NETWORK-COORDINATED DRX TRANSMISSION REDUCTION FOR A NETWORK ACCESS DEVICE OF A TELEMATICS-EQUIPPED VEHICLE

摘要

A system for reduction of discontinuous-receive (DRx) transmissions for a network access device (NAD) of a telematics unit of a telematics-equipped vehicle includes: the telematics unit, configured to determine whether vehicle ignition of the telematics-equipped vehicle is on or off, the telematics unit further comprising the NAD, the NAD being configured to communicate with a network entity to perform a periodic updating procedure; the network entity, configured to communicate with the NAD for performance of the periodic updating procedure. The NAD and the network entity are further configured to reduce a frequency at which the periodic updating procedure is performed for the NAD in a DRx state relative to the frequency at which the periodic updating procedure is performed for the NAD in a vehicle ignition-on state.

1. A system for reduction of discontinuous-receive (DRx) transmissions for a network access device (NAD) of a telematics unit of a telematics-equipped vehicle, the system comprising:
the telematics unit, configured to determine whether vehicle ignition of the telematics-equipped vehicle is on or off, the telematics unit further comprising the NAD, the NAD being configured to communicate with a network entity to perform an updating procedure; and the network entity, configured to communicate with the NAD for performance of the updating procedure; wherein the NAD and the network entity are further configured to reduce a frequency at which the updating procedure is performed for the NAD in a DRx state relative to the frequency at which the updating procedure is performed for the NAD in a vehicle ignition-on state.
