Description
Technical field
The present invention relates to communication technical field, more particularly to a kind of method of adjustment of frame division multiplexing mode of adjoint channel and
Device.
Background technology
TD SDMA（TD-SCDMA, Time Division Synchronous CDMA）System is using shared
Time division duplex（TDD, Time Division Duplex）Mode, the proportioning of uplink and downlink timeslot can be dynamically adjusted, so as to preferably
Support non-symmetrical service in ground.But because the progressively popularization of smart mobile phone causes data service to sharply increase, up-downgoing portfolio
Asymmetry still increasingly highlight, further, since TD-SCDMA system itself have to have be adapted to transmitting data service one
A little characteristics, such as high data volume, high sudden, high reliability, therefore in the evolution of 3rd generation mobile communication technology,
Important enhancing technology a --- high-speed downlink packet access is introduced in 3GPP Release5 Version Specs
（HSDPA, High-Speed Downlink Packet Access）.HSDPA technologies obtain in TD-SCDMA system at present
The application of certain scale is arrived, the data service of cell is mainly just carried on HSDPA carrier waves.Summary is got up, and HSDPA carrier waves are held
Carrying data service has following features：
1st, it is descending to use high speed shared data Traffic Channel（HS-PDSCH）User data is carried, meanwhile, use 3GPP
Release4（R4）DPCH channels in Version Spec（I.e. with channel）Carrier signaling；And the up DPCH letters then used in R4
Road（With channel）Carry user data and signaling, transmission rate are relatively low.
2nd, number of users corresponding to the data service of HSDPA carriers carries is limited to channel resource.
For example as shown in figure 1, general in TD-SCDMA system use 2：4 uplink and downlink timeslot proportioning, so,
2 pairs of downlink high-speed shared control channels are configured on HSDPA carrier waves（HS-SCCH）Information channel is shared with up-high speed（HS-
SICH）In the case of control channel, if being not turned on channel frame division multiplexing function, using channel configuration as shown in Figure 1
The HSDPA carrier waves of mode are at most only capable of accessing 6 users.
It should be noted that above-mentioned " adjoint channel frame division multiplexing " is drawn first to solve single carrier access customer number
A kind of technology entered, it is used for so that multiple users can be with frame point（That is the time-division）Multiplexing is with channel.At present, it is general with channel
There are 2 times of frame division multiplexings（I.e. 2 user's frame division multiplexings 1 are with channel）With 4 times of frame division multiplexings（That is 4 user's frame division multiplexings 1
With channel）Both modes, i.e., it can be generally 2 or 4 with the frame division multiplexing multiple of channel.
3rd, the number of users of HSDPA carriers carries is more, and the average uplink/downlink transmission rate of unique user is lower.
For example when using HSDPA carrier wave configuration modes as shown in Figure 1, divide multiplexed situation with channel frame different
Under, the average uplink/downlink transmission rate of maximum number of user and single user that single HSDPA carrier waves can carry is as shown in table 1 below.Due to
According to configuration mode as shown in Figure 1, the up-downgoing of HSDPA carrier waves with running time-frequency resource shared by channel ratio about 2：1, so as to phase
The ratio for the up-downgoing frame division multiplexing multiple answered can set 1：2.
Table 1：
It can be seen from upper table 1 maximum that HSDPA carrier waves can carry is directly affects with the frame division multiplexing multiple of channel
Number of users.
At present, opened in local hot spot areas with the frame division multiplexing function of channel, but corresponding frame division multiplexing multiple
Often it is arranged to fixed value；Or the frame division multiplexing times can also dynamically be adjusted according to the number of users of HSDPA carriers carries
Number.Such as：When the number of users that carrier wave is carried is less than 6, can be not turned on channel frame division multiplexing function；And work as number of users
When being less than 12 more than 6,2 times of frame division multiplexing functions of descending adjoint channel can be opened（Use frame division multiplexing multiple 2）；Enter one
Step ground, when number of users is more than 12,4 times of frame division multiplexing functions of descending adjoint channel can be opened（I.e. using frame division multiplexing times
Number 4）.
The unlatching of frame division multiplexing function can improve the number of users of single HSDPA carriers carries, but with up adjoint channel
The unlatching of frame division multiplexing function is opened, the uplink transmission rate of each user can be directly influenced.Due to same cell in existing network
Larger difference be present to the demand of transmission rate in different user, such as：Use instant messaging class business（Such as use instant messaging work
Have QQ and carry out text chat）User it is smaller to transmission rate requirements, and carry out the user of software download to transmission rate requirements
It is then larger, therefore, directly set using the actual demand for not differentiating between user in the prior art frame division multiplexing multiple or according to
The number of users of HSDPA carriers carries dynamically adjusts the mode of the frame division multiplexing multiple, poor there is flexibility, it is difficult to meet
The problem of actual demand.

