An information distribution method for distributing information to a mobile communications terminal served by a mobile communications network through said mobile communications network comprising the steps of:

• transmitting, from said mobile communications terminal, a call signal for calling another communications terminal;
• receiving said transmitted call signal in one of one or plural specific base stations which constitute a radio zone corresponding to a part of a location registration area, said location registration area consisting of a plurality of radio zones;
• performing, in said mobile communications network, a location registration process of generating information on a present location of said mobile communications terminal in said radio zone of said one base station based on said call signal received by said one base station;
• and
• distributing, from an information distribution server, said mobile communications terminal located in said radio zone of said one base station, after designating said mobile communications terminal based on the present location information generated by said location registration.

An information distribution method for distributing information to a mobile communications terminal served by a mobile communications network through said mobile communications network comprising the steps of:

• transmitting, from said mobile communications terminal, a request signal for requesting information distribution including its own identification information;
• receiving said request signal in a base station constituting a radio zone in which said mobile communications terminal is located;
• transferring said request signal, from said base station that has received said request signal to a given information distribution server, after affixing its own identification information to said request signal;
• and
• distributing information from said information distribution server to said mobile communication terminal after specifying a location of said mobile communications terminal which has requested said information distribution based on said identification information of said base station affixed to said request signal and said identification information of said mobile communications terminal included in said request signal.

A mobile communications network for performing a location registration process of generating present location information of a mobile communications terminal comprising:

• signal broadcasting means for broadcasting, from each of one or plural specific base stations that constitute a radio zone corresponding to a part of a location registration area, a radio-zone information notifying signal indicating its own radio zone, said location registration area consisting of a plurality of radio zones;
• signal broadcasting means for broadcasting a radio-zone information notifying signal indicating its own radio zone of one of said one or plural specific base stations through said each of said one or plural specific base stations;
• signal reception means for receiving through said one base station a request signal for requesting a location registration process transmitted from a mobile communications terminal which has received said radio-zone information notifying signal from said one base station;
• and
• location registration means for performing a location registration process of generating information on a present location of said mobile communications terminal in said radio zone of said one base station based on said request signal received by said one base station.

A mobile communications network for performing a location registration process for generating present location information of a mobile communications terminal comprising:
