Description

Be used for and the method, mobile radio station and the base station that are surrounded by the message transmission of pass
The present invention relates to base station and the radio interface between the mobile radio station and the method, mobile radio station and the base station that are surrounded by the message transmission of pass through the TDMA mobile communication system, especially is what the GPRS-packet data services of crash time information was used in the GSM mobile radio telephone network.
Radio communications system is used to transmit data by electromagnetic wave through the radio station of emission and a radio interface between the radio station of reception, and wherein radio station generally is not actionless.An example about mobile communication system is a known GSM-mobile radio telephone (global system for mobile communications), wherein provides the channel that is formed by a narrow-band and time slot to be used for the transmission user signal respectively.Because the subscriber signal in a channel in time with frequency on other subscriber signal be what to separate, so the radio station that receives can detect these subscriber signal data.By the formation of time slot, finish time-division multiplex-user and separate, and therefore finish TDMA (time division multiple access) mobile communication system.
The radio station of the network side of mobile radio telephone is a base station, and it is through a radio interface and mobile station communicate.Transmission from the mobile radio station to the base station is called up direction, and the transmission from the base station to the mobile radio station is called down direction.Channel forms by at least one time slot shape of each time-division multiplex-frame.At this moment a plurality of time slots-frame forms a grand frame.In addition carrier frequency and perhaps frequency jump series describe the feature of channel.
In order between two communication terminals, to transmit data, can employ and connect the scheme that relevant scheme is connected with logic-based, during the whole transfer of data with the situation that connects relevant transfer of data under, must the configures physical resource between two communication terminals.
In configures physical resource that needn't be lasting when transfer of data is carried out in the logic connection.An example to a kind of like this transfer of data is the bag transfer of data.Between the total data transmission period, exist the logic between two communication terminals to connect here.Yet physical resource, only just configuration during the transmission time of original packet.This method builds on the following basis: promptly data may occur between its long interruption and form transmission with short packages.Between the rest periods between the packet, physical resource can connect domination for other logic.With regard to logic connects, saved physical resource.
From the known package transmission method of German patent DE 44 02 903 A1 is to be in particular the communication system that has limited physical resource to use.It is for transmitting non-critical temporal information exploitation, and wherein especially be little important the time of delay of the message transmission of up direction.By the suitable allocation in the resource of the radiotechnics of down direction, can react to the crash time information that network side arrives in base station in mobile communication system.This is impossible for up direction, because the network side that is distributed in of radio resource carries out, the understanding that crash time information is existed disperses to exist at mobile radio station.Send in an access channel by passive mobile radio station being used to set up the request that radio technical resources that logic connects distributes, this access channel is distributed to mobile radio stations all in radio plot for this purpose.
Task of the present invention provide a kind of adapt to better that the crash time is used, with the information transferring method and the device that are surrounded by the pass.This task solves by method with claim 1 or 10 features and the mobile radio station with claim 17 feature and by the base station with claim 18 feature, and useful development of the present invention should be quoted dependent claims.
The present invention relates to base station and radio interface between the mobile radio station and the transmission method that is surrounded by the crash time-critical message of pass by relevant TDMA mobile communication system.During logic connects to the request of up direction radio technical resources, by having mobile radio station to the business record of crash time information,, on prior precise time point, in the channel of unique part of distributing to this business record, send at up direction by base station assigns.The base station receives this request, assesses it, and carries out the distribution that radio resource changes in order at up direction useful signal to be transferred to above-mentioned mobile radio station immediately.
Therefore for the signaling of up direction resource-query, mobile radio station is no longer relevant with the channel allocation that relates to the base station.Mobile radio station itself can determine the time point of resource-query.Resource up to radiotechnics is used for being reduced in the time of delay of the crash time of up direction information.
Development in a time slot the 1st radio blocks synchronous transmission useful according to the present invention given radio interface, so preset time is put the 1st radio blocks and arrived the base station in time slot, and in same time slot, have at least and separate appreciable one the 2nd radio blocks with the 1st radio blocks and have request and transmit.Therefore these requests can add additionally that the 1st radio blocks transmits together, and the radio technical resources that not has other is pind down.Especially in the time slot that has the access wireless electricity piece that shortens, stay the space that is used for the 2nd radio blocks.
