Description

The method for supporting multimedia broadcast multi-broadcasting business transmission, equipment and system

Technical field

The present invention relates to wireless communication technology fields, and in particular to a kind of side for supporting multimedia broadcast multi-broadcasting business to transmit Method, equipment and system.

Background technique

Within a wireless communication network, the access function that user is provided based on radio reception device accesses wireless network Enjoy communication service.By taking mobile communications network as an example, in user equipment (user equipment, referred to as: UE) and base station (base After station, referred to as: BS) establishing connection, network would generally establish point-to-point unicast bearer for user, to provide user class Communication service, such as audio call, video on demand, file download.

As smart phone and the quick of tablet computer are popularized, user is for mobile video business, application program downloading etc. The demand of data service is growing day by day, and the data traffic of the network carrying also sharply rises.At this point, if continuing to use unicast bearer side Formula, a large amount of unicast bearer will occupy a large amount of Internet resources, be easy to cause network congestion problem.In order to better adapt to These application scenarios, multimedia broadcast multi-broadcasting business (multimedia broadcast multicast service, referred to as: MBMS it) comes into being.MBMS is carried by establishing the multicast of single point-to-multipoint, can be provided in identical to multiple users simultaneously Hold.Therefore, the scene concentrated especially suitable for user interest degree, such as: important sports events live streaming, customization video push, application program Update etc..

Fig. 1 is the deployment schematic diagram of mobile communications network in the prior art, including one or more base stations.Each base station pipe One or more cells (cell) are managed, in Fig. 1 by taking one cell of a BTS management as an example.Several are distributed in each cell User equipment, these user equipmenies and base station can by eat dishes without rice or wine (air interface) connect, can be enjoyed after accessing cell Communication service.By taking sports show as an example, it is assumed that multiple user equipmenies request sports show service simultaneously.Such as the upper left side institute of Fig. 1 Show, base station can transmit body to multiple user equipmenies (UE 1, UE 2, UE 3) respectively by multiple point-to-point unicast bearers Educate the video content of live streaming.Since different unicast bearers can occupy different Internet resources, if the number mistake of user equipment More or Internet resources are limited, then are easy to appear video cardton or interrupt situation, influence the business experience of user.Such as the lower-left Fig. 1 Shown in side, base station can also be carried by the multicast of a single point-to-multipoint, at the same to multiple user equipmenies (UE 1 ', UE 2 ', UE 3 ') the identical video content of transmission.Due to the Internet resources of the occupancy of multicast carrying, hardly with user device quantity Purpose increases and changes.Therefore, the business experience of user can be effectively ensured, and the number of user equipment is more, network money The utilization rate in source is higher.

In long term evolution (long term evolution, abbreviation LTE) system, MBMS transmission includes single cell transmission Mode and MBMS Single Frequency Network (multimedia broadcast multicast service single frequency Network, referred to as: MBSFN) transmission mode.MBSFN transmission refers to, uses identical radio-resource-configuration in multiple cells, The identical data content of simultaneous transmission.As shown in Figure 1, cell 1, cell 2 and cell 3 can be matched using identical radio resource It sets, by base station 1, the video content identical with 3 simultaneous transmission of base station of base station 2.In this way, user equipment (UE4) is receiving in video When appearance, the signal from multiple cells effectively overcomes the dry of minizone such as the multipath signal from a cell It disturbs.Therefore, the gain of MBSFN transmission includes the interference of the minizone of merging gain and the reduction of receiver, thus further Ground improves the business experience of user's (especially Cell Edge User).

In LTE, MBMS is also referred to as the MBMS (evolved MBMS, referred to as eMBMS) of evolution, except being explicitly emphasized that Outside, the application does not distinguish the two.The synchronization zone MBSFN (MBSFN is defined in order to support MBSFN to transmit, in LTE Synchronization area) and the region MBSFN (MBSFN area, referred to as: MA) concept.Base in the synchronization zone MBSFN Station is able to maintain time synchronization, and carries out MBSFN transmission.All cells in the single carrier wave of one base station can only belong to one The synchronization zone MBSFN.MBSFN is transmitted as unit of MA, and MA is made of some cells in the synchronization zone MBSFN, belongs to the institute of the MA There is cell cooperative to complete MBSFN transmission.For example, the cell 1, cell 2 and cell 3 in Fig. 1 can form a MA.One The synchronization zone MBSFN may include one or more MA, can be overlapped between multiple MA, and a cell can belong to more simultaneously A MA.

