Need to prove, in one embodiment of the invention, no matter whether described terminal determines the target TB size of VoIP data to be transmitted by uplink authorization, when described terminal is carried out the VoIP transfer of data, all need the scheduling of the uplink authorization that the base station issues, know that in order to make described terminal which uplink authorization is the uplink authorization of the transmission of these VoIP data of scheduling, can carry TB size in the uplink authorization, in the Logic Channel Identifier at least one, the target TB size of these VoIP data that described terminal will have been determined and the TB size in the uplink authorization compare, perhaps, the Logic Channel Identifier of these VoIP data that described terminal will have been determined and the Logic Channel Identifier in the uplink authorization are compared, when both are identical, described terminal just can determine that this uplink authorization is the uplink authorization of the transmission of these VoIP data of scheduling, and then described terminal is sent VoIP data at the dispatching down distributing of this uplink authorization.

In the present embodiment, described uplink authorization can be the uplink authorization of PDCCH indication, perhaps is the semi-static uplink authorization of configuration, and described empty overhead condensed instruction is preferably radio resource control RRC signaling.

Below by specific embodiment the method that enhancing of the present invention VoIP data uplink covers is elaborated.

As shown in Figure 3, the method that the embodiment of the invention three provides a kind of VoIP of enhancing data uplink to cover comprises the steps:

Target TB size is determined in step 31, base station.

In the present embodiment, concrete, its AMR Codec pattern can be determined according to the described speech frame that obtains in advance in described base station, determines the speech frame quiet lotus corresponding with described AMR Codec pattern then, and then determines the TB size that eats dishes without rice or wine to support according to the quiet lotus of described speech frame.For example, determine that when described base station the AMR Codec pattern of the described speech frame that obtains in advance is 7.4kbps, can determine that by question blank 1 the quiet lotus of the speech frame corresponding with 7.4kbps is 20 bytes.According to the definition of existing LTE physical layer protocol TS36.213, TB size can only be one of 18 bytes, 22 bytes, 26 bytes, 28 bytes, 32 bytes and 41 bytes.So described base station can only be chosen with one of the most approaching, bigger slightly than described speech frame payload above-mentioned value of described speech frame payload as TB size.Therefore, described base station determines that described target TB size is 22 bytes.

Table 1

Step 32, described base station send empty overhead condensed instruction and uplink authorization to terminal.

Wherein, described empty overhead condensed instruction comprises the indication of the sign of described logic channel, described empty overhead compress mode and the indication of described target TB size, carries the TB size identical with the target TB size that indicates in the described empty overhead condensed instruction in the described uplink authorization.After described terminal receives uplink authorization, can compare according to the target TB size that indicates in the TB size in the uplink authorization and the described empty overhead condensed instruction, thereby determine that this uplink authorization is the uplink authorization of this VoIP transfer of data of scheduling.

Described empty overhead condensed instruction can be the RRC signaling, and described uplink authorization can be the uplink authorization of PDCCH indication, the perhaps semi-static uplink authorization for disposing.

The sign of step 33, the described logic channel of described terminal, determine the logic channel of VoIP data to be transmitted, indication according to the described empty overhead compress mode in the empty overhead condensed instruction, determine the empty overhead compress mode of VoIP data to be transmitted, and according to the indication of the described target TB size in the empty overhead condensed instruction, determine the target TB size of VoIP data to be transmitted.

Need to prove, in embodiments of the present invention, how described terminal determines that logic channel, empty overhead compress mode and the object transmission piece size TB size of VoIP data to be transmitted do not limit, and can also have other modes, see preamble for details and describe, repeat no more here.

Step 34, described terminal be according to described definite target TB size, the empty overhead of the VoIP data to be transmitted on the described definite logic channel compressed according to described definite empty overhead compress mode, to obtain target VoIP data.

In the present embodiment, described terminal can be carried out corresponding squeeze operation according to the type of described VoIP data to be transmitted.

As shown in Figure 4, when described VoIP data to be transmitted are speech frame, described terminal at first removes RTP header, UDP header, the IP header of described speech frame, then the speech frame that removes after the operation is encrypted, and the speech frame after encrypting is only increased the PDCP head of 1 byte.Because described voice frame size is 20 bytes, just can guarantee that described target TB size is 22 bytes so described terminal only need increase the PDCP layer Padding (padding data) of 1 byte.

