Duration: application layer estimates that the time that this service rate will continue, unit can be seconds, minute, hour.Or the classification of a duration, such as a long time, the middle time, the short time, time length can by arranging thresholding to control.

Traffic carrying capacity: application layer estimates the data volume size of business, and unit can be KB (kilobytes), MB (Mbytes), GB (gigabyte).

Wherein, application layer business information is transmitted by the interlayer interface arranged between application layer and Access Layer.

Such as utilize SRB1/2 (Signaling Radio Bearer 1/2) or introduce a new radio bearer (Radio Bearer, RB) and carry or utilize MAC CE to transmit.

1502, the Access Layer of terminal is the application layer business information of terminal, submits to the Access Layer of base station.

Specifically by means of the peer layer communication between terminal and base station.Such as RRC connects, MAC CE.Or specifically can introduce a new measurement type, " application layer traffic measurement ", under base station, signaling comes the measurement configuration of control terminal, Report mode, measurement triggering condition.Such as base station can configurating terminal, and execution cycle property reports, and reports interval 30 seconds.

Or base station can configurating terminal, execution event triggers and reports, once application layer puberty changes, reports immediately.Can be specifically RRC measurement report or MAC layer measurement report.

1503, base station gets the application layer business information of terminal, carries out RRM (RRM) and optimizes.

Based on getting application layer business information, carry out optimizing scheduling.Below can being specifically one of at least:

The ratio of uplink subframe to downlink subframe carrying out TDD system distributes.

Because base station can to get in following a period of time up-downgoing service rate along with the distribution curve of time, base station utilizes this information, select a time point, carry out up-downgoing proportioning, ensure to mate between ratio of uplink subframe to downlink subframe and up-downgoing service rate demand, thus maximum capacity.Specifically:

When downlink business increase in demand, by reshuffling ratio of uplink subframe to downlink subframe, increase the available descending sub frame of system; Or

When uplink service increase in demand, by reshuffling ratio of uplink subframe to downlink subframe, increase the available upstream subframe of system;

Carry out load balance control:

In prior art, the load of base station is heavier and after reaching certain thresholding, just starting load balanced algorithm, if neighboring cell loading comparatively gently then some terminal switch to the lighter community of adjacent load, thus can reach the object of load balance.In the present embodiment,

Because base station can to get in following a period of time service rate along with the distribution curve of time, if base station judges that next oneself can not meet these business demands completely, and neighbor cell relative free, so base station can foresee in advance and can carry out load balance control, thus Pre-handoff part terminal is to neighbor cell, vacant resource out can meet business demand in terminal to greatest extent, serves these switch the maximum capacity of business in the past by allowing neighbor cell.

Access control:

In prior art, resource in base station has and takies resource (resource that the terminal of having served has used), reserved resource (keep for the terminal of having served, do not use temporarily), idling-resource (keep for new access terminal).

Access control is carried out according to the current load (specifically taking resource, reserved resource, idling-resource etc.) of self, the business etc. of new terminal current request in base station, does not consider the impact that follow-up business load situation controls current admission.Such as one may after having received new terminal, cross a period of time T1, because originally the business demand of service terminal there occurs change, such as increase in demand, and now, base station, because cause not having extra resource to be supplied to the further business demand of original service terminal after having received new terminal, causes business business experience to decline.For another example, a kind of possibility base station is when carrying out the call access control receiving new terminal, because need more reserved resource to the terminal of originally having served, and the access causing not having enough resources and refuse this terminal, but after having crossed a period of time T2, originally the business demand of service terminal there occurs change, such as slump in demand, so, in fact base station can first receive new terminal to provide service, and after original terminal traffic slump in demand, the new terminal that is supplied to that completely can be abundant enters business demand.The reserved resource of prior art cannot accurately be reserved, and there is error.

And in the present embodiment, because base station can to get in following a period of time service rate along with the distribution curve of time, when there being new terminal to initiate access, base station, according to the grade of the terminal of having served and business information, the Radio Resource situation of free time, the business demand of new terminal, judges whether the access of receiving new terminal.

If such as current radio resource can meet the business demand of application layer business information display, and follow-up also have the release of more how vacant resource, and current all vacant resources and reserved resource meet the demand of the access service of new terminal, then receive the access of new terminal; If or current all vacant resources and reserved resource can meet the business demand of application layer business information display, but after a time T, the terminal traffic demand of original service will rise, in that moment, because reserved resource will be taken by original terminal, cause all vacant resources and reserved resource cannot meet the demand of the business of this new terminal, then refuse the access of new terminal.Or reduce the service rate that current service terminal is current and follow-up, receive the access of new terminal.

According to preceding step, base station can get the business information in following a period of time.The distribution curve along with the time of such as service rate.

If multiple terminal, then the information of multiple terminal can be superposed, obtain comprehensive business statistics information.

If application layer business information comprises " duration " in 1501 steps, then base station can think that in the ensuing time be " duration ", if do not comprise " duration " in 1501 steps in application layer business information, then base station can be defaulted as " ensuing time " is receiving the time before next application layer business information.
