Description
Technical field
A kind of the present invention relates to communication technical field, more particularly to method and apparatus for determining data service bearing mode.
Background technology
In 3G systems, there are two kinds of data transmission methods of circuit domain (CS domains) and packet-switched domain (ps domain).With
The issue of 3GPP Release5 versions, ps domain Deta bearer increased high speed downlink packet in addition to original R4 bearing modes
This bearing mode of business (HSDPA), is characterized in, by introducing new technological means, being greatly improved downlink grouping traffic
Message transmission rate.Similarly, high speed up packet service (HSUPA) bearing mode is introduced in 3GPP R7 versions, its
High speed shared channels are introduced in up direction, the uplink transmission rate of user is lifted.When a user equipment (UE) had both adopted HSDPA
When bearing mode adopts HSUPA bearing modes again, the UE can be claimed to employ HSPA bearing modes.
At present, in order to provide the user with higher data traffic transmission speed, in the feelings that Internet resources are allowed and UE is supported
Under condition, the data service of user adopts HSDPA bearing modes and HSUPA bearing modes, specifically refers to Fig. 1.
Fig. 1 is the method flow diagram of determination data service bearing mode in prior art.
As shown in figure 1, the flow process includes：
Step 101, UE initiate data service application, to GPRS serving GPRS support nodes (SGSN) the application activation one of core net
Individual PDP Context.
Step 102, core net complete the foundation of PDP Context, and send RAB (Radio to wireless network
Access Bear, RAB) assignment messages, notify that wireless network sets up radio bearer for the data service, wherein in RAB assignment messages
Comprising QoS information.
The type of step 103, wireless network content and the ability rating information of UE, i.e. UE according to RAB assignment messages, is this
UE distributes interface-free resources.
In this step, the bearing mode that wireless network is adopted according to the type selecting of UE, specifically, if UE is the 4th version
(Release 4, R4) terminal, i.e. support R4 bearing modes, then be which distributes R4 resources, adopts R4 bearing modes, if UE
For HSDPA terminals, R4 bearing modes and HSDPA bearing modes is supported, then, in downlink data transmission, be its distribution HSDPA
Resource, i.e. adopt HSDPA bearing modes, if UE be HSUPA terminals, i.e. support R4 bearing modes, HSDPA bearing modes and
HSUPA bearing modes, then, in downlink data transmission, be its distribution HSDPA resource, i.e., using HSDPA bearing modes, up
During data transfer, it is its distribution HSUPA resource, adopts HSUPA bearing modes.
Wherein, the QoS information in RAB message includes that the traffic type information of the applied business of user is upper and lower with needs
Row data transmission rate information.The scheduling of resource work that traffic type information in QoS information is used for after business foundation by wireless network
Make, up-downgoing data transmission information is currently without being used by wireless network.
It can be seen that, prior art in order to improve the data traffic transmission speed of user, according to UE types for user data industry
Business selects bearing mode, as long as i.e. UE supports HSDPA or HSUPA bearing modes, be just user terminal selecting HSDPA or
HSUPA bearing modes.
However, the applicant is had found by the analysis to R4 bearing modes and HSPA bearing modes, R4 bearing modes and
HSPA bearing modes not only have difference in transfer rate, on the number of users that can in load-carrying efficiency, namely carry, and have
Difference, specifically refer to Fig. 2～Fig. 4.
Fig. 2 is the channel configuration figure of the R4 bearing modes under 2: 4 typical slot proportionings in TD-SCDMA system.
When using R4 bearing modes, the message transmission rate of user is in proportion with the physical channel resources of eating dishes without rice or wine for taking
It is corresponding.The DPCH resources of 2 code channels can carry the message transmission rate of 16kbps, and a time slot can carry 128kbps,
The maximum load-carrying capacity of one carrier wave is up 240kbps, descending 512kbps.And which carries number of users also with each user's
Message transmission rate is relevant, if the message transmission rate of each user is less than 16kbps, R4 single carriers can carry 15
User；And when the message transmission rate of each user is 32kbps, R4 single carriers can carry 7 users.
Fig. 3 is the channel configuration figure of the HSDPA bearing modes under 2: 4 typical slot proportionings in TD-SCDMA system.
