Technical field
Present invention relates in general to wireless communication system, especially, relate to the distribution of wireless communication system user time slot.
Background technology
General packet radio service (GPRS) standard provides a compatibility standard for cellular mobile telecommunication system.When the GPRS standard guarantees that the travelling carriage (MS) operated is in operating in according to the system of this standard manufacture in gprs system, can obtain communication service.For guaranteeing compatibility, this standard code radio system parameters and call handling process, comprise that by MS and the base station of serving this MS be to set up the control messages of calling out and exchanging between the element of the infrastructure that comprises the base station, performed call treatment step.
In the GPRS communication system, frequency bandwidth is divided into 8 time slots (using and the identical frame structure of global system for mobile communications (GSM)), and it provides physical communication channels, and these 8 time slots are formed a frame.For making MS receive transfer of data, for example from the network of this MS of service and be PS (packet switching) voice or the user data of form with radio downlink control (RLC) data block typically, this network must at first distribute the downlink packet data channel of one or more time slots that comprise that given frequency bandwidth is interior for MS.This network is by packet downlink assignment commands notice MS institute distributed time slot then.
In case time slot is assigned with, MS then only monitors institute's distributed time slot for receiving data.These time slots keep distributing to this MS during Temporary Block Flow, perhaps remain to MS always and receive grouping time slot reconfigure command.Yet wherein one or more previous distributed time slot become when can be used for additional allocation to MS, and situation will occur.For example, Fig. 1 has described according to prior art exemplary time slot allocation in frequency bandwidth.At the first period t
1, corresponding to the transmission of the first down wireless link control data piece, each time slot among 8 time slot 100-107 of a frame is assigned to MS.In the GPRS communication system, voice, user data and control information by air interface with block movement.Each piece comprises 4 pulse durations, and it sends on a physical channel continuously.Just, each piece uses 4 time slots to transmit, and in each of 4 continuous frames, 4 time slots comprise identical time slot.As shown in Figure 1, MS is assigned with 6 in 8 time slots, and promptly MS has been assigned with time slot 100-103, and 105 and 107, be used for transmitting first all 4 frame to MS in first period, each MS utilizes the identical time slot that can be used for this MS.The MS that for example has been assigned with time slot 100 utilizes in frame 1,2,3 and 4 time slot in each to be used at transmission block 110, and the MS that has been assigned with time slot 107 utilizes in frame 1,2,3 and 4 time slot in each to be used for transmission block 117.Yet, be assigned with wherein two time slots, promptly time slot 104 and 106 MS utilized to be less than the available time slot (the time slot of Li Yonging by idle time slot do not indicated) of MS in four frames in first period.For example, assigned slot 104 and 106 MS may receive voice, rather than data, because the sporadic characteristic of voice, the time slot of use is less than four available time slot.
As a result, at the second period t
2In, corresponding to by each distributed time slot 100-103,105 and 107 second transmission, and the 3rd period t
3In, corresponding to by each distributed time slot 100-103,105 and 107 the 3rd transmission, two additional time slots (time slot 104 and 106) can be used for redistributing.For example, the MS of assigned slot 100 transmits second 120 in second period, transmits the 3rd 130 in the 3rd period.Simultaneously, time slot 104 and 106 is not used, therefore second and the period 3 in in four frames sending each, can be used for redistributing.Yet in order to redistribute time slot to MS and before reusing this time slot, network must at first transmit the grouping time slot and reconfigure message to MS, waits for the affirmation of MS to this message then.This signaling consume system resources and time, the result causes order not carried out by block-by-block, and the system resource free time, by in the second and the 3rd period among Fig. 1 shown in the idle time slot 104 and 106.
Therefore, need a kind of time slot method and device of dynamically distributing, it promotes to reuse time slot more quickly than what prior art allowed.

With reference now to Fig. 2-5,, a kind of method has been described, the MS allocation of downlink time slot that communication system 200 is dynamically served for this communication system by this method.Fig. 3 be carry out by the Access Network of Fig. 2 according to one embodiment of present invention, the logical flow chart 300 of allocation of downlink time slot method dynamically.Fig. 4 is a block diagram according to an embodiment of the invention, and the exemplary allocations of communication resources of downlink time slots in the given frequency bandwidth is described, Fig. 5 is a block diagram according to another embodiment of the invention, and the exemplary allocations of communication resources of downlink time slots in given frequency bandwidth is described.
For example, as shown in Figure 4, Access Network 220 can distribute time slot 401 to give MS 202 in down link 212.By another example shown in Figure 5, Access Network 220 can distribute time slot 501 to give MS 202 in down link 212.For principle of the present invention is described, and in no case limit the present invention, Figure 4 and 5 further described in the down link 212 in a plurality of time slots and with the distribution of other time slots of time slot 401 in same frequency bandwidth of distributing to MS 202, time slot 500 and the 502-507 among time slot among Fig. 4 400 and 402-407 and Fig. 5 just, distribute to other MS of Access Network 220 services, for example MS 208.That is to say that time slot 500 among the time slot 400 among Fig. 4 and each among the 402-407 and Fig. 5 and 502-507 distribute to other MS except MS 202.
