CN1313018A - Channelization and encoding for text information services transmitted via radiocommunication system - Google Patents

Abstract

The present invention sets forth techniques for channelizing and encoding various broadcast information services using, for example, a broadcast control channel to provide information to a mobile station user. The mobile station may be a receive-only device, similar to a simple pager, or may be a receive/transmit device, such as a mobile phone. In order to limit the capacity of the broadcast channel that is consumed by, e.g., a Security Quote service, an efficient encoding and channelization method is provided. The method includes separating the short-message-service broadcast control channel into 3 logical sub-channels: a Security Name channel, a Start Value channel and a Delta channel. These channels provide different aspects of the securities information to the mobile station. By varying the bandwidth allocation of these individual channels, the present invention is capable of providing a very large amount of securities while also maintaining a fast cycle time.

Radio communications system sends the channelizing and the coding of text information services

Related application

The application relates to and has adopted the U.S. Provisional Patent Application No.60/088 of the proposition in 10 days June in 1998 of Alex K.Raith, 845 " the big bandwidth text information services of radio communications system " (" High Bandwidth Text Information Services for Radiocommunication Systems ") and the still U.S. Provisional Patent Application No.60/089 in the 15 days June in 1998 of Alex K.Raith, 280 " headline hyperlink broadcast servies " (" Headline Hyperlink Broadcast Service ").These two provisional application are disclosed to be listed as for referencial use quoting here.

Background of invention

The present invention relates in radio communications system, provide the information service service, specifically, relate to the data by air interface broadcasting encoded and channelizing, with in conjunction with existing radio communication service and system high efficiency rate the broadcast information services service is provided.

These are over 15 years, and the development of civil radio communication is surprising.Particularly beep-pager and cellular telephone are especially outstanding as the commonplace equipment in many urban environments.These two kinds of dissimilar communication devices develop formation with back-up system gradually according to different basic purposes, beep-pager is for one or more terminal uses provide unidirectional limited information traditionally, and cell phone provides two-way voice communications services traditionally.

As time goes on and development of technology, the line of demarcation of the traditional function between these two kinds of dissimilar radio communication equipments has thickened.Some functions that provided by cell phone traditionally have been provided beep-pager, and vice versa.For example, two-way beep-pager develops, and allows the pager carrier message can be sent to paging system, is given to other each side again.Similar, cell phone has been sent and received can be in the ability of the weak point that shows on the display screen of cellular telephone (for example being about 160 alphanumeric characters) text message.This progress on radio communication equipment has caused the exploitation and the operation of a large amount of new information services.

For example, realized some paging systems, be used for providing broadcast information services, for example the stock tickers business to the user of the beep-pager that has the band display screen in a large number.These beep-pagers periodically receive by air interface and for example arrange to buy and sell the related information of power, forward contract or the like with stock or other financial instruments in a large number, show the current price of these bills, make the user can follow the tracks of his portfolio situation.

The user that can expect cellular telephone can be interesting to the service of the information service and so on that provides support in Cellular Networks.Yet cellular system is different from paging system, always is designed to: (1) has limited bandwidth, and this is that for example FCC has stipulated spectrum limitations to cellular application because each administers organization; And the band-limited major part of (2) defined is used to guarantee point-to-point (for example the connection between cellular telephone and the system, voice connect), have only very that fraction keeps to broadcasting, promptly system is to each cellular point-to-multipoint transmission of working in system.Particularly because these cellular system characteristics of back, the system designer treats the amount of information that sends and the frequency of retransmission of information very modestly on available broadcast channel.Therefore, for the broadcast information services of cellular radio communication system can not be easily directly all users of broadcasting wish that the simplest this method of the information whatsoever that shows realizes on their cellular telephone.

For example, imagine a TDMA cellular radiotelephone system, wherein each radio frequency is divided into a series of time slots, and each time slot contains the burst information from a data source, for example digitally coded part voice conversation.By the related burst in some and different sources is carried out time division multiplexing, make and on each radio frequency, can support a plurality of channels.These time slots are combined into a series of tdma frames in succession with predetermined lasting time.The number of time slot is relevant with the number of the different user that can share this radio channel simultaneously in each tdma frame.If giving a different user, the duration of a tdma frame with each time slot allocation in the tdma frame is exactly each minimum interval between time slot in succession of distributing to same user.

These that distribute to same user time slot in succession are non-conterminous on this radio carrier usually, constitute this user's digital service channel (DTC).As mentioned above, this normally point-to-point resource, and in fact most of tdma system has kept most of this available radio channel as DTC, so that guarantee to have big volume of business.Yet, as following will relatively detailed description the in detail, also disposed some digital control channels (DCCH), be used for transmitting control signal and Overhead, comprise the communication mechanism that is used for being connected to radio communications system and appointment DTC.

In the cellular system of other types, also can find similar resource allocation conditions.For example, in code division multiple access (CDMA) system, specificly connect related data and carry out spread spectrum and carry out channelizing (channelization) with one by utilizing a unique spreading code pair.This spreading code, opposite with frequency and time discriminator or combine with frequency and time discriminator, for receiver provides a kind of mechanism that will issue its data by composite signal that will receive and the spreading code associated extraction of distributing to its Traffic Channel.As tdma system, cdma system also can provide some Broadcast Control Channel or other expense signaling channels by distributing some known spreading codes.Yet also as tdma system, cdma system certainly will be that the broadcast message channel keeps more resources (for example, spreading code and power) for the Dedicated Traffic Channel ratio also.

Therefore, desirable is to develop some can provide broadcast information services in the restriction to existing cellular radio communication system technology and system.Particularly, hope can be designed some broadcast information techniques and system, make they can satisfy the terminal use wish to obtain than relatively large may the needs requirement of data updated more continually, and the nervous broadcast channel resource that practices every conceivable frugality.

Brief summary of the invention

Exemplary embodiments of the present invention provides in high efficiency mode and has utilized broadcast resource, supports the technology of broadcast information services by radio communications system.End user's equipment, for example travelling carriage can be to be similar to the such receive-only equipment of simple beep-pager, also can be the receipts/equipment such as mobile phone.The present invention reduces to minimum by the broadcast resource capacity that provides high efficiency coding and the transmission information channelization need be taken broadcast information services.

According to one of the present invention be illustrative exemplary embodiments, this broadcast information services can be the quotation business that is provided support by a system of deferring to IS-136 with broadcast SMS service ability.The part that keeps for SMS of Broadcast Control Channel can be divided into a plurality of logical sub-channel again in IS-136, be used for transmitting the various piece of the data of supporting that the quotation business is used.Specifically, these typical subchannels can comprise a paper title (Security Name) channel, opening price (Start Value) channel and ups and downs (Delta) channel.

These channels send the different aspect of securities information to travelling carriage.By changing the allocated bandwidth of these a few logical sub-channel, the present invention can provide and a large amount of related information of security, also keeps a refresh rate (circulation timei) fast simultaneously.

Other exemplary embodiments of the present invention provide the technology of the information related with sport score being carried out channelizing and coding, and the broadcast resource by radio communications system transmits expeditiously.The present invention can be generalized to any application that needs to send given ensemble of communication.

Describe in detail

Below explanation is made according to cellular radiotelephone system, but very clear, the present invention is not limited to this environment.In addition, below explanation is to be that background is carried out with the TDMA cellular communication system of deferring to IS-136, but (as mentioned above) those skilled in the art are appreciated that, in other digital communications applications, comprise those according to other standards (for example GSM or PDC) designs utilize CDMA as cut-in method (for example IS-95) with those, can realize the present invention.

