Title:
無線通信ユニット及びそれを用いた無線ネットワークシステム
Document Type and Number:
Japanese Patent JP7461749
Kind Code:
B2
Abstract:
To provide a wireless communication unit that can smoothly transmit and receive important information such as emergency information even when communication traffic between the wireless communication unit and a specific wireless communication unit is congested.SOLUTION: There is provided, in an EPC functional part, an inter-unit bandwidth controller which adjusts and controls a communication bandwidth of each inter-downstream unit wireless bearer for the connection of relay wireless communication parts of downstream units to a wireless base station part such that the more the number of relay wireless communication parts, the narrower the communication bandwidth, depending on the number of the relay wireless communication parts of the downstream units connected simultaneously to the wireless base station part. Thus, when a plurality of the downstream units is connected and a communication load of a specific wireless communication unit increases, communication traffic can be allowed to have a margin in consideration of the transmission and reception of emergency information etc. by reducing a set bandwidth of an inter-unit wireless bearer between the downstream units and the specific wireless communication unit.SELECTED DRAWING: Figure 1
