Description
Technical field
The present invention relates to WCDMA (Wideband Code Division Multiple Access (WCDMA)) wireless network, refer to the transport format combination selecting method of code combination transmission channel in a kind of WCDMA RNC (radio network controller) system especially.
Background technology
Transformat combination (TFC, Transport Format Combination) selecting is media interviews control (MAC, Media Access Control) critical function of protocol layer, the purpose of this function is: at downlink transmission direction, momentary rate and transmission channel priority according to transport channel data stream, the information such as load state of current air interface, in the transmission format composite set (TFCS) of L3 configuration, for each transmission channel is selected suitable transformat (TF, Transport Format) and in the mode of transformat indication (TFI, Transport Format Indicator) notify L1.The selected TFI of each transmission channel combines the TFC that forms in the TFCS of L3 configuration.
For each transmission channel, a Transmission Time Interval (TTI) is all arranged, in its Transmission Time Interval (TTI), there is a transformat (TF).Transmission Time Interval (TTI) is an attribute of transformat, is that the speed etc. according to transmission channel is configured by high level.Transformat has write down two variablees: transmission block size and transmission block number, can represent the speed that this transmission channel is supported with transformat.For a transmission channel, several TF can be arranged, these TF constitute the transmission format set TFS of transmission channel.Carry out multiplexingly when number of transmission channels, when being combined into code combination transmission channel (CCTrCH, CodedComposite Transport Channel), in a certain TTI, the TF of these transmission channels has just constituted transformat combination TFC.The set of CCTrCH TFC constitutes transmission format composite set TFCS.
The TFC of transmission channel selects to occur in the minimum TTI place of all transmission channels of forming CCTrCH, and the MAC protocol stack carries out TFC and selects according to the TFCS that L3 distributes.
As shown in Figure 1, be the exchanges data schematic diagram of MAC layer with layer 1.Transmission channel 1～3 expression is the composition situation of different transmission channel TF among the figure, has three kinds.Wherein X-axis is a time shaft, and the part between two arrows is represented the size of Transmission Time Interval.The situation of transmission channel 1 expression is that the number of transmission block is constant, all be 1, and the size of transmission block changes, and is inequality at each Transmission Time Interval; What transmission channel 2 was represented is that situation is the number of transmission block and all variable situation of size of transmission block, and this situation is the most complicated; The third situation is represented is that the size of transmission block is fixed, and what change in each Transmission Time Interval is the number of transmission block.In the composition of these three kinds transmission TF, the third situation is the easiest control, also is we carry out the basis that TFC selects.
It is that the Common transport channel of high priority at first carries out TF and selects that the MAC protocol stack carries out principle that TFC selects.Therefore judge that at first how many data the transmission channel of high priority has to send out, if have then according to the data number that will send, select its TF, this TF as restrictive condition, from the TFCS set, satisfy TFC subclass of TFC composition that this TF of this high priority transfer channel selects.The TF that carries out the transmission channel of time priority then selects, according to the data cached number that can send out in this transmission channel this moment, from the TFC subclass that chose just now, select a suitable TF, then according to the new TF that selects, the TFC subclass that the new TF that satisfies these two transmission channels selects of from the TFC subclass, getting back.The transmission channel that takes second place again of processing priority then, such process is performed until all transmission channels and all obtains handling, and obtains a TFCI at last, is the combination of all selected TFI.
Other has a restrictive condition, as a moment that the sends data TTI that is not some transmission channel in the time of cycle, according to the action period of TFI in the agreement, the TFI that the TFI of these transmission channels adopts at this previous delivery time, like this when carrying out the TFC selection, at first to from the TFCS set of L3 configuration, obtain a subclass TFCS subset (TFCS subclass) these unalterable TFI as restrictive condition.And then from this TFCS subset, select according to the principle of priority.
TFC system of selection of the prior art is not considered from entire system; When network takes place will have a negative impact to power when congested, can not satisfy the demand of RNC system to power.
Summary of the invention
The invention provides the transport format combination selecting method of code combination transmission channel in a kind of WCDMA of the being applicable to RNC system,, satisfy the RNC system well power demand when network takes place to increase congested control when congested on the basis that existing TFC selects.
The inventive method comprises the following steps:
1) at Transmission Time Interval (TTI) due in, signaling channel is selected a TFI according to the data number of waiting in the channel buffer to send out from the TFS of this channel, and in the TFCS set that L3 distributes, the TFC that satisfies this TFI selection is formed a TFC subclass;
2) non-BE Traffic Channel in a described TFC subclass, is selected a TFI according to the packet size of data number in the buffer or Service Data Unit, and the TFC that satisfies this TFI selection in the TFC subclass is formed the 2nd TFC subclass;
3) the BE Traffic Channel detects network and whether is in congestion state or relieve congestion state, if congestion state then changes step 4 over to when carrying out the transformat selection; If the relieve congestion state then changes step 5 over to; Otherwise, change step 6 over to;
4) this BE Traffic Channel is current TFS multiply by a speed limit coefficient, obtains the TFS of a speed limit, in the TFS of this speed limit, select one be not more than and near buffer in the TFI of data block number, change step 7 over to;
5) maximum TFI increases by 1 among the TFS that this BE Traffic Channel is current, generates a new TFS, in this new TFS one of selection be not more than and near buffer in the TFI of data block number, change step 7 over to;
6) in the 2nd TFC subclass, select one be not more than and near buffer in the TFI of data block number, change step 7 over to;
7) this TTI TFC selection course constantly of the whole code combination transmission channel of end.
