Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
Fig. 1 is a kind of flow diagram of resource regulating method in one embodiment of the invention, as shown in Figure 1, this implementation
The executive agent of example is base station, and described method includes following steps：
S1：After terminal UE or base station initiating business request, base station is according to UE buffer status report BSR reported and described
The cache information of base station determines the channel resource demand of uplink and/or downlink.
Wherein, it is described according to 36.321 6.1.3 chapters and sections of 3GPP TS, buffer status report (Buffer Status
Report, abbreviation BSR) MAC cache size of the message for logic channel group (LCG, Logic Channel Group) carrying 6bit
(Buffer Size identify the index of 64 kinds of values altogether) characterizes the size of Current MAC layers data to be sent.
Specifically, RRC (Radio Resource Control, wireless heterogeneous networks) connections are established, and UE or base station
After initiating business request, UE reports BSR to base station, base station then according to the BSR that UE is reported determine uplink channel resource demand (by
UE is sent to the channel resource needed for base station), and according to the cache information of base station in itself determine downlink channel resource demand (by
Base station is sent to the channel resource needed for UE), so that it is determined that uplink and downlink service resources demand.
S2：When the resource of the serving cell of the UE can not meet the channel resource demand, base station is according on described
The channel resource demand of row and/or downlink, ascending resource cell, downlink resource cell or peers are switched to by the UE
Cell.
Wherein, the ascending resource cell is configured for ascending time slot more than descending time slot and ascending time slot is matched with descending time slot
The difference put be more than or equal to predetermined threshold value adjacent area, the downlink resource cell for descending time slot more than ascending time slot be configured and under
The difference of row time slot and ascending time slot configuration is more than or equal to the adjacent area of predetermined threshold value, the peers cell for ascending time slot with
The difference of descending time slot configuration is less than the adjacent area of predetermined threshold value.
Specifically, when the resource of the serving cell of the UE can not meet the channel resource demand, base station then root
UE is switched into corresponding adjacent area according to the channel resource demand of the uplink and/or downlink：Specifically, when this business is uploads
Based on business, such as hair wechat circle of friends, send the mail with attachment, then in a manner that cell meets and shares, by UE points
It is fitted on the ascending resource cell based on ascending time slot；When this business be download based on business, such as download, Online Video,
Then in a manner that cell meets and shares, UE is assigned to the downlink resource cell based on descending time slot；When this business is upper
The business for carrying equity, such as VoLTE voice communications, video calling are descended, then by way of cell load sharing, UE is distributed
To the peers cell of uplink and downlink timeslot equity.
It can be seen that the present embodiment is the dispatching method based on " resource pool ", " resource pool " refers to the money except serving cell
Outside source is scheduled, scheduling of resource range is also included in adjacent area by algorithm.
Therefore, before above-mentioned steps S1, also need the partly or entirely adjacent area of three types following to serving cell configuration and
Measure thresholding：
1) downlink resource cell：LTE TDD cells descending time slot is more than the cell of ascending time slot configuration, is suitble to downlink business
Based on UE be resident；Configurable A5_DL thresholdings, after UE meets this A5 thresholding, are switched to the adjacent area.Such as when the down channel of UE
After resource requirement reaches the A5_DL thresholdings, it is switched to the adjacent area.
2) ascending resource cell：LTE TDD cells ascending time slot is more than the cell of descending time slot configuration, is suitble to uplink service
Based on UE be resident；A5_UL thresholdings are configured, after UE meets this A5 thresholding, are switched to the adjacent area.Such as when the up channel of UE provides
After source demand reaches the A5_UL thresholdings, it is switched to the adjacent area.
3) peers cell：The cell that the configuration of LTE TDD cells uplink and downlink timeslot is not much different, is suitble to uplink and downlink countermeasure
The UE of business is resident；A5_BL thresholdings are configured, after UE meets this A5 thresholding, are switched to the adjacent area.Such as when the uplink and downlink channel of UE
After resource requirement reaches the A5_BL thresholdings, it is switched to the adjacent area.
In the present embodiment, the type belonging to adjacent area is determined by the ascending time slot proportioning of cell.According to 3GPP TS36.211
4.2 chapters and sections describe, and LTE TDD systems uplink and downlink timeslot proportioning division methods, it is that ascending resource is small that agreement time slot proportion, which is 0,
Area；1st, 6 be peers cell；2nd, 3,4,5 be downlink resource cell.Cell type concordance list is as shown in table 1.
