技术领域
本公开涉及通信技术领域,尤其涉及一种信息发送方法、接收方法及设备。
背景技术
如图1所示,为传统的无线通信采用蜂窝网络通信方式,即终端和网络侧设备通过通用用户网络(User to Network interface universal,Uu)接口进行上下行数据/控制信息的传输。Uu接口也被称作无线接口或空中接口。本文中,所述网络侧设备具体可以是基站。所述基站可以是5G及以后版本的基站,例如gNB、5G NR NB等,或者所述基站还可以其他通信系统中的基站,例如:eNB、无线局域网(Wireless Local Area Network,WLAN)接入点、或其他接入点等)。另外,基站也可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇。另外,在后文中基站也用于指代网络侧设备。
如图2所示,直接通信是指邻近的终端可以在近距离范围内通过直接通信链路(也称为Sidelink或者PC5)进行数据传输的方式。Sidelink链路对应的无线接口称为直接通信接口(也称为Sidelink接口或者PC5接口)。
为了扩展网络覆盖,相关技术引入了中继的解决方案。该中继可以是一个具有中继功能的终端。
如图3所示,为终端到网络的中继方式(UE-to-Network Relay)的示意图。对于UE-to-Network Relay,中继和网络之间的接口使用Uu接口,和被中继终端之间的接口使用PC5接口(也称之为直接通信接口,协议上描述为Sidelink)。中继和网络之间的链路对被中继终端而言可以称为回程链路(Backhaul link)。
如图4所示,相关技术的一种接入网通信系统架构,其中,接入网与核心网之间的接口定义为NG接口。接入网包括一组基站(gNB),这些gNB通过NG接口连接到5G核心网(5G Core,5GC)。基站可能有几个NG接入点朝向5GC。至少每个NG接入点(在基站或5GC中)应独立满足相关NG规范的要求。NG是一个逻辑接口。
从任何一个基站节点向5GC可能存在多个接入网与核心网之间的控制面(NG Interface Control Plane,NG-C)逻辑接口。然后,通过非接入层(NAS)节点选择功能,确定NG-C接口的选择。从任何一个基站节点向5GC可能存在多个接入网与核心网之间的用户面(NG Interface User Plane,NG-U)逻辑接口。NG-U接口的选择在5GC内完成,并由接入和移动管理功能(Access and Mobility Management Function,AMF)通知基站。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例,然而应当理解,可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反,提供这些实施例是为了能够更透彻地理解本公开,并且能够将本公开的范围完整的传达给本领域的技术人员。
本公开的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的本公开的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。说明书以及权利要求中“和/或”表示所连接对象的至少其中之一。
以下描述提供示例而并非限定权利要求中阐述的范围、适用性或者配置。可以对所讨论的要素的功能和布置作出改变而不会脱离本公开的精神和范围。各种示例可恰适地省略、替代、或添加各种规程或组件。例如,可以按不同于所描述的次序来执行所描述的方法,并且可以添加、省去、或组合各种步骤。另外,参照某些示例所描述的特征可在其他示例中被组合。
