Description

Multi-user equipment data transmission method and system thereof in the mobile communications network

Technical field

The present invention relates to mobile communication technology, particularly the method and system of multi-user installation transfer of data in the mobile communications network.

Background technology

Third generation universal mobile telecommunications system (Universal Mobile Telecommunications System, be called for short " UMTS ") owing to its strong multimedia communication capacity, high-speed data transmission speed and efficiently many advantages such as the availability of frequency spectrum gain great popularity, and become the developing goal of future mobile communications.One of key property of UMTS technology R5 version is exactly that high speed downlink packet inserts (High SpeedDownlink Packet Access, be called for short " HSDPA "), promptly by adaptive modulation and coding (AdaptiveModulation and Coding, abbreviation " AMC "), mix re-transmission (Hybrid Automatic RepeatreQuest, be called for short " HARQ "), and the series of key techniques such as fast dispatch of base-station node (Node B), realized descending high speed data transfer.

HSDPA is descending to comprise two physical channels, one is high-speed physical downlink shared channel (HS-PDSCH) (HighSpeed Physical Downlink Shared Channel, be called for short " HS-PDSCH "), be used to carry user's data information, another is High-Speed Shared Control Channel (High Speed Shared ControlChannel, be called for short " HS-SCCH "), be used to carry the required signaling of demodulation companion data channel HS-PDSCH.In addition, HSDPA is at a up High-Speed Dedicated Physical Control Channel (the HighSpeed-Dedicated Physical Control Channel that increased, be called for short " HS-DPCCH "), this channel is used to carry the feeding back downlink Frame receives correctness by HS-PDSCH information, perhaps be used for feedback channel quality indication (Channel Quality Indicator is called for short " CQI ").

Under common pattern, subscriber equipment (User Equipment, be called for short " UE ") know whether have Node B to send to its data on the corresponding HS-PDSCH by HS-SCCH, also from HS-SCCH obtain demodulation HS-PDSCH required comprise transformat and resource informations such as parallel code channel number and corresponding spreading code, transmission block size, modulation scheme, Node B then knows by HS-DPCCH whether data are correctly received, if incorrect, will initiate to retransmit, otherwise send new data.

Specifically, at each Transmission Time Interval (Transmission Time Interval, be called for short " TTI ") on, HS-PDSCH can only transmit the data of a UE, UE by monitor HS-SCCH judge corresponding TTI the HS-PDSCH channel bearing whether be one's own data.According to 3GPP standard " TS 25.212 " multiplexed and chnnel coding (Multiplexing and channel coding) " ", the HS-SCCH loaded information comprises: the channel code collection information of 7 bits, the modulation scheme information of 1 bit, the transport block size information of 6 bits, the HARQ procedural information of 3 bits, the redundancy versions of 3 bits and planisphere version information, the new data indication of 1 bit and the high speed descending sharing channel Radio Network Temporary Identifier of 16 bits (HS-DSCH Radio Network TemporaryIdentifier is called for short " H-RNTI ").UE be exactly according to the UE of 16 bits that carry on HS-SCCH sign H-RNTI judge corresponding TTI the HS-PDSCH channel bearing whether be one's own data.

On the other hand, the RRC connection status comprises CELL_DCH (cell dedicated channel status), CELL_FACH (cell forward access channel status), CELL_PCH (cell paging channel status) or URA_PCH (user registration area paging channel state) four sub-states, RNC is by the transfer of control UE between different RRC connexon states, realize effective use of Radio Resource, for example, when UE has mass data to transmit, this UE can use HSDPA and HSUPA to realize high speed data transfer under CELL_DCH, and when UE does not temporarily have data to transmit, then enter other RRC connexon state, thereby reduce taking Radio Resource.

But, transfer between the different RRC connexon states needs long switching time, connect experience in order to make the user obtain continuous business, need prolong the time that UE is in the CELL_DCH state as far as possible, reduce UE the taking that is in the CELL_DCH state in other words as far as possible Radio Resource.For this reason, 3GPP has introduced CPC (Continuously Packet Connected or ContinuousPacket Connectivity in R7, continuous grouping connects) pattern technology, wherein, the method that takies that effectively reduces Radio Resource one of down direction is to adopt the operation of HS-SCCH-less (no HS-SCCH).

