Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1 is a kind of flow diagram for business transmitting method that one embodiment of the invention provides, as shown in Figure 1, described
Method includes the following steps:
S1: when base station receives the scheduling request SR of terminal transmission, Xiang Suoshu terminal sends the starting for being used for allocated subbands
Authorization messages.
Specifically, when terminal needs to send ascending resource, terminal passes through physical uplink control channel (Physical
Uplink Control CHannel, abbreviation PUCCH) scheduling request (Scheduling Request, abbreviation SR).
And in the present embodiment, when base station receives the SR of terminal transmission, then sending starting authorization to the terminal is the end
End distribution meets the subband of pre-set business demand.Such as meet the subband of information exchange business demand, or meet video monitoring
The subband of business demand.
S2: base station receives the buffer status reporting BSR that terminal is sent, and according to the corresponding BSR report value of the BSR, sentences
It is disconnected whether to need to carry out service switching.
In practical applications, terminal by SR to base station requests ascending resource when, only specify whether it has upstream data
It needs to send, oneself needs that how many upstream data sent without indicating.Therefore, terminal needs further to pass through buffer status reporting
It accuses (Buffer Status Report, abbreviation BSR) and tells base station, thereon how many practical upstream data in row buffering buffer
It needs to send, so that base station determines the terminal distribution how many ascending resource given.
Specifically, when terminal receives starting authorization, BSR is sent using ascending resource, and when base station receives terminal
When the BSR of transmission, according to the arrival rate of the current business of BSR report value reflection, BSR report value is compared with preset threshold
Compared with judging whether current business is identical as pre-set business, if they are the same then without carrying out service switching, need to carry out if different
Service switching.
S3: if desired carrying out service switching, and base station executes subband switching scheduling.
Specifically, service switching is if desired carried out, triggering sub-band number changes, and discharges current business resource and starts and awards
Power distribution meets the sub-band resources of new business demand.
It can be seen that the buffer status reporting BSR that the present embodiment is sent by receiving terminal, and it is corresponding according to the BSR
BSR report value, judge whether to need to carry out service switching；If desired service switching is carried out, base station executes subband switching scheduling.
In this way, the business that base station is different according to the practical business arrival rate identification terminal that the BSR that terminal reports reflects, dynamic adjust industry
Business transmit needed for bandwidth, thus avoid always occupied bandwidth resource carry out transmission cause frequency spectrum resource utilization rate not high, Yi Jike
The not high problem of such terminal quantity supported simultaneously.Enable to base station being capable of adaptive same class when carrying out traffic scheduling
The different business feature of Video Monitoring Terminal, so that resource allocation decisions more match business demand.
In an alternate embodiment of the present invention where, in information exchange business transmission process, information exchange business is cut
It is changed to video monitoring service.In the present embodiment, above-mentioned steps S1, specifically can include:
When base station receives the SR of terminal transmission, current business is set as information exchange business, and is used for terminal transmission
For the starting authorization messages of information exchange traffic assignments subband.
Specifically, when base station receives the SR of Video Monitoring Terminal transmission, identification current business is information exchange business,
And starting authorization is sent to distribute the sub-band resources for meeting information exchange business demand.
Further, i.e., in information exchange business transmission process, above-mentioned steps S2 specifically may include following sub-step:
A01, base station receive the BSR that terminal is sent, and judge whether the corresponding BSR report value of the BSR is more than or equal to the
One preset threshold.
If A02, the BSR report value are more than or equal to the first preset threshold, determine the current business for video monitoring
Business, and carry out subband switching.
Specifically, when BSR report value instantaneous value is more than or equal to the first preset threshold, then determine current business for video prison
Control business then needs above-mentioned steps S1 information exchange service switching initially set to be video monitoring service, needs to carry out subband
Switching obtains sub-band number with specific reference to video monitoring service signing Rate mapping.
If A03, the BSR report value less than the second preset threshold, determine the current business for information exchange business,
Keep current business transmission.
Specifically, when BSR report value instantaneous value is less than the second preset threshold, then determine current business for information exchange industry
Business, then it is consistent with above-mentioned steps S1 information exchange business initially set, without carrying out service switching, then current transmission is kept,
Switch without subband.
