Embodiments of the present invention relate to a method and a system for obtaining an international mobile equipment identity of a mobile station and a base station controller. The method in this embodiment of the present invention includes: sending, by a base station controller, a request message to a core network device in a manner of an unnumbered information frame; receiving, by the base station controller, an accept message of the request message sent by the core network device; sending, by the base station controller, an identify request message, where a frame sequence number of the identify request message is the same as a frame sequence number of the accept message; receiving, by the base station controller, an identify response message sent by the mobile station; and re-sending, by the base station controller, the request message to the core network device in the manner of an unnumbered information frame, where a frame sequence number of the re-sent request message is the same as a frame sequence number of the identify response message. The method in the embodiments of the present invention can avoid a problem of N(U) inconsistency between a mobile station and a serving GPRS support node that is caused when a base station controller actively queries the IMEI of the mobile station. |