Specifically, these exemplary embodiments of the present invention have illustrated technology and the system that broadcast information services is provided, these technology and the system available relatively more nervous broadcast resource in the existing cellular radio communication system that can practice every conceivable frugality.Therefore, these exemplary embodiments will be used in the available broadcast resource of stipulating among the IS-136, specifically broadcast SMS channel (S-BCCH), be illustrated.Below with some ordinary circumstances relevant of explanation with the IS-136 system and with broadcast the relevant concrete condition of SMS channel, and saved other certain situation, in order to avoid make the present invention smudgy on the contrary.Yet, interested reader can and also be people's such as Raith U.S. Patent application No.08/482 referring to people's such as Raith U.S. Patent No. 5,603,081,754, to obtain and system's ordinary circumstance that relates to IS-136 and the relevant respectively supplementary of broadcasting SMS technology concrete condition.Above-mentioned United States Patent (USP) and U.S. Patent application disclosed all classifies reference here as.

Fig. 1 shows the example of a common forward (down link in other words) DCCH, is configured to a series of time slot 1,2 ..., N ..., be included in the time slot in succession 1,2 that sends on the carrier frequency ... in.These DCCH time slots can be defined on the radio channel, and are clear and definite such as IS-136, can for example be included in every n one time slot in a succession of time slot as shown in Figure 1.It can be also can not be the duration of 6.67ms that each DCCH time slot has, and this is the length of a DTC time slot according to the IS-136 standard.

As shown in Figure 1, these DCCH time slots can be organized into super frame (sf), and each superframe comprises that several transmit the logic channel of different kinds of information.Each logic channel in the superframe can be assigned to one or more DCCH time slots.The exemplary down link superframe of among Fig. 1 this comprises three logic channels, that is: one comprises six Broadcast Control Channel of time slot (BCCH) in succession, is used for transmitting Overhead Message; A paging channel (PCH) that comprises a time slot is used for transmitting beep-page message; And an access responsive channels (ARCH) that comprises a time slot, be used for that transfer channel distributes and other message.All the other time slots in this exemplary superframe of Fig. 1 can be used for other logic channels, for example replenish paging channel PCH or other channels.Because the number of travelling carriage is more much bigger than the number of the time slot in the superframe usually, thus each paging time-slot be used for paging several share the travelling carriage of some exclusive feature, for example last the numeral of MIN is identical.

Fig. 2 shows the block diagram of a typical cellular mobile radiotelephone system, comprising an exemplary base station 110 and travelling carriage 120.The base station comprises control and processing unit 130, and it is connected to the MSC 140 that is connected with the PSTN (not shown).The ordinary circumstance of such cellular radiotelephone system is all known in this technical field, U.S. Patent No. 5 as people such as Wejke, 175,867 " neighbour in the cellular communication system assists to switch " (" Neighbor-Assisted Handoff in a Cellular Communication System ") and the U.S. Patent application No.07/967 that proposed on October 27th, 1992,027 " multimode signal processing " (" Multi-mode Signal Processing "), these two all are listed as the reference of making the application.

A plurality of voice channels are handled by the voice channel transceiver 150 of controlled and processing unit 130 controls in base station 110.In addition, each base station comprises the control channel transceiver 160 that can handle more than one control channel.160 controlled and processing unit 130 controls of control channel transceiver.The control channel of control channel transceiver 160 by base station or sub-district is to the travelling carriage broadcast control information that is locked on this control channel.Very clear, transceiver 150 and 160 can be used as individual equipment and realizes, resembles voice and control transceiver 170, uses under the situation of DCCH and the shared same radio carrier frequency of DTC.

Its voice of travelling carriage 120 usefulness and control channel transceiver 170 are received in the information of broadcasting on the control channel.Then, processing unit 175 estimates the control channel information of the characteristic of the candidate cell that will lock onto comprising travelling carriage that receives, and which sub-district the decision travelling carriage should lock onto on.Useful is, the control channel information that receives not only comprises the absolute information of relevant its associated sub-district, but also contain relevant relative information in other contiguous sub-districts of the associated sub-district of this control channel, U.S. Patent No. 5 as people such as Raith, 353,332 " communication control method in the radio telephone system and equipment " (" Methodand Apparatus for Communication Control in a RadiotelephoneSystem ") are disclosed, and these patent row are done the application's reference.

Travelling carriage 120 also comprises an input equipment 185 such as numeric keypad, make the user can with the travelling carriage reciprocation.Display unit 190 such as lcd screen is arranged, the visual display of information is provided for the user.Travelling carriage also comprises memory 180.

In exemplary embodiments of the present invention, the broadcast message of transmission is organized into a series of dissimilar logical frame in succession from the base station to the travelling carriage.Fig. 3 illustration the frame structure of a forward of deferring to IS-136 (base station is to travelling carriage) DCCH, show two special superframes (HF) in succession, each special superframe preferably comprises a main super frame (sf) and one superframe separately.Be appreciated that a special superframe can certainly comprise plural superframe.

In Fig. 3 illustration three superframes in succession, each superframe comprises a plurality of time slots, these time slots are organized into logic channel F-BCCH, E-BCCH, S-BCCH and SPACH, these logic channels are below also than describing in more detail., only it is also noted that a forward DCCH comprises a complete F-BCCH information sets (that is, one group of layer 3 message) here, can use manyly to satisfying required time slot that and each superframe all begins with a F-BCCH time slot.Behind the F-BCCH time slot, all the other time slots in each superframe comprise one or more (the perhaps not having) time slot that is used for E-BCCH, S-BCCH and SPACH logic channel.

Referring to Fig. 3, in particular be Fig. 4, each superframe of down link (forward) DCCH is preferable to be to comprise a BCCH channel of broadcast control and a short message service/paging/access channel SPACH.BCCH comprises a fast B CCH (F-BCCH shown in Fig. 3); An expansion BCCH (E-BCCH); And a short message service BCCH (S-BCCH), some of them are commonly used to transmit the general information of issuing the relevant system of travelling carriage from the base station.

The F-BCCH logic channel is loaded with the system information that strict demand is arranged in time, for example the structure of DCCH, essential other parameters and the E-BCCH change of connecting system indicate, this is at U.S. Patent application No.08/482, more detailed explanation is arranged in 754, this patent application and the application transfer the possession of jointly, are listed as for referencial use quoting here.As mentioned above, in each superframe, send a complete F-BCCH information sets.The E-BCCH logic channel carrying time is gone up the strict like that system information of information that requires not as sending on F-BCCH; A complete E-BCCH information sets (i.e. one group of layer 3 message) can be across several superframes, and first E-BCCH time slot that needn't be aligned at a superframe begins.The S-HCCH logic channel carries some short broadcast, for example interested other information of stock information, advertisement and all kinds of mobile subscriber.According to exemplary embodiments of the present invention, this logic channel can be used for support information business, for example quotation business or sport information business.Typical quotation business

Determining how to utilize expeditiously existing broadcast resource to support one for example in the new information service of quotation business, first the frequency that need importantly to determine type, the amount of information that relates to and the informational needs of the information of broadcasting to retransmit.For example, the securities information that sends as the part of broadcasting quotation business preferably includes the value to increase of baseline valency or minimizing of security mark or paper title, the baseline settlement price (be the closing price of the previous day) related with each mark and expression this preset time.According to the length and the figure place that is used for representing its corresponding value of security mark, the eight bit groups that each entry need send can be up to 20.In each character 8 bit, total bit number is approximately 160 bits.By transformat being added some simple restrictions, for example do not send space character, required data volume can reduce few several eight bit groups.Yet such format requirement may have some undesirable restrictions, for example requires the stock mark can not be with the end of digit.These restrictions may be not and current or stock flag transmission format compatible in the future.

