Description

PCS Personal Communications System

The invention discloses a kind of is that principal character can the whole world following PCS Personal Communications System and network technology and mobile communication technology that cover and that optional integrated information service is provided with the mobile communication.

Modern Mobile Communications Systems is as the guide of following PCS Personal Communications System, must use these medium of radio wave, generally believe and to form by radio paging system, cordless telephone system (as CT2, DECT, PHS etc.), cellular mobile telephone system (as TACS, GSM, CDMA etc.), the comprehensive developments such as (as " iridium " plan, RACE plans etc.) of earth satellite communication system.

Modern radio paging system be one cheap, the overlay area wide, as the existing frequency of reasonable use unidirectional (or two-way) numeral or literal or the speech beeper system do not limit of number of users then, it has solved the salary user's that numerous serious hopes communicates part demand in moving, but finish communication task one time, generally still need reuse telephone system, this is radio paging system user's a matter of regret.

Modern cordless telephone system be cheap, a unit are number of available channels at most, can be applicable to family, group and public telephone system, but owing to adopt the Pico cell network, realize aspect mobile phone called party and the regional covering be can not make customer satisfaction system.

Modern cellular mobile telephone system is the communication system that an overlay area is wide, business such as double-directional speech and numeral can be provided, it has solved the demand of groups of people's conversations in moving, but because system generally adopts macrocellular and microcellulor network and the complicated communication technology and equipment, system's investment is big, communication cost is higher, power system capacity is limited, is difficult to develop more mobile subscriber in many densely populated areas to making; Mobile phone waits for power and still need reduce in addition.

The earth satellite communication system is a global system for mobile communications, uses very complicated technology and equipment, and the communication cost of system is inevitable very high, and number of users is also limited.

Important step as the PCS Personal Communications System of marching toward, set up a global mobile communication net exactly, as the FPLMTS of ITU and the UMTS in Europe, their basic thought is the collection of network of above-mentioned each system and Ground Communication System, therefore its terminal must be that the set of each system terminal adds PIN, the intelligent multi mode terminal IMT that proposes as R.Steele and J.E.B.Williams; S.Chia (BTLaboratories in addition, UK) imagined a kind of hybrid cellular structure of forming by macrocellular, microcellulor, Pico cell, its key problem in technology is the handover of how fast and effeciently supporting between the different keriothecas time, to guarantee high calling integrality and call quality, cover but can not form the whole world.

The invention discloses a kind of is the principal character energy whole world following PCS Personal Communications System (abbreviation system) and network technology and mobile communication technology that cover and that optional integrated information service is provided with the mobile communication, purpose is the network configuration of optimization system and system, bring into play Pico cell respectively, the unit are user capacity advantage of microcellulor and radio call and the cheap advantage of expense, and the covering advantage of macrocellular and earth satellite space station, make it to satisfy comprehensively popularizing of personal communication and making rapid progress of Personal Communications Services, the investment cost of reduction system and cost of use improve the efficient of system and the utilance of system spectral resources.

Task of the present invention is achieved through the following technical solutions.

