A method for configuring transmission format of adaptive multirate voice includes configuring uplink and downlink AMR voice rate supported currently and configuring transmission format corresponding to AMR voice at Uu interface by RNC according to current channel ability and AMR voice rate assigned by RAB message sent by CN when AMR voice service is set up, then decreasing AMR voice transmission format supported currently by RNC when UE transmission ability is limited and increasing AMR voice transmission format supported current by RNC when UE transmission ability is raised.
Description
Technical field
The present invention relates to the adaptive multi-rate speech transmission field, be specifically related to a kind of adaptive multi-rate speech transmitting format configurating method.
Background technology
At present, in order to save the transmission band resource, keep high efficiency voice communication simultaneously, Wideband Code Division Multiple Access (WCDMA) (WCDMA, Wideband Code Division Multiple Address) system has adopted based on algebraic codebook Excited Linear Prediction (ACELP, Algebraic Code Excited Linear Prediction) adaptive multi-rate (AMR, the Adaptive Multi-Rate) speech coding technology of principle.The principle of ACELP is: owing to the characteristic information in the audio digital signals not only comprises some speech characteristic parameters but also comprises the portion waveshape coded message, use these characteristic informations synthetic speech signal again.And control the extraction number of these characteristic informations, require respectively characteristic information to be accepted or rejected just to obtain multiple AMR voice rate according to voice rate.In the voice transfer process, user terminal (UE, User Equipment) can be realized the voice transfer of different phonetic speed by selecting different speech transmitting formats when changing voice rate.
Fig. 1 is the schematic diagram that prior art is set up the AMR speech business, and as shown in Figure 1, its concrete steps are as follows:
Step 101: core net (CN, Core Network) is by all AMR voice rates of RAB (RAB, RadioAccess Bearer) message informing radio network controller (RNC, Radio Network Controller);
After step 102:RNC receives,, in the speed of RAB message assignment, select the actual AMR voice rate of supporting according to the transmission channel ability of current UE;
It is to be noted, RNC also will initiate Iu User Plane agreement (IUUP to CN after receiving RAB message, Iu User Plate Protocol) initialization procedure, promptly send the initialization control frame to CN, after receiving, CN returns initialization control acknowledgement frame to RNC, simultaneously, the maximum AMR voice rate that first AMR voice rate that carries in the RNC appointment initialization control frame is supported as reality, the AMR voice rate of the actual support that RNC determines at last must be less than or equal to this maximum AMR voice rate.IUUP initialization and RNC dispose the actual AMR voice rate process of supporting, there is no the branch of strict priority, and still, these two processes are that RNC must carry out after receiving RAB message.
Step 103:RNC after UE receives, self is disposing this AMR speech transmitting format at Uu interface configuration and the complete corresponding AMR speech transmitting format of the actual AMR voice rate of supporting.
In the prior art, in a single day the AMR voice rate is configured, and just can't reconfigure, unless initiate the IUUP initialization procedure again.But, because the AMR speech business is set up, therefore can not initiate the IUUP initialization procedure again, will produce following problem like this:
RNC has disposed the AMR voice rate of actual support as much as possible when one, setting up as if the AMR speech business, and the Uu interface will dispose the AMR speech transmitting format of similar number, thereby will take the more transmission channel resources of UE.Like this, when the new business that will set up again beyond the AMR speech business,, so just may cause the new business access failure because of the transmission channel limited ability of UE because the number of AMR speech transmitting format can't reduce;
RNC has disposed the AMR voice rate of less actual support when two, setting up as if the AMR speech business, and so, the Uu interface will dispose same fewer purpose AMR speech transmitting format.Though other business beyond the AMR speech business that can guarantee so successfully inserts, but when the business beyond the AMR speech business discharges, still exist under the situation of AMR speech business, because the number of AMR speech transmitting format can't increase, therefore, will cause under the condition that the transmission channel ability of UE allows, also can't use more AMR voice rate transferring voice.