Fig. 2 is the schematic diagram of MBMS application in the prior art.As shown in Fig. 2, a synchronization zone MBSFN includes three MA (MA 1, MA 2, MA 3).Wherein, MA 1 includes three cells, and MA 2 includes seven cells, and MA 3 includes two cells.MA 1 It partly overlaps with MA 2, MA 2 and MA 3 are adjacent.Wherein, cell 2 and cell 3 had both belonged to MA 1, also belonged to MA 2.

At present in the LTE system of actual deployment, the form for generalling use mixed carrier realizes MBMS transmission.MBMS is participated in pass Defeated cell configures radio resource using time division multiplexing mode, can both support MBMS transmission on the same carrier wave, can also prop up Hold unicast transmission.Such cell is referred to as the Unicast-mixed cell MBMS/ (MBMS/Unicast-mixed cell).With Family equipment needs to synchronize with cell before receiving MBMS data, then obtains the relevant control information of MBMS data.In The Unicast-mixed cell MBMS/, synchronization signal are sent as unit of cell, and the cell mark of the cell is carried in synchronization signal Know (cell identity, referred to as: Cell ID or CI).Different cells sends different synchronization signals, different synchronous letters Number carry different cell IDs.User equipment is synchronized by detecting the synchronizing channel of cell, and is determined unique small Area's mark, and then receive broadcast message.That is synchronizing channel and broadcast channel carries MBMS data and control still as unit of cell The Multicast Channel of information processed is as unit of MA.

In addition, in the LTE standard discussion of early stage, it is also considered that realize MBMS transmission in the form of special carrier, cell can MBMS transmission is carried out exclusively with a carrier wave, which can be described as MBMS special carrier.Such cell is referred to as The dedicated cell MBMS (MBMS-dedicated cell).But up to now, about the specific of the dedicated cell MBMS in LTE standard Scheme is all come to nothing.For example, the transmission process of the synchronizing process of MBMS cell, MBMS data and related control information, is being marked It is still blank out in standard.

In the prior art, it is also discussed about the synchronization scheme of MBMS special carrier.For example, by means of cell it is existing under Row synchronization scheme increases MBMS special carrier in the cell, and the existing carrier wave of the MBMS special carrier He the cell is arranged Keep down-going synchronous.After user equipment and the cell synchronous, it can be realized synchronous with MBMS special carrier.But it is this Scheme has more limitation in actual deployment, it is desirable that the range of MBMS special carrier, less than or equal to the covering of existing cell Range.

In addition, also there is scheme to consider the carrier wave for configuring MBMS special carrier to MBSFN is only supported to transmit, it is believed that former at this time Some cellular concepts need to discuss again, and the method that synchronizing channel and broadcast channel are configured as unit of cell is no longer applicable in.Make For substitution, program suggestion configures synchronizing channel and broadcast channel as unit of MA.In other words, transmission is identical in identical MA Synchronization signal, the synchronization signal carry the unique identification of the MA, different synchronization signals are transmitted between different MA.MA is overlapped The case where, a such as biggish MA is made of multiple lesser MA, completes this by the combination of the covering of these lesser MA The covering of a biggish MA.This biggish MA itself no longer needs to that synchronizing channel or broadcast channel is separately configured.If user sets It is standby to need to access this biggish MA, it can be realized by the broadcast channel and control channel for detecting these lesser MA.

