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 method of support multimedia broadcast multi-broadcasting business transmission, equipment and system.

Background technique

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

As smart phone and the quick of tablet computer are popularized, user is growing day by day for the demand of the data services such as mobile video business, application program downloading, and the data traffic of the network carrying also sharply rises.At this point, a large amount of unicast bearer will occupy a large amount of Internet resources if continuing to use unicast bearer mode, it is 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) comes into being.MBMS is carried by establishing the multicast of single point-to-multipoint, can provide identical content to multiple users simultaneously.Therefore, the scene concentrated especially suitable for user interest degree, such as: important sports events live streaming, customization video push, application program update.

Fig. 1 is the deployment schematic diagram of mobile communications network in the prior art, including one or more base stations.Each BTS management one or more cell (cell), in Fig. 1 by taking one cell of a BTS management as an example.Several user equipmenies are distributed in each cell, these user equipmenies and base station can by eat dishes without rice or wine (air interface) connect, communication service can be enjoyed after accessing cell.By taking sports show as an example, it is assumed that multiple user equipmenies request sports show service simultaneously.As shown in the upper left side of Fig. 1, base station can The video content of sports show is transmitted to multiple user equipmenies (UE 1, UE 2, UE 3) respectively by multiple point-to-point unicast bearers.Since different unicast bearers can occupy different Internet resources, if the number of user equipment is excessive or Internet resources are limited, it is easy to appear video cardton or interrupts situation, influence the business experience of user.As shown in the lower left Fig. 1, base station can also be carried by the multicast of a single point-to-multipoint, while transmit identical video content to multiple user equipmenies (UE 1 ', UE 2 ', UE 3 ').Due to the Internet resources of the occupancy of multicast carrying, hardly change as user device quantity purpose increases.Therefore, the business experience of user can be effectively ensured, and the number of user equipment is more, the utilization rate of Internet resources is higher.

In long term evolution (long term evolution, abbreviation LTE) in 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, the identical data content of simultaneous transmission in multiple cells.As shown in Figure 1, cell 1, cell 2 and cell 3 can use identical radio-resource-configuration, 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), when receiving video content, the signal from multiple cells effectively overcomes the interference of minizone such as the multipath signal from a cell.Therefore, the gain of MBSFN transmission includes the interference of the minizone of merging gain and the reduction of receiver, to further improve 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, and in addition to being explicitly emphasized that, the application does not distinguish the two.The concept of the synchronization zone MBSFN (MBSFN synchronization area) and the region MBSFN (MBSFN area, referred to as: MA) is defined in order to support MBSFN to transmit, in LTE.Base station in the synchronization zone MBSFN 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 the synchronization zone MBSFN.MBSFN is transmitted as unit of MA, and MA is made of some cells in the synchronization zone MBSFN, and all cell cooperatives for belonging to the MA complete MBSFN transmission.For example, the cell 1, cell 2 and cell 3 in Fig. 1 can form a MA.One MBSFN Synchronization zone may include one or more MA, can be overlapped between multiple MA, and a cell can belong to multiple MA simultaneously.

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 and MA 2 partly overlap, and 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.The cell for participating in MBMS transmission configures radio resource using time division multiplexing mode, can both support MBMS transmission on the same carrier wave, can also support unicast transmission.Such cell is referred to as the Unicast-mixed cell MBMS/ (MBMS/Unicast-mixed cell).User 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 is sent as unit of cell, and the cell ID (cell identity, referred to as: Cell ID or CI) of the cell is carried in synchronization signal.Different cells sends different synchronization signals, and different synchronization signals carries different cell IDs.User equipment is synchronized by detecting the synchronizing channel of cell, and determines unique cell ID, and then receive broadcast message.That is synchronizing channel and broadcast channel is still as unit of cell, and the Multicast Channel of carrying MBMS data and control information is as unit of MA.

In addition, in the LTE standard discussion of early stage, it is also considered that realize that MBMS transmission, cell can carry out MBMS transmission exclusively with a carrier wave in the form of special carrier, 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, the concrete scheme in LTE standard about the dedicated cell MBMS is all come to nothing.For example, the transmission process of the synchronizing process of MBMS cell, MBMS data and related control information, is still blank out in a standard.

