Abstract:
A method and an apparatus for identifying a pseudo-base station in a mobile terminal. The method for identifying the pseudo-base station in the mobile terminal may include sending a LAU (Location Area Update) Request to a base station of a current cell; receiving a LAU Accept response from the base station indicating that LAU has been performed; and identifying the authenticity of the base station based on whether or not TMSI (Temporary Mobile Subscriber Identity) information is included in the LAU Accept response.

Claim (Index 19):
A method for identifying a pseudo-base station by a mobile terminal, comprising;\n reselecting, by the mobile terminal, an adjacent cell as a serving cell in response to determining a channel quality parameter of the adjacent cell is greater than a current cell; comparing a Location Area Information (LAI) of the adjacent cell and the current cell, and initiating a Location Area Update (LAU) request to a base station when the LAI of the adjacent cell and the current cell are different; identifying the base station as being a pseudo-base station in response to determining receipt of an LAU Accept response from the base station and detecting a Service Access Point Identifier (SAPI) downlink is established over a current channel by the base station with a Short Message Service (SMS) message being received from the base station via the downlink; and updating storage to identify the base station as the pseudo-base station and reselecting a previous serving cell.