System of the present invention is, (be called for short terrestrial network with existing (or following) ground fixed communication network, as modern telephone net, modern ground digital fiber optic communication network etc.) be the basis, comprehensively, use for reference and (or) improve modern wireless paging network, cordless telephone network, cellular mobile communications networks, and the communication technology of other present mobile communication net such as following earth satellite communication network, construct one and satisfy that the whole world covers and the system of following personal communication demand; This system should be able to realize anyone (Whoever), at any time (Whenever), with (Wherever Anywhere, as cities and towns, rural area, ocean etc.) anyone (Whoever) carry out any form (Whatever, as data, speech, image etc.) " 5W " communication target, but and satisfying high passband and taking under the situation of less frequency, system should be able to surpass existing and potential telephone subscriber's scale economically, and also can run safely and effectively at potential travelling carriage point off density or the unusual point off density of traffic carrying capacity; System is except the mobile telephone service that routine is provided, other radio call with moving characteristic towards the individual can also be provided, Computer Data Communication, telefax, Personal Communications Services such as video telephone, and optionally towards the individual, the public and (or) integrated information service of group, as personal information processing, real-time stock market, weather forecast, topical news, group notifies from a phone call, information services such as group's news, system also can assist other system to provide two-way or the uni-directional wireless message transmission in addition, as wired scrambled TV service program selecting system, the automatic detected transmission of earth environment weather system etc.; (provide part or all of Personal Communications Services by system communication office, the communication bureau of optional personal information service, be called for short individual office, existing digital program controlled exchange can be transformed into can provide the individual of all or part of Personal Communications Services office), optionally region information centre (is called for short in country or this locality or other integrated information service centers, region, to the individual, the public or group provide country or local or other integrated information services), the global mulched ground veil that all kinds of (or zone) terrestrial network local or all interconnection (perhaps directly or indirectly interconnection) forms, system master's cellular basestation (abbreviation main website), the substation (is called for short in system sub-honeycomb base station, optionally) and other above ground portion constitute the personal communication network (zone of the optional integrated information service that following zone covers, the region is close on the meaning, refer to a city, an administrative area, a country, an area etc., but it is bigger or equal than region area that the difference of identification of the present invention is a region area), or by optionally global regional or national or other Management of Satellite Multipurpose Information service centres (abbreviation satellite information center, to the individual, the public or group provide the whole world regional or national or other integrated information services, region information centre, the satellite information center unification is called information centre), satellite station (is called for short in the satellite communication space station, main website, the substation, the satellite station unification is called the base station) etc. satellite personal communication network and the regional nerve of a covering of the optional integrated information service that covers of the other parts following whole world that form and the terrestrial network interconnection of satellite communication support to constitute the personal communication network of the optional integrated information service of following whole world covering mutually, provide two-way common signaling channel (abbreviation signaling channel) and two-way point-to-point communication channel (abbreviation communication channel) service and optional integrated information service to system's travelling carriage (comprising that other moves or fixing system wireless terminal), wherein optionally information centre also can be merged into information communication individual innings (or center) with individual office.Signaling channel and communication channel divide equally free in part and above ground portion and locate interface in the base station, aerial part comprises wireless signaling channel and radio communication channel for wireless channel, and above ground portion comprises signaling link and communication line for the exchange line of the direct or indirect ownership individual office to travelling carriage by the terrestrial network exchange (abbreviation ownership office); There are some signaling channels and some communication channels in a satellite station, the signaling link of every signaling channel and the communication line of every communication channel are generally provided by the above ground portion of satellite network, the perhaps also direct or indirect access satellite information center of satellite station in addition, when personal communication service is provided, also provide the optional public and (or) group's integrated information service; There are some signaling channels in a main website, the signaling link of every signaling channel is provided by terrestrial network or individual office, also can transmit another main website or certain satellite station wireless signaling channel, share the signaling link of other main website or satellite station, perhaps, a main website also has some communication channels simultaneously, the communication line of every communication channel is provided by terrestrial network or individual office, also can transmit another main website, or certain substation, or the radio communication channel of certain satellite station is shared the communication line of other base station as required, the perhaps also direct or indirect optional region of access information centre of some main website in addition, when personal communication service is provided, also provide the optional public and (or) group's integrated information service, other transmitting signaling main website also should corresponding forwarding integrated information; There are some communication channels a substation, the communication line of every communication channel is provided by terrestrial network or individual office, also can transmit another substation, or certain main website, or the radio communication channel of certain satellite station is shared the communication line of other base station as required, the substation is not provided to the signaling of individual office, be that the substation need not direct or indirect signaling link, but still need the wireless signaling channel to provide the communication channel service for travelling carriage, therefore the difference of main website and substation is, main website has to the signaling channel of terrestrial network or individual office, and the substation does not have this signaling channel, selects for use the substation reduction system to invest simultaneously under the prerequisite that solves the signaling transmission, simplified system network and network demand, reduced the trouble of system's increase-volume; System mainly is signaling exchange on the signaling link to the management of main website, and just simple as managing some existing fixed telephone terminals to the management of the communication channel of main website and substation, and existing terrestrial network has possessed managerial ability; System adopts several main websites and several substations to constitute the zone and covers, wherein the honeycomb of main website and substation is divided into macrocellular by the size of covering radius, the honeycomb of microcellulor and three kinds of different levels of Pico cell, each cellular footprint can cross one another, and than the honeycomb that several small radii can be arranged in the honeycomb of long radius, promptly in a macrocellular area of coverage, allow many microcellulor areas of coverage and many cellular coverage, in a microcellulor area of coverage, allow many cellular coverage, allow simultaneously a large amount of cellular footprint or the regional area of coverage in the communication coverage area of a satellite station, system adopts several satellite stations to guarantee that following whole world covers and several macrocellular main websites guarantee that the zone covers; One or several Pico cells form cellular coverage, main service high density (or temporary transient high density) Hypomobility (or temporary transient Hypomobility) or move the telex network in the place of (or isolate with extraneous radio), communication as (commercial network, hotel, exhibition center, sports ground etc.) various public's venue institute, bustling biotope, city, (aircraft of flight, the train of operation etc.) mobile place, hypogee etc., the Pico cell station is adopted substation and a small amount of main website that transmits another base station signaling channel that adopts in a large number, and covering radius is generally less than 500 meters; One or several microcellulors form the microcellulor area of coverage, the telex network of density in the main service low speed, coverage hole with a plurality of Pico cells formation of part or all of covering, as the village, the street, in the walking, on the rickshaw, the first-class communication of travelling in bustling city of vehicle, the covering radius of microcellulor is at 500-2000 rice, the transmitting power at picocell station and Pico cell station is all less, the transmitting power at Pico cell station is low slightly, the electric energy that provides as available exchange line reasonable in design, and picocell station needs bigger slightly transmitting power, and they all have very strong radio tie link is that radio transmission conditions is fine; One or several macrocellulars form the macrocellular area of coverage, be mainly used in the less zone of travelling carriage (rural area firmly etc. of loosing as peasant household), during high speed moves (train and the automobile of operation are first-class), big zone (as each district, cities and towns etc., mainly provide the two-way signaling channel service of ownership office), and partly or entirely cover communicating by letter of coverage hole that some microcellulors and some Pico cells form, its covering radius is generally greater than 2000 meters, and transmitting power is bigger, because may there be stronger multipath effect in the wireless channel of macrocellular, make its quality of wireless channel descend, so the decline that the wireless channel technology of macrocell base stations should be able to the adaptive channel quality; The global area of coverage that some satellite stations form is generally used the communicating by letter of special case such as coverage hole of (as first-class at the aircraft of flight) and terrestrial cellular formation in Yu Haiyang, the rare zone of land mobile station (as grassland, remote mountain area, desert etc.), the high-speed motion; Under particular surroundings, should adopt and to transmit mobile main website whole channels or local channel, or mobile substation, or fixing main website, or fixing substation, for travelling carriage provides channel services, as aboard, on the train, the first-class mobile place of steamer adopts the Pico cell of energy repeater satellite channel or ground main website channel to move main website or substation, and for example at basement, or large-scale hotel, the exhibition center, radio such as gymnasium cover the forwarding main website that difficult place is adopted the wireless signaling channel of energy repeater satellite station or ground main website even comprised their radio communication channel, enlarge the covering radius of ground base station for another example, or the traffic carrying capacity of personal communication in the balance area of coverage, or the area of coverage extends along road, or improve wireless transmission quality etc. and can adopt and transmit main website or substation, the aftermentioned wireless communication technology that is fit to travelling carriage is applicable to that equally also these repeating base stations are used to transmit the transceiver of wireless channel simultaneously.Wireless signaling channel and radio communication channel generally can be by satellites, macrocellular, the order of microcellulor and Pico cell or arrange or design their value (or price by the descending order of the covering radius of each base station from high to low, or use rate), considering the wireless channel forwarding, the value of the signaling channel of travelling carriage and communication channel is just not necessarily abideed by this and is put in order during the value of exchange line and different network operators' competitive price strategy, be worth (similar) as existing telephone network meaning up channel and press international long-distance to the value of systems exchange circuit, national distance, arrange from high to low the city, rate situation with reference to systems such as existing mobile phones, the value of the long-distance Pico cell channel of system generally will be higher than city macrocellular channel, and perhaps the national distance satellite channel is lower than the international long-distance honeycomb channel, therefore final channel is worth with terrestrial network much relations, for the better supply-demand relationship of the wireless channel of resolution system, system should locate the value of each wireless channel or use rate at the value of exchange line and the supply and demand situation of wireless channel; Travelling carriage is with the unique distinguishing mark of people one by one people net, the channel of supporting that this is professional (should be selected according to the needs of communication service by system as video telephone, or the like) and the situation of each available channel of travelling carriage loca select to be worth minimum signaling channel and communication channel, perhaps, travelling carriage also will be provided with several address codes that receives integrated information service in addition, allows optional information centre can authorize travelling carriage to receive the integrated information service of permission; Therefore, along with the enforcement of system with improve a large amount of communication services and will be solved by Pico cell station and picocell station, the professional need of a spot of energising solved by the macrocellular station, have only the only a few communication service to need the satellite station solution.

