Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to the data dispatching method in the wireless communication system, be specifically related to a kind of downlink data dispatching method and system.
Background technology
High speed downlink packet access technology (HSDPA) is the technology that 3GPP proposes in order to satisfy the asymmetric demand of up-downgoing transfer of data in the R5 standard, and HSDPA has carried out significant improvement to down link, has imported to pass shared channel (HS-DSCH at a high speed down; High Speed Downlink SharedChannel), (Functional Entity) places Node B with functional entity, and adopt than short coded system such as TTI, 16QAM, AMC (Adaptive Modulation and Coding) and HARQ (Hybrid Automatic Retransmission Query) are the key technology of core, downlink transfer speed can reach 14.4Mbps, improved the section service throughput, increased considerably the data user's quantity on the single-frequency, in addition can also be more intelligently to the application of different priorities and service is sorted and resource is alloted.Along with the end user is more and more higher to the transfer of data performance requirement, the low-cost high-speed data transmittability of HSDPA has more tangible competitive advantage.
When network side has data to send to travelling carriage on the HSDPA channel, radio network controller (RNC) sends to base station node B with data by the Frame Protocol form, comprises the sign H-RNTI of travelling carriage on the HS-DSCH channel and the data that need send to travelling carriage in the Frame.Dispatch the HS-DSCH resource base station, at High-Speed Shared Control Channel (HS-SCCH, High SpeedShared Control Channel) and high-speed physical downlink shared channel (HS-PDSCH) (HS-PDSCH, High SpeedPhysical Downlink Shared Channel) send data.
Network side can dispose the wireless network identification (H-RNTI, HS-DSCH-Radio Network Temporary Identity) of its special use on high speed descending sharing channel for travelling carriage.If network side is not the H-RNTI of travelling carriage configure dedicated, then select a public H-RNTI among the public H-RNTI that travelling carriage can be broadcasted according to its U-RNTI from the system broadcast message of sub-district.
Travelling carriage uses dedicated H-RNTI or the lasting radio frames that receives and monitor on the HS-SCCH channel of public H-RNTI, to obtain to be used for the control information of the data on the demodulation HS-PDSCH channel.Content in the HS-SCCH frame comprises travelling carriage and receives the needed control information of HS-PDSCH channel, as channelization code set, and modulation system, transmission block size, HARQ progress information, redundancy version information, new data indication, mobile station identification or the like.
With reference to Fig. 1, after travelling carriage receives the HS-SCCH frame, if it is consistent to detect the H-RNTI of the mobile station identification information and travelling carriage self in the HS-SCCH frame, then travelling carriage can obtain the control information in the HS-SCCH frame, promptly obtains to be used for the control information of the data on the demodulation HS-PDSCH channel.
Travelling carriage receives data (being real data) to the HS-PDSCH channel after designated time intervals.
In the scheme that prior art provides, if the ability of travelling carriage can not be carried out transfer of data simultaneously and be carried out the alien frequencies isosystem measurement, then need be according to the criterion that consults with network side, in the radio frames of appointment, carry out the alien frequencies isosystem measurement, in specified radio frames, network side is not these travelling carriage dispatching downlink data.Otherwise travelling carriage can cause downlink data to be lost owing to carrying out the alien frequencies isosystem measurement.
In the existing protocol, defined the travelling carriage that has dedicated H-RNTI and calculated measurement opportunity according to following formula:
Travelling carriage calculates the wireless data frame of carrying out the alien frequencies isosystem measurement according to the following equation:
System Frame Number=H-RNTI mod M_REP+n*M_REPH-RNTI is the wireless network identification value of the special use of travelling carriage on high speed descending sharing channel, n=0, and 1,2 ...,
M_REP is the measurement Cycle Length on opportunity,
M_REP=2
kK is measurement Cycle Length on an opportunity coefficient, and travelling carriage obtains this parameter from system broadcast message;
In satisfying the radio frames of above formula, travelling carriage is carried out the alien frequencies isosystem measurement.According to above-mentioned equation, travelling carriage is per 2
kFrame will repeat the alien frequencies isosystem measurement.
Radio network controller (RNC) is carrying out the Physical Shared Channel parameter when being configured to the base station, RNC will measure the opportunity parameter K and be notified to the base station, and when the data that needs sent to travelling carriage as RNC sent to the base station, RNC issued the H-RNTI that can comprise travelling carriage in the Frame of base station.Therefore the System Frame Number that obtains the different system of travelling carriage needs execution alien frequencies can be calculated according to H-RNTI that comprises in the Frame and parameter k in the base station, is not these travelling carriage dispatching downlink data in these radio frames.
In realizing process of the present invention, the inventor finds:
For the base station, as long as receive the measurement parameter K on opportunity that RNC sends, and obtain H-RNTI in the Frame, will calculate travelling carriage according to above-mentioned formula and carry out the required System Frame Number of alien frequencies isosystem measurement, and not be the travelling carriage data dispatching in these radio frames.
And for travelling carriage, have only when using dedicated H-RNTI, just can be according to above formula calculating measurement opportunity.And do not have to be the travelling carriage of its configure dedicated H-RNTI for network side, according to existing protocol, in above measurement opportunity, can not carry out the measurement of the different system of alien frequencies, but can carry out the reception of downlink data.But the base station is in above measurement opportunity, even travelling carriage uses is public H-RNTI, the base station can not issue downlink data for travelling carriage yet.To cause the Data Receiving speed of travelling carriage to reduce like this.
