Description
Technical field
The present invention relates to the multimedia broadcasting multicast service (MBMS) in Wideband Code Division Multiple Access (WCDMA) (WCDMA) system, relate in particular to a kind of method of utilizing high rate downlink data bag access technology (HSDPA) to realize MBMS.
Background technology
Present WCDMA system can provide the message transmission rate of the highest 2Mbit/s, supports packet switching and circuit switching at a high speed, and many business based on the internet can be provided.Yet,, need system that higher transmission rate and delay still less are provided for such as asymmetric business of up-downgoing data such as download or Streaming Media classes.In order to satisfy this requirement, WCDMA has done improvement to air interface, has introduced the HSDPA technology, makes it to support the peak rate up to 10Mbit/s.
The HSDPA technology is a kind of important technology that the WCDMA networking later stage improves downlink capacity and data service rate, is enhancing and the evolution of WCDMA at wireless portion.HSDPA has increased the MAC-hs entity newly at medium access control (MAC) layer of base station node B side, and this entity mainly is responsible for handling rapid mixing and is retransmitted (HARQ) and fast dispatch algorithm automatically; In addition, HSDPA has also increased by three new channels on original physical channel, is responsible for transmitting user data, required control information and transmission response and the feedback information etc. of transmission decoding respectively.Introduce the WCDMA wireless portion after the HSDPA technology, its basic structure still is consistent with R99, therefore, supports the terminal of HSDPA technology to coexist in a carrier wave with the R99 terminal, and need not to operate in independently on the carrier wave.
The NodeB side has increased by the two kinds of MAC structures of HSDPA technical support behind the MAC-hs entity:
A kind of for control radio network controller (CRNC) comprises the MAC-c/sh entity, another kind does not comprise the MAC-c/sh entity for CRNC.
As shown in Figure 1, comprised in CRNC under the situation of MAC-c/hs entity, the MAC-hs entity of NodeB side is by the MAC-c/hs entity of CRNC side, and the MAC-d entity with service wireless network controller (SRNC) side is connected again.The MAC-c/hs entity provides the correlation function of HSDPA technology, and Frame Protocol (HS-DSCH FP) is handled data from SRNC to CRNC and the transfer of data between CRNC and the NodeB.
As shown in Figure 2, in CRNC, do not comprise under the situation of MAC-c/hs entity, owing to do not comprise any content relevant among the CRNC with the HSDPA technology, so the MAC-hs entity of NodeB side directly is connected with the MAC-d entity of SRNC.The high speed descending sharing channel of SRNC side (HS-DSCH) user face is directly linked the NodeB side, and promptly SRNC directly links to each other with NodeB.
The newly-increased MAC-hs functional entity of NodeB side mainly is responsible for the fast packet scheduling of HSDPA and the real-time control of HS-DSCH channel.According to the quality condition of wireless channel and etc. data volume and professional factors such as priority level to be launched, the fast packet scheduling algorithm can be realized the optimum allocation of shared resource.The HSDPA technology is placed on the scheduling feature unit in NodeB side rather than the radio network controller (RNC) in order to adapt to the quick variation of wireless channel better, and therefore Transmission Time Interval also shortens in the 2ms.

2. scheduling/grade is handled: according to the grade of HARQ entity and data flow, and the resource of management HS-DSCH.According to the status report that comes from the related uplink signaling, decision is carried out new transfer of data and is still carried out data re-transmission.
3.HARQ: for handling to mix automatically, the user retransmits.
4. transformat and resource merge (TFRC) selection: be that the data on the HS-DSCH channel are selected suitable transformat and resource.
By the MAC-hs entity of UTRAN side, the data that come from the MAC-d entity are through data flow con-trol, scheduling/grade processing, HARQ and TFRC selection etc., to the MAC-hs of UE side entity transmission.
As shown in Figure 4, the MAC-hs entity of UE side has following function:
1.HARQ: handle all tasks relevant with HARQ.
2. queue and rearrangement is distributed (Reordering Queue distribution): give the corresponding buffer memory of resetting according to queue identity with protocol data unit (PDU) route of MAC-hs.
3. reset: the MAC-hs PDU that receives is resequenced according to transmission sequence number (TSN).
4. decompose: decompose MAC-hs PDU.At first, remove the MAC-hs head, solve MAC-d PDU and all fillers; Then, send MAC-d PDU to high level.
After coming from the processing of data through UE side MAC-hs entity of UTRAN side, mail to the high level of UE correspondence.
By Fig. 3 and Fig. 4, the MAC-hs entity has been finished the transfer of data from the UTRAN side to the UE side.
