Fig. 1 shows the flow chart that a kind of frame of the present invention divides the automatic optimization method of multiplexing structure, and Fig. 2 shows the flow chart that frame in this embodiment divides the automatic optimization method of multiplexing structure, and as can be seen from Figure, the method comprises the following steps:
Step S11: open RNC frame minute multiplex switch, collect the H carrier information;
Step S12: according to collected H carrier information, inquire about the frame minute multiplexed situation of each community H carrier wave, determine the carrier type of community H carrier wave; Described carrier type comprises main carrier and auxiliary carrier wave;
Step S13: adjust threshold range according to the HSDPA number of users of community and user and frame is carried out in community divide multiplexing adjustment.
It is to use to follow on channel at HSDPA-DPCH that frame described in present embodiment divides multiplexing structure, follows channel DPCH frame to divide multiplexing.RNC(Radio Network Controller), radio network controller is a key network element of emerging 3G network, and it is the part of Access Network, for mobile management, call treatment, url management and handover mechanism are provided.The frame of cell level divides the control of multiplexing function limitation in high other RNC of one-level, and each RNC controls all communities below it, and maximum each RNC can arrange 600-800 community.Open RNC frame minute multiplex switch (if do not open RNC frame minute multiplex switch, the frame of cell level divides multiplexing function can not come into force), by collecting the H carrier information, inquiry draws the frame minute multiplexed situation of each community H carrier wave, determine the carrier type of community H carrier wave, i.e. the H carrier wave of distinguishing cell configuration is main carrier configuration or the configuration of auxiliary carrier wave.
In present embodiment, described H carrier information comprises the title of community, the frequency at the scrambler of community, dominant frequency, H carrier wave place, and the existing frame of H carrier wave divides setting, the power of H carrier wave, the active user quantity of community maximum transmission power and H carrier wave etc.After completing the collection of H carrier information, directly by LIST Tcarrier(carrier list) order inquired about just passablely, by the main and auxiliary carrier identification in community of community the inside, just can distinguish carrier type.But, in optimizing, major and minor carrier wave can adjust, therefore the time marquis who uses this function, need to regularly carry out the community training in rotation.
After the carrier type of the H carrier wave of confirming community, according to the carrier type of community H carrier wave, community is set and carries out frame and divide the user of multiplexing adjustment to adjust threshold range, and adjust threshold range according to the HSDPA number of users of community and user and frame is carried out in community divide multiplexing adjustment.
In present embodiment, the HSDPA frame divides multiplexingly to be adjusted according to carrier-grade, and minimum is set to 1 times (be and close), and maximum is set to 4 times, and setting is according to 1 times, and 2 times, 4 times of three modes are arranged.The maximum user's carrying of auxiliary carrier wave is respectively 6,12,24, and main carrier is 5,12,24 H users.
When according to carrier wave configuring condition (H carrier type), the user being set and adjusting thresholding, the thresholding of main carrier is less than a user of auxiliary carrier wave, be minimum value and the maximum that the user of the user of H carrier wave while being main carrier when adjusting the minimum value of threshold range and maximum and being less than respectively the H carrier wave and being auxiliary carrier wave adjusts threshold range, while certainly arranging, maximum can not surpass above-mentioned maximum user's carrying, and minimum value is 0.
It is that 2 times of frames divide multiplexing that the downlink frame that the frame of existing the whole network divides multiplexing structure to be generally 2 times of frame Fen，Ji communities is divided multiplexing structure.Before the frame of present embodiment Zhong Dui community divides multiplexing structure to be adjusted, the downlink frame of community divides multiplexing structure to be 2 times of frames to divide multiplexing, SCCH/SICH in the HSDPA configuration of community is configured to 1 pair, its maximum accessible 12 H users of the next auxiliary carrier wave of this structure, main carrier can be accessed by 12 H users.
