Abstract: Menu data supplied from an IP server 500 to a mobile station 101 is embedded with a location information substitution data string “NULLAREA” together with a URL of a particular IP server 500. The mobile station 101, upon detection of the location information substitution data string from a menu data selected by the user, determines whether location information can be transmitted to the IP server 500. In the case where the determination is that the transmission is permitted, the mobile station 101 detects its location information and, after substituting the location information for the location information substitution data string, transmits the data to the IP server 500.

Abstract: Circuitry capable of controlling a bias voltage for an avalanche photodiode (APD) in accordance with the temperature slope of the breakdown voltage of the APD is disclosed. A reference voltage generating circuit sets a voltage implementing an optimal amplification ratio on an output terminal, and generates a reference voltage by taking account of the temperature slope of the breakdown voltage of the APD. The reference voltage is applied to one input of a voltage comparator. A setting circuit feeds to an adding circuit a preselected voltage for controlling the voltage on the output terminal to a value capable of implementing the optimal multiplication ratio. A temperature compensating circuit feeds to the adding circuit a voltage corresponding to the temperature slope of the above breakdown voltage. The temperature slope is representative of the variation of the breakdown voltage with respect to temperature.
