Background technology
The HSDPA technology is a kind of technology of carrying out high speed data transfer on the down link of WCDMA system.The HSDPA technology adopts mixes the short frame technique of automatic retransmission technique, Adaptive Modulation and Coding technology and descending 2ms, can realize eating dishes without rice or wine peak rate up to 13.976Mbps, therefore, can greatly improve the throughput of down user data, improve the downlink capacity of WCDMA system.
When adopting the HSDPA technology, the downlink data in the WCDMA system can be carried on the high speed descending sharing channel (HS-DSCH) and transfer to portable terminal.To be prior art be carried on the HS-DSCH and adopt the flow chart of affirmation mode transmitting downlink data at the downlink data of WCDMA system Fig. 1.Referring to Fig. 1, in the prior art, the downlink data of WCDMA system is carried on the HS-DSCH, and adopts the process that affirmation mode transmits may further comprise the steps:
Step 101: the MAC-DATA request primitive that Radio Link in the radio network controller (RNC) control (RLC) entity will carry self downlink data is sent to the MAC-d entity among the RNC.
Here, described MAC-DATA request primitive by agreement set, employed order during MAC-d inter-entity transmission downlink data in RNC among RLC entity and the RNC.
In addition, in this step, entrained downlink data can comprise two types protocol Data Unit (PDU) in the MAC-DATA request primitive, i.e. data PDU and control PDU.Wherein, data PDU comprises two types of New Development data PDU and data retransmission PDU again.
Step 102:MAC-d entity obtains downlink data from the MAC-DATA request primitive that receives, and determines the dispatching priority of this downlink data.
Here, the MAC-d entity can such as being the mapping relations shown in the table 1, be determined the dispatching priority of downlink data according to the mapping relations between pre-configured type of service, Business Processing priority and the dispatching priority.Wherein, Business Processing priority is that 1 priority is the highest, and the rest may be inferred, and Business Processing priority is that 15 priority is minimum; Dispatching priority is that 14 priority is the highest, and the rest may be inferred, and dispatching priority is that 0 priority is minimum.

Table 1
Referring to table 1, such as, the data that receive of MAC-d entity are the interaction service type in this step, and its corresponding service processing priority is 3, and then the MAC-d entity can determine that the dispatching priority of the downlink data that obtained is 12.
All downlink datas that the utilization of step 103:MAC-d entity is obtained generate a HS-DSCH Frame, and determined dispatching priority information is carried at the MAC-hs entity that sends in this HS-DSCH Frame in basic upright the accounting for.
After step 104:MAC-hs entity receives the HS-DSCH Frame, according to the dispatching priority information of wherein carrying all data of this HS-DSCH Frame are distributed in the formation of a respective priority of corresponding current receiver.
Here, the corresponding different recipient of each formation of MAC-hs entity inside, and all formations of corresponding same recipient have different dispatching priority ranks, therefore, in this step, the MAC-hs entity is distributed to this HS-DSCH Frame in the formation with corresponding dispatching priority of corresponding current receiver according to the dispatching priority information of carrying in the HS-DSCH Frame.
Step 105: when the formation of this corresponding dispatching priority of the corresponding current receiver of scheduling, the MAC-hs entity is sent to terminal (UE) according to the principle of first in first out with all data in this formation.
By above description as can be seen, in the prior art, generally include dissimilar PDU in the downlink data of RLC entity, be New Development data PDU, data retransmission PDU and control PDU, and the RLC entity is to MAC-d entity transmission downlink data the time, in the MAC-DATA request primitive, do not distinguish New Development data PDU, data retransmission PDU and control PDU, thereby make the MAC-d entity utilize New Development data PDU, data retransmission PDU and control PDU combination to generate a HS-DSCH Frame.Because the MAC-d entity is determined a dispatching priority for the HS-DSCH Frame of institute's combination generation, thus make in the HS-DSCH Frame New Development data PDU, data retransmission PDU and control PDU and have identical dispatching priority.Afterwards, the MAC-hs entity in the base station then directly according to determined same priority, is kept at the New Development data PDU in the HS-DSCH Frame, data retransmission PDU and control PDU in the same formation when receiving the HS-DSCH Frame.Like this, owing in a formation, must follow the principle of first in first out, when in the formation when there are a lot of New Development data PDU before the PDU in data retransmission PDU and control, data retransmission PDU in the formation and control PDU must wait until then that New Development data PDU before all is sent out away and just can be scheduled later on and send to UE.
