6. The method according to one of claims 1 to 5, wherein the 4G base station is a 4G home base station, the 3G base station is a 3G home base station, and the 3G base station gateway is a 3G home base station gateway.
7. An apparatus for reporting an IMSI, comprising:
the base station simulation module is used for locally simulating a 3G base station in the 4G base station;
the IMSI acquisition module is used for acquiring the IMSI of the 4G user terminal when the 4G base station judges that the preset IMSI reporting condition is met;
the IMSI reporting module is used for the 4G base station to control the 3G base station to interact with the 3G base station gateway, sending reporting information carrying the IMSI to the 3G base station gateway through the 3G base station, and reporting the IMSI to the 3G base station gateway;
the IMSI reporting module is specifically configured to trigger the 3G base station to send a terminal registration request carrying the IMSI to a 3G base station gateway by the 4G base station, and report the IMSI to the 3G base station gateway from the 3G base station.
8. A base station comprising a memory, a processor and a communications bus, the memory and processor being connected by the communications bus, the memory having stored therein program instructions which, when executed by the processor, carry out the method of any of claims 1 to 6, the processor executing the program instructions.
9. A storage medium having stored therein program instructions which, when executed by a processor, carry out the method of any one of claims 1 to 6.