Transformat is carried out the data volume that restriction can reduce needs transmission; Yet such system will need to send relatively large data for each security mark.In exemplary embodiments of the present invention, the S-BCCH logic channel comprises at least three logical sub-channel of supporting this broadcast information services: the paper title channel, and opening price channel, and ups and downs channel, as shown in Figure 5.The personnel that are familiar with this technical field are appreciated that the S-BCCH logic channel can be divided into the logical sub-channel more than three, and this does not deviate from the spirit and scope of the present invention, and can infer that other SMS activities in fact can be by different logical sub-channel supports.For example, the U.S. Patent application No.08/482 for referencial use as top row, 754 disclosed like that, S-BCCH can be divided into the individual subchannel of n (for example being 32), supports different broadcasting services, business-level etc.Any one subchannel (as shown in Figure 6) in these subchannels or an above subchannel in these subchannels can logically be subdivided into again and be included in these three subchannels of explanation here.

The paper title subchannel can comprise makes travelling carriage a mark that receives (for example sending) can be mapped as the information of a paper title on opening price or ups and downs channel, so that show the paper title that is more readily understood at travelling carriage.This map information can read from the paper title subchannel, is stored in the travelling carriage so that use after a while.For example, the paper title subchannel can comprise a code element stream, for example is " ERICY ", succeeded by they corresponding paper titles, for example is " ERICSSON ".Travelling carriage can be stored this mapping.Then, if opening price or ups and downs channel comprise mark " ERICY ", travelling carriage just can go out " ERICSSON " from its memory look-up by this, is presented on the display screen of travelling carriage with current stock valency.

With this map information, the type that the paper title subchannel can also provide the used coding in information service operation side (for example, information type identifier that provides on opening price and/or ups and downs channel and/or information format are seen the typical alternative of the following stated) and an expression travelling carriage whether should read in many bits (for example be 8 bits) the change signs (CF) of all the other information to upgrade its institute's canned data of broadcasting on this subchannel.CF can be the special-purpose system side of operation code (SOC), special-purpose country code or for the code of this both sides' special use, the feature of change sign also can meanwhile send.Travelling carriage can be by using the radio programming Control to the explanation of CF, and for example the OATS in IS-136 perhaps sends in the ups and downs channel.

It is a date value that CF can implement, and need be updated in the information of broadcasting on the paper title channel so that determine whether.The date of utilizing CF to provide, the lastest imformation repeatedly that travelling carriage mobile between some inharmonic professional sides of operationing just needn't be provided by difference operation side.If CF represents one than the nearer date with storage, travelling carriage is as long as change its storage data.

As mentioned above, the content of paper title channel mainly comprises mapping and the coded message of formal security mark (often not changing) to the popular or regular name of security.Like this, the change frequency of the information of broadcasting on this channel is extremely low, therefore makes exemplary embodiments of the present invention distribute a smaller bandwidth for transmitting this subchannel.In addition, such allocated bandwidth can change according to for example one day time, and is as described below.

Because the information of broadcasting on the paper title channel should seldom need to upgrade, the therefore little situation that a travelling carriage moves between some inharmonic professional operation sides that is marked with of closing.If the professional Founder of managing is sending a very different security group that sends with another professional operation side, it will only influence other two channels (being ups and downs and opening price channel).If a professional operation side sends the mark that a travelling carriage does not also have the paper title of storage, so travelling carriage just replaces title to show to the user this mark.If do not find to be stored in some titles in the travelling carriage on the paper title channel of another operation side's broadcasting, these titles needn't be removed; And along with moving between business operation side, travelling carriage can be added into some titles the mapping that it is stored.

One just to move to the change of the broadcast message that the travelling carriage of next country experiences from a country more fierce, for example, broadcast information services operation in France can be broadcasted a table of showing the corresponding paper title of some marks and French stock market, may enter Germany receiving these back travelling carriages, what read is the information related with German stock market.According to an exemplary embodiments of the present invention, when in the Overhead of radio communications system broadcasting, detecting a different country code, travelling carriage falls the mark-name map related with first country code from its core dump memory clear, perhaps preferably generates new hereto new one the mark-Business Name table of country code.If travelling carriage produces a new mark-name map, it just can for example be distinguished by travelling carriage and receive old country code when it rotate back into last country, directly is converted back to this old mapping.The national stock mapping situation that in its memory, keeps it when this can travel travelling carriage abroad.In addition, this travelling carriage can be remembered the mark-name map of the country that it is just being visited.

The paper title channel can also provide a classification value.According to the present invention, security can be divided into some classifications such as company (for example telecommunications company), metal, currency again.If occur changing in a kind of security, these security are divided into some sublists again will not needed whole title collection reprogramming with this way of some security types; Yet, divide so again and may need a plurality of CF and type identifier.

As top pointed, travelling carriage can be stored more than one table and related CF.This does not just need the Business Name table of resetting during roaming between some country codes or different business operation side.Certainly, the personnel that are familiar with this technical field be appreciated that desirable be have some in same country or the area that specifically common stock exchange covers by for example in the Vatican and the Italy a plurality of business operation sides are common tables.

The information that needs to transmit in the paper title channel can also otherwise rather than by S-BCCH send.For example, utilize as in IS-136 defined stride the sky activating service, download this information with a honeycomb/PSC/ satellite data business or a site from the Internet, enroll travelling carriage by for example infrared link between portable computer and telephone set.Like this, more mark-the title of new shares may not carried out so soon or automatically, but minimizing is taken the bandwidth of broadcast resource.

As mentioned above, owing to the information that sends on the paper title subchannel needn't often be upgraded, thus be favourable, because this channel can hold the comparison lot of data.When issue will upgrade paper title information is appreciated that more fully under the background of following this example.Suppose that each paper title needs about 10 eight bit groups (i.e. 10 8 bit character), each mark needs 4 eight bit groups.Add some Overhead, for example need 15 eight bit groups, 120 bits in other words, therefore for a set that 1000 kinds of security are arranged, need to send and be 120,000 bits by total bit number that travelling carriage reads.Distribute to the paper title subchannel if suppose 10% of a S-BCCH time slot, will need 120,000/ (0.6*0.1) to upgrade these information about in other words 2 hours circulation timei.Yet the certain hope of user can be upgraded these information quickly.

A kind of scheme is to increase the bandwidth that is used for this channel, promptly transmits the paper title subchannel with the S-BCCH time slot more than 10%.Another kind of scheme is not send this channel between trade date.Can use any available mapping that can obtain (this means travelling carriage can with the mapping pre-programmed between label information and the paper title, so that begin to utilize this business rapidly) at travelling carriage between trade date from memory.Travelling carriage can provide old (storage in advance) title always, reads the paper title channel and upgrade name information after finishing in the day of trade.Perhaps, also can be not to the travelling carriage pre-programmed, and the direct show tags title of travelling carriage if the mark title sends, receives paper title information up to travelling carriage on opening price and/or ups and downs channel.

Second subchannel that illustrates is the opening price channel.The opening price subchannel to the effect that for each mark the day whole settlement price.With whole settlement price of day, the opening price channel also provides date of the type (be form) of professional operation side to the used coding of this channel, security last transaction and this settlement price as the effective date of opening price.The term of validity date is used for preventing travelling carriage (promptly at one section time durations that does not have transaction) stressed opening price channel between stand-down.In an exemplary embodiments of the present invention, the date of last transaction and validity date can merger; Yet for those application (for example, carrying out statistical analysis and application relatively) to the date sensitivity, the actual date of the last day of trade may be useful as the transmission of an independent information unit.

Except above-mentioned information, the opening price channel can also provide table number, sub-table number (if necessary), stock mark (SS) login item number and table login item No..Table login item No. can be for a specific table special use or be common for all tables.Can save transmission table login item No., so that reduce the data volume that needs transmission; Yet,, can help that restore data under the situation of word error is being arranged if this value sends with SS.

