TD-SCDMA adopt the TDD(time-division duplex) mode, it is possible to the proportioning of dynamic conditioning up-downgoing, support non-symmetrical service preferably. But the sharply increase due to wireless data service, the asymmetry of up-downgoing portfolio highlights day by day. HSPAMX(high-speed packet access signal channel technology) introduce after, the control channel of HSPA business occupies more code channel resource, make HSPA with channel can code channel resource less, limit single carrier access customer number, the traffic channel spatial division multiplexing effect bringing data throughput amount double cannot be played. For solving the problem of the limited and adjoint channel of single carrier access customer number, introduce HSPA and divide multiplexing technology with channel frame, a number of users that can simultaneously carry with channel is made to be increased to 4 by 1, access customer number promotes 4 times, solve the restriction of single carrier access customer number, improve with the special physics channel of DPCH() resource utilization, give full play to the traffic channel spatial division multiplexing advantage bringing data throughput improvement.
HSPA comprises HSDPA(high-speed slender body theory) and the access of HSUPA(high speed uplink packet), HSDPA technology has several new channels to introduce in TD-SCDMA standard:

(2) HS-SCCH(downlink high-speed shared control channel);
(3) HS-SICH(up-high speed shares information channel);
(4) HSDPA-DPCH is with channel;
Frame separation structure is used in HSDPA-DPCH with, on channel, absorbing customer volume as target to increase. With channel multiplexing be utilize the special physics channel of DPCH(in TDD) repeat cycle, repeat length and send skew realize multi-subscriber time shared send, namely the user in multiplexing same code road is every the Repetitionperiod(repeat cycle) individual radio frames sends a secondary data, in succession sends Repetitionlength(and repeats length every time) individual radio frames.
Along with the fast development of mobile communication business, the TD user of China Mobile's development has reached 100,000,000 users in theory, but the data traffic analysis according to every day, and the TD data traffic in a city is only about the 5% of GSM. Therefore to be promoted the data carrying capabilities of TD-SCDMA system, allow the cellphone subscriber can be better, use PS territory business (packet switching service) faster, promote user awareness, increase the data service income of mobile operator. Now the frame of each TD community divides multiplexing all reasonably to use, once substantially not have any amendment after arranging, be only found H user congested after just adjust to and divide with big frame. Once customer volume little after also just do not adjusted (unless leader complain speed of download slow), be rely on manual type to carry out post measure completely, it does not have the advantage of PS territory business in outstanding TD system.

Embodiment
Below in conjunction with Figure of description and embodiment, the present invention is described in further detail.
Fig. 1 shows the schema that a kind of frame of the present invention divides the automatic optimization method of multiplexing structure, and Fig. 2 shows frame in this embodiment and divides the schema of 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 point multiplex switch, collects H carrier wave information;
Step S12: according to collected H carrier wave information, inquire about the frame point multiplexed situation of each community H carrier wave, it is determined that the carrier type of community H carrier wave; Described carrier type comprises main carrier and auxiliary carrier wave;
Step S13: adjust the adjustment that community carries out frame and divide multiplexing by thresholding scope according to the HSDPA number of users of community and user.
Frame described in present embodiment divides multiplexing structure to be used in HSDPA-DPCH with, on channel, namely dividing multiplexing with channel DPCH frame. RNC(RadioNetworkController), namely wireless network control device is a key network element of emerging 3G network, and it is the integral part of connecting network, for providing mobile management, call treatment, url management and handover mechanism. The frame of cell level divides multiplexing function limitation in the control of high other RNC of one-level, and each RNC controls communities all below it, and each RNC maximum can arrange 600-800 community. Open RNC frame point multiplex switch (if not opening RNC frame point multiplex switch, the frame of cell level divides multiplexing function then can not come into force), by collecting H carrier wave information, inquiry draws the frame point multiplexed situation of each community H carrier wave, determining the carrier type of community H carrier wave, namely the H carrier wave configuration of distinguishing cell is main carrier configuration or the configuration of auxiliary carrier wave.
In present embodiment, the title of described H carrier wave information community, the frequency at the scrambler of community, dominant frequency, H carrier wave place, the existing frame of H carrier wave divides setting, the power of H carrier wave, the real-time number of users etc. of community emission maximum power and H carrier wave. After completing the collection of H carrier wave information, directly by LISTTcarrier(carrier list) to carry out inquiry just passable in order, just can distinguish carrier type by the main and auxiliary carrier identification in the community inside community.But in optimizing, major and minor carrier wave can adjust, therefore ask using the time marquis of this function to need regularly to carry out community wheel.
After confirming the carrier type of H carrier wave of community, carrier type according to community H carrier wave arranges community to carry out the user that frame divides multiplexing to adjust and adjusts thresholding scope, and adjusts, according to the HSDPA number of users of community and user, the adjustment that community carries out frame and divide multiplexing by thresholding scope.
In present embodiment, HSDPA frame divides multiplexing to be adjust according to carrier-grade, minimum is set to 1 times (being closedown), maximum is set to 4 times, and setting is according to 1 times, 2 times, and 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.
