    摘要： A method of re-attempting to wirelessly connect a vehicle telematics unit with a wireless carrier system includes detecting that a primary retry method has failed; and carrying out a secondary retry method that: determines whether the vehicle telematics unit will communicate using a first radio access technology (RAT) or a second RAT; re-attempts a cellular connection with one or more base stations using a first RAT attachment procedure when it is determined that the vehicle telematics unit will communicate using the first RAT; and re-attempts a cellular connection with one or more base stations using a second RAT attachment procedure when it is determined that the vehicle telematics unit will communicate using the second RAT.

    摘要： A method of removing a vehicle telematics unit from an invalid state includes sensing that the vehicle telematics unit wirelessly received an invalid state code that deactivates the communication function of the vehicle telematics unit from a base station of a wireless carrier system; determining at the vehicle telematics unit that a reset trigger applicable to invalid state codes has been activated; and commanding the vehicle telematics unit to reset the invalid state code when the reset trigger has been activated thereby permitting the vehicle telematics unit to resume its communication function.

    摘要： A method and a system of controlling a PLMN scan rate (PCR) in a vehicle telematics unit. The method carried out by the system includes the steps of: (a) determining a power condition that includes a powered mode, an unpowered mode, and a DRx mode; (b) determining whether the telematics unit is scanning one or more home networks or one or more visitor networks; and (c) setting the PCR based on the determined power condition and the determined network, including: (c1) when in the powered mode and scanning a visitor network, the PCR is set to a first scan rate; (c2) when in the powered mode and scanning a home network, the PCR is set to a second scan rate that is slower than the first rate; and (c3) when in the DRx mode, the PCR is set to a third scan rate that is slower than the second rate.

    摘要： A method of re-establishing a cellular connection between a vehicle telematics unit and a wireless carrier system includes detecting a loss of cellular connection between a vehicle telematics unit and a wireless carrier system; accessing a technology order table (TOT) that orders a plurality of radio access technologies (RATs) capable of use at the vehicle telematics unit according to desirability; attempting to re-establish the cellular connection by: determining the RAT used by the vehicle telematics unit when the loss of cellular connection was detected; searching the TOT to locate a less desirable RAT relative to the RAT used by the vehicle telematics unit when the loss of cellular connection was detected; attempting to connect with the wireless carrier system using the less desirable RAT and a group of PLMNs that is limited to home and home-equivalent PLMNs; and if that attempt fails, attempting to connect with the wireless carrier system by iterating through each of the RATs ordered in the TOT beginning with a next less desirable RAT and including in the iteration the RAT used by the vehicle telematics unit when the loss of cellular connection was detected, wherein step (c4) uses all non-forbidden PLMNs.

    摘要： A mobile vehicle communications system and a method of sending one or more secure short message service (SMS) messages using that system. The method includes the steps of: (a) determining at a sender a data quantity associated with zero or more proprietary data parcels (PDPs) to send within one or more SMS messages; (b) configuring an encrypted payload of each of the one or more configured SMS messages to carry the total number of PDPs, wherein when the size of the payload would result in an SMS message exceeding 140 bytes, the configuring step includes configuring a plurality of SMS messages to carry the payload; and (c) transmitting from the mobile originated device one or more configured SMS messages.
