Access method and system for MTC device, and MTC device

摘要

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.

1. An access method for a Machine-Type Communication (MTC) device, comprising the steps of:
an MTC device sending, when performing a channel request, a channel request cause value and a random reference value to a Base Station Subsystem (BSS); and the BSS sending, after completing channel allocation, the received channel request cause value and random reference value back to the MTC device; the MTC device judging whether or not the received channel request cause value and random reference value are the same as the channel request cause value and random reference value sent by the MTC device itself, if so, determining that the received channel request cause value and random reference value are intended to be sent to the MTC device itself, otherwise determining that the received channel request cause value and random reference value are not intended to be sent to the MTC device; wherein the channel request cause value is used to indicate whether or not a cause of the channel request needs to use an MTC service.