In the prior art, it is also discussed about the synchronization scheme of MBMS special carrier.For example, increasing MBMS special carrier in the cell by means of the existing down-going synchronous scheme of cell, and the existing carrier wave that the MBMS special carrier and the cell is arranged keeps down-going synchronous.User equipment and the cell are same After step, it can be realized synchronous with MBMS special carrier.But this scheme has more limitation in actual deployment, it is desirable that the range of MBMS special carrier, less than or equal to the coverage area of existing cell.

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 original cellular concept needs to discuss again at this time, and the method that synchronizing channel and broadcast channel are configured as unit of cell is no longer applicable in.Alternatively, program suggestion configures synchronizing channel and broadcast channel as unit of MA.In other words, the identical synchronization signal of transmission, the synchronization signal carry the unique identification of the MA, different synchronization signals are transmitted between different MA in identical MA.The case where for MA overlapping, a such as biggish MA is made of multiple lesser MA, the covering of this biggish MA is completed by the combination of the covering of these lesser MA.This biggish MA itself no longer needs to that synchronizing channel or broadcast channel is separately configured.If user equipment needs to access this biggish MA, 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 the covering of this larger MA 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 is contemplated that worst case.Covering requirement for broadcast channel, program suggestion and the covering of the Unicast-mixed cell MBMS/ require identical.Therefore, in actual deployment, the program is more demanding for the covering of network.On the other hand, the case where program partly overlaps for MA 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 made of other multiple MA, if simply continuing to use the program, synchronizing channel only is configured in MA 1 and MA 3, then the covering of MA 2 will appear loophole.In order to avoid such case, it may be necessary to plan the configuration of MA in advance, this will also result in certain restrictions in actual deployment.

Using the technical solution of the offer of for example above-mentioned various aspects introduction of the embodiment of the present invention, it is more convenient in actual deployment compared with existing MBSFN transmission, the identical MBMS synchronization signal of more MA cooperation transmissions may be implemented, the coverage area of synchronization signal can either be promoted, transfer resource can be also saved.In some alternative embodiments, when MBMS is identified as the 2nd MA mark, transmission the 2nd MA mark is no longer needed to for the cell in the 2nd MA, in system message, can further save resource overhead.In other optional embodiments, by configuring message transmission MBMS sync id, the radio resource of the pre-configuration is initialized or updates, it is more flexible and convenient, but need to occupy certain Internet resources.Comparatively, it in some other optional embodiment, is made an appointment by agreement or internal memory is pre-configured with MBMS sync id and radio resource, then can save certain Internet resources, but if necessary to change configuration, then it is relatively cumbersome.

In addition, be directed to special carrier MBMS, in 3GPP agreement also it is not clear how configuration of the notifying user equipment about special carrier MBMS.In view of this, present invention further contemplates that passing through Master Information Block (Master Information Block, referred to as: MIB) and system information block (System Information Block, referred to as: SIB) transmits the configuration of MBMS, and provides the following technical solutions:

9th aspect, additionally provides a kind of method for supporting multimedia broadcast multi-broadcasting business (MBMS) to transmit, and this method can be adapted for the interaction between radio reception device and user equipment.For radio reception device angle, comprising: radio reception device generates Master Information Block MIB, and the radio reception device broadcasts the MIB.For user equipment angle, comprising: user equipment carries out down-going synchronous, and receives the MIB of radio reception device broadcast.

Wherein, the MIB includes at least one of following information: the configuration instruction information of system information block SIB, and the change of SIB indicates information, the change instruction of MBMS Control Channel (MCCH) Information, the SIB includes to be used to indicate MBMS Single Frequency Network (MBSFN) region (MBSFN area, the information of configuration referred to as: MA), the configuration instruction information of the SIB is used to indicate the configuration of SIB, the change instruction information of the SIB is used to indicate whether SIB changes, and the change instruction information of the MCCH is used to indicate whether MCCH changes.Whether SIB changes, and may include whether the content of SIB carrying changes, also may include whether the configuration of SIB changes.Similarly, whether MCCH changes, and may include whether the content of MCCH changes, and also may include whether the configuration of MCCH changes.

