Abstract

PURPOSE:To connect any of private base stations, in-premises base stations and public stations to a personal communication terminal in common by dividing an ID into a common ID used in common and a personal ID used individually and combining the common ID and the personal ID. CONSTITUTION:An ID is divided into a common ID used in common for the connection with a private base station, an in-premises base station and a public base station and a personal ID used individually for the connection with the private base station, the in-premises base station and the public base station, and any of the private base station, the in-premises base station and the public base station is connected to a personal communication terminal through the combination of the common ID and the personal ID. For example. a personal communication terminal is called by using the common ID even when the personal communication terminal stays in any of a home, an office, a company, outdoor or on a street.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a personal communication system in which a person communicates while moving with a personal communication terminal such as a mobile terminal, and a base station installed in a home or the like; The present invention relates to a system in which a personal communication terminal can be commonly connected to a private base station connected to a private branch exchange, a public base station installed on the street, etc.

[Conventional technology]

Conventionally, in this type of system, as shown in Fig. 3, in homes, etc., a first base station, such as a main station for a cordless phone, is connected to a switching center in the public network via a wired line. A private base station (hereinafter referred to as a private base station); (hereinafter referred to as an on-premises base station), and in outdoor areas, a third base station (hereinafter referred to as a public base station) connected via a wired line to a switching center included in the public communication network, and those base stations. It consists of a personal communication terminal connected to the base station via a wireless line, and the ID used for connection with the private base station, on-premises base station, and public base station is as shown in Figure 2. As shown in the example, each system was configured uniquely. In addition, in the case of a general cordless phone, the device identification ID is about 20 bits to 30 pints.
Although there are many examples of configuring an ID using , the specific method of configuring an ID varies depending on the system.

That is, as shown in the example of FIG. 2, the configurations of IDs for identifying private personal communication terminals and IDs for identifying office personal communication terminals were different.

[Problem to be solved by the invention]

In this way, in the past, IDs used for connection with the above private base stations and on-premises base stations were configured uniquely for each system, so personal communication terminals could be connected to the above public base stations, private base stations, or Although I was able to connect to one of the base stations within my premises, I was unable to connect to the other base stations.

[Means to solve the problem]

In order to solve the above-mentioned drawbacks, the present invention provides the structure of an ID used for connection: a common ID section used in common for connection with the private base station, on-premises base station, and public base station, and an individual ID section used individually. ID parts, and by combining these common ID parts and individual ID parts, any of the private base stations, on-premises base stations, and public base stations can be commonly connected to the personal communication terminal. and a common ID section;
In addition to a basic ID section consisting of an individual ID section, an extended ID section is provided, and by using this extended ID section, it is possible to realize any advanced service function unique to each system.

〔Example〕

FIG. 1 shows a first embodiment of the present invention, in which a public communication network including one or more exchanges and one or more exchanges connected to this exchange via a wired line are used outdoors. A public base station (used by an unspecified number of people); in homes, etc., one or more private base stations (e.g., a master station for cordless telephones) connected to the above exchange via a wired line; in businesses, etc., 1 A private branch communication network including the above private branch exchange, and one or more private base stations (
It consists of a personal communication terminal (common) that is connected to the terminal (used within the office) via a wireless line.

In the embodiment of the ID configuration shown in FIG. 4, the ID includes a common ID section commonly used for connection with the private base station, the on-premises base station, and the public base station, and the private base station or the on-premises base station. It is divided into individual ID parts that are used individually for connection with base stations or public base stations, and by combining these common ID parts and ID parts, any of the private base stations and public base stations can connect to the personal communication Can be commonly connected to terminals.

Specifically, for example, if you use a common ID (equivalent to an individual's name) to make a call, you can make a call whether you are at home, inside a business/office, or outdoors/on the street, and you can connect to one personal communication terminal in common. can. In addition, for example, if you want to call the terminals of all family members in common at the household level, you can use not only the common ID part (corresponding to the individual name) but also the individual ID part to call the terminals of all family members by family name. It is also possible to call them in common.

For example, in a business office/office, if you want to call the department/section, you can call the department/intelligence using the individual ID section.

Furthermore, as shown in the example of the ID configuration in FIG.
If an extended ID section is provided in addition to the basic ID section consisting of a common ID section and an individual ID section, any service function can be realized using this extended ID section. In other words, for example, in offices/offices, etc., there is a need for highly functional personal communication terminals that can call multiple terminals at once and respond from any terminal, or can arbitrarily put calls on hold or transfer calls. In some cases, using the extended ID section,
Various IDs can be set, such as the IDs of multiple terminals making calls and the IDs of hold/transfer destination terminals, so any advanced service function can be realized independently for each system, making it easy to use at home, at work, or outside the home/workplace. While ensuring common accessibility, flexibility in design for each system can be ensured.

〔Effect of the invention〕

According to the present invention, the owner of a personal communication terminal can communicate with a particular individual wherever he or she is. It also has the advantage of being able to implement advanced service functions and ensuring common accessibility at home, business, and outdoors.