Embodiment
Fig. 2 is an AMR speech transmitting format configuration schematic diagram provided by the invention, as shown in Figure 2, when setting up the AMR speech business, the AMR voice rate of the RAB message assignment that RNC sends according to the transmission channel ability of current UE and CN, dispose the uplink and downlink AMR voice rate of current support, the while is at the AMR speech transmitting format of Uu interface configuration correspondence.Afterwards, when RNC detects the transmission channel limited ability of current UE, just reduce the number of the AMR voice rate of current support, and behind the AMR speech transmitting format of corresponding modification Uu interface, the AMR speech transmitting format is sent to UE; When RNC detects the transmission channel ability raising of current UE, just increase the number of the AMR voice rate of current support, and behind the AMR speech transmitting format of corresponding modification Uu interface, the AMR speech transmitting format is sent to UE.
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
At first, when setting up the AMR speech business, receive the RAB message of CN transmission as RNC after, preserve all AMR voice rates of assignment in the RAB message, initiate the IUUP initialization procedure then, and according to the uplink and downlink transmission channel ability of UE, the actual uplink and downlink AMR voice rate of supporting of configuration, and according to the uplink and downlink AMR voice rate of actual support the Uu interface dispose respectively corresponding on, row AMR speech transmitting format.
The universal class P of the AMR voice rate of RAB message assignment can be expressed as:
P＝{R1，R2，...，Rn，DTX_SID，DTX_NoData} (1)
Wherein, R1 ..., Rn is the AMR voice rate of non-discontinuous transmission (DTX, Discontinuous Transmission) speed, and DTX_SID is the data frame transfer speed of mourning in silence, and DTX_NoData is zero transmission rate.
Can specify R1 is flank speed, is beneficial to rate controlled.
RNC is when the uplink and downlink AMR voice rate of the current support of configuration, and its foundation is different, and is specific as follows:
One, RNC must satisfy minimum up AMR voice rate principle when collocating uplink AMR voice rate.
Minimum up AMR voice rate principle is that up AMR voice rate must comprise three kinds of speed at least, and they are respectively: a kind of non-DTX speed that guarantees speed and be not higher than the maximum AMR voice rate of RNC appointment, two kinds of DTX speed of being not less than.
The maximum AMR voice rate of RNC appointment, promptly RNC sends to first AMR voice rate that carries in the initialization control frame of CN when initiating the IUUP initialization procedure.
Usually, the uplink transport channel of UE energy force rate descending transmission channel ability is little, therefore easier to be limited.For the AMR voice, the non-DTX speed of other except DTX speed can transmit the voice signal of compression, therefore can only select the wherein a kind of non-DTX speed of RAB message assignment to carry out the compression and the transmission of voice.As can be seen, than the AMR voice (AMR-NB that comprises 10 kinds of speed, AMR Narrowband) full configuration mode of speed and the wideband A MR voice (AMR-WB that comprises 11 kinds of speed, AMR Wideband) the full configuration mode of speed, use this minimum transformat configuration mode configuration AMR speech transmitting format decreased number 2/3.
Uplink transport channel ability according to minimum up AMR voice rate principle and UE, RNC selects two DTX speed promptly in the voice rate of RAB message assignment: DTX_SID, DTX_NoData and at least one are not less than the non-DTX speed that guarantees speed and be not higher than the maximum AMR voice rate of RNC appointment, as up AMR voice rate.
If the transmission channel ability allows, up AMR voice rate set can be defined as identical with the AMR voice rate set P of RAB message assignment.
The minimal set M of up AMR voice rate can be expressed as:
M={ Rm, DTX_SID, DTX_NoData}, 1≤m≤n, the maximum AMR voice rate 〉=Rm of RNC appointment 〉=assurance speed (2)
Wherein, n is identical with n in the formula (1).
The general set Q of up AMR voice rate can be expressed as:
Q={Ri ..., Rj, DTX_SID, DTX_NoData}, 1≤i, j≤n, the maximum AMR voice rate 〉=Ri of RNC appointment ..., Rj 〉=assurance speed (3)
M, Q are the subclass of P, n is identical with n in the formula (1), guarantee that speed carries for RAB message.
