Abstract: A method and a system for transmitting subscriber identity information, and a network device are provided. The method includes: receiving a subscriber identity request message from a Mobility Management Entity (MME); encrypting an International Mobile Subscriber Identity (IMSI) of a User Equipment (UE) to generate a cipher text; and sending a subscriber identity response message that includes the cipher text of the IMSI to the MME. The method and the system for transmitting subscriber identity information, and the network device adopts the technical means that, the IMSI of the UE is encrypted to generate a cipher text which is fed back to the network device, thereby overcoming the problem in the current subscriber identity authentication mechanism that the IMSI of the UE is very easily resolved, so that the technical effect of transmitting the subscriber identity confidentially is improved.
