Claim:
1. A secure mobile communication relay, comprising: one or more units stored in memory, configured and executed by a hardware processor using an algorithm, the algorithm which when executed, causing the processor to perform the one or more units, the one or more units comprising: a baseband processing unit for the baseband modulation/demodulation of the mobile communication signal transmitted between a terminal and a mobile communication network base station so as to extract baseband data; a control unit for determining whether or not a set security policy has been violated, the determination being performed by analyzing the baseband data and the control unit for determining whether to permit or reject the relay of the baseband data based on the determination; a storage unit for storing information for setting the security policy; and a firewall function unit for determining, based on instructions of the control unit, whether or not the packet data included in the baseband data violates the security policy, wherein in response to determination of the packet data to be violating the security policy, the control unit operates to transmit a PDP context deactivation request signal to the terminal and the mobile communication network base station.
