Systems and methods for selecting data rates at which to transmit data over a primary uplink in the presence of one or more secondary uplink channels. The communication relay apparatus sets static tunnels only with communication relay apparatuses for which the frequency of handovers is high and with communication relay apparatuses for which the probability of occurrence of handovers is high, and sets dynamic tunnels with other communication relay apparatuses. The enterprise policy server determines a device trust level based on the device attribute information and a data sensitivity level based on the enterprise application, and sends a security policy to the client computing device based on the device trust level and the data sensitivity level.
