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 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 resource allocation the upstream data bag of user terminal UE, just need know the situation of UE buffer area outgoing data amount on this up logic channel, this just needs UE that the data volume situation in the own buffer area is reported, promptly carrying out BSR (Buffer StatusReport, buffer status report) reports.When UE does not have up shared resource to send BSR, need to apply for up shared resource by sending SR (Scheduling Request, dispatch request) to network side, be that UE distributes up shared resource to be used for the transmission of BSR by network side.The BSR that reports in the above described manner is called Regular BSR, promptly has only 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 the data higher than the data priority in the current cache district arrives;
2) all be empty when all LCG (Logic Channel Group, logic channel group) go up buffer area, 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 overtime back buffering area has data, then triggers BSR and reports.
Speech business is the basic research content of radio communication, in the system that only has PS territory (Packet SwitchedDomain, packet-switched domain), and 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 side is by fixed cycle dateout bag, 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 being exported is fixed as 20ms, in quiet period, the packet time interval of being exported is fixed as 160ms.The data transmission state of VoIP business also is included in the professional back transient state (transient state) of setting up of VoIP, 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 active period and quiet period respectively, the excursion of packet is very little.To adopt transmission rate is that the user side equipment of the AMR of 12.2kbps is an example, because the packet of transient state does not carry out the head compression, packet is bigger, is 92byte, the packet of active period is the speech business packet that has carried out the head compression after the transient state, and the packet size is 35～47byte.Do not have the speech business transfer of data in quiet period, have only because the SID (Silence Indicate Date, reticent designation data) that background noise produces wraps, SID bag size is 10～22byte.
Periodically arrive at the VOIP business data packet, the relatively-stationary characteristics of packet size, LTE grid side is used semi-continuous scheduling to the active period data packets for transmission, and the SID bag of quiet period transmission and the retransmission data packet may of makeing mistakes are adopted dynamic dispatching.Be illustrated in figure 2 as the resource distribution mode schematic diagram of network side at the VoIP business data packet, concrete mode is as follows:
1) to the packet of active period, the persistent resources cycle is the up semi-continuous resource that user side distributes fixed size to network side at interval, the wherein said persistent resources cycle is 20ms, thus user side periodically to use network side at activator appliance be the up semi-continuous resource transmission packet of its distribution.In the prior art this resource distribution mode is called semi-continuous scheduling of resource mode.
2) when determining to transfer quiet period to by active period, network side discharges up semi-continuous resource, for the SID of quiet period bag, receive the BSR that user side reports at every turn after, according to the BSR that receives is that user side distributes PRB (Physical Resource Block, Physical Resource Block) resource; Wherein for the packet of transient state, also be to be that user side distributes ascending resource according to the BSR that receives.The mode that in the prior art will be the user side Resources allocation according to the BSR of reception becomes the dynamic dispatching mode.
3) for the packet of VOIP activation of service phase re-transmission and the SID bag of quiet period re-transmission, because re-transmission can trigger BSR and report, the mode of all using dynamic dispatching is that it distributes the PRB resource.
According to present regular BSR trigger condition, if the resource distribution mode that adopts can make user side before next packet arrives the packet in front be sent successfully, then the user side buffering area is empty, when next number arrives according to bag, triggers BSR and reports.Distributed under the situation of semi-continuous resource (the oval part that comprises among Fig. 2) in the semi-continuous scheduling of resource mode of employing, the size of existing semi-continuous resource of being distributed is bigger than active period packet, therefore user side can transmit each active period packet in 20ms, and then every 20ms all needs to trigger a BSR and reports during semi-continuous scheduling of resource.Network side has distributed semi-continuous resource owing to want data packets for transmission for user side, and enough this data packet transmission of the semi-continuous resource of distributing are intact, do not need to receive BSR and SR at the VoIP business data packet, report also for the BSR that receives and can not handle, caused unnecessary spending.
