Description
Technical field
The present invention relates to communication technical field, particularly to the Radio Resource distribution side of a kind of multicarrier system
Method.The present invention also relates to the radio resource allocation module of a kind of multicarrier system.
Background technology
TD-SCDMA(Time Division-Synchronous Code Division Multiple Access,
TD SDMA) network there are HSPDA(High Speed Downlink Packet
Access, high-speed down data accesses) carrier wave and R4(Release4 version) carrier wave, wherein HSDPA
The interference of carrier wave is big relative to R4 carrier wave, so signaling can be bigger in the success rate that R4 carrier wave accesses.Existing
The resource allocation policy that signaling accesses is assisted for RRC(Radio Resource Control, wireless heterogeneous networks
View) reason of setting up do not make a distinction, the most any signaling setting up reason all can preferentially be entered at R4 carrier wave
Row accesses, if R4 carrier resource deficiency will directly attempt accessing at HSDPA carrier wave.
But in a practical situation, R4 resource is the most all limited, the most preferential in all types of signalings
On the premise of selecting R4 carrier wave to access, it is impossible to ensure that voice signaling can be linked into R4 carrier wave, this
Sample can affect the percent of call completed of speech business, affects voice user's perception, and specifically, it will cause following
The appearance of situation:
(1) according to existing network statistical data, it is voice letter that the RRC of non-voice signaling sets up data
Make RRC set up 5～10 times of data, when a large amount of non-voice signalings access at R4 carrier wave, R4 can be caused to carry
Ripple is congested, and voice signaling is congested and only have access at HSDPA carrier wave due to R4 carrier wave.
(2), after R4 carrier wave access failure, can attempt accessing at HSDPA carrier wave.And in H carrier-in-interference
In the case of great, it will occur that " if uplink interference is big when signaling accesses, the RRC of terminal has set up and disappeared
Breath RNC may can not receive ", " if descending interference is big when signaling accesses, terminal may can not receive RRC and build
Vertical message ", " it is big that speech business accesses descending interference, owing to signaling is at HSDPA carrier wave, so eating dishes without rice or wine
Radio Bearer Setup set up message, terminal may can not receive " etc. hidden danger.
As can be seen here, existing RRC radio resource allocation strategy cannot set up cause type according to RRC
Make a distinction, it is impossible to ensure that important signaling preferentially can disturb less carrier wave to access, thus
Cause important signaling to set up and disturbing bigger carrier wave, important signaling and business are created as power and make
Become impact, reduce the perception of user.
Summary of the invention
Do not differentiate between type of service during for solving carrier resource distribution in prior art and cause speech business to be connected
The problem that rate is low, the present invention proposes the wireless resource allocation methods of a kind of multicarrier system, including:

Detailed description of the invention
Reason cannot be set up according to RRC for multicarrier system in solution prior art and carry out resources configuration optimization
Technical problem, as it is shown in figure 1, the present invention proposes a kind of wireless resource allocation methods, including following
Step:
S101, receives RRC connection request message.
It should be noted that before receiving RRC connection request message, in addition it is also necessary to set up former for RRC
Because type arranges the radio resource allocation strategy of correspondence.Specifically, RRC is set up cause type by the present invention
At least be divided into voice and set up reason and non-voice sets up the big class of reason two, and based on R4 carrier wave and
The HSDPA carrier wave following radio resource allocation strategy of formulation:
Arranging described voice and setting up the radio resource allocation strategy of reason is priority access carrier policies or the most fair
Permitted access carrier strategy, described priority access carrier policies or be allows only access the load specified by carrier policies
Ripple is R4 carrier wave；
Arranging non-voice and setting up the radio resource allocation strategy of reason is excellent priority access carrier policies or the most fair
Permitted access carrier strategy, described priority access carrier policies or be allows only access the load specified by carrier policies
Ripple is HSDPA carrier wave.
S102, sets up reason according to the RRC in described RRC connection request message, determines that RRC sets up
Cause type.
S103, sets up, based on described RRC, the radio resource allocation strategy that cause type is corresponding, for institute
State signaling corresponding to connection request message and select access carrier, to realize the load to described RRC connection request
Wavelength-division is joined.
In S101, radio resource allocation strategy is divided into priority access carrier policies and has only allowed to connect
Entering carrier policies two kinds, specifically each different allocation strategy all has different processing modes:
When described radio resource allocation strategy is priority access carrier policies, to described priority access carrier wave
The carrier wave that strategy is specified accesses, if described carrier wave cannot be accessed, then selects other carrier waves to access.
When described radio resource allocation strategy is for being allows only access carrier policies, only described only permission is connect
Enter the carrier wave that carrier policies specifies to access.
It should be noted that during described carrier wave is accessed, first described carrier wave is carried out
Signal resource distribution is attempted；If resource distribution is attempted unsuccessfully, then account for enterprising the robbing of described carrier wave, if robbing
If accounting for failure, then confirm that described carrier wave cannot access.Correspondingly, finally own when both the above situation
Carrier wave when all cannot access, then return RRC refusal response, to be redirected to GSM(Global System
For Mobile Communications, global system for mobile communications).
In order to the technological thought of the present invention is expanded on further, in conjunction with concrete application scenarios, to the present invention
Technical scheme illustrate.As in figure 2 it is shown, the Radio Resource for specific embodiment of the invention proposition divides
Method of completing the square, comprises the steps:

And set up reason for difference and the carrier type of priority access be set: such as voice set up reason, permissible
It is configured to preferentially/is only allowed in R4 carrier wave by OAM access, then access in signaling for such reason
Time, the radio resource allocation strategy of network side can preferential/be only allowed in R4 carrier wave and carry out access attempts；Right
Reason is set up in intersystem reselection etc., can be configured to preferentially by OAM/it is only allowed in HSDPA carrier wave
Access, then for such reason when signaling accesses, the radio resource allocation strategy of network side can preferential/
It is only allowed in HSDPA carrier wave and carries out access attempts.So can ensure high preferential from the angle of MRP
The probability that the RRC connection request message (such as voice) of level is successfully accessed at R4 carrier wave.
S202, carries out carrier wave Access Control according to radio resource allocation strategy.
As it is shown on figure 3, be this specific embodiment concrete carrier wave in step S201 two kinds of Different Strategies

Slightly, illustrate: when setting up reason and being set to preferentially access at R4 carrier wave, network side for such
Set up reason first round when Radio Resource distributes only to attempt accessing at R4 carrier wave, if access failure, the most directly
It is connected on enterprising the robbing of R4 carrier wave and accounts for (such as seizing PS business reduction of speed, release)；If it is the most failed, then
Network can attempt the second resource allocation policy taken turns, and is can to attempt connecing at HSDPA carrier wave in taking turns second
Enter.
2) certain class RRC is set up reason and is set to be only allowed in resource allocation policy when certain carrier wave accesses,
Illustrate: when setting up reason and being set to only access at R4 carrier wave, network side is set up former for such
Because only carrying out taking turns resource distribution trial when resource is distributed, i.e. it is only allowed in R4 carrier wave and accesses, if resource
Distribute and the most only carry out seizing (such as seizing PS business reduction of speed, release) at R4 carrier wave, if failure,
Terminate, will not attempt accessing at HSDPA carrier wave.
