Preferred embodiment one

This preferred embodiment provides a method for processing a downlink control channel. This embodiment combines the above-mentioned embodiments and preferred implementation modes thereof. FIG. 4 is a flow chart of a method for processing a downlink control channel according to a preferred embodiment of the present invention, as shown in As shown in Figure 4, the method includes the following steps:

Step S402: The RNC periodically counts the number of dedicated E-DCH users controlled on all HSUPA downlink control channels.

It should be noted that the HSUPA downlink control channel in step S402 is the E-AGCH channel for controlling the dedicated E-DCH user and the E-RGCH/HICH channel for controlling the dedicated E-DCH user.

For the above different channel types of the downlink control channel, the number of dedicated E-DCH users is counted separately for the E-AGCH channel for controlling the dedicated E-DCH user and the E-RGCH/HICH channel for controlling the dedicated E-DCH user. Step S402 includes the following two steps:

Step 1: For the E-AGCH channel for controlling dedicated E-DCH users: the E-AGCH channel allocated by the RNC to the dedicated E-DCH users with this cell as the serving cell fed back by the NodeB in the radio link establishment/reconfiguration/addition response message -AGCH code word to count the number of dedicated E-DCH users controlled on each E-AGCH channel that controls dedicated E-DCH users, and count the dedicated E-DCH users controlled on each E-AGCH channel that controls dedicated E-DCH users The sum of the number of users is the number of dedicated E-DCH users controlled by the E-AGCH channel of all dedicated E-DCH users;

Step 2: For the E-RGCH/HICH channel for controlling the dedicated E-DCH user, the RNC feeds back in the wireless link establishment/reconfiguration/addition response message through the NodeB whether to use this cell as the serving cell or not to serve the cell The E-HICH channel signature allocated by the dedicated E-DCH users of the cell indicates the number of dedicated E-DCH users controlled on the E-RGCH/HICH channel of each dedicated E-DCH user, and each E-RGCH/HICH channel The sum of the number of dedicated E-DCH users controlled by the network is the number of dedicated E-DCH users controlled by all E-RGCH/HICH channels.

It should be noted that since the two types of channels are counted independently, there is no sequence in which the above two steps are performed, and the two steps can be performed according to the needs of the actual system, or only any one of the above steps can be performed.

Step S404: Determine whether the number of dedicated E-DCH users controlled on all HSUPA downlink control channels described in step S402 reaches the threshold for increasing the number of HSUPA downlink control channels, if the judgment result is yes, perform step S408, otherwise, perform step S406 .

Preferably, the threshold for increasing the number of HSUPA downlink control channels in this embodiment is "the maximum number of dedicated E-DCH users that can be carried by all the HSUPA downlink control channels described in 101" minus "all the HSUPA downlink control channels described in 101 The result of subtracting the number of dedicated E-DCH users controlled on the control channel from the number of dedicated E-DCH users controlled on all HSUPA downlink control channels in the previous cycle". Since the number of users of the downlink control channel is counted separately, the threshold of the number of up-regulated control channels corresponding to each type of channel is described as follows:

(1) For the E-AGCH channel of the control-dedicated E-DCH user, use the "number of dedicated E-DCH users controlled on the E-AGCH channel of all control-dedicated E-DCH users" and "the number of all current control-dedicated E-DCH users" counted in 101. The maximum number of dedicated E-DCH users that can be carried by the E-AGCH channel of an E-DCH user" minus "101 Dedicated E-DCH controlled on the E-AGCH channel of all control dedicated E-DCH users in the current period The number of users minus the result of the number of dedicated E-DCH users controlled on the E-AGCH channel of all dedicated E-DCH users counted in the previous period" is compared;

(2) For the E-RGCH/HICH channels that control dedicated E-DCH users, use the "number of dedicated E-DCH users controlled on the E-RGCH/HICH channels of all dedicated E-DCH users" and " The maximum number of dedicated E-DCH users that can be carried by the E-RGCH/HICH channel of all control-dedicated E-DCH users at present" minus "the current cycle statistics of all control-dedicated E-DCH users on the E-RGCH/HICH channel The number of dedicated E-DCH users minus the number of dedicated E-DCH users controlled on the E-RGCH/HICH channel of all dedicated E-DCH users counted in the previous period" is compared.

Step S406: Determine that the result of dividing the number of users currently controlled on all HSUPA downlink control channels in step S402 by "the above-mentioned number of HSUPA downlink control channels in 101 is reduced by one" is less than or equal to the threshold of the number of users for reducing the number of HSUPA downlink control channels and in S401 The number of the current HSUPA downlink control channels is not 0 after being reduced by one. If the judgment result is yes, execute step S410, otherwise, execute step S412.