Therefore utilize the existing resources scheduling mode, for adopting semi-continuous scheduling of resource mode to distribute the VoIP business of semi-continuous resource, triggering BSR that still can be frequent reports, and BSR reports and can trigger SR and report, and 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 in the system PUCCH and PUSCH resource-constrained.
2) dispatch and resource allocation by up dynamic dispatching owing to BSR, BSR reports triggering SR to report, network side reports with regard to needs according to the BSR of the every scheduling of SR that reports and utilizes PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) sends a dispatch to user side, also can waste a large amount of PDCCH resources so unnecessary BSR reports, cause PDCCH resource-constrained.
3) report BSR can cause reporting the SR that there is no need continually, be unfavorable for the terminal power saving, the interference of PUCCH is strengthened.
The existing resources 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 service quality professional in the network.

Embodiment
Method that resource allocation methods that the present invention is proposed below in conjunction with drawings and Examples and user side report BSR and user side equipment, network equipment illustrate in greater detail.
Resource allocation methods provided by the invention, for the professional transmission of user side VoIP, can reduce that unnecessary buffer area data volume reports is that BSR reports, be specially when adopting the semi-continuous scheduling mode, by control to the semi-continuous resource size of being distributed, can avoid row buffer during the semi-continuous scheduling mode frequently for empty, according to existing BSR trigger mechanism, can avoid unnecessary BSR to report and reported by the SR of its triggering, thereby having effectively reduced unnecessary BSR reports expense and SR to report expense, improved the whole communication system capacity, reduced the PUCCH interference, also made user's power saving effect better.
As shown in Figure 3, comprise according to the resource allocation methods that is provided in the embodiments of the invention:
When step S301, network side determine that the professional transmission of user side VoIP enters active period, judge whether user side active period institute data packets for transmission size is in stable state;
After user side is set up the VoIP business, can think to enter active period, fluctuate within the specific limits, be called the packet size and be in stable state but generally after of short duration transient state, enter institute's data packets for transmission size.When transient state, the packet that receives is not carry out a compressed data packet, therefore packet is bigger, when institute's data packets for transmission size is in stable state, network side receives is packet after the head compression, therefore, can determine whether to be in stable state by the variation that receives packet.
Step S302, when determining to be in stable state, network side is determined the lower limit of user side active period institute data packets for transmission according to the packet size that is in stable state;
When entering active period and beginning to transmit packet after head compression, the size variation of packet is little, according to prior art, can determine the lower limit of user side active period institute data packets for transmission according to first the information that receives through a compressed data packets, detailed process repeats no more here.
Step S303, during the professional transmission of the VoIP after determining the to be in stable state active period, it is that user side distributes semi-continuous resource that network side adopts semi-continuous scheduling of resource mode, the semi-continuous resource of being distributed is not more than the lower limit of determined packet.Above-mentioned semi-continuous scheduling of resource mode is meant that the persistent resources cycle is the resource distribution mode that user side distributes semi-continuous resource at interval.
After determining to enter stable state; adopt semi-continuous scheduling of resource mode; the semi-continuous resource of Control Allocation slightly is not more than the lower limit of user side active period packet in the present embodiment; so at interval the persistent resources cycle semi-continuous resource of being distributed can data quantity transmitted usually can be less than the size of user side buffer area packet; 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 take place frequently, thereby solved the problem that up RegularBSR frequently reports so during semi-continuous scheduling.Do not report the demand of BSR, just need not report SR to ask up shared resource naturally yet.
The present invention has fully taken into account the VoIP business features, the buffer area data volume that has 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 services, meanwhile the power saving effect of terminal is also better.
Specifically ask situation for two kinds that provide semi-continuous scheduling of resource mode among the step S303 below:
1) the semi-continuous resource of being distributed equals the lower limit of determined active period packet size
Because therefore user side active period institute data packets for transmission size generally can, after user side carries out once the data packet transmission greater than this size, just have data less than this down values in the user side buffer memory, can not cause frequent BSR to report.