When described VoIP data to be transmitted were the SID frame, described terminal at first removed RTP header, UDP header, the IP header of described SID frame, then the SID frame that removes after the operation was encrypted, and the SID frame after encrypting was only increased the PDCP head of 1 byte.Because the size of described SID frame is 7 bytes, just can guarantee that described target TB size is 22 bytes so described terminal only need increase the PDCP layer Padding of 14 bytes.

Present embodiment increases described PDCP head to described terminal and does not limit with the operating sequence of carrying out described PDCP layer filling.

Wherein, described PDCP head comprises 1bit D/C territory and 7bitPDCP SN territory.Described D/C indicates in the territory type of described VoIP data to be transmitted.Concrete, can determine that by described D/C territory described VoIP data to be transmitted are speech frame or SID frame.In addition, when described D/C territory expands to 2bit, described PDCP SN territory boil down to 6bit can be taken 1 byte to guarantee described PDCP head.

As seen from Figure 4, described target VoIP data are MAC PDU.

The scheduling of the uplink authorization that step 35, described terminal send according to described base station sends to the base station by at least 1 sub-frame of uplink with described target VoIP data.

Step 36, described base station receive described target VoIP data, according to the empty overhead compress mode of described target VoIP data described target VoIP data are reduced processing, obtain the VoIP data to be transmitted before the described terminal compression.

Also with reference to shown in Figure 4, because described terminal does not increase the MAC head when described VoIP data to be transmitted are compressed, so base station MAC layer directly is submitted to the MAC PDU that receives the rlc layer of described logic channel, does not carry out Demultiplexing (demultiplexing) and handle.Simultaneously, because described terminal does not increase the RLC head yet, so described base station can utilize low 5 characters among the described PDCP SN that described target VoIP data are reordered.

Further, described base station removes Padding and the described PDCP head of the described PDCP layer in the target VoIP data after reordering according to the type of the described target VoIP data of the D/C territory of described PDCP head indication.Concrete, when described target VoIP data were speech frame, the target VoIP data of described base station after to described reordering removed 1 byte Padding and described PDCP head; When described target VoIP data were the SID frame, the target VoIP data of described base station after to described reordering removed 14 byte Padding and described PDCP head.

At last, the target VoIP data that described base station will remove after the operation are decrypted, again according to receive an in advance or last up VoIP packet that comprises RTP header, UDP header and IP header that has reduced, RTP header, UDP header and the IP header of the target VoIP data after the reduction deciphering, and then obtain the preceding VoIP data to be transmitted of described terminal compression.

By above description as can be seen, terminal is compressed the VoIP data to be transmitted of the logic channel of appointment according to TB size according to the empty overhead compression scheme, obtain target VoIP data, by at least 1 sub-frame of uplink described target VoIP data are sent to the base station again, described target VoIP data are reduced in described base station to be handled to obtain described VoIP data to be transmitted, owing to only comprise part air protocol header through the target VoIP data after the squeeze operation, reduced the size of target VoIP data, under identical Power Limitation, promoted up successful transmission range, thereby solved the empty problem of up covering effectively, strengthened the up covering of VoIP data.Therefore, utilize the technical scheme of the embodiment of the invention, strengthened the up covering of VoIP data.

In another specific embodiment of the present invention, described terminal adopts different empty overhead compress modes, and at this moment, in step 34, described terminal can be carried out corresponding squeeze operation according to the type of described VoIP data to be transmitted.

As shown in Figure 5, when described VoIP data to be transmitted are speech frame, described terminal at first removes RTP header, UDP header, the IP header of described speech frame, then the speech frame that removes after the operation is encrypted, and the speech frame after encrypting is only increased PDCP head and the 1 byte MAC head of 1 byte.Because the size of described speech frame is 20 bytes, so described terminal no longer increases described PDCP layer Padding or described MAC layer Padding just can guarantee that described target TB size is 22 bytes.

When described VoIP data to be transmitted are the SID frame, described terminal at first removes RTP header, UDP header, the IP header of described SID frame, then the SID frame that removes after the operation is encrypted, and the SID frame after encrypting is only increased PDCP head and the 1 byte MAC head of 1 byte.Because the size of described SID frame is 7 bytes, so described terminal only increases by 13 bytes described PDCP layer Padding or the described MAC layer of 13 bytes Padding just can guarantee that described target TB size is 22 bytes.In actual applications, described terminal can be carried out the operation of PDCP layer earlier, carries out the operation of MAC layer again.Concrete, described terminal can increase the PDCP head of 1 byte earlier, carries out the described PDCP layer of 13 bytes again and fills, and increases by 1 byte MAC head then; Perhaps, described terminal also can be carried out the PDCP layer filling of 13 bytes earlier, increases the described PDCP head of 1 byte again, increases by 1 byte MAC head then; Perhaps, described terminal also can only increase the PDCP head of 1 byte, increases by 1 byte MAC head again, carries out the described MAC layer of 13 bytes then and fills; Perhaps, described terminal also can only increase the PDCP head of 1 byte, carries out 13 byte MAC layers again and fills, and increases the described MAC head of 1 byte then.