如背景技术所述的,为了扩展网络覆盖,相关技术引入了如图3所示的终端到网络(UE-to-Network Relay)的中继方案。在终端作为中继的场景下,中继终端和远端终端的AMF可以相同也可以不同。中继UE本身可以有业务传输,也可以没有业务传输。当中继终端没有自己的业务传输,而只是在为远端终端提供中继服务的时候,中继终端的AMF可能不知道中继终端的工作情况。此时,按照现有机制,AMF可能认为中继终端没有业务传输,从而发起中继终端的连接释放流程,导致中继业务的传输发生中断,影响了中继传输的可靠性。
为了解决以上问题中的至少一种,本公开实施例提供了一种信息发送方法、接收方法,应用于通过远端终端通过中继终端进行通信的场景中,能够避免或减少在上述情况下网络释放中继终端的网络连接的问题,从而提高中继业务传输的可靠性。
如图5所示,该方法在应用于基站时,包括:
步骤51,基站向核心网发送第一指示信息,所述第一指示信息用于指示第一中继终端的中继状态和/或指示是否释放第一中继终端的网络连接。
这里,第一中继终端是接入所述基站的某个中继终端,例如,所述第一中继终端是处于连接态的状态。所述第一指示信息可以包括用于指示第一中继终端的中继状态的第一信息,和/或,用于指示是否释放第一中继终端的网络连接的第二信息。所述第一信息用于指示第一中继终端的中继状态,本公开实施例中,所述中继状态具体可以包括以下任意一种:
状态a:中继功能未激活。
该状态a下,中继功能未激活是指,终端虽具备中继功能,但未开启该功能。
状态b:中继功能已激活,但未建立与远端终端的连接。
该状态b下,中继功能已激活,但中继终端尚未建立与任何远端终端之间的连接,也就是说,此时中继终端开启了中继功能,但还没有远端终端接入。
状态c:已建立与远端终端之间的连接,但未进行中继业务传输。
该状态c下,中继功能已激活,且已有远端终端接入该中继终端,但中继终端当前未进行中继业务的转发。
状态d:正在进行中继业务传输。
该状态d下,中继功能已激活,且已有远端终端接入该中继终端,并且中继终端当前正在进行中继业务的转发。
所述第二信息用于指示是否请求释放第一中继终端的网络连接,即指示请求释放第一中继终端的网络连接,或者,指示请求保持第一中继终端的网络连接。
本公开实施例中,指示请求释放第一中继终端的网络连接,具体可以包 括:指示请求释放为所述第一中继终端建立的基站与核心网的连接、所述第一中继终端与基站的连接、以及所述第一中继终端与核心网的连接中的至少一者。指示请求保持第一中继终端的网络连接,具体可以包括:指示请求保持为所述第一中继终端建立的基站与核心网的连接、所述第一中继终端与基站的连接、以及所述第一中继终端与核心网的连接中的至少一者。
通过基站向核心网发送上述第一信息和/或第二信息,使得核心网可以获取到第一中继终端的中继状态或者基站是否请求是否第一中继终端的网络连接的请求信息,这样核心网可以依据第一中继终端的中继状态或基站的请求信息,在第一中继终端未进行自身业务传输但进行中继业务传输的情况下,保持所述第一中继终端的网络连接,从而为核心网做出恰当的决策提供了信息支撑,进而可以减少或避免中继业务中断的发生,提高了中继业务传输的可靠性。
本公开实施例中,基站可以根据预设事件的触发,执行上述步骤51,具体的,所述基站在检测到预设事件时,向核心网发送所述第一信息和/或第二信息。具体的,所述预设事件可以包括以下至少一种:
1)所述基站接收到核心网发送的用于指示上报所述第一中继终端的中继状态或中继状态变化的第一消息。
这里,核心网可以主动的指示基站发送第一中继终端的中继状态或中继状态变化。例如,核心网在第一中继终端的连接定时器超时或接近超时的情况下,发送上述第一消息,以获取第一中继终端的中继状态。在第一消息指示上报中继状态时,基站在接收到所述第一消息,发送所述第一信息和/或第二信息。在第一消息指示上报中继状态改变时,基站在接收到所述第一消息后,若检测到第一中继终端的中继状态发生改变,则发送所述第一信息和/或第二信息。
2)所述基站确定出所述第一中继终端的中继状态发生改变。
