具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容,下面结合附图对本发明实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本发明实施例。
需要说明的是,本发明实施例的技术方案可以应用于各种通信系统,例如:长期演进(Long Term Evolution,简称“LTE”)系统及LTE系统的演进系统,例如先进的长期演进(Advanced long term evolution,简称“LTE-A”)系统、新无线(New Radio,简称“NR”)系统及NR系统的演进系统,例如免授权频谱上的NR(NR-based access to unlicensed spectrum,简称“NR-U”)系统、或下一代通信系统等。
不失一般性地,参见图1,其示出了非典型示例的通信系统1的结构示意,该通信系统可以由UE、接入点#1以及接入点#2组成,接入点可以是用于与UE通过无线通信链路进行通信的固定站,可以是LTE中的演进型基站(Evolutional Node B,简称“eNB”或“eNodeB”),或者中继站,或者车载设备、可穿戴设备以及NR网络中的网络设备,例如5G基站(gNB),或者未来演进的PLMN网络中的网络设备等。每个接入点都可以为特定的地理区域提供通信覆盖,如图1所示为例,接入点#1能够为实线圈所示的地理区域提供覆盖,接入点#2能够为虚线圈所示的地理区域提供覆盖。可以理解地,接入点提供通信覆盖的物理区域可以称之为“小区”,而且每个接入点可以在不同频率上为不同的特定地理区域提供覆盖,因此,每个接入点可以为多个小区提供通信覆盖。而在本发明实施例中,为了对技术方案进行清楚地阐述,仅以每个接入点仅提供一个小区覆盖为例进行说明。所以在本发明实施例中,术语“小区”与“接入点”可以认为是等同的。
在图1中,UE可以是固定的或移动的,并且也可以被称为接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备可以是无线局域网(Wireless Local Area Networks,简称“WLAN”)中的站点(STAION,简称“ST”),可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,简称“SIP”)电话、无线本地环路(Wireless Local Loop,简称“WLL”)站、个人数字处理(Personal Digital Assistant,简称“PDA”)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及下一代通信系统,例如,第五代通信(fifth-generation,简称“5G”)网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,简称“PLMN”)网络中的终端设备等。
UE可以经由下行链路和上行链路上的传输来与一个或多个接入点进行通信。下行链路(或者说是前向链路)是指从接入点到UE的通信链路,而上行链路(或者说是反向链路)是指从UE到接入点的通信链路。在图1中,具有双箭头的实线表示UE和接入点之间的通信。具有单个箭头的虚线表示UE试图由接入点#1所覆盖的小区(称之为源小区)切换到接入点#2所覆盖的小区(称之为目标小区)。
在图1所示的通信系统中,可以支持网络发起的和/或UE发起的切换,对于网络发起的切换,UE可以在系统指示时执行切换,并且系统可以例如 基于由UE进行的并发送到源小区的测量结果来为UE选择试图切换到的目标小区。
参见图2,其示出了UE从源接入点(如图1中的接入点#1)的源小区切换到目标接入点(如图1中的接入点#2)的目标小区的消息流程示意,为清楚起见,下面仅描述与UE切换相关的信令和功能。
