Description

Headline hyperlink broadcast servie and system

Invention field

The present invention relates generally to information service is provided in wireless communication system, more specifically, relates to existing radio communication service and system broadcast information services is provided effectively.

Over nearest 15 years, commercial wireless communication obtains huge growth.Particularly, beep-pager and cell phone are given prominence to becomes equipment quite common in many urban facilities.These two kinds of communication equipments and back-up system thereof develop from different basic purposes, that is, that beep-pager is used for providing traditionally is unidirectional, finite information is to one or more end users, and cell phone is used for providing traditionally the bi-directional speech communication service.

Along with time and technological progress, the traditional functional differentiation boundary line between this Wireless Telecom Equipment of two types thickens.Beep-pager obtains some in the function that is provided by cell phone traditionally, and vice versa.For example, developed bidirection pager, it allows the pager carrier to send message to paging system, and these message can be forwarded to the opposing party then.Similarly, cell phone obtains to send and receive the ability of short (for example, about 160 alphanumeric notations) text message, and these message can detect on the cellular display.This evolution in the Wireless Telecom Equipment has caused the exploitation and the marketization of many new information services.

For example, paging system has been implemented provides broadcast information services (for example, stock quotes information service) to give a large amount of subscriber with beep-pager of being with display.These beep-pagers receive current price with a large amount of stocks or the associated information of other financial bond (such as option, futures or the like) and these bonds of demonstration periodically by air interface, like this, the user can follow the tracks of his or her marketable securities list situation.

The applicant expects that cellular user can be interested for similar information is provided in the Cellular Networks.Yet, cellular system, unlike paging system, be designed around following example traditionally: (1) distributes to limited bandwidth that the restriction of the frequency spectrum that honeycomb uses causes and (2) owing to most of limited bandwidth were preserved in point-to-point (for example the connection between cell phone and the system owing to be subjected to each supervising entity (for example FCC), the speech connection) consideration, have only quite little part to be preserved for broadcasting (that is, transmitting to the cellular point-to-multipoint of system, moving) from system.Particularly because this back characteristic, system designer is for the amount of information that sends on available broadcast channel and to repeat to send the consideration of frequency of this information very careful.Like this, provide broadcast information services to cellular radio Communication system can not be by broadcasting simply that all users want to show on their cell phone no matter assorted petty information the most flat-footed method and easily finish.

For example, consider a TDMA cellular radiotelephone system, wherein each radio frequency is divided into a series of time slots, and each time slot comprises the information burst from data source, for example, and the digital coding part of voice dialogues.By time-multiplexed those bursts relevant, can on each radio frequency, support more than one channel with different sources.Time slot is organized as tdma frame in succession, that have predetermined time duration.The number of the time slot of each tdma frame with share the different subscriber-related of radio-frequency channel simultaneously.If each time slot in the tdma frame is assigned to different users, then the duration of tdma frame is in the minimum time amount that is assigned between same user's the time slot in succession.

Be assigned to same user's time slot in succession, (they are not the time slot in succession on radio-frequency carrier usually) constitutes user's digital service channel (DTC).As mentioned above, this point-to-point typically resource, in fact, most of tdma systems are preserved most of available radio-frequency channels being used as DTC, thereby guarantee big volume of business.Yet as what be described in more detail below, digital control channel (DCCH) also is provided for Control on Communication signal and additional overhead information, comprising the mechanism that is used to be connected to wireless communication system and distributes DTC.

In the cellular system of other type, can find the resource allocation of similar type.For example, in code division multiple access (CDMA) system, channelizing is effective by using unique spreading code to come the spread spectrum data relevant with specific connection.This code (different with the time diffusion device with frequency or combine with frequency and time diffusion device) is equipped with to be used to extract the mechanism of the data that it wants to receiver, that is, by carrying out the composite signal that receives relevant with the code of the Traffic Channel of distributing to it.As tdma system, cdma system also is equipped with Broadcast Control Channel or other additional overhead signaling channel by to its known code of channel allocation.Yet as tdma system, cdma system is also wanted to keep compared with the broadcast message channel more resources (for example, code and power) to be used for Dedicated Traffic Channel.

