1. At least one computer-readable storage medium, excluding transitory signals and carrying instructions, which, when executed by at least one data processor of a mobile device in a cellular telecommunications network, cause the mobile device to:
determine a first radio access technology (RAT) priority order at a first geographic location of the cellular telecommunications network;
determine whether the mobile device is connected to the cellular telecommunications network using a first RAT in the first RAT priority order,
wherein the first RAT is a highest priority RAT in the first RAT priority order,
wherein the mobile device is compatible with the first RAT, and
wherein determining the first RAT priority order at the first geographic location comprises at least one of:
determining a number of frequency bands available to one or more RATs at the first geographic location,
determining an aggregate bandwidth for the one or more RATs at the first geographic location,
determining a highest quality of service for the one or more RATs, or
receiving the first RAT priority order from a node in the cellular telecommunications network;
connect to the cellular telecommunications network using the first RAT in response to determining that the mobile device is not connected to the cellular telecommunications network using the first RAT; and,
transmit and receive communication signals using the first RAT, and
wherein determining the first RAT priority order at the first geographic location comprises determining a number of frequency bands available to one or more RATs at the first geographic location, determining a bandwidth for each one of the number of frequency bands, and ranking the one or more RATs based on the number of frequency bands and the bandwidth.