The base station is inserted the communication bureau, telecommunication bureau of individual office or terrestrial network etc. nearby, be dispersed in any position of the earth, and allow the operator or third party even the user that belong to different respectively in the base station of a position, therefore the investment of runing the base station along with starting of system must be disperseed, network operator as some public places (travelling carriage active point) independently sets up cellular basestation for increasing the power of self striving unexpectedly, and for example some large and medium-sized enterprise also set up the cellular basestation that covers this enterprise voluntarily in order to improve intercommunication, information management etc., or the like.In order to adapt to the needs of following Personal Communications Services, the wireless channel of system should adopt modern radio digital communication technology, also should adopt same or analogous air interface simultaneously as far as possible, therefore signaling channel and communication channel all can by after the digit regeneration of all kinds of base stations selectively the two-way changing relaying (or cry forwarding, its corresponding techniques is also uncomplicated), though traditional wireless simulation communication technology also can adopt, be unfavorable for professional quality and variation; The exchange line of system can adopt numeral or analog communication techniques, the employing of analog communication techniques generally is in order to keep and the existing compatibility of the analog lines of use in a large number (this moment, modulator-demodulator will be equipped to adapt to the needs of individual digital communication service in the base station perhaps), but Personal Communications Services the influence that will be subjected to analog line is provided, or all provide, or part provides, maybe can provide but communication quality decline, as provide visual telephone service, data transmission service or the like is along with the total digitalization analog line of terrestrial network will be eliminated by digital switched circuit gradually.The signaling link of satellite station and main website directly or the signaling network of (by certain individual office, satellite exchange, communication bureau etc.) indirect access terrestrial network, and distribute unique network number, when being established to the signaling channel of its ownership office for travelling carriage in its area of coverage, also can provide the optional public and (or) group's integrated information service, the main website that does not have a signaling link also can transmit these integrated information services when sharing other base station signaling channel; System finishes the caller signaling of travelling carriage with signaling channel, called signaling, two-way paging, short service signaling, optional integrated information service etc., because the high efficiency of digital information transmission, a zone only need distribute a spot of signaling link to insert signaling transformation task and optional integrated information service that following personal communication just can be competent at by macrocellular main website (signaling link also can insert microcellulor or Pico cell main website when serving group inside certainly) respectively, as one 3,000,000 people's big city by following design: 5,000,000 individual travelling carriages are arranged, per hour exhalation rate of peak 20%, every the signaling link per second is finished 10 callings, then there are 30 macrocellular main websites to be connected to a signaling link respectively and can finish this city's signaling transformation task, so be that signaling link or the main website placement of finishing the signaling transformation task distribution of system can settle at one go fully, and perhaps following individual innings elemental user number is that the hundreds of thousands family is more reasonable.Direct or (by certain individual office, satellite exchange, communication bureau etc.) the indirect access terrestrial network of the communication line of base station, and distribute unique network number, for travelling carriage in its area of coverage is established to the communication channel of its ownership office as required, finish the communication service of travelling carriage to personal communication network or the arbitrary node of terrestrial network.Each base station is preferably in its wireless signaling channel and broadcasts its available wireless signaling channel and the value of radio communication channel in real time periodically, the grade of service (shows the class of business that provides, generally depend on exchange line), covering radius, take information such as situation and network number, repeating base station will form the information broadcasting periodically in real time of oneself according to these information and s own situation, and system's travelling carriage according to each base station information of position particularly channel be worth and the grade of service is independently adjusted self in real time: the travelling carriage that at first is in stand-by state should be better by carrier-quality, signal stabilization, signaling channel is worth minimum, signaling transmission priority start more easily (or is waited for failure, or periodically, wish to find better signaling channel) signaling channel of searching, and wait for and allow ownership office obtain the network number that its latest position information is this signaling channel by the active signaling at this signaling channel, next travelling carriage should be sought carrier-quality periodically when waiting for or working better, be worth minimum, the communication channel of signal stabilization and covering radius minimum (or being fit to), set up the communication channel of calling and called for high-speed decision thereafter, or when dropping to certain value, communication channel quality switches communication channel (handover), or the minimum communication channel of the value that switches to latest find, or switch to another better communication channel and prepare, should choose the bigger ground based cellular communication channel of covering radius during this external handover as far as possible, can reduce the probability of handover like this, therefore the wireless channel of system is generally independently linked by travelling carriage under the base station tacit agreement cooperates, and the other parts of system are done a little aid in treatment at most; Be worth for the channel of the economic interests that are related to the user and equal wireless channel and be worth and add exchange line and be worth, its wireless channel is worth by the base station broadcast and the communication bureau that can be inserted by the base station etc. and tells the ownership office of travelling carriage by ground signaling network charging signaling, and the billing database of the travelling carriage that the value of exchange line can be pre-deposited by ownership office calculates, though the channel that obtains with ownership office that travelling carriage calculates is worth and may wait, but ownership office should guarantee the final charging that the reasonable accuracy of travelling carriage calculated value makes travelling carriage choose rational channel and ownership office and should agree with travelling carriage, the network operator can utilize channel value reasonably to strive unexpectedly simultaneously, the cost of use that rationally reduces the wireless channel of its base station as the network operator of base station attracts more travelling carriage automatically, and and for example individual office rationally reduces the cost of use of exchange line and sets up own base station so that reduce the usage charges of ownership travelling carriage channel and be used for absorbing more user and register.But, system can run into three kinds of situations when actual motion need effectively to handle, the disaster situation at first takes place, as earthquake, floods, the building catches fire etc., can cause the part communications facility to damage, the system business throughput descends, make the actual capacity of system temporarily not satisfy the communication requirement of the swift and violent accustomed business of user (as efficient service easy to use such as voice communications) that increases this moment, ask mobile stations communicating will can not find the professional communication channel of custom later on for this situation majority, change custom at them, system also can easily reach a standard when adopting efficiently means of communication, (or select the simple and easy general information sign indicating number of travelling carriage definition for use as the autonomous encoded digital information of user when disaster takes place, as reporting to the police, sign indicating number such as have no mishap) uses paging service, or the travelling carriage voice recording is sent out message such as " I are very safe now " with voice paging (or being the user speech fax) to the relatives and friends that are concerned about oneself, main website at this moment of certain system, individual office even terrestrial network also can adopt some regulation measures, only allow the outside main calling of exhaling communication and not accepting the external world in disaster area as adopting, allow superuser to adopt the higher business of digital rate, or all users must adopt the measures such as messaging service of low digital rate to ensure the unimpeded of user's basic messae transmission, but be ready to adopt the user of the satellite communication of higher rate generally not to be subjected to the restriction of this measure, these characteristics make system emergency communication perhaps be better than the emergency communication system of intelligent building, and above-mentioned regulation measure generally realized part by terrestrial network, not necessarily requires system to repeat to realize; Next is for the automobile mobile communication situation of the highway in prosperity district, the bandwidth of the working frequency range of system will be according to prosperity district communication requirement by the Pico cell reasonable disposition in general, therefore it is less being used for the bustling macrocellular communication channel of distinguishing the big covering radius that is well suited for highway automobile communication, perhaps, system will dispose the picocell station of less covering radius just can finish the bustling communication task of distinguishing fast running automobile on the highway, but can make the travelling carriage handover too frequent this moment owing to the honeycomb radius is little, for this reason should be with system base-station tandem to a PBX in the zone of reasonableness or individual office, travelling carriage is stated the network number of original communication channel earlier to the switching base station when handover, cooperate PBX or individual office to finish switching nearby by the switching base station; Tertiary system system is when adopting TDMA, the crash scenario of the professional and some high digital rates of some low digital rates (lower etc. than speech digit speed) (as video telephone etc.) when business is independently seized channel as voice or other, be that the somewhere has one to be worth minimum channel and to be occupied by the business of one tunnel high digital rate and make the business of other low digital rate can not obtain serving the service that maybe can not obtain, or somewhere channel that two or more minimum values are arranged is occupied the part time slot by a plurality of low digital rate business respectively and makes each channel all can not provide or high digital rate business can not be provided preferably, but collision is better solution under adjustment rationally or regulation and control, at first there is one to be worth minimum channel for the somewhere, low digital rate service request base station is attempted the professional slot length that reduces of the high digital rate of requirement and is avoided collision, secondly for solving the channel collision problem that the somewhere has two or more minimum values, but each each channel of base station real-time release accumulative total descending time slot duration in long-time window (is being represented average traffic in the long-time window, be called for short long window flux, the base station will long window flux be divided into several grades issues) and in the short time window accumulative total descending time slot duration (representing average traffic in the short time window, be called for short short window flux), travelling carriage is better by carrier-quality according to business demand, signal stabilization, communication channel is worth minimum, covering radius is suitable, and (motion conditions according to travelling carriage self is decided, as move and comparatively fast should select the bigger honeycomb of covering radius, long period does not have to find to move then to select the less honeycomb of covering radius as far as possible, be actually according to the situation of change of the wireless channel of periodically seeking and fixed for the mobile detection of travelling carriage), long window flux grade is minimum, the priority of short window flux maximum is selected channel and communication channel thereof, the similar service in base station amount in the area of coverage that so not only better solved collision problem but also balance, but suitable long-time window size should be selected by system, short time window size and long window flux divided rank, the present invention recommends long-time window size can select 24 hours, it approximately is the several times of single call duration time length mean value that the short time window size can be selected about 20 minutes, and long window flux grade is too much unsuitable, there is the grade about tens to get final product; In addition, the communication activity that need supspend travelling carriage in some particular surroundingss guarantees the safe operation of other system, as aircraft when taking off or land for guaranteeing near radionavigational safety other radio communication need supspending etc., therefore the base station of particular surroundings can be sent out according to actual conditions and suspend signaling or recover signaling, travelling carriage will temporarily be forbidden the working routine that transmitter is possible according to suspending signaling, but receiving that recovering signaling or time out travelling carriage when certain time length (can select about 10 minutes) is not received new time-out signaling again will recover the possible operate as normal routine of transmitter, or the employing manual control is controlled the possible working routine of transmitter of travelling carriage by everyone of travelling carriage.Travelling carriage is in the process of setting up communication channel or handover; need initiatively in the channel associated signalling of signaling channel or communication channel signaling to inform that ownership office desires to build the network number of communication channel; connect (dialling) channel wait travelling carriage access all by ownership office; travelling carriage can be well under the control of ownership office like this; and network management is simple; also prevent illegal mobile station network access well, protected the interests of each side.In addition, the individual identification sign of travelling carriage can be by following design: at first be a call number that submits to existing telephone number coding rule, comprise the international long-distance area code, the national distance area code, individual office number (being equal to local office number) and personal number (being equal to telephone number), terrestrial network and individual office are with this travelling carriage of this number call, the remainder of this sign is the authentication code of travelling carriage, be used for individual office and differentiate its travelling carriage, this authentication code is separated into two parts again, a part is the unique sign indicating number that dispatches from the factory of travelling carriage, and another part is the given identification code (or also comprising cryptographic algorithm) of individual office.