For example, can only include the configuration instruction information of SIB in the MIB；Alternatively, can simultaneously include the configuration instruction information of SIB, the change of SIB indicates information；Alternatively, can also simultaneously include the configuration instruction information of SIB, the change instruction information of SIB and the change of MCCH indicate information.

It in realization, can be used whether 1bit instruction SIB changes, can be used whether 1bit instruction MCCH changes.For example, the bit sets 1, otherwise sets 0 if SIB changes.If UE receives the instruction of SIB information change, new SIB information is received again.If MCCH changes, which sets 1, and otherwise the bit sets 0.If MCCH changes, UE needs to receive MCCH again.

As a kind of optional implementation, the change of SIB indicates information, and/or, changes of MCCH indicate information can also the configuration instruction information than SIB be more preferentially carried in MIB." preferential " herein can relate to whether to carry, and also relate to the successive of carrying position.The former is for example, the change instruction information for carrying SIB in MIB when MIB capacity is limited or considers based on other, may not need the configuration instruction information of carrying SIB if a cycle does not change earlier above for the configuration of SIB.For the latter for example, after UE reception MIB, first parsing obtains the change instruction information of SIB, and rear parsing obtains the configuration instruction information of SIB.

For user equipment (UE), after UE receives MIB, by the configuration instruction information of wherein SIB, the configuration of SIB can be determined, and then receive SIB, and the configuration information about MA carried in SIB is obtained, to smoothly complete subsequent MBMS transmission；Information is indicated by the change of the SIB in MIB, and UE can determine whether SIB changes；Information is indicated by the change of the MCCH in MIB, and UE can determine whether MCCH changes.Match with the scheme in the last period It closes, if UE indicates that information determines that SIB does not change by the change of SIB, since MIB and SIB can be configured to periodicity sending, UE may not need the configuration instruction information for continuing to parse SIB, or even without receiving SIB, to save the computing cost of UE, power consumption can also be saved.

In the prior art, for mixed carrier MBMS, the MIB message of base station broadcast usually only includes system bandwidth and System Frame Number information.It about the configuration information of SIB, is then transmitted by Physical Downlink Control Channel (PDCCH), these PDCCH occupy certain transfer resource, preceding several symbols of usually one subframe.Comparatively, can then transmit the configuration information of SIB by MIB in the technical solution that the 9th aspect as above and possible implementation provide.There is a small amount of reserved bit not yet to use since MIB is difficult to replace, and in current MIB.Therefore, using the technical solution, for MBMS transmission, especially special carrier MBMS transmission, it may not need design or occupy PDCCH, save certain transfer resource.

In conjunction with the 9th aspect, in one possible implementation, the radio reception device broadcasts the MIB, comprising: the radio reception device scrambles the MIB using MA mark, and broadcasts and identify scrambled MIB through the MA.Correspondingly, user equipment utilizes identical MA mark descrambling MIB (identifying scrambled MIB through the MA).

In conjunction with the 9th aspect or its any possible implementation, in alternatively possible implementation, further includes: the radio reception device scrambles the SIB using MA mark, and broadcasts and identify scrambled SIB through the MA.Correspondingly, user equipment utilizes identical MA mark descrambling SIB (identifying scrambled SIB through the MA).

In general, in mobile communication system, after user equipment needs to complete down-going synchronous, MIB and SIB could be received.

In one possible implementation, user equipment receives the MBMS synchronization signal of radio reception device broadcast, and to obtain MBMS sync id, which can be the mark of MBMS single frequency network area MA.

About synchronizing process and its related notion (such as MBMS sync id or MA mark), wirelessly The behavior of access device, the implicit or behavior of user equipment that is expressly recited, can form more perfect technical solution in conjunction with aforementioned aspects and its possible implementation.As an example, the MBMS synchronization signal of the user equipment reception radio reception device broadcast may include: to obtain the mark of MA

The user equipment monitors MBMS synchronizing channel, and detects MBMS synchronization signal based on serial correlation, to determine that the MBMS sync id for generating the MBMS synchronization signal, the MBMS sync id are MA mark；Wherein, indicate that the information of the sequence used in the information of the MBMS synchronizing channel, and the instruction serial correlation detection is stored in advance in the user equipment.