Divide acquisition by the corresponding segment of time slot and transmit the more possibility of big data quantity.Thereby utilized radio technical resources better.Therefore time slot is not only distributed to mobile radio station but also can be utilized by a plurality of mobile radio station independently of one another.The radio blocks in time slot that guarantees synchronously by transmitting terminal can not arrive simultaneously, is to assess dividually therefore.
The radio blocks that transmits in a time slot after further shortening can have identical length,-therefore create the special time slot of the radio blocks of a plurality of shortenings ,-or represent dissimilar radio blocks-therefore can utilize the existing structure of time slot of mobile communication system better.Under the situation of identical radio blocks length, introduce a number of standardized block length, these block lengths are to fill up time slot like this, produce the little transit time of not utilizing as far as possible so that produce, and fill up a time slot with two, three or more radio blocks as required.At this moment it is sharp beginning to arrange the some time of advent of the 1st radio blocks to have according to time slot.More made full use of the duration of a time slot thus.Therefore the time bias value that has determined, also can accept, and extra computing cost is unnecessary the preact time.
According to another useful development of the present invention, send the request that has access wireless electricity piece.Access block only is used for the adjustment of preact time usually, and is sent at regular intervals by mobile radio station.The information warp is deposited in this access wireless electricity piece the request of the resource of the radiotechnics of up direction according to the present invention, and need not be the more expenses of signalling expense.
If select this request, be favourable when being used for access wireless electricity piece then in that the time slot of more number more (for example more than the time slot of GPPS) now is provided.Therefore can alleviate the burden of other signalling possibility, and further shorten delay till distributing radio technical resources at up direction.
According to the 3rd other development of the present invention, be not to offer in the time slot used of bag transfer of data to send request yet.Exist and the other repeatedly parallel bag transfer of data of transport-type (parallel with voice transfer at GSM) in mobile-communication system, therefore, the possibility of signalling additionally is used for up direction transmission faster except the channel of bag transmission.
In having the ability to form simultaneously the mobile radio station of multi-slot more, can on one or more channels, send request selectively.Therefore mobile radio station carries out ruling to the signalling channel of selecting.The resource of thereupon selectively one or more channels being distributed simultaneously radiotechnics.Therefore the mobile radio station ability that restricts a plurality of time slots only relates to the transmission of subsidiary signalling message or also only relates to the transmission of crash time information.It relates to the reception of down direction in addition.
Through the base station of TDMA-communication system and the radio interface between the mobile radio station, be step below during logic is connected, having arranged with another solution route of method that is surrounded by the pass about the crash time transmission of Information.Between mobile radio station and base station, fix on up mobile radio station in the radio blocks of message transmission approximately and allow to send request the radio technical resources of up direction.Mobile radio station sends such request, and wherein this request package contains the indication of pass up direction mobile radio station in the resource of that time point requirement radiotechnics.The base station receives this request, it is made assessment and immediately the radio technical resources of up direction is changed distribute to this mobile radio station.
Therefore reduce the delay that distributes and cut down extra informationization.Mobile radio station itself can influence the data transmission rate of up direction.
Useful characteristic according to this solution, mobile radio station has distributed certain radio blocks series (for example every one, two in each channel ...) be used in the long duration, mobile radio station signals to the base station in block of information, distribute to which does not need them in the original radio blocks of base station.This class signalling guarantees that mobile radio station has the resource of the radiotechnics of enough up directions.If do not need radio technical resources, then they can fully be utilized after open other connection.
According to expansion of the present invention, the distribution of radio resource is relevant with the business record of distributing to mobile radio station.The mobile radio station that only has certain business record of relevant crash time information just allows to send a request or only considers its request.Therefore stoped this signalling approach be used for a plurality of mobile radio stations with and fast resource request blocked the application of crash time.
The mobile radio station of predetermined number of only permitting having the business record of relevant crash time information is in the channel with suitable manner.This number may be complementary by approach to signalling.
If for business record is given mobile radio station priority allocation extraly, then have only the mobile radio station of certain priority to allow repetitive requests in certain period.Therefore preferential to these requests with special crash time application.
Above-mentioned other embodiment of the present invention also can make up, so that improve the distribution at the radio technical resources of up direction.

Figure 10 illustrates the block diagram of a mobile radio station, and
Figure 11 illustrates the block diagram at a stylobate station.