If A04, the BSR report value are more than or equal to the second preset threshold less than the first preset threshold, multiple BSR is obtained
Report value is located at the probability in the section or the difference of current BSR report value and a upper BSR report value, if the probability is greater than
Predetermined probabilities value or the difference are more than or equal to preset difference value, then determine that the fixed current business is video monitoring industry
Business, and carry out subband switching.
Specifically, when BSR report value instantaneous value is more than or equal to the second preset threshold and less than the first preset threshold, into one
Step judges that BSR report value instantaneous value is located at the number in the section, such as is located at the section when continuous n times occur N-1 times, or current
The difference of BSR report value instantaneous value and the last time BSR report value instantaneous value is positive and is more than or equal to M BSR grade, it is believed that is
Video monitoring service needs to carry out subband switching, obtains sub-band number according to video monitoring service signing Rate mapping.Wherein, N, M
Configurable, value range is [2,255].
In the present embodiment, the configuration of handoff threshold (the first preset threshold and the second preset threshold) mainly considers empty port load-supporting
Ability and the general rate requirement of video monitoring service:
For example, the first preset threshold takes 11 frequency points and video monitoring service to can be used most high-order MCS in statistical time
The corresponding BSR grade of air interface transmission upstream bits number (not including MAC/RLC header overhead).
Second preset threshold takes 4 frequency points and video monitoring service to can be used most high-order MCS in statistical time in air interface transmission
The corresponding BSR grade of row bit number (not including MAC/RLC header overhead).
Wherein, the statistical time is configurable, and value range is [1,255], and unit s, default value is 1s.The value and
The BSR measurement period that RRC reallocation message is allocated to terminal is identical.Configuration foundation is actual test business statistics rate and business label
About rate (Mean Speed), which is compared, is more steadily arranged.
It can be seen that the service switching thresholding being arranged in the present embodiment, it is contemplated that business statistics rate jitter conditions use
Double threshold, be suitable for more video traffic rate scenes, high-speed support be switched fast, low rate carry out repeatedly judge to avoid
Erroneous judgement.
In an alternate embodiment of the present invention where, in video monitoring service transmission process, video monitoring service is cut
It is changed to information exchange business.In the present embodiment, above-mentioned steps S1, specifically can include:
When base station receives the SR of terminal transmission, current business is set as video monitoring service, and is used for terminal transmission
For the starting authorization messages of video monitoring service allocated subbands.
Specifically, when base station receives the SR of Video Monitoring Terminal transmission, identification current business is video monitoring service,
And starting authorization is sent to distribute the sub-band resources for meeting video monitoring service demand.
Further, i.e., in video monitoring service transmission process, above-mentioned steps S2 specifically may include following sub-step:
B01, base station receive the BSR that terminal is sent, and judge whether the corresponding BSR report value of the BSR is more than or equal to the
Two preset thresholds.
If B02, the BSR report value are more than or equal to the second preset threshold, determine the current business for video monitoring
Business keeps current business transmission.
Specifically, when BSR report value instantaneous value is more than or equal to the second preset threshold, then determine current business for video prison
Control business, then it is consistent with above-mentioned steps S1 video monitoring service initially set, without carrying out service switching, then keep working as forward pass
It is defeated, switch without subband.And the read-around ratio that BSR report value average value is less than BSR thresholding is reset.
If B03, BSR report value average value determine less than the second preset threshold and when read-around ratio reaches preset times
The current business is information exchange business, and carries out subband switching.
Specifically, when BSR report value average value is less than the second preset threshold and read-around ratio reaches K times, it is believed that be letter
Interactive service is ceased, then needs for above-mentioned steps S1 video monitoring service initially set to be switched to information exchange business, carries out subband
Switching.Wherein, the configuration of service switching thresholding mainly considers that empty port load-supporting ability and the general rate of video monitoring service are wanted
It asks, the second preset threshold is same as the previously described embodiments, and details are not described herein.K value is configurable, and value range is [1,255].
