Abstract
The invention discloses a resource allocation method and network-side equipment. The method comprises the following steps that: a network side judges whether the size of a data packet transmitted by a user side during a talkspurt period is in a stable status when determining that voiceover internet protocol (VoIP) service transmission enters the talkspurt period; the network side determines a lower limit value of the data packet transmitted by the user side during the talkspurt period according to the size of the data packet in the stable status after the size of the data packet is confirmed to be in the stable status; and the network side adopts a semi-continuous resource scheduling mode to allocate a semi-continuous resource to the user side when the following VoIP service is in the talkspurt period, wherein the semi-continuous resource is not greater than the determined lower limit value. By controlling the size of the semi-continuous resource, the report of unnecessary data volume in a buffer area is avoided, so the report expenditures on a buffer status report (BSR) and a scheduling request (SR) are effectively reduced, and the communication resources are saved.
Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of resource allocation methods and user's side and report the method for BSR and user side equipment, network equipment.
Background technology
In mobile communication system, network side will be dispatched and the resource distribution the upstream data bag of user terminal UE, just need to know the situation of UE buffer area outgoing data amount on this up logic channel, this just needs UE to report the data volume situation in own buffer area, namely carrying out BSR (Buffer StatusReport, buffer status report) reports.When UE does not have uplink shared resources to send BSR, need to apply for uplink shared resources by network side, sending SR (Scheduling Request, dispatch request), by network side, be that UE distributes the transmission of uplink shared resources for BSR.The BSR reported in the above described manner is called to Regular BSR, namely only has Regular BSR can trigger SR and report.
The trigger condition that Regular BSR reports has following three kinds, and wherein any one trigger condition is set up and all can be triggered Regular BSR and report:
1) when having the data higher than the data priority in current cache district to arrive;
2) when the upper buffer area of all LCG (Logic Channel Group, logic channel group) be all empty, and when new data arrival is arranged;
When 3) the overtime and buffering area of buffer memory report retransmission timer also has data to upload.Wherein retransmission timer is restarted after reporting BSR each time, if after overtime, buffering area has data, triggers BSR and reports.
Speech business is the basic research content of radio communication, only there is PS territory (Packet SwitchedDomain, packet-switched domain) in system, LTE system for example, speech business is by VoIP (Voiceover Internet Protoco1) carrying.The VoIP business model as shown in Figure 1, the speech coder of user's side is by fixed cycle output packet, the data transmission state of VoIP business mainly is divided into active period (talkspurt) and quiet period (silent period), at active period, the packet time interval of exporting is fixed as 20ms, in quiet period, the packet time interval of exporting is fixed as 160ms.The data transmission state of VoIP business also is included in the VoIP business and sets up rear transient state (transient state), and the packet that transient state is exported does not carry out the head compression, and the packet time interval of output is fixed as 20ms, and the transient state duration is very short.
For the VoIP business, the packet of active period is greater than the packet of quiet period, and in the time of in being in respectively active period and quiet period, the excursion of packet is very little.Take and adopt transmission rate to be example as the user side equipment of the AMR of 12.2kbps, because the packet of transient state does not carry out the head compression, packet is larger, is 92byte, after transient state, the packet of active period is the speech business packet that has carried out the head compression, and data package size is 35～47byte.In quiet period, there is no the speech business transfer of data, SID (Silence Indicate Date, the reticent designation data) bag only produced due to background noise, SID bag size is 10～22byte.
For the VOIP business data packet, periodically arrive, the relatively-stationary characteristics of data package size, LTE grid side is used semi-continuous scheduling to the packet of active period transmission, and the SID bag of quiet period transmission and the retransmission data packet may of makeing mistakes are adopted to dynamic dispatching.Be illustrated in figure 2 the resource distribution mode schematic diagram of network side for the VoIP business data packet, concrete mode is as follows:
1) to the packet of active period, the network side interval persistent resources cycle is distributed the up semi-continuous resource of fixed size for user's side, the wherein said persistent resources cycle is 20ms, thus user's side at activator appliance, periodically to use network side be the up semi-continuous resource transmission packet of its distribution.In prior art, this resource distribution mode is called to semi-continuous source scheduling mode.
2) when determining while by active period, transferring quiet period to, network side discharges up semi-continuous resource, for the SID bag of quiet period, after receiving the BSR that user's side reports at every turn, according to the BSR received, distribute PRB (Physical Resource Block, Physical Resource Block) resource for user's side; , for the packet of transient state, be wherein also for user's side, to distribute ascending resource according to the BSR received.In prior art, will become the dynamic dispatching mode according to the mode that the BSR received is user's side Resources allocation.