In realization, the sequence used in the MBMS synchronizing channel and serial correlation detection can be arranged by communication standard protocol.

MBMS sync id or MA mark can be the ZC sequence in LTE, and the process for obtaining MBMS sync id or MA mark can be with reference to the process for obtaining cell ID in LTE.Such as user equipment makees related operation with reception signal respectively using one group of local ZC sequence, when the correlation of certain ZC sequences meets synchronous condition (such as correlation is more than threshold value), down-going synchronous can be realized, and determine that MBMS sync id or MA identify based on these ZC sequences.

In above two possible implementation, the MA for scrambling MIB and for scrambling SIB is identified, and may be the same or different.The radio reception device is used to scramble the MA mark of MIB and/or SIB, can obtain with reference to any case in above-mentioned first aspect, fourth aspect and the 5th aspect and its various possible implementations.Certainly, if identified without using MA, radio reception device can also be used the MBMS sync id in aforementioned any case to be scrambled, these MBMS sync ids can be used for multiple radio reception devices, especially adjacent radio reception device simultaneously.Correspondingly, user equipment is descrambled using identical MBMS sync id.

For example, the radio reception device receives the configuration message that core network device is sent in a kind of possible realization, identified in the configuration message comprising the MA.Optionally, further includes: institute It states radio reception device to be identified according to the MA, generates simultaneously broadcasting MBMS synchronization signal.

As a kind of realization, the radio reception device can be eNB, core network device can be MCE, the two passes through M2 interface communication, the configuration message can be M2 and establish response (M2setup response), and eNB configuration updates confirmation (ENB configuration update acknowledge).

Optionally, in addition, the indicated MA of the MA mark is one in whole MA of radio reception device participation, also includes in the configuration message: being used to indicate the radio reception device and identify the information for generating MBMS synchronization signal according to the MA；Alternatively, MA indicated by the MA mark is the MA except whole MA that the radio reception device participates in.

It in the prior art, for mixed carrier MBMS, MIB and SIB is sent according to cell granularity.The cell ID (cell ID) of the MIB and SIB information of each cell cell scrambles, therefore for the UE of some cell of access, when receiving the MIB of current area, the mib information of other cells is exactly to interfere, the signal and interference-to-noise ratio that will lead to UE in this way reduce, and receptivity is poor.

Comparatively, in above-mentioned possible implementation of the invention, it is contemplated that in a region MBSFN, the content for the MIB and SIB information that each cell is sent is actually identical.Therefore, radio reception device scrambles MIB and/or SIB using MA mark (or MBMS sync id), to send identical MIB and/or SIB.For UE, MIB and SIB that multiple radio reception devices are sent can be merged, to promote received signal quality.

When radio reception device participates in the multiple region MBSFN (MA), each MA can have different configurations, be used for transmission different contents.Configuration for notifying user equipment about these MA, it may be considered that the following two kinds implementation: a SIB is used to indicate the configuration of a MA；Alternatively, a SIB is used to indicate the configuration of multiple MA, wherein multiple MA can be the whole MA or part MA of radio reception device participation.

The multiple MA of above-mentioned radio reception device " participation ", it can be understood as refer to radio reception device " be located at/it is present/ ", " belonging " or " support " multiple MA.Its concrete meaning can both continue to use existing cellular concept, refer to that one or more cells of radio reception device management belong to Multiple regions MBSFN；Alternatively, existing cellular concept can also be replaced with the concept of MA, at this point, referring to that radio reception device itself participates in multiple MA.

In conjunction with the 9th aspect or its any possible implementation, in one possible implementation, it include the configuration instruction information of SIB in the MIB, one SIB is used to indicate the configuration of a MA, the configuration instruction information of the SIB includes: to indicate the information of SIB number, or indicate the information of the number for the MA that the radio reception device participates in.In the implementation, the size of each SIB can be fixed, and radio reception device participates in several MA, just send several SIB, and the number of SIB or MA is accordingly indicated in MIB.

