Abstract
When determination is made that a channel for high-speed downlink packet transmission is short in power by the calculation of power assigned to a downlink shared channel and an activity ratio of the power assigned to the downlink shared channel from transmission power of all the channels and transmission power of other channel than a downlink shared channel for high-speed downlink packet transmission, a total sum of transmission power of dedicated channels is reduced by lowering a rate of a connected dedicated channel for data reception, thereby increasing power assigned to the channel for high-speed downlink packet transmission.
Claims17
A radio network controlling method comprising the steps of:
- transmitting data to a mobile station by using a downlink dedicated channel and a downlink shared channel,
- measuring transmission power of all the channels and transmission power of other channel than said downlink shared channel,
- calculating power assigned to said downlink shared channel from the transmission power of other channel than said downlink shared channel,
- calculating an activity ratio of said assigned power from the transmission power of said all the channels, the transmission power of other channel than said downlink shared channel and said assigned power, and
- regulating use of said downlink dedicated channel according to said assigned power and said activity ratio.