Have some broadcast information services today, yet these existing business are the special business that not do not integrate with traditional cellular voice communication system, and they have and this integrated relevant very big shortcoming.For example, under the environment of Packet data service (such as the CDPD that in U.S.'s cellular frequency spectrum, adopts), a kind of like this business is arranged, it round efficient coding, reduce WEB (the Internet) the browser design of content.By using this business, the user will can read text in a small amount on quite little screen (for example, less than the text of 10 row), and the inquiry (being that tangible system inserts) that the text is in response to from the user presents.Every " page or leaf " that present on this screen may have the content that can further be selected.

For example, the stock quotes service page of demonstration can comprise the little form of Business Name.If the user selects specific company by keyboard, then send a request to a specific server in the network by the aerial CDPD of use is professional.Server sends new page to travelling carriage at information requested then.That this CDPD service class is similar to is traditional, based on wired Internet service, its difference is that the specific server that is connected to cdpd system uses special voice, gives the user so that more effectively present information in a small amount.Specific server can extract text message and remove the picture, colored or the like of high bandwidth from traditional WEB webpage.Then, text is sending to before the far-end unit, with on the bandwidth compared with the more effective mode of html language by reformatting and recompile (these html languages are to use with its original WEB form web page descriptor the time).

This microbrowser notion among CDPD, use, its original form developed so-called wireless application protocol (wap).Yet basic conception still is identical.It is that air interface (for example, GSM, IS-136, CDPD etc.) is irrelevant that WAP is designed to, and it provides improved flexibility and resource efficiency.

The another kind of technology of using in the current wireless system is to make up the dedicated system be used for information retrieval (for example, above-mentioned paging system).Different with cellular system, in paging system, basic (and the perhaps unique) business that is provided is the information broadcast business.All available information is broadcast to wireless device as the part of broadcasting service.The chance of the further information of request is not provided.

This a kind of paging system method in back needs very big RF bandwidth, because all information all must be broadcasted, or alternatively and more realistically, the amount of information that the user can insert must be limited.In the data volume that can offer subscriber (for example, send how many kinds of stock symbol/price) with the user for obtaining trading off and must make between the needed time of full detail collection (for example, how long user's stock symbol/price of receiving and cycling through predetermined number need spend) by service supplier.And all users obtain identical information, can not be specific user customized information.

Aforesaid CDPD/WAP method requirement user finishes the initial access to system, that is, and and the Internet inquiry.Be similar to traditional WEB usage, the user must store " bookmark " of interested " page or leaf ".The user typically initiates an access to specific business (for example entering into " bookmark ").The shortcoming of this method is that if there is specific incident to take place, then the user can not get information, unless its poll business (for example new business).

Traditional based on wired Internet WEB scheme in, the remedial measure of this problem is to introduce a kind of " advancing (push) " business, therein, network-based service is sent information to the user, it generally is updated when master data changes.Stock quotes, media event, sports tournament mark are for advancing professional typical application item.Little " banner heading " can be assigned to the PC screen, and it constantly upgrades with stock quotes.Yet, these based on wired propelling business in, the user must sign in to system, from professional server point, its using system resource.And because that these " propelling " business are based on is wired, they typically send all, relevant with represented topic, available/information of wanting at once, and this will need the very big bandwidth of wireless communications application.

Therefore, be desirable to provide technology and the system that broadcast information services can be provided in the restrictive condition of existing cellular broadcasting system.Particularly, wish broadcast information techniques and system that design is such so that they can adapt to the end user for quite a large amount of, may needs the demand of data updated quite continually, and make the use to rare broadcast channel resource minimize simultaneously.Such system should overcome the shortcoming of traditional paging system about bandwidth usage, does not also need the user to carry out specific system interrogation in the past in any information of reception simultaneously.

