为了便于更加清晰地理解本公开各实施例的技术方案,首先对本公开各实施例相关的一些技术内容进行介绍。
1、卫星网络及小区类型
由于卫星独特的地理位置,使其具有广覆盖、易于部署、信道稳定等优点,可以弥补地面网络的不足,地面网络与卫星网络的融合获得了广泛的关注。在卫星网络中,低轨卫星具有更低的传播时延、更多的可部署资源,是当前的研究重点。基于低轨卫星沿轨道高速移动的特性,规划了两种小区类型:准地表固定小区(quasi-earth fixed cell)和对地移动小区(earth moving cell)。
图1为相关技术提供的准地表固定小区和对地移动小区示意图,如图1所示,图1中的(a)部分示例了准地表固定小区,准地表固定小区指卫星通过调整天线角度,使波束在一段时间内固定不变的投影到地面的某个区域。参照图1,在T1时刻前区域A由卫星1服务,在T1时立刻变为由卫星2服务。图1中的(b)部分示例了对地移动小区,对地移动小区指卫星天线角度保持不变,随着卫星的移动,其波束的覆盖区域实时改变。
2、切换命令或条件切换命令配置信息
目前的切换流程中,当源基站做完切换决策或条件切换决策后,会向目标基站发送切换请求,目标基站进行准入控制,并向源基站发送切换请求确认消息,该切换请求确认消息中包含一个透传的容器,该容器包含的就是目标小区的相关配置信息,将要作为无线资源控制(Radio Resource Control,RRC)消息发送给终端。源基站接收到该消息后,向终端发送切换命令,将目标小区的相关配置信息发送给终端。
切换命令或条件切换命令中包含目标小区的公共配置信息,以及目标小区为终端分配的专用配置信息。其中目标小区的公共配置信息属于小区级别的配置信息,其中包含终端接入目标小区的必须的配置信息。为终端分配的专用配置信息是每个终端专用的资源,例如非竞争随机接入资源等。
切换命令或条件切换命令中公共配置信息与专用配置信息的划分:公共配置信息主要有ReconfigurationWithSync(同步重配置)中包含的spCellConfigCommon(小区公共配置)和t304(定时器)等。切换命令中的其它配置为perUE(每终端)的专用配置信息,例如目标小区为终端分配的非竞争随机接入资源等。
在NTN网络中,由于卫星不断沿轨道移动,覆盖地面固定区域的小区也 在不断变化。当服务地面某个区域的小区发生变化时,会面临短时间内大量终端需要进行切换或条件切换,从而造成很大的信令负载。本公开考虑到切换命令或条件切换命令中有一部分是公共的信息,例如服务小区的公共配置、条件切换的门限等,这部分公共的信息可以从切换命令/条件切换命令中拿出来,通过广播的方式发送给终端,从而减轻信令负载。
图2为本公开实施例提供的切换命令传输方法的流程示意图之一,该方法可应用于终端,如图2所示,该方法包括如下步骤:
步骤200、根据第一信息,获取网络设备广播的公共配置信息;公共配置信息包括用于切换或者条件切换的目标小区或候选小区的公共配置信息。
具体地,本公开实施例中,网络设备(例如基站)可以将原本在切换命令或条件切换命令中携带的公共配置信息,通过广播消息的形式发送给终端,以便在短时间内大量终端需要进行切换或条件切换的场景中,能够减轻信令负载。
终端可以根据预配置的或者网络设备发送的第一信息,去监听和获取网络设备广播的公共配置信息。并结合网络设备通过专用信令发送给终端的切换命令或条件切换命令中携带的专用配置信息,得到完整的用于切换或条件切换的配置信息。
需要说明的是,本公开各实施例虽然以NTN网络场景为例进行说明,但本领域技术人员应当理解,本公开各实施例的技术方案并不局限于该场景,其他存在类似问题(在短时间内大量终端需要进行切换或条件切换)的场景同样也可以适用。
本公开实施例提供的切换命令传输方法,网络设备可以通过广播消息,将原本在切换命令或条件切换命令中携带的公共配置信息,广播给终端,从而在短时间内大量终端需要进行切换或条件切换的场景中,能够有效减轻信令负载。