3) for the packet of VOIP activation of service phase re-transmission and the SID bag of quiet period re-transmission, report because re-transmission can trigger BSR, the mode of all using dynamic dispatching is that it distributes the PRB resource.
According to current regular BSR trigger condition, if the resource distribution mode adopted can make user's side before next packet arrives, that one of front Packet Generation is successful, user's side buffering area is empty, when next number arrives according to bag, triggers BSR and reports.In the situation that adopt semi-continuous source scheduling mode to distribute semi-continuous resource (the oval part comprised in Fig. 2), the size of existing semi-continuous resource of distributing is larger than active period packet, therefore user's side can transfer each active period packet in 20ms, and every 20ms all needs to trigger a BSR and reports during semi-continuous scheduling of resource.Network side due to the allocation of packets that will transmit for user's side semi-continuous resource, and enough this data packet transmission of the semi-continuous resource of distributing are complete, do not need to receive BSR and the SR for the VoIP business data packet, for the BSR received, report also and can not process, caused unnecessary expense.
Therefore utilize existing source scheduling mode, for adopting semi-continuous source scheduling mode to distribute the VoIP business of semi-continuous resource, still can trigger frequently BSR and report, and BSR reports and can trigger SR and report, this will cause existing following problem:
1) unnecessary BSR reports and has caused taking a large amount of PUSCH (Physical Uplink SharedChannel, the physical uplink sharing channel) resource, unnecessary SR reports and has caused taking a large amount of ascending control channel PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) resource.Be easy to cause the interior PUCCH of system and PUSCH resource-constrained.
2) because BSR dispatches with resource and distributes by up dynamic dispatching, BSR reports triggering SR to report, network side reports and just need to utilize PDCCH (Physical Downlink Control Channel according to the BSR of the every scheduling of SR reported, Physical Downlink Control Channel) to user's side, send a dispatch, so unnecessary BSR reports, also can waste a large amount of PDCCH resources, cause PDCCH resource-constrained.
3) report continually BSR can cause reporting the SR there is no need, be unfavorable for saving power for terminal, the interference of PUCCH is strengthened.
Existing source scheduling mode causes having the resource-constrained of above several respects, has limited the number of users that can hold in the communication system.Under equal userbase, can reduce the service quality of business in network.

Embodiment
The method that resource allocation methods the present invention proposed below in conjunction with drawings and Examples and user's side report BSR and user side equipment, network equipment illustrate in greater detail.
Resource allocation methods provided by the invention, for user's side VoIP business, transmit, can reduce that unnecessary buffer area data volume reports is that BSR reports, be specially when adopting the semi-continuous scheduling mode, control by the semi-continuous resource size to distributing, can during the semi-continuous scheduling mode, avoid row buffer frequently for empty, according to existing BSR trigger mechanism, can avoid unnecessary BSR to report and reported by the SR of its triggering, thereby effectively reducing unnecessary BSR reports expense and SR to report expense, improved whole capacity of communication system, reduced the PUCCH interference, also make user's power saving effect better.
As shown in Figure 3, according to the resource allocation methods provided in embodiments of the invention, comprise:
Step S301, network side determine when user's side VoIP business transmission enters active period, judges whether the data package size that user's side activating phase transmits is in stable state;
After user's side is set up the VoIP business, can think and enter active period, fluctuate within the specific limits but generally after of short duration transient state, enter the data package size transmitted, be called data package size and be in stable state.When transient state, the packet received is the packet that does not carry out the head compression, therefore packet is larger, when the data package size transmitted is in stable state, what network side received is the packet after the head compression, therefore, can determine whether to be in stable state by the variation that receives packet.
Step S302, determining that while being in stable state, network side, according to the data package size that is in stable state, is determined the lower limit of the packet that user's side activating phase transmits;
When entering active period and starting to transmit the packet after the head compression, the size variation of packet is little, according to prior art, can according to first information through a compressed data packets received, determine the lower limit of the packet that user's side activating phase transmits, detailed process repeats no more here.
Step S303, during the VoIP business transmission active period of determining after being in stable state, network side adopts semi-continuous source scheduling mode to distribute semi-continuous resource for user's side, and the semi-continuous resource of distributing is not more than the lower limit of determined packet.Above-mentioned semi-continuous source scheduling mode refers to the resource distribution mode of interval persistent resources cycle for the semi-continuous resource of user's side distribution.