UE可以最初与源接入点的源小区进行通信。源接入点可以为UE配置测量过程(步骤1),并且UE可以向源接入点发送测量报告(步骤2)。源接入点可以做出要切换(HO,HandOver)该UE的决策(步骤3),并且可以向目标接入点发布切换请求消息(步骤4)。源接入点可以向目标接入点发送UE的上下文信息。上下文信息可以包括RRC上下文、SAE承载上下文、和/或用于支持UE进行通信的其它信息。目标接入点可以执行准许控制并且可以接受UE的切换(步骤5)。然后,目标接入点可以向源接入点返回切换请求确认(Ack)(步骤6)。
然后,源接入点可以向UE发送切换命令(步骤7)。切换命令可以包括UE可以试图切换到的目标接入点的目标小区。该切换命令也可以包括其它信息,比如目标接入点的配置信息(例如,无线链路配置)。UE可以使用该配置信息来向目标接入点发送信令。
然后,UE可以与源接入点断开,选择目标接入点的目标小区以试图切换,并与所选小区执行随机接入。对于随机接入,UE可以在随机接入信道(RACH)上向所选小区发送随机接入前导码,以同步到该小区(步骤8)。并且UE可以从目标接入点的目标小区接收随机接入响应(步骤9)。随机接入响应可以包括诸如上行链路(UL)资源分配和UE的时间提前量之类的信息以及可能的其它信息。
当成功接入目标接入点的目标小区时,UE可以向该小区发送切换确认消息以指示针对UE的切换过程完成(步骤10)。目标接入点可以发送切换完成消息以向核心网设备通知UE已经改变了接入点(步骤11)。然后,核心网设备可以将UE的数据路径从源接入点切换到目标接入点。核心网设备也可以向目标接入点返回切换完成Ack消息(步骤12)。目标接入点可以向源接入点发送释放资源消息以指示UE的成功切换(步骤13)。当接收到释放资源消息时,源接入点可以释放UE的资源(步骤14)。
对于图2所示的流程,需要说明的是,在切换过程中,目标接入点通常会将目标小区的系统信息SI传递至源节点,随后源接入点将目标小区的SI传递至UE。从而使得UE在获得目标小区的SI之后,能够快速地接入 到目标接入点的目标小区并完成切换。
但需要指出的是,在目前的5G NR系统中,SI可以包括最小系统信息Minimum SI以及其他系统信息Other SI;其中,Minimum SI是采用默认广播方式的方式,包含在同步信号传输块(SS block,Synchronization Signal block)中,每个波束beam中都会包含一个Minimum SI;而Other SI则采用按需广播或者单播的方式。Other SI可能包括多个独立的系统信息块(SIB,SI Block),每个独立的SIB可能会广播,也可能不会,并且每个SIB的值也可以独立地改变。与此同时,SIB与系统信息区域(SIA,System Information Area)相关联,也就是说,在同一SIA中,不同小区但相同类型的SIB相同。基于此,在上述目标接入点将目标小区的系统信息SI通过源节点传递至UE的过程之中,如果目标小区与源小区处于相同的SIA,那么目标小区的部分或全部SI会与源小区的部分或全部SI相同,所以目标小区的SI通过源节点传递至UE的过程中,被传递的目标小区的部分或全部SI可以认为是冗余信息,从而增大了传递过程中目标小区与源小区之间的信息交互资源消耗,降低了切换过程中信息交互的效率。
为了避免上述情况发生,本发明实施例基于图1所示的通信系统架构以及图2所示的切换流程,提出了一种信息传输的方法,参见图3,该方法可以包括:
S301:目标小区获知与源小区的系统信息属于相同SIA的第一系统信息;
S302:目标小区将自身的系统信息中除所述第一系统信息以外的第二系统信息发送至源小区。
通过图3所示的技术方案,目标小区将除与源小区系统信息属于相同SIA的系统信息以外的其他系统信息发送至源小区。避免了相同系统信息的重复发送,也避免了冗余信息的传输,从而降低了目标小区与源小区之间的信息交互资源消耗,提高了切换过程中信息交互的效率。
对于图3所示的技术方案,在具体实施过程中,若目标小区自身所有的系统信息均与源小区的系统信息属于相同的SIA,那么第一系统信息为目标小区所有的系统信息;若目标小区的部分系统信息与源小区的系统信息属于相同的SIA,那么第一系统信息为目标小区中部分的系统信息。
