Abstract:
A base station that communicates with a mobile station includes: a storing unit for storing a predetermined number of base station information, each including a base station ID for discriminating a specific base station and parameter information for radio communications set for the specific base station; an acquisition unit for acquiring a base station ID of other base stations forming a destination cell of the mobile station, or a base station ID of other base station forming a source cell of the mobile station; an aggregating unit for aggregating the number of times that each of the base station IDs is acquired in a first time period; a determination unit for determining a priority of each of the base station IDs on the basis of the aggregated results of the acquisition numbers; a judging unit for judging whether or not there is a base station ID which has a priority higher than the base station ID stored in the storage, and whose acquisition number is larger than a predetermined number of times; and a manager for deleting, from the storage, a base station information including a base station ID having a priority lower than the base station ID judged to have a higher priority, and for storing, in the storage, a base station information including the base station ID judged as to have the higher priority, in a case where the judging unit judges there is the base station ID having a higher priority and whose acquisition number is larger.
Abstract:
Disclosed is a radio base station including: a common control channel transmission unit configured to transmit a common control channel by using radio communications parameter to be assigned to each radio base station; a transmission level determination unit configured to transmit the common control channel according to a predetermined transmission pattern; a reception level supervision unit configured to acquire a reception level of the common control channel received by a mobile station; and an overlap determination unit configured to determine whether or not the predetermined radio communications parameter overlaps with a radio communications parameter used in a different radio base station based on the reception level acquired by the reception level supervision unit and the predetermined transmission pattern.
Abstract:
To automatically set up temporarily the parameters required for radio communication, based on the parameters acquired from another base station apparatus existing in the neighborhood. A pair of base station identifier and down scrambling code reported from a base station apparatus in the neighborhood is acquired. The non-overlapping down scrambling code is set to a newly established base station apparatus based on the acquired contents. Whether or not the base station apparatus is located in the neighborhood is judged according to at least one of the Hop number and the required arrival time on a communication path up to the base station apparatus.
Abstract:
To provide a base station apparatus that can automatically update the parameters required for radio communication. A pair of identifier for identifying the self station and radio communication parameter is notified to another base station existing in the neighborhood of the self station, and the path loss value between another base station and a mobile station and the pair of identifier and radio communication parameter for another base station is acquired. The pair of identifier and radio communication parameter reported by the self station is set and updated, based on this acquired information. Since it is updated in consideration of the path loss value reported from the mobile station, the parameter can be updated at higher precision.
Abstract:
A base station and method of communication of a base station is provided. The base station includes a storage configured to store a predetermined number of base station information, each including a base station ID, an acquisition unit configured to acquire base station IDs, an aggregating unit configured to aggregate a number of times that each of the base station IDs is acquired, and a determination unit configured to determine a priority of each of the base station IDs. The base station also includes a judging unit configured to judge whether or not there is a base station ID having a priority higher than the base station ID stored in the storage, and a manager configured to delete from the storage, and store in the storage, base station information including a base station ID.

Abstract:
A communication control device is provided which efficiently utilizes wireless resources to improve communication quality and system throughput by appropriately setting and performing node transmission power. The communication control device in a wireless LAN system includes a sender 206, a receiver 207, and an inter-AP communication function 211 for determining, based on at least one of wireless information obtained by measurement of a wireless signal by an access point 103 or a station 104a, or reported wireless information, whether or not there is a neighboring BSS, and a transmission power determination function 210 and a transmission power setting/update function 205 for setting and updating the transmission power of the access point 103 and the station 104a in its own BSS when there is a neighboring BSS in which all the access point have the control function of the transmission power, on the other hand, for maximizing the transmission power when there is no neighboring BSS or when there is a neighboring BSS that does not control the transmission power.
Abstract:
A wireless control apparatus is disclosed that forms and controls an area of a base station according to an antenna pattern. The wireless control apparatus includes an area formation information gathering part that gathers area formation information pertaining to area formation of a neighboring base station; and an antenna pattern control part that controls and directs at least one of a main lobe, a side lobe, and a null point between the main lobe and the side lobe of the antenna pattern based on the area formation information to reduce frequency interference between a current cell formed by a current base station and a neighboring cell formed by the neighboring base station.
