摘要： Feature access control is provided for soft-labeled keys (SLKs) of a wireless terminal or other type of terminal in a communication system. In an illustrative embodiment, a different set of SLK label identifiers are associated in a control table with each state in a set of states of the terminal. Each of the label identifiers specifies a label to be associated with a given one of the SLKs in a given one of the states. The label identifiers are used as pointers into a label table which specifies, for each of the label identifiers, a corresponding label for one of the SLKs. The control table and label table together implement a bidirectional mapping between single switch-based features and corresponding multiple state-based appearances of those features on the terminal. The control table and label table may be downloaded into the terminal from a switch of the system. The SLK labels of the terminal may be updated by, e.g., transmitting to the terminal a state identifier, an identifier of a most-recently activated feature, and a presentation attribute for that feature.