But the program is in actual deployment, however it remains certain restrictions.On the one hand, it is contemplated that this larger MA's covers Lid needs to rely on to exist between these smaller respective coverings of MA, and difference MA and interfere with each other, and the covering of each MA should In view of worst case.Covering requirement for broadcast channel, program suggestion and the covering of the Unicast-mixed cell MBMS/ requirement It is identical.Therefore, in actual deployment, the program is more demanding for the covering of network.On the other hand, the program is for the part MA The case where overlapping, may and be not suitable for.By taking Fig. 2 as an example, MA 1 and MA 2 in Fig. 2 partly overlap.Since MA 2 is not by multiple Other MA composition only configures synchronizing channel in MA 1 and MA 3, then the covering of MA 2 can go out if simply continuing to use the program Existing loophole.In order to avoid such case, it may be necessary to plan the configuration of MA in advance, this will also result in centainly in actual deployment Limitation.

MBMS data is forwarded to eNB by MBMS-GW support, and MBMS-GW can be disposed altogether with P-GW.

As shown in figure 3, the interface between MBMS-GW and eNB is known as M1 interface, it is interface in the user plane, MBMS-GW passes through IP The mode of multicast sends MBMS data to eNB.Interface between MCE and eNB is known as M2 interface, is control plane interface, base M2 interface signaling is transmitted in Flow Control Transmission Protocol (stream control transmission protocol, SCTP), is abided by Follow M2 interface protocol regulation.The interface of MCE and MME is known as M3 interface, is control plane interface, based on SCTP transmitting M3 interface letter It enables, it then follows M3 interface protocol regulation.

In conjunction with Fig. 3, rethink that MA as shown in Figure 2 partly overlaps scene.Assuming that one cell of a BTS management, base The cell that 311 manage of standing belongs to MA1, and the cell that base station 312 manages belongs to MA1 and MA2, and the cell that base station 313 manages belongs to MA2.As stated in the background art, under this MA configuring condition, the prior art is simultaneously not suitable for.In order to guarantee the covering of MA 2, this Inventive embodiments can be considered for MA2, in addition configure synchronizing channel, to guarantee the covering of MA2.Base station 312 is managed For cell, due to belonging to MA1 and MA2 simultaneously, then need to be respectively configured two sets of synchronizing channels.This two sets of synchronizing channels can be by Base station 312 is staggered transmission, but this will cause certain wasting of resources, may be by for the UE in MA marginal position To more interference of adjacent MA.Also, when partly overlapping there are multiple MA, the program will be more complicated, may not most Good solution.

In view of the limitation of the program, another more preferably solution is additionally provided in the embodiment of the present invention.Fig. 4 is A kind of schematic diagram of the communication system for supporting MBMS transmission provided in the embodiment of the present invention.As shown in figure 4, communication system 400 Including the first radio reception device and the second radio reception device.Wherein, the first radio reception device management first community, second Radio reception device manages second community, and first community belongs to the first MBMS single frequency network area MA, and second community belongs to second MA, the first MA are different from the 2nd MA.

Specifically, first radio reception device is used for: obtaining the first MBMS sync id；According to the first MBMS Sync id generates the first MBMS synchronization signal；The first radio resource based on pre-configuration broadcasts the synchronous letter of the first MBMS Number.

Second radio reception device is used for: obtaining the 2nd MBMS sync id；It is marked according to the 2nd MBMS is synchronous Know and generates the 2nd MBMS synchronization signal；The second radio resource based on pre-configuration broadcasts the 2nd MBMS synchronization signal.

Also, the first MBMS sync id and the 2nd MBMS sync id are identical MBMS sync id, First radio resource of the pre-configuration and the second radio resource of the pre-configuration are identical radio resource.

Optionally, communication system 400 further include: wirelessly connect with first radio reception device, described second respectively The core network device for entering equipment connection, is used for: the first radio reception device of Xiang Suoshu sends the first MBMS sync id； The 2nd MBMS sync id is sent to second radio reception device.

Therefore, the first radio reception device and the second radio reception device are broadcasted identical on identical radio resource MBMS synchronization signal.For user equipment, belongs to the MBMS synchronization signal transmitted in the different community of different MA, be equivalent to Synchronization signal from the same cell can either obtain reception and merge gain, can also be different to avoid transmitting between different MA The interference that synchronization signal generates.Therefore, compared with existing MBSFN transmission, the technical solution in the embodiment of the present invention is in reality It is more convenient in deployment, the identical MBMS synchronization signal of more MA cooperation transmissions may be implemented, covering for synchronization signal can either be promoted Lid range can also save transfer resource.

