5G网络中存在非独立工作的小区(non standalone cell,NSA cell),该类小区不广播SIB1系统消息,因而UE不能直接通过该类小区获取其他SIB(如SIB2/3/4等)的调度信息。该类小区可以作为辅服务小区(Secondary Cell,SCell)配置给UE。对于连接态UE来说,该类小区的其他SIB的调度信息是通过主控小区(如UE的主服务小区(Primary Cell,Pcell))的无线资源控制(Radio Resource Control,RRC)信令告知给UE的。而对于非连接态UE来说,由于其不处于RRC连接态,因而其并没有所属的主控小区,进而是无法获取NSA cell的其他SIB的调度信息以及其他SIB所承载的信息的。
当NSA cell提供MBMS时,根据目前的协议,非连接态UE是无法获取该类小区上关于MBMS的配置信息,进而不能通过该类小区接收其可能感兴趣的MBMS。
为了解决上述问题,本公开实施例提供了一种MBMS配置信息的获取方法、装置及通信设备,使得非连接态UE可以从NSA cell上正确接收MBMS。此外,通过本公开提供的MBMS配置信息的获取方法,连接态UE也可以直接获取NSA cell上的MBMS配置信息,而不需要网络侧通过专用信息告知UE,可降低信令开销。

下面以第一消息为主信息块(Master Information Block,MIB),第二消息为SIB为例,结合具体的实施例对本公开的MBMS配置信息的获取方法进行进一步介绍。
实施例一
本实施例中,通过MIB指示非独立工作小区是否提供MBMS配置信息。
新空口(New Radio,NR)中传统(legacy)MIB存在预留比特位,为了使NSA cell能够提供MBMS配置信息,可将预定义的接收图样与该预留比特进行关联,通过预定义的接收图样可以获取MBMS配置相关的信息。
一具体示例中,当该预留比特位取值为“0”时,表示提供当前UE接收到的MIB的小区不提供MBMS配置信息,即不提供MBMS;当该预留比特位取值为“1”时,表示接收当前MIB的小区提供MBMS配置信息,即提供MBMS。
对于legacy UE,当接收到NSA Cell提供的MIB时,不读取上述预留比特位,该类UE认为这个比特位是一个预留比特位;
对于MBMS capable UE,即具有MBMS能力的UE,UE会读取上述比特位。当UE读取到该比特位取值为“0”时,可以获知该NSA cell是不提供MBMS的,当UE读取到该比特位取值为“1”时,可以获知该NSA cell是提供MBMS的。
对于NSA MBMS cell(即提供MBMS的NSA cell),MBMS capable UE根据预留比特的取值确定是否需要通过与其关联的预定义的接收图样获取MBMS的配置信息。预定义的接收图样可是一个或多个,当预定义了一个接收图样时,UE确定通过该接收图样获取MBMS的配置信息;当预定义了多个接收图样时,UE可以根据自身特性选定接收图样,MBMS capable UE确定接收图样后,通过该接收图样获取MBMS的配置信息,获取方法可以是以下任意一种:
通过所述接收图样获取MBMS专用SIB1信息,如SIBbis_MBMS,该系统消息可以只携带承载MBMS配置信息的系统消息(如新引入的SIB10)的调度信息,通过读取SIBbis_MBMS中的调度信息,可以知道获取承载MBMS配置信息的系统消息(如SIB10)的接收方式;
通过所述接收图样获取承载MBMS配置的系统消息,如SIB 13,通过接收该系统消息获取MBMS的配置信息。
实施例二
本实施例中,通过专用系统消息提供MBMS配置信息。
legacy MIB只剩下一个预留比特位,为便于后续扩展,NSA Cell可以不使用该预留比特以用于MBMS。为了使NSA Cell能够提供MBMS相关配置,需要使用专用的MIB和SIB1用于MBMS调度。
具体地,UE基于接收到的指示信息确定该小区提供了一个MBMS专用的主系统信息,如MIBbis_MBMS。其中,所述指示信息可以是物理层提供的,可以基于以下一项或多项信息的组合确定:
在一个MBMS专用时间同步块上接收到主系统消息,确定该小区提供了一个MBMS专用的主系统消息;
在一个MBMS专用PBCH信道上接收到主系统消息,确定该消息提供了一个MBMS专用的主系统消息。