The value that rises/fall that the ups and downs channel provides expression to increase or reduce from opening price for each mark.With rising/fall value, the ups and downs channel also provide professional operation side to the type of the used coding of the information that on this channel, provides, constantly, table number and sub-table number.Table number makes professional operation can allow the security classification of user's access with control.For example, the user can only subscribe to the quotation of limited New York Stock Exchange.Similar, owing to utilize sub-table number, certain group in the table that can only allow the user to insert to be sent.For example, can allow the user only to insert the telecommunications company of stepping on NASDAQ.Each interior table entry of table all has a table login item No. of distributing to it.

Many different coding techniquess or form may be used to the ups and downs channel.Because different business operation can be to select different coding techniquess, the therefore information of broadcast beacon coding techniques simultaneously is so that travelling carriage can correctly be explained the information that receives.Some typical coding techniquess to the ups and downs channel are described, but those skilled in the art are appreciated that also and can adopt other technologies that this still within the scope of the present invention here.

For example, can send label information (for example being " ERICY "), be illustrated in a B shareB and each the corresponding situation between the value of rising/fall that on the ups and downs channel, sends significantly at the ups and downs channel.Perhaps, for example, if desirable be to reduce to the bandwidth requirement and/or the raising of ups and downs channel rise/the fall refresh rate of information, can save the mark flag information fully, and the order of the value that rises in such cases/fall is with the mark sign of implicit associations.If adopt a kind of scheme in back, just should some on the ups and downs channel, periodically provide in Overhead of transmission make travelling carriage can it begin to read on the ups and downs channel time started some arbitrarily during information to this information synchronization.

Sending mark value significantly and only relying on that to indicate a kind of half-way house between need these two kinds of selection schemes of mark of transmission be also to send the reference number of an identity marking except the transmission value that rises/fall with sending the related implicit information of value order that rises/fall.For example, if broadcast information services support 65,000 B shareB altogether, so the value that just can rise with each/fall would send a reference number with 16 bits.Reference number can be pre-stored in the travelling carriage and/or can receive with previously described other information on the paper title channel.

These marks that rise/fall send by the ups and downs channel successively from the beginning of table or table sequence.If send the mark reference information not obviously, the content of table can for example be expressed as :+1; 38 ,-11; 18 ,+12; 132, this by mobile station decodes is :+13/8 ,-11 1/8 ,+121/32.Table can also comprise some common Overhead, for example time stamps.This typical format that sends information on the ups and downs channel is based on ups and downs is expressed as an integer and/or a fractional value.On the other hand, if adopt decimal ups and downs, that just can provide decimal representation, perhaps decimal ups and downs can be expressed as the mark of some loss of accuracy that predesignate (for example being 1/8th or 1/32nd).

Most of security are so at American market at least, and it is represented that price changed the one-bit digital (1-9) that is not more than the integer part that can use price indication at any given day.Therefore, this exemplary embodiments of the present invention is represented the integer part of every kind of price of securities with 4 bits.In addition, suppose that each mark quantizes with the increment that is 1/32, makes the fractional part of price indication to send with 5 bits on the ups and downs channel.So, total the bit number that the need of each mark send on the ups and downs channel will be 11, comprise each 1 bit+/-symbol and one indicates whether with additional integer-valued designator (for example for specific security ups and downs greater than 16 dollars time) is arranged.If adopt metric form, just need 7 bits (is centesimal decimal with the expression precision) for fractional part, make total bit of each mark or security rise to 13 bits.

Below to once comparing with the above-mentioned exemplary embodiments of ups and downs channel imagination and the comparatively directly realization that under each situation, all sends all necessary informations that comprise complete paper title, complete security currency etc.For such realization, can imagine that every kind of security need about 100-160 bit, the present invention is used in this explanation can reduce broadcast bandwidth significantly.If not be used in here the channelizing and the coding of explanation, the data that need to send increase ten times possibly, make such business owing to lack enough broadcast channel bandwidth or owing to refresh rate is low as can not to accept (from the user) and be difficult to carry out.

In order further to understand advantage of the present invention, consider following this example.This business can become securities ledger some subclass, for example: domestic, external, futures, commodity, currency, or the like.For the set that 1,000 kinds of security are arranged, send the required bit number of this information (as explained above without the mark reference) by the ups and downs channel and be approximately 1000*11 (first example that provides more than the utilization) 11,000 bits in other words.This number has increase slightly, for example is 15,000 bits to add some expenses (for example time stab information, type of message, subchannel identifier etc.).

The clean bit number of each of S-BCCH layer 2 frame is estimated about 100 bits.Therefore, on the basis of a time slot of each superframe, throughput is 100/0.6 166 bps in other words.So, if each superframe is distributed to the time slot that has only of this business, and suppose that this bandwidth all is used for ups and downs channel (regarding to the discussion that changes bandwidth in time as follows), just need to send in 90 seconds the information (not considering error code) of 1000 kinds of security.If utilize three time slots in each superframe, the refresh cycle just can be reduced to 30 seconds.Certainly, other allocated bandwidth also are fine, also within the scope of the invention.

In order to improve the efficient of this quotation business, the allocated bandwidth of each quotation subchannel can for example the hour, be changed according to the state of securities market.When reopening after a cessation of business transaction, the major part of this bandwidth is distributed to the ups and downs channel.This be since as mentioned above the ups and downs channel be provided at and stock that trading time period constantly changes (promptly the need upgrade) value that rises/fall occurs.On the other hand, to reopening after a cessation of business, the major part of this bandwidth is distributed to the opening price channel again behind close market.The paper title channel will be a channel that bandwidth ratio is less, can only when close market, send, because can imagine and for example often not take place that a stock mark is distributed to another company or the such situation of title is revised by a company, so this channel will not quite need often read.

Table 1-3 summed up of the present invention reopen after a cessation of business and close market during the possible allocated bandwidth situation of some S-BCCH subchannels.In the following description, those skilled in the art are appreciated that the exemplary S-BCCH timeslot number listed should be with regard to literalization, but the effective multiplexed rate of these logical sub-channel in the reflection S-BCCH.Before reopening after a cessation of business, the broadcast bandwidth of distributing to the opening price channel can be 12 or 3 S-BCCH time slots, and is as shown in table 1.The ups and downs channel can not distributed to bandwidth, and the paper title channel can have a smaller bandwidth, and for example 1/2 of a time slot or 1/3.Depend on circulation timei illustrate previously for typical case's coding situation of price indication etc.

The S-BCCH subchannel	The S-BCCH timeslot number	Circulation timei
			Opening price opening price opening price	????1 ????2 ????3	＜7 minutes＜4 minutes 2+ minute

Table 1

Table 2 has been summed up the possible distribution condition of opening price channel during reopening after a cessation of business.Can see that the opening price bandwidth will reduce, can be used for this business so that the ups and downs channel can have most of bandwidth, and the paper title channel can have little bandwidth or zero bandwidth.

The S-BCCH subchannel	The S-BCCH timeslot number	Circulation timei
			Opening price	????1	＜7 minutes

The opening price opening price

????1/2 ????1/3

＜14 minutes＜21 minutes

Table 2

The bandwidth of distributing to any one channel in these channels will depend on that (at least in part) distribute to total broadcast resource of information service.For example, be restricted to 2 S-BCCH time slots if be used for the total bandwidth of quotation business of the present invention, the allocated bandwidth during reopening after a cessation of business can be as shown in table 3.

The S-BCCH subchannel	The S-BCCH timeslot number	Circulation timei
			The ups and downs opening price	1.5 time slot (75%) 0.5 time slot (25%)	1 minute＜14 minutes

Table 3

In the allocative decision of having only very limited bandwidth to use like this, the paper title channel only sends when close market.For new active mobile station, first day with security mark substituted securities title, or with the title (if any) of pre-programmed.

