Problems solved by technology

[0004] In addition, under normal operating conditions, when the vehicle is moving, the cellular connection to the contracted operator may be strong in one location, but as the vehicle moves relative to the network antenna and through changing environmental conditions, A cellular connection may not be sufficient to read SMS messages to support remote actions to perform functions such as car door locks

Abstract

A method of selecting primary and secondary cellular networks for a vehicle comprises measuring cellular connectivity parameters for cellular communication between a first subscriber identity module (SIM) and a first cellular network and for cellular communication between a second SIM and a second cellular network, comparing measured cellular connectivity parameters for the first SIM to measured cellular connectivity parameters for the second SIM, designating one of the first SIM and the first cellular network and the second SIM and the second cellular network as a primary network, and designating the other one of the first SIM and the first cellular network and the second SIM and the second cellular network as a secondary network, measuring cellular connectivity parameters for the primaryand secondary networks, comparing the measured cellular connectivity parameters for the primary and secondary networks, switching designation of the primary and secondary network based on measured cellular connectivity parameters.

Description

technical field [0001] The present disclosure relates to cellular communications within a vehicle capable of utilizing multiple cellular networks. Background technique [0002] A cellular network (or cellular carrier system) provides cellular communications for various cellular devices, broadly referred to herein as user equipment (UE). In some cases, it is desirable for certain mobile user equipment to maintain a cellular connection at all times. Some locations have different levels of cellular service, and in some cases, cellular coverage in a particular location can vary based on various factors. [0003] In some vehicles, when an on-board system detects that an accident has occurred, it automatically dials a cellular phone to contact emergency services. Typically, the emergency call is initiated immediately after a vehicle collision event or when the operator of the vehicle presses the emergency button. Current systems keep trying to establish phone calls with the bac...