基于此,就需要对目标小区所有的系统信息与源小区的系统信息是否属于相同的SIA进行判断,从而使得目标小区获知所述第一系统信息。在本发明实施例中,可以在目标接入点或终端侧进行上述判断过程,参见以 下任一优选示例。
优选示例一
目标小区从自身的系统信息中获知与源小区的系统信息属于相同SIA的第一系统信息,可以包括:
目标小区接收由源小区发送的所述源小区的系统信息;
目标小区将自身的每个系统信息的SIA信息与所述源小区的每个系统信息的SIA信息进行比对,根据比对结果获知与源小区的系统信息属于相同SIA的第一系统信息。
结合图2所示的切换流程,在一种可能的实现示例中,源小区可以在执行步骤4时,将源小区的系统信息封装在切换请求中发送至目标小区,目标小区通过解析切换请求以获得源小区的系统信息;随后,目标小区可以将自身的每个系统信息的SIA信息与源小区的每个系统信息的SIA信息进行比对,于是目标小区就能够从自身的系统信息中获得与源小区的系统信息属于相同SIA的第一系统信息。可以理解地,基于上述比对结果,第一系统信息可以为目标小区所有的系统信息;也可以为目标小区中部分的系统信息。
优选示例二
目标小区从自身的系统信息中获知与源小区的系统信息属于相同SIA的第一系统信息,可以包括:
目标小区接收源小区发送的第一指示信息;其中,所述第一指示信息由UE发送至源小区,且所述第一指示信息用于指示所述目标小区的系统信息中与源小区的系统信息属于相同SIA的第一系统信息标识;
目标小区基于所述第一指示信息中的第一系统信息标识获知所述第一系统信息。
结合图2所示的切换流程,在一种可能的实现示例中,UE在执行步骤2的过程中,可以将源小区的邻小区进行测量,并在测量过程中获知所述源小区的每个邻小区的系统信息所属的SIA;随后,UE将所述源小区的每个系统信息的SIA信息分别与每个邻小区的系统信息的SIA信息进行比对,从而获知每个邻小区的系统信息与源小区的系统信息属于同一SIA的系统信息;接着,UE可以将每个邻小区的系统信息与源小区的系统信息属于同一SIA的系统信息标识封装于测量报告中发送至源小区;最后,源小区在获得测量报告并进行切换决策之后,根据切换的目标小区从每个邻小区的系统信息与源小区的系统信息属于同一SIA的系统信息标识中获取目标小 区的系统信息中与源小区的系统信息属于相同SIA的第一系统信息标识,并将目标小区的第一系统信息标识封装于切换请求中发送至该目标小区。所以,目标小区可以基于切换请求中所封装的第一系统信息标识从自身的系统信息中获知与源小区的系统信息属于相同SIA的第一系统信息。
举例来说,设定源小区Cell0的邻小区可以包括Cell1、Cell2和Cell3,UE在针对Cell1、Cell2和Cell3进行测量的过程中,通过测量Cell1、Cell2和Cell3的广播信号获知Cell1、Cell2和Cell3各自的系统信息,并获取Cell1、Cell2和Cell3各自的系统信息的SIA信息;而且由于UE处于Cell0的覆盖范围,所以UE也能够通过接收Cell0的广播或单播获知Cell0的系统信息,并获取Cell0的系统信息的SIA信息。因此,UE将Cell1、Cell2和Cell3各自的系统信息的SIA信息分别与Cell0的系统信息的SIA信息进行比对,从而基于比对结果就能够得到Cell1、Cell2和Cell3各自的系统信息中与Cell0的系统信息属于同一SIA的系统信息标识;接着,UE可以将上述系统信息标识封装在RRC信令中,优选可以是测量报告中发送至Cell0。Cell0在接收到测量报告后决策切换至Cell2,于是,Cell0就可以将测量报告中Cell2的系统信息标识作为第一系统信息标识封装在切换请求中发送至Cell2;随后,Cell2根据切换请求中的第一系统信息标识从自身的系统信息中获知与cell0的系统信息属于相同SIA的第一系统信息。仍然可以理解地,第一系统信息可以为目标小区所有的系统信息;也可以为目标小区中部分的系统信息。
基于上述第一系统信息可能出现的两种情况,对于步骤S302来说,目标小区将自身的系统信息中除所述第一系统信息以外的第二系统信息发送至源小区,也可以参照以下任一优选方案进行实现:
优选方案一
