One of the functions is a telephone number memory function, so-called memory dial. The memory dial is a function of storing a telephone number that is frequently called in a memory of the telephone, displaying a desired telephone number on a calling display when necessary, or automatically dialing the telephone number. Normally, in a mobile radio telephone system, “broadcast information” such as information on a control channel structure, information on determination of a standby channel, and regulation information is set separately from a physical channel for communication from a base station to a mobile terminal. The broadcast is always broadcasted through the control physical channel, and the mobile terminal receives the broadcast information intermittently. Examples of the message related to the telephone number in the broadcast information include, for example, US PCS.
(Personal Communication System) PACS (Persona
l In a mobile communication system based on the Access Communication System), "emergency telephone number information" is included. Also, in Japan, one of the broadcast information in the digital car telephone system (RCR STD-27D) includes an "extended information element" (RCR STD-27D).
D-27D Table 4.3.5.2-24), the message content of the extended information element conforms to the standard (RCR STD-
Although not specified in 27D), it is proposed to include telephone number information. This proposal is to add the telephone number information of a specific facility in the area identified by the location information such as the "network number" and "location number" of other messages in the broadcast information from the base station to the extended information element. The mobile terminal receives the extended information element and holds the telephone number information in a memory dial for use. FIG. 6 is an example of a telephone number held in the memory dial shown in the above proposal. In the figure, for example, a memory a is a taxi company, a memory b
, A post office in memory c, a telephone number of a bus company in memory x, and the type of facility stored in each memory does not change even if the mobile terminal moves from one location to another. Absent. That is, in each region, the telephone numbers of taxi companies, hospitals, post offices, and bus companies of a, b, and x are always updated based on information from base stations. It is memorized. Therefore, if you call the number a wherever you are, you can call a taxi irrespective of where you are or what your phone number is.

However, the conventional memory method described above has the following disadvantages. That is, since the base station constantly transmits the broadcast information through the control physical channel, transmitting the telephone number information in the broadcast information has a problem in that the use efficiency of radio waves is low. Also, the mobile terminal updates the telephone number information in an area where the mobile terminal temporarily passes, although the telephone number information of the area is not necessary, and as a result, the internal processing of the mobile terminal is not performed. There was also a problem that battery consumption increased sharply. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and it is an object of the present invention to improve the efficiency of use of radio waves in a mobile radio system, and to store peripheral telephone number information while preventing battery consumption of a mobile terminal itself. The aim is to provide a method.

[0004]

In order to solve the above-mentioned problems, according to the present invention, telephone number information transmitted from a base station is received and stored in a memory, and a desired telephone number is read from the memory. A mobile telephone terminal that reads and uses information receives the telephone number information via a communication physical channel only when requested to a base station, and stores the telephone number information in a memory. According to the invention of claim 2, in a mobile telephone terminal which stores telephone number information of a plurality of areas in a memory in advance and reads out and uses desired telephone number information from the memory, based on broadcast information from a base station, Thus, the current position of the mobile telephone terminal is obtained, the area to which the current position belongs is specified, and that of the area is selected from a plurality of pieces of telephone number information stored in the memory.