Family the direction transmission rate, the frame division multiplexing mode of adjoint channel being transmitted as adjustment according to the direction according to
According to, substantially increase with channel frame division multiplexing mode adjustment mode flexibility.And the program can also be directed to and possess difference
The user of transmission rate realizes and adjusted respectively.
Embodiments of the invention are illustrated below in conjunction with Figure of description, it will be appreciated that implementation described herein
Example is merely to illustrate and explain the present invention, and is not intended to limit the invention.And in the case where not conflicting, the reality in this explanation
Applying the feature in example and embodiment can be combined with each other.
The embodiment of the present invention provides a kind of method of adjustment of the frame division multiplexing mode of adjoint channel first, this method it is specific
Implementation process schematic diagram is as shown in Fig. 2 mainly comprise the steps：
Step 21, code resource utilization of the high-speed downlink packet access HSDPA carrier waves in certain transmission direction is determined,
And with the user that the HSDPA carrier waves are carried the direction transmission rate；
Wherein, certain transmission direction described here both can be up direction or down direction.
In addition, the user that the user that the HSDPA carrier waves are carried, which can be the HSDPA carrier waves, to be carried, can also
It is multiple even whole users that the HSDPA carrier waves are carried.In the embodiment of the present invention, the HSDPA carrier waves institute is preferably determined
Mode of the whole users of carrying in the transmission rate of the direction.
Step 22, according to the code resource utilization and transmission rate determined, in the user carried from HSDPA carrier waves,
Determine the user of the frame division multiplexing mode of adjoint channel to be adjusted；
Due to being often when the code resource utilization of HSDPA carrier waves reaches a certain size in actual applications, can just hold
Open the frame division multiplexing function with channel（With channel information i.e. in the way of frame division multiplexing）.Therefore, this hair
Currently whether can be necessary to carry out according to the code resource utilization for the HSDPA carrier waves determined, judgement first in bright embodiment
With the adjustment of the frame division multiplexing mode of channel.So as to the use only when judged result is to be, just carried according to HSDPA carrier waves
Family determines the frame point of adjoint channel to be adjusted in the transmission rate of certain transmission direction, the user carried from HSDPA carrier waves
The user of multiplex mode.
Specifically, whether default code resource utilization scope can be in by the code resource utilization for judging to determine
Mode, come judge whether need adjust with channel frame division multiplexing mode.If judge the code resource utilization determined
In default code resource utilization scope, then judge to need to adjust the frame division multiplexing mode with channel；Otherwise, then judge not
Need to adjust the frame division multiplexing mode with channel.
When determining that the code resource utilization is in default code resource utilization scope, judge to need described in adjustment
With the frame division multiplexing mode of channel；Otherwise, judgement need not adjust the frame division multiplexing mode of the adjoint channel.
Step 23, adjustment is arranged on HSDPA carrier waves and carried the user that determines and according to the specific transmission side
To the frame division multiplexing mode for the adjoint channel being transmitted.
For the specific implementation of step 23, different code resource utilizations, transmission rate can be pre-set
With the corresponding relation of the frame division multiplexing multiple with channel.Based on the corresponding relation, it is possible to provided according to the code actually determined
Source utilization rate and the user that determines choose corresponding frame division multiplexing multiple in the transmission rate of certain transmission direction.Pass through ratio
Compared with the frame division multiplexing multiple of selection and with the current frame division multiplexing multiple of channel, it is possible to it is determined that multiple to the frame point with channel
With the adjustment mode of multiple（Such as tune up or turn down）, so as to realize the adjustment to the frame division multiplexing mode with channel.