Time-division multiplex-mobile radio system of Fig. 1 for example is a GSM-mobile radio telephone network GSM, and it comprises a base station system BSS with a base station controller BSC and a base station BS at least.In the radio operating radius of above-mentioned base station BS, there are some mobile radio station MS.Base station system BSS produces the connection to the miscellaneous equipment of GSM-mobile radio telephone network GSM.In base station controller BSC, replenish a control appliance SE who is used for mobile radio station MS radio resource allocated.And this control appliance SE also can realize in the other equipment of mobile radio system.
These miscellaneous equipments for example are mobile switching centre MSC and the unit that is used to realize IWF IWF.The acting in conjunction of mobile switching centre MSC and IWF IWF produces the packet switch platform that is also referred to as GSN (GPRS Support Node).The packet switch platform is connected to the mobile switching centre MSC that is used for the language transmission, and it can be used as special unit realization in addition.
GSM-mobile radio telephone network GSM can be connected with other communication network.For example another communication terminal KEQ be can be connected with the GSM-mobile network through a fixed network or itself be exactly the parts of this GSM-mobile radio telephone network GSM.
GSM-mobile radio telephone network GSM and known voice transfer are applied to wrap transfer of data concurrently.So be used to realize that the equipment of IWF IWF can make GSM mobile radio telephone GSM and data transmission network set up coupling also therefore in other communication terminal foundation coupling.
Radio interface between mobile radio station MS and base station be characterized as a frequency band and at least one time slot ts.According to Fig. 2 for example 8 time slot ts (ts0 is to ts7) be combined into a frame R.Frame period property ground repeats, the time slot of Chong Fuing wherein, and for example time slot ts=ts4 belongs to a channel.This time slot ts is used to wrap transfer of data as channel GPRS-K below according to GPRS (general packet radio business).A plurality of time-division multiplexes-frame R can be combined into a grand frame.
If a mobile radio station MS should utilize this business, then it is used short access block realization arbitrary access and changes to the control channel of giving according to the GSM-term.Confirm and arrange succession, for example relevant logic connects the temporary transient identification code (TLLI) of (stand-by state).If, then carry out the calling (page) of desired mobile station MS and carry out above-mentioned arbitrary access in order to be transformed into stand-by state at network side about other communication terminal KEG of packet data services should communicate by letter with mobile radio station MS.
In order to send the bag data at up direction, mobile radio station sends access block at the control channel again, then a short identifier, and GPRS-channel GPRS-K and by access block preact time announcement mobile radio station MS decision, that in GPRS-channel GPRS-K, use.Mobile radio station MS is in wait state subsequently.Be separated by 1 to 2 second in order to upgrade the access block ac1 that the preact time sends other in wait state.If mobile radio station MS will transmit data at up direction subsequently, then resend access block (example the 2nd radio blocks fb2 or followingly be used for the access block that time bias is used) as will be described later, this access block is made full use of by the control appliance SE of base station RS.The resource of distributing corresponding radiotechnics according to the possibility approach immediately.
Fig. 3 is illustrated in the type of GSM mobile radio telephone network some radio blocks commonly used.Wherein each time slot only transmits radio blocks, for example a ts4 forever.A radio blocks is introduced and termination these 3 starting of oscillation and the left alone without help assemblies that shake and be used for other that are used for equalizer by each 3.In time slot ts4 8,25 guard time keep need not, and at different time-gap ts4, unadjusted transmission time difference possible between the radio blocks of ts5 produces compensation.
The radio blocks fbn of a standard comprises 2, and (58 useful informations, 26 training sequence is in central authorities are embedded into this useful information.
In addition, be called the 1st radio blocks fb1 of access wireless electricity piece ac1 below being illustrated in, it has 8 beginning, and comprises training sequence and 36 useful informations of 41.At this moment the guard time that is used for access block ac1 extends to 68.25 altogether.Wherein 60 offer at least one the 2nd radio blocks fb2 domination, as following to point out, shorten access block ac1, because it offers following occasion promptly at the GSM mobile radio telephone network:, thereby still should realize those occasions of reliable reception at inaccurate transmitting time point although at the signal transmission time of the unknown.
This external Fig. 3 enumerates three schemes with demonstrating and is used to set up the 2nd radio blocks fb2, and these the 2nd radio blocks fill up time slot ts4.Arrive at by 2 time point t1 and t2 at the radio blocks ac1 of receiver place and fb2 and to indicate, this two time point is determining preact adjusting synchronously by the mobile radio station MS that sends after the time.Radio blocks ac1, fb2 does not overlap.