According to said method, described step 3 comprises:
When network takes place to make the RRM module of RNC send congestion notification message to MACD when congested, carry described speed limit coefficient and speed limit interval time parameter in this congestion notification message; MACD is after receiving this congestion notification message, and the state of oneself is set to congestion state;
The BE Traffic Channel is when carrying out the transformat selection, and whether the operating state that detects this MACD is congestion state.
Described speed limit is set to the integral multiple of described TTI blanking time.
According to said method, described step 3 also comprises:
When network congestion was removed, the RRM module was sent relieve congestion message to MACD, carried the recovery interval time parameter in this relieve congestion message; MACD is after receiving this relieve congestion message, and the state of oneself is set to the relieve congestion state;
The BE Traffic Channel is when carrying out the transformat selection, and whether the operating state that detects this MACD is the relieve congestion state.
When the operating state that detects MACD is the relieve congestion state, whether described step 5: detecting the current TFS of this BE channel is the TFS of L3 initial configuration if further comprising, if not, TFI maximum among then that this BE Traffic Channel is the current TFS increases by 1, generate a new TFS, in this new TFS, carry out TFI and select; Otherwise, change step 6 over to.
The described integral multiple that recovers to be set to blanking time described TTI.
Transmission Time Interval described in the said method (TTI) due in is the minimum TTI place of all channels of forming the code combination transmission channel.
Because the cell power of RNC system needs steadily, if the sub-district is under the state of high capacity, the data burst of BE business, the perhaps a large number of users existence of possible factor such as moving toward cell edge, descending power may be in unsettled high level.This sudden to cause the soaring of cell power be huge, forms the overload phenomenon easily, will inevitably influence the stability of system.Use the inventive method,, reduce power, satisfy the demand of RNC system, help improving the ability of whole system stable operation power stability when network takes place the TFC that selects to be carried out speed limit handle when congested.

Embodiment
The principle that the MAC protocol stack carries out the TFC selection is the moment that arrives at Transmission Time Interval, the selectable priority of transmission channel of high priority in code combination transmission channel, just select according to the order of transmission channel priority, each transmission channel selects own transformat to indicate (TFI), and TFI that will the transmission channel higher than own priority selected in same code combination transmission channel is as the restrictive condition of oneself selection.The combination of the TFI that all transmission channels of a code combination transmission channel are selected, the TFCI that final exactly this code combination transmission channel is selected constantly at this Transmission Time Interval.At next Transmission Time Interval constantly, the code combination transmission channel can carry out this process once more, selects this TFCI constantly.The life cycle of TFCI is exactly a Transmission Time Interval.
Follow the thought of agreement, need distribute different priority for the transmission channel of bearer service and signaling, and the type of service of channel be the access request decision of mobile terminal device according to the situation of business.According to agreement, the transmission channel of carrier signaling (comprising RRC signaling and high-level signaling) has the highest priority, and business is divided into the professional and professional two big classes of BE (Best Effort) of non-BE (Best Effort, transmission as possible).Non-Best Effort business, comprised CS (Circuit Switching, Circuit Service) professional and PS (the Packet Switching in territory, Packet Service) the session service class (Conversational) in territory, stream service class (Streaming) business, because its requirement to time delay has higher transmission priority.Best Effort business mainly comprises PS territory interactive traffic class (Interactive) and background service class (Background) business, only when also having remaining bandwidth, channel just transmits for Best Effort class business, less demanding to time delay is so they have minimum transmission priority.
The implication of the TFI representative of transmission channel is the speed of transmission channel, in the time of the third transmission mode among employing Fig. 1, in transmission course, the size of each transmission block is fixed, and the just number of transmission block that changes, and reach control to speed with this, that is to say that transmission rate is that number with transmission block is directly proportional, so TFI can reduced representation becomes the product of the size of the number of transmission block and transmission block.And further TFI and transmission block number can be mapped, make TFI and transmission block number also be directly proportional, then Zui Da TFI also just represents maximum transmission block number, just Zui Da speed.
Each transmission channel all has a transmission format set TFS, it is the set of the TFI of this transmission channel configuration, at each Transmission Time Interval constantly, transmission channel can be according to the data volume in the transmission channel buffer and other transmission restrictive conditions, select a suitable TFI, just a suitable speed sends data.
