Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates broadly to communication equipment and communication methods, and particularly to terminal communication equipment such as mobile telephones and landline telephones and their systems. It is something.

In particular, it is used for telephone systems that use low-power mobile telephones that do not place a burden on the power supply and a plurality of relay stations to support them.

[Prior Art] Currently, the Ministry of Posts and Telecommunications is promoting a plan to install a large number of microcells nationwide and use them as a mobile communication network in a consumer telephone system.

Meanwhile, the Ministry of Posts and Telecommunications is promoting a plan to use communications systems based on satellites and unmanned and manned aircraft relays as mobile communications networks for civil telephone systems. [Problem to be solved by the invention Microcell communications or personal telephones use weak radio waves, usually less than 100mW, centered on the megahertz band. The advantage of this is that it is almost the same as a cordless phone, the equipment is cheap, and health problems due to electromagnetic waves are less likely to occur. Even when using the same frequency, interference is unlikely to occur and radio wave usage efficiency is high. The battery of the late '4 model is small and good.

The problem is the method of connecting the posts. In other words, the central boss (master station,
(relay points) must be connected by wire.
Therefore, it merely changed fixed station communication to mobile communication, and did not eliminate the huge communication line network of conventional wired communication, so it could not contribute to cost reduction in any way. In addition, while there are many advantages to communication using unmanned and manned aircraft relays, there are also many disadvantages. That is, the overall equipment cost for communication with floating objects such as aircraft is low. However, terminals installed on the body must emit strong radio waves, and electromagnetic radiation health problems are unavoidable. Furthermore, since the terminal must send radio waves to airborne objects such as aircraft flying in the far-off N-range, it requires a powerful t-source for emitting high-power radio waves.

On the other hand, satellite communications are very expensive. Moreover, it has all the disadvantages that are even stronger than those of airborne vehicle communication such as aircraft. [! !

The operation of the communication group described above is as described in the operation of the first invention above. Furthermore, the operation of the relay cell communication method for an airborne object such as an aircraft according to the fifth invention will be described. This invention is based on the following points: First, a group of cell communication stations installed in various places as a network has separate jurisdiction over a large number of terminal communication devices such as mobile telephones and fixed-line telephones.

[Example] Below, an embodiment of the relay cell communication device and communication method for an airborne object such as an aircraft according to the present invention will be described along with the accompanying drawings! Let me explain in detail. FIG. 1 shows a schematic diagram of an embodiment of a relay cell communication device for an airborne object such as an aircraft according to the present invention. FIG. 2 shows a plan view of one embodiment of a cell communication network. Third
The figure is another real M! An example array diagram is shown. First, I will explain the device. First, there are a large number of mobile telephones TI-Tn. This mobile phone T! ~Tn may be used as a landline telephone. Next, there is a group of microcell communication stations Ml-Mn located on land and on the sea with a radius of up to about 500 m. This microcell communication station group M1-
Mn is provided as a network in various locations, and divides and controls the above-mentioned large number of mobile telephones T1 to Tn, and performs wireless communication with a group of terminal communication devices within its own jurisdiction. Then, there is a manned aircraft radio communication relay station A. This manned aircraft wireless communication station A communicates wirelessly with all of the microcell communication station groups M1 to Mn described above. Of course, this aircraft radio communication relay station A may be unmanned. In this case, the terrestrial relay station group Rl-Rn

The configuration may be such that all of the aircraft and the aircraft radio communication relay station A can communicate wirelessly. Roughly speaking, the aircraft radio communication relay period A is the above movement tg.
It is also possible to send directly to the i-machine TI-Tn. In other words, the transmission power of these mobile telephones Tl to Tn is very weak, so they cannot directly transmit to the aviation wireless communication relay station 8, but the reception is independent of the power and is called indirect reception. This is because the system becomes M-elementized if the signal is received directly without going through a complicated route. In addition, the above-mentioned terrestrial WR group Rl~Rn is not only one stage, but also a terrestrial relay station that has jurisdiction over these terrestrial relay stations Rl~Rn by further dividing them.

Next, an example of the communication method will be described. This invention is based on the first feature that a group of cell communication stations C1 to Cn, which are installed as a network on land and on the sea, is connected to a large number of mobile phone stations. @
It has separate jurisdiction over machines T1 to Tn. Then, it enables wireless communication with a group of terminal communication devices within its jurisdiction. Furthermore, an aircraft radio communication relay station Al is provided to enable direct radio communication with all of the above cell communication station groups CI-Cn. Note that instead of this, these cell communication station groups 01 to C
Wireless communication may be possible through each group of relay stations that have separate jurisdiction over n. Furthermore, by wirelessly communicating from this aircraft radio communication relay station 8 to the switching station S, the above-mentioned mobile telephones Tl-Tn are exchanged using their telephone numbers. In this way, one of the mobile telephones 11TI-Tn mentioned above is
First, among the cell communication stations nC1 to Cn, the cell communication station under its own jurisdiction, the aircraft radio communication relay station A, and the switching station S
And then again, through aircraft radio communication relay station A,
The line route directly to the target mobile phone is completed. In the present invention, a group of cell communication stations is defined as a group of mobile communication stations within a cellular area Cl to Cn (area) within a radius of approximately 500 m, as shown by a large number of circles in FIG. 4t
A small-scale relay station that covers eight aircraft, and is a network of stations that transmits signals directly or through parent relay circuits to airborne radio communication relay stations such as aircraft. In this way, by preparing multiple communication groups as described above and establishing a communication network between aircraft radio communication relay stations, wide area communication becomes possible. [Effects of the Invention] The relay cell communication device and communication method for airborne objects such as aircraft according to the present invention combine aircraft communication microcell communication or personal telephone, and therefore have great economic effects.
The effect on profits and health was demonstrated. Especially microcell communication.
Moreover, personal telephones do not suffer from interference due to electromagnetic waves, and even when using the same frequency, interference is less likely to occur, making the use of radio waves more efficient. In addition, the terminal's battery can be small, making it easy to downsize. Listed below are the following: a) The entire system can be constructed with low equipment costs.

In other words, there is no need for a huge wired network. b) Freedom from the dangers of electromagnetic interference in current mobile communications. C) Communication is possible even in emergencies such as earthquakes.・d) No need for telephone poles, which is aesthetically pleasing. e) There is no lag in satellite communication conversations. In other words, since it is not a long-distance communication like satellite communication, the communication will not be delayed by a fraction of a second and cause any inconvenience to the conversation. This shows the floor plan. FIG. 3 shows an arrangement diagram of another embodiment. A...Aircraft radio communication relay stations Ml-Mn...Microcell communication station group R I-R
