Detailed description of the invention
Fig. 1 has shown exemplary wireless communication network 10, and it is configured to provide according to reverse link rate control of the present invention.Network 10 provides in simplified form, so that discuss, but it should be appreciated by those skilled in the art that network 10 can comprise the entity that does not show, and shown entity can comprise additional complexity.In addition, should be appreciated that although in one or more exemplary embodiments, network 10 comprises the cdma2000 cordless communication network, the present invention is not limited to this, and network 10 can be based on other standard such as wideband CDMA.
Based on above-mentioned, network 10 is connected to one or more external networks 14 with communication mode with travelling carriage 12, for example internet or other public data network (PDN) and/or public telephone switching network (PSTN).In exemplary rough schematic view, network 10 comprises wireless access network (RAN) 16, and it is connected to one or more core net (CN) 18 with communication mode, and core net (CN) 18 provides again and the communicating by letter of external network 14.RAN 16 comprises one or more base station systems (BSS), and each base station system comprises base station controller (BSC) 30 and one or more related radio base stations (RBS) 32.Skilled person in the art will appreciate that other BSS configuration also is possible, for example the BSC logic can be entirely or is partly transferred to the RBS level, and the present invention has considered the variation that all are such.
In at least one embodiment, network 10 provides basic continuous rate controlled to one or more travelling carriages, and the one or more travelling carriages in those travelling carriages provide auxiliary discontinuous rate controlled as required.Here, " continuously " only means and generally repeats to send and do not have a rate controlled order of prolong interrupting.On the other hand, " discontinuous " means that the rate controlled command transfer can be " burst ", because they only mail to specific travelling carriage when needed, to replace or to revise basic rate and control.Therefore, the general rate controlled that the typical responsible basic rate control command of travelling carriage provides, rate controlled up to it need require to use the specific or group particular rate control of travelling carriage, in this case, these travelling carriages can be assigned to auxiliary rate control channel.
Remember this rate controlled, be appreciated that each RBS 32 can provide radio communication on one, two or more sectors: shown in RBS 32 each leisure be expressed as on three sectors of S1, S2 and S3 covering be provided.Should give term used herein " sector " wide implication, therefore it should be interpreted as the radio coverage area of expression definition.In exemplary definition, the zone of intersection of the given radio carrier (frequency) of given geographical coverage area is represented to have in the term sector.Therefore, shown RBS 32 can utilize two or more radio carriers that overlapping sector is provided.Under any circumstance, this type of details is unimportant to understanding the present invention.Yet related to the present invention is to it should be appreciated by those skilled in the art that method of rate control disclosed herein can be adjusted in the sector and between the sector as required.
Fig. 2 has shown that an exemplary base station is BSS, and it comprises BSC 30 and RBS 32, and they represent to help concisely with the functional unit of simplifying.Should be understood that BSC 30 generally is configured to support a plurality of RBS 32, and each RBS 32 can be configured to support a plurality of radio sector.
Under any circumstance, BSC 30 comprises control processing circuit 34, for example one or more signal processors, microcontroller etc., they are configured to provide call control logic, being used to set up, keep and remove the logic relevant with voice that stop therefrom starting on each travelling carriage 12 that obtains RBS 32 supports and/or data call is connected, and comprise the interface circuit that is used for being connected to RBS 32 with communication mode, for example be used for back transfer interface (backhaul interface) circuit of E1/T1 circuit, microwave etc.Interface circuit 36 can comprise other possible different interface, be used for communicating by letter with CN 18, for example communicate by letter with the mobile switching centre (not shown), in addition, BSC 30 can be included in Packet Control Function (PCF) that radio packet (RP) interface is provided between the packet side of CN 18 and the RAN 16 or similar entity, or relevant with it.
RBS 32 comprises forward/reverse link control and signal processing circuit, and they are referred to as treatment circuit 40 in this article.RBS 32 also comprises transceiver resources 42 and relevant reception/transmitting antenna unit 44 and 46 respectively; And one or more interface circuits 48, so that RBS is connected to BSC 30 with communication mode.Exemplary treatment circuit 40 comprises one or more signal processors, for example DSP circuit, microprocessor/microcontroller etc.; And relevant support circuit, and transceiver resources 42 comprises modulating/demodulating and the coding/decoding circuit that is used for realizing being used for the physical layer channel of communicating by letter with travelling carriage 12 on forward direction (transmissions) and reverse (reception) link.