It should be noted that the down-regulation step in this embodiment is 1, so dividing the number of all users by "the above-mentioned number of HSUPA downlink control channels is reduced by one" is to determine the down-regulation operation in the number of channels, and the step size is 1 , it is judged whether the current number of users can meet the carrying capacity of the downlink data channel after the downlink operation.

According to different channel classifications, step S406 can be divided into the following two steps:

Step 1: for controlling the E-AGCH channel of the dedicated E-DCH user, divide the number of dedicated E-DCH users controlled on the E-AGCH channel of all control dedicated E-DCH users counted in 101 by (control the dedicated E-DCH The user's E-AGCH channel number-1) is compared with the E-AGCH channel number user number threshold of the down-regulation control dedicated E-DCH user;

Step 2: for controlling the E-RGCH/HICH channel of the dedicated E-DCH user, divide the number of dedicated E-DCH users controlled on the E-RGCH/HICH channel of all control dedicated E-DCH users counted in 101 by (control The number of E-RGCH/HICH channels of the dedicated E-DCH user - 1) is compared with the threshold of the number of E-RGCH/HICH channels of the dedicated E-DCH user for down-regulation.

It should be noted that since the two types of channels are counted independently, there is no sequence in which the above two steps are performed, and the two steps can be performed according to the needs of the actual system, or only any one of the above steps can be performed.

Step S408, increase the number of HSUPA downlink control channels in step S402.

Step S410, reducing the number of HSUPA downlink control channels mentioned in step 101.

Step S412, do not adjust the number of HSUPA downlink control channels mentioned above in S401.

Through this preferred embodiment, when the number of dedicated E-DCH users carried on the E-AGCH channel for controlling dedicated E-DCH users or the E-RGCH/HICH channel for controlling dedicated E-DCH users exceeds a preset threshold value, the RNC Actively increase the number of E-AGCH channels for controlling dedicated E-DCH users or E-RGCH/HICH channels for controlling dedicated E-DCH users; when controlling E-AGCH channels for dedicated E-DCH users or controlling dedicated E-DCH users When the number of dedicated E-DCH users carried on the E-RGCH/HICH channel is lower than the preset threshold value, the RNC will actively reduce the E-AGCH channel for controlling dedicated E-DCH users or the E-AGCH channel for controlling dedicated E-DCH users. - Channel number of RGCH/HICH channels.

The method comprises the steps of:

Step S502: The RNC counts the number of HSUPA users carried by all E-AGCH channels in the current cell every 5 seconds. A total of 16 HSUPA users in the RNC statistics cell in the last cycle use this cell as the serving cell, that is, the E-AGCH channel controls a total of 16 HSUPA users; a total of 17 users in the current cycle RNC statistics cell use this cell as the serving cell, namely The E-AGCH channel controls a total of 17 HSUPA users; and/or

The RNC counts the number of HSUPA users carried by all E-RGCH/HICH channels in the current cell every 5 seconds. In the last cycle, the RNC counted that the NodeB in the cell assigned the signature of the E-HICH channel to 18 HSUPA users, that is, the E-RGCH/HICH channel controlled a total of 18 HSUPA users; in the current cycle, the RNC counted that the NodeB in the cell had 19 HSUPA users. The user distributes the signature of the E-HICH channel, that is, the E-RGCH/HICH channel controls a total of 19 HSUPA users.

In this embodiment, the user threshold for reducing the number of E-AGCH channels is 18 users for each E-AGCH channel. The user threshold for reducing the number of E-RGCH/HICH channels is 18 users per E-RGCH/HICH channel. The above threshold can be set according to system requirements.

Step S504: According to the above information, the RNC decides whether to increase or decrease the number of downlink control channels.

For different channel classifications, step S404 includes the following two aspects:

(1) According to the above information, whether the RNC judges needs to increase or decrease the E-AGCH channel, this implementation mode is specifically realized through the following steps:

Step 1: According to the statistics of RNC, the E-AGCH channel controlled 16 HSUPA users in the last period, and the E-AGCH channel controlled 17 HSUPA users in the current period.

Step 2: The number of HSUPA users controlled by the E-AGCH channel in the current period is 17 minus the number of HSUPA users controlled by the E-AGCH channel in the previous period. The result of 17 HSUPA users is 18 HSUPA users, which is smaller than the maximum number of 20 HSUPA users that can be carried by all E-AGCH channels of the cell. Therefore, the number of E-AGCH channels cannot be adjusted up.

Step 3: Further judgment: the result of subtracting one from the current E-AGCH channel number is 0. Therefore, the number of E-AGCH channels cannot be lowered, and the current number of E-AGCH channels remains unchanged.

