Method and equipment for selecting core network equipment

The invention discloses a method and equipment for selecting core network equipment. The method comprises the following steps that: access network equipment determines the equipment type of UE (user equipment); if the equipment type is MTC (machine type communication) UE, the access network equipment determines an MTC group identifier corresponding to the UE; and if the MTC group identifier corresponds to core network equipment, the access network equipment selects the core network equipment corresponding to the MTC group identifier as the core network equipment to which the UE accesses. In the embodiment of the invention, multiple MTC UE corresponding to the same MTC group identifier can select the same core network equipment to access a mobile communication network and can further use the public load bearing so as to save the network resources and reduce the signaling overhead.