Along with developing rapidly of network, a large amount of multimedia services emerge, and the some of them applied business requires a plurality of users can receive identical data simultaneously, as video request program, video conference, online education and interactive game etc.Above-mentioned mobile multi-media service has characteristics such as data volume is big, longer duration, delay sensitive.In order on the mobile network, to realize multimedia service, WCDMA/ global system for mobile communications (GSM) standardization body has proposed the MBMS business, the point-to-multipoint service that sends data with a data source to a plurality of users is provided in the mobile network, promptly carry out the transmission of multimedia service broadcast multipoint by all users or the group user of common signal channel in the sub-district of Radio Access Network (RAN) side, the realization Internet resources share, make utilization rate of network resource to reach maximization.For RNC, if the MBMS business is supported in the sub-district of its control, then each sub-district all has a MBMS service identifiers (MBMS Service ID) and the pairing MBMS service entities of MBMS service identifiers.For the sub-district of having activated MBMS user being arranged, the information that the MBMS service entities of this sub-district RNC has been preserved the UE that the MBMS business is arranged.Above-mentioned information has comprised UTRAN Radio Network Temporary Identifier (U-RNTI) information of all UE of each MBMS grade at least.
Figure 5 shows that the UTRAN side MAC structure of the existing MBMS support of stipulating in the 3GPP agreement.In order to finish the MBMS business, agreement has increased the MAC m entity with multimedia broadcasting multiple spot function on original MAC-c/sh entity, become the MAC-c/sh/m entity.Agreement has increased by two kinds of logic channels: MBMS point-to-multipoint control channel (MCCH) and MBMS point-to-multipoint transmission channel (MTCH).Wherein MTCH goes up carrying MBMS data message, and MCCH goes up the control information of carrying MBMS data, characterizes the feature that MTCH goes up the MBMS data message.The MBMS data are mapped to forward access channel (FACH) by MCCH and MTCH channel multiplexing, are transmitted to the user by FACH again.
Figure 6 shows that the structure of UTRAN side MAC-c/sh/m entity.This entity is positioned on the CRNC, has following function:
1. increase MBMS sign (add MBMS-ID): for the logic channel of point-to-multipoint type, the MBMS-ID territory that is positioned at MAC head place is in order to distinguish the MBMS type of service;
2. destination channel type field multiplexing (TCTF MUX): be used to show the mapping relations of logic channel and transfer channel, promptly add the destination channel type field, and in type field, fill out corresponding numerical value at the data head;
3. scheduling/buffer memory/grade is handled (Scheduling/Buffering/priority Handling): according to the grade of MBMS data flow and non-MBMS data flow, manage the normal transmission resource of above-mentioned two kinds of data flow.
4. combinations of transport formats is selected (TFC selection): select the compound mode of transformat, so that FACH is mapped on MCCH and the MTCH.
Figure 7 shows that the structure of UE side MAC-c/sh/m entity, the function of this entity is:
1. read MBMS sign (read MBMS-ID): the type of the MBMS data that identification is imported into;
2. destination channel type field demultiplexing (TCTF DEMUX): handle the detection and the deletion in TCTF territory in the MAC head, and the mapping relations of telling logic channel MCCH or MTCH and transmission channel.
In existing MBMS business, the method for MBMS transfer of data is:
The high level of step 1.URAN side by MCCH and MTCH channel with the MAC-c/sh/m entity of MBMS data distributing to the UTRAN side.
The MAC-c/sh/m entity of step 2.UTRAN side at first increases MBMS-ID to the MBMS data on the MTCH channel; Then the data on MCCH and the MTCH channel are carried out the multiplexing operation of TCTF, with the data map of above-mentioned two channels to the FACH channel; Handle and the TFC selection operation by scheduling/buffer memory/grade then, data on the FACH channel are transmitted to the UE side, the UTRAN side is by MBMS informing indication channel (MICH) simultaneously, at the user in each MBMS grade of service, carry out the Radio Paging indication to the UE side, notice UE receives the moment of UTRAN side MBMS data.
After FACH channel on the step 3.UE side MAC-c/sh/m entity receives the MBMS data that come from the UTRAN side, carry out the TCTF de-multiplex operation, the data map on the FACH channel is arrived MCCH and MTCH channel; Then, the type of the MBMS-ID recognition data by reading data on the MTCH channel sends to the data on MCCH and the MTCH channel high level of UE side correspondence again.
The existing shortcoming of MBMS method that realizes is:
1. owing to do not carry the channel of MBMS data between the MAC-c/sh/m entity of UTRAN side and the MAC-hs entity, can't transmit the MBMS data by the MAC-hs entity, promptly can not utilize the HSDPA technology to realize MBMS, and then can't utilize the characteristic of the high speed data transfer of HSDPA, the transmission rate of therefore existing MBMS business is lower.