Fig. 3 the 2nd radio blocks fb2 a) comprises training sequence and each 2 data block of 17 of 26 standard.According to Fig. 3 b) before 34 bit data block, carried out 26 training sequence.Therebetween at Fig. 4 c) therefore training sequence expands to 41 and following and having only 19 data block.Therefore the 2nd radio blocks fb2 respectively have only 60 long.Yet other radio block length also is possible.For example the 2nd radio blocks fb2 can be again by one or more introducings or termination.Expansion or shortening guard time also are possible when time slot finishes.
The 2nd radio blocks fb2 can include effective information and signalling information in data block, for example comprises to be used for the request req1 that the up direction radio technical resources distributes.
Fig. 4 illustrates an access wireless electricity piece ac1, to the request req1 of up direction radio technical resources and the information MS-ID1 that is used to discern mobile radio station MS embed in its data division, this access wireless electricity piece ac1 sends according to regular time intervals (240ms or 480ms), so that upgrade the preact time.The base station BS assessment request req1 that receives also distributes radio technical resources.
Fig. 5 illustrates the standard radio piece of up direction, wherein mobile radio station MS is used for also comprising information NBI (next piece indicating device) the information MS-ID1 of its identification except comprising, and this information points out which piece in the follow-up piece of up direction (for example the 1st, the 2nd or the 3rd) is necessary.The signalling that information NBI also can be used for relevant " which piece of piece in the original fixed allocation of up direction is not moved the station utilization ".Therefore these pieces can be used for connecting.If having the connection of crash time signal proposes again to radio technical resources demand more, the then piece that utilizes all to distribute again.
Utilize the standard radio piece of the down direction of Fig. 6, so that an identifier USF (up direction status indication) is distributed to the mobile radio station MS that represents with identifying information MS-IDI for the piece that utilizes up direction for this reason.Therefore base station BS is distributed in the radio technical resources of up direction.In the control unit SE of Fig. 1, distribution is entered a judgement.
Fig. 7 is illustrated in the frame structure of the radio interface in the up direction, and it has two frame R of demonstration, and this two frame comprises 8 time slots of time slot ts0 to ts7.Time slot ts1 and ts4 are exactly the channel GPRS-K that distributes to packet data services GPRS.Another time slot ts0 is exactly a more GSM channel of standard, and it also is for the signalling purpose, for example as access channel RACH.
The mobile radio station MS that has crash time information, (this crash time information should be transmitted through packet data services GPRS) at this moment can send request req1 and also be distributed in upstream or downstream direction resource where necessary in two channel GPRS-K in two channel GPRS-K.Mobile radio station MS also can send the rge1 that asks to the up direction radio technical resources in access channel RACH in addition, and this access channel RACH is general not for packet data services GPRS reservation.
By above-mentioned measure or the combination to them, the application of crash time also can be supported in packet data services GPRS.
Fig. 8 simplifies the flow chart that the crash time message transmission is shown.
In the 1st step (1), mobile radio station MS requires an interior piece of bag data channel QPRS-K of up direction (UL).
In the 2nd step (2), therefore base station BS also assigns piece B6 at up direction at down direction (DL) GPRS-K DL (its radio technical resources perhaps is to prepare for other mobile radio station MS) in piece B4 for sending USF at the desired mobile radio station MS of step (1).
In the 3rd step (3), mobile radio station sends crash time information and points out that by NBI mobile radio station needs another piece simultaneously at up direction.
In the 4th step (4), distribute the next piece of tight dust at up direction.
Mobile radio station MS also can require all other piece in this way, in the mode of the analog value of mobile radio station by NBI to its indication.NBI has stored piece B4, B5, B6.If be subjected to data transmission rate constraint (half transfer rate) only to need per two (every one), then this equally also can control by said mechanism.
Fig. 9 illustrates the radio interface that is used for the TDMA/CDMA transmission, a frame of one of them broad band channel, and for example 5MHz comprises 16 time slot ts0 to ts15.Part 1 for TDD-pattern (time-division multiplex) time slot is used for up direction, and part 2 is used for down direction.The 1st time slot ts0 that relies on the up direction utilization points out that a plurality of channels are differentiable by independent extended code C1 to C8 in time slot ts0 with demonstrating.
