It should be noted that TS 36.300 9 also allows MCE be deployed inside eNodeB. Interfaces related to E-UTRAN (i.e. M1, M2 and M3) ar

36、e introduced in this document. For MBMS, control signaling and user plane data packet are distributed from the EPC to E-UTRAN through different interfaces. square4 Control plane interfaces M3, M2 interface are pure control plane interfaces. M3 between MME and MCE mainly carries MBMS session manageme

37、nt signaling. A MCE is connected to one or more than one eNBs within the same MBSFN through M2 interface mainly for MBMS session management signaling and radio configuration signaling. square4 User plane interface M1 interface is a pure user plane interface.

38、PP TS 36.440 version 13.0.0 Release 13A MBMS GW is connected to multiple eNBs through M1 interface for data distribution. Reference points within EPC are not in the scope of this document. Please refer to TS 23.246 8 for details. 5 Functions of M1 interface for MBMS 5.1 General M1 Interface: MBMS GW

39、 eNB The M1 interface is the user plane interface of MBMS between MBMS GW and eNB. IP multicast is used to deliver the downlink packets over the M1 interface and there is no uplink data over M1 radio network layer. SYNC protocol (TS 25.446 7) is used over the M1 interface to keep the content synchro

40、nization for MBMS service data transmission. 5.2 Multicast group management function IP multicast is used to deliver the packets over the M1 interface. The M1 interface has the function to manage the IP multicast groups. The MBMS GW maintains the IP multicast groups. The MBMS GW allocates the IP mul

41、ticast group address when the session arrives, and may release it at session stop. At the eNB side, the eNB joins the IP multicast group to receive the MBMS User Plane data at session start, leaves the IP multicast group when the session stops, may leave the IP multicast group when the session suspe

42、nds and may rejoin the IP multicast group when the session resumes. 5.3 Content synchronization function The packets delivered over M1 interface will be synchronously transmitted by eNBs. To support the inter-eNB content synchronization, SYNC protocol layer is defined between BM-SC to eNB, which is

43、used to carry additional information that enable eNBs to identify the timing for radio frame transmission and detect packet loss. Every packet in M1 contains the SYNC protocol information which is encapsulated at BM-SC. 6 Functions of M2 interface for MBMS 6.1 General M2 Interface: MCE eNB An Applic

44、ation Part (M2AP) is defined in TS 36.443 4 for this interface, which conveys at least radio configuration data for the multi-cell transmission mode eNBs and Session Control Signaling. SCTP (IETF RFC 4960 10) is used as signaling transport i.e. Point-to-Point signaling is applied. 6.2 M2 interface s

45、etup and configuration update functions The M2 Setup (respectively the eNB and MCE configuration update) function allows to exchange (respectively update) application level data needed for the eNB and MCE to interoperate correctly on the M2 interface after the TNL association has become operational.

46、 6.3 MBMS Session management function MBMS session management function is responsible for starting, updating, and stopping MBMS sessions. ETSI ETSI TS 136 440 V13.0.0 (2016-01)93GPP TS 36.440 version 13.0.0 Release 136.3.1 M2 service context management function The M2 service context management func

47、tion supports the establishment of the necessary overall initial service context including MBMS E-RAB context, M2 signalling connection ID(s), etc. The establishment of the overall initial M2 service context is initiated by the MCE. The M2 service context management function also supports the releas

48、e of the context previously established in the eNB due to service termination. The release of the context is triggered by the MCE. 6.3.2 MBMS E-RAB management functions The MBMS E-RAB service management function is responsible for establishing and releasing E-UTRAN resources for service data transpo

49、rt. The establishment of E-UTRAN resources is triggered by the MCE. The release of E-UTRAN resources is triggered by the MCE. 6.3.3 M2 link management function The M2 signalling link management function provides a reliable transfer of the radio network signalling between eNBs and MCE. The SCTP is used to support the exchange of M2 Application Protocol (M2AP) signalling messages between eNBs and MCE. 6.3.4 MBMS Service Suspension and Resumption function The MBMS Service Suspension function allows the MC