(2) According to the above information, the RNC judges whether to increase or decrease the E-RGCH/HICH channel. This embodiment is specifically implemented through the following steps:

Step 1: According to the statistics of RNC, the E-RGCH/HICH channel controlled 18 HSUPA users in the last period, and the E-RGCH/HICH channel controlled 19 HSUPA users in the current period;

Step 2: The number of HSUPA users controlled by the E-RGCH/HICH channel in the current period is 19 minus the number of HSUPA users controlled by the E-RGCH/HICH channel in the previous period. The result is 18 users, and this result is added to the current period E - The result of 19 HSUPA users controlled by the RGCH/HICH channel is 20 HSUPA users, which is equal to the maximum number of 20 HSUPA users that can be carried by all E-RGCH/HICH channels in the cell. Therefore, the number of E-RGCH/HICH channels is increased.

Each E-RGCH/HICH channel can carry up to 20 HSUPA users. The method comprises the steps of:

Step S602: The RNC counts the number of HSUPA users carried by all E-AGCH channels in the current cell every 5 seconds. A total of 22 HSUPA users in the RNC statistics cell in the last cycle use this cell as the serving cell, that is, the E-AGCH channel controls a total of 22 HSUPA users; a total of 18 users in the RNC statistics cell in the current cycle use this cell as the serving cell, namely The E-AGCH channel controls a total of 18 HSUPA users; and/or

The RNC counts the number of HSUPA users carried by all E-RGCH/HICH channels in the current cell every 5 seconds. In the last cycle, the RNC counted that the NodeB in the cell assigned the signature of the E-HICH channel to 22 HSUPA users, that is, the E-RGCH/HICH channel controlled a total of 22 HSUPA users; in the current cycle, the RNC counted that the NodeB in the cell has 18 HSUPA users. The user distributes the signature of the E-HICH channel, that is, the E-RGCH/HICH channel controls 18 HSUPA users in total.

In this embodiment, the user threshold for reducing the number of E-AGCH channels is 18 users for each E-AGCH channel. The user threshold for reducing the number of E-RGCH/HICH channels is 18 users per E-RGCH/HICH channel. The above threshold can be set according to system requirements.

Step S604: According to the above information, the RNC decides whether to increase or decrease the number of downlink control channels.

For different channel classifications, step S504 includes the following two aspects:

(1) According to the above information, whether the RNC judges needs to increase or decrease the E-AGCH channel, this implementation mode is specifically realized through the following steps:

Step 1: According to the statistics of RNC, the E-AGCH channel controlled 22 HSUPA users in the last period, and the E-AGCH channel controlled 18 HSUPA users in the current period.

Step 2: The number of HSUPA users controlled by the E-AGCH channel in the current period is 17 minus the number of HSUPA users controlled by the E-AGCH channel in the previous period. The result is -5 HSUPA users, and this result is added to the E-AGCH channel in the current period The result of the number of controlled HSUPA users being 17 is 12 HSUPA users, which is smaller than the maximum number of 40 HSUPA users that all E-AGCH channels of the cell can carry. Therefore, the number of E-AGCH channels cannot be adjusted up.

Step 3: Further judgment: the number of users controlled by the current E-AGCH channel is divided by 17 by the number of the current E-AGCH channel, which is 1, and the result is 17 HSUPA users, which is less than the threshold value 18 for lowering the number of E-AGCH channels. Moreover, the number of the current E-AGCH channel decreases by one and is greater than 0. Therefore, the number of E-AGCH channels is lowered.

(2) According to the above information, the RNC judges whether to increase or decrease the E-RGCH/HICH channel. This embodiment is specifically implemented through the following steps:

Step 1: According to the statistics of RNC, the E-RGCH/HICH channel controlled 22 HSUPA users in the last period, and the E-RGCH/HICH channel controlled 18 HSUPA users in the current period;

Step 2: The number of HSUPA users controlled by the E-RGCH/HICH channel in the current period is 17 minus the number of HSUPA users controlled by the E-RGCH/HICH channel in the previous period. The result is -5 HSUPA users, and this result is added to the current period The number of HSUPA users controlled by the E-RGCH/HICH channel is 17, resulting in 12 HSUPA users, which is smaller than the maximum number of HSUPA users of 40 that can be carried by all E-AGCH channels in the cell. Therefore, the number of E-AGCH channels cannot be adjusted up.

Step 3: Further judgment: the number of users controlled by the current E-RGCH/HICH channel is divided by 17 and the number of current E-RGCH/HICH channels is reduced by one, that is, the result is 17 HSUPA users, which is less than the number of down-regulated E-RGCH/HICH channels The threshold value is 18, and the number of the current E-RGCH/HICH channel decreases by one more than 0. Therefore, the number of E-AGCH channels is lowered.
