Abstract
Variances in bandwidth used by a radiocommunication connection are adapted to by changing the type of information being transmitted. For example in a TDMA environment a first downlink time slot associated with a double-or triple-rate connection may have a first format while a second time slot associated with the same connection may have a second format different from the first format. Bandwidth in the second (or third) time slot can be used to carry information in a fast out-of-band channel (FOC). The FOC may provide information relating to the same connection as the payload or data field in that time slot e.g. a service type identifier which informs the mobile or base station of the type of information (e.g. voice video or data) being conveyed in the payload. Alternatively the FOC information may be associated with a connection or connections which are different from that supported by the payload or data field containing the FOC.
