Problems solved by technology

[0004] In the eMBMS service, according to the 3GPP TS36300 protocol specification, the multipoint control channel (Multicast Control Channel, MCCH) and the multicast transmission channel (MulticastTransmission Channel, MTCH) on the evolved base station (evolved NodeB, eNB) side are multiplexed on the multipoint channel (Multicast Channel, MCH), and the MCH is mapped on the physical multipoint channel (Physical Multicast Channel, PMCH), so the MCCH and MTCH are multiplexed on the PMCH; when the PMCH carrying the MCCH on the eNB side does not exist, it will cause The eNB side stops the data transmission of the PMCH, which leads to the inability to send the data of the MCCH

Embodiment 1

[0084] Embodiment of the present invention - a schematic diagram of a detailed processing flow of a data sending method, as shown in Figure 7 shown, including the following steps:

[0085] In step 401, the eNB sends an M2 SET UP REQUEST message to the MCE.

[0086] Step 402, MCE replies M2 SET UP RESPONSE message to eNB;

[0087] Here, if the eNB does not receive the MBMS scheduling information indication message, it confirms that the PMCH carrying the MCCH does not exist;

[0088] The absence of PMCHs carrying MCCHs means that the number of PMCHs is N, but none of the N PMCHs carries MCCHs, and N is an integer greater than or equal to zero.

[0089] Step 403, the eNB sends a System Information Block Type13 message to the UE;

[0090] Specifically, the eNB sends a System Information Block Type13 message to the UE through the air interface;

[0091] Wherein, the content of the System Information Block Type13 message is configured according to the M2 SET UPRESPONSE message;...

Embodiment 2

[0099] A schematic diagram of a detailed processing flow of a data sending method in Embodiment 2 of the present invention, as shown in Figure 8 shown, including the following steps:

[0100] Step 501, eNB sends M2 SET UP REQUEST message to MCE.

[0101]In step 502, the MCE sends an M2 SET UP RESPONSE message to the eNB.

[0102] Step 503, MCE sends MBMS SCHEDULING INFORMATION message to eNB;

[0103] Here, the MBMS SCHEDULING INFORMATION message indicates that the PMCH carrying the MCCH does not exist;

[0104] Here, the absence of a PMCH carrying an MCCH means that the number of PMCHs is 0.

[0105] Step 504, eNB sends MBMS SCHEDULING INFORMATION RESPONSE message to MCE;

[0106] Here, the eNB confirms that the PMCH carrying the MCCH does not exist.

[0107] Step 505, the eNB sends a System Information Block Type13 message to the UE;

[0108] Specifically, the eNB sends a System Information Block Type13 message to the UE through the air interface;

[0109] Wherein, t...

Embodiment 3

[0117] A schematic diagram of a detailed processing flow of a data sending method in Embodiment 3 of the present invention, as shown in Figure 9 shown, including the following steps:

[0118] In step 601, the MCE sends an MCE CONFIGURATION UPDATE message to the eNB.

[0119] In step 602, the eNB sends an MCE CONFIGURATION UPDATE ACKNOLNOWLEDGE message to the MCE.

[0120] Step 603, MCE sends MBMS SCHEDULING INFORMATION message to eNB;

[0121] Here, the MBMS SCHEDULING INFORMATION message indicates that the number of PMCHs is N, and N is a positive integer, but none of the N PMCHs bears the MCCH.

[0122] Step 604, eNB sends MBMS SCHEDULING INFORMATION RESPONSE message to MCE;

[0123] Here, the eNB confirms that the PMCH carrying the MCCH does not exist.

[0124] Step 605, the eNB sends a System Information Block Type13 message to the UE;

[0125] Specifically, the eNB sends a System Information Block Type13 message to the UE through the air interface;

[0126] Wherein...

Abstract

The invention discloses a method for sending data. The method includes: when the base station confirms that the physical multicast channel carrying the multipoint control channel does not exist, sending a system information broadcast message; configuring a multicast / group broadcast message according to the system information broadcast message Broadcasting a single frequency network (MBSFN) area configuration message; performing data scheduling according to the configuration of the system information broadcast message or the MBSFN area configuration message; sending the MBSFN area configuration message. The invention also discloses two other data sending methods, base station, user equipment and multi-cell / multicast coordination entity.

Description

technical field [0001] The invention relates to signal processing technology in mobile communication, in particular to a data sending method and equipment. Background technique [0002] With the development of mobile Internet and large-screen mobile terminals, more and more mobile terminal users choose to process multimedia information services on the mobile terminal side, such as: video conferencing, live broadcast of events, online education, etc. Compared with ordinary data services, multimedia information services have the characteristics of high bandwidth occupation, long duration, sensitive delay requirements, and relatively fixed transmission content. In order to effectively utilize spectrum resources, the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) organization proposed Multimedia Broadcast and Multicast Service (MBMS). The MBMS service is a point-to-multiple service, namely: There is one data source and multiple data receiving targ...