According to one or more embodiment of the present invention, exemplary rate controlled can realize by being configured at BSC 30 and/or in 32 pairs of hardware of RBS, software or their any combination.For example, according to the present invention, the treatment circuit 40 that can comprise the RBS 32 of microprocessor resources as mentioned above can be configured to the rate controlled basic and that replenish that provides exemplary.In addition, can support at least some rate controlled to handle by the treatment circuit 34 that suitably disposes BSC 30 places.Shared processing between this BSC and the RBS can be especially suitable when BSC 30 handles or be provided for the information that rate controlled adjusts.
No matter this realization details, Fig. 3 has shown BSC 30 and the RBS 32 in the occasion that basic and auxiliary reverse link rate control is provided to travelling carriage 12.The basic rate control command also can be called the order of " substantially " rate controlled in this article, and auxiliary rate controlled order also can be called the order of " replenishing " rate controlled in this article.
Shown in travelling carriage 12 can receive the rate controlled order of Sector Range, with " substantially " rate controlled order, and the special speed of reception group as required control command, with " assisting " rate controlled order as it as it.A kind of alternative is, travelling carriage 12 can reception group special speed control command, with basic rate control command as it, and receiving mobile special speed control command as required, with " assisting " rate controlled order as it.As another kind of alternative, travelling carriage 12 can receive the rate controlled order of Sector Range, with basic rate control command as it, and receiving mobile special speed control command as required, with " assisting " rate controlled order as it.Certainly, this paper has considered other combination of basic/auxiliary rate controlled.
Consider that rate controlled order that travelling carriage 12 receives Sector Ranges is with the next example of basic reverse link rate control order as it, should be noted that the reverse link loading of the sector that the rate controlled order of these Sector Ranges can be operated just therein according to travelling carriage 12 generates.RBS 32 and/or BSC 30 can calculate sector load by the reception noise with increase in temperature of measuring base radio receiver place.Can adopt the alternative approach of measuring reverse link loading, for example by determine on the reverse link total throughout, monitoring user number and user type, whether discern in the sector quite a lot of usefulness and served fully per family etc.
Usually, for example, if the reverse link loading situation is high (measuring threshold value can be provided with respect to the base station probability that " is out of order ") with respect to one or more measurement threshold values, then public rate controlled order is generated as " downwards " order, and this will make travelling carriage 12 progressively adjust their speed downwards according to those orders.On the contrary, if load is light, then public rate controlled order is generated as " making progress " order, and in this case, travelling carriage 12 progressively adjusts upward their speed according to those orders.In fact, public rate controlled order is changing between the order up and down back and forth according to the load state that changes.
Be also noted that public rate controlled order can be generated as " load designator ", it can be called " reverse activity bit ".According to this rate controlled command generating method, the base station changes the one or more public rate controlled Command field bit that is sent, and with the reverse link loading situation of reflection variation, and travelling carriage 12 correspondingly is configured to handle these load designator.For example, travelling carriage 12 can be programmed the data transfer rate that increases them-according to radio condition and transmission power limit-receive indication in response to light reverse link loading; And reduce their data transfer rate-according to service request constraint etc.-receive indication in response to heavy reverse link loading.
With regard to basic rate control and auxiliary rate controlled, it is that certain is than low rate that the basic rate control command can be used for one group of user's speed " inhibition ", perhaps make this group keep current speed, and auxiliary rate controlled order is used for controlling as required some of them specific user's data transfer rate.For example, allow these specific users to realize High Data Rate according to their specific QoS needs.
For example, can distinguish the priority of supporting specific user or user's group, for example it be divided into gold/silver/copper data user.Therefore, the present invention can comprise the sector controlling mechanism of utilizing the configurable form/function that realizes this prioritization or can adopt basic rate control and assist rate controlled to distinguish the scheduling controlling algorithm of user priority order.In other scheme, basic/auxiliary rate controlled can be used for supporting having the different qos requirement of the different business example of the different business example on the travelling carriage 12 of a plurality of srvice instance.This travelling carriage 12 can provide feedback to reach high buffer level with indication, as the specific service instances of " watermark " level.These data allow to distinguish the order of the relative priority between each travelling carriage in the given sector together with power headroom feedback, feedback.