Brief summary of the invention

Exemplary embodiment of the present invention provides with effective and efficient manner uses broadcast resource to support the technology of broadcast information services by wireless communication system.The present invention is by short title or the proposition summary (for example news is provided with the hypertext form) of broadcasting only originally, thereby the capacity by the broadcast resource of broadcast information services consumption that makes minimizes.Hypertext can be a link (that is, the URL address) to the WEB network address, or just for the mark of the local identifier of cellular system, it is offering server for the location needed information of full text relevant with title with retrieval.

If the user selects this title, then in travelling carriage, produce request automatically, come all texts of requesting selected theme by using Packet data service for example or SMS business.Request to all the elements has comprised a destination-address, this server can send details according to this destination-address, and for example, this destination can be travelling carriage honeycomb identifier or another equipment, for example, the fax number in office electronic mail or hotel.Destination-address can be defined as untreated address area and add the identifier district, the type that latter's identification is relevant with this untreated address area, for example e-mail address, fax number, travelling carriage honeycomb identifier etc.

By originally a broadcast titles or theme are made a summary, only need in a small amount, cellular broadcasting bandwidth seldom, or ground of equal value, the time of the subclass of the specific details that acquisition may need is reduced so far, and making fully might be by using broadcast channel to send details in cellular radio Communication system.

According to exemplary embodiment of the present invention, do not need to send and obtain heading message by travelling carriage, only when asking details, the user just need insert.The present invention utilizes the combination of broadcast channel and point-to-point channel, so that effectively utilize frequency spectrum and provide wieldy and professional flexibly to the end user.

Particularly, exemplary embodiment of the present invention is described technology and the system that is used to provide broadcast information services, and this technology and system can reduce to use available quite rare broadcast resource in existing cellular radio Communication system.Therefore, these exemplary embodiments by at IS-136, particularly broadcast in the SMS channel (S-BCCH) available broadcast resource and describe.Describe below total relevant with the IS-136 system and particularly with some relevant details of broadcasting SMS channel, and omit other details, with the obstruction free description of this invention.Yet, interested reader can consult the U.S. Patent No. 5 that licenses to Raith etc., 603,081 and the U.S. Patent Application Serial Number NO.08/482 that submits to by Raith etc., 754, so that obtain relating generally to the system relevant respectively and particularly about the additional information of broadcasting SMS technology with IS-136.The above-mentioned United States Patent (USP) and the disclosure of U.S. Patent application directly are being hereby incorporated by reference.

Fig. 1 be presented at send on the carrier frequency, be built as the

time slot

1,2 that is included in succession ... in a series of

time slots

1,2 ..., N ... the general example of forward direction (or down link) DCCH.These DCCH time slots can be defined within the radio-frequency channel such as defined among the IS-136, and can be included in every n the time slot in a series of time slots in succession.Each DCCH time slot has one period duration, and it can be or not necessarily according to 6.67 milliseconds of the length of the DTC time slot of IS-136 standard.

As shown in Figure 1, the DCCH time slot can be organized as super frame (sf), and each superframe comprises a plurality of logic channels, is used to carry different types of information.One or more DCCH time slots can be assigned to each logic channel in the superframe.The exemplary downlink superframe in Figure of Fig. 1 comprises three logic channels: Broadcast Control Channel (BCCH) wherein comprises six time slots in succession that are used for overhead messages; Paging channel (PCH) wherein comprises a time slot that is used for beep-page message; And insert responder link (ARCH), wherein comprise a time slot that is used for channel allocation and other message.All the other time slots in the exemplary superframe of Fig. 1 can be dedicated to other logic channel, for example, and additional paging channel PCH or other channel.Because the number of travelling carriage is more much more than the number of time slot in the superframe usually, each paging time-slot is used for paging, and those share several travelling carriages of some unique feature (for example, the last figure of MIN).

