The method of the present embodiment comprises step S1 and step S2.
In step S1, base station judges whether the transmission feature information of a subscriber equipment meets the first predetermined condition.
Wherein, described transmission feature information comprises the information of the data transmission characteristics that can reflect subscriber equipment.Particularly, the transmission feature information of this subscriber equipment comprises:
1) the average transmission rate information of this subscriber equipment.
For example, the average transmission rate of subscriber equipment is 2.58Kbit/s etc.
2) data amount information current to be sent of this subscriber equipment.
For example, in base station, the current data volume that need to send to subscriber equipment is 68Kbits etc.
Preferably, transmission feature information also can comprise following at least one:
1) carrying of subscriber equipment (bear) type information;
For example, the bearer types of subscriber equipment comprises Non-GBR (non-GBR) and GBR type etc.
2) channel quality information of subscriber equipment.
For example, channel SINR (Signal to Interference plus Noise Ratio), the SNR (signal to noise ratio) etc. of subscriber equipment.
It should be noted that, above-mentioned transmission feature information is only for giving an example, and other transmission feature information, as applicable to the present invention, also should be included in protection range of the present invention, and are contained in this with way of reference.
Wherein, described the first predetermined condition comprises that any can be used in judges the whether condition of applicable data packing pattern of subscriber equipment.Particularly, based on the first predetermined condition, the average transmission rate information of subscriber equipment is less, it is judged as, and to be applicable to the possibility of data packings pattern higher, and the data amount information current to be sent of subscriber equipment is less, it is judged as, and to be applicable to the possibility of data packings pattern higher.
Preferably, the first predetermined condition includes but not limited to:
1) the average transmission rate information of subscriber equipment is less than the first set rate threshold value.
For example, the average transmission rate information of subscriber equipment is less than 5Kbit/s etc.
2) data amount information current to be sent of subscriber equipment is less than the first predetermined amount of data threshold value.
For example, the data amount information current to be sent of subscriber equipment is less than 20Kbits etc.
More preferably, in the time that transmission feature information also comprises the average transmission rate information of subscriber equipment and/or current data volume to be sent, the first predetermined condition also comprises following at least one:
1) subscriber equipment only has the bearer types of non-GBR;
For example, the first predetermined condition comprises that subscriber equipment only comprises the carrying of Non-GBR type, does not comprise the carrying of GBR type etc.
2) channel quality information of subscriber equipment is better than the first predetermined quality threshold value.
For example, the SINR of subscriber equipment is greater than 2dB etc.
It should be noted that, above-mentioned the first predetermined condition is only for giving an example, and other predetermined conditions, as applicable to the present invention, also should be included in protection range of the present invention, and are contained in this with way of reference.
In step S2, in the time of transmission feature information conforms the first predetermined condition, base station arranges subscriber equipment and enters data packing pattern, with according to based on the scheduled time in definite time interval of rule, sends schedule information to subscriber equipment.
Particularly, data packing modal representation base station, by according to based on the scheduled time in definite time interval of rule, sends schedule information to subscriber equipment.Particularly, base station basis is based on the scheduled time in definite time interval of rule, and the mode that sends schedule information to subscriber equipment includes but not limited to:
1) in scheduled time rule, directly stipulate definite time interval, in definite time interval that base station directly stipulates according to scheduled time rule, sent schedule information to subscriber equipment; Wherein, this definite time interval can be a fixed value, also can be multiple different values.
For example, scheduled time rule has directly stipulated a definite time interval 100ms, each execution to subscriber equipment sends after the operation of schedule information, interval 100ms, base station is just carried out the operation that sends schedule information to subscriber equipment again, so circulation, until this subscriber equipment departs from data packing pattern.
Again for example, scheduled time rule has directly stipulated multiple different value 100ms, 90ms and 110ms, and base station is carried out first to subscriber equipment and sent after the operation of schedule information, and interval 100ms just carries out the operation that sends schedule information to subscriber equipment again; Then,, after the 90ms of interval, base station is carried out the operation that sends schedule information to subscriber equipment again; Then,, after the 110ms of interval, base station is carried out the operation that sends schedule information to subscriber equipment again; Then,, after the 100ms of interval, base station is carried out the operation that sends schedule information to subscriber equipment again; So circulation, until this subscriber equipment departs from data packing pattern.
2) scheduled time rule comprises the rule of determining the time interval according to current data volume to be sent, base station is each carries out while sending the operation of schedule information to subscriber equipment or after operation, all regular to schedule, determine the time interval of this user not being dispatched based on current data volume to be sent, and after the determined time interval, just again carry out the operation that sends schedule information to subscriber equipment.