During using HSDPA bearing modes, single carrier downlink transmission data rate is maximum up to 1.68Mbps, but carries and use
Amount is limited to DPCH channels.In due to Typical Disposition, descending adjoint DPCH channels only 6 dual tracks of residue, therefore it is single
The HSDPA numbers of users upper limit that carrier wave can be carried is 6, if introduced with channel frame point multiplexing, in 2 times of frames point multiplexing and
Under 4 times of frame point multiplexed situations, the number of users of carrying can be promoted to 12 and 24 respectively.
Fig. 4 is the channel configuration figure of the HSPA bearing modes under 2: 4 typical slot proportionings in TD-SCDMA system.
Wherein, HSPA bearing modes are introduced obtained from HSUPA bearing modes on the basis of HSDPA bearing modes.
When UE adopts HSPA bearing modes, single carrier downlink transmission data rate is maximum up to 1.68Mbps, and upstream rate is maximum
Up to 550kbps.Similarly, since being limited to DPCH channels, in the case where frame point multiplexing is not introduced, single carrier can be carried
HSPA numbers of users be 3 to the maximum, if introducing frame point multiplexing, under 2 times of frames point multiplexing and 4 times of frames point multiplexed situations, hold
Carry number of users and be respectively 6 and 12.
Identical situation is existed in WCDMA system.In a wcdma system, it is if adopting R4 bearing modes, single to carry
The ripple number of users that can carry of maximum up to 128, and if adopting HSDPA bearing modes, as descending HSDPA single carriers only have
16 code channels, it is contemplated that the expense of a control code channel, therefore single carrier is only capable of most 15 users of carrying.
Can be seen by analysis above, compared to R4 bearing modes, HSDPA bearing modes and HSUPA bearing modes
Although introducing can greatly lift the uplink and downlink message transmission rate of user, the number of users of each carriers carry also can
Being restricted, and in prior art, the bearing mode of data service being determined only according to UE types, this easily causes Radio Resource
The low problem of load-carrying efficiency.
The content of the invention
In view of this, the invention provides it is a kind of determine data service bearing mode method and apparatus, so as to ensure
While the message transmission rate of user, the load-carrying efficiency of Radio Resource is improved.
What technical scheme was specifically realized in：
A kind of method for determining data service bearing mode, the method include：
The message transmission rate of identifying user equipment (UE)；
When the bearing mode that UE is supported is two or more, the bearing mode that the message transmission rate of UE is supported with the UE
Scheduled rate threshold value be compared, according to comparative result determine UE adopt bearing mode.
A kind of device for determining data service bearing mode, the device include identification module and determining module；
The identification module, for the message transmission rate of identifying user equipment (UE)；
The determining module, for the bearing mode supported in UE for it is two or more when, by the message transmission rate of UE with
The scheduled rate threshold value of the bearing mode that the UE is supported is compared, and determines the bearing mode that UE is adopted according to comparative result.
As seen from the above technical solution, message transmission rate of the present invention by identification UE, in the bearing mode that UE is supported
For it is two or more when, the scheduled rate threshold value of the bearing mode that the message transmission rate of UE is supported with the UE is compared,
The bearing mode that UE is adopted is determined according to comparative result, compared with bearing mode being determined only according to UE types for UE, due to drawing
The message transmission rate of UE is entered, therefore has avoided and also distribute HSDPA bearing modes for the less UE of some message transmission rates
And/or HSUPA bearing modes, and then while the message transmission rate of user is ensured, improve the carrying effect of Radio Resource

Specific embodiment
The applicant by the message transmission rate to R4 bearing modes and HSDPA and/or HSUPA bearing modes and
The comprehensive analysis of load-carrying efficiency is learnt：When the message transmission rate of user is very big, using HSDPA and/or HSUPA bearing modes
It is well positioned to meet the demand of user；And when the message transmission rate of user is less, if held using HSDPA and/or HSUPA
Load mode, even if the user for then accessing reaches the access customer number upper limit, the data throughout summation of its accessing user also below
The data transmission capabilities of HSDPA carrier waves and/or HSUPA carrier waves, cause the waste of carrier resource, further, since HSDPA and
The load-carrying efficiency of HSUPA bearing modes is relatively low, if carrying excessive data transfer speed using HSDPA and/or HSUPA bearing modes
The less data service customers of rate, can also make really have the user of larger data transmission rate requirements access, and reduce user
Impression.
