Abstract
A method and apparatus for reducing degradation in the sensitivity of a receiver in a mobile phone are disclosed. The sensitivity of the receiver in the mobile phone is monitored. When the sensitivity degrades below a predetermined threshold, it is determined which feature of the mobile phone is causing the detected degradation. The operation of the feature is changed to reduce the amount of degradation produced by the feature.
Claims21
A method for reducing degradation in the sensitivity of a receiver in a mobile phone, comprising the steps of:
- monitoring the sensitivity of the receiver;
- detecting when the sensitivity degrades below a predetermined threshold;
- determining which feature of the mobile phone is causing the detected degradation;
- changing the operation of the feature to reduce the amount of degradation produced by the feature;
- and
- wherein the step of determining which feature is causing the detected degradation comprises the steps of:
- determining what frequency the receiver is using;
- selecting a stored list of probable features causing the interference for the determined frequency;
- momentarily changing the operation of each active feature on the stored list to determine if the degradation is improved to an acceptable level when the operation is changed.
An apparatus for reducing degradation in the sensitivity of a receiver in a mobile phone, comprising:
- a monitor for monitoring the sensitivity of the receiver;
- a detector for detecting when the sensitivity degrades below a predetermined threshold;
- a processor for detecting which feature of the mobile phone is causing the detected degradation, wherein said processor changes the operation of the feature to reduce the amount of degradation produced by the feature;
- and
- wherein the processor detects which feature is causing the degradation by:
- determining what frequency the receiver is using;
- selecting a stored list of probable features causing the interference for the determined frequency;
- momentarily changing the operation of each active feature on the stored list to determine if the degradation is improved to an acceptable level when the operation is changed.
A computer readable medium storing code for reducing degradation in the sensitivity of a receiver in a mobile phone, said code comprising:
- code for monitoring the sensitivity of the receiver;
- code for detecting when the sensitivity degrades below a predetermined threshold;
- code for determining which feature of the mobile phone is causing the detected degradation;
- code for changing the operation of the feature to reduce the amount of degradation produced by the feature;
- and
- wherein the code for determining which feature of the mobile phone is causing the detected degradation comprises:
- code for determining what frequency the receiver is using;
- code for selecting a stored list of probable features causing the interference for the determined frequency;
- code momentarily changing the operation of each active feature on the stored list to determine if the degradation is improved to an acceptable level when the operation is changed.