In the embodiment of the present invention, if assuming, the code resource utilization described in above-mentioned default corresponding relation is represented with x, transmitted
Speed represents that then x, y and a kind of specific corresponding relation of frame division multiplexing mode are referred to shown in table 2 below with y.In the table 2,
A1, A2, A3 are respectively first yard of resource utilization threshold value, second code resource utilization threshold value and third yard resource utilization
Threshold value；And B1, B2 are respectively then the first transmission rate threshold value, the second transmission rate threshold value, and A1 be present<A2<A3, B1
>B2。
Table 2：
| Code resource utilization | Transmission rate | Frame division multiplexing mode |
| x≥A1 | y<B1 | 2 times of frame division multiplexing modes |
| x≥A2 | B2≤y<B1 | 2 times of frame division multiplexing modes |
| x≥A2 | y<B2 | 4 times of frame division multiplexing modes |
| x≥A3 | y<B2 | 4 times of frame division multiplexing modes |
| x≥A3 | B2≤y<B1 | 2 times of frame division multiplexing modes |
| x≥A3 | y≥B1 | 2 times of frame division multiplexing modes |
Wherein, above-mentioned B1 can be, but not limited to as 8kbps, and the second transmission rate threshold value then can be, but not limited to for
4kbps。
Based on upper table 2, if assuming the up code resource utilization x >=A2 of HSDPA carrier waves determined, and assume to be somebody's turn to do
All users that HSDPA carrier waves are carried exist in the transmission rate of up direction and meet B2≤y respectively<B1、y<B2 and
y>B1 transmission rate.So, due to according to upper table, x >=A2 and B2≤y can be inquired<Frame division multiplexing mode corresponding to B1
For " 2 times of frame division multiplexing modes ", x >=A2 and y<Frame division multiplexing mode corresponding to B2 is " 4 times of frame division multiplexing modes ", together
When, it is impossible to inquire x >=A2 and y>Frame division multiplexing mode corresponding to B1.Therefore, the set-up procedure next performed can
Think：For meeting B2≤y<B1 user, it can will carry the frame division multiplexing mode of the adjoint channel of the information of those users
It is adjusted to 2 times of frame division multiplexing modes；For meeting y<B2 user, it can will carry the adjoint channel of the information of those users
Frame division multiplexing mode is adjusted to 4 times of frame division multiplexing modes；And for meeting y>B1 user, it is difficult because its transmission rate is larger
To tolerate that other users share the adjoint channel of its information of carrying, so as to carry the frame of the adjoint channel of the information of the certain customers
Divide multiplex mode can be without adjustment.However, for meeting y>B1 user, if carrying the adjoint letter of the information of those users
The frame division multiplexing mode in road is currently more times of frame division multiplexing modes, then in order to ensure to meet its transmission rate, can close carrying
The frame division multiplexing function of the adjoint channel of its information.
It should be noted that in the embodiment of the present invention, performing what the determination HSDPA carrier waves described in step 21 were carried
User is before the step for transmission rate of the direction, if finding, the code resource utilization of the HSDPA carrier waves is larger, that
, in order that more users can be carried by obtaining the HSDPA carrier waves, suitably larger transmission rate can be adjusted,
So that larger transmission rate reduces.Then, then user that the follow-up determination HSDPA carrier waves are carried is performed in the direction
The operation of transmission rate.
In a kind of specific embodiment, in order to reach the purpose for reducing larger transmission rate, the embodiment of the present invention
Can perform transmission rate of the user that is carried of determination HSDPA carrier waves described in step 21 in the direction the step for it
Before, perform following step：
First, it is determined that whether code resource utilization of the HSDPA carrier waves determined in certain transmission direction is more than in advance
If code resource utilization threshold value；
Then, judged result for be when, from be arranged on the HSDPA carrier waves and according to the certain transmission direction carry out
The user that the adjoint channel of transmission is carried is in the transmission rate of the direction, it is determined that the biography more than Preset Transfer rate threshold value
Defeated speed；
Finally, the transmission rate that will be greater than Preset Transfer rate threshold value is adjusted to consistent with defined transmission rate.
For example the up code resource utilization of the HSDPA carrier waves is more than default up code resource utilization if judging
Threshold value, then the uplink transmission rate more than 16kbps can be adjusted, after being adjusted to 16kpbs, then based on setting
The transmission rate for each user that up adjoint channel on the HSDPA carrier waves is carried and the current up code utilization of resources
Rate, perform the adjustment operation of the frame division multiplexing mode of the up adjoint channel.
From such scheme provided in an embodiment of the present invention, the program is the actual transfer rate and HSDPA with user
The actual load of carrier wave adjusts the frame division multiplexing mode with channel, so as to meet the actual need of different user well
Ask, solve and asked using flexibility is poor existing for the Adjusted Option of the frame division multiplexing mode of adjoint channel of the prior art
Topic.
The application flow of such scheme in practice is introduced in detail below.