In order to avoid carrying the excessive less user of message transmission rate using HSDPA and/or HSUPA bearing modes,
Present applicant proposes a kind of method for selecting bearing mode according to the size of message transmission rate, specifically refers to Fig. 5.
Fig. 5 is that the present invention provides method flow diagram of the fixed number according to service bearer mode really.
As shown in figure 5, the method includes：
Step 501, the message transmission rate of identifying user equipment (UE).
Step 502, when the bearing mode that UE is supported is two or more, by the message transmission rate of UE and UE supports
The scheduled rate threshold value of bearing mode is compared, and determines the bearing mode that UE is adopted according to comparative result.
In method shown in Fig. 5, by recognizing the message transmission rate of UE, by the message transmission rate of UE and bearing mode
Scheduled rate threshold value is compared, it is possible to achieve select suitable bearing mode according to the message transmission rate of UE for UE, from
And avoid when the message transmission rate of UE is less, also HSDPA bearing modes and/or HSUPA bearing modes is selected for which, enter
And improve load-carrying efficiency.
In method shown in Fig. 5, QoS information can be read from RAB message, recognize the data transfer in the QoS information
Rate information, the initial time then set up in business, by the message transmission rate of UE, the bearing mode supported with the UE it is pre-
If rate threshold value is compared, the bearing mode for adopting is determined according to comparative result.
By determining the message transmission rate of UE according to the QoS information in RAB message, and then according to the message transmission rate
Select bearing mode so that UE just can adopt suitable bearing mode in the initial time that business is set up.
To enable with the change of UE message transmission rates, and the suitable bearing mode of real-time selection, the present invention
Also propose：During service bearer, RNC maintains data buffer to each UE, and calculates the data buffer of each UE
In data volume, according to the message transmission rate of the data volume calculating UE in a period of time in data buffer, and hold in business
During load, the UE message transmission rates that RNC is calculated, the scheduled rate threshold value of the bearing mode supported with the UE are carried out
Relatively, the bearing mode that UE should be adopted is determined according to comparative result, if it is determined that the bearing mode that the UE for going out should be adopted with
The bearing mode of the currently practical employings of UE is inconsistent, then the bearing mode of UE currently practical employing being changed to the UE should adopt
Bearing mode.
Wherein, scheduled rate threshold value of the present invention, according to the maximum data transfer rate identical in single carrier
Under the conditions of, the maximum relation carried between number of users under different bearer mode is obtained.
For example, can for every kind of bearing mode, draw under the bearing mode maximum data transfer rate of single carrier and
The bearing relation curve between number of users is carried, according to the bearing relation curve under different bearing modes, maximum data is selected
Under the conditions of transfer rate identical, the most bearing mode of number of users is carried, i.e., when the abscissa of the bearing relation curve is
Maximum data transfer rate, ordinate select carrying number of users corresponding in upper relation curve for carrying during number of users, all the time
Bearing mode.
Therefore, the scheduled rate threshold value in the bearing mode for being supported the message transmission rate of UE with the UE is compared
Compared with when determining the bearing mode that UE is adopted according to comparative result, by the maximum data transfer rate identical condition in single carrier
Under, it is maximum in various bearing modes to carry the most bearing mode of number of users, it is defined as the bearing mode that the UE is adopted.
At present, the bearing mode that UE is supported generally comprises R4 bearing modes, HSDPA bearing modes and HSUPA bearing modes,
As HSDPA bearing modes and HSUPA bearing modes can provide higher message transmission rate, but load-carrying efficiency is relatively low, and
R4 can improve higher load-carrying efficiency, but the message transmission rate that can be provided is relatively low, therefore when the loading side of UE supports
When formula includes R4 bearing modes and HSDPA bearing modes and/or HSUPA bearing modes, the present invention is proposed, according to comparing knot
Fruit determines that the bearing mode that UE is adopted includes：When the message transmission rate of UE is less than scheduled rate threshold value, the UE adopts R4
Bearing mode, UE message transmission rate be more than scheduled rate threshold value when, the UE adopt HSDPA bearing modes and/or
HSUPA bearing modes.
