Abstract: A wireless terminal or other type of terminal in a communication system is controlled in a bandwidth-efficient manner using commands associated with a terminal protocol supported by a switch of the system. In an illustrative embodiment, a set of command symbols are generated by: (i) resizing a command space associated with a wired terminal protocol to obtain a reduced command space suitable for use with a wireless terminal; (ii) generating a representation in which a first portion of the reduced command space is correlated with a second portion of the reduced command space; and (iii) assigning command symbols to valid entries in the representation, such that a given one of the command symbols uniquely identifies a particular combination of commands in the reduced command space. The switch transmits a given command symbol to the wireless terminal, and the wireless terminal decodes the symbol and executes the corresponding commands specified by the symbol.

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.