For example, scheduled time rule comprises the following mapping relations table (seeing the following form 1) in current data volume to be sent and the time interval:
| Current data volume to be sent | The time interval |
| 0-5Kbits | 300ms |
| 5-15Kbits | 150ms |
| 15-25Kbits | 100ms |
| 25-70Kbits | 50ms |
| Be greater than 70Kbits | 20ms |
Table 1
Base station is carried out first to subscriber equipment and is sent after the operation of schedule information, current data volume to be sent is 2Kbits, the upper table 1 of base station inquiry definite time interval are 300ms, and, after the 300ms of interval, base station is just carried out the operation that sends schedule information to subscriber equipment again; Then, base station is 17Kbits according to current data volume to be sent, determines that the time interval is 100ms, and, after the 100ms of interval, base station is just carried out the operation that sends schedule information to subscriber equipment again; So circulation, until this subscriber equipment departs from data packing pattern.
Again for example, scheduled time rule predetermining: the current data volume to be sent in the time interval=1000/; Base station is carried out first to subscriber equipment and is sent after the operation of schedule information, current data volume to be sent is 10Kbits, base station interval=1000/10=100ms computing time,, after the 100ms of interval, base station is just carried out the operation that sends schedule information to subscriber equipment again; Then, base station is 17Kbits according to current data volume to be sent, determines the time interval=1000/17=59ms, and, after the 59ms of interval, base station is just carried out the operation that sends schedule information to subscriber equipment again; So circulation, until this subscriber equipment departs from data packing pattern.
Preferably, in the time interval definite based on scheduled time rule, do not carry out the operation that sends schedule information to subscriber equipment for making base station, base station can remove subscriber equipment from treat scheduler object, for example, in pre-scheduling (pre-scheduling) stage, subscriber equipment is removed from treat scheduler object.Then, when after the time interval definite based on scheduled time rule, then subscriber equipment is added and treated in scheduler object, dispatch together with other subscriber equipmenies, send until successfully this subscriber equipment is completed to a schedule information; Or, in order to ensure the schedule information that can successfully send this subscriber equipment, can, after the time interval definite based on scheduled time rule, force this subscriber equipment to carry out the transmission of a schedule information.
It should be noted that, above-mentioned for example only for technical scheme of the present invention is described better, but not limitation of the present invention, those skilled in the art should understand that, any in the time of transmission feature information conforms the first predetermined condition, subscriber equipment is set and enters data packings pattern, with according to based on the scheduled time in definite time interval of rule, send the implementation of schedule information to subscriber equipment, all should be within the scope of the present invention.
The present invention notices such phenomenon: the application of upgrading with detection for many continuous request mobile networks, as MSN, Twitter, QQ etc., major part in the data session of its initiation is often very short and only comprise a small amount of valid data information, for example, may be less than 10 seconds and be less than up to 60% session request up to 80% session persistence the data of 1Kbit, in this case, uplink/downlink control channel in session can occupy a large amount of interface-free resources, and only leaves a small amount of resource for secured transmission of payload data.In the present invention, whether meet the first predetermined condition by the average transmission rate information and the current data amount information to be sent that judge subscriber equipment, whether can judge subscriber equipment is the subscriber equipment that sends or receive small data quantity with upper frequency, and when judging that subscriber equipment is when sending or receive the subscriber equipment of small data quantity with upper frequency, based on scheduled time rule, determine and in a relative prior art, send the time interval that the frequency of schedule information is grown, and in the time interval, do not send schedule information to subscriber equipment, and only after this time interval, concentrate to subscriber equipment and send the schedule information of accumulating, thus, base station can be by the disposable transmission of schedule information that originally need to repeatedly send respectively, thereby can greatly reduce the shared resource of uplink/downlink control channel, for example, carry out after the solution of the present invention, in the time there is 600 users in a honeycomb, can save the cellular signal load of about 30%-50%.Preferably, because GBR load bearing requirements regularly sends schedule information, and, if in the case of the channel quality of subscriber equipment is poor, may cause subscriber equipment to be difficult to receive the schedule information that the disposable transmission in base station is accumulated, therefore, in the present invention, also with reference to bearer types and the channel quality of subscriber equipment, only to comprise that at bearer types Non-GBR carrying and channel quality preferably in situation, arrange subscriber equipment and enter data packing pattern.
