A kind of resource allocation methods, this method may further comprise the steps:
A, when the user of resource to be allocated is in the edge of sub-district; For each frequency that said sub-district disposed; Confirm to meet in the neighbor cell quantity of user on each ascending time slot of neighbor; Said neighbor is the user of this frequency of configuration and contiguous said resource to be allocated, selects the candidate time slot of the minimum ascending time slot of said quantity as this frequency, and with the selection coefficient of said quantity as this frequency;
B, according to the ascending order of said selection coefficient, for the user of said resource to be allocated distributes frequency, and candidate's time slot configuration that the frequency that is distributed is corresponding is given the user of said resource to be allocated.
In sum; The resource allocation methods that the present invention proposes is to the user at the edge that is in the sub-district, the resource of the edge customer minimum number of configuration co-frequency co-time slot in the adjacent sub-district of priority allocation; Same frequency to reduce neighboring interval disturbs; Thereby can effectively reduce the possibility that power competes to lift, reduce the fluctuation of ISCP, and then can reduce because ISCP can't accurately predict the irrational possibility of the resource allocation that causes; (key performance index is KPI) with user's impression for the Key Performance Indicator of elevator system.
Description of drawings
Fig. 1 is the schematic flow sheet of the embodiment of the invention one.
Embodiment
For making the object of the invention, technical scheme and advantage clearer, the present invention is done to describe in detail further below in conjunction with accompanying drawing and specific embodiment.
Core concept of the present invention is: through according to reduce the adjacent area with the strategy that frequently disturbs as far as possible; Be suitable carrier frequency and the time interval resource of edge customer configuration; Thereby can reduce because the conversation loss due to disturbing, and then reduce the ISCP lifting, the KPI of system experienced with the user all get a promotion.
Fig. 1 is the schematic flow sheet of the embodiment of the invention one.As shown in Figure 1, this embodiment mainly comprises:
Step 101, when the user of resource to be allocated is in the edge of sub-district; For each frequency that said sub-district disposed; Confirm to meet in the neighbor cell quantity of user on each ascending time slot of neighbor; Said neighbor is the user of this frequency of configuration and contiguous said resource to be allocated, selects the candidate time slot of the minimum ascending time slot of said quantity as this frequency, and with the selection coefficient of said quantity as this frequency.
Here; When the user of resource to be allocated is in the edge of sub-district, before being this user resource allocation, need earlier each frequency resource to the sub-district disposed; Confirm it and select coefficient; This selection coefficient is the number of users through the user who adds up on each ascending time slot this frequency of configuration in the neighbor cell and contiguous said resource to be allocated, and then in subsequent step according to the selection coefficient magnitude of each frequency, be the user resource allocation of said resource to be allocated.So, can be preferably the user and be assigned to the resource that produces the interference of less adjacent area, thereby can reduce the fluctuation of ISCP.
Preferably, the concrete grammar that the user who confirms said resource to be allocated is in the edge of sub-district can adopt following method to realize:
Judge whether to satisfy RSCP 11-RSCP 12＜L 1, if, confirm that then said resource to be allocated is in the edge customer of sub-district, wherein, RSCP 11For the user of said resource to be allocated receives the received signal code power of the PCCPCH of its sub-district, place, RSCP 12Receive the received signal code power of the PCCPCH of the neighbor cell that is close to its present position for the user of said resource to be allocated.
Said L 1Be preset threshold value, L 1>=0, this value is provided with can make that the scope of cell edge is bigger when big, need consider that when Resources allocation the adjacent area is many with the user who disturbs frequently; Can make that like this overhead is excessive; And when this value be provided with hour, can make that the scope of cell edge is less, need consider that when Resources allocation the adjacent area is fewer with the user who disturbs frequently; Like this, utilize the present invention to reduce the DeGrain of the fluctuation of ISCP.Those skilled in the art can be L through emulation according to actual needs 1Select suitable value.