In such cases, if UE is in the relatively poor wireless environment of channel condition, MAC-hs entity in the base station then can be very little to the speed of UE transmission data, so then can cause controlling PDU and wait for that in formation long time just can be scheduled and sends to UE, therefore also just makes UE wait for that long time just can receive control PDU.Owing to having carried state report information among the control PDU, when UE did not receive control PDU for a long time, meeting active disconnection was connected with network side, thereby causes the UE call drop.Simultaneously, because before data retransmission PDU is not sent out away in formation, this data retransmission PDU can take the transmission resource of RLC entity all the time, so if data retransmission PDU waits for long time in formation, can make that then the send window of RLC entity for a long time can't be to front slide, thereby influence downlink transmission data rate greatly.
This shows that any one among control PDU or the data retransmission PDU can't in time be sent out away, all can cause the downlink transfer degradation, thereby reduce user's satisfaction.

In table 2, Business Processing priority is that 1 priority is the highest, and the rest may be inferred, and Business Processing priority is that 15 priority is minimum; Dispatching priority is that 15 priority is the highest, and the rest may be inferred, and dispatching priority is that 0 priority is minimum.
Step 202: in the MAC-DATA request primitive, increase a type bit that is used to indicate the PDU type in advance, and control PDU, data retransmission PDU and New Development data PDU difference corresponding first kind offset, second types value and the 3rd types value are set.
Here, in the MAC-DATA request primitive, increase a type bit that is used to indicate the PDU type, and New Development data PDU, data retransmission PDU and the corresponding respectively inhomogeneity offset of control PDU are set, and are in order to make the MAC-d entity distinguish dissimilar PDU according to the types value on the type bit in the MAC-DATA request primitive in subsequent process.
Step 203: when sending downlink data, RLC entity among the RNC uses 3 MAC-DATA request primitives, on the type bit of MAC-DATA request primitive 1, write first kind offset, and will control PDU and be carried in the MAC-DATA request primitive 1, and, on the type bit of MAC-DATA request primitive 2, write second types value, and data retransmission PDU is carried in the MAC-DATA request primitive 2, and, on the type bit of MAC-DATA request primitive 3, write the 3rd types value, and the New Development data PDU is carried in the MAC-DATA request primitive 3.
Each MAC-DATA request primitive that RLC entity among the step 204:RNC will carry New Development data PDU, data retransmission PDU and control PDU is sent to the MAC-d entity among the RNC.
MAC-d entity among the step 205:RNC obtains control PDU, data retransmission PDU and the New Development data PDU of carrying in each MAC-DATA request primitive respectively after receiving each MAC-DATA request primitive that the RLC entity sends according to the types value on the type bit in each MAC-DATA request primitive.
Here, owing to be first kind offset on the type bit in the MAC-DATA request primitive 1, such as being 01, it in the MAC-DATA request primitive 2 second types value, such as being 10, it in the MAC-DATA request primitive 3 the 3rd types value, such as being 11, owing to set in advance control PDU, data retransmission PDU and New Development data PDU be corresponding first kind offset respectively, second types value and the 3rd types value, so, MAC-d entity among the RNC then can obtain control PDU from MAC-DATA request primitive 1, obtain data retransmission PDU from MAC-DATA request primitive 2, obtains the New Development data PDU from MAC-DATA request primitive 3.
MAC-d entity among the step 206:RNC is determined the dispatching priority of the current New Development data PDU of obtaining, data retransmission PDU and control PDU according to the dispatching priority of the New Development data PDU that sets in advance, data retransmission PDU and control PDU.
Here, MAC-d entity among the RNC is defined as the dispatching priority of the data retransmission PDU that obtained and control PDU time high and the highest, and determines the dispatching priority of this New Development data PDU according to the type of service of the New Development data PDU of being obtained and the RLC entity corresponding service processing priority of sending this New Development data PDU.
Such as, control PDU, the data retransmission PDU that MAC-d entity among the RNC obtains respectively from the MAC-DATA request primitive 1, MAC-DATA request primitive 2 and the MAC-DATA request primitive 3 that receive and the type of service of New Development data PDU are interaction service, and the RLC entity corresponding service processing priority of sending this New Development data PDU is 5, then according to above-mentioned table 2, the dispatching priority that can determine the current New Development data PDU of obtaining is 10, the dispatching priority of the current data retransmission PDU that obtains is 14, and the dispatching priority of the current control PDU that obtains is 15.
Control PDU, data retransmission PDU and New Development data PDU that the utilization of step 207:MAC-d entity is obtained generate a HS-DSCH Frame respectively, the 2nd HS-DSCH Frame and the 3rd HS-DSCH Frame, and in each HS-DSCH Frame, carry corresponding dispatching priority information.