As one of preferred version of the present embodiment, method of the present invention also comprises the steps S3.
In step S3, in the time of transmission feature information conforms the first predetermined condition, base station arranges subscriber equipment and enters non-frequency selection scheduling (frequency diverse scheduling) pattern.
Subscriber equipment is set to after non-frequency selection scheduling pattern, and subscriber equipment can be compared the more detailed channel quality information (as A-CQI) of primary channel quality information (as P-CQI) without reporting.
Owing to entering after data packing pattern, the shared channel resource of channel quality information of user equipment to report can, without obtaining more detailed channel quality information, thus, can further be reduced in base station.
As one of preferred version of the present embodiment, method of the present invention also comprises the steps S4.
In step S4, in the time meeting the second predetermined condition, base station arranges described subscriber equipment and departs from described data packing pattern.
Wherein, described the second predetermined condition comprises that any can be used in judges whether subscriber equipment should depart from the condition of data packing pattern.Preferably, the second predetermined condition comprises following at least one:
1) the average transmission rate information of subscriber equipment is greater than the second set rate threshold value, and wherein, the second set rate threshold value is more than or equal to the first set rate threshold value.
For example, the average transmission rate information of subscriber equipment is greater than 10Kbit/s.
Due to when average transmission rate information is higher than after to a certain degree, can think that subscriber equipment needs relatively large ground downloading data, therefore in the case, should depart from the data pattern of packing, to prevent from reducing the data speed of download of subscriber equipment.
2) data amount information current to be sent of subscriber equipment is greater than the second predetermined amount of data threshold value, and wherein, the second predetermined amount of data threshold value is more than or equal to the first predetermined amount of data threshold value.
For example, the data amount information current to be sent of subscriber equipment is greater than 100Kbits.
After being greater than to a certain degree when current data amount information to be sent, can think that data packing pattern has caused data to overstock, therefore in the case, should depart from data packing pattern, to prevent from overstocking too much data.
3) channel quality information of subscriber equipment is lower than the second predetermined quality threshold value, and wherein, the second predetermined quality threshold value is less than or equal to the first predetermined quality threshold value.
For example, the channel quality information of subscriber equipment is lower than 1.5dB.
If because current channel quality information is excessively poor, data packing pattern may cause subscriber equipment cannot receive the packing data of the disposable transmission in base station, therefore in the case, should depart from data packing pattern.
4) subscriber equipment is set up the carrying of GBR type.
For example, base station receives that subscriber equipment is for asking the request of the carrying of setting up GBR type, or base station spontaneous be the carrying etc. of user equipment allocation GBR type.
Because the carrying of GBR type has often stipulated to send datagram with the shorter time interval, as the time interval to be less than 10ms sends packet, this shorter time interval is longer than definite time interval under data packing pattern conventionally, therefore in the case, should depart from data packing pattern.Depart from after data packing pattern, the primitive scheduling configuration of subscriber equipment can be recovered in base station.
The present embodiment can be worked as and detected when subscriber equipment is no longer applicable to data packings pattern, departs from data packing pattern.
As one of preferred version of the present embodiment, method of the present invention also comprises the steps S5 and S6.
In step S5, in the time that subscriber equipment enters data packing pattern, the time interval reprovision that sends the control signal relevant to its scheduling to subscriber equipment is set to the first predetermined time interval by base station.
For example, in the time that subscriber equipment enters data packing pattern, the time interval reprovision that sends the control signal relevant to its scheduling to subscriber equipment is set to 80ms by base station.
In step S6, in the time that subscriber equipment departs from described data packing pattern, the time interval reprovision that sends the control signal relevant to its scheduling to subscriber equipment is set to the second predetermined time interval by base station.
Wherein, the first predetermined time interval is longer than the second predetermined time interval.
Preferably, the control signal relevant to the scheduling of subscriber equipment includes but not limited to: P-CQI, SR, SRS etc.
Due under data packing pattern, the time interval that sends schedule information is elongated, therefore, can correspondingly extend the transmission time interval of the control signal relevant to scheduling, thereby further reduce the shared mobile network resource of these control signals.And in the time that subscriber equipment departs from data packing pattern, the time interval that sends schedule information can be reverted to original time interval (i.e. the second predetermined time interval).
It should be noted that, as a kind of preferred version, base station can be in the situation that connected subscriber equipment exceedes a predetermined quantity, as exceedes in the situation of 200, carries out above-mentioned steps S1 and S2 and preferred steps S3 to S6.