这里,当基站检测到第一中继终端的中继状态发生变化,例如,从前文中的状态a变成状态b,此时将触发执行上述步骤51。
3)所述基站接收到核心网发送的用于释放所述第一中继终端的网络连接的释放消息,且所述第一中继终端处于第一中继状态,所述第一中继状态为 第一状态集合中的一种状态,所述第一状态集合包括以下状态中的至少一种:中继功能已激活,但未建立与远端终端的连接;已建立与远端终端之间的连接,但未进行中继业务传输;正在进行中继业务传输。
基站在接收到上述释放消息时,如果第一中继终端处于上述第一中继状态,此时基站可以挂起所述释放消息,并执行上述步骤51,将第一中继终端的中继状态等信息发送给核心网,以使向核心网可以基于上述信息,确认是否需要释放第一中继终端的网络连接。在上述步骤51之后,若所述基站再次上述释放消息,则将释放第一中继终端的网络连接。例如,在执行上述步骤51后,基站启动一定时器,在定时器超时前再次收到上述释放消息,则释放第一中继终端的网络连接;若所述定时器超时时,基站未再次收到上述释放消息,则可以丢弃所述释放消息。
基站可以基于上述预设事件的触发,执行上述步骤51,具体的,在上述步骤51中,所述基站可以仅向核心网发送一次所述第一信息和/或第二信息。或者,在上述步骤51中,所述基站周期性的向核心网发送所述第一信息和/或第二信息。例如,所述基站在接收到核心网发送的用于指示上报所述第一中继终端的中继状态或中继状态变化的第一消息后,可以周期性的发送所述第一信息和/或第二信息。进一步的,基站若接收核心网发送的用于指示取消上报所述第一中继终端的中继状态或中继状态变化的第二消息,则可以根据所述第二消息,停止发送所述第一指示信息。
另外,需要说明的是,在上述步骤51中,基站可以仅发送所述第一信息,或者,仅发送所述第二信息,或者,同时发送所述第一信息和第二信息。具体的,基站可以通过以下方式中的至少一种,获取所述第一中继终端的中继状态,从而得到所述第一信息:
1)接收第一中继终端通过无线资源控制(RRC)信令或媒体接入层控制单元(MAC CE)上报的中继状态;
2)基于终端之间的中继关联关系,获得所述第一中继终端的中继状态。
这里,中继关联关系是指中继终端与远端终端之间的关联关系,具体可以包括:中继终端的中继功能是否激活、中继终端是否与远端中继建立连接、中继终端是否正在进行中继业务传输等。基于上述中继关联关系,基站可以 确定第一中继终端的中继状态。
在发送所述第二信息之前,基站还可以根据所述第一中继终端的中继状态,确定是否释放第一中继终端的网络连接,从而生成用于指示是否释放第一中继终端的网络连接的所述第二信息。具体的,基站可以按照以下方式,确定是否释放第一中继终端的网络连接:
1)在所述第一中继终端处于第二中继状态时,确定保持所述第一中继终端的网络连接。
2)在所述第一中继终端处于第三中继状态时,确定释放所述第一中继终端的网络连接。
其中,其中,所述第二中继状态为第二状态集合中的一种状态,所述第三中继状态为第三状态集合中的一种状态;所述第二状态集合包括以下状态中的至少一种:中继功能已激活,但未建立与远端终端的连接;已建立与远端终端之间的连接,但未进行中继业务传输;正在进行中继业务传输;所述第三状态集合包括:所有的中继状态去除所述第二状态集合中的状态后的剩余中继状态。
例如,所述第二中继状态集合可以仅包括正在进行中继业务传输,此时第三状态集合包括:中继功能未激活;中继功能已激活,但未建立与远端终端的连接;以及,已建立与远端终端之间的连接,但未进行中继业务传输。这样,在第一中继终端处于“正在进行中继业务传输”的中继状态下时,确定保持所述第一中继终端的网络连接。而在第一中继终端处于“中继功能未激活”或“中继功能已激活,但未建立与远端终端的连接”或“已建立与远端终端之间的连接,但未进行中继业务传输”的中继状态下时,确定释放所述第一中继终端的网络连接。
