Random access channel resource configuration method and system

The invention provides a random access channel resource configuration method and system, and relates to the field of communication. The method and the system solve the problem of MTC (machine type communication) UE (user equipment) access in an LTE/LTE-A (long term evolution/ long term evolution-A) system. The method comprises the following steps that a first node sends random access channel resource configuration information to a second node, and the random access channel resource configuration information is indicated by one piece or a plurality of pieces of random access channel configuration information. The technical scheme provided by the invention is applicable to an LTE/LTE-A network, and the random access channel resource configuration on the MTC UE in the LTE/LTE-A system is realized.
