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. 用于处理随机接入过程的系统、方法和软件。在一个实施例中，接入网元件存储MTC预留模式，该MTC预留模式定义其中MTC被允许的至少一个MTC开启间隔，并且定义其中MTC被允许的至少一个MTC关闭间隔。在MTC开启间隔期间，接入网元件接收来自MTC设备的用于随机接入过程的前导码，并且响应于前导码而执行用于MTC设备的随机接入过程。接入网元件检测从MTC开启间隔到下一MTC关闭间隔
