ACCESS METHOD AND SYSTEM FOR MACHINE-TYPE COMMUNICATION TERMINAL AND MACHINE-TYPE COMMUNICATION TERMINAL

摘要

An access method and system for Machine-Type Communication (MTC) terminal and an MTC terminal are provided by the present invention. The method includes the following steps: the MTC terminal sends a channel request cause value and a random reference value to a Base Station Subsystem (BSS) when requesting channels (100), and the BSS sends the channel request cause value and random reference value received back to the MTC terminal when finishing the 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 channel request 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 operation of large numbers of MTC terminals, and avoiding the influence of random reference value collision on the normal realization of original service.
