Description

一种数据发送方法、装置及系统 技术领域
本申请涉及通信领域,尤其涉及一种数据发送方法、装置及系统。
背景技术
目前,无线通信中提出了终端设备同时使用第四代移动通信技术(the 4th Generation mobile communication technology,4G)、第五代移动通信技术(the 5th-Generation mobile communication technology,5G)的双连接技术,即演进的陆地无线接入网(Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network,E-UTRAN)及新无线电(New Radio,NR)双链接(E-UTRAN-NR Dual Connectivity,EN-DC)技术。在EN-DC技术中,终端设备从长期演进(Long Term Evolution,LTE)网络和5G NR网络同时获取数据,也就是同时使用多个基站的无线资源,多个基站分为主站和从站,一般也称之为主节点(Master Node,MN)和辅节点(Secondary Node,SN)。
双连接引入了“分流承载”的概念,数据的分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)终结在NR侧,即在NR的PDCP层将数据分流到多个基站。当NR侧的设备发生变更但是LTE侧没有变更的时候进行NR侧的SN变更(change)流程,在该流程中NR侧变更的源5G基站(Source gNB)的残余数据需要转移至NR侧变更的目的5G基站(Target gNB)。
第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)37.340的协议中定义了NR change的协议流程,该协议流程中定义了源gNB向目的gNB转发数据流的流向是通过4G网络中的演进型基站(Evolved Node,eNB)中转。
由于NR的覆盖低于LTE,NR侧的SN change流程频频发生,频繁的SN Change产生的大量残留数据的转发,会降低LTE网络自身的性能。

具体实施方式
3GPP 37.340的协议中定义了NR change的协议流程如图1a和图1b所示。其中,图1a示意了MN主动发起NR change的协议流程,图1b定义了SN主动发起NR change的协议流程。下面简单描述3GPP 37.340的协议中定义的NR change的协议流程,对 其具体实现不进行赘述。
如图1a所示,MN主动发起NR change的协议流程可以包括:
S101、MN向T-SN发送节点增加请求消息。
S102、T-SN向MN发送节点增加请求消息的响应消息。
S103、MN向S-SN发送节点释放请求消息。
S104、S-SN向MN发送节点释放请求消息的响应消息。
S105、MN与UE进行RRC连接重配置。
S106、SN节点从S-SN转移到T-SN。
S107、S-SN向MN发送残余数据。
S108、MN向T-SN转发残余数据。
如图1b所示,SN主动发起NR change的协议流程可以包括:
S201、SN向MN发送节点变更请求消息。
S202、MN向T-SN发送节点增加请求消息。
S203、T-SN向MN发送节点增加请求消息的响应消息。
S204、MN与UE进行RRC连接重配置。
S205、MN与S-SN进行节点变更确认。
S206、SN节点从S-SN转移到T-SN。
S207、S-SN向MN发送残余数据。
S208、MN向T-SN转发残余数据。
从图1a和图1b示意的3GPP 37.340的协议中定义的NR change的协议流程的S107和S108、S207和S208,残余数据通过MN转发至T-SN。由于NR的覆盖低于LTE,NR侧的SN change流程频频发生,频繁的SN Change产生的大量残留数据的转发,会降低LTE网络自身的性能。
基于此,本申请提出一种数据发送方法,用于在双连接的节点变更流程中,源节点设备向目的节点设备发送数据,其基本原理是:双连接的节点变更流程中,源节点设备向目的节点设备直接传输数据,避免其他节点设备转发,以提高双连接的节点变更流程的数据转发效率。
本申请中描述的节点设备,可以为双连接技术中终端设备接入的两个网络中的基站的部分或全部;当节点设备为基站的部分时,节点设备可以为基站中的功能单元或者至少一个芯片。基站,即无线通信系统中为终端设备提供通信服务的网络侧设备。在不同制式的无线通信系统中,基站可以有不同的称呼,但均可以理解为本申请中描述的基站。本申请实施例对于基站的类型也不进行具体限定。例如,通用移动通信系统(Universal Mobile Telecommunications System,UMTS)中的基站称之为基站(Base Station,BS);LTE系统中的基站称之为演进型基站(evolved Node B,eNB);5G系统中的基站称之为下一代基站(generation nodeB,gNB)等等,此处不再一一列举。凡是无线通信系统中为终端设备提供通信服务的网络侧设备,均可以理解为本申请描述的基站。
本申请中描述的终端设备,是指用户使用的移动通信设备的部分或全部。例如终端设备可以为用户设备(User Equipment,UE)或者其他。其中,UE可以为手机、平 板电脑、笔记本电脑、超级移动个人计算机(Ultra-mobile Personal Computer,UMPC)、上网本、个人数字助理(Personal Digital Assistant,PDA)、电子书、移动电视、穿戴设备、个人电脑(Personal Computer,PC)等等。在不同制式的通信系统中,终端设备可以有不同的称呼。本申请实施例对于终端设备的类型也不进行具体限定。
本申请提供的数据发送方法,应用于如图1所示的双连接无线通信系统架构中。如图1所示,该双连接无线通信系统架构中包括终端设备101、第一网络的基站102、及第二网络的基站103。终端设备101使用基站102及103的无线资源,从第一网络和第二网络同时获取数据。
需要说明的是,图1仅仅是通过举例对双连接无线通信系统架构的示意。对于双连接无线通信系统架构中包括的终端设备101、基站102及基站103的数量、类型,均可以根据实际需求配置,图1并不是对此内容的具体限定。
还需要说明的是,本申请中描述的节点设备,可以为图1中示意的基站102或者基站103的部分或全部,因此,图1中示意的基站102或者基站103代表了本申请描述的节点设备,可以直接替换应用,此处不再进行赘述。
示例性的,图1示出的双连接无线通信系统架构中的第一网络可以为LTE网络、第二网络可以为5G网络,或者其他网络。对于本申请的方案所应用的网络的类型,本申请实施例对此并不进行具体限定。
在描述本申请实施例之前,此处对本申请实施例中涉及的名词进行解释。
源节点设备,是指双连接架构中进行节点变更时,从网络中释放的节点设备。
目的节点设备,是指双连接架构中进行节点变更时,在网络中增加的用于替代源节点设备的节点设备。
第一节点设备,是指双连接架构中源节点设备所在的网络之外的另一个网络中的基站设备。
节点变更流程,是指双连接架构中使用目的节点设备替换源节点设备的过程。
直接数据前传,是指节点间直接发送数据的方式。
本申请实施例的说明书和权利要求书中的术语“第一”和“第二”等是用于区别不同的对象,而不是用于描述对象的特定顺序。例如,第一网络设备和第二网络设备等是用于区别不同的网络设备,而不是用于描述设备的特定顺序。
在本申请实施例中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念,便于理解。