Access Network 220 passes through the corresponding first down link RLC data block then at the first period t
1Transmit data to each MS that is assigned with time slot 400-407 (perhaps about the 500-507 among Fig. 5).For example, about Fig. 4, Access Network 220 by time slot 401 and frame 1,2,3 and 4 at period t
1Transmission block 411 to MS 202, and, Access Network 220 by time slot 403 and frame 1,2,3 and 4 at period t
1Transmission block 413 is to the MS that is assigned with time slot 403.Similarly, about Fig. 5, Access Network 220 by in time slot 501 and frame 1,2,3 and 4 each at period t
1Transmission block 511 to MS 202, and by in time slot 505 and frame 1,2,3 and 4 each at period t
1Transmission block 515 is to the MS that is assigned with time slot 505.Successively, the MS demodulation of each assigned slot is included in the data in the time slot of distributing to MS.As known in the art, typically, in the GPRS communication system, need four time slots to be used for transmitting the down link RLC data block.
In first period, Access Network 220 determines that further (310) distribute to second at least one time slot of other MS (for example the 2nd MS 208) except MS 202 and can be used for redistributing.For example, as shown in Figure 4, in first period, time slot 404 and time slot 406 (time slot 504 and time slot 506 among Fig. 5) all are not fully utilized, and that is to say, time slot 404 and 406 ( time slot 504 and 506 among Fig. 5) is idle in the part-time of first period, more particularly, in first period, time slot 404 and 504 is idle in frame 4, and time slot 406 and 506 is idle in frame 3 and 4.These idle display time slots 404 and 406 ( time slot 504 and 506 among Fig. 5) can be used for redistributing.For example, time slot 404 and 406 ( time slot 504 and 506 among Fig. 5) may just send the MS of voice to their correspondences, because the sporadic characteristic of voice communication is underused the time slot of distributing to corresponding MS in the first down link RLC data block period.
Can be used for redistributing in response to definite second at least one time slot, Access Network 220 distributes (312) this second at least one time slot to give MS 202.For example, as shown in Figure 4, Access Network 220 can distribute available time slot 404 to give MS 202.By another example, as shown in Figure 5, Access Network 220 can distribute available time slot 504 and 506 to give MS 202.In response to distributing this second at least one time slot to give MS 202, Access Network 220 is sent to the down link RLC data block of MS by the next one, just, and by at the corresponding second period t
2Be sent to MS 202 second (piece 521 among Fig. 4 among piece 421 and Fig. 5), and by before distributing to the time slot of MS, promptly the time slot 501 among the time slot among Fig. 4 401 and Fig. 5 is notified (314) MS institute distributed time slot.By this way, Access Network 220 can be by the time slot of next piece notice MS 202 dynamic assignment, and this next one piece is not considered to distribute and is transmitted and is transmitted by dedicated signaling or the Bearer Channel that has distributed further.Do not consider to distribute the next piece that is transmitted by utilizing, Access Network 220 can be notified MS up-to-date distributed time slot, and the overhead that does not need the particular message of prior art and do not need to consume.In addition, when before distributing to MS202 and being used to notify distributed time slot (401/501) when being Bearer Channel, then communication network 100 provides newly assigned time slot for the in-band signalling of MS.
Preferably, Access Network 220 notifies MS 202 distributed time slot by institute's distributed time slot in the header of next piece of identification.For example, Fig. 6 is the bit layout of exemplary downlink RLC data block 600 according to an embodiment of the invention.Down link RLC data block 600 comprises that expectation is used for the pay(useful) load 610 of MS and further comprises MAC layer header 602, and wherein MAC layer header 602 comprises effective loadtype data field 604, temporary flow identity symbol (TFI) data field 606 and last piece designator (FBI) data field 608.Access Network 220 by in the pay(useful) load type data field, comprise bit mode ' 11 ', be used for which MS to 600 expectations of MS indicator collet, for example MS 202, and it is that Access Network will transmit the data block of data to MS through time slot new except that distributed time slot.Further, because when the piece that comprises time slot allocation is last piece of down link TBF, dynamically distribute time slot may be worth not quite, Access Network 220 is instruct MS in the header of next piece further, just whether MS202 can ignore in the piece all information except that uplink state flags (USF), for example, because this is last piece of down link TBF, perhaps indicate this piece whether to comprise the identifier of assigned slot, this time slot should be used to monitor additional data by MS.For example, Fig. 7 is a form 700, has listed according to an embodiment of the inventionly may be assigned to FBI data field 608 and indicate the described various values that whether comprise the pointer of the time slot that points to dynamic assignment.With reference now to Fig. 6 and 7,, by in pay(useful) load type data field 604, be provided with bit mode ' 11 ', and in FBI data field 608 value of setting ' 0 ', Access Network 200 can notify MS 202 these MS can ignore the information of all except that USF in the piece.On the other hand, by in pay(useful) load type data field 604, be provided with bit mode ' 11 ' and in FBI data field 608 value of setting ' 1 ', Access Network 220 can notify MS 202 described and comprise point to distribute the pointer of time slot, just, specifically discern institute's distributed time slot, this time slot should be used to monitor additional data by MS.