According to the present invention, can provide the quotation business service for the user by different subscription level.For example, basic service can comprise the generally stock of transaction of great majority, and the price raising business can comprise commodity, currency and futures.The quotation business can provide free one or more business service, and is allowing to insert other business on the basis of paying by using.

Insert the business that those need be charged in order to control the user, the present invention has considered these business are encrypted.Like this, a user just needs predetermined decruption key and could insert a specific class of service.

In case the user has granted access, travelling carriage just can be the user at any time and receives and be presented at the business information of broadcasting on the logic channel that illustrates previously through the processor processing of travelling carriage.For example, can on display screen 190, provide following stock information for the user:

ERICY?53?3/8+1/8 MOT?58?5/9+3/7 LU?71?1/8-1/8 NOKA?64?8/9-3/8

T?63?1/2-1?1/4 SBC?71?1/32+3/32 BLS?62?1/16-3/16

As mentioned above, the paper title channel provides necessary mapping, therefore can show Business Name.

????Ericsson?53?3/8+1/8
	????Motorola?58?5/9+3/7 ????Lucent?71?1/8-1/8 ????Nokia?64?8/9-3/8 ????AT?&?T?63?1/2-1?1/4 ????South?W.Bell?71?1/32+3/32 ????Bell?South?62?1/16-3/16

By using a function key, the user can from first to last roll the stock information table that provides on the display screen 190 is provided.For each business-level several tables can be arranged.The present invention also makes the entry in the table that the user can be different with some be organized in some files.For example, one has some security in several tables and the user of several business-levels can put into these security an independently file.This has reduced widely and from first to last rolls the whole table of volume and search the needs of the information that this user is most interested in.

For the ease of data retrieval, business information can be decomposed into some classifications as mentioned above.For example, can with information according to the type of business (for example: telecommunications, oil, bank, or the like), the transaction this mark market (for example: NYSE, NASDAQ, or the like) or the security type (for example: stock, futures, commodity, or the like) classified.These different classifications can be provided with by business operation side, send to the user with data.Obviously, a kind of security can be related with more than one classification (for example telecommunications and NASDAQ).In order to reduce required necessary bandwidth, classification information can be used as one, and all members of classification or the common information unit of a subclass send hereto.Therefore, these tables for example can be organized into that the NYSE class at first sends.In this environment, send telecommunications stock.

In an exemplary embodiments of the present invention, can warning be set for some other security or a complete file folder.For example, some triggers can be arranged to indicate the ups and downs amount of one or more security or total value to surpass a scope above the ups and downs that the relation between specified limits (or scope), two or more security surpasses a scope or whole file.So, because the triggering of one of above definite event, for example can cause making the user watch out for this incident by the warning such as audio signal, icon flicker or vibrator.If the user has been arranged to radio communication equipment receive only in the middle of all tables its particular range (for example power or the current drain in order to reduce the travelling carriage battery) of be fit to receiving and one or more security in this particular range, then triggers of can make this mobile device begin to read in these eligible lists and gather more greatly or more completely.In addition, if a kind of security reach certain degree or exceed a scope, travelling carriage (if it is a two-way travelling carriage) just can be to the notice of another kind of user or equipment SMS message of transmission or another kind of form.This can for example be used for sending an email message to an agent, to sell or to purchase a kind of security.

As seen from the above description, in order to be engaged in the quite attractive quotation business (being the business that a kind of needs provide a large amount of securities datas rapidly) that desired data is provided on S-BCCH, the data volume of every kind of security must be very little.The present invention is separated into three channels with data, controls the allocated bandwidth of these channels according to state of market.For example, in the exemplary embodiments of above explanation, the major part of bandwidth is distributed to the ups and downs channel, this make become in the bandwidth constraints of quotation business of the present invention available DCCH in the radio communications system of deferring to IS-136 of today practicable.

In some countries, may not stipulate the stock mark.The full name or the letter name that change into security identify security.In this case, the opening price channel can comprise a unique identifiers, for example is a numbering, replaces a security mark.So this identifier is used for broadcasting on the paper title channel paper title is linked to the opening price channel,, be linked to the ups and downs channel from the opening price channel again if on the ups and downs channel, adopt mark title or identifier.The identifier title that in fact just serves as a mark.In fact, the formal mark title identifier of a special use just if any.

Benefit with regulation mark rather than unique identifiers is, if not storage and the corresponding paper title of regulation mark of mobile device just can show these regulation marks, but perhaps unique identifiers can not be discerned concerning the user.Therefore, adopt the system of unique identifiers rather than stock mark for those, desirable is to make user's identifiable information to show at an easy rate with the mapping between paper title and the unique identifiers to the remote equipment pre-programmed.

The selection scheme of this transmission paper title channel, if particularly the content delivery rate of paper title channel is identical with ups and downs channel content transfer rate with opening price, be in logic and send full detail (title with common signal channel, opening price, therefore ups and downs) equivalence does not have a benefit of the present invention (for example using a spot of broadcast resource).

If mobile device has a local communications facility, for example infrared or radio link, the data that receive can send to an all-purpose computer, PC for example on knee.It is more easy to analyze data in such equipment, because the common neither one of the modulator-demodulator of travelling carriage is user friendly or the user interface and the application program of feature richness.User's portfolio can reside in the PC.PC can have the program of the information of broadcasting that an analysis transfers by travelling carriage on each subchannel, this program can be User Alarms and/or comprise the assessment that relates to the customer investment collocation according to more senior trigger.

As mentioned above, the ups and downs channel can comprise one with sent provide the related hour designator of the value that rises/fall of the security of information by business operation side.This time designator can reflect the time (the ups and downs value that provides when be effective in this securities market) and/or the transmitting time when the ups and downs channel sends a class value (for example being included in the whole security set in this active set) for the first time of the last transaction related with this value in the ups and downs channel.Professional operation can be reflected in over the specific scheduled time to be defined in these values that send on the ups and downs channel, and for example 20 minutes, some transaction of generation.

The time related with a kind of value of security (according to above-mentioned any technology) can show to the user on the display screen of travelling carriage.Because bit error (or specifically word error), some frames (for example, the layer 2 S-BCCH frame in the illustrated in the above environment of typically deferring to the IS-136 system) will not recover.If the refresh rate of the content of ups and downs channel is identical with the circulation timei of channel, the information of losing just can not occur again.Therefore, travelling carriage can have the more currency information of other security that is compared to for some security.Even rise/and to fall data on the ups and downs channel, to retransmit, the data that can not assure the specific security of losing last time are exactly scrutable for the second time.Therefore, some security can utilize according to being that the value that the old ups and downs value of preceding several cycles calculates is shown.

According to exemplary embodiments of the present invention, the stock price of demonstration and/or time designator can provide a special-purpose indication, point out to the user when it refreshes with the information of the ups and downs channel that receives.For example, can point out the relative time that price has refreshed by color and/or the brightness of adjusting the value that shows with a designator that fades out by the time.Perhaps, can on display screen, provide an icon, point out the recent renewal of this price, perhaps opposite, be older.This indication can be through seconds or tens of seconds, and perhaps with in this system the refresh rate of the refresh rate ups and downs amount in other words renewal of transmission circulation duration is relevant relatively, fades away.

Information updating indication how long should depend on the refresh rate to broadcast data of the professional side of operationing, rather than send the circulation timei of a complete information sets, if these two speed are differences.For example, if be one minute (promptly per minute sends a complete information sets on the ups and downs channel) circulation timei of transmission, and this business is per 5 minutes renewal primary informations, and the value that therefore rises/fall before business operation side upgrades will be retransmitted five times.In this case, the time designator of the information that is showing should warn just whether the shown value of user is can obtain from business operation side recently, rather than travelling carriage whether can be exactly to the circulation decoding of the nearest repetition of ups and downs channel, if it had received the decode same information in last ups and downs channel circulation.By exchange hour being provided in broadcast channel or using the change designator, mobile device just can be identified in the difference between the information of the content of renewal in the ups and downs channel and repeating transmission.