Method 2: the semi-continuous resource of being distributed is slightly less than the lower limit of determined active period packet size
Under this method of salary distribution, user side enters the semi-continuous resource transmission packet that utilizes network side to distribute behind the active period, has the probability of data bigger in the buffer memory, therefore more can not cause frequent BSR to report.
The control mode of double following semi-continuous resource size of being distributed of persistent resources scheduling mode is not limited thereto during concrete enforcement; will be understood that; so long as pass through the control of double persistent resources size; make the resource distribution mode that data are arranged in the user side transmits data packets buffer area, all should drop within protection scope of the present invention.As greater than scope that lower limit allowed of active period packet size etc., no longer exhaustive here.
Because in the original allocation half-persistence scheduling resources, the data volume of up transmission is fixing, if the semi-continuous resource of Control Allocation is not more than the lower limit of determined packet, because semi-continuous resource can data quantity transmitted be slightly less than the size of terminal buffers district packet, so after a period of time, data volume in the up buffer area can increase gradually, thus generally the active period duration more in short-term, can not influence laser propagation effect.For long sight of some active period times, after a period of time, data volume in the up buffer area can increase gradually, because the semi-continuous resource of distributing is equal to or slightly less than the size of terminal buffers district packet, might cause the accumulation of packet to cause the packet of follow-up arrival in time not transmitted, thereby increased the time delay of packet, this is little to the professional transmission influence of the less demanding VoIP of real-time.Require than higher VoIP business for real-time, preferably, during the professional transmission of VoIP is in active period, also comprise step in the present embodiment:
Step S304, the buffer status report BSR according to the user side that receives reports at interval determines the data quantity C in the user side buffer memory
Bsr, user side reports the cycle interval greater than user side active period generation packet of BSR;
In the present embodiment, for user side, during the professional transmission of VoIP is in active period, report buffer status report BSR at interval, and report the cycle of BSR, specifically can determine the time interval according to the transmission situation interval greater than user side active period generation packet.Preferably, user side reports BSR to adopt following dual mode:
Mode one: when the professional transmission of user side VoIP is in active period, interval setting cycle T
BsrWhen defining the up shared resource of transmission BSR, carry out BSR and report, wherein setting cycle produces the cycle of packet greater than the user side active period.Wherein for user side, if the resource that network side distributes can not all pass data all in the buffer memory, then preferentially report BSR, remaining resource is used to pass data.
Mode two: when the professional transmission of user side VoIP is in active period, when re-transmission period is determined in the buffer memory data to be arranged at interval, determine whether the up shared resource of transmission BSR, described re-transmission period produces the cycle of packet greater than the user side active period;
If the up shared resource of transmission BSR is arranged, user side directly carries out BSR and reports; Wherein for user side, if the resource that network side distributes can not all pass data all in the buffer memory, then preferentially report BSR, remaining resource is used to pass data.
If do not have, reporting scheduling request SR at first, and utilize network side to carry out BSR according to the up shared resource that SR distributed to report.
As when the mode that adopts retransmission timer reports BSR, its re-transmission period is much larger than the active period packet output cycle.
Step S305, determined data volume is during greater than second threshold value set, i.e. C
Bsr〉=C
Threshold2, adopting the dynamic dispatching mode is that user side carries out the first resource distribution.
Adopt aforesaid way, in conjunction with dynamic dispatching, this situation of time delay at data volume accumulation in the user 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 the 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.Satisfy the professional transmission requirement of the high VoIP of real-time.
In addition, when dispatching in step S305, the resource of being distributed equals the data volume in the user side buffer memory, like this user side after carrying out this time dynamic dispatching, cumulative data no longer in the buffer memory.Perhaps, to be slightly less than buffer data size be C to the resource of being distributed
Bsr, promptly the data volume that can dispatch of the resource of being distributed is C
Bsr-C
Δ, C
ΔBe the data volume that need in buffer memory, stay after the dynamic dispatching.