在一些实施例中,第一信息包括以下一项或多项:
(1)广播时间信息,广播时间信息用于指示网络设备广播公共配置信息的时间信息。
具体地,一种实施方式中,终端可以根据该广播时间信息,确定当前服务小区广播公共配置信息的一些时间参数,如开始时间、结束时间、持续时间、周期、偏移量等等,从而只需要在一定的时间范围内,监听当前服务小区广播的公共配置信息即可,可以有效减少监听能耗。
在一些实施例中,广播时间信息可以包括以下一项或多项:
(1-1)网络设备广播公共配置信息的开始时间信息。
例如,该开始时间信息可以指示网络设备开始广播公共配置信息的绝对时间。
(1-2)网络设备广播公共配置信息的结束时间信息。
例如,该结束时间信息可以指示网络设备结束广播公共配置信息的绝对时间。
(1-3)网络设备广播公共配置信息的持续时间信息。
例如,该持续时间信息可以与上述开始时间信息或者上述结束时间信息配合使用,指示出网络设备广播公共配置信息的时间范围。或者,该持续时间信息可以与小区的停止服务时间(对于准地表固定小区)配合使用,表示小区停止服务前多久开始广播公共配置信息。
(1-4)当前服务小区的停止服务时间信息。
例如,对于准地表固定小区,广播时间信息可以包括当前服务小区的停止服务时间信息,该信息可以与上述开始时间信息配合使用,表示广播时间一直持续到小区停止服务为止。或者,当前服务小区的停止服务时间信息也可以与上述持续时间信息配合使用,表示小区停止服务前多久开始广播公共配置信息。
(1-5)第一周期,第一周期表示网络设备广播公共配置信息的持续时间内,公共配置信息的广播周期。
图3为本公开实施例提供的网络广播系统消息的不同时间特征示意图,如图3中的(a)、(b)、(c)三种广播形式,其中(a)表示网络持续性周期广播,(b)表示小区在停止服务时间前一段时间内周期性广播,(c)表示网络在周期的时段(持续时间duration)内,周期性广播,也即(c)中持续时 间有一定的周期,每个持续时间范围内网络广播公共配置信息也有一定的周期。(c)与(a)的区别在于(c)中网络不是持续性以一个相同的周期广播公共配置信息,而只是在每个持续时间内周期性广播公共配置信息。
相比(a)中的持续性周期广播形式,(b)和(c)两种广播形式可以减少网络广播的无线资源消耗以及终端的监听能耗。
以图3所示的广播形式为例,第一周期可以指的是(b)和(c)中,单个持续时间内,网络广播公共配置信息的周期(即网络以什么样的频率广播公共配置信息)。第一周期的单位可以是时隙或者子帧等。
(1-6)第一偏移量,第一偏移量表示网络设备广播公共配置信息的持续时间内,公共配置信息的开始广播时间相对于参考系统帧号的偏移量。
以图3所示的广播形式为例,第一偏移量可以指的是(b)和(c)中,单个持续时间内,网络第一次广播公共配置信息的时间相对于参考系统帧号(System Frame Number,SFN)的偏移量。其中参考SFN可以灵活设置,具体不做限制。
(1-7)第二周期,第二周期表示网络设备广播公共配置信息的持续时间所对应的周期。
以图3所示的广播形式为例,第二周期可以指的是(c)中持续时间的周期。第二周期的单位可以是秒或其他时间单位。
(1-8)第三周期,第三周期表示网络设备广播公共配置信息的周期。
以图3所示的广播形式为例,第三周期可以指的是(a)中网络持续地以某个周期进行广播。
(1-9)第二偏移量,第二偏移量表示网络设备周期性广播公共配置信息的开始时间相对于参考系统帧号的偏移量。
以图3所示的广播形式为例,第二偏移量可以指的是(a)中,网络第一次广播公共配置信息的时间相对于参考SFN的偏移量。
在一些实施例中,上述广播时间信息的获取方式包括以下一项或多项:
(1-a)读取网络设备广播的第一系统信息,第一系统信息中包含广播时间信息。
例如,第一系统信息可以是系统信息块(System Information Block,SIB)1,SIB19或者新定义的SIB等,网络设备可以在这些SIB中包含广播时间信息,从而终端可以读取系统信息获取到网络设备广播公共配置信息的时间信息。