In conjunction with the 9th aspect or its any possible implementation, in alternatively possible implementation, it include the configuration instruction information of SIB in the MIB, one SIB is used to indicate the configuration of at least two MA, the configuration instruction information of the SIB includes: the information of the number for the MA for indicating the information of the size of the SIB, or include in the instruction SIB；It wherein, is whole MA of radio reception device participation by least two MA that the SIB is indicated.In the implementation, the number for the MA for including in the size and SIB of SIB can be corresponded, and MA number is more, and the size of corresponding SIB is also bigger.

In conjunction with the 9th aspect or its any possible implementation, in other possible implementations, the other configurations of the SIB include one of following information or a variety of: indicating the information of the modulation coding scheme of the SIB, it indicates the information of the transfer resource position of the SIB, and indicates the information of the transmission mode of the SIB.

Wherein, the other configurations of above-mentioned SIB can be defaulted as fixed configurations, or mutually manage with MIB configuration, to reduce the transport overhead for the configuration for being used to indicate SIB in MIB.Alternatively, increasing one of above- mentioned information or a variety of, in MIB to improve the flexibility of SIB configuration.Again alternatively, storing the corresponding relationship of the configuration instruction information of above-mentioned SIB and the other configurations of above-mentioned SIB simultaneously in radio reception device and user equipment still can provide certain flexibility while saving transport overhead.The corresponding relationship can be determined based on communication standard protocol, or negotiate to determine by other means.

For example, the corresponding relationship can be one or more predefined tables, SIB's matches in table The other configurations for setting instruction information and above-mentioned SIB correspond, and user equipment can confirm the other configurations of SIB by tabling look-up according to the configuration instruction information of the SIB received.

Assuming that the number for the MA that radio reception device participates in is 8, then it can use the information of 3bit to indicate the configuration instruction information of SIB, the corresponding 8 kinds of situations of the 3bit.The value of the 3bit information can indicate SIB number, the number for the MA that radio reception device participates in, the number for the MA for including in the size or SIB of SIB.

1bit or more instruction can be used in the modulation coding scheme (MCS) of SIB.In order to reduce the bit number of needs, the MCS that SIB can be used can be limited.If 2 kinds of possible MCS can only be used by limiting SIB, only needs 1bit to indicate, more bit is otherwise needed to indicate.If it is considered that reducing expense, the MCS of SIB can also be fixed.

The transfer resource of SIB may include frequency domain resource and time-domain resource.For example, being directed to frequency domain resource, can be usedOrBit indicates the RB number and position that SIB information occupies；WhereinFloor operation in expression,Indicate the total available RB resource number of downlink, the value of P is related to bandwidth, and specific implementation can be consistent with present LTE protocol.UE receives SIB information according to the position that the information indicates.For time-domain resource, the radio frame number and subframe numbers that SIB is sent can be specifically indicated.For example, subframe numbers can use bitmap form or specific value (value for 0~9) to indicate.

The transmission mode of SIB may include single antenna transmission or 2 antennas, 4 antenna transmitting diversities.The MIB and above-mentioned corresponding relationship that UE can be received determine SIB transmission mode.Or it may also require that the transmission mode of SIB information is identical with MIB.

The specific implementation of the other configurations of above-mentioned SIB can default first, radio reception device and user equipment reached an agreement by interacting.Radio reception device determines that matching for SIB postpones using one way in which, sends the SIB, user equipment also adopts the configuration for determining SIB in a like fashion, and receives the SIB according to identified configuration.

In conjunction with the 9th aspect or its any possible implementation, in other possible implementations, the radio reception device broadcasts the MIB, may include:

The radio reception device continues to use the broadcast cycle for the MIB that Current standards define, i.e., with 4 radio frames (40ms) for broadcast cycle.For example, on Physical Broadcast Channel (PBCH), first subframe of every continuous 4 radio frames periodically transmits MIB.

Similarly, in conjunction with the 9th aspect or its any possible implementation, in other possible implementations, the radio reception device broadcasts the SIB, may include:

The radio reception device continues to use the broadcast cycle for the SIB that Current standards define, i.e., with 8 radio frames (80ms) for broadcast cycle.For example, on Physical Broadcast Channel (PBCH), first subframe of every continuous 8 radio frames periodically transmits MIB.Optionally, the radio reception device can also broadcast cycle by the MCCH repetition period (MCCH repetition period) as SIB.