Step S306, finish this time Dynamic Resource Allocation for Multimedia after, continue adopting semi-continuous scheduling of resource mode is that user side distributes semi-continuous resource.
Scheme according to present embodiment, if adopted semi-continuous scheduling to be aided with the mode of dynamic dispatching, then during semi-continuous scheduling and resource allocation, user side will report BSR with the length of cycle BSR timer or report BSR with the length that retransmits the BSR timer, the length of these two timers will greatly reduce expense much larger than the report cycle of 20ms.
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 bigger again (as 160ms) that packet arrives is so the packet that the data volume in the buffer memory that reports by BSR can be told in the up buffer area is that SID wraps or VoP.In the present embodiment, in step S301, network side determines that the professional transmission of user side VoIP enters active period, specifically comprises:
Set up the buffer status reporting BSR that reports after the VoIP business according to user side, determine data volume S in the user side buffer memory
Bsr
Determined data volume is greater than the first threshold S that sets
Threshold1The time, i.e. S
Bsr〉=S
Threshold1, determine that the professional transmission of user side VoIP has changed over to from quiet period to enter active 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 change active period over to, then directly enter stable state from quiet period.
In the present embodiment, in step S301, network side judges that whether user side active period institute data packets for transmission size is in stable state, specifically comprises:
Network side receives packet can be separated at different layers and obtain corresponding packet, can know the size of PDCP PDU (Protocol Data Unit, protocol Data Unit) at the PDCP layer, can know the size of RLC PDU at rlc layer.Therefore can be PDCP PDU size at the packet that packet data convergence protocol PDCP separates according to the packet that receives, judge whether user side active period institute data packets for transmission size is in stable state.
Or, judge whether user side active period institute data packets for transmission size is in stable state according to being RLC PDU (Protocol Data Unit) size at the packet that radio link layer RLC separates according to the packet that receives.
Or data volume in the user side buffer memory of the BSR that reports according to user side reflection, judge whether user side active period institute data packets for transmission size 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 packet size that obtains thinks then whether user side active period institute data packets for transmission size is in stable state in active period packet numerical value scope.
In another embodiment of the present invention, the resource allocation methods that is provided is compared with the foregoing description, also comprise the step that the BSR that reports at interval according to the user side that receives dynamically adjusts the semi-continuous resource size of being distributed in the half persistent resources scheduling mode, be specially:
The professional transmission of VoIP is in during the active period, and network side is determined data quantity C in the user side buffer memory according to the BSR that receives
BsrGreater than the 3rd threshold value C
Threshold3The time, illustrate that semi-continuous resource allocation is very few, then trigger the forward adjustment that persistent resources is distributed, the adjustment amount size is a Δ
1, and adjust the lower limit that later half persistent resources is not more than the active period packet.Preferably, adopting the dynamic dispatching mode during adjustment is that user side carries out the first resource distribution, to alleviate the problem that the user side buffer memory is piled up.
If network side is determined the time interval of double reception BSR, when being not more than the user side active period and producing two times of cycle of packet, the semi-continuous resource that distribution then 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 a Δ
2
In the above embodiment of the present invention, provided from determining to enter the resource distribution mode before active period finishes to active period, in an embodiment more of the present invention, in the above on the basis of embodiment, provide the professional transmission of the VoIP resource distribution mode in other period, preferably, after network side determines that user side is set up the VoIP business, before the professional transmission of user side VoIP entered active period, the BSR employing dynamic dispatching mode that reports according to user side was the user side Resources allocation.After network side determined that the professional transmission of user side VoIP enters active period, before user side active period institute data packets for transmission size was in stable state, the BSR employing dynamic dispatching mode that reports according to user side was the user side Resources allocation.Network side discharges the semi-continuous resource of being distributed after determining that the professional transmission of user side VoIP changes quiet period over to by active period; In quiet period, it is the user side Resources allocation that the BSR that network side reports according to the user side that receives adopts the dynamic dispatching mode.