Content refresh rate and the difference between circulation timei also provide some to adjust the chance that travelling carriage reads ups and downs channel mode.For example, be example with IS-136, the minimum segment data that can accept or refuse is layer 3 message.Layer 3 message can comprise the data up to 255 eight bit groups.Need transmit a total length message with several layer 2 frame.If the word of a layer 2 is not recoverable, whole message just can not be given higher layer.Can there be a kind of mechanism (for example numbering) to make travelling carriage read layer 2 frame of losing by retry, if this information repeating transmission, and would not do not require that other layer 2 frame are recoverable.

Because these class data that send by broadcast information services according to the present invention change ratio such as the other system broadcast message is more frequent, therefore message-length is designed to such an extent that not need too many layer 2 frame to send be suitable.For given frame error probability, so just improved the possibility of the message that in attempting for the first time, just regains one's integrity.If lose a message, in the ups and downs channel, will lose several entries usually.Usually, need several layer 3 message to transmit the whole circulation of this ups and downs channel.The length by reducing these message and the number of corresponding increase message just can recover more data for each circulation travelling carriage in a circulation.If the content refresh time ratio is long circulation timei, travelling carriage just can concentrate in subsequently some transmit and recover the message of losing in previous circulation.

Broadcast channel for example as the part of ups and downs channel, can be given in the number of repetition in the circulation of content refresh and the sequence number of current circulation.Use last example, system can the broadcasted content refresh cycle be five broadcast cycle, and this is second circulation in five broadcast cycle.This reads the information of repeating transmission when travelling carriage can only be correctly decoded in previous circulation, perhaps only read information when a new content refresh circulates beginning, thereby make travelling carriage can prolong its battery life.

Because the content of ups and downs channel is combined into some message, the part that time stamp (as the transmission or the transaction time stamp of explanation earlier) can be used as message sends rather than sends with the every entry in the ups and downs channel.Expense that provides the time stamp data required has been provided for this.Similar, any is that common other types information can send once in this message for some contained in the message of a special use specific ups and downs channel entries.For other two channel types, common attribute is suitable for being bundled in layer 3 message equally.This binding can also be used for any other layer or segmented mode that total agreement is found.

For example, as described above, broadcast channel can be divided into some subchannels again.Several message can send in a subchannel.Therefore, can be according to three channel types that this exemplary embodiments of the present invention proposed for example with single subchannel carrying.Bundle common expense and be preferably on the highest common point and carry out, so that reduce for the required bandwidth of these attributes.One for example is indicated in information that concrete business on the broadcast channel, circulation timei, circulation repeat the key property of sequence number, table number, can retransmits information of data deciphering or the like and repeatedly be not limited to minimum time quantum, promptly in circulation whenever the highest common ground not only send once.If travelling carriage can not read this information, according to the specifying information type, it may not be synchronous to information flow, must wait for next time occurring.Therefore, as all broadcasting services, have at bandwidth efficiency and between the time to the mobile station login of up-to-date arrival one compromise.The sport information business

Another example that the suitable sub-channelizing that proposes according to the present invention carries out the broadcast information services of high-efficiency transfer is a sports news.For example also can in a radio channel, send expeditiously with the sport information shown in the textual form in the banner headline in the CNN headline news.

This channel is called the physical culture business of applying mechanically (Canned SportsService) CSS here, can send with broadcasting and point-to-point two kinds of patterns.Ad hoc mode is an addressing message (or message set) that sends on FACCH or SACCH channel.This business also can utilize a Packet Data Channel to insert from a server.For ad hoc mode, travelling carriage can send a request to a specific sports results, and perhaps travelling carriage can particularly during league matches is carried out, receive sports results automatically periodically on the same day.At broadcast mode, do not need system to insert.

An example of the information that CSS can show is:

The New York Rangers team-2-0 of Pittsburgh team

Miami team-the 1-4 of Detroit team

First row contains 34 eight bit groups.Second row is the example that team's name contains fewer character.Second row needs 20 characters.These eight required bit groups comprise not " newline " and all space characters between title of character display.This demonstration needs 54 characters.In addition average for above these two results, each result needs 27 eight bit groups, i.e. 8*27=216 bit.The existing text based SMS business of finding in most of radio systems (for example IS-136) can be used for sending this information.Professional as above-mentioned quotation, the purpose of this exemplary embodiments of the present invention is will significantly reduce to send the required bit number of this category information.

In the U.S. and Canada, the exercise group that obtains most of people's concerns is made into just a few league matches.Main league matches has NHL (ice hockey), NBA (basketball), MLB (baseball), NFL (football) or the like.These characteristics of sport information structure help the sport information sub-channelizing is carried out radio broadcasting, and situation is as follows.

In first exemplary CSS realized, the league matches of paying close attention to some extent for institute was all specified a league matches identifier (LI) and is that all teams in a league matches all specify a league matches member identifier (LMI).Therefore, the combination of LI and LMI has just identified a team and sports genre uniquely.Suppose 32 teams are arranged at most in a league matches.Therefore the bit number required for LMI be 5 bits.Suppose that an one-bit digital is enough to ecbatic (i.e. 4 bits).Space character, dash or the like do not need to send.Required total bit number is a 5+5+4+4=18 bit.Under the situation of the protocol overhead bit of not considering to send, this and the text based that needs 216 bits can be transmitted example more once.

This exemplary format that is used for CSS is very high efficiency, but flexibly little.For many motions, for example football is not enough to the result with a numeral.The number of team may be greater than 32.Therefore, this form may comprise a continuation sign of pointing out whether then to also have numeral, perhaps utilizes a length mark to illustrate each numeric results with how many bits is represented.Those skilled in the art are appreciated that the specific length sign and continue sign that this is known in this technical field, be used for correctly reading the required information of broadcast message for receiver provides, and for example see IS-136.A kind of agreement flexibly will need a little bit for each result more.Yet, efficient still than free-format based on the height of text transmission 10 times.

According to another exemplary embodiments of the present invention, contain two channels for the used agreement of CSS:

1.CSS programming channel (CSS-PC), and

2.CSS channel (CSS-RC) CSS-PC channel contains as a result:

The CSS-PC identifier

League matches identifier (L1)

A series of entries

League matches member identifier (LMI) set

Team's name

As the paper title channel, CSS-PC can send in the not extremely busy time of the broadcast channel in a day (for example at night) usually.The content of CSS-PC also can be by travelling carriage manufactory prepackage, send to travelling carriage or utilize local communication (cable for example as the part of empty more activation or program event (for example when a telephone number is distributed to a travelling carriage), infrared, short radio link business or the like) be stored in this equipment.CSS-PC links a title (for example New York Rangers team) and an identifier (for example number), and this mapping situation can be stored in the travelling carriage.So this identifier is used for representing corresponding team by CSS-RC.Equipment becomes maps identifiers the team's name that shows to the user.The CSS-RC channel contains:

The CSS-RC identifier

LI(1)

The login item number

As a result 1, as a result 2 ..., n as a result ..., m as a result

LI(2)

The login item number

As a result 1, as a result 2 ..., n as a result ..., p as a result

Wherein each " n as a result " contains 2 LMI and score.Length indicator, continuation sign etc. are not shown above and can append to each " n as a result " entry so that agreement can similar flexibly expense on displaying contents.

According to another typical C SS embodiment, league matches identifier (LI) replaces for general team's identifier (TI) set of all league matches with one.For example, can respectively specify an identifier (for example number) for the U.S. and Canadian those big cities like this.For 1000 cities, need represent all cities with 10 bits.

