具体实施方式
发明人在发明过程中注意到：
由于相关技术中的4G MBMS技术，不允许处于idle或in-active态的UE主动发起MBS传输模式的转换请求，导致这些处于idle或in-active态的UE接收质量得不到满足，同时也无法使得MBS业务适用于更高性能要求的业务传输特性。
而5G NR(5G新空口，5G New Radio)作为新一代无线接入技术网络，应该能满足更高性能需求的业务传输特性，例如：高可靠，存在大量连接用户的业务需求。在本公开实施例提供的技术方案中，允许处于idle或in-active态的UE在接收5G MBS业务时，能根据MRB的接收质量，自主是否发起传输模式转换请求，从而满足5G MBS网络兼顾资源效率和UE下行接收质量的双重考虑。
下面结合附图对本公开的具体实施方式进行说明。
在说明过程中，将分别从UE与NG-RAN侧的实施进行说明，然后还将给出二者配合实施的实例以更好地理解本公开实施例中给出的方案的实施。这样的说明方式并不意味着二者必须配合实施、或者必须单独实施，实际上，当UE与NG-RAN(下一代无线接入网；NG：下一代，Next Generation；RAN：无线接入网，Radio Access Network)分开实施时，其也各自解决UE侧、NG-RAN侧的问题，而二者结合使用时，会获得更好的技术效果。
图3为UE侧的MBS模式处理方法实施流程示意图，如图所示，包括：
步骤301、处于idle或in-active态的UE，通过多播信道接收某MBS业务；
步骤302、当所述UE判断所述多播信道接收质量无法满足要求时，向NG-RAN发起MBS模式转变请求。
图4为NG-RAN侧的MBS模式处理方法实施流程示意图，如图所示，包括：
步骤401、NG-RAN接收处于idle或in-active态的UE发送的MBS模式转变请求；
步骤402、NG-RAN根据MBS模式转变请求，针对所述UE发起相应的PTM到PTP配置转变过程。
具体的，一个处于idle或in-active态的UE，正在通过多播信道(如：MRB)接收某MBS业务情况下，当其判断其多播信道接收质量无法满足要求情况下，允许其向网络侧发起MBS模式转变请求。
而NG-RAN根据此信息，针对该UE发起相应的PTM到PTP配置转变过程。
实施中，UE可以根据以下方式之一或者其组合判断所述多播信道接收质量：
判断RSRP或RSRQ，或SINR是否超过网络预配置的阈值；
根据MRB PDCP PDU的按序接收结果，以及网络预配置的定时器进行判断；
根据物理层HARQ重传的次数进行判断。
相应的，进一步包括：NG-RAN向UE发送判断所述多播信道接收质量的以下参数之一或者其组合：
RSRP或RSRQ，或SINR是否超过网络预配置的判断阈值；
网络预配置的定时器；
物理层HARQ重传的次数。
具体地，UE根据下述可能的条件评估MRB的接收质量：
判断其RSRP(Reference Signal Received Power，参考信号接收功率)和RSRQ(Reference Signal Received Quality，参考信号接收质量)，或SINR(信号与干扰和噪声比，Signal to Interference plus Noise Ratio)是否超过网络预配置的阈值；具体实施中，测量得到的RSRP或RSRQ，或SINR通常情况可以进行一定的平滑处理；
根据MRB PDCP(分组数据聚合协议，Packet Data Convergence Protocol)PDU(协议数据单元，Protocol Data Unit)的按序接收结果，以及网络预配置的定时器，例如：若乱序定时器超时，标明数据传输发生丢包；
根据物理层HARQ(混合自动重传请求，Hybrid automatic repeat request)重传的次数等信息，具体实施中，物理层HARQ重传次数可以是单位时间内所统计得到的。
实施中，UE采用RRC消息向NG-RAN发起MBS模式转变请求。
相应的，NG-RAN接收所述UE采用RRC消息发起的MBS模式转变请求。