Fig. 2 provides the block diagram comprising the exemplary cellular mobile radiotelephone system of exemplary base 110 and travelling carriage 120.The base station comprises control and processing unit 130, and the latter is connected to MSC 140, and MSC 140 is connected to the PSTN (not shown) again.Total aspect of such cellular radiotelephone system is known technically, for example consult and license to Wejke's etc., exercise question is the U.S. Patent No. 5 of " Neighbor-Assisted Handoff in a CellularCommunication System (the auxiliary handover in adjacent area in the cellular communication system) ", 175,867, with on October 27th, 1992 submitted to, exercise question is the U.S. Patent application No.07/967 of " Multi-mode Signal Processing (multi-mode signal processing) ", 027, these two patents are cited in this application, for your guidance.

A plurality of voice channels are handled by voice channel transceiver 150 in base station 110, and this transceiver 150 is by control and processing unit 130 controls.In addition, each base station comprises control channel transceiver 160, and it can handle more than one channel.Control channel transceiver 160 is by control and processing unit 130 controls.Control channel transceiver 160 is given the travelling carriage that is locked on this control channel at broadcast control information on the control channel of base station or sub-district.It will be appreciated that

transceiver

150 and 160 can be implemented as an individual equipment (for example, speech and control transceiver 170), is used with the DCCH and the DTC that share same radio frequency carrier frequency.

Travelling carriage 120 is received in the information of broadcasting on the control channel at its speech and control channel transceiver 170 places.Then, the control channel information that processing unit 175 is estimated to receive (feature of the candidate cell that locks onto comprising travelling carriage), and which sub-district definite travelling carriage should lock onto.Advantageously, the control channel information that receives does not singly comprise the absolute information of relevant its related sub-district, also comprise relative information about other sub-district adjacent with the related sub-district of control channel, as license to Raith etc., exercise question is the U.S. Patent No. 5 of " Method and Apparatusfor Communication Control in a Radiotelephone System (method and apparatus that is used for Control on Communication in the radio telephone system) ", 353, as described in 332, this patent is cited in this application, for your guidance.

Travelling carriage 120 comprises that also input unit 185 (such as keyboard) allows user and travelling carriage interaction.Display unit 190 (such as LCD (liquid crystal display) screen) provides image displaing information to the user.Travelling carriage also comprises memory 180.

In the exemplary embodiment of the applicant's invention, the transmission of broadcast message from the base station to the travelling carriage is built into a series of different types of logical frame.Fig. 3 shows the frame structure of forward direction (base station is to the travelling carriage) DCCH according to IS-136, and show two special frames (HF) in succession, each special frame preferably include separately main super frame (sf) and secondary superframe separately.Certainly, will recognize that special frame can comprise plural superframe.

Fig. 3 shows three superframes in succession, its each comprise a plurality of time slots, they are organized as logic channel F-BCCH, E-BCCH, S-BCCH and SPACH, are described in more detail below.Like this, only need point out that each superframe among the forward direction DCCH comprises the complete collection (that is, the collection of the 3rd a layer of message) of a F-BCCH information, use necessary that petty many time slot, and each superframe be from the F-BCCH time slot.Behind the F-BCCH time slot, remaining time slot comprises one or more time slots (or not having time slot) in each superframe, is used for E-BCCH, S-BCCH and SPACH logic channel.

With reference to Fig. 3 and more specifically with reference to Fig. 4, each superframe of down link (forward direction) DCCH preferably includes BCCH channel of broadcast control and short message service/paging/access channel.BCCH comprises fast B CCH (F-BCCH shown in Figure 3); The BCCH (E-BCCH) of expansion; With short message service BCCH (SBCCH), wherein some is used for carrying from the base station to the travelling carriage, general, relevant with system information usually.

