The device parses the SA file to determine a list of services identified in the SA file, and receives a selection of a priority service from the list of services. The device updates a priority counter associated with the priority service based on the selection. The device receives, after the period of time, information indicating entry into the service area, and determines that the priority counter satisfies a threshold based on receiving the information indicating entry into the service area. The device automatically connects to a priority channel of the multicast network, associated with the priority service, based on the priority counter satisfying the threshold, and receives a priority SA file, associated with the priority service, via the priority channel. ## Claims ### Claim 1 A user device, comprising: one or more memories;