Part extended code C1 stores to the access channel RACH that C6 can be mobile radio station, and other extended code C7, C8 is used for the useful data transmission in useful data channel TCH.And in access channel RACH, carry out the differentiation of mobile radio station MS.Extended code C3 distributes to all mobile radio station MS to C6, and remaining extended code C1, C2 distributes to independent mobile radio station MS A to L.At this moment the channel that forms by extended code and time slot is divided in time again, can send the request that radio technical resources is distributed so go up nonoverlapping radio blocks a plurality of mobile radio stations in a time slot by the short time, and can not bump against.
Can realize being distributed by the definite part of mobile radio station to a channel according to business record, this channel is used for the fast access of up direction radio technical resources.For at mobile radio station and base station MS, this business record of the business that should transmit between the BS can rely on the maximum access delay that allows, data volume, data transmission rate, the priority of mobile radio station MS or compress quality of service (QOS quality of service) jointly and determine.When business record prepares fast to provide the crash time mobile radio station MS to be carried out preferential processing during information according to the up direction transfer resource.
Such business for example is:
-have a speech business that is interrupted between delay, lower data transfer rate and the voice messaging of minimum permission,
-have the delay of less permission, a video traffic of the high data transmission rate (to 2 megabit per seconds) that between minimum value and maximum, fluctuates,
-have small amount of data but relevant remote measurement-transmission with access delay (for example warning-message) of minimum permission with desirable application.
If all the other parameters of dedicated radio link (as for example transmitted power and preact time) then just can be indicated with the indivisible data of base station BS according to the present invention: the radio technical resources that presses for up direction although transmission is interrupted in fact still to keep storing.Can avoid by the parameter that upgrades, long training sequence or Mi Tabeien sequence must be arranged the radio blocks of the signalling that is used for the requirement access.Therefore radio blocks is extremely lacked and can be sent in a time slot with other radio blocks.
Therefore a channel is divided into a plurality of subelements, and these subelements are accurately distributed to each collision of a mobile radio station-get rid of subsequently-or distribute to a group mobile radio station MS I+J.Distribute to channel of mobile radio station MS or partial channel and do not mean that therein mobile radio station MS continues to send, and only represent that partial channel distributes to it in the situation that it can send specially.
The mobile radio station MS of Figure 10 comprises a control board T, a signalling treatment facility SP, control appliance ST1 and transmission/receiving equipment SE/EE.At the control board place, the user can import, in addition to the input of priority P1, import to desirable business record DP1 input and in order to send a packet or realize desirable startup and import for the voice of communication terminal KEG being connected through packet data services GPRS by packet data services GPRS.
Be connected in the signal handling equipment existence according to the crash time information that should launch through other of packet data services GPRS and form request existing voice to connect or have crash time information (transmitting time be not video traffic or other business) arbitrarily, and send through transmission/receiving equipment SE/EE by aforementioned signalling mode to the up direction radio technical resources.
In control appliance ST1, select time slot ts and according to the preact selection of time transmitting time point of prior decision.If signalling treatment facility SP receives the distribution at the radio technical resources of up direction that sends from base station BS, then it circularizes subsequently the control appliance ST1 to its control.
The base station BS of Figure 11 comprises a transmission/receiving equipment SE/EE, and this equipment amplifies received signal, and is converted to Base Band and demodulation.The signal transformation that receives in analog-to-digital converter is the symbol that has discrete stored digital, for example digitlization.In serving as the signal evaluation equipment SA of digital signal processor for example, also handle access block ac1, and the standard radio piece.
The useful information of radio blocks and signalling information input to miscellaneous equipment in addition, for example in base station BS or base station controller BSC.Assess in control appliance ST2 for having the radio blocks of asking req1, table 1 comprises according to its identification MS-ID1 to the priority P1 of MS-ID4 mobile radio station MS distribution to P4 and business record DP1, DP2.
The mobile radio station MS that priority P1 or P2 explanation distribute allows to send the 2nd radio blocks fb2 as request req1.And the other mobile radio station does not allow to do like this.Priority P1 is the difference of P2: at priority P1, mobile radio station allows to repeat immediately the emission of the 2nd radio blocks fb2.Mobile radio station MS with priority P2 must wait for certain time interval.Therefore prevented that the 2nd radio blocks of different mobile radio station MS from over and over again cancelling each other mutually.
According to priority P1 and business record DP1, base station BS identifies the information of mobile radio station MS transmission crash time and Priority Service in the request req1 to the up direction radio resource.By mobile radio station MS to the desirable time point of radio technical resources, in control appliance, considered information NBI.