又例如,所述第二状态集合可以仅包括:正在进行中继业务传输;以及,已建立与远端终端之间的连接,但未进行中继业务传输。此时第三状态集合包括:中继功能未激活;中继功能已激活,但未建立与远端终端的连接。这样,在第一中继终端处于“正在进行中继业务传输”或“已建立与远端终端之间的连接,但未进行中继业务传输”的中继状态下时,确定保持所述第一中继终端的网络连接。而在第一中继终端处于“中继功能未激活”或“中继功能 已激活,但未建立与远端终端的连接”的中继状态下时,确定释放所述第一中继终端的网络连接。
以上从基站侧介绍了本公开实施例的信息发送方法、接收方法,下面进一步从核心网侧进行描述。
请参照图6,本公开实施例提供了一种信息接收方法,应用于核心网设备,该核心网设备可以是核心网侧的一个或多个网元,如AMF或MME等。如图6所示,该方法包括:
步骤61,核心网设备接收基站发送的第一指示信息,所述第一指示信息用于指示第一中继终端的中继状态和/或指示是否释放第一中继终端的网络连接。
这里,所述第一指示信息可以包括用于指示第一中继终端的中继状态的第一信息,和/或,用于指示是否释放第一中继终端的网络连接的第二信息。其中,所述第一信息用于指示第一中继终端的中继状态,本公开实施例中,所述中继状态具体可以包括以下任意一种:
状态a:中继功能未激活。
状态b:中继功能已激活,但未建立与远端终端的连接。
状态c:已建立与远端终端之间的连接,但未进行中继业务传输。
状态d:正在进行中继业务传输。
所述第二信息用于指示是否请求释放第一中继终端的网络连接,即请求释放第一中继终端的网络连接,或者,请求保持第一中继终端的网络连接。所述网络连接具体可以包括所述第一中继终端建立的基站与核心网的连接、所述第一中继终端与基站的连接、以及所述第一中继终端与核心网的连接中的至少一者。
通过以上步骤,核心网设备可以获取第一中继终端的中继状态等信息,从而为核心网设备基于上述信息进行释放或保持第一中继终端的网络连接的决策提供了参考信息,这样可以在第一中继终端在存在中继业务传输时,减少或避免因为核心网不清楚中继终端的中继状态而导致的连接释放,进而可以提高中继传输的可靠性。
可选的,在上述步骤61之前,核心网设备可以向所述基站发送用于释放 所述第一中继终端的网络连接的释放消息。上述释放消息将触发基站发送所述第一信息和/或第二信息。具体的,核心网设备可以在第一中继终端的连接定时器超时时,发送上述释放消息。
可选的,在上述步骤61之前,核心网设备可以向所述基站发送用于指示上报所述第一中继终端的中继状态或中继状态变化的第一消息。例如,核心网设备可以在第一中继终端的连接定时器超时时,发送上述第一消息,用以获取第一中继终端的中继状态等信息。
进一步的,核心网设备可以根据第一中继终端的连接状态、中继能力以及是否授权作为中继终端,确定是否需要获取所述第一中继终端的中继状态。在需要获取所述第一中继终端的中继状态时,向所述基站发送上述第一消息。具体的,核心网设备可以在第一中继终端处于连接态,具备中继能力且被授权作为中继终端的情况下,确定需要获取所述第一中继终端的中继状态,否则,确定不需要获取所述第一中继终端的中继状态。例如,在不需要获取所述第一中继终端的中继状态时,核心网设备还可以向所述基站发送用于指示取消上报所述第一中继终端的中继状态或中继状态变化的第二消息。
在上述步骤61之后,核心网设备可以根据所述第一指示信息,确定是否发起对所述第一中继终端的网络连接的释放流程。
例如,在上述第一信息指示第一中继终端的中继状态为上述状态d时,确定不发起对所述第一中继终端的网络连接的释放流程;而在上述第一信息指示第一中继终端的中继状态为上述状态a、b或c时,确定发起对所述第一中继终端的网络连接的释放流程。
又例如,在上述第一信息指示第一中继终端的中继状态为上述状态c或d时,确定不发起对所述第一中继终端的网络连接的释放流程;而在上述第一信息指示第一中继终端的中继状态为上述状态a或b时,确定发起对所述第一中继终端的网络连接的释放流程。