Table 1：Adjacent area Type division table corresponding with time slot proportion
Wherein, D represents ascending time slot, and U represents downlink, and S represents converted slot.Then as can be seen from Table 1, ascending resource is small
The ascending time slot in area is more than descending time slot and the two number differences are more than or equal to 3, the ascending resource cell for being 0 such as time slot proportion
Ascending time slot quantity is 6, and descending time slot quantity is 2；The descending time slot of downlink resource cell is more than ascending time slot and the two quantity
Difference is more than or equal to 3, if the descending time slot quantity for the downlink resource cell that time slot proportion is 2 is 6, ascending time slot quantity is 2, when
The descending time slot quantity for the downlink resource cell that gap proportioning is 3 is 6, ascending time slot quantity is 3, and the downlink that time slot proportion is 4 provides
The descending time slot quantity of cell-of-origin is 7, ascending time slot quantity is 2, and time slot proportion is the descending time slot number of 5 downlink resource cell
It is 1 to measure as 8, ascending time slot quantity；The ascending time slot and descending time slot of peers cell are not much different, and the two number differences are small
In 3, the ascending time slot such as the peers cell that time slot proportion is 1 is equal with descending time slot quantity, and pair that time slot proportion is 6
Etc. resources cell ascending time slot quantity for 5, descending time slot quantity is 3, and the two quantity difference is 2, i.e. uplink and downlink timeslot quantity
It is not much different.
It can be seen that the present embodiment judges business uplink and/or downlink according to UE and the data buffer storage state report of base station
Channel resource demand, and when the resource of the serving cell in the UE can not meet the channel resource demand, base station according to
The UE is switched to ascending resource cell, downlink resource cell or right by the channel resource demand of the uplink and/or downlink
Etc. resources cell.In this way, business characteristic of the present embodiment according to UE, demand of the real-time judgment to resource, are reconfigured by RRC
UE is dispatched to appropriate cell by mode, realizes the rapidly and efficiently scheduling of resource, the differentiation scheduling based on business demand, and
Realize the maximization that need satisfaction is perceived using maximization, user of Internet resources.
In an alternate embodiment of the present invention where, as shown in Fig. 2, after above-mentioned steps S1, the method further include as
Lower step：
S3：When the resource of the serving cell of the UE disclosure satisfy that the channel resource demand, the base station is to described
UE sends RRC reconfiguration messages, to distribute the local resource of the serving cell to the UE.
Specifically, uplink and/or down channel resources determined by step S1 be disclosure satisfy that in the resource of serving cell
During demand, channel resource adjustment can be completed by RRC reconfiguration courses in serving cell, distributed in serving cell for UE
Resource.
It can be seen that business characteristic of the present embodiment according to UE, demand of the real-time judgment to resource, are reconfigured by RRC
Mode, UE is dispatched to appropriate cell (serving cell or adjacent area), realize resource rapidly and efficiently scheduling, based on business need
The differentiation scheduling asked, and realize the maximization that need satisfaction is perceived using maximization, user of Internet resources.
Resource regulating method in above-described embodiment is divided into two processes：Resource requirement calculating process and resource adjusted
Journey.Detailed description is expanded with regard to two processes below：
In an alternate embodiment of the present invention where, above-mentioned steps S1 specifically may include following sub-step：
S11：The base station determines that uplink caches byte, and according to the cache information of the base station according to the BSR that UE is reported
Determine down buffer storage byte.
S12：When the uplink caches byte and/or the down buffer storage byte more than the preset caching upper limit, the base
Triggering channel of standing increases adjustment.
S13：When the uplink caches byte and/or the down buffer storage byte less than preset caching lower limit, the base
Triggering channel of standing reduces adjustment.
Specifically, as shown in figure 3, according to the Buffer Size indexes of BSR message, the byte of MAC cachings is calculated
Number BUFFER_MAC_xL.Wherein, UE is reported BSR mark uplink caching byte BUFFER_MAC_UL, under the BSR marks of base station
Row caching byte BUFFER_MAC_UL.
Correspondingly, when uplink and/or down buffer storage surpass the upper limit, i.e. BUFFER_MAC_xL>During BUFFER_MAC_MAX_xL,
Then triggering channel increases adjustment (CHANNEL_ADD processes)；When uplink and/or down buffer storage are less than limit, i.e. BUFFER_MAC_xL
<During BUFFER_MAC_MIN_xL, then trigger channel and reduce adjustment (CHANNEL_DEC processes).
Further, in an alternate embodiment of the present invention where, above-mentioned steps S3 is specifically included：
S31：When the base station triggers channel is reduced and adjusted, the base station sends RRC reconfiguration messages to the UE, with
The channel for completing the UE reduces adjustment.
Specifically, the adjustment of channel resource reduction is completed in serving cell by RRC reconfiguration courses, specific signaling
As shown in Figures 4 and 5, base station issues RRC reconfiguration messages (RRC Connection Reconfiguration) completion for interaction
Channel in cell reduces adjustment：
I) base station issues RRC connection reconfigurations and puts message (RRC Connection Reconfiguration), completes UE's
Channel, which subtracts, matches；
Ii) UE, which is received, subtracts with after instruction, if successfully completing channel adjustment, replys RRC connection reconfigurations and puts and complete message
(RRC Connection Reconfiguration Complete), as shown in Figure 4.
Iii it) if UE channel adjustments fail, is rebuild by RRC and completes link repair, and reply RRC connection reconstruction message
(RRC Connection Re-establishmen) message, as shown in Figure 5.