When being ready for sending the last part of voice packet, the data volume of leaving in the user side buffer memory can data quantity transmitted less than semi-continuous resource, and after this transmission is finished, buffer memory will be sky.Determine in the present embodiment that the professional transmission of user side VoIP changes quiet period over to specifically in the following way by active period: when network side detects during the semi-continuous scheduling mode, during the empty packet of the inferior transmission of user side N continuous on semi-continuous resource, determine to change quiet period over to by active period, then can discharge semi-continuous resource by user side.After entering quiet period, each SID bag is all by the dynamic dispatching Resources allocation.
Also provide a kind of user side to report the method for buffer status report BSR in the present embodiment, having comprised:
During the professional transmission of VoIP is in active period, report BSR when setting cycle defines the up shared resource of transmission BSR at interval, setting cycle produces the cycle of packet greater than the user side active period.Wherein for user side, if the resource that network side distributes can not all pass data all in the buffer memory, then preferentially report BSR, remaining resource is used to pass data.
The method that also provides another kind of user side to report BSR in the present embodiment as shown in Figure 4, comprising:
Step S401 during the professional transmission of VoIP is in active period, when re-transmission period is determined in the buffer memory data to be arranged at interval, determines whether the up shared resource of transmission BSR, if having, execution in step S402 is not as there being execution in step S403; Wherein above-mentioned re-transmission period produces the cycle of packet greater than the user side active period;
Step S402, user side directly carry out BSR and report; Wherein for user side, if the resource that network side distributes can not all pass data all in the buffer memory, then preferentially report BSR, remaining resource is used to pass data.
Step S403, reporting scheduling request SR at first, and utilize network side to carry out BSR according to the up shared resource that SR distributed to report.
Be that the 12.2k speech business is the detailed process that example explanation resource allocation methods of the present invention and user side report BSR with LTE system transmissions speed below.As shown in Figure 5, main process is as follows:
After step S501, network side determined that user side is set up the VoIP business, before the professional transmission of VoIP entered active period, the BSR employing dynamic dispatching mode that reports according to user side was the user side Resources allocation.
After step S502, network side determined that the professional transmission of user side VoIP enters active period, before user side active period institute data packets for transmission size was in stable state, the BSR employing dynamic dispatching mode that reports according to user side was the user side Resources allocation;
Step S503, network side determines that the professional transmission of user side VoIP enters active period and user side active period institute data packets for transmission size when being in stable state, according to the packet size that is in stable state, determine the lower limit of user side active period institute data packets for transmission, adopting semi-continuous scheduling of resource mode is that user side distributes semi-continuous resource, and described semi-continuous resource is not more than determined described lower limit.
Step S504, the data volume in the BSR that the reception user side reports at interval and the definite user side buffer memory;
Step S505, determined data volume is during greater than second threshold value set, and adopting the dynamic dispatching mode is that user side carries out first resource and distributes; Continuing afterwards to adopt semi-continuous scheduling of resource mode is that user side distributes semi-continuous resource;
When step S506, network side determined that according to the BSR that receives data volume in the user 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.The preferred dynamic dispatching mode that adopts is carried out the first resource distribution.
Step S507 determines time interval of double reception BSR, and when being not more than the user side active period and producing two times of cycle of packet, negative sense is adjusted the size of described semi-continuous resource.
Wherein the step of step S505, S506 and S507 does not have sequencing, as long as satisfy condition, then adjusts accordingly and dispatches.
Step S508 when network side detects during the semi-continuous scheduling mode, during the empty packet of the inferior transmission of user side N continuous on semi-continuous resource, determines to change quiet period by user side over to by active period;
Step S509 discharges semi-continuous resource, and each SID bag is all by the dynamic dispatching Resources allocation.