2. because the UE side receives the MBMS business datum according to time point entrained in the indication of the Radio Paging on the MICH channel, one section time-delay can appear between the time of reception of the delivery time of UTRAN side and UE side, therefore, the transmission time of MBMS business datum is longer, and the processing procedure of UE side is comparatively complicated.

Embodiment
For making purpose of the present invention, technical scheme clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
The present invention is a kind of method of utilizing HSDPA to realize MBMS, its basic thought is: increase the MBMS Data-carrying between the MAC-c/sh/m of UTRAN side entity and UTRAN side MAC-hs entity, in the MAC-c/sh/m entity of UE side and the UE side MAC-hs entity, and in UTRAN side MAC-hs entity, increase MBMS grade processing capacity entity, then send the MBMS data according to the data transfer mode in the HSDPA mechanism.
Particularly, the present invention increases the MBMS Data-carrying by MAC-m configuration (Configuration with MAC-m) by name in advance between the MAC-c/sh/m of UTRAN side entity and UTRAN side MAC-hs entity, be responsible for the MBMS data by the MAC-c/sh/m entity of UTRAN side to the MAC-hs of UTRAN side entity transmission; In the MAC-c/sh/m of UE side entity and UE side MAC-hs entity, increase the MBMS Data-carrying, be responsible for the MBMS data by the MAC-hs entity of UE side to the MAC-c/sh/m of UE side entity transmission.In addition, the present invention has increased MBMS grade processing capacity entity in the MAC-hs of UTRAN side entity, comprise MBMS class queue distribution function entity, two class MBMS data queues, Add MBMS-ID and TFRC selection functional entity, wherein MBMS class queue distribution function entity and two class MBMS data queues are responsible for respectively the data on MCCH, the MTCH channel are distributed and stored; Add MBMS-ID and TFRC selection functional entity are then finished the MBMS data according to HSDPA mechanism and are sent to UE processing before.
Because MBMS provides polytype business, the selected MBMS of different user is difference to some extent, it is MBMS grade difference, therefore the high level of UTRAN side correspondence is before the MBMS transfer of data, MBMS grade according to the user, all users are divided into a plurality of groups, and each user in the wherein same group has identical MBMS grade.At different groups, high level increases user's MBMS class information in the link setup signaling of Iub interface, and issues the channel code information of different High-Speed Shared Control Channel (HS-SCCH) by Iub interface.Comprise parts such as MBMS class information and HS-SCCH channel code in the HS-SCCH channel code information, wherein the HS-SCCH channel code has two effects: the one, show group information, the user who promptly is in the same group has identical channel code, and user's channel code difference in the different group; Another effect is that the UE identify label (UE Identity) entrained to control information in the HS-SCCH channel decoded, and distinguishes the data on MCCH and the MTCH channel.For example, after the decoding of HS-SCCH channel code, UE Identity equals 0xffff and represents the MCCH channel data, and UE Identity equals 0x0000 and then represents the MTCH channel data.
As shown in Figure 8, the present invention utilizes HSDPA to realize that the method for MBMS may further comprise the steps:
The high level of step 801.UTRAN side correspondence has increased the MBMS data distributing in the MAC-c/sh/m entity of MBMS to the UTRAN side.
As shown in Figure 9, the high level of UTRAN side correspondence is handed down to the MAC-c/sh/m entity that the UTRAN side has increased MBMS by MTCH and MCCH channel respectively with the data message and the control information data of MBMS business.In this step and the existing MBMS business to issue data manipulation identical.
The MAC-c/sh/m entity that step 802.UTRAN side has increased MBMS sends to the MAC-hs entity that the UTRAN side has increased MBMS with data by the MBMS Data-carrying of disposing.
In this step, the MAC-c/sh/m entity that the UTRAN side has increased MBMS at first will increase channel logo in the MBMS data of being received, to distinguish MTCH and MCCH channel data.Then, the data on MTCH and the MCCH channel send the MAC-hs entity that the UTRAN side has increased MBMS according to the mode of time-sharing multiplex in the MBMS Data-carrying of passing through the MAC-m configuration that increases.So-called time-sharing multiplex mode, be meant that the time order and function that transmits according to data on MTCH and the MCCH channel transmits, if promptly UTRAN side MAC-c/sh/m entity receives the data on the MTCH channel earlier, then earlier the MTCH data are sent out in the MBMS Data-carrying by the MAC-m configuration.Since the asynchronism(-nization) that MTCH and MCCH channel data transmit, the data that therefore can carry two channels of transmission in the mode of time-sharing multiplex by data.
