具体实施方式
下面结合附图及具体实施例对本申请作进一步详细的说明。
随着通信技术的不断发展,MAC控制元素(CE,Control elements)的种类出现了大幅度增长,MAC控制内容逐渐增多,例如对接入和回传一体化(IAB,Integrated Access and Backhaul)、侧行链路(Sidelink)和辅助上行链路(SUL)等各种场景下链路的控制,MAC已成为控制功能实体。
管控分离的MAC架构由无线管理(Radio Management)、用户管理(UE Management)、业务或者数据管理(Traffic Management)、链路控制(Link Control)四大类组成。其中,“管”面包括无线管理(Radio Management)、 用户管理(UE Management)、业务或者数据管理(Traffic Management);“控”面包括链路控制(Link Control)。
“管”面主要任务是实现对无线资源、计算资源、用户行为和业务特征进行管理,包括特征学习,特征归纳总结,特征预测等相对于空口调度传输时间间隔(TTI,Transmission Time Interval)而言相对慢速的管理功能,比如一次产生可以适用于时效性为N个TTI的管理命令,其中N大于1,一般N的取值不超过10个TTI。
其中,无线管理(Radio Management):用于完成空口无线资源和物理信道的在线仿真和编排,实现半动态和大时延尺度的管理。
用户管理(UE Management):用于监控、记录并计算每个用户收发的数据特征、空口信道质量、在空口交互时用户的状态、调度优先级等。信息的存储和处理以用户设备(UE,User Equipment)为单位。
业务管理(Traffic Management):用于监控MAC运行过程中处理的所有在空口传输的数据信息,包括上层发送的业务数据包,用户在空口发送的控制信息等;记录并计算每个用户收发的数据特征,得到每种业务的特征值;最终得到面向MAC调度的数据传输模型和空口数据传输的QoS特征值。
链路控制(Link Control):用于监控每个用户的每个空口链路(如PHY Link)的接收和发送的质量,实现针对用户接收或者发送的数据特征和空口链路质量的空口链路选择功能。当具有空口链路功能的设备与该设备连接时,完成对该新空口链路的连接管理。空口链路:指的是发送端的MAC到接收端的MAC之间的逻辑链路,包括MAC-PHY之间的链路、PHY物理链路、空口无线信号三部分组成,即发送端的MAC-PHY之间的链路、PHY物理链路、用于发送和接收的空口无线信号、接收端对等的MAC-PHY之间的链路、PHY物理链路。
“控”面主要是根据每个TTI的调度,产生TTI级别的空口链路控制,空口链路包括MAC层和物理层(PHY层)之间的连接,PHY层到空口无线信号的链路总成。包括对链路的选择、切换、链路间的配对、链路上功能的选择等。
以上MAC架构,再引入新功能(例如AI)基础上,各部分功能之间的关系需要定义,并且这种架构无法确保灵活性和可扩展性。而SBA架构在5G的核心网中得到应用,SBA的主要特点是各功能模块之间可以通过标准的服务模型实现灵活交互(服务),每个组件可以根据需要进行灵活加载。基于此,本申请实施例的主要目的在于提出一种SBA架构的MAC功能。
本申请实施例提供了一种MAC功能。图1为本申请实施例的MAC功能的一种可选组成结构示意图;如图1所示,所述MAC功能包括:第一MAC和第二MAC;其中,所述第一MAC和所述第二MAC连接;

本实施例中,所述第一MAC(例如云MAC或集中MAC)用于对第一时间周期内的功能(或功能组件、功能体、服务等)进行控制,如负责针对第二MAC服务的空口的快速控制,处理各种功能(或功能组件、功能体、服务等)的时间周期可以在第一时间周期之间或者产生的控制信息时域有 效性为第一时间周期;示例性的,所述第一时间周期例如为1毫秒(ms)~100ms。
在一些可选实施例中,所述第一MAC包括一个或多个功能组件(或功能、功能体、服务等)和总线控制器,两个功能组件(或功能、功能体、服务等)之间以及每个功能组件(或功能、功能体、服务等)与总线控制器之间通过总线连接。其中,所述总线控制器(Bus Controller)也可称为总线(bus)。

配置为数据塑形的功能组件(MAC-Data Shaping)。
本实施例中的所述数字孪生,也可称为数字镜像、数字化映射、数字双胞胎等等,表示针对目标功能或目标服务进行仿真和模拟,建立虚拟模型(或仿真模型),可以理解,数字孪生是充分利用物理模型、传感器以及运行参数等数据进行仿真过程,得到的数字孪生体也可称为虚拟空间中对实体产品的镜像,也即数字孪生是采用信息技术对物理实体的组成、特征、功能和性能进行数字化定义和建模的过程。
本实施例中,所述第二MAC(如边缘MAC),用于对第二时间周期内的功能(或功能组件、功能体、服务等)进行控制;所述第二时间周期小于或者等于所述第一时间周期,如负责空口实时的处理,处理各种功能(或功能组件、功能体、服务等)的时间周期可以在第二时间周期之内或者产生的控制信息时域有效性为第二时间周期之内,示例性的,所述第二时间周期例如为1ms之内,甚至为符号(Symbol)级别,即微秒(us)级别。
在一些可选实施例中,所述第二MAC包括多个功能组件(或功能、功能体、服务等),任意两个功能组件(或功能、功能体、服务等)之间通过总线(bus)连接。
在一些可选实施例中,所述第二MAC包括的功能组件包括以下至少之一:
配置为无线接入技术控制的功能组件(MAC-RAT Ctrl);其中,所述无线接入技术(RAT,Radio Access Technology)可根据服务的终端能力、空口信道的特征、业务特征中的至少一种信息进行选择;
配置为物理功能编排的功能组件(MAC-PHY Orch);其中,所述物理功能编排可基于服务于用户的信道使用的编码方式、编排方式、空口无线信号的发送方式等进行编排;