Access Network 220 is discerned the time slot of distributing to MS by comprising the value relevant with time slot in the TFI data field 606 then.Fig. 8 is a form 800, lists various TFI data field 606 bit modes, and a time slot or a plurality of time slot relevant with each bit mode, and it is used in reference to the time slot according to the one or more dynamic assignment of the embodiment of the invention.Yet those of ordinary skill in the art recognizes that the various various combinations of bit mode can be used herein to the time slot of identification dynamic assignment, and the particular combinations of bit mode used herein can not have any restriction to the present invention.Shown in form 800, when dynamically distributing time slot for MS immediately after the time slot of Access Network 200 at the current MS of distributing to (current time slots (TS) adds 1, perhaps TS+1), 5 bits of Access Network 200 TFI data fields 606 are set to ' 00001 '.Under the situation of MS 202, its current assigned slot 401, bit mode ' 00001 ' will notify this MS time slot 402 in corresponding to the period of next piece, to be assigned to this MS.If Access Network be provided with bit mode ' 00111 ', this will notify MS: time slot 400, the time slot before the just adjacent current distributed time slot 401 has been distributed to this MS in the period corresponding to next piece.All bit modes as described herein, the bit mode that comprises the time slot of discerning dynamic assignment and relevant time slot, be stored at least one memory member 206 of MS 202 and in the memory of Access Network 220, for example at least one memory member 226 and 234 one or more in.
For example, with reference now to Fig. 4, Access Network 220 can distribute time slot 404 for MS 202 at the 3rd period t of second period and then
3Use.In this case and based on form 800, Access Network 220 will comprise bit mode ' 0001I ' in second 421 TFI data field 606, and second at the second period t
2In time slot 401 in be sent to MS 202.It is three time slots after the current distributed time slot that this bit mode notice MS 202 these MS have further been distributed time slot, this time slot, just next period (i.e. the 3rd period t
3) in 404, the three periods of time slot corresponding to the transmission of next piece 431.By another example, with reference now to Fig. 5, Access Network 220 distributes two time slots, promptly time slot 504 and 506 for MS 202 at the second period t and then
2The 3rd period t
3Use during this time.In this case and based on form 800, Access Network 220 will in second 521 TFI data field 606, comprise bit mode ' 11101 ', second at the time slot 501 and the second period t
2In be transferred into MS 202 once more.This bit mode notice MS 202 these MS have been assigned with two time slots again, i.e. time slot 504 and 506 is at next period corresponding to the transmission of next piece 531, i.e. the 3rd period t
3, wherein two time slots are respectively current distributed time slot 3 time slots and 5 time slots afterwards.
Refer again to Fig. 3, after the time slot of notice MS 202 dynamic assignment, Access Network 220 is in the 3rd period, distributes to first time slot of MS and additionally and dynamically distribute to after initial time slot allocation on second at least one time slot of MS to transmit (320) data to MS when initial.For example, about Fig. 4, Access Network 220 transfers data to MS 202 by time slot 401 and down link RLC data block 431 in the 3rd period, and further transfers data to MS 202 by time slot 404 and down link RLC data block 434.By another example, about Fig. 5, Access Network 220 transfers data to MS 202 by time slot 501 and down link RLC data block 531 in the 3rd period, and by time slot 504 and 506 and down link RLC data block 534 and 536 further transfer data to MS 202.In addition, in response to receiving second (for example piece 521 among the piece among Fig. 4 421 and Fig. 5), and header according to second, MS 202 determines that (316) distribute to the time slot of MS when initial, be outside 501 among time slot 401 among Fig. 4 or Fig. 5, MS has been dynamically allocated one or more time slots, and the time slot of identification (318) dynamic assignment, i.e. time slot 504 and 506 among time slot among Fig. 4 404 or Fig. 5.Then, MS 202 is at the 3rd period t
3In, monitor each time slot that distributes when (322) are initial, i.e. time slot 501 among time slot among Fig. 4 401 or Fig. 5, and the time slot of one or more dynamic assignment, i.e. time slot 504 and 506 among time slot among Fig. 4 404 or Fig. 5.MS 202 demodulation in the 3rd period (324) is included in the data in the time slot that is monitored, and logic flow 300 finishes (326) then.
By using the down link RLC data block that is sent to MS by first downlink time slots, notify MS the distribution of second downlink time slots, wherein the down link RLC data block is transmitted under regardless of the situation of distributing, the time slot of communication system 100 notice MS dynamic assignment, and do not need message specific in the prior art and consume excessive bandwidth.In addition, when first downlink time slots comprises the Bearer Channel of distributing to MS, this system will provide up-to-date distributed time slot for the in-band signalling of MS.
