Description

Transmission method, system and the equipment of the professional MBMS of a kind of multicast/broadcast

Technical field

The present invention relates to communication technical field, relate in particular to wireless communication field based on DSCH Downlink Shared Channel.

Background technology

Existing MBMS (Multimedia Broadcast/Multicast Service, broadcasting/packet service)) UTRAN of Zhi Chiing (Universal Terrestrial Radio Access Network network) side MAC (media access control layer) structure mainly comprises MAC-hs (access control of high speed shared medium) entity and MAC-c/sh/m (public/as to share/access control of multicast and broadcast medium) entity as shown in Figure 1.

Wherein, the MAC-c/sh/m entity is in order to finish the MBMS business, increased MACm (access control of the multicast and broadcast medium) entity with multimedia broadcasting multiple spot function on original MAC-c/sh (public/the shared medium access control) entity.The MAC-c/sh/m entity has following function:

Add MBMS-ID (increase the MBMS sign, so the corresponding corresponding logic channel of described MBMS sign to some degree, also can be called Logic Channel Identifier): be positioned at the MBMS-ID territory at MAC head place, in order to distinguish the MBMS type of service;

TCTF MUX (the destination channel type field is multiplexing): be used to show the mapping relations of logic channel and transmission channel, promptly add the destination channel type field, and in type field, fill out corresponding numerical value at the data head;

Scheduling/buffer memory/grade is handled: 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.

TFC selection (combinations of transport formats selection): the compound mode of selecting transformat, so that with MTCH (MBMS point-to-multipoint transmission channel, carry the MBMS data) and MCCH (MBMS point-to-multipoint control channel, the control information of carrying MBMS data characterizes the feature that MTCH goes up the MBMS data message) be mapped on the FACH (forward access channel).

The MAC-hs entity mainly is responsible for finishing HSDPA.HSDPA is meant that high speed downlink packet inserts, it be on satisfying/the asymmetric demand of downstream data traffic and a kind of modulation and demodulation algorithm of proposing, it can bring up to 10Mbps to downstream data traffic speed under the situation that does not change the WCDMA network configuration of having built.

In the existing MBMS business, the method for MBMS transfer of data is:

The high level of step 1, UTRAN 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 step 3, the 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, by reading the type of data M BMS-ID recognition data on the MTCH channel, again the data on MCCH and the MTCH channel are sent to the high level of UE side correspondence.

Can draw by above analysis, 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't utilize the high speed data transfer characteristic of HSDPA to realize MBMS, the transmission rate of therefore existing MBMS is lower;

In addition, the data packet head of MBMS because the TCTF (logical channel type) in packet header and the capacity of MBMS-ID (Logic Channel Identifier) have the 0-12 bit, has taken interface-free resources, thereby has reduced the data capacity of each bag shown in accompanying drawing 2 and accompanying drawing 3.

Embodiment

Be elaborated to accompanying drawing 11 pairs of described methods of the embodiment of the invention, system and equipment below in conjunction with accompanying drawing 4.

At first the described method of the embodiment of the invention is described, comprising:

Be provided with the high speed shared data sending entity, be provided with the high speed shared data receiving entity in UTRAN (Universal Terrestrial Radio Access Network network) side in UE (subscriber equipment) side, described high speed shared data sending entity of the embodiment of the invention and high speed shared data receiving entity can be the MAC-mhs entity in specific implementation process of the invention process, described MAC-mhs entity is identical with existing MAC-hs entity part function.

Logic channel is mapped to transmission channel, that is, the UTRAN side is mapped to the logic channel MCCH and the logic channel MTCH of UTRAN side on the transmission channel HS-DSCH (high speed shared data channel) of UTRAN side by the high speed shared data sending entity; The UE side is mapped to the MCCH and the MTCH of UE side on the transmission channel HS-DSCH of UE side by the high speed shared data receiving entity.