As shown in figure 10, the MAC-c/sh/m entity that the UTRAN side has increased MBMS has increased MBMS processing capacity entity on the basis of UTRAN side MAC-hs entity shown in Figure 3, and part shown in the empty frame is newly-increased MBMS processing capacity entity among Figure 10.After the MAC-c/sh/m entity that has increased MBMS in the UTRAN side sent the MBMS data, the MAC-hs entity that the UTRAN side has increased MBMS carried out the reception and the processing of MBMS data.At first, to tell these data according to channel logo entrained in the MBMS data be MTCH channel data or MCCH channel data to the UTRAN side MAC-hs entity that increased MBMS; By the MBMS class queue distribution portion in the scheduling/grade processing capacity entity, the data on two channels are distinguished according to user's MBMS grade respectively again; Then, the MCCH channel data that grade is identical is stored in the same formation of MCCH class queue functional entity, and the MTCH channel data that grade is identical is stored in the same formation of MTCH class queue functional entity; Increasing the MBMS-ID functional entity increases the operation of MBMS-ID again to the data in all MTCH class queues; All MCCH class queues and increased data in all MTCH class queues of MBMS-ID after TFRC selects are sent on the HS-DSCH channel.
According to the relevant agreement regulation of HSDPA, the HS-DSCH channel comprises two kinds of channels: HS-SCCH channel and HS-PDSCH channel, the wherein control information of HS-SCCH channel bearing tendency to develop transmission of data, and the defeated data of HS-PDSCH channel bearing tendency to develop.Corresponding to the MBMS business, carrying MBMS control information data on the MCCH channel, and MTCH channel bearing MBMS data, therefore when the present invention realizes MBMS according to HSDPA mechanism, data in the MCCH class queue and the data that increased in the MTCH class queue of MBMS-ID are sent on the HS-PDSCH channel; Their control informations such as size of data then send on the HS-SCCH channel.
The MAC-hs entity that step 803.UTRAN side has increased MBMS sends the MBMS data by HSDPA mechanism to the MAC-hs entity that the UE side has increased MBMS.
According to the agreement regulation, when sending data, at first the control information on the HS-SCCH channel is sent with HSDPA mechanism, so that receiving terminal is carried out according to control information the reception of authentic data is prepared; And then data carried by data on the transmission HS-PDSCH channel.
In this step, the MAC-hs entity that the UTRAN side has increased MBMS sends to the UE side with the control information of MBMS data on the HS-SCCH channel earlier, and this control information comprises MBMS data block size, data level and UE Identity etc.; Then, after through agreement official hour interval, again the MBMS data are sent to UE by the HS-PDSCH channel.The method of above-mentioned transmission MBMS data is with to utilize the HSDPA technology to send the method for other data identical.
The increase of step 804.UE side the MAC-hs entity of MBMS receive the MBMS data come from the UTRAN side, and send the MBMS Data-carrying of these MBMS data by configuration to MAC-c/sh/m entity that the UE side has increased MBMS.
As shown in figure 11, in this step the increase of UE side the MAC-hs entity of MBMS at first receive and come from the control information of MBMS data that the UTRAN side has increased the MAC-hs entity of MBMS by the HS-SCCH channel, and parse various control informations, for example MBMS data block size, formation grade, UE Identity etc.; After through agreement official hour interval, receive HS-PDSCH by HSDPA mechanism and go up real MBMS data; Then, MBMS control information or business datum are sent by the MBMS Data-carrying that the pre-configured UE side of system has increased between the MAC-hs entity of MBMS and the MAC-c/sh/m entity that the UE side has increased MBMS.
The MAC-c/sh/m entity that step 805.UE side has increased MBMS is sent to the MBMS data by the MBMS Data-carrying of configuration the high level of UE side correspondence.
As shown in figure 12, system is in the MAC-c/sh/m of UE side entity, pre-configured two MBMS Data-carryings: one is to connect the Data-carrying that the UE side has increased MAC-hs entity and the UE side MCCH channel of MBMS, and another is that connection UE side has increased the Data-carrying of reading the MBMS-ID functional entity in the MAC-hs entity of MBMS and the MAC-c/sh/m entity that the UE side has increased MBMS.The starting end of above-mentioned two MBMS Data-carryings is identical, all links to each other with the MBMS Data-carrying that the UE side has increased the MAC-hs entity of MBMS.
In this step, the MAC-c/sh/m entity that the UE side has increased MBMS at first receives and comes from the MBMS data that the UE side has increased the MAC-hs entity of MBMS; Then, by entrained UE Idantity in the HS-SCCH channel receiving control information data, tell MTCH or MCCH channel data, if what receive is the MCCH channel data, then these data are sent to the MBMS Data-carrying of leading to the MCCH channel,, then these data are sent to the Data-carrying of reading the MBMS-ID functional entity if what receive is the MTCH channel data, and the MBMS-ID information in reading of data, obtain after the MBMS type of service, send these data to the MTCH channel; At last, the MAC-c/sh/m entity of UE side sends to the MBMS data high level of UE correspondence by MCCH or MTCH channel.