When selecting mobile communication technology, should abide by practical, efficiently, the basic principle of low consumption, do not select complicated mobile communication technology for use as far as possible, and the high and unripe mobile communication technology of selected technology content requirement, main consider to reduce that travelling carriage is waited for and the average power when launching (for bringing service time of prolonging the travelling carriage battery etc. benefit), improve Digital Transmission speed (mainly being) in order to satisfy the video telephone business, provide the continual fast optional public and (or) group's integrated information service, and multiplexing to greatest extent base station equipment, reduce the cost of various base stations and the aspects such as cost of travelling carriage, therefore wireless channel adopts F/TDMA (many weakness to be arranged also though CDMA has many good qualities, as in that improve can be not good than F/TDMA aspect the individual channel digital rate, also increased the complexity and the cost of system simultaneously) and FDD (or TDD) technology, speech coding adopts PCM, DM, simple coding schemes such as ADPCM (RPE-LTP, high-quality low code check scheme such as APC also can adopt, but perhaps future personal adopts the video telephone business that needs higher number speed more, and common in the ordinary course of things mobile telephone service system can guarantee, therefore perhaps the employing of high-quality low code check scheme can not bring much benefits for system, also can increase the complexity and the cost of system on the contrary), modern radio digital communication technology such as block code of error correction coding (or convolution code etc.); Should select the channel bandwidth of broad as far as possible, prior art is put into practice (as VideoCD etc.) and is shown, the unidirectional per second of personal TV telephone service of following better quality should have about 1 megabit or higher Digital Transmission speed, consider to adopt Ditital modulation method efficiently, then the channel lowest-bandwidth has 500KHz can satisfy the demands substantially approximately.Therefore it is considered herein that:

1. a working frequency range is adopted in main website and substation, as 900MHz etc., its bin width needs tens MHz, in a Pico cell, provide the speech channel on hundreds of road and tens tunnel video telephone channel can satisfy system requirements substantially simultaneously, satellite station can decide working frequency range in addition, because the satellite station covering radius is very big, its width needs hundreds of MHz, promptly perhaps a satellite station needs to provide simultaneously up to ten thousand speech channels could satisfy the demand of following personal communication, and this moment, perhaps system's travelling carriage needed two main transceivers that are operated in different frequency range just can finish whole world covering; Or main website, substation and satellite station adopt a continuous working frequency range, this moment, a less sub-working frequency range should be adopted in main website and substation, satellite station should adopt a bigger sub-working frequency range, and two sub-working frequency range must not intersect, and this scheme system travelling carriage only needs a main transceiver just can finish whole world covering.Working frequency range very high make travelling carriage wait for power consumption when being difficult to drop to satisfied level, preferably be thought of as satellite station, macrocellular main website and special main website (main website in the place that is used to move or isolate with extraneous radio) installment work is at the auxiliary wireless signaling carrier signaling machine of the auxiliary frequency range of lower frequency, allow travelling carriage that auxiliary receiver is installed can wait for this auxiliary wireless signaling carrier wave and receive optional integrated information and called signaling, to being this user's of sensing the automatic main transceiver work of startup of called this mobile station control unit and finishing possible called signaling, this kind scheme travelling carriage is waited for power consumption can be minimum, and can accomplish uninterruptedly to receive optional integrated information service simply; But perhaps integrated information that the auxiliary wireless signaling here comprises and called signaling are integrated information and the called signalings of having simplified, particularly called signaling may be pointed to several travelling carriages, therefore the most perfect information and signaling should be in the wireless signaling channels of base station, and more integrated information and complete called signaling should be transmitted in certain base station in auxiliary wireless signaling carrier wave when transmission is light; Satellite station, the auxiliary wireless signaling channel of macrocellular main website and special main website can adopt same channel time division technique, system is divided into tens time slots with carrier frame, the several slots that at first begins is distributed the auxiliary wireless signaling channel use of returning each satellite station, some time slots under connecing return the auxiliary wireless signaling channel of macrocellular main website to use, surplus next time slot returns the auxiliary wireless signaling channel of special main website to use, the auxiliary wireless signaling channel time slot of macrocellular main website and special main website should be synchronous with the auxiliary wireless signaling channel time slot of satellite station, and should leave time slot protection between the time slot, the channel that simultaneity factor should be chosen certain bandwidth satisfies the demand (the channel band width that the present invention estimates at 50KHz can satisfy) of the information capacity of auxiliary wireless signaling channel, and frame length was advisable with 0.5 second; Or the auxiliary wireless signaling channel of satellite station, macrocellular main website and special main website is selected the pilot frequency communication technology for use, system needs the back work frequency range that tens channels are arranged, satellite station accounts for several channels, the macrocellular main website accounts for several channels, special main website accounts for a channel, the optional 25KHz of its channel bandwidth; Or satellite station is divided into auxiliary wireless signaling channel when adopting same channel, and macrocellular main website and special main website are divided into auxiliary wireless signaling channel when adopting another channel, or the like.Satellite station and macrocellular main website need frequency planning to guarantee that the whole world covers and the zone covers, should independently use one or several channel in order not disturb other operate as normal mobile base station, base station, macrocellular main website planning simultaneously and setting can settle at one go, its regional replace mode should be more than or equal to 12 sub-district district group, can be designed to not have adjacent honeycomb frequently like this organizes frequently, reduced the anti-adjacent optionally index of disturbing promptly frequently to travelling carriage, and regional coverage hole does not almost have, but covering radius is than near the picocell station (generally more than twice) of the little manyfold of macrocellular main website, Pico cell station (multiple is just bigger) and macrocellular substation (replenish the deficiency of macrocellular master station communication channel, this moment, grand main website covering radius was generally bigger, the little several times in grand comparatively speaking substation, or adopt not other channel for the use of macrocellular main website) need not frequency planning, they can be sought automatically and be operated in and disturb on the minimum frequency, but they need initiatively avoid the channel and the adjacent channel of macrocellular main website on every side, guarantee the integrality that macrocellular main website zone covers, this scheme may be in the part among a small circle some channel with frequently and adjacent serious interference frequently, but macrocellular substation, being provided with of picocell station and Pico cell station mainly is to solve the local channel off-capacity targetedly, goal systems should be able to reach hereto, and some channel quite should be the less demanding zone of channel capacity with frequency and adjacent serious interference zone frequently, and other channel channel of system should be able to be dealt with problems.