TI imagination than LMI superior be not need reprogramming when entering or withdrawing from a league matches in some teams.According to the length of these TI and LMI, required bandwidth (bit number of transmission) also can be different.Because the major part of required bandwidth is used rather than the league matches identifier by these results, and these league matches can be learnt from their abbreviation (for example NBA), so these league matches identifiers can directly send as text and can obviously not sacrifice bandwidth efficiency.Therefore, if can offer an explanation abundant city, the TI imagination can not need a programming channel fully.Therefore any sports results between city X and Y can show in the mode of bandwidth-efficient rate utilization.Have only sports genre to send, perhaps can use the combination of LI and text with a uncoded text formatting.

A benefit of LMI imagination is that what to show is full name of team rather than city just, and that for example show is New York Rangers team rather than New York.If there are two teams related with same city in a league matches, for example New York Yankees team and New York Mets team another difficulty will occur with the TI imagination.

For this second exemplary embodiments, so channel can comprise as a result:

The CSS-RC identifier,

Geographic area (for example U.S./Canada)

The text of first group of result (for example NBA) is described

The login item number

As a result 1, as a result 2 ..., n as a result ..., m as a result

Second group of result's text is described

The login item number

As a result 1, the result ..., n as a result ..., p as a result

As a result in the channel, utilize (applying mechanically) form of predesignating can send other supplementary at the CSS that adopts the form of stipulating above any.Message (cannedmessage) is applied mechanically in utilization, can make bandwidth requirement lower.Some examples are shown below.

Supplementary in CSS-RC can be some designators, for example provides:

Final result

Have a rest between

N quarter (N=1,2,3,4)

Cancellation

Postpone

In addition, also can send the text of implantation, particularly use when message is not suitable for illustrating the situation of concrete match any applying mechanically.Auxiliary sleeve information and as follows with an example implanting text:

Miami team-the 1-4 of Detroit team final result Detroit team enters play-off

Speech " final result " is one and applies mechanically message (need just a little bit transmission, these bits are mapped to the one group of message that is stored in the travelling carriage, cause showing speech " final result "), and the text of italic is the text of implanting.The frequent more text that can be used as implantation of specific idiom sends, and this idiom is long more, considers with the meaning of applying mechanically solution just big more.For example, Detroit team enters play-off and can apply mechanically message set and applied mechanically by Detroit will " be entered play-off " and include in LMI or TI sign.

In the 3rd CSS typical case realizes, before starting the clock, these teams are matched.Any technology described above can be used for clear and definite these teams to (LMI, TI or text).Before starting the clock, the less bandwidth of distribution ratio for this reason is because it is not urgent in time that travelling carriage is matched programming.Pair of L MI or TI distribute a team to sequence number (PN).For example, the match between New York Yankees team and the Baltimore Orioles team can be appointed as PN=1, and PN=2. is appointed as in the match between Boston Red Sox team and the California Angels team.So travelling carriage can be stored this information.

When starting the clock, just send PN and result.For example transmit 1,2,1 and can be shown as " 2 Baltimore Orioles teams 1 of New York Yankees team " by the travelling carriage explanation.Perhaps, can send the result according to the order of PN.Therefore, what must send has only score, and this has further reduced required bandwidth.This exemplary embodiments requires travelling carriage just to have unpaired message before explaining score information.Therefore, unpaired message can send on an independent subchannels of separating with the score channel, and this subchannel only need read once every day.In this pairing embodiment, also can use assistance information transmission as explained above.Other typical cases use

The present invention also can for example be used to provide the service of broadcasting weather service.Weather information for example with on the independent programming of those of separating that are shown in Fig. 5-7 channels is being broadcasted, and marks the area related with weather information (for example city, small towns).The programming channel can have different contents in the zones of different of a country.Meteorological type also can mark in advance, promptly is defined as and applies mechanically message.Applying mechanically not that message is fit to or the message of needs exceeds availablely when applying mechanically information, this meteorological application also can send the implantation text, situation and top to the sport score application note much at one.

Broadcasting weather information example can as:

The probability that rains is 60% Apple Hill revelry cancellation

The Wake county from afternoon 8:30 thunderstorm rain is arranged

In above-mentioned example, each has the text chunk of underscore to can be used as one to apply mechanically message and provide, and promptly recovers this message from the memory of remote terminal again and is shown by send an identifier on the meteorological brodcast subchannel." Wake county " text can be a local programming message, promptly has only certain travelling carriage subclass can make this message stores in their memory.The text of italic can be implantation message, i.e. a message of broadcasting as text.Other text chunks are general, and they can be the parts for the common programming message of All Countries.Therefore, clear and definite message and can have several subchannels that dissimilar business/bandwidth applications is provided to the programming channel of the link of a short identifier.It is contemplated that with the programming channel with a country this locality, the area.

It seems isolatedly, the combination of the refresh rate of amount of text and required weather information perhaps be not resemble for example send the stock tickers heavy.Therefore, the broadcasting weather service is used and can be used direct text formatting, and all desired information is directly broadcasted on a broadcast sub-channels.Yet when being used in combination with other broadcast information services, it also is rational developing a channelizing form that is used for weather information.If developed the channelizing agreement for other broadcasted application, complexity does not increase or only increases few channelizing method processing weather information that illustrates previously of just also can utilizing for remote equipment.

Another kind of potential may the using of channelizing of the present invention and coding techniques is the Broadcast Journalism business.It is not quite suitable that this category information is applied mechanically message compared with some other exemplary embodiments of explanation here, therefore little this class layering channel architecture that is fit to.Yet, have some keywords and be suitable in the broadcast message news, applying mechanically expression, for example president, Congress, Senate ..., check and approve, refuse, propose, elect, defeat, lawsuit or the like.In this case, channelizing news method also can be in conjunction with for example one or more professional employing such as channelizing quotation business, channelizing sport information business, channelizing weather service.Perhaps, news can be used as a kind of broadcasting headline hyperlink business and provides, as Alex K.Raith illustrated among the common unsettled U.S. Patent application No._ " headline hyperlink broadcast servie and system " (" A Headline Hyperlink BroadcastService and System ") that proposes same date with the application, this patent application is listed as for referencial use here.

It is the broadcasting service of Airport information that another typical case of technology of the present invention uses.The example of the information that can broadcast for such business is as follows:

Flight AA 80 to Stockholm postpones till 6:10 in afternoon.

As former example, there is the text of underscore can be used as to apply mechanically message in terminal broadcasting with generate repeatedly, and sends with the text that italics row's information can be used as implantation.Note, only can be arranged to the only demonstration Flight Information relevant in his remote station for one, also can comprise selectively not and a general information that specific course line is relevant with this course line with the user in a course line.In this example, the time (6:10) is to implant text rather than one to apply mechanically message.Those skilled in the art are very clear, be one by some speech or the specific collection of constantly forming regulation apply mechanically message or rely on that many other schemes for replacement all are available in the selection of implanting text.

When the such big airport of one of bad weather invasion and attack such as the O ' Hare of Chicago, having a hundreds of flight will be affected.Therefore, this complete information table may contain that hundreds of is capable to be similar to top illustrative information.These information may per hour will be upgraded several times.Therefore, this method of applying mechanically text does not reduce required broadcast bandwidth, thereby wishes have a kind of channelizing method to provide some correlations to reduce the required bandwidth of broadcast message on some subchannels.

Filter broadcast information may also be desirable, because a user may only be concerned about limited subclass in the available broadcast message.For example, a user can be with the flight number of being paid close attention to, and for example AA 80, the input remote equipment.So if the information of relevant this particular flight of paying close attention to, the user just can obtain alarm (for example audio sound).On the channel of speech amplifier ground, can use some change sign or time stamps, in order to avoid when receiving same information afterwards, retransmit alarm.