Optionally, the radio reception device can also broadcast cycle by the MCCH repetition period (MCCH repetition period) as MIB and/or SIB.

In the specific implementation, the broadcast cycle of MIB or SIB can be arranged by communication standard protocol, UE is based on the broadcast cycle, receives MIB or SIB.

For example, first sub-frame transmission MIB of the radio reception device in the last one or multiple (such as 2, the 4 etc.) radio frames of MCCH repetition period.The MIB can be through MA mark or the scrambled MIB of MBMS sync id.In specific transmission, if in the MCCH repetition period, certain subframes or symbol have been used for transmitting MCCH or multicast transmission channel (multicast channel, MCH) scheduling information (MCH scheduling period, the contents such as MSI), then MIB or SIB, which is generally required, avoids these positions.

Since MCCH repetition period general minimum 32 radio frames can save the resource overhead of transmission MIB using the lower repetition period.In addition, UE can also determine the MCCH repetition period, therefore system need not can also separately expend the resource notification UE MCCH repetition period by the broadcast cycle of detection MIB or SIB indirectly.

Fig. 3 is a kind of network architecture schematic diagram for supporting MBMS transmission suitable for the embodiment of the present invention.As shown in figure 3, the network architecture 300 includes user equipment (301,302), access network device (311,312,313) and core network device (320,330,340).It should be understood that above equipment is enumerated merely for illustrative purpose in Fig. 3, in actual deployment, however it is not limited to which Fig. 3 form, the type and number of above equipment can be increased or decreased adaptively, for example, increasing other indispensable core network devices.For the basic concepts of MBMS transmission involved in the present invention, such as MBSFN, MA, MA mark, synchronizing process, scrambling, some background knowledges that descrambling etc. and the present invention realize, can be with reference to the relevant regulations in current LTE protocol, such as: 3GPP TS 36.300,36.321,36.331,36.211, the introduction of 36.213,36.443,36.444 equal related Sections.

Hereinafter, the application will introduce each embodiment of the invention by taking LTE system as an example.

In LTE system, these access network devices are base station, specially eNB.Core network device 320 is MME, core network device 330 is multiple cell/multicast coordination entity (multi-cell/multicast coordination entity, referred to as: MCE), core network device 340 is MBMS gateway (referred to as: MBMS-GW).Convenient for statement, multiple cell/multicast coordination entity is referred to as multicast coordination entity or MCE in the application.It should be noted that MCE is logic entity, in actual deployment, it can be used as an independent equipment and exist, can also merge with other equipment and dispose, such as be integrated into base station or other core network devices.

In order to support MBMS transmission, especially MBSFN transmission, the function of MCE specifically includes that reception and transmits MBMS session control signaling (session control signalling) to eNB, support conversation management functional (such as session initiation, session stopping etc.), it is responsible for the radio resource of scheduling eNB management cell, guarantees the consistency of the radio-resource-configuration of each cell in single MA.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 sends MBMS data by way of IP multicast, to eNB.Interface between MCE and eNB is known as M2 interface, is control plane interface, transmits M2 interface signaling based on Flow Control Transmission Protocol (stream control transmission protocol, SCTP), it then follows M2 Interface protocol regulation.The interface of MCE and MME is known as M3 interface, is control plane interface, transmits M3 interface signaling based on SCTP, 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, the cell that base station 311 manages 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 MA2, the embodiment of the present invention be can be considered for MA2, in addition configure synchronizing channel, to guarantee the covering of MA2.For the cell that base station 312 manages, 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 staggered transmission by base station 312, but this will cause certain wasting of resources, for the UE in MA marginal position, may be subjected to more interference of adjacent MA.Also, when partly overlapping there are multiple MA, the program will be more complicated, possible and less than optimal 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 includes the first radio reception device and the second radio reception device.Wherein, the first radio reception device manages first community, and the 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 the 2nd MA, and the first MA is different from the 2nd MA.

Specifically, first radio reception device is used for: obtaining the first MBMS sync id；The first MBMS synchronization signal is generated according to the first MBMS sync id；The first radio resource based on pre-configuration broadcasts the first MBMS synchronization signal.

Second radio reception device is used for: obtaining the 2nd MBMS sync id；The 2nd MBMS synchronization signal is generated according to the 2nd MBMS sync id；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, the second radio resource of the first radio resource of the pre-configuration and the pre-configuration is identical radio resource.

Optionally, communication system 400 further include: the core network device connecting respectively with first radio reception device, second radio reception device 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 broadcast identical MBMS synchronization signal on identical radio resource.For user equipment, belong to the MBMS synchronization signal transmitted in the different community of different MA, be equivalent to the synchronization signal from the same cell, reception can either be obtained and merge gain, it can also be to avoid the interference for transmitting different synchronization signal generations between different MA.Therefore, compared with existing MBSFN transmission, the technical solution in the embodiment of the present invention is more convenient in actual deployment, and the identical MBMS synchronization signal of more MA cooperation transmissions may be implemented, can either promote the coverage area of synchronization signal, 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 is 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 can be the first radio reception device or the second radio reception device in communication system 400 shown in Fig. 4.The radio reception device 500 manages first community, and 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.Wherein, which may include: wireless interface and wireline interface.Wherein, wireless interface can refer to antenna, may also mean that 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 and data to processor 530.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 Communication interface 510 is may be coupled to receiver 540.The various components of radio reception device 500 are coupled by bus system 50, and wherein bus system 50 can also include power bus, control bus and status signal bus in addition etc. in addition to including data/address 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 processor 530 being connect with the transmitter.The processor 530 is for controlling the radio reception device 500: obtaining MBMS sync id；MBMS synchronization signal is generated according to the MBMS sync id；And the radio resource based on pre-configuration, broadcast the MBMS synchronization signal.Wherein, the MBMS sync id, the radio resource of the pre-configuration are also applied for second community, and the second community belongs to the 2nd MA, and the first MA is different from the 2nd MA.

The second community can be by other radio reception device management except radio reception device 500.When not considering the compatibility with 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 number of MBMS synchronization signal, sequence type, sequence length and sequence value and MBMS sync id and MBMS synchronization signal corresponding relationship, can be arranged by communication protocol.It, can be according to the MBMS sync id, a uniquely generated MBMS synchronization signal after radio reception device receives a MBMS sync id.Similarly, the radio resource of the pre-configuration can also be arranged by the communication protocol.It is understood that, at least one of the MBMS synchronization signal of communication protocol agreement and radio resource, with the synchronization signal and radio resource for being used for unicast transmission in current LTE communication system, it should different from, so that user equipment is in the case where no prior information, it can know that current communication networks support MBMS transmission.

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

Optionally, in a kind of optional embodiment, which is the 2nd MA mark, after user equipment receives MBMS synchronization signal, can be obtained the 2nd MA mark.The MA of 2nd MA mark instruction is the 2nd MA.In current standard agreement, 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 in system message (system information), and user equipment needs first to synchronize, then receives system message, then obtain MA mark.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 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 the attaching relation of first community Yu the 2nd MA.

In general, which is not belonging to the 2nd MA.At this point, first community belongs to the first MA, the first MA mark can be obtained.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, and what which carried is the 2nd MA mark.At first sight, special gain is not appeared to for first community itself.It is contemplated that is transmitted between difference MA is identical MBMS synchronization signal, for user equipment, it avoids transmitting the interference that different synchronization signals generates between different MA, especially when first community and adjacent second community (the first MA and the 2nd MA in other words), 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 synchronizing channels in first community.Theoretically, the first MA mark and second MA mark may be used to generate MBMS synchronization signal.But the 2nd MA is belonged in the first community, and when the number of the 2nd MA cell that includes is than or equal to a MA；Alternatively, belong to the 2nd MA in the first community, and when the geographic area of second community covering is greater than or equal to the first community；Specified 2nd MA mark generates MBMS synchronization signal, can preferably improve covering, save resource overhead.This is different from the thinking of the scheme referred in background technique, 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；The processor 530 obtains MBMS sync id for controlling the radio reception device 500, it include: the processor 530 for being communicated with the receiver 540, so that: the radio reception device 500 receives the configuration message that core network device is sent, and includes the MBMS sync id in the configuration message.

Optionally, in another optional embodiment, the radio reception device 500 further includes memory 550, stores the code for being used to indicate the MBMS sync id in the memory 550；The processor 530 obtains MBMS sync id for controlling the radio reception device 500, comprising: the processor 530 is used to read the code for being used to indicate the MBMS sync id in the memory 550.

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

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

Receiver 570, for receiving the second configuration message of core network device transmission, the second configuration message is used to 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 can be identical or different receiver with the receiver 540.For sake of simplicity, without memory 560 separately shown again and receiver 570 in Fig. 5.

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

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

In above-mentioned optional embodiment, by configuring message transmission MBMS sync id, the radio resource of the pre-configuration is initialized or updates, it is more flexible and convenient, but need to occupy certain Internet resources.Comparatively, it is made an appointment by agreement or internal memory is pre-configured with MBMS sync id and radio resource, then can save certain Internet resources, but if necessary to change configuration, then it is relatively cumbersome.

It should be noted that the MBMS broadcasting equipment is especially suitable for the mobile TV scene based on MBMS technology.Existing radio and television operator or mobile communication carrier dispose MBMS broadcasting equipment, individually using existing television spectrum as MBMS special carrier dedicated for MBMS Transmission, to provide a user the data service of the high-speeds such as mobile TV service.These MBMS broadcasting equipments can configure or integrate the capacity unit for supporting MBMS transmission, it is preferable that use powerful radio frequency unit and antenna.Therefore, the coverage area of a MBMS broadcasting equipment can be far longer than the coverage area that a base station is capable of providing in current LTE system.In this way, the number of MBMS broadcasting equipment needed for one city of covering, far less than the number for using base station.Certainly, MBMS broadcasting equipment can also be with base station mixed networking.For example, being responsible for main covering by MBMS broadcasting equipment, the edge of MBMS broadcasting equipment overlay area is reconfigured base station and realizes covering.For the hot spot region of MBMS business, such as 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, in the communication system 400 that provides in embodiment illustrated in fig. 4, preferably the first radio reception device is base station, and the second radio reception device is MBMS broadcasting equipment.Also, in view of using under MBMS special carrier scene, the concept of cell may change in existing cellular communication system.The concept of cell in the application can further expand, to be suitable for MBMS broadcasting equipment.

By taking LTE as an example, cell is the basic composition unit of Radio Access Network, is that the minimum service unit of access service is provided for user equipment.Each cell has a proof of identification (identification), which is referred to as cell ID (Cell Identity).The cell ID is broadcasted in certain geographic area by the access device of Radio Access Network, such as base station.User equipment in the geographic area can be based on the cell ID unique identification cell, and accesses the cell, enjoys radio communication service.In general, cell is related to two layers of meaning, first is that the overlay area (coverage area) of cell, related to the geographic area of broadcast cell mark；Second is that the combination of resources of cell, related to the frequency resource of radio communication service is provided.Overlay area is related to the geographic area that broadcast cell identifies, but not exactly the same, is normally defined the geographic area for reaching a certain service request.The combination of resources of cell is related to carrier wave (carrier) but not exactly the same.Carrier wave is normally defined the data of carrying radio communication service or the modulated waveform of control signaling.One cell can have multiple carrier waves, and 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 the 2nd MA are identified.If future is directed to MBMS special carrier, cancel the concept of cell, then the cell in the application also is understood as indicating using the covered geographic area of MBMS special carrier broadcast singal institute for the radio reception device.It is specific to consider MBMS transmission, for MBMS business, it still can be unit by MA, carry out MBSFN transmission.Cell in different MA scrambles MBMS data using different MA marks.For MBMS synchronization signal, can more MA cooperation transmissions, further ensure covering, reduce resource overhead.MA mark is similar to original cell ID concept at this time, but difference is, the MA mark that user equipment parses is not necessarily the MA mark for scrambling MBMS data.User equipment can also control information by other system message or MBMS, obtain others MA mark.