(1-b)接收网络设备发送的第一信令,第一信令中包含广播时间信息。
例如,第一信令可以是网络设备向终端发送信息的专用信令。一种可能的实现方式中,比如在条件切换过程中,网络提前向终端发送条件切换配置时,可以将网络广播公共配置信息的时间信息发送给终端,即通过RRC重配置消息携带广播时间信息。
(1-c)获取预配置的广播时间信息。
广播时间信息也可以是预配置给终端的,例如对于某个固定的卫星星座(卫星星座可以简单理解为一系列具有相关关系的卫星,一个卫星星座可能包含多条轨道,每条轨道上有多颗卫星)来说,该广播时间信息可以设置为固定值,可以预配置给终端。
(2)第一监听配置信息,第一监听配置信息用于监听并获取网络设备广播的公共配置信息。
具体地,一种实施方式中,网络可以为终端配置第一监听配置信息,该第一监听配置信息可用于终端监听网络广播的公共配置信息,并从中读取公共配置信息。
在一些实施例中,第一监听配置信息可以包括第一物理下行控制信道(Physical Downlink Control Channel,PDCCH)配置信息、第一无线网络临时标识(Radio Network Temporary Identity,RNTI)中的一项或多项。
其中,第一PDCCH配置信息可用于监听公共配置信息,比如可以包括网络广播公共配置信息的信道的资源配置。第一RNTI可用于解析公共配置信息。
(3)第二监听配置信息,第二监听配置信息用于监听并获取第一指示信息,第一指示信息用于指示终端开始监听网络设备广播的公共配置信息。
具体地,网络设备可以向终端发送第一指示信息,用于指示终端开始监 听网络广播的公共配置信息。终端可以在获取到该第一指示信息后,才开始监听并读取公共配置信息,或者等到下一个系统信息窗口(SI window)再开始读取公共配置信息,可以有效减少终端能耗。
在网络设备向终端发送第一指示信息的情况下,网络可以为终端配置第二监听配置信息,该第二监听配置信息可用于终端监听并获取第一指示信息。
在一些实施例中,第二监听配置信息可以包括第二PDCCH配置信息、第二RNTI中的一项或多项。
其中,第二PDCCH配置信息可用于监听第一指示信息,比如可以包括网络发送第一指示信息的信道的资源配置。第二RNTI可用于解析第一指示信息。
在一些实施例中,根据第一信息,获取网络设备广播的公共配置信息,包括:
根据第二监听配置信息,监听寻呼消息或下行控制信息DCI,获取寻呼消息或DCI中包含的第一指示信息;
根据第一指示信息,监听并获取公共配置信息。
具体地,在网络设备向终端发送第一指示信息的情况下,终端可以根据第二监听配置信息,例如第二PDCCH配置信息、第二RNTI等,监听寻呼消息或下行控制信息(Downlink Control Information,DCI)并读取到第一指示信息。
一种实施方式中,网络可以通过RRC消息或者DCI的形式指示终端开始监听网络广播的公共配置信息。RRC消息指寻呼消息,可以在寻呼消息中添加新的寻呼原因,指示终端开始监听公共配置信息。DCI可以指DCI 1_0中的短消息,利用一个比特指示终端开始监听公共配置信息。
终端通过监听寻呼消息或DCI,读取到网络指示终端开始监听目标/候选小区的公共配置信息后,终端开始监听并读取公共配置信息,或者等到下一个SI window开始读取。
(4)配置指示信息,配置指示信息用于指示网络设备通过专用信令发送的切换命令/条件切换命令中的专用配置信息与公共配置信息之间的对应关 系。
具体地,通过广播消息发送原本在切换命令/条件切换命令中携带的公共配置信息,如果广播的公共配置信息中包含多个小区的公共配置信息,当网络后续为终端配置切换命令的专用配置信息部分时,由于切换命令中的专用配置信息不包含识别小区的信息,终端将无法识别目标小区,也无法判断网络配置的专用配置信息对应的是哪一套公共配置信息,可能会造成切换的失败。