Wherein, present embodiment increases described PDCP head to described terminal and carries out the step order that described PDCP layer fills and do not limit.

Wherein, described PDCP head comprises 1bit D/C territory and 7bitPDCP SN territory.Described D/C indicates in the territory type of described VoIP data to be transmitted.In addition, when described D/C territory expands to 2bit, described PDCP SN territory boil down to 6bit can be taken 1 byte to guarantee described PDCP head.

As seen from Figure 5, described target VoIP data are MAC PDU.

At this moment, in step 36, also with reference to shown in Figure 5, increased described MAC head when owing to described terminal described VoIP data to be transmitted being compressed, so the MAC SDU that base station MAC generates described target VoIP data is submitted to the rlc layer of the logic channel of described MAC head indication.Simultaneously, because described terminal does not increase the RLC head, so described base station can utilize low 5 characters among the described PDCP SN that described MAC SDU is reordered.

Further, described base station removes described MAC head and the described PDCP head of the target VoIP data after reordering and the padding data of the padding data of described MAC layer or described PDCP layer according to the type of the described target VoIP data of the D/C territory of described PDCP head indication.When described target VoIP data were speech frame, described base station only removed described MAC head and described PDCP head to the target VoIP data after reordering.When described target VoIP data were the SID frame, if described SID frame is when compression the time has only increased described PDCP layer and fills, described base station removed the described PDCP layer Padding of described MAC head, described PDCP head and 13 bytes to the target VoIP data after reordering; If described SID frame has only increased described MAC layer when compressing when filling, described base station removes the filling of the described MAC layer of described MAC head, 13 bytes and described PDCP head to the target VoIP data after reordering.

As shown in Figure 6, when described VoIP data to be transmitted are speech frame, described terminal at first removes RTP header, UDP header, the IP header of described speech frame, then the speech frame that removes after the operation is encrypted, and the speech frame after encrypting is only increased the PDCP head of 2 bytes.Because described voice frame size is 20 bytes, just can guarantee that described TB size is 22 bytes so described terminal no longer increases PDCP layer Padding.

When described VoIP data to be transmitted were the SID frame, described terminal at first removed RTP header, UDP header, the IP header of described SID frame, then the SID frame that removes after the operation was encrypted, and the SID frame after encrypting was increased the PDCP head of 2 bytes.Because the size of described SID frame is 7 bytes, just can guarantee that described TB size is 22 bytes so described terminal only increases the described PDCP layer Padding of 13 bytes.

Wherein, described PDCP head comprises that (expansion, Extension) territory, 7bitPDCP SN territory and 8bitPT territory perhaps comprise 2bit D/C territory and 6bit PDCP SN territory to 1bit E.Whether described E territory is used to refer to described PDCP head expansion.Described PT territory is the expansion of described PDCP head, is used to refer to the type of described VoIP data to be transmitted.

As seen from Figure 6, described target VoIP data are MAC PDU.

At this moment, in step 36, also with reference to shown in Figure 6, do not increase the MAC head when owing to described terminal described VoIP data to be transmitted being compressed, so base station MAC layer directly is submitted to the MAC PDU that receives the rlc layer of described logic channel, does not carry out Demultiplexing and handle.Simultaneously, owing to described terminal also increase RLC head useless, so described base station can utilize low 5 characters among the described PDCP SN that described target VoIP data are reordered.

Further, described base station removes PDCP layer Padding and the described PDCP head of the target VoIP data after reordering according to the type of the described target VoIP data of expansion (the being the PT territory) indication of described PDCP head.Concrete, when described target VoIP data were speech frame, described base station removed the PDCP head of 2 bytes to the target VoIP data after reordering.When described target VoIP data were the SID frame, the target VoIP data of described base station after to described reordering removed the PDCP head of 2 bytes and the PDCP layer Padding of 13 bytes.

At last, the target VoIP data that described base station will remove after the operation are decrypted, again according to receive an in advance or last up VoIP packet that comprises RTP header, UDP header and IP header that has reduced, reduce RTP header, UDP header and the IP header that removes the target VoIP data after the operation, and then obtain VoIP data to be transmitted before the described terminal compression.