在一些可选实施例中,所述第一MAC中的各功能组件和所述第二MAC中的各功能组件均采用相同的总线接口进行扩展。
本实施例中,所述第一MAC和所述第二MAC之间通过总线(bus)进行连接。其中,总线(bus)具有以下特征:
1、为MAC各个功能的扩展提供统一接口;无论是第一MAC扩展其上的各种功能,还是第二MAC扩展其上的各种功能,使用相同的总线(Bus)接口进行扩展。第一MAC与第二MAC之间使用相与第一MAC/第二MAC内部使用相同的总线(Bus)接口,当一个第二MAC接入第一MAC时,通过总线(Bus)进行消息(如握手消息)的传递,并通过总线(Bus)进行数据信息交互;
2、总线(Bus)提供统一的消息传递方式,即所述第一MAC和所述第二MAC之间通过特定消息格式进行数据交互;所述特定消息格式中包括以下字段:表示源功能组件(或源功能体、源功能)的字段、表示目标功能组件(或目标功能体、目标功能)的字段、表示消息类型的字段和表示消息数据的字段。如表1所示,该特定消息格式可包括消息格式和快速路由方式源功能体标识(Src FID,Source Function Entity Identity)(源功能体标识用于表示源功能体或源功能组件),目的功能体标识(Target FID,Target Function Entity Identity)(目标功能体标识用于表示目标功能体或目标功能组件),消息类型(Msg Type),消息体(Msg Data)等等。
表1
源功能体(Src FID)
目标功能体(Target FID)
消息类型(Msg Type)
消息类型(Msg Type)
消息数据(Msg Data)
消息数据(Msg Data)
其中,Src FID(即表示源功能组件或源功能体的字段)和Target FID(即表示目标功能组件或源功能体的字段)可以是长度为1个字节的整数 倍,比如为1字节(byte),则说明第一MAC和第二MAC各自最多可以存在256个功能体(Function Entity)或功能组件;
Msg Type(即表示消息类型的字段)为长度为1个字节的整数倍,比如为2byte,用来标识可以传递的消息类型,例如包括两个功能体(或功能组件)之间交互的所有的消息类型;
Msg Data(即表示消息数据的字段)包括两个功能体(或功能组件)之间交互的所有信息内容,例如可以是直接按照交互的信息进行组建的字节块。
在一些可选实施例中,所述总线控制器,配置为在所述第二MAC首次接入所述第一MAC时,执行所述第二MAC的注册过程,建立所述第二MAC的数字孪生体;还配置为在所述第一MAC中的第一功能组件与所述第二MAC中的第二功能组件之间首次交互时,建立所述第一功能组件和所述第二功能组件之间的路由。
本实施例中,总线(bus)具有自主路由控制的功能,例如具有交换机(Switch)功能。根据第一MAC和第二MAC之间互联的物理链路的信息(该信息在第一MAC和第二MAC之间进行连接时,发送至总线控制器(Bus Controller),总线控制器具有自动连接建立的能力,当功能(Function)A与功能(Function)B第一次交互时,总线控制器根据源地址和目的地址判断两个功能体的路由,如果为第一次交互,则自动建立二者之间的路由;如果已经存在该路由,则直接把数据发送给目的功能体,并在后继的传输中不再进行控制,以实现两个功能体在逻辑上的点对点通信。
采用本申请实施例的技术方案,一方面实现了SBA下的分布式MAC,另一方面实现了MAC中的各功能组件通过服务模型灵活交互,各功能组件可通过实际需要进行灵活加载,提升了MAC功能的灵活性和可扩展性。
基于前述实施例,本申请实施例还提供了一种通信方法,所述通信方 法应用于MAC功能中的第一MAC中,所述MAC功能如前述实施例中所述的MAC功能。图2为本申请实施例中的通信方法的流程示意图;如图2所示,所述方法包括:

在步骤103中,所述第一MAC对所述第二MAC的总线进行注册,具体的,所述第一MAC的总线控制器(Bus Controller)对所述第二MAC的总线进行注册,包括基于该第二MAC的身份标识(若所述第一身份标识有效,则该身份标识为第一身份标识,若所述第一身份标识无效,则该身份标识为新分配的第二身份标识)和总线相关信息(包括总线能力信息,例如包括以下至少之一:总线能够承载的逻辑通道数、总线的最大带宽、总线的最大吞吐量等等)进行注册。
在步骤103中,第一MAC向第二MAC发送接入响应(Access Response)消息,所述接入响应消息中包括身份标识(若所述第一身份标识有效,则该身份标识为第一身份标识,若所述第一身份标识无效,则该身份标识为新分配的第二身份标识)和检测包。
在步骤104中,第二MAC向第一MAC发送检测响应包,该检测响应包也可称为心跳包、心跳检测包或总线响应包。所述检测响应包中包括所述第二MAC的相关信息。在一些可选实施例中,所述第二MAC的相关信 息包括以下至少之一:第二MAC中功能组件的数量、第二MAC中每个功能组件的类型、第二MAC能力和特征信息。