For CS territory business, its data rate is controlled by high level, and MACD (media interviews control private part) can not change.The transmission block size is not fixed among the TFS of CS business, the transformat of transmission channel is corresponding to a kind of size and number of transmission block, the high level data bag of CS business is a form that TFI represents among the TFS, MACD need select a TFI according to the size of the packet of MACD SDU (Service Data Unit, Service Data Unit).Specifically be exactly that MACD compares the size of SDU and each transformat among piece number and the TFS, the TFI identical with this SDU form is selected.
For PS territory business, the transmission block size is fixed among its TFS, satisfies the third situation of the said Fig. 1 in front.The TFC selection of MAC protocol stack is the type of service according to channel bearing, and according to the data number in the transmission channel buffer, according to the proportional relation of TFI and data block number, the TFI of the maximum of rate requirement and don't waste bandwidth is satisfied in selection.Specifically be relatively, select one and be not more than the data block number of the data block number in the buffer memory and each TFI correspondence, and near the available TFI of data block number in the buffer memory.Here the implication that available TFI represents is the influence because of the TFI selection of other transmission channel in the code combination transmission channel, and causing the TFS that can select is the subclass of the TFS of original high-rise L3 configuration.
The TFC selection algorithm of MAC of the present invention is in a code combination transmission channel, and to the principle of each transmission channel according to the front, the TFI that carries out transmission channel selects, and finally obtains the TFCI of this code combination transmission channel.Promptly at first satisfy the transmission requirement of signaling data, signaling data is at first carried out TF according to current speed select, non-then Best Effort Traffic Channel is carried out TF and is selected according to packet size and the speed of current MACD-SDU.At this moment just obtain a TFC subset (subclass), this subclass is among the TFCS of high-rise L3 configuration, obtains according to the restriction of the transmission channel of having selected TFI.The TF of BestEffort Traffic Channel selects and carry out in this subclass.
If the number of users that inserts in the sub-district increases,, start congested control with regard to needs like this and carry out quick load control perhaps because the traffic bursts of BE business may cause cell load sharply to rise abruptly, and load is exacerbated to the quality that influences communication.Because the BE business is low for delay requirement, if reduce the speed of this class business, congestion situation can be alleviated to a certain extent.So,, can select carry out speed limit to the TF of BE Traffic Channel and handle when network takes place when congested.
The present invention selects to carry out the speed limit processing to the TF of BE Traffic Channel, and its detailed process is as follows:
Open the public-measurement algorithm switch of the RRM module of RNC, then NODEB will measure the transmitting power of sub-district, periodic report RNC public-measurement message.If the carrier transmit power of sub-district is greater than some thresholding and satisfy sluggish condition, then can send congested message to RNC; If NODEB detects and congestedly do not exist, then send relieve congestion message to RNC.When RNC receives congestion messages, the RRM module is sent congestion notification message to MACD, indicate congested generation, MACD is after receiving congestion notification message, the state of oneself is set to congestion state, and according to the speed limit time interval parameter of speed limit coefficient in the message and setting, the cycle is reduced transmission rate then, wait until that always the RRM module receives the relieve congestion message of NODEB, till MACD sends relieve congestion message.MACD will progressively recover original transmission rate according to the recovery interval time parameter in the relieve congestion message then.
Concrete steps are: after MACD receives congestion notification message, the state that oneself is set is a congestion state, and according to the speed limit blanking time of speed limit coefficient (as: 0.5) that has in this congestion notification message and setting, in each blanking time (be the integral multiple of the minimum TTI of transmission channel this blanking time), (initial TFS is exactly the TFS of high-rise initial configuration to multiply by current available TFS with the speed limit coefficient, next blanking time then with the TFS after the last time speed limit as current TFS), obtain up-to-date available TFS.Described speed limit coefficient is determined by the RRM module, it is an attribute of sub-district, can be configured at the user terminal of Back Administration Module, its span is greater than 0, less than 1, like this, the transmission block number of the maximum TFI representative among the TFS that at every turn obtains is inevitable more and more littler, and it is more and more littler also just to be equivalent to speed.
Handle through above-mentioned speed limit, when the BE Traffic Channel is carried out the TF selection,, be optimized among the available TFS after speed limit and select by from the TFS of high level configuration, selecting in the agreement, make speed change, can effectively alleviate the congestion situation of system along with the congestion situation of system.
The RRM module is in relieve congestion, send relieve congestion message to MACD, then MACD can enter the relieve congestion state, at each TTI constantly, whether the TFS that MACD detects this BE channel has returned to the TFS of original initial configuration fully, if then MACD can finish the relieve congestion state, enters normal condition; Otherwise MACD increases by 1 with TFI maximum among the now available TFS, generates new available TFS.Increase progressively because the TFI among the TFS is an order, and TFI is directly proportional with speed, like this, the selectable TFI maximum of MACD is increase just, and corresponding speed also can increase.
If MACD receives high-rise congested indication again at congestion state, then the MACD speed limit interval time parameter of using new speed limit coefficient and setting is proceeded speed limit and is handled; If MACD when the state of relieve congestion is received a congested indication again, then ends the relieve congestion state, reenter congestion state, the above-mentioned congested control procedure of recuperation.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