2. there are several carrier waves each base station; but main website and substation generally have only one (TDD) or a pair of (FDD) carrier wave; several wireless channels one (to) periodically send frame by frame and receive in the carrier wave; each (to) carrier frame usually in real time distributes a pair of time slot to be used for a wireless signaling channel (to particularly point out the base station, inside that is provided with for enterprise etc.; the part of descending time slot is used to transmit the wireless signaling channel services of other base station in non-inner travelling carriage; another part is used for the internal wireless signaling channel and serves inner travelling carriage) and in real time distribution according to need is some that time slot is used for several radio communication channels; downlink frame at first is the downlink signaling time slot of a command transmitting and optional integrated information; it then is real-time demand assigned several downlink communication time slot; it at first is several uplink communication time slots of real-time demand assigned that uplink frame is subjected to the control of downlink signaling time slot; remainder is the up signalling time slot; and downlink signaling time slot; the size distribution according to need of downlink communication time slot and uplink communication time slot; this moment in the up signalling time slot is the longest in real time will to help handling more up signaling; downlink frame can be given capable channel information continuously and the time slot protection zone needn't be arranged by the base station; uplink frame is sent out uplink channel information by each travelling carriage or repeating base station then need have the time slot protection zone; the downlink frame of FDD and the cycle of uplink frame equate; and the cycle of the downlink frame of TDD and uplink frame needn't equate; its downlink frame and uplink frame constitute tdd frame; tdd frame elder generation demand assigned downlink frame; remainder is distributed to uplink frame, and the up signalling time slot of TDD generally can longlyer more help handling more up signaling like this.Downlink signaling time slot and up signalling time slot constitute the wireless signaling channel, provide the signaling service for many travelling carriages simultaneously, the downlink signaling time slot is a broadcast mode, and the up signalling time slot fights for (or when needed by downlink signaling time slot specify) as required at random by travelling carriage and repeating base station and bursts or transmit up signaling, which up signaling will be sent out in next downlink signaling time slot by the correct reception in base station is confirmed signaling, in addition, because the high efficiency of Digital Transmission and the carrier number word transmission rate of height (or higher), make the downlink signaling time slot shorter usually, and the travelling carriage when waiting for only need receive downlink signaling time slot (or auxiliary wireless signaling carrier wave), other time slot sleep power consumption can be extremely low, thus travelling carriage on average to wait for power lower.The descending time slot of each communication channel and the order of ascending time slot can be not corresponding, require the channel base station of lower (as Speech Communication etc.) should consider that the position of ascending time slot under each channel path delay inequality reasonable distribution makes the travelling carriage transmitting-receiving not overlapping in time and leave the gap during ascending time slot down for digital rate, can reduce the technical specification of the travelling carriage of service rate less demanding (as speech etc.) like this, or the travelling carriage that is operated in the substation channel of not transmitting optional integrated information service also has an opportunity to ask the position of ascending time slot under the reasonable distribution of substation, receive the optional integrated information service of other base station with a uninterrupted frequency hopping of main transceiver, simultaneously when the little then real time slot weak point of sending out of communication information amount, the communication information useless is sent out and is then sent out the time slot head, therefore the average transmit power of travelling carriage also is lower, but also has reduced the same frequency and the adjacent interference frequently of channel.The frame period of all kinds of base stations should equate, taking into account system adopt in the future low orbit satellite then travelling carriage to the delay inequality of satellite station generally also more than 10 milliseconds, but should be the smaller the better for reducing the communication delay frame period; On average wait for power consumption for what further reduce travelling carriage, can be used to expand the address code of travelling carriage to frame number, travelling carriage only need be kept the signalling time slot of listening corresponding frame number, and travelling carriage is in sleep state during other frame number; Consider the calling of the quick response individual office of travelling carriage again, the frame number cycle with about 1 second for well; Therefore the present invention is 31.25 milliseconds in the comprehensive back recommendation frame period, and the frame number cycle is 1 second, and frame number is 32, and the most important optional public or group information should repeat to broadcast in 32 frames each travelling carriage all can be received simultaneously; Adopt the base station of auxiliary wireless signaling carrier wave, the above-mentioned communication technology can adopt as usual, also will be simply with call signaling and the optional public and (or) group's integrated information merges the coding back at auxiliary wireless signaling carrier broadcast.Reason owing to radio license granting mechanisms and system access channel requirement broad, perhaps, system is difficult to obtain enough working frequency range width the implementation phase starting, therefore do following consideration according to the present invention of above-described radio digital communication technology: the lowest channel width that keeps the system in future business demand, the Personal Communications Services that is lower than and equals speech digital coding speed only is provided the implementation phase starting, do not consider mobile base station and satellite station, the communication channel number of restriction base station promptly limits the Digital Transmission speed of base station, some channels of permission are distributed to 12 or 12 after the time-division to use with last macrocellular main website be that the regional replace mode of macrocellular main website continues more than or equal to 12 sub-district district group, the macrocellular main website is broadcasting channel time-division situation periodically, other cellular basestation is sought according to the channel time-division situation of receiving and is disturbed the working time slot of the synchronous time-division time slot of minimum and macrocellular main website as oneself, as permit 2MHz, channel size 500KHz, adopt FDD, each channel is divided into the long time slot of 10 3.125mS by the 31.25mS one-period, then there are 20 time-division time slot allocation to use for each cellular basestation, when this method is accepted to obtain easily enough system works bin width and is come implementation system whole professional by society in system, existing macrocellular main website of system after new system parameters is set and other base station will still effective together, and the travelling carriage with the complete compatibility of following system can be provided on the business that can provide travelling carriage fully.

