The embodiment of the present invention is by real-time query existing network channel occupation status, judge the service bearer situation of community, accomplish the service bearer ability of real-time analysis community, then by adjustment half rate traffic ratio thresholding and power grade parameter, accomplish rationally to absorb traffic, ensure user's access, reduce congested.
As shown in Figure 1, present embodiments provide a kind of automatic optimization method of special screne community, comprising:
Step 101, selection special screne community, and select to need monitoring (the special period refers to the time that activity is held the special period, by activity start last hour, terminate latter one hour for setting-up time), obtain TCH channel (voice channel) initial configuration number and community existing network power grade (PL) of community.
The TCH channel initial configuration number of this community is read from cell parameter allocation list.
The emitting power grade of power grade Parametric Representation carrier frequency, parameter value is larger, and transmitting power is less.When optimum configurations is " 0 ", represent that the emitting power grade of carrier frequency is maximum, every grade is successively decreased with 2dB.
Power grade inquiry is by with the execution that gives an order:
LST?GTRXDEV：IDTYPE=BYID，CELLID＝X，TRXID=Y
Step 102, per minute or every 30 seconds Automatic inquirying TCH channel occupation status, and TCH channel occupation status is analyzed, calculate K value.
TCH channel occupation status is analyzed: Real-time Obtaining existing network channel occupation status information table, and currently under adding up community have how many TCH channels to be in seizure condition, then be divided by with statistics and this community TCH channel initial configuration number, both can obtain channel seizure ratio K.K value is:
K=TCH channel occupancy number/TCH channel initial configuration number (scope: 0-2)
Wherein, pass through instruction: DSP CHNSTAT:OBJTYPE=CELL, CELLIDTYPE=BYID, CELLID=XX carry out the TCH channel occupancy number of this community of query statistic.
Step 103, judge whether K is less than 0.8, if K<0.8, Automatic inquirying per minute TCH channel occupation status is then set, and judge whether power grade PL adjusted, if adjusted and PL >=0, new power grade PLnew=PL-2 is then set, otherwise new power grade is not set; Otherwise perform next step.K is less than the current configuration in this community of 0.8 explanation and can meets consumers' demand completely, can not affect the normal access of user, therefore can recover the power adjustment before this community.
Power grade is arranged through the execution that gives an order:
SET?GTRXDEV:TRXID=X,POWL=Y
Step 104, judge whether K is more than or equal to 0.8 and is less than 1.2, if 0.8≤K<1.2, Automatic inquirying per minute TCH channel occupation status is then set, and judge whether the TCH traffic thresholding that does is greater than 40, if then adjust TCH traffic to hurry thresholding=40, otherwise do not adjust TCH traffic and to hurry thresholding; Otherwise perform next step.Reduce the TCH traffic thresholding that does and can accelerate the speed that TCH full speed channel transforms to half-rate channel, increase the application percentage of half-rate channel, thus more user can be met access.
Step 105, judge whether K is more than or equal to 1.2 and is less than 1.8, if 1.2≤K<1.8, every 30 seconds Automatic inquirying TCH channel occupation status is then set, and judge whether the TCH traffic thresholding that does is greater than 1, if then adjust TCH traffic to hurry thresholding=1, otherwise do not adjust TCH traffic and to hurry thresholding; Otherwise perform next step.The traffic thresholding that hurries is reduced to 1, and object is in order to the full rate TCH channel this community is all converted into half-rate channel, meets user's access to greatest extent.
Step 106, every 30 seconds Automatic inquirying TCH channel occupation status is set, and judges whether the TCH traffic thresholding that does is greater than 1, to hurry thresholding=1 if then adjust TCH traffic, otherwise do not adjust TCH traffic and to hurry thresholding.The traffic thresholding that hurries is reduced to 1, and object is also in order to the full rate TCH channel this community is all converted into half-rate channel, meets user's access to greatest extent.
Step 107, judge whether power grade is more than or equal to 6, if so, then do not adjust power grade PL; Otherwise PLnew=PL+2 is set.By adjustment above, this special screne community reaches maximum size, cannot access more user again, now for the user that cannot access, should be shared to other community of surrounding, these users are linked in other community and go, solve user further and access problem.