当接收到该指示信息时,MBMS capable UE的行为如下:
在预定义的资源位置上接收该MBMS专用MIB;
读取该MBMS专用MIB中获取该小区上关于MBMS的配置信息。
其中,获取该小区上关于MBMS的配置信息的方式包括以下任意一种:
MBMS的配置信息通过SIB承载,如新引入的SIB10,所述的SIB的调度信息由MBMS专用SIB1承载,而所述的MBMS专用MIB携带了所述的MBMS专用SIB1的资源位置信息;
MBMS的配置信息通过SIB承载,如新引入的SIB10,而所述的MBMS专用MIB携带了所述的SIB的调度信息;
实施例三
本实施例中,通过SA cell(独立工作的小区)提供NSA MBMS cell的信息。
一具体示例中,SA cell提供邻小区关于MBMS的信息,其中,所述MBMS信息包括以下一项或多项组合:
指示某邻小区是否是NSA MBMS cell的指示信息;
某邻小区MBMS cell提供的MBMS列表。
当MBMS capable UE获知某邻小区是NSA MBMS cell时,通过预定义的接收图样获取NSA MBMS cell上关于MBMS的配置信息。其中,获取方法可以是以下任意一种:
通过所述接收图样获取MBMS专用SIB1信息,如SIBbis_MBMS,该系统消息可以只携带承载MBMS配置信息的系统消息(如新引入的SIB10)的调度信息,通过读取SIBbis_MBMS中的调度信息,可以知道获取承载MBMS配置信息的系统消息(如SIB10)的接收方式;
通过所述接收图样获取承载MBMS配置的系统消息,如SIB 13,通过接收该系统消息获取MBMS的配置信息。
另一具体示例中,SA cell提供邻小区关于MBMS的信息,其中,所述MBMS信息包括以下一项或多项组合:
指示某邻小区是否是NSA MBMS cell的指示信息;
某邻小区MBMS cell提供的MBMS列表;
某NSA cell的MBMS专用SIB1的资源位置信息;
所述SA cell与某NAS MBMS cell的系统帧和/或子帧和/或时隙的偏差值。
其中,当SA cell和NSA MBMS cell的系统帧是完全对齐时,所述的偏差值可以不携带在MBMS信息中。
其中,NSA cell的MBMS专用SIB1的资源位置信息可以是以SA cell的无线系统帧为基础提供的资源位置,此时如果SA cell和MBMS cell的无线系统帧没有对齐,需要提供所述的偏差值;也可以是以MBMS cell的无线系统帧为基础提供的资源位置信息,此时不需要提供所述的偏差值。
当MBMS capable UE获知某邻小区是NSA MBMS cell时,通过SA cell提供的MBMS专用SIB1的资源位置信息获取MBMS专用SIB1。其中,所述MBMS专用SIB1可只携带承载MBMS配置的系统消息的调度信息,MBMS capable UE通过MBMS专用SIB1中的调度信息去接收承载MBMS配置的系统消息,进而获取对应NSA cell上的MBMS配置信息。
另一具体示例中,SA cell提供邻小区关于MBMS的信息,其中,所述MBMS信息包括以下一项或多项组合:
指示某邻小区是否是NSA MBMS cell的指示信息;
某邻小区MBMS cell提供的MBMS列表;
某邻小区上关于MBMS控制信息的配置信息;所述配置信息可以是NSA MBMS cell发送MBMS控制信息的资源位置;
某邻小区上关于MBMS控制信息变更的配置信息;
所述SA cell与某NAS MBMS cell的系统帧和/或子帧和/或时隙的偏差。
其中,当SA cell和NSA MBMS cell的系统帧是完全对齐时,所述的偏差值可以不携带。
其中,所述MBMS控制信息的配置信息和MBMS控制信息变更的配置信息可以是以SA cell的无线系统帧为基础提供的资源位置,此时如果SA cell和MBMS cell的无线系统帧没有对齐,需要提供所述的偏差值;也可以是以MBMS cell的无线系统帧为基础提供的资源位置信息,此时不需要提供所述 的偏差值。