Here, the MAC-d entity carries the highest scheduling precedence information of determined control PDU in a HS-DSCH Frame, such as dispatching priority 15 information, in the 2nd HS-DSCH Frame, carry the inferior high scheduling precedence information of determined data retransmission PDU, such as dispatching priority 14 information, carrying the dispatching priority information of determined New Development data PDU in the 3rd HS-DSCH Frame, is 10 information such as dispatching priority.
Step 208:MAC-d entity is sent to MAC-hs entity in the base station with a HS-DSCH Frame, the 2nd HS-DSCH Frame and the 3rd HS-DSCH Frame.
Step 209: the MAC-hs entity in the base station is distributed to the control PDU in each HS-DSCH Frame, data retransmission PDU and New Development data PDU data in the formation of the corresponding dispatching priority of corresponding current receiver in self according to the dispatching priority information of carrying in the HS-DSCH Frame, the 2nd HS-DSCH Frame and the 3rd HS-DSCH Frame that receive.
Here, because the dispatching priority that carries in the HS-DSCH Frame is the highest, such as being 15, the dispatching priority that carries in the 2nd HS-DSCH Frame is inferior high, such as being 14, the dispatching priority that carries in the 3rd HS-DSCH Frame is minimum relatively, such as being 10, then the MAC-hs entity in the base station is promptly controlled PDU with the data in the HS-DSCH Frame, and the dispatching priority that is distributed to corresponding current receiver in self is in the highest formation, such as being formation 1, with the data in the 2nd HS-DSCH Frame, i.e. data retransmission PDU, the dispatching priority that is distributed to corresponding current receiver in self is in time high formation, such as being formation 2, with the data in the 3rd HS-DSCH Frame, promptly the New Development data PDU is distributed in the formation of the corresponding dispatching priority 10 of corresponding current receiver in self.
After this, a because HS-DSCH Frame, control PDU in the 2nd HS-DSCH Frame and the 3rd HS-DSCH Frame, data retransmission PDU and New Development data PDU have been distributed in the dispatching priority formation from high to low successively, therefore, when the MAC-hs entity in subsequent base stations is dispatched each formation of corresponding current receiver, then can be according to dispatching priority, scheduling controlling PDU place formation successively, data retransmission PDU place formation and the place formation of New Development data PDU, thereby can guarantee that data retransmission PDU and control PDU are preferentially sent to UE, reduce data retransmission PDU and in the MAC-hs entity, wait for the time that is scheduled, avoid the UE call drop and improve downlink transmission data rate greatly with control PDU.

The concrete setting up procedure of this step comprises:
At first, according to the existing method of determining a kind of professional downlink data dispatching priority,, determine the dispatching priority of the New Development data PDU of this kind business promptly according to a kind of type of service and Business Processing priority thereof of business.
Such as, according to being that the dispatching priority of the New Development data PDU of 6,7 and 8 not business of the same race sets gradually the dispatching priority 9,8 and 7 into from high to low with Business Processing priority in the interaction service shown in the table 1.
Secondly, a kind of control PDU of business and the dispatching priority of data retransmission PDU are set equate, and for being higher than any one dispatching priority of New Development data PDU dispatching priority.
Such as, for Business Processing priority in the interaction service is 6 business, and the dispatching priority of its New Development data PDU is 9, so, the dispatching priority that the control PDU of this kind business and data retransmission PDU can be set equates, in the dispatching priority 15 to 10 any one.For another example, be 8 business for Business Processing priority in the interaction service, the dispatching priority of its New Development data PDU is 7, so, the control PDU of this kind business and the dispatching priority of data retransmission PDU can be set equate, be in 15 to 8 any one.
Equating to be the highest scheduling priority 15 with the dispatching priority of control PDU that any one business is set and data retransmission PDU below is that example illustrates concrete business realizing process.
Step 302: in the MAC-DATA request primitive, increase a type bit that is used to indicate the PDU type in advance, and control PDU, data retransmission PDU and New Development data PDU difference corresponding first kind offset, second types value and the 3rd types value are set.
Step 303: when sending downlink data, RLC entity among the RNC uses 2 MAC-DATA request primitives, on the type bit of MAC-DATA request primitive 1, write first or second types value, and with data retransmission PDU and control PDU be carried in the MAC-DATA request primitive 1, and, on the type bit of MAC-DATA request primitive 2, write the 3rd types value, and the New Development data PDU is carried in the MAC-DATA request primitive 2.