具体的，UE采用RRC(无线资源控制，Radio Resource Control)消息通知网络期望进行MBS模式转变；
实施中，向NG-RAN发起MBS模式转变请求，包括：
UE通过NAS信令携带期望转变的MBS业务列表信息，所述MBS业务列表信息将由AMF将此期望转变的MBS业务列表信息通知给NR-RAN。
相应的，NG-RAN接收所述UE发起的MBS模式转变请求，包括：
接收AMF通知的MBS业务列表信息，所述MBS业务列表信息是AMF根据所述UE通过NAS信令携带的期望转变的MBS业务列表信息转变的。
可选地，UE通过NAS(非接入层，Non Access Stratum)信令携带期望转变的MBS业务列表信息，随后AMF(接入和移动管理功能，Access and Mobility Management Function)将此期望转变的MBS业务列表信息通知给NR-RAN。
下面用实例进行说明。
实施例1：
本例中UE发起MBS接收模式转变请求。
1：一个处于idle或in-active态UE，正在通过多播信道(如：MRB(MBMS Radio Bearer，MBMS无线承载；MBMS：Multimedia Broadcast/Multicast Service，多媒体广播\组播服务)在某个小区里接收某MBS业务。
2：UE根据预先保存的该MBS业务的RSRP或RSRQ，或SINR判断阀值，或者，是预配置的乱序定时器，评估其MRB的接收质量。
如果发生下述条件，UE将认为MRB接收质量无法满足需求：
判断其MRB的RSRP或RSRQ，或SINR超过网络预配置的阈值；
一旦接收到乱序的MRB PDCP PDU，将开启相应的乱序定时器，若乱序 定时器超时，标明数据传输发生丢包；
如果物理层HARQ重传的次数超过预配置的次数限制。
3：当MRB的接收质量无法满足要求时，该UE将发起MBS接收模式转变请求流程。
4：UE首先触发RRC连接建立过程，随后通过特定RRC消息，将期望进行MBS模式转变的MBS业务列表发送给网络；
具体地，在新定义的RRC消息中，如：MBS mode request(MBS模式请求)，或是重用相关技术中的RRC消息中，如：UE assistance information(UE辅助信息)消息，包含期望转变的MBS业务列表信息。
可选地，UE通过NAS信令携带期望转变的MBS业务列表信息，随后AMF针对该UE期望转变的MBS业务发起PDU session setup(PDU会话建立)或modification(修改)等过程；并将此期望转变的MBS业务列表信息通知给NR-RAN。
具体地，此消息可能是重用NG接口的UE associated(UE相关)消息，如上述消息，或是定义新的MBS相关消息，如：MBS会话更新或MBS信息通知等。
5：NG-RAN根据此信息，针对该UE发起相应的PTM到PTP配置转变过程。
具体地，包括但不限于下述步骤：
网络侧发起RRC重配置消息，消息中携带针对相应MBS会话的DRB(数据无线承载，Data Radio Bearer)配置信息。
接收到此重配置消息后，UE将执行DRB配置过程，即完成MRB到DRB的转变。
配置成功后，UE将返回RRC重配置完成消息。
6：UE开始采用单播方式接收相应的MBS业务。
实施例2：
本例中网络配置MBS相应的参数。
1：针对特定的MBS会话，网络侧决定将其与UE接收质量判断相关的参数发送给UE，参数中包括但不限于：
该MBS业务的RSRP或RSRQ，或SINR判断阀值，或者，
预配置的乱序定时器，或是；
物理层HARQ重传的次数等。
2：网络侧采用系统消息传输的方式，例如：采用与MBS相关的SIB(系统信息块，System Information Block)消息，或是与MBS相关的MCCH配置消息，将上述参数发送给UE。
3：如果与UE接收质量判断相关的参数发生了变更，网络侧也通过系统消息的变更，或是MCCH的修改等机制，触发信息的变更。
4：感兴趣该MBS业务接收的UE，接收到此信息后，将按照上述实例1的说明进行操作。
