1. A radio base station comprising:
- a first baseband processor configured to perform a processing of a baseband signal including user data transmitted and received by a mobile station;
a second baseband processor used as a standby system of the first baseband processor;
a switching determiner configured to determine whether or not to switch from the first baseband processor to the second baseband processor;
an information transmitter configured to transmit a suspension request to suspend the transmission of the user data when the switching determiner determines the switching from the first baseband processor to the second baseband processor; and
an handover execution unit configured to perform the handover of a processing from the first baseband processor to the second baseband processor, based on the transmission of the suspension request by the information transmitter, or on the determination of the transmission of the suspension request, whereinthe information transmitter transmits the suspension request to set the transmission rate of the user data to zero.

Abstract
The radio base station includes a monitoring controller for determining whether to switch between BB cards; and a baseband signal processor for transmitting a suspension request to suspend the transmission of the user data when it is determined that the BB cards are switched, and performing the handover of a processing between the BB cards based on the transmission of the suspension request. The baseband signal processor transmits a capacity allocation or a zero grant requesting to set the transmission rate of the user data to zero.

9. A radio communication control method which uses a radio base station having a first baseband processor performing a processing of a baseband signal including user data transmitted and received by a mobile station, and a second baseband processor used as a standby system of the first baseband processor, the radio communication control method comprising the steps of:
-
determining whether or not to switch from the first baseband processor to the second baseband processor; transmitting a suspension request to suspend the transmission of the user data when the switching determiner determines the switching from the first baseband processor to the second baseband processor; and performing the handover of a processing from the first baseband processor to the second baseband processor, based on the transmission of the suspension request by the information transmitter, or on the determination of the transmission of the suspension request, wherein the suspension request to set the transmission rate of the user data to zero is transmitted in the transmitting step.