为此,本公开实施例中,网络设备可以向终端发送配置指示信息,指示网络设备通过专用信令发送的切换命令中的专用配置信息与网络设备广播的公共配置信息之间的对应关系,从而终端可以根据该配置指示信息,获知网络通过专用信令配置的专用配置信息对应的是哪个公共配置信息。
在一些实施例中,配置指示信息可以包括专用配置信息对应的物理小区标识(Physical Cell Identifier,PCI)、专用配置信息对应的频点、专用配置信息对应的索引号中的一项或多项。
在一些实施例中,网络设备广播的公共配置信息中可以携带公共配置信息对应的PCI、公共配置信息对应的频点、公共配置信息对应的索引号中的一项或多项。
例如,当服务小区广播的目标/候选小区的PCI均不相同,则公共配置信息中可以不携带频点信息,配置指示信息也可以仅包括PCI信息。反之如果服务小区广播的目标/候选小区的频点均不相同,则配置指示信息可以不包括PCI。或者只有频点相同的小区才需要结合指示PCI。
例如,公共配置信息的索引号可以是显式指示或者隐式指示的。显式指示可以是通过添加比特进行明确标识;隐式指示可以是,认为公共配置信息中每个小区的公共配置信息分别对应一个条目,第一个条目的索引号为1,第二个条目的索引号为2,以此类推。
在一些实施例中,根据第一信息,获取网络设备广播的公共配置信息,包括:
根据配置指示信息,从网络设备广播的公共配置信息中,确定第一专用 配置信息所对应的第一公共配置信息;或者,
根据配置指示信息指示的第一专用配置信息对应的PCI和/或频点,搜索到第一专用配置信息对应的第一小区后,通过读取第一小区广播的系统信息,获取第一专用配置信息所对应的第一公共配置信息。
具体地,对于切换来说,第一专用配置信息是网络通过专用信令发送的切换命令中的专用配置信息。对于条件切换来说,第一专用配置信息是终端通过评估执行条件,判断满足执行条件的专用配置信息,第一公共配置信息指的是与第一专用配置信息相对应的公共配置信息。相对应的一组配置信息(第一专用配置信息和第一公共配置信息)可以组成完整的切换命令,用于切换或条件切换。
一种实施方式中,终端可以获取到网络设备广播的公共配置信息,则终端可以根据配置指示信息的指示,从网络设备广播的公共配置信息中,确定通过专用信令接收到的一个或多个专用配置信息分别对应的公共配置信息。
在一些实施例中,根据配置指示信息,从网络设备广播的公共配置信息中,确定第一专用配置信息所对应的第一公共配置信息,包括以下一项或多项:
根据配置指示信息指示的第一专用配置信息对应的PCI和/或频点,以及公共配置信息中携带的PCI和/或频点,从公共配置信息中确定第一专用配置信息所对应的第一公共配置信息;或者,
根据配置指示信息指示的第一专用配置信息对应的索引号,以及公共配置信息对应的索引号,从公共配置信息中确定第一专用配置信息所对应的第一公共配置信息。
例如,当前服务小区广播的目标/候选小区公共配置信息中携带对应小区的PCI和/或频点,网络通过专用信令发送专用配置信息,并发送配置指示信息,配置指示信息中携带专用配置信息对应的PCI和/或频点,与第一专用配置信息的PCI和/或频点对应相同的公共配置信息即为第一公共配置信息。
例如,网络通过专用信令发送专用配置信息,并发送配置指示信息,配置指示信息中携带专用配置信息对应的索引号,该索引号可以指示某个专用 配置信息对应当前服务小区广播的目标/候选小区公共配置信息中的哪个小区公共配置信息(对应的一组专用配置信息和公共配置信息的索引号相同)。
一种实施方式中,在终端没有成功获取当前服务小区广播的目标小区的公共配置信息时,由于切换命令中的专用配置信息不包含识别小区的信息,终端将无法确定目标小区,可能造成切换失败。
在这种情况下,终端可以根据配置指示信息指示的PCI和/或频点信息,在没有成功获取到源服务小区广播的目标/候选小区的公共配置信息时,可以基于PCI和/或频点信息搜索目标/候选小区,从目标/候选小区广播的系统信息中获取相应小区的公共配置信息,从而接入目标小区完成切换。
