Preferred embodiment one
This preferred embodiment provides a kind of processing method of down control channel; Present embodiment has combined the foregoing description and preferred implementation wherein; Fig. 4 is the flow chart of the processing method of down control channel according to the preferred embodiment of the invention, and as shown in Figure 4, this method comprises the steps:
The special-purpose E-DCH number of users of controlling on all HSUPA down control channels of step S402:RNC periodic statistics.
Need to prove that the HSUPA down control channel among the step S402 is the special-purpose E-DCH user's of control E-AGCH channel, and the E-RGCH/HICH channel of controlling special-purpose E-DCH user.
For the above-mentioned different channel kind of down control channel, special-purpose E-DCH number of users is added up respectively with the special-purpose E-DCH user's of control E-RGCH/HICH channel for the special-purpose E-DCH user's of control E-AGCH channel.Step S402 comprises following two steps:
Step 1: for the special-purpose E-DCH user's of control E-AGCH channel: RNC through NodeB in Radio Link foundations/reprovision/increases response message, feed back for being that the E-AGCH code word that the special-purpose E-DCH user of Serving cell distributes is added up the special-purpose E-DCH number of users of controlling on every special-purpose E-DCH user's of control the E-AGCH channel with this sub-district, control the special-purpose E-DCH number of users addition of controlling on special-purpose E-DCH user's the E-AGCH channel with every and be the special-purpose E-DCH number of users that all E-AGCH channels of controlling special-purpose E-DCH user are controlled;
Step 2: for the special-purpose E-DCH user's of control E-RGCH/HICH channel; The E-HICH channel for to be Serving cell with this sub-district distribute with the special-purpose E-DCH user who with this sub-district is not Serving cell that RNC feeds back in Radio Link foundation/reprovision/increase response message through NodeB is signed and is represented the special-purpose E-DCH number of users controlled on every special-purpose E-DCH user's of control the E-RGCH/HICH channel, and the addition of the special-purpose E-DCH number of users of controlling on every E-RGCH/HICH channel is the special-purpose E-DCH number of users that all E-RGCH/HICH channels are controlled.
Need to prove,,, and can carry out two steps, perhaps only carry out any in the above-mentioned steps according to the needs of real system so above-mentioned two steps do not have the sequencing of execution because two types of channels are independent statistics.
Step S404: whether the special-purpose E-DCH number of users of controlling on all the HSUPA down control channels described in the determining step S402 reaches the thresholding that raises HSUPA down control channel quantity; If judged result is for being; Execution in step S408, otherwise, execution in step S406.
Preferably, the thresholding of the rise HSUPA down control channel quantity in the present embodiment deducts the result of " result that the special-purpose E-DCH number of users of controlling on all the HSUPA down control channels described in 101 deducts the special-purpose E-DCH number of users of controlling on all HSUPA down control channels of one-period statistics " for " the maximum special-purpose E-DCH number of users that 101 described all HSUPA down control channels can carry ".Because the number of users of down control channel is added up respectively, as follows corresponding to the thresholding explanation of the rise control channel quantity of each type channel:
(1) to controlling special-purpose E-DCH user's E-AGCH channel, with " all control the special-purpose E-DCH number of users of controlling on special-purpose E-DCH user's the E-AGCH channel " of statistics in 101 and " current all control the maximum special-purpose E-DCH number of users that special-purpose E-DCH user's E-AGCH channel can carry " deduct " current period described in 101 all control that the special-purpose E-DCH number of users of controlling on special-purpose E-DCH user's the E-AGCH channel deducts that one-period adds up all control the result of the special-purpose E-DCH number of users of controlling on special-purpose E-DCH user's the E-AGCH channel " the result compare;
(2) to controlling special-purpose E-DCH user's E-RGCH/HICH channel, with " all control the special-purpose E-DCH number of users controlled on special-purpose E-DCH user's the E-RGCH/HICH channel " with " of statistics in 101 current all control the maximum special-purpose E-DCH number of users that special-purpose E-DCH user's E-RGCH/HICH channel can carry " deduct " and current period add up all control that the special-purpose E-DCH number of users of controlling on special-purpose E-DCH user's the E-RGCH/HICH channel deducts that one-period adds up all control the result of the special-purpose E-DCH number of users of controlling on special-purpose E-DCH user's the E-RGCH/HICH channel " the result compare.
Step S406: the number of users of controlling on current all HSUPA down control channels among the determining step S402 is not 0 divided by the result of " in 101 above-mentioned HSUPA down control channel decreased number one " smaller or equal to number after of the number of users thresholding of downward modulation HSUPA down control channel number and the current HSUPA down control channel decreased number described in the S401.If judged result is for being, execution in step S410, otherwise, execution in step S412.
Need to prove; Downward modulation step-length in the present embodiment is 1; So with all numbers of users divided by " one of above-mentioned HSUPA down control channel decreased number "; Be to reduce operation at channel quantity, and step-length is 1 o'clock, judges whether active user's number can satisfy the bearing capacity of the downstream data channel after the downward modulation operation in order to confirm.
According to different channel classifications, step S406 can be divided into following two steps:
Step 1:, control E-AGCH channel number number of users thresholding that the special-purpose E-DCH number of users controlled on special-purpose E-DCH user's the E-AGCH channel controls special-purpose E-DCH user divided by (controlling special-purpose E-DCH user's E-AGCH channel number-1) and downward modulation with all of statistics in 101 and compare for the special-purpose E-DCH user's of control E-AGCH channel;
Step 2:, control E-RGCH/HICH channel number number of users thresholding that the special-purpose E-DCH number of users controlled on special-purpose E-DCH user's the E-RGCH/HICH channel controls special-purpose E-DCH user divided by (controlling special-purpose E-DCH user's the E-RGCH/HICH number of channel-1) and downward modulation with all of statistics in 101 and compare for the special-purpose E-DCH user's of control E-RGCH/HICH channel.
Need to prove,,, and can carry out two steps, perhaps only carry out any in the above-mentioned steps according to the needs of real system so above-mentioned two steps do not have the sequencing of execution because two types of channels are independent statistics.
Step S408, the number of HSUPA down control channel among the increase step S402.
Step S410 reduces the HSUPA down control channel number described in 101.
Step S412 does not adjust the quantity of HSUPA down control channel above-mentioned among the S401.
Through this preferred embodiment; When the special-purpose E-DCH number of users that carries on special-purpose E-DCH user's the E-RGCH/HICH channel when the special-purpose E-DCH user's of control E-AGCH channel or control surpassed threshold value in advance, RNC initiatively increased the special-purpose E-DCH user's of control E-AGCH channel or controls the channel number of special-purpose E-DCH user's E-RGCH/HICH channel; When the special-purpose E-DCH user's of control E-AGCH channel or when controlling the special-purpose E-DCH number of users that carries on special-purpose E-DCH user's the E-RGCH/HICH channel and being lower than predefined threshold value, RNC initiatively reduces the special-purpose E-DCH user's of control E-AGCH channel or controls the channel number of special-purpose E-DCH user's E-RGCH/HICH channel.