The system information of F-BCCH logic channel delivery time strictness, such as the structure of DCCH, for connecting system is that important other parameter and E-BCCH change indicates that (it is at U.S. Patent application No.08/482, at length be described in 754, this patent application is to assign an application jointly, quote at this, for your guidance); As mentioned above, F-BCCH information complete collection is sent out in each superframe.The E-BCCH logic channel transmits compared with the more undemanding in time system information of the information that sends on FBCCH; A complete set of E-BCCH information (that is, the collection of the 3rd a layer of message) can comprise several superframes, and the starting point that does not need to aim at an EBCCH time slot of superframe.The SBCCH logic channel transmits short broadcast, such as stock information, advertisement and the interested out of Memory of various mobile subscriber.According to exemplary embodiment of the present invention, this logic channel can be used for supporting the two-layer information service that links mutually, and wherein title or summary are broadcasted continuously, and more detailed information can be broadcasted on request.

Exemplary title hyperlink business

According to the present invention, short textual description (for example, title, summary, theme etc.) can be sent out on the SBCCH or on its subchannel.Owing to recognize that the broadcast resource of existing cellular system is rare, the applicant predicts SBCCH (or in the system of other type its counterpart) can distribute its bandwidth between various broadcast information services (for example, stock quotation business, college sports information business etc.) possible case.Dissimilar business can be sent in a different manner effectively.For example, when the information relevant with specific business (for example comprises one group of renewable value, fail safe, sports tournament, weather, with the travelling etc.), then this information can and be encoded by channelizing, so that bandwidth usage optimization, as what submit to by the applicant on July 10th, 1998, exercise question is for as described in the U.S. Patent application No._____ of " Channelization and Encodingfor Text Information Services Transmitted viaRadiocommunication Systems (channelizing and the coding that are used for the text information services that sends by wireless communication system) ", the disclosure of this patent application is quoted at this, for your guidance.Yet some information of wanting not necessarily is suitable for technology described herein easily.For example, have the title and article that can just change fully and news, be not suitable for broadcasting by the channel of a series of classifications with very long detailed report every one hour.

The invention provides the technology that is used to solve such broadcast information services.At the beginning, a series of short messages of system broadcasts, they are received by remote equipment, and are used as selectable hyperlink.These hyperlink can be shown on remote equipment (for example mobile phone, wired PDA etc.).For example, consider a user who wants to catch up with the development of telecommunications world.This user can be provided by a kind of broadcast information services that provides about the data of various propositions, send following message (perhaps by using some coded system) comprising telecommunications and on the SBCCH subchannel, on the screen of user's mobile phone, be shown as follows after these message (or its part message):

ERICSSON BUYS MICROSOFT (link identifier), LUCENT STOCK PLUNGE (link identifier), AT﹠amp; T VENTURE (link identifier), IS-136 IN CANADA (link identifier) ...

(connotation of each English words in the top paragraph is: Ericsson buys Microsoft, and Lucent stock entangles firm, AT﹠amp; T takes a risk, at Canadian IS-136)

As what see above, the text message explanation that a part of the information of broadcasting on the S-BCCH subchannel relevant with this business is a summary, it is the context notification user of available, more detailed information (this information also is not broadcasted), the text message part of this summary can be shown, for you to choose.The information of the transmission of another part can be link identifier, and it can be effective WWW (World Wide Web) address (URL).Link identifier can or not necessarily be shown selective.Like this, alternatively, one group of message of demonstration can be read as:

LUCENTSTOCK PLUNGE AFTER PURCHASE OF MOTOROLAWIRELESSSYSTEM DIVISI0N ... or the like (that is: buying MotorolaAfter the wireless system portion, Bright NewsStock entangles firm ... or the like)

In a back example, link identifier does not have distinct demonstrating, but, use underscore to represent and link relevant information to the user.Like this, in this back example, two links are identified is used for a theme.Certainly, can use any designator of seeing, for example, highlight.Alternatively, the relation between the text of hyperlink and demonstration can be passed on by punctuate, and for example, the selection of any text between comma will cause single hyperlink to be activated.Among any embodiment in these exemplary embodiments, the selection that starts the display part of a hyperlink can be finished in any mode of wanting, and for example, places below any letter of a cursor in phrase, or the screen of use touch sensing, point to the link area of wanting.