In HS-SCCH-less, network side is in advance for being operated in the certain HS-PDSCH channel of UE configuration under the HS-SCCH-less mode, and this HS-PDSCH channel modulation and the coded format that are adopted, when carrying out the coding of HS-DSCH, adopted the specific CRC check of UE (CRC) (being that H-RNTI carries out mould 2 and adds with UE specific I D promptly) to the partial bit of CRC check part, and the transmission first time of data grouping is not sent the control information of HS-SCCH, UE then carries out blind Detecting according to pre-configured modulation and coded format to pre-assigned HS-PDSCH channel, then still adopts HS-SCCH to send specific control information to retransmitting.Because HS-PDSCH has adopted the specific CRC check of UE when transmitting for the first time, so UE can judge and receive one's own data.

Wherein, when carrying out the coding of HS-DSCH (physical channel HS-PDSCH corresponding transmission channel), adopt the specific CRC check of UE as shown in Figure 1, at first generate the CRC check bit of 24 bit long by HS-DSCH transport block data bit, then, last 16 of the CRC check bit of 24 bit long, with the UE specific I D of 16 bit long be that H-RNTI carries out mould 2 and adds (scrambling), the data bit that obtains at last, comprise the CRC check bit that HS-DSCH transport block data bit and UE are specific, carry out chnnel coding and rate-matched processing by common pattern.Like this, UE is after decoding to corresponding HS-PDSCH, only needing with oneself UE specific I D (being H-RNTI) last 16 bits of the CRC check bit of decoded data block to be carried out mould 2 adds, CRC check bit after can obtaining disturbing, operate by CRC check, if CRC check is by (success), show that then the data on this HS-PDSCH correctly receive, and be the data that network side sends to this UE, if CRC check then do not show the data on this HS-PDSCH or do not belong to this UE by (failure), even or the data of this UE but incorrect reception, therefore, UE will abandon the decoded data of described HS-PDSCH.

Because remarkable advantages such as downlink transfer speed is big, propagation delay time is little, HSDPA is by increasing professional the use, based on internet protocol multimedia core network subsystem (IP Multimedia Subsystem, abbreviation " IMS ") packet voice (Voice over IP, abbreviation " VoIP ") technology is exactly typical case wherein, other example also comprises grouping recreation (Game over IP is called for short " GoIP ") business, instant message, PoC (Push-to-talk over Cellular) business or the like.

For carrying VoIP service efficiently, generally adopt the HSDPA/ high speed downlink packet to insert (HighSpeed Uplink Packet Access, be called for short " HSUPA ") bearing mode, wherein HSDPA is used for the VoIP data of bearing downlink direction, and HSUPA is used to carry the VoIP data of up direction.

In the prior art, because HSDPA can only transmit among the UE grouped data in the MAC-hs priority query in a TTI, and it is lower based on the professional total peak rate of the VoIP of HSDPA, if packet data streams different among the VoIP is further segmented the back to be transmitted in different MAC-hs priority queries, to cause each priority query to have lower speed, be far smaller than the transmission bandwidth of HSDPA, cause a large amount of residue transmission bandwidths not to be utilized, and also have data to be transmitted such as a large amount of in other MAC-hs priority queries among many other UE that use the VoIP business among this UE or in this sub-district.

In order to solve the lower problem of transmission bandwidth utilance, proposition is with media interviews control (the Medium Access Control of a plurality of UE, abbreviation " MAC ") layer data is grouped in the method for transmitting behind MAC layer or the physical layer multiplex in a TTI, as shown in Figure 2, thereby effectively improved utilization ratio of wireless resources, and helped improving each small packet service user's such as sub-district VoIP, GoIP capacity.

In order to transmit the multiplexing transmission block of many UE to two or more UE simultaneously, divide into groups pairing UE of each multiplexing MAC layer data is together formed a UE group, be H-RNTI of UE set of dispense, be used to identify this UE group, make the UE in this UE group can be according to the correct packet that receives after multiplexing of H-RNTI.

Yet, such scheme has only been described the transmission problem of UE group under the general mode, be not described in the technical scheme of transmission of the UE group under CPC (Continuously Packet Connected or Continuous Packet Connectivity, the continuous grouping connects) pattern.