3. each channel time slot Dynamic Selection Ditital modulation method, digital coding method, digital signaling speed and time slot size etc. as the case may be; Should consider the high reliability transmitted and can simple and easy low power consumption digital demodulation for the signalling time slot, Digital Transmission speed can suitably reduce, and allows to adopt poor efficiency Ditital modulation method, high anti-interference coding method, continuous two frame re-transmissions; Business for high digital rates of need such as high quality video telephones, at carrier wave high s/n ratio (common visual and near radio channel, as Pico cell, microcellulor) situation lower channel time slot adopts the high-efficiency digital modulator approach, high digital signaling speed, distribute the time slot of broad or can ask a plurality of carrier waves when more high-quality requires, and in carrier wave low signal-to-noise ratio (common low field intensity district, big multipath delay inequality and heavy interference range are as the edge of macrocellular etc.) situation lower channel time slot takes suitably to reduce signaling speed, distribute wideer time slot or ask a plurality of carrier waves to improve service quality; For the business of low digital rates such as speech, channel time slot can consider to adopt simple and easy Ditital modulation method, and digital signaling speed also can suitably reduce; Kind for Ditital modulation method is too much unsuitable, perhaps just be suitable for for two kinds if any FSK and QAM, otherwise the modulator approach variation effect is not obvious, has increased system complexity on the contrary; The FSK technology is simple and easy, be fit to reduce its technical complexity to the less demanding signaling channel of data code rate with based on the travelling carriage of medium code rate business such as Speech Communication, suitably the reduction data signaling speed signal to noise ratio that can improve channel is worked system better simultaneously; Efficient and the technical sophistication of QAM is fit to business that the data code rate is had relatively high expectations, as video telephone etc., and should be according to one of Ditital modulation methods such as Dynamic Selection 16QAM such as carrier signal to noise ratio, 32QAM, 64QAM.Distinguish that for the wireless channel transmission quality base station should begin to locate the transmitting channel quality in downlink frame periodically and distinguish pattern, feed back to the base station after differentiating by the travelling carriage reception; This quality pattern contains the modulation waveform pattern of the optional network specific digit of different rates and different digital modulator approach, travelling carriage according to the correct degree that receives as differentiating foundation.

The basic structure of the base station of native system, travelling carriage or wireless terminal is similar substantially to existing mobile communication system, but in order to satisfy two-way paging and to receive optional integrated information service etc., even be that travelling carriage increases multimedia functions such as memo pad, dictionary, television reception, Music Appreciation, system terminal need strengthen memory capacity, increase the screen resolution of display and allow keyboard that the ability etc. of non-alphabetic writings such as input Chinese character is arranged, these functions can be with reference to enforcements such as existing Chinese electronic notebook technology, computer technology and multimedia technologies thereof.In order to finish the personal communication task better, it is considered herein that:

1. macrocellular station covering radius is bigger, the path delay of time of each travelling carriage difference up 133 microseconds during as 20 km covering radiuss, just needed to increase the ascending time slot protection zone as not adjusting, therefore need to adopt active measure to be overcome: the step loss condition of travelling carriage ascending time slot is fed back at the macrocellular station at any time, and reach synchronous the zero hour of being adjusted ascending time slot by travelling carriage; Because the satellite station covering radius is very big, each travelling carriage has hundreds of kms to thousands of kms to the maximum path difference of satellite station, more need consider the stationary problem of ascending time slot, (can be with the time slot protection zone of obtaining a less expensive by the relative speed of service of satellite station, optimizations such as the maximal rate decision of fast moving thing): carrier wave of mark is answered by satellite station, this carrier wave leaves enough up signalling time slots (this time slot will influence the value in frame period) or whole allocation of carriers is given signaling channel, allow travelling carriage not disturb other channel to insert satellite channel, satellite station also needs at any time the step loss condition of the up channel time slot of each travelling carriage is fed back to travelling carriage in whole communicating to connect, and is adjusted to synchronously by travelling carriage; Perhaps, satellite station is a high-speed mobile with respect to ground simultaneously, in order steadily to switch to another satellite station channel, travelling carriage should show the network number of the satellite circuit of original networking when inserting another satellite station, doing if this satellite station still supports needn't handover, and this scheme can be used for also certainly that honeycomb switches but perhaps travelling carriage will do the consideration that channel is worth.

2. the partial circuit operating frequency of the frequency synthesizer of system's travelling carriage is generally very high, power consumption is bigger during work, generally there are tens milliamperes, it is travelling carriage main power consumption part when waiting for, therefore the frequency synthesizer energy fast start-up that needs travelling carriage, reach the frequency lock precision fast, its lock-up cycle should be controlled at Millisecond, could guarantee when adopting the Wideband Wireless Digital Communication technology, to accomplish the extremely low power of on average waiting for like this, even the reception local oscillator of travelling carriage has big frequency deviation also can meet the demands simultaneously, as at 900 megahertz working frequency range, 500 kilo hertzs of carrier frequency separations, during 400 kilo hertzs of carrier frequency bandwidth, maximum frequency deviation can allow ± and 50 kilo hertzs, this point successfully brings benefit for the fast frequency synthesizer designs.The travelling carriage signaling, if Personal Communications Services and optional personal synthetic information can adopt secret transmission measure when intermediate nodes such as omnidistance digitlization channel and base station needn't be discerned again, as the signaling that networks, personal information, radio call, the speech channel that fax and digital circuit provide, video telephone etc., at first ownership office or optional information centre need adopt the secret transmission of secret key of a travelling carriage, information can only be moved platform or ownership office or optionally information centre's identification like this, or ownership office deciphering exchange, when belonging to one by one people office together, two travelling carriages can adopt following secret transmission formula: travelling carriage encryption-Channel Transmission-exchange-ownership office of deciphering-ownership office of ownership office encryption-Channel Transmission-another travelling carriage deciphering, in addition, travelling carriage and travelling carriage also can be arranged the encryption key pair secure communication, and plain code information can only be discerned by the mobile stations communicating both sides like this; To non-omnidistance digitlization channel, can produce an accidental enciphering sign indicating number (this sign indicating number can by individual office produce and in signaling channel encrypted transmission give travelling carriage, or travelling carriage produces and in signaling channel encrypted transmission give individual office) in communication line, be transferred to the base station by individual office with channel associated signalling (as the dual-tone multifrequency signaling of speech channel etc.) plain code, make information in radio communication channel by travelling carriage and base station encrypted transmission.