Except the explanation and link identifier of summary, this system can broadcast the designator of the scale of the details relevant with each link identifier.This will allow user or travelling carriage to determine according to the scale of details and link relevant details and should how to be downloaded.For example, the details that scale is quite little can be used lower band width service, such as point-to-point SMS, and for link relevant bigger data block, can select data service in the mode of programming in advance by user or travelling carriage, for example, wherein the user can select in advance, feasible data file less than about 1kByte (kilobytes) is sent out by point-to-point SMS, and the data file that surpasses 1kByte should send to his her e-mail address, or is sent out by setting up the connection of circuit or grouped data in wireless communication system.Travelling carriage can be read automatically and link relevant scale designator by what the user selected, so that be identified for the down link transfer mode of the details that identified by hypertext link.Alternatively, the scale identifier can be shown as with short textual description:

ERICSSON?BUYS?MICROSOFT(22kB)，LUCENT?STOCK?PLUNGE(10kB)，AT&T?VENTURE(45kB)，IS-136?IN?CANADA(180kB)，...

(that is: Ericsson buys Microsoft (22kB), and Lucent stock entangles (10kB), AT﹠amp firm; T take a risk (45kB), at Canadian IS-136 (180kB) ...)

For example, when cursor is when being in the part of hyperlink of demonstration, the user can have the form of cursor and pushes options button and select one of hyperlink that shows by rolling, if or in remote equipment, use the touch sensing screen, as long as the hyperlink part of the message that shows by contact just can realize.Then, the user can be prompted to select the transfer address for details from the tabulation that comprises his her Email, fax number or the like, or imports an address.

And, can change with the output device relevant with the transmission form that links relevant detailed data with the down link transfer mode.For example, if user or mobile station in selecting SMS transfer mode then can transmit the information of the reinforcement group of first lower bandwidth.Alternatively, if select Email or facisimile transmission pattern, then can transmit the information of second higher sets of bandwidths.In this case, consider typical the Internet address, it can be that image/video strengthens.If the user selects the hyperlink relevant with such the Internet address, then image can be cancelled, and if select the SMS transmission then only send text, and if select higher bandwidth service (for example Email), then can transmit all image/videos.

Because title is by the broadcasting of system cycle ground, remote subscriber does not need connecting system (for example requested service channel) to read title.This is avoided utilizing uplink control channel or data packet channel capacity to be used for title and browses.And the user does not need to sign in to service server and obtains title, and this has been avoided the requirement to the wireless communication system resource.Different is, the user is activated for a group heading business by for example receiving one group of corresponding encryption key, and these encryption keys can be sent out by air interface, or are imported by means of keyboard by the user.Encryption key can for example, once be changed according to regularly in every month.Like this, service supplier (it is cellular operators not necessarily) can find out to have only the client of paying could insert specific broadcasting service.For the relevant further information that is used to control the example technique that is linked into such broadcast message, interested reader can consult submit on July 10th, 1998 by Alex K.Raith, exercise question is the U.S. Provisional Patent Application sequence number No._____ of " Broadcast Service Access Control (broadcasting service access control) ", the disclosure of this patent application is quoted at this, for your guidance.After being selected by the user of hyperlink, the transmission meeting of corresponding details is collected additional charge by service supplier, or a part that can be used as reservation title business is included by the gratis.

As described, exemplary embodiment of the present invention provides summary by (1) information provides details as broadcasting service and (2) in response to user's request, and has overcome the defective of known system.Set of titles that is used to broadcast or theme group can be organized as service groups, and these business can be preengage with the principle of " paying of wanting by you ".For example, a service supplier can be broadcasted a series of headline on a S-BCCH subchannel, and another service supplier is broadcasted the travel advisory title on second S-BCCH subchannel.Only Yu Yue business is made into for the mobile subscriber availablely, that is, the mobile subscriber can preengage a business and can read corresponding broadcast sub-channels, but not other business.