S32：When the base station triggers channel increases and adjusts, if the ascending resource of the serving cell and/or downlink money
Source disclosure satisfy that the channel resource demand, and the base station sends RRC reconfiguration messages to the UE, to complete the letter of the UE
Road increases adjustment.
Specifically, channel resource increases the preferential trial of adjustment and is completed in serving cell, if the resource energy of serving cell
Enough meeting channel resource increases adjustment, then increases adjustment of the process with the reduction (CHANNEL_DEC) in above-mentioned steps S31, leads to
It crosses RRC and reconfigures completion.
It can be seen that the resource of the serving cell of the UE disclosure satisfy that the channel resource demand in two kinds of situation：When
When triggering channel reduction adjustment, the resource of serving cell disclosure satisfy that the channel resource demand certainly；When triggering channel increases
Preferential to attempt to complete in serving cell during adjustment, the resource of serving cell may can meet the channel resource demand.
Further, if this cell uplink and/or downlink resource are insufficient, the resource distribution adjustment between triggering cell, on
Step S2 is stated, is specifically included：
S21：When the base station triggers channel increases and adjusts, if the ascending resource of the serving cell and/or downlink money
Source can not meet the channel resource demand, and the ascending physical signal resource block PRB utilization rates of the serving cell are more than preset
First utilization threshold and downlink PRB utilization rates are more than preset second utilization threshold, and the base station sends the to the UE
One A5 measures control message, so that the UE is switched to peers cell by triggering A5 events.
Specifically, when the ascending physical signal resource block PRB utilization rates of serving cell are more than preset first utilization threshold
And downlink PRB utilization rates are more than preset second utilization threshold, then show the uplink and downlink resource of resource of serving cell not
Channel resource demand can be met, then need UE switching to peers cell.
S22：If the uplink PRB utilization rates are more than first utilization threshold and the downlink PRB utilization rates are less than
Equal to second utilization threshold, the base station sends the 2nd A5 to the UE and measures control message, so that the UE passes through
Triggering A5 events are switched to ascending resource cell.
Specifically, when the uplink PRB utilization rates are more than first utilization threshold and the downlink PRB utilization rates
Less than or equal to second utilization threshold, then channel resource need cannot be met by showing the ascending resource of the resource of serving cell
It asks, then needs UE switching to ascending resource cell.
S22：If the downlink PRB utilization rates are more than second utilization threshold and the uplink PRB utilization rates are less than
Equal to first utilization threshold, the base station sends the 3rd A5 to the UE and measures control message, so that the UE passes through
Triggering A5 events are switched to downlink resource cell.
Specifically, when the downlink PRB utilization rates are more than second utilization threshold and the uplink PRB utilization rates
Less than or equal to first utilization threshold, then channel resource need cannot be met by showing the downlink resource of the resource of serving cell
It asks, then needs UE switching to downlink resource cell.
Specifically, Fig. 6 is the signaling diagram of the present embodiment medium and small interval scheduling of resource process, as shown in fig. 6, minizone resource
Scheduling process is specific as follows：
(1) if " serving cell uplink PRB utilization rates>PRBUtilLimitUL (preset first utilization threshold) " or
" downlink PRB utilization rates>PRBUtilLimitDL (preset second utilization threshold) ", then base station is put by RRC connection reconfigurations
(RRC Connection Configuration Reconfiguration) message measures control message, tool to UE configurations A5
Body includes three kinds of situations：
If i) " serving cell uplink PRB utilization rates>PRBUtilLimitUL " and " downlink PRB utilization rates>
PRBUtilLimitDL " issues A5_BL and measures control message (the first A5 measures control message), attempts to switch to peers
Cell.
Ii) if " serving cell uplink PRB utilization rates>PRBUtilLimitUL " and " downlink PRB utilization rates≤
PRBUtilLimitDL " issues A5_UL and measures control message (the 2nd A5 measures control message), attempts to switch to ascending resource
Cell.
Iii) if " serving cell downlink PRB utilization rates>PRBUtilLimitDL " and " uplink PRB utilization rates>
PRBUtilLimitUL " issues A5_DL and measures control message (the 3rd A5 measures control message), attempts to switch to downlink resource
Cell.
(2) after UE receives measurement control message, RRC connection reconfigurations is replied and put completion message (RRC Connection
Configuration Reconfiguration Complete), and start A5 measurements.
(3) after UE completes nearby region measurement, reporting measurement reports (Measurement Report), to be closed to base station report
Suitable adjacent area carrier frequency point (earfcn) and Physical Cell Identifier (physical Cell Id) and corresponding reference signal connect
Receive power (RSRP) and Reference Signal Received Quality (RSRQ).
(4) measurement report that base station is reported according to UE judges the adjacent area assigned, (RRC is put by RRC connection reconfigurations
Connection Configuration Reconfiguration) message complete switching command issue.
(5) after UE completes handover operation, RRC connection reconfigurations is reported to put and complete message (RRC Connection
Configuration Reconfiguration Complete)。