以获取目标小区的公共配置信息为例,终端可以基于配置指示信息指示的PCI和/或频点信息,搜索目标小区或在执行切换时搜索目标小区,读取目标小区的系统信息,从而获取目标小区的公共配置信息,完成切换。
在一些实施例中,配置指示信息的获取方式包括:
接收网络设备发送的专用配置信息,专用配置信息中包含配置指示信息;或者,
接收网络设备发送的配置指示信息,配置指示信息与专用配置信息相关联。
具体地,一种可能的实现方式中,网络设备可以将配置指示信息包含在专用配置信息中发送给终端。或者包含在切换命令中发送给终端。
一种可能的实现方式中,网络设备可以不将配置指示信息包含在专用配置信息中,而是与专用配置信息作为并列的信息发送给终端,但需要将配置指示信息与专用配置信息相关联,以便指示每个专用配置信息所对应的PCI、频点、索引号等。
在一些实施例中,该方法还包括:
向网络设备发送终端能力信息,终端能力信息用于指示终端是否支持从广播的系统信息中获取公共配置信息。
具体地,终端可以向网络上报自己是否支持从广播的系统信息中获取目标/候选小区的公共配置信息的能力,从而网络可以根据终端能力发送相应的 切换命令/条件切换命令。
例如,对于不支持该能力的终端,网络为终端配置切换命令/条件切换命令时,可以通过专用信令发送完整的命令。
对于支持该能力的终端,如果网络没有广播目标/候选小区的公共配置信息,则为终端配置切换命令/条件切换命令时,可以通过专用信令发送完整的命令。如果网络广播了目标/候选小区的公共配置信息,为终端配置切换命令/条件切换命令时,专用信令中可不包含目标/候选小区的公共配置信息。
图4为本公开实施例提供的切换命令传输方法的流程示意图之二,该方法可应用于网络设备(例如基站),如图4所示,该方法包括如下步骤:
步骤400、确定第一信息,第一信息用于终端获取网络设备广播的公共配置信息;公共配置信息包括用于切换或者条件切换的目标小区或候选小区的公共配置信息。
步骤401、发送第一信息。
具体地,本公开实施例中,网络设备(例如基站)可以将原本在切换命令或条件切换命令中携带的公共配置信息,通过广播消息的形式发送给终端,以便在短时间内大量终端需要进行切换或条件切换的场景中,能够减轻信令负载。
在这种情况下,网络设备可以向终端发送第一信息,终端可以根据该第一信息去监听和获取网络设备广播的公共配置信息,并结合网络设备通过专用信令发送给终端的切换命令或条件切换命令中携带的专用配置信息,得到完整的用于切换或条件切换的配置信息。
在一些实施例中,第一信息包括以下一项或多项:
(1)广播时间信息,广播时间信息用于指示网络设备广播公共配置信息的时间信息。
具体地,一种实施方式中,网络设备可以向终端发送广播时间信息,终端可以根据该广播时间信息,确定当前服务小区广播公共配置信息的一些时间参数,如开始时间、结束时间、持续时间、周期、偏移量等等,从而只需要在一定的时间范围内,监听当前服务小区广播的公共配置信息即可,可以 有效减少监听能耗。
在一些实施例中,广播时间信息可以包括以下一项或多项:
(1-1)网络设备广播公共配置信息的开始时间信息。
例如,该开始时间信息可以指示网络设备开始广播公共配置信息的绝对时间。
(1-2)网络设备广播公共配置信息的结束时间信息。
例如,该结束时间信息可以指示网络设备结束广播公共配置信息的绝对时间。
(1-3)网络设备广播公共配置信息的持续时间信息。
例如,该持续时间信息可以与上述开始时间信息或者上述结束时间信息配合使用,指示出网络设备广播公共配置信息的时间范围。或者,该持续时间信息可以与小区的停止服务时间(对于准地表固定小区)配合使用,表示小区停止服务前多久开始广播公共配置信息。
(1-4)当前服务小区的停止服务时间信息。
