The global broadcast parameters include at least one synchronization value and one or more global parameters based on the capabilities of both the broadcaster and the observer comprising: a minimum network advertising broadcast interval between sequential network advertising broadcasts, a minimum network advertising broadcast synchronization, MinNABS offset comprising a minimum interval between transmission of a synchronization value and the network advertising broadcast, and a maximum network advertising broadcast synchronization, MaxNABS, offset comprising a maximum validity time-period for a synchronization value. In this way, replay attacks which spoof the broadcaster may be prevented.

Abstract: A method includes communicating a first fragment of a message between the vehicle and the off-board system via a first communication channel having a first throughput, a first transfer rate, a first latency, a first path loss ratio, and a first inter-packet delay variation. The method detects, by the vehicle, availability of a second communication channel having at least one of a second throughput higher than the first throughput, a second transfer rate greater than the first transfer rate, a second latency less than the first latency, a second path loss ratio less than the first path loss ratio, or a second inter-packet delay variation less than the first inter-packet delay variation.

Abstract: A method of controlling communications includes at a server determining a current vehicle geographic location, determining a communications channel is available for the vehicle at the determined current vehicle location, dynamically adjusting a maximum transmission unit, MTU, used by the vehicle for communications over the available communications channel based on a predicted optimal MTU determined from a current time and geographic location of the vehicle. The adjusted MTU setting may be dependent on whether a communications comprises a mobile originating, MO, message sent by the vehicle or a mobile terminating, MT, message received by the vehicle, and sending the adjusted MTU for the satellite communications channel to the vehicle. The dynamic adjustment of the MTU increases the data volume which can be communicated between the vehicle and a communications satellite using the respective current or next available satellite-communications channel.

Abstract: A method is performed by a vehicle system for enabling service offering content data to be provided to an interface device associated with a vehicle. The vehicle system obtains vehicle event data from the vehicle and obtains service offering data. The service offering data comprises service offering content data and service offering correlation data. The vehicle system compares at least a part of the vehicle event data with at least a part of the service offering correlation data. When a result of the comparing fulfills a criterion, the vehicle system determines a time for providing at least a part of the service offering content data to an interface device associated with a user of the vehicle.

Abstract: A method is performed by a vehicle system for handling configuration of a vehicle. The vehicle system obtains a request for a service to be provided on-board the vehicle. The vehicle system compares a current configuration with a required configuration of network capabilities that the vehicle is required to have to be capable of hosting the service. The network capabilities comprise one or more containers and/or one or more logical networks connecting containers to one another and/or to one or more offboard resources. When a result of the comparing indicates that the current configuration is different than the required configuration, the vehicle system triggers the vehicle to reconfigure its current configuration of network capabilities such that the vehicle comprises the required configuration of the network capabilities and is thereby capable of hosting the service.