针对第一系统信息为目标小区所有的系统信息,则第二系统信息为空,目标小区可以向源小区发送第二指示信息;所述第二指示信息用于指示源小区通知UE在切换完成后继续使用源小区的系统信息。
具体来说,当第一系统信息为目标小区的所有系统信息时,那就说明源小区和目标小区的系统信息都属于同样的系统信息区域,那么为了避免相同系统信息的重复发送,以及避免冗余信息的传输,目标小区的所有系统信息均不需要向源小区发送,基于此,目标小区可以向源小区发送明确的第二指示信息来指示源小区通知UE将源小区的系统信息作为切换完成后继续使用的系统信息。结合图2所示的切换流程,目标小区可以在执行 步骤6的时候,在切换请求Ack中增加用于承载第二指示信息的字段;源小区在接收到承载有第二指示信息字段的切换请求Ack之后,通过步骤7的切换命令通知UE将源小区的系统信息作为切换完成后继续使用的系统信息。
优选方案二
针对第一系统信息为目标小区中部分的系统信息,则第二系统信息为目标小区中除第一系统信息以外的其他部分的系统信息,目标小区可以向源小区发送第三指示信息;所述第三指示信息用于指示源小区通知UE在切换完成后针对第一系统信息继续使用源小区的系统信息并且将第一系统信息以外的其他系统信息使用第二系统信息。
具体来说,当第一系统信息为目标小区中部分的系统信息,那么第二系统信息为目标小区中除第一系统信息以外的其他部分的系统信息,为了避免相同系统信息的重复发送,以及避免冗余信息的传输,目标小区中的第一系统信息不需要向源小区发送而第二系统信息需要先源小区发送,基于此,目标小区可以向源小区发送第三指示信息来指示源小区通知UE在切换完成后针对第一系统信息继续使用源小区的系统信息并且针对第一系统信息以外的其他系统信息使用第二系统信息。同样结合图2所示的切换流程,目标小区可以在执行步骤6的时候,在切换请求Ack中增加用于承载第三指示信息的字段;源小区在接收到承载有第三指示信息字段的切换请求Ack之后,通过步骤7的切换命令通知UE在切换完成后针对第一系统信息继续使用源小区的系统信息并且针对第一系统信息以外的其他系统信息使用第二系统信息。
基于图3所示的技术方案,对于用户设备来说,本发明实施例提出了一种信息传输的方法,如图4所述,可以包括:
S401:UE在测量源小区的邻小区的过程中,获取每个邻小区的系统信息所属的SIA;
S402:UE将所述源小区的每个系统信息的SIA信息分别与每个邻小区的系统信息的SIA信息进行比对,获得每个邻小区的系统信息与源小区的系统信息属于同一SIA的系统信息;
S403:UE将每个邻小区的系统信息与源小区的系统信息属于同一SIA的系统信息标识通过RRC信令发送至源小区;所述RRC信令用于所述源小区在完成决策目标小区后,将所述目标小区的系统信息中与所述源小区的系统信息属于相同SIA的第一系统信息标识发送至所述目标小区。
需要说明的是,图4所示的技术方案,在可能的实现过程中,RRC信令可以优选为UE在测量过程中生成的测量报告,具体过程如图3中优选示例二所述,在此不再赘述。
基于图3所示的技术方案,对于源小区来说,本发明实施例提出了一种信息传输的方法,如图5所述,可以包括:
S501:源小区将所述源小区的系统信息发送至目标小区;
S502:源小区接收所述目标小区发送的在所述目标小区的系统信息中除第一系统信息以外的第二系统信息;其中,所述第一系统信息包括:在所述目标小区的系统信息中,与源小区的系统信息属于相同系统信息区域SIA的系统信息。
需要说明的是,图5所示的技术方案,其具体实现过程如图3中优选示例一所述,在此不再赘述。
此外,参见图6,对于源小区,本发明实施例还提出了一种信息传输的方法,所述方法包括:
S601:源小区接收用户设备UE发送的RRC信令;其中,所述RRC信令承载有每个邻小区的系统信息与所述源小区的系统信息属于同一SIA的系统信息标识;
S602:源小区在完成决策目标小区后,将所述目标小区的系统信息中与所述源小区的系统信息属于相同SIA的第一系统信息标识发送至所述目标小区;
S603:源小区接收所述目标小区发送的在所述目标小区的系统信息中除第一系统信息以外的第二系统信息。
可以理解地,图6所示的技术方案,其具体实现过程如图3中优选示例二所述,在此不再赘述。
