The embodiment of the present invention provides a kind of broadcast system, as shown in Fig. 2-1, comprises, MBMS-GW, MCE, access point (accesspoint, AP) and access controller (accesscontroller, AC); MCE receives the conversation message that MME sends, and determines the AC that will receive conversation message, can be communicated between MCE and AC by M2 interface according to the area identification in this conversation message; AC receives the conversation message that MCE sends, and determines the AP that will receive session, can be communicated between AC and AP by CAPWAP agreement or proprietary protocol interface according to conversation message; After AP receives the conversation message of AC transmission, the connection between foundation and MBMS-GW, and receive multicast packet from MBMS-GW, can be communicated by M1 interface between AP and MBMS-GW; After AP receives multicast packet, eat dishes without rice or wine to broadcast at WIFI.Wherein M1 interface, M2 interface can follow existing 3GPP agreement.

The broadcast system that the embodiment of the present invention provides specifically can realize flow process as shown in Figure 3:

As shown at 301 in fig. 3, MCE receives the conversation message that MME sends, such as sessionstartrequest, in this conversation message, carrier area mark is (if carry multiple area identification in conversation message, can zone list form performance), MCE determines the AC that will receive conversation message according to the area identification that this receives, and sends conversation message to these AC determined.Be understandable that, MCE can intercom with multiple AC phase, is described in figure for an AC.

The area identification that above-mentioned MCE receives can be used for mark eMBMS service area.EMBMS service area refers to the geographical coverage area that eMBMS business sends, if the geographical coverage area that multiple eMBMS business sends is identical, then these eMBMS business can use identical area identification.EMBMS service area can be a region with common trait, such as: International Horticultural Expo Garden, and megastore, airport etc.An eMBMS business can be sent to multiple eMBMS service area.Network O&M personnel can divide multiple area identification for the whole network community, draw a circle to approve multiple area identification and form an eMBMS service area.

In 301, MCE determines the AC that will receive conversation message according to the area identification received, and can have multiple implementation, and wherein, the first implementation comprises:

MCE according to the area identification carried from the conversation message that MME sends received, the mapping table of inquiry business region and AC, the set in the region that service area can identify for area identification, thus determine the AC that will receive session.Concrete, such as, the area identification carried in the conversation message that MCE sends according to MME, knows the service area that this area identification identifies, and based on known service area, according to the corresponding relation of service area and AC, and then determines the AC that needs to receive session.Wherein the mapping table of service area and AC is a kind of form of expression of corresponding relation between service area and AC, also can be other forms, and this sentences mapping table is that example illustrates.

The mapping table of above-mentioned service area and AC can be kept in MCE; Also other positions in a network can be preserved, when needing, MCE can obtain the mapping table of this service area and AC by signaling message, or MCE is by the mapping table inquiry of signaling message to this service area and AC of preserving other positions in a network.The mapping table of this service area and AC can generate in the following way, such as, as shown in Fig. 3 3012: MCE according to AP can service area list, and the attaching relation of AP and AC, generates the mapping table of service area and AC.

Optionally, MCE can also according to the corresponding relation of AC and SCTP link, AP can service area list, and the attaching relation of AP and AC, generates the mapping table of service area and AC.

MCE can realize the attaching relation obtaining AP and AC in the following way:

As shown in Fig. 3 3011, after AC starts, connect with MCE, such as AC and MCE can set up SCTP (StreamControlTransmissionProtocol, SCTP) connect, after AC and MCE connects, AC passes through message, such as setuprequest message, the AP list reporting AC to manage, MCE, according to the AP list of the AC management of carrying in AC reporting message, generates the attaching relation table of AP and AC, this sentence attaching relation table be example to represent the relation between AP and AC, specific implementation form does not limit.

Optionally, AP can service area list, can be pre-configured in MCE, also can be that AC reports MCE, such as, the service area list that AC configures by setuprequest message, be reported MCE by AC.

In 301, MCE determines the AC that will receive conversation message according to the area identification received, and the second implementation comprises:

MCE receives the conversation message carrying area identification that MME sends, and determines the AC that will receive session, and then connects with these AC.

Specific implementation process is with reference to first kind of way, and difference is, in the second implementation, MCE first determines to receive the AC of session according to area identification after, the AC determined with these again goes to connect, and specific implementation process has a detailed description in first kind of way, repeats no more herein.

After MCE determines the AC that will receive conversation message, distribute conversation message to these AC determined.

