1. A method, comprising:
- receiving, by a machine type communication device;
an indication of a plurality of narrowband uplink carriers in a wideband carrier, reserved for machine type communication traffic, andat least one group of connection probabilities from among a plurality of groups of connection probabilities corresponding to the plurality of narrowband uplink carriers, wherein each of the connection probabilities in the at least one group is indicative of a probability that the machine type communication device will connect to a respective one of the plurality of narrowband uplink carriers, wherein the plurality of groups of connection probabilities are divided based on at least one of;
a machine type communication device characteristic and a machine type communication service characteristic;
storing selection priority information in the machine type communication device;
selecting a narrowband uplink carrier from among the plurality of narrowband uplink carriers for use by the machine type communication device based at least on a combination of stored selection priority information and the at least one group of corresponding connection probabilities; and
transmitting machine type communication traffic on the selected narrowband uplink carrier from the machine type communication device to a network,wherein the plurality of groups of connection probabilities comprise at least two of;
a group of connection probabilities for devices with emergency and/or high-priority data transmission;
a group of connection probabilities for devices with timed-access;
a group of connection probabilities for low-data rate devices; and
a group of connection probabilities for devices in poor coverage areas.