Individual office of system can be formed by existing digital program controlled exchange (or machine) software upgrading of terrestrial network, certainly also can be brand-new digital program controlled exchange and the integrated information service machine of individual office design for the optimum performance that realizes system, but can make individual office invest province by software upgrading, and the digital program controlled exchange of existing part (or machine) can have been supported the contour digital rate business of video telephone, upgrading these exchanges of back (or machine) can satisfy the demand of following Personal Communications Services, even existing digital program controlled telephone call office (or machine) can only supporting telephone etc. the less demanding business of digital rate, also can satisfy general user's simple demand after the upgrading; Existing digital program controlled exchange (or machine) mainly comprises user mobility (as the diverting call phone), user's mobile authentication, charging etc. to the software upgrading of individual office, existing software part possesses, and makes a small amount of specific aim and revises the requirement that just can satisfy individual office substantially; Belong to certain base station or signaling channel or communication channel or wireless signaling channel or radio communication channel individual innings or that belong to other, no matter they adopt which type of mobile communication technology (as wireless communication technology, replace mode, network access mode or channel selection scheme etc.), individual office all needn't participate in, and it is general only to need signaling channel and communication channel be understood as that a common fixing signaling channel and a common fixing communication channel provide service to get final product for the ownership travelling carriage on the terrestrial network; Because the exchange capacity of existing switch generally exceeds the actual demand capacity, as 10,000 clog-free digital program controlled telephone exchanges in software upgrading, perhaps can continue to support several thousand fixing (telephone) users after suitably increasing the memory capacity of switch and suitably adding some trunks and increase to support several ten thousand to tens0000 to move (phone) user (as supporting the video telephone business after the upgrading, then the number of users of this switch support should suitably reduce), therefore system is starting and be not necessary at once newly-built individual office in significant period of time, but the suitable existing digital program controlled exchange of software upgrading part is individual office and acquires several base stations as required and provide channel services for system's travelling carriage of activity in the local exchange area of coverage or bigger zone; Because the above-mentioned individual existing mobile subscriber of office has fixed-line subscriber again, and the optional integrated information service that provides of system, therefore along with the enforcement of system, no matter economically still all there is a strong possibility on function replaces existing subscriber phone office as the individual office of user end office (EO), existing cellular mobile telephone office, existing cluster containerized exchange, existing paging center, even the satellite exchange of following simple employing satellite communication mode, and users may more be ready to become mobile subscriber or wireless user, make that wire user can be fewer and feweri, though reduced urban construction so in a large number, the workload of China Democratic National Construction Association or network operator's laying and maintain communications cable, be of value to beautify the environment with keep communicating by letter unimpeded, but when military conflict takes place, because enemy's strong radio interference, cause the collapse of our Radio Communication, therefore the network operator should advise that important department takes the part wire communication terminal and resemble the wired secure personal communication node of reasonable reserved part the department such as fire-fighting, comes the collapse situation of the radio communication that the strain accident causes; Universal day by day along with personal communication set up the advanced stage that earth satellite communication network that the whole world covers must become PCS Personal Communications System; Therefore the present invention compares with existing mobile communication system, and investment greatly reduces, and network and management also seem simple, and system can develop according to demand by easy stages.

The enforcement of native system can be divided into three phases.Phase I, the person paging system stage, continued to use existing technical foundation with the paging system of Da Qu system covering frequently, constitute Da Qu system or honeycomb system (common-frequency time division or alien frequencies, finger common-frequency time division honeycomb system of the present invention) two-way paging net, the person paging system have (strange land directly or by terrestrial network indirectly interconnection or independently) person paging center, transmitting base station, reception base station (or be merged into transmitting-/ receiving stations with transmitting base station), travelling carriage (or person paging machine); Wherein the person paging center provides two-way person paging business and information service, at first the paging content being delivered to ownership transmitting base station or (person paging center, strange land is sent again) strange land transmitting base station that travelling carriage indicates respectively initiates paging and rationally opens each transmitting base station transmitter according to transmitting base station networking or position etc. to release news; Receive the base station and can adopt the up signaling of co-frequency cell system receiving mobile emission, perhaps, so up signaling is received by a plurality of base stations, but system can handle at paging center, and notifies travelling carriage with the successful up signaling that receives in down channel; In order to finish the person paging business, travelling carriage is compared with existing beep-pager except that increasing transmitter, also need increase basic functions such as literal input and demonstration; A pair of working channel can be adopted in transmitting base station and reception base station, and they can adopt wired mode or another that frequency is interrupted the time-division to the channel at person paging center, or pass-through mode; The baud rate of person paging system and channel size are compared with existing paging system can higher and broad, and baud rate was selected 9600bit/s etc. when baud rate selected 4800bit/s or channel spacing to be 50kHz when being 25kHz as channel spacing; In addition, business such as stock, finance, futures are acted on behalf of as the available two-way paging of the approval that obtains relevant department in the person paging center, and beep-pager adopts initiatively signaling realization automatic roaming of district more.Second stage, the enforcement of zone PCS Personal Communications System, the existing digital SPC exchange of exploitation (or office) PCS Personal Communications System software, main website, substation and travelling carriage, the preliminary partial service that realizes personal communication is as general service and part integrated information services such as speech, Computer Data Communication, person pagings; But above-mentioned person paging system descending Channel Technology standard can be used for the auxiliary wireless signaling carrier signaling machine of main website, and continues to support existing person paging machine.Phase III, development satellite personal communication network constitutes and improves following PCS Personal Communications System.

The present invention is owing to adopt satellite station to guarantee that the whole world covers, the macrocellular main website guarantees that regional covering, picocell station and Pico cell station provide very high communication channel density, have solved the covering problem and the capacity problem of following PCS Personal Communications System effectively; The base station generally need not concrete management, and which kind of wireless channel travelling carriage occupies and generally also need not system intervention, under the situation that the wireless channel of rationally arranging satellite, macrocellular, microcellulor and Pico cell is worth by the channel of the suitable minimum value of mobile station in selecting; The operating frequency that accounts for macrocellular substation, picocell station and the Pico cell station of system base-station absolute majority need not planning, and simple, the reduced investment of putting into operation, can be set up by how tame operator or user; But existing digital program controlled exchange software upgrading becomes individual office, and technology and uncomplicated, and investment also economizes very much; In the communication aspects of handling accident, special case and particular location, system also can easily reach a standard; System need not to adopt very complicated radio digital communication technology, can reduce system cost like this, and that also can reduce simultaneously travelling carriage on average waits for power, average transmit power, and optional integrated information service can also be provided; Therefore native system is compared with existing mobile communication system and is had marked improvement.
