Abstract: A wireless device receives a request to originate a data call, e.g., from the user or a higher layer application. If origination control is not to be applied, then the wireless device originates the data call immediately. Otherwise, the origination of the data call is controlled based on prior data call origination attempts that are applicable to the data call. For example, the wireless device may originate the data call immediately if (1) the most recent origination attempt was successful or (2) the most recent origination attempt was unsuccessful but a predetermined time period has elapsed since this unsuccessful origination attempt. If the most recent origination attempt was unsuccessful and the predetermined time period has not elapsed, then the wireless device may (1) wait until this predetermined time period elapses and then originate the data call or (2) reject the data call.

Abstract: A radio receiver has a low noise amplifier. The low noise amplifier is enabled. If a predicted level of interference is expected to produce an acceptable bit error rate or other signal error measurement, the low noise amplifier is set to a "low" linearity level. If the predicted level of interference is not expected to be acceptable, the low noise amplifier is adjusted to a "high" level of linearity. The level of linearity required is determined by checking one or more prediction criteria: the mobile station's current operating mode, the strength of a received signal, the strength of a signal transmitted by the mobile station, the current level of interference, an acceptable level of interference, and whether the low noise amplifier is enabled or bypassed. Each of the prediction criteria may not be weighted equally. The determination is repeated as the prediction criteria change.

Abstract: An in-bound call directed telephone station, and a method, which may be embodied in a computer readable medium, directs a telephone station based on an in-bound call. The inbound directed telephone station includes means for providing a handset having a call receiver and a call originator, means for providing a first memory location, coupled to the call receiver, and means for providing a comparator coupled to the first memory location and to the call receiver. Upon receipt of an inbound call by the call receiver and before the call receiver answers the in-bound call, the comparator compares an identifier of the in-bound call to an identifier list in the first memory location and terminates receipt of the in-bound call by the call receiver. Upon locating a match between the identifier list and the identifier of the in-bound call, the comparator automatically activates the call originator to perform a function associated with the in-bound call identifier. The method includes receiving a call at the telephone, activating an identification system based on the receiving, which identification system identifies an origination of an in-bound communication, associating a function with the in-bound communication based on the origination, terminating the in-bound communication after the activating of the identification system and before answering the in-bound call, and automatically performing, by the telephone, of the function associated with the in-bound communication.
