Abstract
A cellular network compares the timestamps of dropped calls with the timestamps of DSDS-device transitions from the cellular network to another cellular network to identify apparent dropped calls as being transitions and not dropped calls. In this way, the cellular network avoids mis-characterizing DSDS-device transitions as being dropped calls, thereby resulting in the generation of a more-accurate drop-call rate for the cellular network.
Claims8
A method for a cellular network generating a drop-call rate, the method comprising the cellular network:
- detecting dropped calls;
- storing records of the dropped calls, each dropped-call record comprising a dropped-call timestamp;
- receiving, from at least one dual-SIM, dual-subscription (DSDS) device, at least one record of a transition from the DSDS device communicating with the cellular network to the DSDS device communicating with another cellular network, the transition record comprising a transition timestamp;
- comparing the transition timestamp in the transition record with the dropped-call timestamps in the dropped-call records to identify one of the dropped-call timestamps as being within a specified duration of the transition timestamp;
- re-classifying the dropped call associated with the identified dropped-call timestamp as corresponding to the transition;
- and
- generating a drop-call rate for the cellular network without including the dropped call associated with the identified dropped-call timestamp.
A cellular network for generating a drop-call rate, the cellular network comprising:
- a memory;
- and
- at least one processor, coupled to the memory and operative to cause the cellular network to:
- detect dropped calls;
- store records of the dropped calls, each dropped-call record comprising a dropped-call timestamp;
- receive, from at least one DSDS device, at least one record of a transition from the DSDS device communicating with the cellular network to the DSDS device communicating with another cellular network, the transition record comprising a transition timestamp;
- compare the transition timestamp in the transition record with the dropped-call timestamps in the dropped-call records to identify one of the dropped-call timestamps as being within a specified duration of the transition timestamp;
- re-classify the dropped call associated with the identified dropped-call timestamp as corresponding to the transition;
- and
- generate a drop-call rate for the cellular network without including the dropped call associated with the identified dropped-call timestamp.
