Abstract: Systems, methods, and software for handling random access procedures. In one embodiment, an access network element that stores an MTC reservation pattern that defines at least one MTC-On interval where MTC is allowed, and defines at least one MTC-Off interval where MTC is prohibited. During an MTC-On interval, the access network element receives preambles for random access procedures from MTC devices, and performs the random access procedures for the MTC devices in response to the preambles. The access network element detects a transition from the MTC-On interval to a next MTC-Off interval, and determines whether the random access procedures for the MTC devices will complete before the transition. If not, the access network element modifies the MTC reservation pattern to expedite completion of the random access procedures.

Abstract: Systems and methods for sharing radio resources on an air interface. One embodiment comprises an access network element (e.g., base station) that stores a plurality of sharing patterns each comprising a different mapping of the radio resources on a physical layer of the air interface between Machine-Type Communications (MTC) and non-MTC. The access network element identifies a resource sharing window, receives input indicating conditions in the access network, selects a sharing pattern from the plurality of sharing patterns in the pattern database for the resource sharing window based on the conditions in the access network, schedules MTC transmissions on the air interface at a beginning of the resource sharing window based on the sharing pattern, and schedules non-MTC transmissions on the air interface at the beginning of the resource sharing window based on the sharing pattern.