After determining and entering stable state, adopt semi-continuous source scheduling mode, in the present embodiment, control the lower limit that the semi-continuous resource of distributing slightly is not more than user's side activating phase packet, the data volume that can transmit of the interval persistent resources cycle semi-continuous resource of distributing can be less than the size of user's side buffer area packet usually like this, buffering area can not become sky at every turn after the upstream data bag being transmitted like this, just the variation of buffer area data volume from the sky to the non-NULL can not occur frequently so during semi-continuous scheduling, thereby solved the problem that up RegularBSR frequently reports.Do not report the demand of BSR, naturally just need not report SR request uplink shared resources yet.
The present invention has fully taken into account the characteristics of VoIP business, the buffer area data volume masked during most semi-continuous schedulings reports, valuable PUCCH, PUSCH and PDCCH resource have been saved, can make wireless communication system under the equivalent network environment for more user provides high-quality service, meanwhile the power saving effect of terminal is also better.
Specifically ask situation for two kinds that below provide semi-continuous source scheduling mode in step S303:
The semi-continuous resource of 1) distributing equals the lower limit of determined active period packet size
The packet size of transmitting due to user's side activating phase generally can be less than this down values, therefore, after user's side once is greater than the data packet transmission of this size, just has data in user's side buffer memory, can not cause BSR frequently to report.
Method 2: the semi-continuous resource of distributing is slightly less than the lower limit of determined active period packet size
Under this method of salary distribution, user's side enters the semi-continuous resource transmission packet that utilizes network side to distribute after active period, in buffer memory, has the probability of data larger, therefore more can not cause BSR frequently to report.
The control mode of the semi-continuous resource size of distributing under double persistent resources scheduling mode during concrete enforcement is not limited to this; will be understood that; so long as by the control of double persistent resources size; protection scope of the present invention makes to have in user's side transmission data pack buffer district the resource distribution mode of data, within all should be dropped on.As the scope that allows of the lower limit that is greater than the active period packet size etc., no longer exhaustive here.
Due in the original allocation half-persistence scheduling resources, the data volume of up transmission is fixing, if control the lower limit that the semi-continuous resource of distributing is not more than determined packet, the data volume that can transmit due to semi-continuous resource is slightly less than the size of terminal buffers district packet, so after a period of time, data volume in up buffer area can increase gradually, thus generally the active period duration more in short-term, can not affect laser propagation effect.For long sight of some active period times, after a period of time, data volume in up buffer area can increase gradually, due to the semi-continuous resource of distributing, be equal to or slightly less than the size of terminal buffers district packet, likely cause the accumulation of packet to cause the packet of follow-up arrival not transmitted in time, thereby increased the time delay of packet, this is little on the not high VoIP business transmission impact of requirement of real-time.For the higher VoIP business of requirement of real-time, preferably, during the transmission of VoIP business is in active period, also comprise step in the present embodiment:
Step S304, the buffer status report BSR according to the user's side interval received reports, determine the data quantity C in user's side buffer memory
bsr, user's side reports the cycle interval greater than user's side activating phase generation packet of BSR;
In the present embodiment, for user's side, during the transmission of VoIP business is in active period, interval reporting buffer status report BSR, and report the cycle interval greater than user's side activating phase generation packet of BSR, specifically can determine the time interval according to the transmission situation.Preferably, user's side reports BSR to adopt following two kinds of modes:
Mode one: when the transmission of user's side VoIP business is in active period, interval setting cycle T
bsrWhile defining the uplink shared resources of transmission BSR, carry out BSR and report, wherein setting cycle is greater than the cycle that user's side activating phase produces packet.Wherein, for user's side, if the resource that network side distributes can not all pass data all in buffer memory, preferentially report BSR, remaining resource is for passing data.
Mode two: when the transmission of user's side VoIP business was in active period, the interval re-transmission period was determined in buffer memory when data are arranged, and determines whether the uplink shared resources of transmission BSR, and described re-transmission period is greater than the cycle that user's side activating phase produces packet;
If the uplink shared resources of transmission BSR is arranged, user's side is directly carried out BSR and is reported; Wherein, for user's side, if the resource that network side distributes can not all pass data all in buffer memory, preferentially report BSR, remaining resource is for passing data.
If nothing, at first reporting scheduling request SR, and the uplink shared resources that utilizes network side to distribute according to SR carries out BSR and reports.
While as the mode adopting retransmission timer, reporting BSR, its re-transmission period is much larger than the active period packet output cycle.
Step S305, when determined data volume is greater than the Second Threshold of setting, i.e. C
bsr>=C
Threshold2, adopt the dynamic dispatching mode to carry out the first resource distribution for user's side.