More than by more detailed explanation to typical quotation and sport score information service, illustrated according to the present invention and can what use is made of channelizing technology send various forms of information expeditiously, used the very nervous broadcast resource related with radio communications system to reduce.These technology can be promoted as follows.

According to the present invention, in a travelling carriage, show, storage or layout and broadcast message that needs are handled can be combined into the set that some are made up of information word, will be called " incidence set (associations) " here.Information word can be that significantly (for example, a bit flag or bit section) also can be (for example, the ordering) that implies.Generate at least two incidence sets for a given information service with layered mode, this is based at least one unit of recognizing in an incidence set and compares with at least one unit in another incidence set and have different bandwidth demands.The unit that the bandwidth consumption of first incidence set in this incidence set is bigger and in this incidence set, set up a relation between another unit that needs less bandwidth to transmit.Second incidence set also comprises a plurality of units, and one of them is the part of first environment significantly or impliedly, has therefore set up a link between them.

This imagination is illustrated in Fig. 8.Wherein, each incidence set is represented with a rectangle.The circle that each information word is used in the incidence set rectangle is represented.Represent an implicit information word with the circle that bracket has been drawn together.Horizontal line is represented a relation that is used for making the efficient information rate channelizing that needs transmission, and vertical line or the vertical line of cardinal principle are illustrated in the link between the interior unit of different incidence sets.In fact those skilled in the art are appreciated that a relation between each information word in an incidence set, but some correlation can be used for providing a kind of mapping in a remote terminal, and other correlation is not.The combination of the link between the relation between some units in an incidence set and some units in different incidence sets provides a kind of optimized mechanism of bandwidth usage that makes.In general, the first number in the incidence set number is related with each is arbitrarily for any information specific business, will be determined in the frequency that travelling carriage need upgrade by type and these information words of information word.

In order to make this abstract concept more clear, consider the example of previously described quotation embodiment, describe with the incidence set of the popularization shown in Fig. 9 (a)-9 (c) and the structure of unit now.Wherein, first incidence set is the paper title incidence set.Information word in this incidence set comprises the information word that those more often do not send, for example complete paper title, the title of the securities market related with security.In addition, the mark title is the part of this incidence set because desirable be a kind of relation of between mark title and paper title, setting up, this relation can be used for optimizing the bandwidth usage of quotation business.

Second incidence set is the opening price incidence set.The opening price incidence set comprises opening price information word, label information unit significantly and anyly can for example notify user's dividend lastest imformation when a kind of specific security pay at maturity dividend than slightly frequent other information words of some transmissions of the unit in first incidence set.In this example, the order of the information of transmission, for example the order of label information unit forms an implicit information word (as by shown in the bracket), is called sequence number, and unit is relevant with label information.

The 3rd incidence set is the ups and downs incidence sets.Here, sequence number is obviously to send, be provided at second with the interior unit of the 3rd incidence set between link.For each security also sends the ups and downs value.Two relations that utilization is set up in first and second incidence sets, be paper title-mark and mark-sequence number, by these yuan of link between incidence set, travelling carriage just can read the ups and downs channel, and according to the order demonstration of an information appearance corresponding complete paper title related with each value, and system only need send a sequence number and a ups and downs value.

Show two alternative two examples in addition at Fig. 9 (b) and 9 (c).In Fig. 9 (b), sequence number second incidence set be obviously send and be implicit the transmission in the 3rd incidence set.In Fig. 9 (c), ack number also can be the implicit unit of of the second and the 3rd incidence set.

Other modification will be tangible.For example, be linked to an incidence set though these examples that Fig. 9 (a)-9 (c) illustrates guarantee each incidence set by the direction of each layering, each incidence set also can respectively be linked to one or more other incidence sets by each direction.In addition, in incidence set, can provide the correlation of any number, to reduce the amount of information that in having the environment of less circulation timei, sends.Incidence set can send in the different time, for example between trade date or after the day of trade, also can send simultaneously.If send simultaneously, can be asynchronous transmission, promptly use different circulation timei and/or content refresh rate.Be appreciated that phrase " circulation timei " refers in particular to the time quantum between the kindred circumstances that repeats an information specific unit, for example at the time quantum of broadcasting on the ups and downs channel between the ups and downs information word related with ERICY.Phrase " refresh rate " refers to upgrade time quantum between the value related with each situation of an information specific unit by business operation side, for example the ups and downs value of the ERICY stock that professional operation side's renewal is once broadcasted on the ups and downs channel how long.The circulation timei of given subchannel or incidence set can be different with refresh rate, and circulation timei also can be different with refresh rate between different subchannels and incidence set.For example, some value if refresh time greater than circulation timei, just can be replayed.In this case, can to indicate the information of current broadcast be new or replay with a change sign.By adopting channelizing technology of the present invention, can reduce the bandwidth requirement of channel minimum in this hierarchy or reduce the repetition period of circulating.

Except the high efficiency broadcast resource that utilizes, channelizing and coding techniques that the present invention proposes also have another important benefit, and specifically application program has the ability of the information content of knowing that it receives on each broadcast channel or subchannel.With for example directly the business of the text message that on beep-pager, shows of broadcasting compare, here channelizing of Ti Chuing and coding techniques provide tangible or implicit for being with or without the knowledge that receives this information for receiving equipment.For example, consider a kind of broadcast information services of broadcasting in the lower mode of bandwidth efficiency, the message that broadcasting word for word shows, ERICSSON 53 3/8+1/2 on paging equipment.Because this message shows that word for word beep-pager needn't know that it has received this information, therefore also just can not operate this information easily or distinguish whether any information specific receives.

On the contrary, channelizing and coding techniques that the present invention proposes have been set up some structures and relation between information word, except the bandwidth efficiency height, can also be used to having received and which is for example because the information that do not receive of channel error for which information word remote equipment provides about.In addition, remote equipment knows that more conveniently the ability of the content of the information that is received makes it be easier to tissue, demonstration and management data, and owing to allow new information word to add, thereby improved back compatible.

Speech amplifier field information business provides another example, shows opposite with the free-format text to make remote terminal know the benefit of content with channelizing form broadcast message.Be difficult on screen, all illustrate the information of all flights that enter to search the information related, if any a driver in the automobile that To Airport advances with his flight.

Though not concrete here the discussion, those skilled in the art be appreciated that network operator and system's operation can wish to formulate the monitoring access such as here illustrate those the technology and the process of broadcast information services.In the common unsettled U.S. Patent application No._ " access control of broadcasting service " (" Broadcast Service Access Control ") that proposes with same date of the application, some special technologies have been disclosed at Alex K.Raith, these broadcasting service access control technology can combine for referencial use the quoting of row here that this application disclosed with the channelizing and the coding techniques that disclose here.

Though the present invention is illustrated in conjunction with the quotation business, the personnel that are familiar with this technical field are appreciated that the present invention is equally applicable to other such systems to users broadcasting information.For example, be to be noted that (layering) channel of these links of explanation can send here on the channel of any kind.Therefore, any information word that sends on the channel of link in a kind of specific transactions can send on the point-to-point channel of a broadcasting, also can be when making telephone set by local measure (for example, infrared, cable, local radio communication) send into telephone set, be stored in this equipment.Therefore, ups and downs channel, sport score channel, air harbor status channel or the like can send rather than send on a broadcast channel as a point-to-point message.This channel link allows to utilize any channel and is independently sending any time any channel.In addition, this logic channel is connected to the mode change easily of existing channel architecture, to adapt to different systems.The person skilled in the art can design the many modification and the combination of these technology of lecturing above by spirit of the present invention, and these all should belong to the row of the given scope of patent protection of the present invention of following claims.