In order to introduce above-mentioned communication system 400 in more detail, radio reception device is illustrated below in conjunction with Fig. 5.Fig. 5 For a kind of schematic diagram of the radio reception device for supporting MBMS transmission provided in the embodiment of the present invention.The radio reception device 500, it can be the first radio reception device or the second radio reception device in communication system 400 shown in Fig. 4.This wirelessly connects Enter equipment 500 and manage first community, the first community belongs to the first MA.

As shown in figure 5, the radio reception device 500 includes communication interface 510, transmitter 520 and processor 530.Its In, which may include: wireless interface and wireline interface.Wherein, wireless interface can refer to antenna, can also be with Refer to the logic or physical interface of connection antenna.In addition, radio reception device 500 can also include receiver 540, memory 550 etc..Memory 550 may include read-only memory and random access memory, and provide instruction sum number to processor 530 According to.Processor 530 controls the operation of radio reception device 500, and processor 530 can also be known as central processing unit (Central Processing Unit, referred to as: CPU).In specific application, transmitter 520 and receiver 540 may be coupled to communication interface 510.The various components of radio reception device 500 are coupled by bus system 50, and it includes number that wherein bus system 50, which is removed, It can also include power bus, control bus and status signal bus in addition etc. except bus.But for the sake of clear explanation, Various buses are all designated as bus system 50 in figure.

In embodiments of the present invention, the radio reception device 500 may include:

Wireless interface 510, the transmitter 520 being connect with the wireless interface 510, and the place being connect with the transmitter Manage device 530.The processor 530 is for controlling the radio reception device 500: obtaining MBMS sync id；According to described MBMS sync id generates MBMS synchronization signal；And the radio resource based on pre-configuration, broadcast the MBMS synchronization signal.Its In, the MBMS sync id, the radio resource of the pre-configuration is also applied for second community, and the second community belongs to second MA, the first MA are different from the 2nd MA.

The second community can be by other radio reception device management except radio reception device 500.Do not consider with When the compatibility of current LTE protocol, second community can also be managed by radio reception device 500.

In actual deployment, which can be the sync id individually designed for support MBMS transmission. The number of MBMS sync id can have multiple, and each sync id uniquely indicates a MBMS synchronization signal.The synchronous letter of MBMS Number number, sequence type, sequence length and sequence value and the corresponding of MBMS sync id and MBMS synchronization signal close System, can be arranged by communication protocol.It, can be same according to the MBMS after radio reception device receives a MBMS sync id Step mark, a uniquely generated MBMS synchronization signal.Similarly, the radio resource of the pre-configuration, can also be by the communication protocols View is arranged.It is and current it can be appreciated that the MBMS synchronization signal and at least one of radio resource of communication protocol agreement In LTE communication system be used for unicast transmission synchronization signal and radio resource, should different from, so that user equipment is not having In the case where prior information, it can know that current communication networks support MBMS transmission.

Support the user equipment of the communication protocol, the MBMS that on the radio resource of pre-configuration, can search for broadcast is synchronous Signal.For example, user equipment can be based on sequence related detecting method, the MBMS synchronization signal made an appointment using communication protocol It is related to make time domain to the signal received.When the relevant peak value of time domain is more than some threshold value, that is, it can determine that receive MBMS same Signal is walked, and obtains downlink timing and MBMS sync id accordingly.

Optionally, in a kind of optional embodiment, which is the 2nd MA mark, and user equipment receives After MBMS synchronization signal, the 2nd MA mark can be obtained.The MA of 2nd MA mark instruction is the 2nd MA.It is assisted in current standard In view, in order to distinguish different MA, different MA have different marks, which is known as MA mark (MBSFN area identity).MA mark cannot be supplied to user equipment by synchronization signal, but be carried on system message (system Information in), user equipment needs first to synchronize, then receives system message, then obtains MA mark.It, should in different MA MA mark is for scrambling MBMS data, and user equipment, which is based on MA mark, can carry out descrambling operation, to obtain MBMS industry Business data.Therefore, when which is that the 2nd MA is identified, for the cell in the 2nd MA, such as second community, for, Transmission the 2nd MA mark is no longer needed in system message, can save resource overhead.For first community, need to consider first community With the attaching relation of the 2nd MA.

