The present application discloses a message processing method, an MME selection method and apparatuses. The method includes: receiving, by a mobility management entity (MME), a first message sent by an evolved NodeB (eNB), where: multiple virtual machines are deployed in the MME; the first message includes a non-access stratum (NAS) message sent by user equipment UE and identification information of a target virtual machine; and the identification information of the target virtual machine is generated by the target virtual machine in the MME; determining, by the MME according to the identification information of the target virtual machine, the target virtual machine from the multiple virtual machines, and allocating the NAS message to the target virtual machine for processing; and returning, a first response message generated by the target virtual machine to the eNB, so that the first response message is sent to the UE by using the eNB.
