实施例一
本发明实施例一公开一种数据中转传输方法,应用于第一用户设备,参考
图1,所述方法可以包括以下步骤:
S101:接收来自用户设备UE的UE信令包。
所述UE信令包的来源UE,可以是承载本发明方法的第一用户设备之外的其他UE,即接入中继UE的接入UE。在本发明其他实施例中,所述UE信令包的来源UE,还可以是承载本发明方法的第一用户设备,即中继UE。
本申请仅对信令数据的中继进行描述。
现有普通UE的原有协议栈,即实现其拨打电话、发送短信息等终端功能所需的协议栈包括:用于对收、发用户数据提供技术支持的数据面协议栈,以及用于对收、发信令数据提供技术支持的控制面协议栈。
其中,控制面协议栈由底层至上层依次包括PHY(Physical Layer、物理层)协议、MAC(Media Access Control,媒体介入控制层)协议、RLC(Radio LinkControl,无线链路控制层)协议、PDCP(Packet Data Convergence Protocol、分组数据汇聚协议)、RRC(Radio Resource Control,无线资源控制)协议和NAS(Non-access stratum、非接入层)协议,UE依据上述协议栈中的各种协议实现其相应层所需的功能。
为了实现中继方案,使UE在具备拨打电话、发送短信息等终端功能的基础上,同时具有能够为无线资源控制提供技术支持的数据中继功能,参考图2示出的中继UE协议栈结构,本实施例在UE原有控制面协议栈的RRC层之上或RRC层中增加了一个虚拟的中继功能子层,即中继功能子层可以为RRC层之上的一个独立协议层,也可以是对原有RRC层的功能增加。
在此基础上,如图2所示,将PHY、MAC、RLC、PDCP、RRC、中继功能子层、NAS层协议作为UE的UE功能侧协议,实现为UE以UE角色收、发基站数据提供技术支持;将PHY、MAC、RLC、PDCP、RRC、中继功能子层协议作为UE的中继功能侧协议,实现为UE以中继角色收、发接入UE的数据及对接入UE进行无线资源控制提供技术支持;其中,本实施例中,中继功能侧和UE功能侧独立具备各自的RLC、MAC、PHY、PDCP及RRC层,在本发明其他实施例中,中继功能侧和UE功能侧还可以通过共用一个或多个上述层实现将UE功能侧和中继功能侧的共有协议进行合并,以减少冗余。
中继功能侧和UE功能侧可通过其共有的中继功能子层实现两功能侧的逻辑衔接,基于此,UE在中继数据的过程中,可实现其在UE角色与中继角色间
的角色转换。例如,UE在UE功能侧以UE角色接收来自于基站的待中转信令数据,并将其在中继功能子层进行相应处理,之后处理后的信令数据进入另一功能侧——中继功能侧,同时UE由UE角色转换为中继角色,最终,待转发的信令数据被UE的中继功能侧以中继角色转发出去。
在UE原有协议栈的RRC层之上或RRC层中增加中继功能子层后,UE同时具备终端功能及中继功能,成为中继UE,且由于所添加的中继功能子层在RRC层之上或RRC层中,实现了将RRC层协议纳入了中继UE的中继功能侧协议体系,从而可为中继UE对接入UE进行无线资源控制提供技术支持,提升了中继UE对QoS的支持能力。
技术人员可依据中继UE协议栈中涵盖的RRC协议,在中继UE中配置所需的RRC功能,例如建立和维护UE-to-relay(中继)链路、并对UE-to-relay链路进行管理等,实现为基站分担部分RRC功能,即一部分RRC功能由基站承载,而另一部分RRC功能则由中继UE承载,相比于现有技术中全部RRC功能均需由基站承载的特点,应用本发明时,可通过使中继UE为基站承担部分RRC功能,来适当降低对接入UE的RRC控制时延。
以下对中继功能子层的功能进行定义。参考图4,以对UE上行数据(UE需向基站发送信令)进行中继为例,A1/A2/A3是来自UE功能侧的无线信令,即中继UE自身的信令,如中继UE高层NAS信令或RRC信令;B1/B2/B3是来自中继功能侧的无线信令,即接入UE的信令。
