  • Publication number: 20230147931
    Abstract: In some implementations, a method includes receiving a connection request from a user application. A service request is sent to a radio resource control (RRC) module. An indication of failure of or a rejection to the service request due to access class barring is received from the RRC module. A retry of the user application connection request is prevented until expiration of an access-class-barring timer of the RRC module that resulted in the access class barring.

  • Publication number: 20200382999
    Abstract: A vehicle includes a plurality of telematics control units (TCUs) and a processor. The vehicle may use the processor to consider vehicle variables, responsive to a data transfer request, including power usage constraints, data usage over a billing cycle for each carrier associated with a given TCU, and transfer timing requirements for a given data transfer request. Based on the considered variables, the vehicle may select at least one controlling variable and select at least one of the TCUs based on at least a value of the controlling variable, then use the selected TCU to fulfil the data transfer request.