More than the flexible program of basic/auxiliary rate controlled and other something in common be, RBS 32 and/or BSC 30 can be configured to provide to travelling carriage 12 the first rate control command of continuous transmission, can be considered as and will not receive " default " rate controlled order of following under any auxiliary situation that surmounts order so that travelling carriage 12 receives.These default rate controlled orders are preferably pressed group or are shared by a plurality of travelling carriages 12 by the sector, though and nonessential shared these orders.
If the default rate control command is not enough to satisfy the quality of service requirement of specific travelling carriage 12, then send auxiliary rate controlled order as required.Therefore these auxiliary rate controlled orders provide " burst " rate control channel of the default rate control that can be used for surmounting on the travelling carriage 12 as required.
Description below is distributed to travelling carriage 12 so that the auxiliary rate controlled order of transmission can be based on the service request of travelling carriage 12 and/or the supervision of feedback are triggered with additional rate control channel.For example, travelling carriage 12 can be configured to provide buffer level feedback, and in this case, it sends the information of relevant its reverse link transmit queue to network 10.Therefore, the long trigger that distributes additional rate control channel that can be used as of transmit queue on the travelling carriage 12, and auxiliary rate control channel can be sent to travelling carriage 12, realizes than passing through the obtainable higher reverse link data rate of default rate control command to allow travelling carriage 12.
Certainly, explain that the feedback of other form and service request monitor that can be used for triggering as required auxiliary rate control channel distributes as the back, with satisfy travelling carriage specific and the group specific service quality require (QoS).Irrelevant with the special trigger mechanism that is adopted, Fig. 4 has shown the exemplary processing logic that is used to manage basic and auxiliary rate control channel distribution.
Processing is from distributing to basic rate control channel " " (step 100) with specific travelling carriage 12.Notice that therefore the rate control channel that this primary channel is preferably shared can carry the public rate controlled order of the radio sector that travelling carriage 12 operates just therein, perhaps can carry given group the group special speed control command that travelling carriage 12 is assigned to.Notice that the group rate controlled can be used for based on class of subscriber, as gold, silver, the copper user waits that Differentiated Services is provided.
Such as in the application of common unsettled being entitled as incorporated herein " Generalized Rate Control forWireless Communication Network " (SN 10/755104) detailed description, the basic rate control channel can time division multiplexing on one other channel.For example, in network based on cdma2000, the public rate control channel of one or more forward directions (F-CRCCH) can be multiplexed on the Forward Common Power Control Channel (F-CPCCH), F-CPCCH generally comprises multiplexed power control bit (PCB), is used for a plurality of travelling carriages 12 of correspondence are carried out power control.For example, the rate controlled order is multiplexed on the power control channel can perhaps replaces rate control information based on will not replacing with the rate controlled bit with the power bit based on regularly deleting section one or more power control bits.
Under any circumstance, in case travelling carriage 12 is distributed to the basic rate control channel, then the ongoing service request to travelling carriage 12 monitors, whether is enough to satisfy the reverse link service request (step 104) of travelling carriage 12 to judge the basic rate control command.Fig. 5 has shown the feedback mechanism of multiple travelling carriage to the base station, and wherein one or more are used in to assess in logic temporarily travelling carriage 12 to be distributed to assists rate control channel whether rational basis is arranged.This feedback includes but not limited to status indicator, reverse link rate request, transmission buffer queue information and transmit power headroom information.
State indication from travelling carriage 12 can be used for indicating travelling carriage 12 needs to increase its reverse link data rate, and rate request can be used for asking clearly the reverse link rate change by travelling carriage 12.Equally, sending buffer queue information can be sent by travelling carriage 12, with as current reverse link throughput for its whether enough indication.Here, buffer level information can be quantized, so that save bit.For example, empty to full available for example two or three bit quantizations of buffer status successive range (continuum), so that many-valued buffer level designator to be provided to the base station.Alternatively or additionally, travelling carriage 12 can send the transmit power headroom indication to the base station, and wherein, this information can be used for judging that travelling carriage 12 is current whether has available enough reservation transmitting powers, so that with higher reverse link data rate work.
In addition, under the situation of a plurality of srvice instance of operation, can generate the arbitrary example in the described multi-service example or the quantification buffer level information of all examples at travelling carriage 12.The quantification buffer level of multi-service example can send in a report, perhaps sends in continuous report when needed.
Whether therefore any and all this information can be used for assessing needs auxiliary temporarily rate controlled to satisfy the reverse link service request (step 106) of travelling carriage 12.If determine to need auxiliary rate controlled, then travelling carriage is distributed to auxiliary rate control channel (step 108), and on this auxiliary channel, will be replenished the rate controlled order subsequently and send to travelling carriage 12 (step 110).Assist command can require according to the certain quality of service of travelling carriage 12 to generate.