Two, RNC uses the maximum rate control principle when configurating downlink AMR voice rate.
The maximum rate control principle, be that RNC selects one and is not less than assurance speed in the non-DTX speed of RAB message assignment, and the non-DTX speed that is not higher than the maximum AMR voice rate of RNC appointment, this speed and all are lower than other the non-DTX speed and the DTX speed of this speed and form descending AMR voice rate, and the transformat of these speed correspondences is descending AMR speech transmitting format.
The S set of descending AMR voice rate can be expressed as:
S={Ri, Ri+1 ..., Rn-1, Rn, DTX_SID, DTX_NoData}, i 〉=1, the maximum AMR voice rate 〉=Ri of RNC appointment 〉=assurance speed (4)
S is the subclass of P.Here, establish the voice rate of set among the P by descending, promptly R1＞R2＞...＞Rn-1＞Rn.
It is pointed out that when setting up the AMR speech business, under the situation that the transmission channel ability of UE allows, when RNC disposes the uplink and downlink AMR voice rate of current support, also can be same as the prior art.
When combinations of services changed, RNC need reconfigure the professional transformat of uplink and downlink, improves according to UE transmission channel limited ability and transmission channel ability, is divided into two kinds of situations:
One, under the situation of UE transmission channel limited ability:
(1) UE uplink transport channel limited ability.Be divided into two kinds of situations according to setting up the AMR speech business and will setting up the AMR speech business:
A, set up when the AMR speech business, set up beyond the AMR speech business other again when professional, RNC detects the uplink transport channel limited ability of UE, as shown in Figure 3, carries out reconfiguring of up AMR speech transmitting format according to following steps:
301: under the situation of setting up the AMR speech business, CN sends to RNC and sets up other service request;
302:RNC detects the uplink transport channel limited ability of current UE;
RNC receive CN set up the request of other business the time, can at first obtain the transmission channel ability of current UE to UE or other RNC etc., then according to the particular type of this service request, estimate to set up the transmission channel resources that this business need take, and judge whether the remaining transmission channel resources of UE is enough to set up this business, if begin to set up this business; Otherwise, just think the transmission channel limited ability of current UE.
303:RNC is reduced to the non-DTX speed in the up AMR voice rate of current support at least a according to remaining uplink transport channel resource of current UE and the transmission channel resources of setting up other service needed;
The up AMR voice rate of current support must satisfy minimum up AMR voice rate principle.
304:RNC sets up the up AMR speech transmitting format of amended up AMR voice rate correspondence (RB Setup) message by radio bearer and sends to UE;
RB Setup message is carried other newly-built professional transformat simultaneously.
305:UE receives this message, according to the transformat that this message is carried, finishes reshuffling of up AMR speech transmitting format, returns RB Setup to RNC then and finishes (RB SetupComplete) message.
B, other business beyond the AMR speech business are set up, and when setting up the AMR speech business again, RNC detects the uplink transport channel limited ability of UE, as shown in Figure 4, carries out the configuration of up AMR speech transmitting format according to following steps:
401: setting up under other professional situation, CN sends RAB message to RNC;
The assignment of RAB message the AMR voice rate.
402:RNC detects the uplink transport channel limited ability of current UE;
403:RNC disposes the up AMR voice rate of current support according to the speed of the RAB message assignment of remaining uplink transport channel resource of current UE and CN transmission, and formula (3) is seen in this speed set;
The up AMR voice rate of current support must satisfy minimum up AMR voice rate principle.
The up AMR speech transmitting format of the up AMR voice rate correspondence that 404:RNC will dispose is set up (RB Setup) message by radio bearer and is sent to UE;
405:UE receives this message, according to the transformat that this message is carried, finishes the configuration of up AMR speech transmitting format, returns RB Setup to RNC then and finishes (RB Setup Complete) message.
(2) UE descending transmission channel limited ability.Be divided into two kinds of situations according to setting up the AMR speech business and will setting up the AMR speech business:
