Methods and systems are provided for carrier selection based on probable mobility of packet flow. A request is received from an access terminal. The request comprises a packet-flow-type indication, and indicates that the access terminal is requesting a packet flow. If the packet-flow-type indication is associated with a high degree of mobility, the first access terminal is instructed to conduct the packet flow on one of a first set of one or more carriers. If the packet-flow-type indication is associated with a low degree of mobility, the access terminal is instructed to conduct the packet flow on one of a second set of one or more carriers. No carriers are elements of both the first set and the second set.