为了实现中继形态数据(来自接入UE的待中转信令)与UE形态数据(中继UE的RRC/NAS层产生的常规用户信令)的区分,本实施例的中继功能子层具备如下功能:基于聚合原理的不同,可将来自UE功能侧及中继功能侧的无线信令按如下各方式中的相应方式进行映射:
一、基于信令来源
创建新的RRC/NAS信令,或借用原有RRC/NAS信令并对该原有信令进行扩展,以承载中继的所有RRC/NAS信令;
将所有来源于同一功能侧的RRC/NAS信令聚合并打包放在新建或扩展的RRC/NAS信令中统一传输。
其中,对同一功能侧的RRC/NAS信令进行聚合、打包后形成的信令包中,包含各信令的来源(如UE标识符)、各信令的信令类型(如RRC连接请求、RRC
连接重配置请求)等不限于上述特征的信息。
二、基于信令类型
将来源于UE功能侧和中继功能侧的同种类型的RRC/NAS信令合并并打包传输。譬如,将UE功能侧和中继功能侧的RRC Connection Reconfiguration(RRC连接重配置请求)信令合并并打包一起传输。
其中,打包所得的信令包中需给出各信令的来源(如UE标识符)以供基站eNB加以区分。
三、基于逻辑信道/信道组
将来源于相同逻辑信道/信道组的信令一并打包传输。如将来源于UE功能侧和中继功能侧的同一逻辑信道或信道组的信令打包成一个信令包进行传输。最终打包所得的信令包中同样给出了各信令的来源UE标识。
四、独立传输
不对来源于UE功能侧和中继功能侧的RRC/NAS信令进行合并,即每个RRC/NAS信令均按照常规的RRC处理,由UE功能侧对其进行独立传输。
中继功能子层在对RRC/NAS信令进行映射所得的信令包中,包括一个中继协议头,为区分各信令是来源于中继UE的UE功能侧还是中继功能侧,可在中继协议头中设置一标识位;进一步地,为区分来源于中继功能侧但属于不同接入UE的RRC/NAS信令,还可以在中继协议头中增加一标识位,用以区分不同的UE来源。
以上对中继功能子层的设置及功能定义可作为本发明方法的预处理部分。
在此基础上,若接入UE需通过中继UE向基站eNB传输信令,有信令中转需求,参考图5,则接入UE在RRC层或NAS层发出RRC信令或NAS信令,所发出的RRC信令或NAS信令依次经过该接入UE的常规协议栈(RRC、PDCP、RLC、MAC、PHY)进行相应的格式封装,最终由该UE的射频将封装为相应格式的信令包发射出去。
S102:在所述UE为所述第一用户设备之外的其他UE时,基于第一预设协议组对所述UE信令包进行解封装处理,得到第一目的信令。
以中继功能子层为RRC层之上的一个独立协议层为例,当中继UE的中继侧物理层接收到接入UE发射的信令包后,向上递交信令包,使其依次经过中继侧协议栈的PHY、MAC、RLC、PDCP、RRC协议层,各协议层对其进行解
封装处理后得到第一目的信令,并将第一目的信令递交至中继功能子层处理。
需要说明的是,实际应用本申请时,当将中继功能子层设计为RRC层的功能添加时,中继UE的物理层接收到接入UE的UE数据包后,向上传递数据包,使其依次经过中继侧协议栈的PHY、MAC、RLC、PDCP协议层、进行解封装处理,并将其递交至RRC层,在RRC层执行所需的中继格式封装。
在本发明其他实施例中,当中继UE需向基站eNB传输信令时,中继UE的RRC层或NAS层发出RRC信令或NAS信令,并将其递交至中继功能子层进行处理。
S103:基于第二预设协议组对所述第一目的信令进行格式封装处理,得到第一目的信令包;所述第一预设协议组或所述第二预设协议组包括无线资源控制RRC协议。
仍以中继功能子层为一独立协议层为例,若中继UE的中继功能子层接收到来源于多个或一个UE的M个第一目的信令,则中继功能子层依据预设的聚合规则,将所述M个第一目的信令聚合为P个第一中间信令包;M为大于1的自然数,P为不小于1的自然数,且P≤M;
并对每个所述第一中间信令包进行中继格式封装,得到P个第二中间信令包;所述第二中间信令包包括中继协议头,所述中继协议头包括S个UE标识,所述S个UE标识分别为构成所述第一中间信令包的S个第一目的信令的来源UE标识,S为不小于1的自然数,且S≤M;
