[0005] In the process of implementing the present invention, the inventor found that: the prior art lacks quantitative indicators to measure the effect of uplink and downlink time slot allocation, and lacks quantitative indicators to measure the impact of cross-slot time slots. Therefore, it is impossible to quantitatively analyze the overall performance of the network under different time slot allocations.

[0150] In addition, you can also use the above Figure 9 Based on the first embodiment of the optimization device for uplink and downlink time slot allocation of the present invention shown:
[0151] A retaining unit, retaining the cluster boundary information determined by the comparison determination unit 94;
[0152] a storage unit, storing a preset threshold for the number of times of cyclic execution of the time slot allocation;
[0153] The loop control unit judges whether the number of execution times of time slot allocation exceeds the threshold value until this time, and if so, compares the cluster boundary information determined by the reserved loops, and uses the smallest slot in the reserved cluster boundary The cluster boundary corresponding to the allocation cost is used for slot allocation.
[0154] It is worth noting that the monotonically increasing function form may also be replaced by a piecewise function or the like.

The invention discloses a method for quantizing the cost of slot assignment between an uplink and a downlink, which includes the processes: obtaining a parameter for indicating a mode unbalance extent generated in the slot assignment between the uplink and the downlink, adopting a monotone increasing function containing an upper limit value and forming a relationship between the parameter which is considered as an independent variable and the slot assignment between the uplink and the downlink as the dependent variable of the function. The invention also discloses a method for quantizing the crossed slot, a method for assigning the slot between the uplink and the downlink and an optimization method for assigning the slot between the uplink and the downlink and a corresponding equipment. By adopting the invention, quantization of cost for slot assignment between the uplink and the downlink is realized, the complete performance of the network under different slot assignment is quantizedand analyzed, slot assignment between the uplink and the downlink is realized by way of quantization, and the network is optimized. Besides, the invention is easy to implement.
Description
technical field [0001] The present invention relates to the communication field, in particular to a method for quantifying uplink and downlink time slot allocation costs, a quantization method for crossover time slot costs, a method for uplink and downlink time slot allocation, a method for optimizing uplink and downlink time slot allocation, and corresponding equipment. Background technique [0002] The third-generation mobile communication standard Time Division Synchronous Code Division Multiple Access (TD-SCDMA) proposed by my country is a Time Division Duplex (TDD) system. In the TD-SCDMA system, different numbers of uplink and downlink time slots can be allocated dynamically according to the business conditions of the cell. This flexible resource allocation method enables the TD-SCDMA system to flexibly respond to different business requirements and changes in requirements. However, at the same time, an efficient Dynamic Channel Allocation (Dynamic Channel Allocation,...
