmission and ensure stability, and prioritizes QoS data to transmit the most important data among QoS data in a quick and stable manner.

The present invention relates to a method of efficiently assigning addresses in a WPAN and a WPAN device. The address assignment method of the present invention is performed by a higher device. Address assignment information for determining an address to be assigned to a lower device, is managed. An address is assigned to a lower device that requests connection from the higher device based on the address assignment information. The address assignment information is updated to a address value as the address value is assigned, and the updated address assignment information is transmitted to lower devices. If an update of address assignment information is requested by the lower device that assigned an address value to a device lower thereto, the address assignment information is updated and the updated address assignment information is transmitted to lower devices.

Provided is a power allocation method and apparatus for providing a packet data service in a mobile communication system is capable of reducing outage of a line service while simultaneously providing the line service and the packet service. It is checked whether or not packet data traffic to be transmitted to a specified mobile station is newly generated. If the packet data traffic is newly generated, it is checked whether or not there is the mobile station making use of the line service where a current call is in progress. If there is the mobile station making use of the line service where the current call is in progress, it is checked whether or not the packet data traffic is currently transmitted to any other mobile station. If the packet data traffic is not currently transmitted to the other mobile station, the power transmitted to the mobile station making use of a new packet data service is gradually increased by a preset increment for a preset predetermined time. Thereby, it is possible to innovatively reduce the outage of the mobile station making use of the line service while simultaneously providing the line service and the packet service as compared with the prior art.