In general, which is not belonging to the 2nd MA.At this point, first community belongs to the first MA, first can be obtained MA mark.In embodiments of the present invention, first community, which still needs to be identified according to the 2nd MA, generates and transmits MBMS synchronization signal, What the MBMS synchronization signal carried is the 2nd MA mark.At first sight, it does not appear to especially increase for first community itself Benefit.It is contemplated that is transmitted between difference MA is identical MBMS synchronization signal, for user equipment, avoid between different MA The interference that different synchronization signals generates is transmitted, especially when first community and second community (the first MA and the 2nd MA in other words) When adjacent, gain is still objective.

Certainly, first community can also belong to the 2nd MA, i.e. first community had both belonged to the first MA, also belong to the 2nd MA. The scene was had been contemplated that in the embodiment shown in fig. 3, in embodiments of the present invention, without configuring two sets of synchronizations in first community Channel.Theoretically, the first MA mark and the 2nd MA mark may be used to generate MBMS synchronization signal.But described first Cell belongs to the 2nd MA, and when the number of the 2nd MA cell that includes is than or equal to a MA；Alternatively, The 2nd MA is belonged in the first community, and the geographic area of second community covering is greater than or equal to described first When cell；Specified 2nd MA mark generates MBMS synchronization signal, can preferably improve covering, save resource overhead.This and back The thinking of the scheme referred in scape technology is different, in a way even it is considered that completely contradicting.In that scheme, for MA Overlay scenes, it is proposed that using the covering of multiple smaller MA, complete the covering of biggish MA.

Optionally, in a kind of optional embodiment, the radio reception device 500 further include: receiver 540；It is described Processor 530 obtains MBMS sync id for controlling the radio reception device 500, comprising: the processor 530 be used for The receiver 540 communicates, so that: the radio reception device 500 receives the configuration message that core network device is sent, described Configuring includes the MBMS sync id in message.

Optionally, in another optional embodiment, the radio reception device 500 further includes memory 550, described The code for being used to indicate the MBMS sync id is stored in memory 550；The processor 530 is described wireless for controlling Access device 500 obtains MBMS sync id, comprising: the processor 530 is used to read to be used to refer in the memory 550 Show the code of the MBMS sync id.

Optionally, on the basis of the embodiment of the present invention and each optional embodiment, above-mentioned radio reception device 500 can be with Include:

Memory 560 stores the code for being used to indicate the radio resource of the pre-configuration in the memory 560；With/ Or,

Receiver 570, for receiving the second configuration message of core network device transmission, the second configuration message is used for Initialize or update the radio resource of the pre-configuration.

Wherein, the memory 560 can be identical or different memory with memory 550；The receiver 570 with The receiver 540 can be identical or different receiver.For sake of simplicity, without 560 He of memory separately shown again in Fig. 5 Receiver 570.

In actual deployment, radio reception device 500 can be base station, be also possible to MBMS broadcasting equipment, the MBMS is wide Broadcasting equipment is the broadcasting equipment that deployment is used for MBMS transmission.Compared with base station, which can be understood as independent portion Administration, is exclusively used in the broadcasting equipment of MBMS transmission.It can only be used it should be understood that being exclusively used in MBMS transmission and being not limited to the MBMS broadcasting equipment In MBMS transmission, which obviously can also have other function, but support that MBMS transmission is its major function.Than Compared with for, base station is also used in support unicast transmission, and support unicast transmission, for base station other than supporting MBMS transmission For may be more important.

