Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, referring to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
The embodiment of the invention provides a kind of method of adjusting time slot configuration, its flow process as shown in Figure 1, comprising:
Step 201: for selecting initial time slot configuration mode in each residential quarter;
Step 202: after network enters normal operation, the resource operating position that this residential quarter of each cell measurement is current;
Step 203: whether judge this residential quarter in up direction or the limited and concrete limited direction of down direction according to the current resource operating position in described each residential quarter, restricted cell is defined as needing to adjust the Target cell of time slot configuration;
Step 204: select the larger time slot configuration mode of subframe proportion of limited direction for each Target cell, as the target time slot configuration mode of each Target cell;
Step 205: the time slot configuration of adjusting each Target cell according to the time slot configuration mode of the target time slot configuration mode of each Target cell and its adjacent area.
Wherein, when selecting initial time slot configuration mode for each residential quarter in the step 201, can arrange according to up-downgoing traffic carrying capacity ratio the most general under this network applied environment of living in, such as generally, can be numbered 1 configuration mode in the option table 1---namely, the sub-frame number that is used for up-downgoing is equal, and its ratio is 4/4.Simultaneously, easily understand, described step 201 needs are used for network and move first, in case after network enters normal operation, if its time slot configuration mode need to be adjusted in the residential quarter, only need execution in step 202～step 205 to get final product.
And in the step 202, after network enters normal operation, the current resource operating position in this residential quarter need to be measured in each residential quarter, if when the time slot configuration mode of finding this current use in residential quarter and actual up-downgoing traffic carrying capacity ratio can not fine couplings, just need to adjust the time slot configuration mode of this residential quarter.Described current resource operating position, the service quality (Quality of Service, QoS) of information on load, uplink service and downlink business that can be by measuring uplink and downlink, and system performance index.Wherein, the information on load of described uplink and downlink can comprise one or more in resources occupation rate, interference and the transmitting power; The QoS of uplink service and downlink business can comprise one or more in the parameters such as throughput, Block Error Rate, time delay and packet loss; System performance index can comprise one or more in the parameters such as admittance success rate, cutting off rate, small area jam time and congestion probability of up-downgoing.Hereinafter for convenience of description, above-mentioned various parameters are referred to as the resource performance parameter.
Correspondingly, judge that according to the current resource operating position in described each residential quarter this residential quarter whether in the method for the limited and concrete limited direction of up direction or down direction, illustrates as follows in the step 203:
Resources occupation rate in the information on load of uplink and downlink is as example, the resources occupation rate of statistical system in the setting-up time section, supposing the system surpasses predefined the first thresholding in the resources occupation rate of first direction, and another direction (namely with first party in the opposite direction, if first direction is up direction, then this another direction is down direction) resources occupation rate be lower than predefined the second thresholding, and the duration reaches predefined time threshold, can judge that then this residential quarter is limited, and its limited direction is first direction, and this residential quarter is defined as Target cell.
Described method can be applied on other parameter equally, such as the packet loss of statistical system in the setting-up time section, if system surpasses predefined the first thresholding at the packet loss of first direction, and be lower than predefined the second thresholding at the packet loss of another direction, and the duration reaches predefined time threshold, can judge that then this residential quarter is limited, and its limited direction is first direction, this residential quarter is defined as Target cell.
Easily understand, can also use simultaneously the method to a plurality of parameters equally, at this moment, can independently carry out described judgement to each parameter, as long as exist at least one parameter to satisfy described thresholding Rule of judgment, just this residential quarter is defined as Target cell;
Also can merge judgement to a plurality of parameters, at this moment, for any one residential quarter, set respectively corresponding first, second thresholding and time thresholding for each resource performance parameter of this residential quarter in advance; Comprise in the current resource operating position that for example certain cell measurement obtains: the admittance success rate of resources occupation rate, throughput, Block Error Rate, up-downgoing and cutting off rate be totally 5 parameters, and each parameter is corresponding first, second thresholding of cover and a time thresholding respectively; Suppose, in the setting-up time section, the resources occupation rate of this residential quarter, Block Error Rate and 3 parameters of the cutting off rate respectively value on first direction have surpassed the first thresholding of its correspondence, and the value on other direction is lower than the second thresholding of its correspondence, and the duration surpasses its corresponding time threshold; Simultaneously, system presets when the parameter that surpasses 50% and satisfies its corresponding thresholding Rule of judgment and the limited direction judged when identical, and this residential quarter is defined as Target cell.Then easily understand, this moment is in 5 resource performance parameters, have 3 parameters to satisfy its corresponding thresholding Rule of judgment, and limited direction is first direction, therefore this residential quarter is defined as needing to adjust the Target cell of time slot configuration and the limited direction of this residential quarter is first direction.
Certainly, also there is the form of multiple other variation and replacement in the concrete grammar that a plurality of parameters are merged judgement, and those skilled in the art easily expect, enumerates no longer one by one as space is limited herein.
The method of step 204 comprises:
If it is up limited that Target cell is under the current time slots configuration, one or more configuration modes that then the sub-frame of uplink proportion is higher in the option table 1 are as the target time slot configuration mode, otherwise, if be in descending limitedly under the current configuration, one or more configuration modes that then the descending sub frame proportion is higher in the option table 1 are as the target time slot configuration mode; Perhaps, can also add up the ratio of the sub-frame number that ascending resource takies in the setting-up time section sub-frame number and downlink resource take, then from described table 1, select with the immediate time slot configuration mode of this ratio as the target time slot configuration mode.