Here, owing to set in advance the highest scheduling priority 15 of the identical equal correspondence of dispatching priority of data retransmission PDU and control PDU, that is to say, data retransmission PDU and control PDU can not distinguish the priority of scheduling in follow-up process of transmitting, therefore, RLC entity among the RNC can write any one types value among data retransmission PDU and the control PDU on the type bit of MAC-DATA request primitive 1, that is to say, writes first kind offset or second types value all can.
RLC entity among the step 304:RNC is sent to MAC-d entity among the RNC with each MAC-DATA request primitive.
After MAC-d entity among the step 305:RNC receives each MAC-DATA request primitive that the RLC entity sends, according to the types value on the type bit in each MAC-DATA request primitive, obtain the data retransmission PDU and the control PDU that carry in the MAC-DATA request primitive 1, and obtain the New Development data PDU of carrying in the MAC-DATA request primitive 2.
Here owing to be the first kind offset or second types value on MAC-DATA request primitive 1 type bit, therefore, the MAC-d entity then can know carry in the MAC-DATA request primitive 1 for retransmitting data PDU and controlling PDU.Owing to is the 3rd types value on MAC-DATA request primitive 2 type bit, therefore, the MAC-d entity then can know carry in the MAC-DATA request primitive 2 be the New Development data PDU.
MAC-d entity among the step 306:RNC is according to the dispatching priority of the New Development data PDU that sets in advance, data retransmission PDU and control PDU, determine the dispatching priority of the current New Development data PDU of obtaining, and the dispatching priority of data retransmission PDU and control PDU.
Here, MAC-d entity among the RNC is defined as the dispatching priority of the data retransmission PDU that obtained and control PDU the highest, and determines the dispatching priority of this New Development data PDU according to the type of service of the New Development data PDU of being obtained and the RLC entity corresponding service processing priority of sending this New Development data PDU.
Data retransmission PDU that the utilization of step 307:MAC-d entity is obtained and control PDU generate a HS-DSCH Frame, and utilize the New Development data PDU of being obtained to generate the 2nd HS-DSCH data, and in each HS-DSCH Frame, carry corresponding dispatching priority information.
Here, the MAC-d entity carries the highest scheduling precedence information of determined data retransmission PDU and control PDU in a HS-DSCH Frame, carries the dispatching priority information of determined New Development data PDU in the 2nd HS-DSCH Frame.
Step 308:MAC-d entity is sent to MAC-hs entity in the base station with a HS-DSCH Frame and the 2nd HS-DSCH Frame.
Step 309: the MAC-hs entity in the base station is according to the dispatching priority information of carrying in a HS-DSCH Frame that receives and the 2nd HS-DSCH Frame, data retransmission PDU in the one HS-DSCH Frame and control PDU are distributed in the formation of the highest dispatching priority of corresponding current receiver in self, the New Development data PDU in the 2nd HS-DSCH Frame is distributed in the formation of the corresponding dispatching priority of corresponding current receiver in self.
After this, when the MAC-hs entity in the base station is dispatched each formation of corresponding current receiver, then can be according to dispatching priority, preferentially data retransmission PDU and control PDU are sent to UE simultaneously, reduce data retransmission PDU and in the MAC-hs entity, wait for the time that is scheduled, avoid the UE call drop and improve downlink transmission data rate greatly with control PDU.
In the foregoing description 2, because the dispatching priority of set data retransmission PDU and control PDU equates to be the highest dispatching priority, therefore, to retransmitting data PDU and controlling PDU and distinguish, be about to data retransmission PDU and control PDU be carried in the MAC-DATA request primitive, and utilize data retransmission PDU and control PDU to generate a HS-DSCH Frame, make and the priority orders of not distinguishing transmission between data retransmission PDU and the control PDU only got final product by preferential the transmission at the New Development data PDU.
It is identical with the principle of the foregoing description 1 and embodiment 2 described processes with the specific implementation process of control PDU that the present invention adopts self-defining request primitive to carry data retransmission PDU.
In the various embodiments described above, described control PDU, data retransmission PDU and New Development data PDU belong to a kind of business, that is to say, the foregoing description is described is at a kind of business, make the control PDU with a kind of business, the dispatching priority of data retransmission PDU be higher than the New Development data PDU, so that the specific implementation process that is preferentially sent with respect to the New Development data PDU with a kind of control PDU and data retransmission PDU of business.The present invention is directed to different service types, make the dispatching priority of control PDU, the data retransmission PDU of any one type of service all be higher than the New Development data PDU of any one type of service, so that the control PDU of any one type of service and data retransmission PDU are identical with the principle of the foregoing description process with respect to the process that the New Development data PDU of any one type of service is preferentially sent.
