Initiate a channel switch of the entire cell to a new operating channel within (Tch_move - 0.5) seconds from the time when database informed the SM. The new operating channel should be the highest priority backup channel. The default value of the Tch_move shall be 2 seconds. 1b CPE DB If the SM is directed by the database service that the current operating channel is no longer available for some of the CPEs. Option 1: Initiate a channel switch of the entire cell to a new operating channel within (Tch_move - 0.5) seconds from the time when database informed the SM. The new operating channel should be the highest priority backup channel. The default value of the Tch_move shall be 2 seconds. Option 2: Dis-associate the CPEs that are not allowed to operate on the current channel within (Tch_move - 0.5) seconds from the time when the database informed the SM and continue normal operation with the other CPEs. A DREG-CMD (Section 6.10.16) in order to drop their association on the current operating channel shall be sent to these CPEs so that they no longer wait for an allocation in the US-MAP and/or transmit an opportunistic BW request UCS or Ranging request. Further, the BS may signal the affected CPEs to move to a particular channel using a DREG-CMD, in order to re-associate themselves with another BS and continue their operation. The default value of the Tch_move shall be
