Abstract
A method and system is disclosed for reactively managing dropped calls in a wireless communication system. A mobile station determines that it has experienced a dropped call. In response, the mobile station allows a user to continue communicating, such as by recording the user's speech, for instance. The mobile station may then play out the recorded speech to the user or to another call participant, such as upon reestablishment of the call.
Claims21
In a wireless communications system in which a mobile station communicates with a base station via an RF air interface, a method carried out by the mobile station comprising:
- making a determination that a call in which the mobile station was engaged has been dropped, wherein making the determination comprises detecting that data has stopped flowing over the RF air interface from the base station to the mobile station, although the mobile station has not sent or received an end-of-call signal for the call;
- and
- responsive to the determination, automatically recording in the mobile station a post-call-drop speech signal provided by a user of the mobile station, wherein recording in the mobile station a post-call-drop speech signal provided by the user comprises receiving a speech signal provided by the user, encoding the speech signal as CDMA/EVRC data, and storing the CDMA/EVRC data in a data storage medium.
In a wireless communications system in which a mobile station communicates with a base station via an RF air interface, a method carried out by the mobile station comprising:
- detecting that the mobile station has experienced a call-drop, wherein detecting that the mobile has experienced a call-drop comprises detecting that data has stopped flowing over the RF air interface from the base station to the mobile station, although the mobile station has not sent or received an end-of-call signal for the call;
- responsive to the call-drop, prompting a user of the mobile station for instruction to record a speech signal provided by the user;
- receiving from the user an instruction to record a speech signal spoken by the user;
- and
- responsive to the instruction, recording a speech signal provided by the user.
A mobile station comprising:
- a processor;
- data storage;
- and
- machine language instructions stored in the data storage and executable by the processor to cause the mobile station to perform a method comprising (i) detecting that a call in which the mobile station was actively engaged has been dropped and (ii) responsively recording into the mobile station a speech signal provided by a user of the mobile station,
- wherein the machine language instructions are executable to detect that the call has been dropped by detecting that data has stopped flowing over an RF air interface from a base station to the mobile station, and wherein recording into the mobile station a speech signal provided by the user comprises receiving a speech signal provided by the user, encoding the speech signal as CDMA/EVRC data, and storing the CDMA/EVRC data in the data storage.