If MCE is according to the mapping table of the area identification inquiry business region of carrying in the conversation message received from MME and AC, determine that inquiring service area has corresponding AC, then determine to distribute conversation message to these AC, concrete, MCE is by the AC distribution conversation message of M2 interface to this correspondence, optionally, MCE carries the AP list that AC distributes again in the conversation message distributed to AC;

As shown in Fig. 3 302, AC receives the conversation message of MCE distribution, determines the AP that will receive conversation message, and distributes conversation message to these AP;

Concrete, MCE sends sessionstartrequest message to the AC determined, the AP list that the AC carrying this message of reception in message manages, and AC determines the AP that will receive conversation message according to this AP list, and distributes conversation message to these AP determined.

Optionally, AC can according to MCE send conversation message in carry service area list query configuration AP can service area list, determine the AP that will receive session, and to these AP distribute conversation message.Concrete, such as, the service area information of carrying in the conversation message that AC sends according to MCE, determine the region needing to receive MBMS, the service area of the available AP understood according to AC side again, determine which AP is positioned at the region needing to receive MBMS, thus determine the AP needing reception session, and distribute conversation message to these AP.

As shown in Fig. 3 303, AP receives AC and distributes conversation message, according to the multicast address mark of carrying in conversation message, sets up the connection between described AP and MBMS-GW, and receives multicast packet from MBMS-GW;

Concrete, such as, after AP receives the conversation message of AC distribution, TMGI (the temporarymobilegroupidentity carried in recording conversation message, Temporary Mobile Group Identity) and user face Multicast IP Address corresponding relation, wherein TMGI is used for the mark that unique identification multicast and broadcast bearer serve in eMBMS, and adds multicast group according to the user face Multicast IP Address that session is carried, and is communicated between AP and MBMS-GW by M1 interface.AP receives multicast packet by M1 interface from MBMS-GW.AP can periodically at broadcast channel information of eating dishes without rice or wine, so that UE receives the channel information of AP broadcast.

Optionally, as shown in Fig. 2-2, can set up between AC and MBMS-GW and connect, specifically can be realized by M1 interface, the TMGI now carried in AC recording conversation message and user face Multicast IP Address corresponding relation, add M1 interface by user face Multicast IP Address.AC receives multicast packet by M1 interface from MBMS-GW, is then distributed to by the broadcast data received and specifies AP.

Further, after AP receives multicast packet from MBMS-GW, eat dishes without rice or wine to broadcast at WIFI after the multicast packet received is processed.

Concrete, after AP receives multicast packet, peel off GTPU and Sync head and obtain payload IP bag, and eat dishes without rice or wine to broadcast payload IP bag at WIFI; Record the corresponding relation of payload IP bag multicast address and TMGI, AP gathers the corresponding relation of all MBMSSession of this AP and broadcasts in the assigned ip multicast group of configuration simultaneously.

Embodiment two

The embodiment of the present invention provides another kind of multimedia broadcast multi-broadcasting business system, comprises, as shown in Figure 4, and MBMS-GW, MCE, and AP; Wherein, MCE determines to receive the AP of session and distributes conversation message to AP, is communicated between MCE and AP by M2 interface; AP receives multicast packet from MBMS-GW and is eating dishes without rice or wine to broadcast, and communicated by M1 interface between AP and MBMS-GW, wherein M1 interface, M2 interface follow 3GPP agreement.The broadcast system that the embodiment of the present invention provides specifically can realize method step as shown in Figure 5.

The difference of the broadcast system provided in the broadcast system that this embodiment provides and embodiment one is, only includes AP, and do not comprise AC in the present embodiment.The function of AC and AP in the function set of the AP in the present embodiment embodiment one.The process of specific implementation broadcast is as follows:

As shown in Fig. 5 501, MCE receives the conversation message that MME sends, carrier area mark in this conversation message, and MCE determines AP according to the area identification received, and sends conversation message to these AP determined;

The AP process that concrete MCE determines to receive session can determine the process of the AC that will receive session by MCE in reference example one;

As shown in Fig. 5 502, AP sets up the connection between the described AP that determines and described MBMS-GW according to the multicast address mark of carrying in conversation message, and receives multicast packet from described MBMS-GW;

Specific implementation process reference example one, repeats no more herein, and the AP in the present embodiment can realize the function of AC and AP in embodiment one.