According to carrier wave configuring condition (H carrier type) arrange user adjust thresholding time, the thresholding of main carrier is less than a user of auxiliary carrier wave, namely H carrier wave be user during main carrier adjust the minimum value of thresholding scope and maximum value to be less than H carrier wave respectively be minimum value and the maximum value that user during auxiliary carrier wave adjusts thresholding scope, when certainly arranging, maximum value can not exceed above-mentioned maximum user carrying, and minimum value is 0.
The frame of existing the whole network divides multiplexing structure to be generally 2 times of frames and divides, and namely the downlink frame of community divides multiplexing structure to be that 2 times of frames divide multiplexing. Before the frame of present embodiment Zhong Dui community divides multiplexing structure to adjust, the downlink frame of community is divided multiplexing structure to be 2 times of frames and is divided multiplexing, it is right that SCCH/SICH in the HSDPA configuration of community is configured to 1, 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, user adjusts thresholding scope and comprises frame and divide and close thresholding scope, frame and divide and keep thresholding scope and frame to divide adjustment thresholding scope; the thresholding of main carrier is less than a user of auxiliary carrier wave; and be provided with redundancy amount and carry out redundancy protecting (during auxiliary carrier wave 1 user's redundancy amount, 2 user's redundancy amounts during main carrier). When H carrier wave is auxiliary carrier wave, frame divides that to close thresholding scope be that 0-5, frame divide and keep thresholding scope to be 6-11, and frame divides adjustment thresholding scope to be 12-24. When the H carrier wave of community is main carrier, frame divides that to close thresholding scope be that 0-4, frame divide and keep thresholding scope to be 5-10, and frame divides adjustment thresholding scope to be 11-24.
Setting after user adjusts thresholding scope, adjusting, according to the HSDPA number of users of community and user, the adjustment that community carries out frame and divide multiplexing by thresholding scope, concrete mode is as shown in Fig. 2 and following table, specific as follows:
When the HSDPA number of users of community divides closedown thresholding scope at frame, close cell downlink frame and divide multiplexing; When the HSDPA number of users of community divides maintenance thresholding scope at frame, cell downlink frame is kept to divide multiplexing structure constant; When the HSDPA number of users of community divides adjustment thresholding scope at frame, opening cell uplink 2 times of frames and divide multiplexing, 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:
When now netting descending 2 times of frame multiplexings of use or do not open frame multiplexing, the frame multiplexing of upper row is all closing condition, but descending will require to open row 2 times of frame multiplexings when opening 4 times of frame multiplexings simultaneously, can cause owing to upper row code is resource-constrained congested, cause descending opened 4 times of frame multiplexings after there is no effect;
Carrying out the inaccessible community of needs time frame divides amendment could revise, then just can come into force in activation cell
Behind inaccessible community, it is necessary to amendment carrier wave is just passable, it is necessary to determine the model of carrier wave is main carrier, auxiliary carrier wave, R4 carrier wave;
Need user under amendment community is carried out user's migration before inaccessible, so needing the PCCPCH power first reducing cell main carrier, by PCCPCH power reduction at least to 60(0.1dbm) wait that user moves to the inaccessible community of ability after on other community afterwards, not so can cause conversation loss, fall line;
The situation of adjustment HSDPA frame separation structure should be too frequent, as one hour adjusts once.
Arrange in the method that frame divides multiplexing structure manually existing, due to only for single subdistrict, up to a hundred communities may not adjusted as Automatic Optimal program simultaneously, therefore the time marquis manually arranged generally does not do user's migration, consequence can cause being modified the existing voice user in community and data user exactly, falls words and falls line. But due to be single subdistrict adjustment, therefore affect face little, can one day traffic statistics in PASS. But when adopting mode of the present invention automatically to adjust, up to a hundred communities may be adjusted simultaneously, therefore community carries out frame divide and (close cell downlink frame and divide multiplexing during the amendment of multiplexing structure, or opening cell uplink 2 times of frames and divide multiplexing, changing cells downlink frame is divided when being multiplexed with 4 times), the user under community is carried out user's migration, inaccessible community after having moved, community is carried out the amendment that frame divides multiplexing structure, after having revised, activation cell.
When dividing multiplexing structure to modify the frame of community, the operational order involved by parameter adjustment is as shown in the table, and instruction in this table, parameter and appointment codes are in existing operating system existing order, instruction and parameter.
The theoretical downloading rate single carrier of HSDPA is 2.8Mbps, in fact existing configures according to the time gap transformation point of 2:4, and general commerce user's single user can reach 1.4-1.6Mbtis/S. If opening 2 times of frames to divide, then mean rate single user only 1.0-1.2Mbtis/S, time marquis's burr of 4 times is bigger, and single user on average only has 900K-1.1Mbits/S. Therefore unnecessary frame divides unlatching will seriously affect client perception, reduce the income of carrier data business, such as calculate according to single user, streaming media service is carried out with single user, 90 minutes, according to now mobile data packet 0.0005 yuan/KB, not opening the mode that frame divides and open 4 times of frames to divide respectively and calculate, result is as shown in the table:
Method of the present invention, when multi-user accesses, first carries out whether frame separation structure being optimized adjustment, can effectively reduce H user by the method congested, it is to increase user awareness, improve the data service income of operator simultaneously.
Obviously, the present invention can be carried out various change and modification and not depart from the spirit and scope of the present invention by the technician of this area. Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technology thereof, then the present invention also is intended to comprise these change and modification.
