ACCURATE GNSS TIME HANDLING IN DUAL/MULTI-SIM TERMINALS

摘要

Method, apparatus, and computer program product example embodiments are disclosed for improving the speed and sensitivity of position determination by wireless communication devices using assisted Global Navigation Satellite Systems (A-GNSS). Example embodiments include multi-SIM mobile wireless devices having an A-GNSS location detection capability, with one or more RF modems that may communicate with one or more wireless carriers.

主权项

1. An apparatus, comprising:
at least a first SIM module configured to access a first wireless carrier and a second SIM module configured to access a second wireless carrier; at least one RF modem configured to communicate with the first and second wireless carriers; at least one global navigation satellite system (GNSS) receiver; at least one processor; at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: cause first assisted GNSS wireless signals to be received by the at least one RF modem from the first wireless carrier using the first SIM module; cause second assisted GNSS wireless signals to be received by the at least one RF modem from the second wireless carrier using the second SIM module; and cause the at least one RF module to periodically switch between using the first SIM module and using the second SIM module to periodically switch between receiving first assisted GNSS wireless signals from the first carrier or receiving second assisted GNSS wireless signals from the second carrier.