By the broadcast system that above-described embodiment provides, UE can receive eMBMS business by WIFI.For the UE not supporting WIFI and LTE concurrent, namely UE can not support to receive eMBMS business by WIFI and receive eMBMS business by LTE network simultaneously; Although or UE supports that WIFI and LTE is concurrent, but when this UE enters LTE weak overlay area, UE can stop receiving eMBMS business by LTE network, then access WIFI receives eMBMS business, now, because embodiments provide a kind of WIFI broadcast system, UE can realize eMBMS business after entering WIFI overlay area, or UE is when entering WIFI overlay area from LTE overlay area, keep the continuity of eMBMS business.

Embodiment three

The embodiment of the present invention provides another kind of multimedia broadcast multi-broadcasting business system, comprises, as Fig. 6-1, Fig. 6-2, MBMS-GW, MCE, AC, AP and eNB; The embodiment of the present invention, on the basis of previous embodiment, adds base station (the present embodiment is described for eNB), and eMBMS business can be realized by base station.Wherein, MCE determines eNB according to area identification, is communicated between MCE and eNB by M2 interface, and eNB passes through M1 interface ip multicast bag from MBMS-GW, and when the traffic scheduling cycle arrives, by issuing service on the frame of specifying of eating dishes without rice or wine.The broadcast system specific implementation broadcast mode that the embodiment of the present invention provides as shown in Figure 8.Specific implementation process is as follows:

MCE receives the conversation message that MME sends, and carries area identification in conversation message.MCE determines whether corresponding AC or cell according to area identification.

Concrete, as shown in Fig. 8 801, MCE determines whether corresponding AC according to the area identification received, the mapping table of inquiry business region and AC can be passed through, as inquiry has having AC, then distribute conversation message to these AC determined, and then determining the AP that will receive conversation message, realize eMBMS business by WIFI, specific implementation process as in the foregoing embodiment, repeats no more herein.

MCE according to the eNB list of area identification inquiry correspondence, thus can also determine the eNB that will receive eMBMS session, if inquire service area according to the area identification received have corresponding cell, then distributes eMBMS session to the eNB belonging to cell.Concrete, the QoS of survice parameter that MCE is corresponding according to eMBMS session, judge that whether the resource in MBSFN sub-frame resource pool is enough, if enough, distribute Physical Multicast Channel (physicalmulticastchannel, PMCH) resource taken needed for, and LCID corresponding to session distribute.MCE mono-aspect is by SessionStart flow process, and notice eNB sets up corresponding M1 interface (eNB sends the Multicast Routing that MBMSGW to this eNB is set up in the application of IGMPreport message); On the other hand, by SchedulingInfo flow process, notice eNB reserves corresponding interface-free resources.ENB configures according to this interface-free resources, notifies UE by system message, and is untied by the ip multicast bag received from MBMSGW, and is cached; When the traffic scheduling cycle arrives, by issuing service on the frame of specifying of eating dishes without rice or wine, thus realize eMBMS broadcasting service by eNB.

Optionally, as shown in Figure 7, AC and AP can be integrated, realizes the function of AC and the function of AP by single AP, and specific implementation as shown in Figure 9, in the existing discussion in detail of previous embodiment, repeats no more herein.

When MCE is according to the service area mark received, inquire service area when having corresponding cell and AC respectively, then MCE can distribute session respectively to eNB and AC that service area is corresponding, and now different UE can realize eMBMS business respectively by WIFI and LTE as carrying.

Specifically illustrate for a UE, if this UE only enters the WIFI overlay area of broadcast system shown in this embodiment, so this UE can realize eMBMS business by WIFI as carrying, if this UE only enters the LTE overlay area of this broadcast system, so this UE can realize eMBMS business by LTE as carrying, if the region that this UE enters has WIFI to cover and LTE covers simultaneously, namely the cell that the AC that the service area carried in the message that MCE distributes is corresponding is corresponding with the service area carried has the overlay area of repetition, and this UE enters this repetition overlay area, so for the UE supporting WIFI business and LTE service concurrence, UE can receive eMBMS business by LTE network, also other eMBMS business tines more can be received by WIFI network, such as UE can receive CCTV1-CCTV5 five channels by LTE network, also other different channels such as CCTV11-CCTV14 can be received by WIFI network.

WIFI covers can as the alien frequencies overlay area of eMBMS, can the broadcasting service of flexible customization zonule based on WIFI coverage, and therefore, user can realize more compartmentalization programme content in the overlay area of WIFI by UE.

For the UE not supporting WIFI business and LTE service concurrence, eMBM broadcasting service can be received by WIFI when UE enters separately WIFI network; EMBM broadcasting service can be received by LTE network when UE enters separately LTE network; When UE enters WIFI network and the common overlay area of LTE network, UE can select priority access WIFI network, thus can by the network reception eMBMS business of WIFI.
