An encryption communication module on the side of a service providing server reports a global IP address allocated to an NAPT router on the service providing server side and a port number of an outside UDP header used on the global side to an authentication / key exchange server. When receiving an encryption packet from an encryption communication module on the user terminal side, the encryption communication module on the service providing server side overwrite a source / destination IP address of an inside IP header by a source / destination IP address of an outside IP header. The encryption communication module further changes a source port number of an inside TCP•UDP header to a unique value for each communication session in the encryption communication having the same source IP address in the outside IP header. The inverse header change is made when the packet is transmitted to the encryption communication module of the user terminal side.

A determining section (18) and gain variation amount detecting section (9) detect a period having a possibility of a DC-component offset in an internal circuit of a direct conversion receiver increasing beyond an allowable value due to AGC operation, and during the period, a cut-off frequency of each of high-pass filters (12a to 12d) is set at a frequency higher than that in general operation, thereby rapidly converging transient responses of signals passed through the high-pass filters, while controlling precisely operation timings of reception power measuring section (16), gain calculating section (22), gain control section (23) and circuit power supply control section (24) composing an AGC loop, whereby the DC offset is prevented from increasing and stable circuit operation is assured. It is thereby possible to achieve further reductions in size and power consumption of a CDMA receiver using the direct conversion receiver.
