Dropped call warning and prevention methods

A phone call drop prevention method, the method comprising:

• obtaining, by a processor:
• location information of a mobile terminal, or
• model and make information of the mobile terminal;
• determining, by the processor, that the mobile terminal approaches a particular geographical area not served by a first communications network, the particular geographical area being further associated with a degradation of signal;
• anticipating, by the processor:
• a distance between a current location of the mobile terminal and the particular geographical area, or
• a time period before the mobile terminal enters the particular geographical area;
• based on the determination and the anticipation, sending, by the processor, a warning signal to the mobile terminal indicating that the mobile terminal is about to enter the particular geographical area not served by the first communications network, the warning signal triggering at least one of an audio indicator and a visual indicator, the warning signal sent to the mobile terminal when:
• the distance is smaller than a threshold distance value associated with the model and make information of the mobile terminal, or
• the time period is smaller than a threshold time value associated with model and make information of the mobile terminal;
• based on the determination and the anticipation, facilitating, by the processor, a handoff procedure of the mobile terminal from the first communications network to a second communications network;
• and
• performing, by the processor, a transfer of data needed for that particular geographical area, the transfer of data associated with a navigation service provided by the mobile terminal.

A non-transitory computer-readable storage medium having embodied thereon a program, the program being executable by a processor to perform a call drop prevention method, the method comprising:

• obtaining, by a processor:
• location information of a mobile terminal, or
• model and make information of the mobile terminal;
• anticipating, by the processor:
• a distance between a current location of the mobile terminal and a particular geographical area, or
• a time period before the mobile terminal enters the particular geographical area;
• determining, by the processor, that the particular geographical area is associated with historical data associated with dropped calls, the particular geographical area being further associated with a degradation of signal;
• based on the determination and the anticipation, sending, by the processor, a warning signal to the mobile terminal indicating that the mobile terminal is about to enter the particular geographical area and that the particular geographical area is associated with previous dropped calls and a degradation of signal, the warning signal triggering at least one of an audio indicator and a visual indicator, the warning signal sent to the mobile terminal when:
• the distance is smaller than a threshold distance value associated with the model and make information of the mobile terminal, or
• the time period is smaller than a threshold time value associated with the model and make information of the mobile terminal;
• based on the determination and the anticipation, facilitating, by the processor, a handoff procedure of the mobile terminal from a first communications network to a second communications network;
• and
• based on the determination and the anticipation, performing, by the processor, a transfer of data needed for that particular geographical area, the transfer of data associated with a navigation service provided by the mobile terminal.