当然,核心网设备还可以参考更多信息来确定是否发起释放流程,例如,还可以参考终端的连接定时器的超时情况等。例如,在连接定时器超时,且所述第一信息指示第一中继终端的中继状态为上述状态d时,确定不发起对所述第一中继终端的网络连接的释放流程;而在连接定时器超时,但上述第 一信息指示第一中继终端的中继状态为上述状态a、b或c时,确定发起对所述第一中继终端的网络连接的释放流程,等等。
以上分别从基站和核心网侧对本公开实施例的方法进行了说明。为了更好的理解以上内容,下面将通过更为具体的交互示例作进一步的说明。以下示例中,核心网设备(也称作核心网网元)以AMF为例进行说明。
示例1:
请参照图7,该示例1中,基站收到核心网网元发送的指示基站上报中继终端的中继状态变化的指示消息后,上报中继终端的中继状态。
步骤71:AMF基于中继终端的中继能力、是否被授权作为中继等信息,确定向基站发送用于请求上报中继终端的中继状态变化的指示消息。
步骤72:AMF发送用于请求上报中继终端的中继状态变化的指示消息,该指示消息为AMF发送给基站的消息。
步骤73:基站基于中继终端是否激活了中继功能,以及是否正在为远端终端提供中继服务,确定中继终端的中继状态。
步骤74:基站将中继终端的中继状态发送给AMF,例如,基站向AMF发送UE上下文修改响应(UEContextModificationResponse)消息,该消息携带有中继终端的中继状态。例如,可以在该消息中增加一个信元(Information Element,IE),如“中继状态(Relay State)”,用于指示中继终端的中继状态。具体的中继状态如上文所述,此处不再赘述。
示例2:
请参照图8,基站在中继终端的中继状态发生改变时,向核心网网元上报中继终端的中继状态。
步骤81:中继终端和基站间交互远端终端的链路信息,可以是以下场景:
1)远端终端的连接建立过程;
2)远端终端的连接释放过程。
从而基站可以获取中继终端的中继状态发生了变化,并能获取变化后的中继状态。
步骤82:基站确定中继终端的中继状态发生了改变。
步骤83:基站将中继终端的中继状态发送给AMF,例如,基站向AMF 发送UE上下文修改响应(UEContextModificationResponse)消息,该消息携带有中继终端的中继状态。例如,可以在该消息中增加一个IE,如“Relay State”,用于指示中继终端的中继状态。
示例3:
请参照图9,基站收到AMF发送的针对中继终端的上下文释放消息后,上报中继终端的中继状态。
步骤91:AMF基于中继终端自身的业务情况(无业务传输,定时器超时等),确定发起针对该中继终端的上下文释放流程。
步骤92:AMF向基站发送针对中继终端的UE上下文释放命令(UE Contex RELEASE COMMAND)。
步骤93:基站确定中继终端作为中继正在为远端终端提供中继服务。
步骤94:基站将中继终端的中继状态发送给AMF,例如,基站向AMF发送UE上下文修改响应(UEContextModificationResponse)消息,该消息携带有中继终端的中继状态。例如,可以在该消息中增加一个IE,如“Relay State”,用于指示中继终端的中继状态。。
步骤95:AMF基于基站上报的中继终端的中继状态,确定是否释放中继终端的连接和上下文。
以上各个示例中,基站进行中继终端中继状态上报的消息,具体可以是采用现有的UE上下文修改响应消息,需要说明的是,本公开实施例并不限于使用该消息承载中继状态。
下面给出采用现有的UE上下文修改响应消息承载中继状态的一个示例,该消息的方向是NG-RAN节点到AMF。例如,可以在UE上下文修改响应消息中增加一个IE,如“Relay State”,用于指示中继终端的中继状态。又例如,可以在UE上下文修改响应消息中增加一个IE,如“释放指示(Release Indication)”,用于指示是否释放第一中继终端的网络连接。