Further, if UE supports HSDPA bearing modes and/or HSUPA bearing modes, whether UE is open-minded
The frame of HSDPA bearing modes and/or HSUPA bearing modes point multiplexing function, influences whether HSDPA bearing modes and/or HSUPA
Message transmission rate and load-carrying efficiency that bearing mode is provided, and then the concrete value of rate threshold value is influenced whether, therefore, this
Invention is proposed：
If UE does not open the frame point multiplexing function of HSDPA bearing modes and/or HSUPA bearing modes, UE's
When message transmission rate is less than the first scheduled rate threshold value, the UE adopts R4 bearing modes, big in the message transmission rate of UE
When the first scheduled rate threshold value, the UE adopts HSDPA bearing modes and/or HSUPA bearing modes；If UE is open-minded
2 times of frames of HSDPA bearing modes and/or HSUPA bearing modes point are multiplexed function, then the message transmission rate in UE is less than second
During scheduled rate threshold value, the UE adopts R4 bearing modes, is more than the second scheduled rate threshold value in the message transmission rate of UE
When, the UE adopts HSDPA bearing modes and/or HSUPA bearing modes.
Further, the applicant is carried to R4 bearing modes, HSDPA bearing modes and HSUPA in TD-SCDMA system
Relation between message transmission rate that mode can be provided and load-carrying efficiency has carried out detailed comparative analysis, and then determines
For determining the concrete value of the rate threshold value of bearing mode, 1～table of table 2 and Fig. 6～Fig. 7 is specifically referred to.Wherein, carry
The load-carrying efficiency of mode is referred to, when carrying the data service of typical rate using the bearing mode, the list of the bearing mode

According to table 1, the pass between average downlink transmission data rate and the number of users under different bearer mode can be obtained
It is comparison diagram, specifically refers to Fig. 6.
Fig. 6 is between average downlink transmission data rate and number of users in TD-SCDMA system under different bearer mode
Relation comparison diagram.
Can be intuitive to see from Fig. 6, when HSDPA bearing modes do not adopt frame division multiplexing technology, carry
During the business of 64kbps and its following speed, using the bearing mode of R4, which carries number of users and is all more than using HSDPA loading sides

During the business of rate, using the bearing mode of R4, which carries number of users and is all more than using carrying user during HSDPA bearing modes
Number；When HSDPA bearing modes adopt 4 times of frame division multiplexing technologies, then can be obtained using HSDPA bearing modes under any circumstance
Obtain maximum load-carrying efficiency.It is it is contemplated that higher frame point multiplexing multiple can have a strong impact on the link-quality of user, therefore existing
It is more difficult in net to take 4 times of frame division multiplexing technologies.

When mode adopts 4 times of frame division multiplexing technologies, when the business of 16kbps and its following speed is carried, using R4 bearing modes, its
Carry number of users to be all more than using carrying number of users during HSUPA bearing modes.It is contemplated that higher frame point multiplexing multiple
The link-quality of user can be had a strong impact on, therefore more difficult in existing network takes 4 times of frame division multiplexing technologies.
Can be seen by the analysis of Fig. 6-Fig. 7 different bearer mode load-carrying efficiencies, although HSDPA bearing modes and
HSUPA bearing modes can provide higher message transmission rate, it is contemplated that the number of users that single carrier is carried is limited, if held
The business for carrying user is the less business of message transmission rate, then using HSDPA bearing modes and/or HSUPA bearing modes
The waste of bearing capacity can be caused.Bearing mode should be adjusted in real time according to the actual data transfer rate of user：Work as data
When transfer rate is larger, using HSDPA bearing modes and/or HSUPA bearing modes；When message transmission rate is less, adopt
R4 bearing modes.Wherein, according to Fig. 6～Fig. 7, in TD-SCDMA system, for determining the rate threshold value bag of bearing mode
First rate threshold value and the second rate threshold value is included, first rate threshold value, for not opening HSDPA bearing modes in UE
And/or 2 times of frames of HSUPA bearing modes point determine the bearing mode that UE should be adopted, the first rate thresholding when being multiplexed function
The concrete value of value is 64kbps, and the second rate threshold value, for having opened HSDPA bearing modes and/or HSUPA carryings in UE
The bearing mode that UE should be adopted is determined during 2 times of frames of mode point multiplexing function, and the concrete value of the second rate threshold value is
32kbps。
Fig. 8 is the method flow diagram of the bearing mode for determining that UE should be adopted in TD-SCDMA system.
As shown in figure 8, the method includes：
Step 801, UE initiate data service application, to SGSN application one PDP Context of activation of core net, wherein wrap
Include QoS information.
