Abstract
Soft-labeled keys (SLKs) of a wireless terminal or other type of terminal in a communication system are controlled in an efficient manner using a state-based control model. In an illustrative embodiment, a state machine is generated such that each state in the state machine specifies a set of labels for a corresponding set of soft-labeled keys associated with the wireless terminal. At least a portion of the state machine is downloaded from a switch of the system, and processed to generate a display including a given one of the sets of labels. The state machine may be in the form of a state transition table which includes, for each state, (i) a set of labels for the set of soft-labeled keys, (ii) a set of feature identifiers, e.g., system codes, each identifying, for a given one of the labels, a particular feature supported by the switch, and (iii) a next state which is entered when the corresponding soft-labeled key is selected by the user. After a given one of the soft-labeled keys is selected by a user, the corresponding feature identifier is transmitted from the wireless terminal to the switch. The state transition table may also support a local mode in which selecting a particu…