例如,对于准地表固定小区,广播时间信息可以包括当前服务小区的停止服务时间信息,该信息可以与上述开始时间信息配合使用,表示广播时间一直持续到小区停止服务为止。或者,当前服务小区的停止服务时间信息也可以与上述持续时间信息配合使用,表示小区停止服务前多久开始广播公共配置信息。
(1-5)第一周期,第一周期表示网络设备广播公共配置信息的持续时间内,公共配置信息的广播周期。
以图3所示的广播形式为例,第一周期可以指的是(b)和(c)中,单个持续时间内,网络广播公共配置信息的周期(即网络以什么样的频率广播公共配置信息)。第一周期的单位可以是时隙或者子帧等。
(1-6)第一偏移量,第一偏移量表示网络设备广播公共配置信息的持续时间内,公共配置信息的开始广播时间相对于参考系统帧号的偏移量。
以图3所示的广播形式为例,第一偏移量可以指的是(b)和(c)中,单个持续时间内,网络第一次广播公共配置信息的时间相对于参考SFN的偏 移量。
(1-7)第二周期,第二周期表示网络设备广播公共配置信息的持续时间所对应的周期。
以图3所示的广播形式为例,第二周期可以指的是(c)中持续时间的周期。第二周期的单位可以是秒或其他时间单位。
(1-8)第三周期,第三周期表示网络设备广播公共配置信息的周期。
以图3所示的广播形式为例,第三周期可以指的是(a)中网络持续地以某个周期进行广播。
(1-9)第二偏移量,第二偏移量表示网络设备周期性广播公共配置信息的开始时间相对于参考系统帧号的偏移量。
以图3所示的广播形式为例,第二偏移量可以指的是(a)中,网络第一次广播公共配置信息的时间相对于参考SFN的偏移量。
在一些实施例中,上述广播时间信息的发送方式包括以下一项或多项:
(1-a)广播第一系统信息,第一系统信息中包含广播时间信息。
例如,第一系统信息可以是SIB1,SIB19或者新定义的SIB等,网络设备可以在这些SIB中包含广播时间信息,从而终端可以读取系统信息获取到网络设备广播公共配置信息的时间信息。
(1-b)向终端发送第一信令,第一信令中包含广播时间信息。
例如,第一信令可以是网络设备向终端发送信息的专用信令。一种可能的实现方式中,比如在条件切换过程中,网络提前向终端发送条件切换配置时,可以将网络广播公共配置信息的时间信息发送给终端,即通过RRC重配置消息携带广播时间信息。
(2)第一监听配置信息,第一监听配置信息用于终端监听并获取网络设备广播的公共配置信息。
具体地,一种实施方式中,网络可以为终端配置第一监听配置信息,该第一监听配置信息可用于终端监听网络广播的公共配置信息,并从中读取公共配置信息。
在一些实施例中,第一监听配置信息可以包括第一PDCCH配置信息、 第一RNTI中的一项或多项。
其中,第一PDCCH配置信息可用于监听公共配置信息,比如可以包括网络广播公共配置信息的信道的资源配置。第一RNTI可用于解析公共配置信息。
(3)第二监听配置信息,第二监听配置信息用于终端监听并获取第一指示信息,第一指示信息用于指示终端开始监听网络设备广播的公共配置信息。
具体地,网络设备可以向终端发送第一指示信息,用于指示终端开始监听网络广播的公共配置信息。终端可以在获取到该第一指示信息后,才开始监听并读取公共配置信息,或者等到下一个SI window再开始读取公共配置信息,可以有效减少终端能耗。
在网络设备向终端发送第一指示信息的情况下,网络可以为终端配置第二监听配置信息,该第二监听配置信息可用于终端监听并获取第一指示信息。
在一些实施例中,第二监听配置信息可以包括第二PDCCH配置信息、第二RNTI中的一项或多项。

在一些实施例中,该方法还包括:
向终端发送寻呼消息或下行控制信息DCI,寻呼消息或DCI中包含第一指示信息。
具体地,在网络设备向终端发送第一指示信息的情况下,终端可以根据第二监听配置信息,例如第二PDCCH配置信息、第二RNTI等,监听寻呼消息或DCI并读取到第一指示信息。
一种实施方式中,网络可以通过RRC消息或者DCI的形式指示终端开始监听网络广播的公共配置信息。RRC消息指寻呼消息,可以在寻呼消息中添加新的寻呼原因,指示终端开始监听公共配置信息。DCI可以指DCI 1_0中的短消息,利用一个比特指示终端开始监听公共配置信息。