The process of MBMS data packet transmission specifically comprises as shown in Figure 4:

Step 41, before sending the MBMS packet, the relation information of the logic channel that the physical resource and send of UTRAN side by rrc layer (the 3rd layer of UTRAN interface protocol, radio resource control layer) signaling UE:MBMS packet uses between the two; Described relation information comprises a kind of of following information at least: send the size of channel code, modulation system, transmission interval and the MBMS packet of the use of MBMS packet, the subcarrier that transmission MBMS packet uses etc.; Described MBMS packet comprises: MCCH packet and/or MTCH packet; Described logic channel comprises: logic channel MCCH is used to carry the MCCH packet; Logic channel MTCH is used to carry the MTCH packet.

Step 42, network send the MBMS packet, the UTRAN side rlc layer (wireless chain control layer in the UTRAN interface protocol second layer, rlc layer is by transmitting data between the MAC layer in the logic channel and the UTRAN interface protocol second layer) the MBMS processing data packets that obtains is finished after, the MBMS packet is sent to the high speed shared data sending entity of UTRAN side by logic channel MTCH and/or logic channel MCCH.Described processing comprises to be cut apart or cascade, adds actions such as rlc layer packet header, and prior art has ripe solution, repeats no more herein.

The high speed shared data sending entity of step 43, UTRAN side is judged the MBMS packet that receives: be MTCH packet or MCCH packet, then MTCH packet and/or MCCH packet are distinguished according to set MBMS grade, the MCCH storage that grade is identical is in same MCCH formation, and/or, in the same MTCH formation of MTCH storage that grade is identical.

After the header packet information of the high speed shared data sending entity of step 44, UTRAN side with described MTCH packet and/or the last necessity of MCCH packet interpolation, send the MBMS packet with HSDPA or LTE (long-term evolving network) data transfer mode to the MAC-mhs of UE side entity, the existing in the prior art ripe solution of described HSDPA or LTE data transfer mode repeats no more here; The process of described interpolation header packet information specifically comprises:

Whether the high speed shared data sending entity of UTRAN side will retransmit according to the MBMS packet judges whether that needs add the TSN sequence number to the packet in each MCCH class queue or to the packet in the MTCH class queue, do not retransmit if do not carry out the MBMS packet, add the TSN sequence number then for the MBMS packet; Retransmit if carry out the MBMS packet, just add TSN according to class queue respectively, here, each formation takies a TSN space.Whether described packet will retransmit is that traffic performance by MBMS is determined.

Wherein, the MAC form of MBMS packet as shown in Figure 5, wherein, a retransmits for not needing, and does not add the MAC form of TSN sequence number; B has added the MAC form of TSN sequence number for needs retransmit in packet header.Owing to do not need to add logical channel type and Logic Channel Identifier again in the MCCH of the embodiment of the invention or the MTCH packet packet header, and only when needs retransmit, just add the TSN sequence number, so improved the data capacity of each packet.

The high speed shared data sending entity sends to the UE side by the HS-DSCH channel respectively with MTCH packet and MCCH packet then, if have only MTCH packet or MCCH packet, just send on the high speed shared data receiving entity of UE side by the HS-DSCH channel.Sending method has two kinds: first method is to use the transmission form of regulation in official hour, the size of the channel code that the transmission packet uses in this mode, modulation system, transmission interval and MBMS packet etc., all before this MBMS transfer of data begins by rrc layer notice UE, at this moment sending data does not need to use HS-SCCH (High-Speed Shared Control Channel) channel to tell UE the how data of demodulate reception.Second kind is to carry out dynamic dispatching, the high speed shared data entity is by the scheduler (described scheduler can adopt the scheduler of MAC-hs in the prior art) of MAC-mhs entity, select the MBMS packet that will send according to predetermined rule, send channel code that the MBMS packet uses and modulation system and all will tell UE the how data of demodulate reception, and to carry logical channel type in HS-SCCH be the data of MCCH or the data of MTCH with the MBMS packet that indicates transmission by the HS-SCCH channel.