之后,UE功能侧的RRC层、PDCP层、RLC层、MAC层、PHY层分别依据其对应的协议对所述第二中间数据包进行格式封装,得到P个第一目的信令包。
若中继UE的中继功能子层接收到的第一目的信令的个数为1个,则中继功能子层直接对所述第一目的信令进行中继格式封装,得到第三中间信令包;所述第三中间信令包包括中继协议头,所述中继协议头包括UE标识,该UE标识为所述第一目的信令的来源UE标识;之后,UE功能侧的RRC层、PDCP层、RLC层、MAC层、PHY层分别依据其对应的协议对所述第三中间信令包进行格式封装,得到第一目的信令包。
在本发明其他实施例中,若中继功能子层为RRC协议层的功能添加,则在RRC协议层中执行上述聚合处理及中继格式封装处理即可,并在执行中继格式封装后,将封装结果递交至UE功能侧的PDCP层,之后,依次由UE功能侧的
PDCP层、RLC层、MAC层、PHY层继续对其执行格式封装。
S104:将所述第一目的信令包发送至移动通信网络节点。
最终,中继UE的UE侧物理层可将所述第一目的信令包直接发送至基站eNB,或通过多跳中继将所述第一目的数据包传输至基站。即,所述移动通信网络节点可能为基站,也可能为基于本申请方法的下一跳中继。
本申请的中继方案适用于TSC(Terminal Small Cell,终端微基站)通信场景及D2D(Device-to-Device,终端对终端)直连通信场景,基于本申请的方案,UE可在提供终端功能的同时,作为上述两种通信场景中的一中继节点提供数据中继功能。
由以上方案可知,本发明接收来自UE的UE信令包;在所述UE不是承载本发明方法的第一用户设备时,基于第一预设协议组对UE信令包进行解封装处理,并基于第二预设协议组对解封装结果进行格式封装,最后,将格式封装的结果发送至移动通信网络节点。其中,所述第一预设协议组或所述第二预设协议组包括RRC协议。可见本发明将RRC协议纳入了实现中继功能所依托的协议体系,即将RRC协议纳入了中继UE的中继侧协议体系,为无线资源控制提供了技术支持,提升了中继UE对QoS的支持能力,在应用本发明时,技术人员可基于中继UE涵盖的RRC协议在中继UE配置所需的RRC功能,以适当降低无线资源控制过程中的时延。
实施例二
本实施例二公开一种数据中转传输方法,应用于第一用户设备,区别于实施例一中数据中转传输方法的上行信令(即UE向基站传输信令)中继功能,本实施例二的方法实现了下行信令(基站向UE传输信令)中继功能,参考图6,所述方法可以包括以下步骤:
S601:接收来自移动通信网络节点的节点信令包。
本实施例中,所述移动通信网络节点为基站eNB,或基于本申请方法的下一跳中继。
S602:基于第三预设协议组对所述节点信令包进行解封装处理,得到第二目的信令及所述第二目的信令对应的目的UE标识,所述第三预设协议组包括RRC协议。
S603:在所述目的UE标识对应的UE为所述第一电子设备之外的其他UE时,基于第四预设协议组对所述第二目的信令、目的UE标识进行格式封装,得到第二目的信令包。
S604:将所述第二目的信令包发送至所述目的UE标识对应的目的UE。
中继UE对下行信令的中继为对上行信令中继的逆过程,若所述节点信令包包括K个信令及与所述K个信令一一对应的K个目的UE标识,K为大于1的自然数,则:
中继UE的UE功能侧物理层接收到基站的节点信令包后,依次经由UE功能侧的PHY、MAC、RLC、PDCP、RRC层对节点信令包进行解封装,并在中继功能子层中将解封装后的节点信令包拆分为K个信令及与所述K个信令一一对应的K个目的UE标识。
若拆分所得的信令的目的UE标识对应中继UE,则中继功能子层可直接将该信令传输至中继UE的高层即RRC层或NAS层;若所述信令的目的UE标识对应接入UE,则中继功能子层将该信令向下传递至中继功能侧协议栈的RRC、PDCP、RLC、MAC、PHY协议层进行格式封装,之后将其发送至目的UE标识对应的接入UE,实现了下行信令的中继。
在本发明其他实施例中,若节点信令包中仅包括一个信令及一个目的UE标识,则中继UE的中继功能子层无需对UE功能侧的RRC层递交的节点信令包(解封装后的)执行信令包拆分。