A kind of schematic diagram of the specific implementation flow of this programme in actual applications is as shown in figure 3, including following main steps
Suddenly：
Step 31, it is assumed that the number of users that HSDPA carrier waves are initially carried is less, so as to which up code resource utilization is relatively low
When, the up adjoint channel of all users is not turned on frame division multiplexing function, then, if it is follow-up want to dynamic adjust it is up
The frame division multiplexing mode of adjoint channel, then policer operation of the base station execution to the up code resource utilization of HSDPA carrier waves, together
When, base station also monitors the uplink transmission rate for the user that the HSDPA carrier waves are carried.
Step 32, base station judges whether the up code resource utilization x for monitoring HSDPA carrier waves meets to be more than or equal to thresholding
A1, and otherwise continue executing with the up code resource of monitoring HSDPA carrier waves in judged result when being, further to perform step 33
The operation of utilization rate；
Step 33, base station judges whether that uplink transmission rate y meets to be less than thresholding B1（Such as 8kbps）User, if
It is judged as existing, then performs step 34；Otherwise, for upstream rate is unsatisfactory for the user less than B1, then base station is not turned on
Carry the frame division multiplexing function of the up adjoint channel of the information of the certain customers（Hereinafter referred to as open the frame of up adjoint channel
Divide multiplexing function）.
Step 34, for meeting that users of the uplink transmission rate y less than thresholding B1 opens 2 times of frames point of up adjoint channel
Function is multiplexed, so as to which base station sends the notification message for using 2 times of frame division multiplexing modes to send information to the certain customers；
Step 35, for small rate users（That is the less user of uplink transmission rate, if uplink transmission rate is less than B1
User）After 2 times of frame division multiplexing functions of up unlatching, base station judges whether the up code resource utilization x monitored again is more than
Equal to thresholding A2（A2>A1）, if the determination result is YES, then step 37 is performed, if judged result is no, performs step 36.
Step 36, judge whether up code resource utilization x is less than thresholding A1 '（A1’<A1）If judged result is,
The small rate users of frame division multiplexing function no longer for being not yet turned on up adjoint channel open the function；Otherwise, then perform
Step 33, i.e., 2 times of frame division multiplexing functions of up adjoint channel are opened only for small rate users；
Step 37, it is less than thresholding B2 for uplink transmission rate y（Such as 4kbps, and B2<B1）User open it is up adjoint
4 times of frame division multiplexing functions of channel, it is more than or equal to thresholding B2 for uplink transmission rate y but is less than in thresholding B1 user's unlatching
2 times of frame division multiplexing functions of the adjoint channel of row, the frame division multiplexing function of up adjoint channel is not turned on for other rate users.
It should be noted that the content being located in Fig. 3 in step 37 lower broken line frame is the specific implementation of step 37.
Step 38, by performing above-mentioned steps 37, and realize and open 2 times, 4 times of frames point for different small rate users are up
After being multiplexed function, base station continues to judge whether the up code resource utilization x monitored again is more than or equal to thresholding A3, if judging
As a result it is yes, then performs step 310, otherwise, performs step 39；
Step 39, judge whether up code resource utilization x is less than thresholding A2 '（A1<=A2’<A2）If judged result is
It is that then the small rate users of the frame division multiplexing function no longer for being not yet turned on up adjoint channel open the function；Otherwise, then
Step 37 is performed, 2 times or 4 times of frame division multiplexing functions are opened for different small rate users are up to realize.
Step 310, Different Strategies are taken for possessing the user of different uplink transmission rates：
It is less than thresholding B2 for uplink transmission rate y（Such as 4kbps）User open 4 times of frames point of up adjoint channel and answer
Use function；2 times of up adjoint channel are opened for the user that uplink transmission rate y is more than or equal to thresholding B2 but is less than thresholding B1
Frame division multiplexing function；It then can control to carry out reduction of speed for possessing the user of other uplink transmission rates（Can be according to uplink
The order of speed from high to low, each larger uplink transmission rate is reduced successively）, possess higher uplink transmission rate when all
During with having dropped down to 16kbps per family, to meet to cause the more users of HSDPA carriers carries, it can be dropped to for transmission rate
16kbps user opens 2 times of frame division multiplexing functions of up adjoint channel.
It should be noted that the content being located in Fig. 3 in step 310 lower broken line frame is the specific implementation side of step 310
Formula.
Step 311, by perform step 310 realize for possess the users of different uplink transmission rates use it is different
After frame division multiplexing function adjustable strategies, whether the up code resource utilization x for continuing the HSDPA carrier waves that judgement monitors again is small
In thresholding A3 ' (A2<=A3’<A3), if the determination result is YES, then no longer it is directed to the frame division multiplexing for being not yet turned on up adjoint channel
The user of function opens the function, and and then perform step 39, and if judged result be no, execution step 310.