It can be seen that the service switching thresholding being arranged in the present embodiment, it is contemplated that business statistics rate jitter conditions work as system
Meter speed average value is repeatedly lower than thresholding, just carries out service switching (video monitoring service is switched to information exchange business), keeps away
Exempt from Statistical Rate shake bring erroneous judgement.
It should be noted that in video monitoring service transmission process, BSR that real-time monitoring terminal reports simultaneously is carried out flat
It, is enough to need current business being switched to message exchange service according to step B01~B03 judgement.And in information exchange business
In transmission process, the BSR that real-time detection terminal reports is enough to need for current business to be switched to according to step A01~A04 judgement
Video monitoring service.
In an alternate embodiment of the present invention where, the BSR report value average value in above-described embodiment in step B03, can
It obtains by the following method:
Base station is filtered the BSR report value received and smoothly acquires BSR report value average value, is become with reflection caching variation
Gesture.
In the present embodiment, read-around ratio described in above-mentioned steps B03 is BSR report value average value less than the second default threshold
The read-around ratio of value can obtain in the following way:
Base station judges the size relation of BSR report value average value Yu BSR thresholding, and statistics BSR report value average value is less than BSR
The read-around ratio of thresholding.
Further, based on the above embodiment, the method also includes following steps:
When the BSR report value that the base station receives is zero, judge whether is BSR report value that continuous radio frames receive
It is zero；If the BSR report value that continuous radio frames receive is zero, determine that the BSR for ending BSR, and stops pair
BSR report value average value less than the read-around ratio of the second preset threshold statistics, until receive non-ending BSR BSR report
Announcement value.
Specifically, when receiving BSR report value is zero, terminal side caching may be indicated for sky, it is also possible to indicate terminal
Side high-level business rate is zero, different according to the triggered time of the two, and terminal side caching reports each wireless for the BSR of empty triggering
Frame all occurs, and the BSR report cycle that terminal side high-level business rate is zero triggering occurs.Therefore work as and receive BSR report value
It is zero, further judges that receiving BSR report value zero if it is continuous radio frames is then judged as ending BSR, ending BSR
It is not involved in filtering and stops the read-around ratio statistics for being less than BSR thresholding 2 to BSR report value average value, it is non-until receiving
The BSR report value of ending BSR restarts filtering and statistical counting；Remaining situation is all filtered smooth and statistics meter
Number.
Specifically, above-mentioned steps S3 is specifically included:
The base station sends the closing authorization messages transmitted for terminating current business to the terminal, and to the terminal
Send the starting authorization messages for redistributing subband.
For example, if being video monitoring service by information exchange service switching, triggering sub-band number changes, and discharges current industry
It business resource and sends starting authorized appropriation and meets the sub-band resources of video monitoring service demand；If video monitoring service is switched
It for information exchange business, triggers sub-band number and changes, discharge current business resource and send starting authorized appropriation and meet information friendship
The sub-band resources of mutual business demand.
In order to illustrate more clearly of the solution of the present invention, illustrate a kind of industry below by a more specific embodiment
Business transmission method.As shown in Fig. 2, the business transmitting method in the present embodiment specifically comprises the following steps:
S201: when base station receives the SR that terminal reports, Xiang Suoshu terminal sends starting authorization messages with allocated subbands.
Wherein, when base station receives the SR that terminal reports, it is that the terminal distribution meets that Xiang Suoshu terminal, which sends starting authorization,
The subband of pre-set business demand.The pre-set business can be information exchange business or video monitoring service.
S202: after terminal receives the starting authorization messages, according to BSR trigger mechanism and report mechanism to the base station
Send BSR.
S203: base station judges whether to need to carry out service switching according to BSR report value, if so, step S204 is gone to, it is no
Then go to step S205.
Wherein, base station determines that Video Monitoring Terminal executes video according to BSR and its with the matching relationship of air interface transmission ability
Monitoring business or information exchange business, and carry out scheduling decision.Specifically, real in information exchange business transmission process
When the monitoring BSR that reports of terminal, whether identification business switch to video monitoring service；In video monitoring service transmission process,