Adopt aforesaid way, in conjunction with dynamic dispatching, this situation of time delay for data volume accumulation in user's side buffer area causes, can adopt periodic BSR to report mechanism to solve this problem on the basis of semi-continuous resource.If the data volume in BSR indication buffer memory surpasses a certain thresholding, will trigger dynamic dispatching so, the packet of buffer area is sent by dynamic dispatching, thereby solve the problem that the buffer area data are accumulated.Meet the VoIP business transmission requirement that real-time is high.
In addition, while in step S305, dispatching, the resource of distributing equals the data volume in user's side buffer memory, like this user's side after carrying out this time dynamic dispatching, cumulative data no longer in buffer memory.It is C that the resource of perhaps, distributing is slightly less than buffer data size
bsr, the data volume that the resource of namely distributing can be dispatched is C
bsr-C
Δ, C
ΔFor the data volume that need to stay in buffer memory after dynamic dispatching.
Step S306, after completing this time Dynamic Resource Allocation for Multimedia, continue to adopt semi-continuous source scheduling mode to distribute semi-continuous resource for user's side.
Scheme according to the present embodiment, if adopted semi-continuous scheduling to be aided with the mode of dynamic dispatching, in semi-continuous scheduling and resource between allotment period, user's side will report with the length of cycle BSR timer BSR or report BSR with the length that retransmits the BSR timer, the length of these two timers will, much larger than the report cycle of 20ms, greatly reduce expense.
In quiet period, terminal adopts Regular BSR reporting uplink buffer area data volume.The SID bag of quiet period and the voice packet of active period are very different, the packet of quiet period is smaller, the time interval that packet arrives is larger (as 160ms) again, so the packet that the data volume in the buffer memory reported by BSR can be told in up buffer area is that SID wraps or VoP.In the present embodiment, in step S301, network side determines that the transmission of user's side VoIP business enters active period, specifically comprises:
According to user's side, set up the buffer status reporting BSR reported after the VoIP business, determine data volume S in user's side buffer memory
bsr
Determined data volume is greater than the first threshold S of setting
Threshold1The time, i.e. S
bsr>=S
Threshold1, determine that the transmission of user's side VoIP business has proceeded to and entered active period from quiet period.If business is set up the initial stage, experience of short duration transient state and enter stable state, and use the dynamic dispatching mode to transmit first VoP, if proceed to active period from quiet period, directly enter stable state.
In the present embodiment, in step S301, network side judges that whether the data package size that user's side activating phase transmits is in stable state, specifically comprises:
Network side receives packet can be separated and obtain corresponding packet at different layers, at the PDCP layer, can know the size of PDCP PDU (Protocol Data Unit, protocol Data Unit), at rlc layer, can know the size of RLC PDU.Therefore can at the packet that packet data convergence protocol PDCP separates, be PDCP PDU size according to the packet received, judge whether the data package size that user's side activating phase transmits is in stable state.
Or at the packet that radio link layer RLC separates, be RLC PDU (Protocol Data Unit) size according to the packet according to receiving, judge whether the data package size that user's side activating phase transmits is in stable state.
Or data volume in user's side buffer memory of the BSR reported according to user's side reflection, judge whether the data package size that user's side activating phase transmits is in stable state.
By in above-mentioned three kinds of modes any, the size of the packet that can obtain receiving, according to the number range of active period packet, if the data package size obtained in active period packet numerical value scope, thinks whether the data package size that user's side activating phase transmits is in stable state.
In another embodiment of the present invention, the resource allocation methods provided is compared with above-described embodiment, also comprise that the BSR reported according to the user's side interval received carries out the step of dynamically adjusting to the semi-continuous resource size of distributing in half persistent resources scheduling mode, be specially:
During the transmission of VoIP business was in active period, network side was determined the data quantity C in user's side buffer memory according to the BSR received
bsrBe greater than the 3rd threshold value C
Threshold3The time, illustrate that semi-continuous resource distribution is very few, trigger the forward adjustment that persistent resources is distributed, the adjustment amount size is Δ
1, and adjust the lower limit that later half persistent resources is not more than the active period packet.Preferably, during adjustment, adopt the dynamic dispatching mode to carry out the first resource distribution for user's side, the problem of piling up to alleviate user's side buffer memory.
If network side is determined the time interval of double reception BSR, be not more than user's side activating phase while producing two times of cycle of packet, the semi-continuous resource that distribution is described as the double BSR of reporting in active period 40ms is too much, need negative sense to adjust the size of semi-continuous resource, the adjustment amount size is Δ
2.