Above-mentioned optional embodiment is suitable for the situation that radio reception device 500 is base station and MBMS broadcasting equipment.When When radio reception device 500 is MBMS broadcasting equipment, since the MBMS broadcasting equipment is individually to dispose and be exclusively used in MBMS transmission Broadcasting equipment, in equipment factory, first installation or equipment debugging, can relatively easily the built-in memory 550 or 560, alternatively, being used to indicate by memory 550 or 560 copy of the external interface into the broadcasting equipment of MBMS transmission described The code of MBMS sync id.

It is described pre- by configuring message transmission MBMS sync id, initializing or updating in above-mentioned optional embodiment The radio resource of configuration, it is more flexible and convenient, but need to occupy certain Internet resources.Comparatively, it is appointed in advance by agreement Fixed or internal memory is pre-configured with MBMS sync id and radio resource, then can save certain Internet resources, but such as Fruit needs to change configuration, then relatively cumbersome.

It should be noted that the MBMS broadcasting equipment is especially suitable for the mobile TV scene based on MBMS technology.It is existing Radio and television operator or mobile communication carrier individually disposed using existing television spectrum as MBMS special carrier MBMS broadcasting equipment, dedicated for MBMS transmission, to provide a user the data clothes of the high-speeds such as mobile TV service Business.These MBMS broadcasting equipments can configure or integrate the capacity unit for supporting MBMS transmission, it is preferable that using powerful Radio frequency unit and antenna.Therefore, the coverage area of a MBMS broadcasting equipment can be far longer than a base in current LTE system The coverage area that station is capable of providing.In this way, the number of MBMS broadcasting equipment needed for one city of covering, is far less than and uses base The number stood.Certainly, MBMS broadcasting equipment can also be with base station mixed networking.For example, being responsible for mainly covering by MBMS broadcasting equipment Lid, the edge of MBMS broadcasting equipment overlay area are reconfigured base station and realize covering.For the hot spot region of MBMS business, such as learn School, shopping centre can also configure base station and be covered, and provide capacity enhancing.

Particularly, for the scene of MBMS broadcasting equipment and base station mixed networking, the communication that is provided in embodiment illustrated in fig. 4 In system 400, preferably the first radio reception device is base station, and the second radio reception device is MBMS broadcasting equipment.Also, consider To using under MBMS special carrier scene, the concept of cell may change in existing cellular communication system.In the application The concept of cell can further expand, to be suitable for MBMS broadcasting equipment.

By taking LTE as an example, it is to provide access service for user equipment that cell, which is the basic composition unit of Radio Access Network, Minimum service unit.Each cell has a proof of identification (identification), which is referred to as small Area identifies (Cell Identity).The cell ID is by the access device of Radio Access Network, such as base station, in certain geographic region It is broadcasted in domain.User equipment in the geographic area can be based on the cell ID unique identification cell, and accessing should Cell enjoys radio communication service.In general, cell is related to two layers of meaning, first is that the overlay area (coverage of cell Area), related to the geographic area of broadcast cell mark；Second is that the combination of resources of cell, the frequency with offer radio communication service Rate resource is related.Overlay area is related to the geographic area that broadcast cell identifies, but not exactly the same, is normally defined and reaches certain The geographic area of one service request.The combination of resources of cell is related to carrier wave (carrier) but not exactly the same.Carrier wave is usual It is defined as the data of carrying radio communication service or the modulated waveform of control signaling.One cell can have multiple loads Wave, a carrier wave can also be shared by multiple cells.

In this application, since radio reception device no longer broadcast cell identifies, broadcasting MBMS sync id, such as second MA mark.If future is directed to MBMS special carrier, cancel the concept of cell, then the cell in the application also is understood as indicating For the radio reception device, the covered geographic area of MBMS special carrier broadcast singal institute is used.It is specific to consider MBMS Transmission still can be unit by MA, carry out MBSFN transmission for MBMS business.Cell in different MA, uses difference MA mark MBMS data is scrambled.For MBMS synchronization signal, can more MA cooperation transmissions, further ensure and cover Lid reduces resource overhead.MA mark is similar to original cell ID concept at this time, but difference is that user equipment parses To MA mark be not necessarily for scramble MBMS data MA mark.User equipment can also be disappeared by other system Breath or MBMS control information, obtain others MA mark.
