A wireless communication transition die set is arranged in all fixed telephones (such as private telephones and public telephones) under the basis, so that the fixed telephone not only can be used as a general communication means, but also a low-power mobile telephone (such as a personal handy-phone system, PHS for short) under certain particular conditions (such as weak signals, being away from service areas) that wireless communication can not be carried out; then an adjacent fixed telephone can be used as a base station to form a communication connection line with other low-power/ high-power mobile telephones or between other fixed telephones through the fixed telephones or a connected wire telephone network.

Description

Improve the devices and methods therefor of its communication environment quality of power mobile phone

Technical field

The present invention is a kind of devices and methods therefor that improves its communication environment quality of power mobile phone (as: PHS), especially refer to a kind of existing fixed formula telephone network and power mobile phone itself utilized, provide a kind of power mobile phone that solves in the indoor or outdoors environment of weak signal, can not normally carry out the implementation method of communication, make in the serious place of wireless signal shielding, as long as a telephone signal interface (as: PSTN) is arranged, can make power mobile phone can keep normal communication.

Background technology

PHS is the abbreviation of Personal Handyphone System, it and GSM belong to the digital radio communication system, but it is not from the Europe or the U.S., formed but research and develop in nineteen ninety-five by Japan, belong to low electromagnetic mobile traffic, what PHS used is microcell base framework, but effectively distance radius is 100 ~ 300 meters, at power unit, because required through-put power is less, can be used on the less and lighter hand-held set, such advantage can so that for a long time talk and stand-by time all than cell system come outstanding, main application lists as follows:

(1) the secondary machine of indoor wireless: via choosing the main station that meets the a-PHS specification, just can be with the wireless servant machine of PHS as interphone.

(2) generally use radio mobile communication: be used as general mobile phone and use, but PHS also possesses the function of high speed data transfer except that possessing mobile phone transmitting-receiving sound signal.

(3) mobile office chamber radio telephone: in office, PHS can make up with the digital private exchange machine, uses as multi-functional office radio telephone.

(4) directly communication between mobile phone: between the PHS mobile phone even can directly converse, promptly do not see through the base station in short distance, can carry out communication, this communication modes generally can save many costs of the phone call, but the most important thing is to use applicable to general disaster area.

General radio area loop (Wireless Local Loop, hereinafter to be referred as WLL) system architecture, basically, it has comprised wireless terminal (or limited ustomer premises access equipment), wireless base station, exchange transmission system part, according to the difference of system, may comprise distant-end switch, DLC (Digital Looop Carrier; DLC), controller (Concentrators) or multiplex machine equipment such as (Multiplexer), and PHS is in the design of WLL, can have full duplex radio communication concurrently into main station and secondary machine, therefore respectively take a wireless radio channel, it is very narrow that the wireless telephonic frequency range of analogy is distributed in present countries in the world, its number of active lanes is limited, and user's finite capacity, thus often take place phone density bigger the time distance can occur and cross and then situation that interfere with each other or stolen.

Common air interface (the Common Air Interface that PHS is relevant, hereinafter to be referred as CAI) be that Japanese wireless system research and development centre is formulated, the function that also comprises wireless talkback between two mobile phones, CAI has comprised three broad aspect, one is wireless interface, mainly stipulated detailed standard or its working method of data-modulated carrier frequency, two is three layer signals, and three is speech coding and transmission plan.

The working frequency range of PHS is at 1895 ~ 1918.1MHz, and specific control channel is arranged, and than the application as environment such as dwelling house or offices of 40 channels of low frequency, 37 channels in addition then are appointed as the application of public's communication.PHS is the trunk that connects as system with public networks such as PSTN or ISDN, and as being connected with ISDN, the voice channel transmission digit rate of PHS can reach 32Kbit/s.

Because PHS technology rapid development in recent years, telecommunication department is widelyd popularize the PHS mobile phone, the mobile communication market of having captured quite a few with its cheap cost and cost of the phone call, the release of PHS has brought many conveniences for society really, but to be exactly the reception scope too narrow easily causes disconnected news shortcoming for main shortcoming, although the setup fee of PHS base station is used far below general mobile phone, relatively, the communication covering scope of PHS base station is not as good as the base station of general mobile phone.

The power of PHS mobile telephone base station is between 20mW ~ 500mW; wherein the covering scope of 20mW is about 100 meters; the covering scope of 500mW is about 500 meters; so contain several kilometers ~ tens of kilometers communication context compared to general mobile phone; feel dwarfed only not; so the dealer must set up intensive base station and enlarges communication context in outdoor; even but like this; under indoor environment, but often still can't carry out normal communication because signal is too weak; this shortcoming; just reduced the use enthusiasm of user to a certain extent to the PHS mobile phone, in addition, when being used in the vehicles of high-speed mobile; the reception quality also is subjected to sizable query; in fact mobile phone is not the communication system that uses when being designed to high speed originally, and signal can produce the gap when changing between two base stations, thereby produces the situation that reception is interrupted; therefore; how to improve the whole communication quality of power mobile phone in environment, this measure is the very urgent important topic that needs to be resolved hurrily of present industry in fact.

(302) subscriber dialing;

(303) content of terminal (Terminal) analyzing called number;

(304) judge whether called number is the telephone number of an external public communication network, if, continue step (306), if not, then arrive and continue step (305);

(305) be connected to a power mobile phone that is complementary with called number, directly to carry out the wireless telecommunications between handset in the group;

(306) local side (Base) is undertaken dial-up to called number by wired telephone network (as: PSTN);

(307) after called answering, local side (Base) is received the signal of answering that wired telephone network (as: PSTN) transmits;

(308) local side (Base) notice terminal (Terminal) the other side answers;

(309) conversation beginning.

In the present invention, phone has been hung up two kinds of situations, and the one, the other side is initiatively hung up, and the 2nd, terminal (Terminal) is initiatively hung up, and below is illustrated with flow chart respectively:

A, the other side are initiatively hung up flow chart, see also shown in Figure 5:

(401) during terminal (Terminal) is conversed with the external world by local side (Base);

(402) local side (Base) receives fixed-phone network (as: PSTN) and passes the hang-up signal of coming;

(403) local side (Base) sends to terminal (Terminal) and hangs up message;

(404) terminal (Terminal) receives the message of hanging up of local side (Base);

(405) end of conversation.

B, our terminal (Terminal) are initiatively hung up flow chart, see also shown in Figure 6:

(501) during terminal (Terminal) is conversed with the external world by local side (Base);

(502) terminal (Terminal) on-hook;

(503) terminal (Terminal) is sent to local side (Base) and is hung up message;

(504) local side (Base) receives the message of hanging up of terminal (Terminal);