In present embodiment, the user adjusts threshold range and comprises that frame divides and close threshold range, frame and divide and keep threshold range and frame to divide the adjustment threshold range; the thresholding of main carrier is less than a user of auxiliary carrier wave; and be provided with amount of redundancy and carry out redundancy protecting (1 user's amount of redundancy during auxiliary carrier wave, 2 user's amount of redundancys during main carrier).When the H carrier wave is auxiliary carrier wave, frame divides that to close threshold range be that 0-5, frame divide that to keep threshold range be 6-11, and frame divides that to adjust threshold range be 12-24.When the H of community carrier wave is main carrier, frame divides that to close threshold range be that 0-4, frame divide that to keep threshold range be 5-10, and frame divides that to adjust threshold range be 11-24.
After setting the user and adjusting threshold range, to adjust threshold range according to the HSDPA number of users of community and user and frame is carried out in community divide multiplexing adjustment, concrete mode is as shown in Fig. 2 and following table, specific as follows:
When the HSDPA of community number of users divides while closing threshold range at frame, close the cell downlink frame and divide multiplexing; When the HSDPA of community number of users, when frame divides the maintenance threshold range, keep the cell downlink frame to divide multiplexing structure constant; When the HSDPA of community number of users divides while adjusting threshold range at frame, to open 2 times of frames of cell uplink and divide multiplexingly, the changing cells downlink frame is divided and is multiplexed with 4 times.
In addition, when conducting frame divides the adjustment of multiplexing structure, should also be noted that adjusting events:
descending 2 times of frames that existing network is used are multiplexing or do not open frame multiplexing the time, up frame is multiplexing is all closed condition, but descendingly open 4 times of frames will to require to open up 2 times of frames multiplexing the time multiplexing simultaneously, can cause because up code is resource-constrained congestedly, cause descendingly having opened 4 times of frames and there is no effect after multiplexing;
Existing the method that frame divides multiplexing structure is set manually, due to only for single subdistrict, unlike the Automatic Optimal program, may to up to a hundred communities, be adjusted simultaneously, therefore the time marquis who manually arranges does not generally do user's migration, consequence can cause being modified the existing voice user in community and data user exactly, call drop and going offline.But owing to being the single subdistrict adjustment, so influence surface is little, can be in the traffic measurement of a day PASS.But when adopting mode of the present invention automatically to adjust, may to up to a hundred communities, be adjusted simultaneously, therefore while modification that frame divides multiplexing structure being carried out in community, (closing the cell downlink frame divides multiplexing, perhaps open 2 times of frames of cell uplink and divide multiplexingly, the changing cells downlink frame is divided while being multiplexed with 4 times) user under the ，Dui community carries out user's migration, moved rear inaccessible community, the modification that frame divides multiplexing structure is carried out in community, after having revised, activation cell.
When the frame of Dui community divides multiplexing structure to modify, the related operational order of parameter adjustment is as shown in the table, and the instruction in this table, parameter and appointment codes are existing order in existing operating system, instruction and parameter.
The theoretical downloading rate single carrier of HSDPA is 2.8Mbps, and the in fact existing time slot transfer point according to 2:4 is configured, and the alone family of general commerce user can reach 1.4-1.6Mbtis/S.If open 2 times of frames, divide, the alone family of Mean Speed only has 1.0-1.2Mbtis/S, and the time marquis burr of 4 times is larger, and alone family on average only has 900K-1.1Mbits/S.Therefore unnecessary frame divides unlatching will have a strong impact on client perception, reduce the income of operator's data service, for example according to unique user, calculate, carry out streaming media service with alone family, 90 minutes, according to 0.0005 yuan/KB of present Mobile data bag, not open respectively the mode that frame divides and open 4 times of frames to divide and calculated, result is as shown in the table:
Method of the present invention, when the multi-user is accessed, at first carry out whether the frame separation structure being optimized to adjustment, can effectively reduce H user by the method congested, improves user awareness, promoted the data service income of operator simultaneously.
Obviously, those skilled in the art can carry out various changes and modification and not break away from the spirit and scope of the present invention the present invention.Like this, if within of the present invention these are revised and modification belongs to the scope of the claims in the present invention and equivalent technology thereof, the present invention also is intended to comprise these changes and modification interior.
