Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference 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: be the initial time slot configuration mode of each cell selecting;
Step 202: after network enters normal operation, the resource operating position that this sub-district of each cell measurement is current;
Step 203: whether judge this sub-district in up direction or the limited and concrete limited direction of down direction according to the current resource operating position in described each sub-district, restricted cell is defined as needing to adjust the Target cell of time slot configuration;
Step 204: for each Target cell is selected the bigger time slot configuration mode of subframe proportion of limited direction, 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 in the step 201 being the initial time slot configuration mode of each cell selecting, can be provided with 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---promptly, the sub-frame number that is used for up-downgoing equates that its ratio is 4/4.Simultaneously, understand easily, 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 be adjusted in the sub-district, 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 sub-district need be measured in each sub-district, if the time slot configuration mode of finding this current use in sub-district and actual up-downgoing traffic carrying capacity ratio can not be fine during coupling, just need adjust the time slot configuration mode of this sub-district.Described current resource operating position, the service quality of information on load, uplink service and downlink business that can be by measuring uplink and downlink (Quality of Service, QoS), 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 sub-district this sub-district whether in the method for the limited and concrete limited direction of up direction or down direction, illustrates as follows in the step 203:
With the resources occupation rate in the information on load of uplink and downlink is example, the resources occupation rate of statistical system in the setting-up time section, supposing the system surpasses predefined first thresholding in the resources occupation rate of first direction, and another direction (promptly with first party in the opposite direction, if first direction is a up direction, then this another direction is down direction) resources occupation rate be lower than predefined second thresholding, and the duration reaches predefined time threshold, can judge that then this sub-district is limited, and its limited direction is a first direction, and this sub-district 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 first thresholding at the packet loss of first direction, and be lower than predefined second thresholding at the packet loss of another direction, and the duration reaches predefined time threshold, can judge that then this sub-district is limited, and its limited direction is first direction, this sub-district is defined as Target cell.
Understand easily, can also use this method simultaneously to a plurality of parameters equally, at this moment, can independently carry out described judgement,, just this sub-district is defined as Target cell as long as exist at least one parameter to satisfy described thresholding Rule of judgment to each parameter;
Also can merge judgement, at this moment,, set corresponding first, second thresholding and time thresholding respectively for each resource performance parameter of this sub-district in advance for any one sub-district to a plurality of parameters; For example comprise in the current resource operating position that 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, corresponding respectively first, second thresholding of cover and the time thresholding of each parameter; Suppose, in the setting-up time section, the resources occupation rate of this sub-district, Block Error Rate and 3 parameters of the cutting off rate value on first direction have respectively surpassed first thresholding of its correspondence, and the value on other direction is lower than second thresholding of its correspondence, and the duration surpasses its time corresponding thresholding; Simultaneously, system preestablishes when the parameter that surpasses 50% and satisfies its corresponding thresholding Rule of judgment and the limited direction judged when identical, and this sub-district is defined as Target cell.Then understand easily, 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 sub-district is defined as needing to adjust the Target cell of time slot configuration and the limited direction of this sub-district is a 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 expect easily, 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, then one or more configuration modes that 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, then one or more configuration modes that 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, from described table 1, select then with the immediate time slot configuration mode of this ratio as the target time slot configuration mode.
Different according to the authority of equipment in the network and mode of operation, the LTE-TDD system can be divided into centralized, distributed and hybrid three kinds of frameworks usually, correspondingly, those skilled in the art understand easily, the executive agent of above-mentioned steps 202～205 is according to the framework difference of LTE-TDD system, multiple compound mode can be arranged, will attempt several examples below and be further elaborated:
If a system architecture is centralized, then can further be divided into 3 kinds of situations.
