  • Access method and system for MTC device, and MTC device
    Patent number: 9144089
    Abstract: The present invention provides an access method and a system for a Machine-Type Communication (MTC) device, and an MTC device. The method comprises the steps of: an MTC device sending, when performing channel request, a channel request cause value and a random reference value to a Base Station Subsystem (BSS) (100), and the BSS sending the received channel request cause value and random reference value back to the MTC device when completing channel allocation (101). The present invention distinguishes the MTC services from other non-MTC services through the channel request cause value, that is, when the cause values are different, the collision will not occur even if the random reference values are the same, thus reducing the probability of the random reference value collision, implementing the effective management for access operations of large numbers of MTC devices, and avoiding the influence of random reference value collision on the normal implementation of original services.
