Compared with prior art, the present invention has the following advantages:
By using the technical scheme that the embodiment of the invention proposed, make transmitting-receiving power, throughput and the number of users load of intercarrier balanced more, the user on the heavier carrier wave of can avoiding loading experiences variation, and, when improving resource utilization, also help the stability of hardware device.
Below, the application scenarios in conjunction with concrete is elaborated to the technical scheme that the embodiment of the invention proposed.
With respect to defective of the prior art, the embodiment of the invention has proposed a kind of when carrier wave sorts, and comprehensive multiple measuring amount is considered the dynamic channel allocation algorithm of carrier load equilibrium.
This algorithm is applicable to the HSPA system, specifically can be divided into two parts:
When first, HSPA service access, select the lower carrier wave of existing load to insert.
During the HSPA service access, factors such as composite carrier signal transmission/received power, accessed user's number, throughput when the SDCA algorithm sorts to the HSPA carrier wave, determine the load that each carrier wave is current, wherein, the low more carrier wave priority of loading is high more, therefore, can select its medium priority the highest, the minimum carrier wave of just loading inserts this user.
Wherein, ask the carrier type that inserts according to the user, corresponding processing procedure further can be divided into following two kinds of situations:
Situation one, user ask to insert the HSDPA carrier wave
At first, carrying out carrier wave based on transmitted power selects.
Investigate the downlink transmission power measuring amount of the HS-PDSCH shared channel of HSDPA carrier wave, in concrete application scenarios, the average transmitting power height of carrier wave shared channel just illustrates shared channel utilance height, and idling-resource is less.Therefore, the carrier wave that average transmitting power is lower illustrates that the shared channel idling-resource is more, is fit to insert new user, and its access priority is high more.
Secondly, carrying out carrier wave based on the access customer number amount selects.
If exist the power of a plurality of carrier waves identical, and be minimum, or each carrier power is full power, promptly do not have idle shared channel resources, then consider the HSPA number of users that inserted, the carrier wave priority that number of users is few more is high more.
Once more, select based on throughput.
Send or be all lowest power for being full power, and the also identical carrier wave of access customer number amount, then consider carrier wave shared channel throughput.At this moment, two strategies are arranged: if turn to target with the maximum of sub-district entire throughput, the carrier wave access priority that then current throughput is low more is high more; If consider that the certain user is relatively poor because of wireless environment, answer the throughput between balanced user, the carrier wave access priority that then current throughput is high more is high more.
Situation two, user ask to insert the HSUPA carrier wave
Can set according to concrete rule, select to investigate in the following measuring amount one and select foundation as carrier wave:
According to the up RTWP of E-PUCH shared channel (Received Total Wide band Power, receive total bandwidth power)/RSCP (Received Signal Code Power, received signal code power)/ISCP (Interference Signal Code Power, Interference Signal Code Power), determine received power, the carrier wave priority that power is more little is high more; Or,
Obtain the HSPA number of users that carrier wave has inserted, the carrier wave priority that number of users is few more is high more; Or,
Obtain the throughput of E-PUCH shared channel, the carrier wave access priority that throughput is low more is high more.
In concrete application scenarios, for the HSPA carrier wave that has disposed HS-PDSCH and E-PUCH shared channel simultaneously, descending can be with reference to the descending strategy of HSDPA carrier wave, up can being used in combination with reference to the up strategy of HSUPA carrier wave.
Based on above-mentioned technical scheme, when carrying out the carrier wave prioritization, the ranking criteria of uplink and downlink be can select respectively, and the setting and the application of the SDCA uplink and downlink factor passed through according to the SDCA algorithm, realize taking all factors into consideration of up-downgoing Sort Priority.
Second portion: in the professional maintenance stage, if the intercarrier load is unbalanced, the user in the carrier wave that load is higher adjusts on the lower carrier wave of load.
During business kept, when reaching certain load balancing trigger condition, when carrier load difference acquired a certain degree, the user in the carrier wave that can load is higher adjusted on the lower carrier wave of load.
The determination methods of carrier load difference is more, is example with carrier wave throughput load, can comprise one or more of following strategy:
1, the absolute value difference of configuration intercarrier throughput when maximum throughput and minimum throughout are worth greater than this, is adjusted to the certain customers on the carrier wave of throughput maximum on the carrier wave of throughput minimum.
2, configuration intercarrier throughput ratio is poor, when two carrier wave throughput ratio differences reach thresholding, the certain customers on the carrier wave of throughput maximum is adjusted on the carrier wave of throughput minimum.
3, the high threshold and the low threshold of configuration intercarrier throughput absolute value, a certain carrier wave throughput is higher than high threshold, and when another carrier wave was lower than low threshold, the certain customers that will be higher than on the carrier wave of high threshold adjusted on the carrier wave that is lower than low threshold.
4, configuration SDCA carrier wave priority factors is poor, promptly consider throughput and power/interference simultaneously, when two carrier wave SDCA sort, when the priority factors difference after the up-downgoing weighting reaches thresholding, the certain customers on the carrier wave of the factor less (priority is lower) are adjusted on the carrier wave of the factor big (priority is higher).When having a plurality of carrier wave, can directly compare the priority factors of two high and minimum carrier waves of priority usually.
When adjusting the user of each intercarrier, can select controlled UE (User Equipment, subscriber equipment) with reference to the application speed of each user's current business, principle makes adjustment back two carrier load equilibriums for adjusting minimum UE.
When adjusting the user, can consider that also two carrier waves exchange user's adjustment.