In case distributed auxiliary channel, just can monitoring traffic situation/requirement, to judge whether should and when discharging auxiliary rate control channel (step 112).For example, as long as the queue level of travelling carriage 12 surpasses defined threshold, needs only the higher reverse link rate of its continuation requirement etc., just can keep auxiliary rate control channel for travelling carriage 12.Certainly, be used to keep or discharge assist the logic of rate control channel also to depend on more senior consideration, whether for example total reverse link loading, any other travelling carriage 12 or some groups of travelling carriages 12 have higher service priority etc.
No longer need (or requirement) auxiliary rate controlled in case determine travelling carriage 12, then discharge auxiliary rate control channel and distribute (step 114).After discharging auxiliary rate control channel, the reverse link rate control that provides on the basic rate control channel is provided travelling carriage 12.Note, to assist the rate controlled order to offer under the situation of some groups of target MSs 12, the decision that discharges auxiliary rate controlled order can all no longer need to assist the rate controlled order to satisfy the judgement of their service needed based on any one travelling carriage 12 in institute's speed group.
Should be noted that travelling carriage 12 generally can be configured to make the auxiliary rate controlled order that receives can surmount the basic rate control command that receives fully.That is to say that according to the exemplary embodiments of above processing logic, the basic rate control command continues, except any auxiliary rate controlled order that is receiving, also can continue to receive the basic rate control command.Therefore, given travelling carriage 12 can special configuration be followed this order during assisting the rate controlled order in reception, and only just follows the basic rate control command when assisting rate controlled.Perhaps, travelling carriage 12 can be configured to: if receive auxiliary rate controlled order, just revise their responses to the basic rate control command based on these orders.In a kind of method in back, therefore basic rate control that provides on basic rate control channel and the auxiliary rate control channel and certain logical combination of assisting rate controlled will be provided the effective speed control on the given travelling carriage 12.
Above information is mentioned, and basic rate control channel and auxiliary rate control channel can form the multiplexed subchannel on the Common Power Control Channel for example.Therefore, send first (substantially) rate controlled order of sharing by one group of travelling carriage 12 on the basic subchannel of the public rate controlled of forward direction (F-CRCFSCH) that RBS 32/BSC30 can define on F-CPCCH.
Then, for the every group of travelling carriage 12 or the specific travelling carriage 12 of the auxiliary rate controlled of needs, RBS32/BSC30 can replenish subchannel (F-CRCSSCH) in the public rate controlled of the forward direction of correspondence and go up the order of transmission second (replenishing) rate controlled.These auxiliary rate control channels are sent to second rate command its corresponding mobile station 12 or its corresponding some groups of travelling carriages 12 separately, and they also can be multiplexed on the Common Power Control Channel.Under the situation of using a plurality of Common Power Control Channels, can transmit different basic rate control and assist rate controlled on each channel therein as required.
Other channel also can be used for providing creative basic/auxiliary rate controlled.For example, RBS 32/BSC 30 can utilize given forward grant channel (F-GCH) to provide shared basic rate control command to one group of given travelling carriage 12.Then, it can utilize any amount of the 2nd other F-GCH to come target MS or some groups of target MSs in them in those travelling carriages 12 that auxiliary rate controlled order is provided.In this occasion, and in other occasion, should be appreciated that the rate controlled order can include but not limited to clear and definite speed permission or incremental up/down commands.In addition, to belong to same type be unnecessary for basic rate control command and auxiliary rate controlled order.For example, given group basic rate control command can be clear and definite permission, and the auxiliary rate controlled order that sends to the target member of this group can be generated as incremental up/down commands or be generated as clear and definite grant commands.
In any case, it should be appreciated by those skilled in the art that the present invention passes through the temporary transient distribution of auxiliary rate controlled, solved the needs that satisfy the burst qos requirement on the target MS 12 as required substantially, and can utilize various basic/auxiliary channel realizes.In any case the present invention at least temporarily can not send additional rate controlled order by those travelling carriages 12 that the public rate controlled order that is sending is satisfied by preferably limiting to the reverse link service request, thereby has reduced signaling consumption.
Therefore, the invention is not restricted to above-mentioned exemplary details, and not limited by accompanying drawing.In fact, the present invention is only limited by following claim and lawful equivalent thereof.