其中,MBMS控制信息变更的配置信息可以是一比特的指示信息,比如,取值为“0”时,表示未发生变更,取值为“1”时,表示发生变更,此时MBMS capable UE在MBMS控制信息的发送位置接收变更后的MBMS控制信息;所述的MBMS控制信息变更的配置信息可以是NSA MBMS cell下发MBMS控制信息变更的资源位置,UE可在对应的资源位置检测是否发生MBMS控制信息变更,当发生MBMS控制信息变更时,UE在MBMS控制信息的发送位置接收变更后的MBMS控制信息。
当MBMS capable UE获取某邻小区是NSA MBMS cell时,基于从SA cell获取到的NSA MBMS cell上的MBMS控制信息的配置信息,去特定的资源位置接收MBMS配置信息。
实施例四
本实施例中,NSA MBMS cell提供legacy MIB和SIB1,通过禁止驻留指示区分legacy UE和知道该小区是NSA MBMS cell的MBMS capable UE。
一具体示例中,NSA MBMS cell提供legacy MIB和legacy SIB1。其中,legacy MIB中携带禁止驻留的指示信息(如cellbar=“true”)。所述legacy SIB1可只携带与MBMS相关的系统消息的调度信息。
当UE从所述NSA MBMS cell上接收到MIB消息时,UE的行为如下:
Legacy UE读取到所述MIB中携带的禁止驻留的指示信息,则认为该小区是被禁用的,UE将不再试图通过该MIB中携带的legacy SIB1的资源位置信息去接收legacy SIB1;
若MBMS capable UE知道该小区是一个NSA MBMS cell,则当其读取到MIB中携带的禁止驻留的指示信息,认为该小区是被禁用的,但UE将试图通过MIB中携带的legacy SIB1的资源位置信息去接收legacy SIB1;
若MBMS capable UE不知道该小区是一个NSA MBMS cell,则当其读取到所述MIB中携带的禁止驻留的指示信息,认为该小区是被禁用的,UE将不再试图通过MIB中携带的legacy SIB1的资源位置信息去接收legacy SIB1。
其中,MBMS capable UE获知某个小区是否是NSA MBMS cell可以通过以下途径:
通过邻小区指示信息获知某小区是否是NSA MBMS cell,如SA cell指示;
通过NSA MBMS中MIB携带的指示信息获知某小区是否是NSA cell,如使用legacy MIB中的预留比特位指示某小区是否是NSA cell。
另一具体示例中,NSA MBMS cell提供legacy MIB和legacy SIB1。其中,legacy SIB1携带禁止驻留的指示信息(如cellReservedForOtherUse=“true”),并且可只携带与MBMS相关的系统消息的调度信息。
当UE从NSA MBMS cell上接收到MIB消息时,根据MIB中携带的legacy SIB1的资源位置信息去接收legacy SIB1。当接收到SIB1时,UE的行为如下:
Legacy UE读取到所述SIB1中携带的禁止驻留的指示信息,则认为该小区是被禁用的,UE将不试图通过legacy SIB1中携带的其他SIB(如新引入的MBMS相关的SIB10)的调度信息获取其他SIB;
若MBMS capable UE知道该小区是一个NSA MBMS cell,则当其读取到所述SIB1中携带的禁止驻留的指示信息,认为该小区是被禁用的,UE将试图通过legacy SIB1中携带的其他SIB(如新引入的MBMS相关的SIB10)的调度信息获取其他SIB;
若MBMS capable UE不知道该小区是一个NSA MBMS cell,则当其读取到所述SIB1中携带的禁止驻留的指示信息,认为该小区是被禁用的,UE将不再试图通过MIB中携带的legacy SIB1的资源位置信息去接收legacy SIB1。
其中,MBMS capable UE获取某个小区是否是NSA MBMS cell可以通过以下途径:
通过邻小区指示信息获取某小区是否是NSA MBMS cell,如SA cell指示;
通过NSA MBMS中MIB携带的指示信息获取,如使用legacy MIB中的预留比特位指示是否是NSA cell;
通过NSA MBMS cell上的SIB携带指示信息获取,如在SIB中增加是否是NSA Cell的指示信息。
