Abstract:
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.