Step 802, core net complete the foundation of PDP Context, and send RAB assignment messages to wireless network, notify wireless
Net sets up radio bearer for the data service, the QoS information comprising business in the RAB assignment messages.Wherein, the QoS information
Include the message transmission rate information of data service.
Step 803, wireless network RNC are its selection loading side according to the QoS information in the business RAB assignment messages
Formula.
In this step, if UE support bearing mode include R4 bearing modes and HSDPA bearing modes and/or
HSUPA bearing modes, if then HSDPA carrier waves and/or HSUPA carrier waves are not turned on frame point multiplexing function, then in QoS information
In up and/or downlink service data transmission rate information be less than 64kbps when, be defined as the data service using R4 carrying
Mode, when the up and/or downlink service data transmission rate information in QoS information is more than 64kbps, is defined as the data
Business adopts HSDPA bearing modes and/or HSUPA bearing modes；If HSDPA carrier waves and/or HSUPA carrier waves open 2 times
Frame point multiplexing function, then when the up and/or downlink service data transmission rate information in QoS information is less than 32kbps,
It is defined as the data service using R4 bearing modes, the up and/or downlink service data transmission rate information in QoS information
During more than 32kbps, it is defined as the data service using HSDPA bearing modes and/or HSUPA bearing modes.

Step 805, RNC are by the message transmission rate obtained to each service computation and are used for determining the speed of bearing mode
Threshold value is compared, according to the suitable bearing mode of selection of message transmission rate.Specifically：
When user it is currently employed when being HSDPA bearing modes and/or HSUPA bearing modes, if it is multiple not open frame point
With function, then when message transmission rate drops to 64kbps or following, while delay speed when waiting certain sluggish still existing
Below 64kbps, it should be adjusted to R4 bearing modes.
When user it is currently employed when being HSDPA bearing modes and/or HSUPA bearing modes, if it is multiple to open 2 times of frames point
With function, then when message transmission rate drops to 32kbps or following, while delay speed when waiting certain sluggish still existing
Below 32kbps, it should be adjusted to R4 bearing modes.
When user it is currently employed when being R4 bearing modes, if not opening HSPA frames point multiplexing function, when data biography
When defeated speed is more than 64kbps, while delaying speed still in more than 64kbps when waiting certain sluggish, it should be adjusted to
HSDPA bearing modes and/or HSUPA bearing modes.
When user it is currently employed when being R4 bearing modes, if open HSDPA bearing modes and/or HSUPA carried
2 times of frames of mode point multiplexing function, then when message transmission rate is more than 32kbps, while delay speed when waiting certain sluggish
Still in more than 32kbps, it should be adjusted to HSDPA bearing modes and/or HSUPA bearing modes.
The method of bearing mode that UE should be adopted is determined in a wcdma system, and the difference with method shown in Fig. 8 is,
Rate threshold value for determining bearing mode is different.
In a wcdma system, if adopt HSDPA and/or HSUPA bearing modes, single carrier maximum carry simultaneously
15 users, the average descending maximum data transfer rate of each user is 960kbps.And when adopting R4 bearing modes, still
15 users are carried, the downlink transmission data rate of each user is 128kbps.Although under R4 bearing modes, user data is passed
Defeated speed speed is less than HSDPA bearing modes and HSUPA bearing modes, but under R4 bearing modes, single carrier can be connect simultaneously
The maximum number of user for entering is higher than HSDPA bearing modes and HSUPA bearing modes.When user data transmission speed is less than 128kbps
When, the access demand more than 15 users can be met using R4 bearing modes.Therefore, for WCDMA system, it is only necessary to by Fig. 8
Rate threshold value 128kbps is adjusted to by 64kbps, i.e.,：
When user data transmission speed is less than or equal to 128kbps, RNC is adjusted to R4 bearing modes；Work as user
When message transmission rate is higher than 128kbps, RNC is adjusted to HSDPA bearing modes and/or HSUPA bearing modes.

It is with conditions of, maximum in various bearing modes to carry the most bearing mode of number of users, it is defined as the loading side that the UE is adopted
Formula；Wherein, the scheduled rate threshold value, according under the conditions of the maximum data transfer rate identical of single carrier, difference is held
The maximum relation carried between number of users under load mode is obtained.
If the bearing mode that UE is supported includes R4 bearing modes and HSDPA bearing modes and/or HSUPA loading sides
