Abstract
The software and hardware within a base station controller and within a mobile station are modified to redefine a flag which is used for controlling communications there between. Additionally, a new flag is created. The system with the modified flag and the new flag allow a channel which is carrying communication control information to be temporarily interrupted so that a data burst may be transmitted on the same channel. In general, the base station controller transmits to the mobile station a plurality of signals which include specified counter values and information relating to a plurality of flags. The preferred embodiment includes six flags and three counters. The flags include the Not Received flag, Received flag, Busy flag, Reserved flag, Idle flag, and Check flag. It is the functionality of the Idle flag which has been redefined. The Check flag is new. The methods for determining when to transmit a data burst are responsive to multiple combinations of the flags. In the preferred embodiment, only one of the Busy, Reserved, Idle and Check flags is transmitted and one of the Received/Not Received flags is transmitted. Additionally, the Partial Echo value is transmitted which identifies the last mobile station from which the base station acknowledged a data burst.