终端通过监听寻呼消息或DCI,读取到网络指示终端开始监听目标/候选 小区的公共配置信息后,终端开始监听并读取公共配置信息,或者等到下一个SI window开始读取。
(4)配置指示信息,配置指示信息用于指示网络设备通过专用信令发送的切换命令/条件切换命令中的专用配置信息与公共配置信息之间的对应关系。
具体地,通过广播消息发送原本在切换命令/条件切换命令中携带的公共配置信息,如果广播的公共配置信息中包含多个小区的公共配置信息,当网络后续为终端配置切换命令的专用配置信息部分时,由于切换命令中的专用配置信息不包含识别小区的信息,终端将无法识别目标小区,也无法判断网络配置的专用配置信息对应的是哪一套公共配置信息,可能会造成切换的失败。
为此,本公开实施例中,网络设备可以向终端发送配置指示信息,指示网络设备通过专用信令发送的切换命令中的专用配置信息与网络设备广播的公共配置信息之间的对应关系,从而终端可以根据该配置指示信息,获知网络通过专用信令配置的专用配置信息对应的是哪个公共配置信息。
在一些实施例中,配置指示信息可以包括专用配置信息对应的PCI、专用配置信息对应的频点、专用配置信息对应的索引号中的一项或多项。
在一些实施例中,网络设备广播的公共配置信息中可以携带公共配置信息对应的PCI、公共配置信息对应的频点、公共配置信息对应的索引号中的一项或多项。
例如,当服务小区广播的目标/候选小区的PCI均不相同,则公共配置信息中可以不携带频点信息,配置指示信息也可以仅包括PCI信息。反之如果服务小区广播的目标/候选小区的频点均不相同,则配置指示信息可以不包括PCI。或者只有频点相同的小区才需要结合指示PCI。
例如,公共配置信息的索引号可以是显式指示或者隐式指示的。显式指示可以是通过添加比特进行明确标识;隐式指示可以是,认为公共配置信息中每个小区的公共配置信息分别对应一个条目,第一个条目的索引号为1,第二个条目的索引号为2,以此类推。
在一些实施例中,配置指示信息的发送方式包括:
向终端发送专用配置信息,专用配置信息中包含配置指示信息;或者,
向终端发送配置指示信息,配置指示信息与专用配置信息相关联。
具体地,一种可能的实现方式中,网络设备可以将配置指示信息包含在专用配置信息中发送给终端。或者包含在切换命令中发送给终端。
一种可能的实现方式中,网络设备可以不将配置指示信息包含在专用配置信息中,而是与专用配置信息作为并列的信息发送给终端,但需要将配置指示信息与专用配置信息相关联,以便指示每个专用配置信息所对应的PCI、频点、索引号等。
在一些实施例中,向终端发送配置指示信息之前,该方法还包括以下一项或多项:
(1)生成配置指示信息并发送给目标小区或候选小区。
例如,配置指示信息可以是源服务小区生成的,源服务小区生成配置指示信息之后,将该配置指示信息发送给目标/候选小区(例如通过切换请求消息)。目标/候选小区在生成切换命令时,将配置指示信息包含在切换命令中,并发送给源服务小区。
(2)接收目标小区或候选小区发送的切换命令,切换命令中包含目标小区或候选小区生成的配置指示信息。
例如,配置指示信息可以是目标/候选小区生成的,目标/候选小区在生成切换命令时,将配置指示信息包含在切换命令中,并发送给源服务小区。
(3)接收目标小区或候选小区发送的切换命令后,将生成的配置指示信息包含在目标小区或候选小区发送的切换命令中。
例如,配置指示信息可以是源服务小区在接收到目标小区或候选小区发送的切换命令后,将源服务小区生成的配置指示信息包含在切换命令中,发送给终端。
(4)接收目标小区或候选小区发送的切换命令后,将生成的配置指示信息与切换命令中的专用配置信息相关联。
例如,配置指示信息可以是源服务小区在接收到目标小区或候选小区发 送的切换命令后,将生成的配置指示信息与切换命令中的专用配置信息相关联,并将配置指示信息与切换命令并列发送给终端。