For title and particularly details are presented to the user, remote equipment can be installed to notebook computer or portable computer to the short haul connection device of this locality, for example, and infrared or local, low power wireless link.As mentioned above, the request for details can comprise destination-address.The type of destination-address can impliedly be stipulated and will be made the mechanism that is used for sending details by system.This mechanism as mentioned above, can be that the data (for example, CDPD in the gsm system or GPRS) of SMS message or circuit switching or grouping connect.

Alternatively, can ask a kind of specific mechanism significantly for the request of details by means of the transmission details.Certainly, the address that destination-address can be relevant with the remote equipment of request is identical or different.For example, the user may want that details are directed to the hotel as fax or be directed to its office electronic mail system as Email, rather than to his or her mobile phone, on this mobile phone, his or she rolled title and select to be used to receive the particular items of details.

The user can set remote equipment to wait for the specific indication set by the user (for example, specific key sequence) send for the request of details to system before.

Except with the man-machine interactively effect of broadcasting service, also automatic interaction can appear.For example, if stock quotes reaches certain level, the user can set the triggering for specific theme.When the condition that is triggered occurred, remote equipment can be set at predetermined place, transfer address request details automatically.When details are being can provide the time in travelling carriage or the equipment that accompanying, then the user is alerted.Another exemplary trigger is to occur specific word or specific word group in the title of broadcasting, for example, and ERICSSON (Ericsson).Remote equipment can be checked broadcast titles incessantly or routinely at interval, triggers so that determine whether to exist.When trigger event occurred, remote equipment can be reminded the user, allowed the user to determine whether should ask details thus, or when it is identified in short text summaries or the keyword in the title, can set the relevant details of request automatically for.

Except according to triggering automatically at the word of predesignating that in summary text explanation, sends on the broadcast channel or phrase the hyperlink, also can use classes trigger.Except text message, broadcast message can have link identifier, and the scale that has relevant details (classification district).This example format that is used for the transmission of broadcast titles hyperlink is displayed on Fig. 5.

For example, classification district numerical value 001 can be represented: following text message has been classified as news with relevant details, and classification district numerical value 002 can be represented: following text message relates to physical culture with relevant details.This district also can be used in automatic hyperlink activation, for example, for the predetermined relevant all titles of classification value, can ask details.

Except providing automatic hyperlink selects, can for example before the request that sends on the control channel for the details relevant, accumulate by remote equipment with various hyperlink for the request of additional information.Certainly, when hyperlink is selected, remote equipment also can send request (or by the user by manual type, or according to the triggering function of just aforesaid certain pre-programmed), yet, by obtaining several requests simultaneously, it might accumulate several themes before inserting carrying out single to system, so just and then minimizing obstruction and improve effective bandwidth usage.

Each broadcast titles and relevant link identifier thereof can have a plurality of detailed information files relevant with it.For example, the service broadcast relevant with newspaper links paper that can have various every days etc., and they all are can be available on specific network address.Under these circumstances, according to exemplary embodiment of the present invention, when this user wants a plurality of detailed information files from same source or position, might reduce the amount of information that in the request at it on the up link, sends it back by user of mobile station.This can be by providing local identifier rather than repeating complete chained address and finish, and their parts of can be used as request are sent out then.

For example, if provide local number 1-6 by the hyperlink of system broadcasts, and travelling carriage returns the request as it of the general hypertext link address that do not have local number, and then system can suppose that travelling carriage wants 6 all details pieces.Alternatively, if travelling carriage sends the general hypertext link that has

local number

1 and 2, then system will know which two detailed information files is that the user wants, and need not the repetition whole address relevant with network address or source.The decipher of local number can be by the cellular switch support, and can need the route that goes to the there.
