Mobile electronic device and method
A mobile electronic device and method is disclosed. The mobile electronic device includes a detection module, a first memory a second memory and a clock control module. The detection module is configured to detect a user input to make an emergency call. The first memory stores one or more first clock rates. The clock control module configured to perform select one of the one or more first clock rates as a selected first clock rate such that an odd-multiple of the one of the first clock rates is different from a carrier frequency of a positioning signal that is received from a global positioning system. The control module is further configured to perform set a clock rate of the second memory to the selected rate in response to a detection of the user input.
1. A mobile electronic device comprising:
a detector configured to detect a user input to make an emergency call;
a first memory storing one or more first clock rates;
a second memory; and
a clock control configured to select one of the one or more first clock rates as a selected first clock rate such that an odd-multiple of the selected first clock rate is different from a carrier frequency of a positioning signal that is received from a global positioning system, and to set a clock rate of the second memory to the selected first clock rate in response to a detection of the user input;
wherein the clock control maintains the selected first clock rate as the clock rate of the second memory until a predefined period of time elapses.
2. The mobile electronic device according to claim 1 , further comprising:
a main control, wherein
the first memory further stores one or more second clock rates; and
the clock control is further configured to select one of the one or more second clock rates as a selected second clock rate; and set a clock rate of the main control to the selected second clock rate.
3. A method for controlling a mobile electronic device, comprising: the method comprising:
storing one or more first clock rates in a first memory;
detecting a user input to make an emergency call;
selecting one of the one or more first clock rates as a selected first clock rate such that an odd-multiple of the selected first clock rate is different from a carrier frequency of a positioning signal that is received from a global positioning system; and
setting a clock rate of a second memory to the selected first clock rate in response to a detection of the user input;
starting a timer for a predefined period of time after the clock rate of the second memory has been set to the selected first clock rate; and
maintaining the selected first clock rate as the clock rate of the second memory until after the predefined period of time has passed.
4. The method of claim 3 , further comprising:
storing one or more second clock rates in the first memory;
selecting one of the one or more second clock rates as a selected second clock rate such that an odd-multiple of the selected second clock rate is different from a carrier frequency of a positioning signal that is received from a global positioning system; and
setting a clock rate of a main control to the selected second clock rate in response to a detection of the user input.