In the above embodiment of the present invention, provided the resource distribution mode entered before active period finishes to active period from determining, in an embodiment more of the present invention, in the above on the basis of embodiment, provide the VoIP business and transmit the resource distribution mode in other period, preferably, after network side determines that user's side is set up the VoIP business, before the transmission of user's side VoIP business entered active period, the BSR employing dynamic dispatching mode reported according to user's side was user's side Resources allocation.After network side determined that the transmission of user's side VoIP business enters active period, before the data package size transmitted in user's side activating phase was in stable state, the BSR employing dynamic dispatching mode reported according to user's side was user's side Resources allocation.Network side discharges the semi-continuous resource of distributing after determining that the transmission of user's side VoIP business proceeds to quiet period by active period; In quiet period, it is user's side Resources allocation that the BSR that network side reports according to the user's side received adopts the dynamic dispatching mode.
When being ready for sending the last part of voice packet, the data volume of leaving in user's side buffer memory can be less than the data volume that semi-continuous resource can be transmitted, and after this is transmitted, buffer memory will be sky.In the present embodiment, determine that the transmission of user's side VoIP business proceeds to quiet period specifically in the following way by active period: when network side detects during the semi-continuous scheduling mode, user's side is when N continuous time sends empty packet on semi-continuous resource, determine and by active period, proceed to quiet period by user's side, can discharge semi-continuous resource.After entering quiet period, each SID bag is by the dynamic dispatching Resources allocation.
The method of user's side reporting buffer status report BSR a kind of also is provided in the present embodiment, has comprised:
During the transmission of VoIP business was in active period, the interval setting cycle reported BSR, setting cycle to be greater than the cycle that user's side activating phase produces packet while defining the uplink shared resources that transmits BSR.Wherein, for user's side, if the resource that network side distributes can not all pass data all in buffer memory, preferentially report BSR, remaining resource is for passing data.
In the present embodiment, also provide another kind of user's side to report the method for BSR, as shown in Figure 4, having comprised:
Step S401, during the transmission of VoIP business was in active period, the interval re-transmission period was determined in buffer memory when data are arranged, and determines whether the uplink shared resources of transmission BSR, if having, execution step S402, as nothing, execution step S403; Wherein above-mentioned re-transmission period is greater than the cycle that user's side activating phase produces packet;
Step S402, user's side is directly carried out BSR and is reported; Wherein, for user's side, if the resource that network side distributes can not all pass data all in buffer memory, preferentially report BSR, remaining resource is for passing data.
Step S403, at first reporting scheduling request SR, and the uplink shared resources that utilizes network side to distribute according to SR carries out BSR and reports.
The LTE system transmission rate of below take illustrates that as the 12.2k speech business as example resource allocation methods of the present invention and user's side report the detailed process of BSR.As shown in Figure 5, main process is as follows:
After step S501, network side determined that user's side is set up the VoIP business, before the transmission of VoIP business entered active period, the BSR employing dynamic dispatching mode reported according to user's side was user's side Resources allocation.
After step S502, network side determined that the transmission of user's side VoIP business enters active period, before the data package size transmitted in user's side activating phase was in stable state, the BSR employing dynamic dispatching mode reported according to user's side was user's side Resources allocation;
Step S503, network side is determined when user's side VoIP business transmission enters data package size that active period and user's side activating phase transmit and is in stable state, according to the data package size that is in stable state, determine the lower limit of the packet that user's side activating phase transmits, adopt semi-continuous source scheduling mode to distribute semi-continuous resource for user's side, described semi-continuous resource is not more than determined described lower limit.
Step S504, the BSR that reception user's side interval reports also determines the data volume in user's side buffer memory;
Step S505, when determined data volume is greater than the Second Threshold of setting, adopt the dynamic dispatching mode to carry out the first resource distribution for user's side; Continue afterwards to adopt semi-continuous source scheduling mode to distribute semi-continuous resource for user's side;
When step S506, network side determined that according to the BSR received data volume in user's side buffer memory is greater than the 3rd threshold value, forward was adjusted the size of described semi-continuous resource, and adjusted later half persistent resources and be not more than described lower limit.Preferably adopt the dynamic dispatching mode to carry out the first resource distribution.
Step S507, determine time interval of double reception BSR, is not more than user's side activating phase while producing two times of cycle of packet, and negative sense is adjusted the size of described semi-continuous resource.
Wherein the step of step S505, S506 and S507, without sequencing, as long as satisfy condition, is adjusted accordingly and dispatches.
Step S508, when network side detects during the semi-continuous scheduling mode, user's side when N continuous time sends empty packet on semi-continuous resource, is determined and by active period, is proceeded to quiet period by user's side;
Step S509, discharge semi-continuous resource, and each SID bag is by the dynamic dispatching Resources allocation.
