技术领域
本公开涉及移动通信技术领域，具体涉及一种切换方法、信息交互方法、设备及计算机可读存储介质。
背景技术
在第五代移动通信(5G)非独立组网中，以长期演进(LTE)基站为主站，新空口(NR)基站为辅站进行组网，能够支持LTE-NR多连接服务的服务。本文中所述的多连接包括双连接以及三条或更多的连接。在5G非独立组网的场景下，由于NR的数据速率比LTE高很多，在切换过程(具体可以是多连接下的切换或单连接下的切换)中，如果作为候选基站的多个LTE基站的信号质量相当，通常应为数据速率需求较高的终端(UE)优先选择支持LTE-NR多连接的LTE基站作为候选基站，以保证终端在候选基站下还能够获得较高的数据速率。
按照相关技术的切换机制，在切换开始时，源基站通常不知道候选基站是否可为终端提供LTE-NR多连接的服务，在选择目标基站时无法确保选到可以支持LTE-NR多连接的候选基站，从而无法满足有着高速率服务需求的UE的个性化服务要求。
本专利提出了一种在源和候选基站之间交互LTE-NR多连接能力的方案，从而帮助UE切换到符合需求的目标基站上。

为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。在下面的描述中，提供诸如具体的配置和组件的特定细节仅仅是为了帮助全面理解本公开的实施例。因此，本领域技术人员应该清楚，可以对这里描述的实施例进行各种改变和修改而不脱离本公开的范围和精神。另外，为了清楚和简洁，省略了对已知功能和构造的描述。
应理解，说明书通篇中提到的“一个实施例”或“一实施例”意味着与实施 例有关的特定特征、结构或特性包括在本公开的至少一个实施例中。因此，在整个说明书各处出现的“在一个实施例中”或“在一实施例中”未必一定指相同的实施例。此外，这些特定的特征、结构或特性可以任意适合的方式结合在一个或多个实施例中。
在本公开的各种实施例中，应理解，下述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本公开实施例的实施过程构成任何限定。
本公开实施例要解决的技术问题是提供一种切换方法、信息交互方法、设备及计算机可读存储介质，在切换过程中帮助第一网络设备选择能够提供LTE-NR多连接的第二网络设备。
本公开实施例提供的切换方法，可以应用于5G非独立组网的场景中。这里，所述的5G非独立组网是指以LTE基站为主站，NR基站为辅站的组网。该组网可以支持LTE-NR多连接的服务。这里，所述的多连接包括双连接以及三条或更多的连接。在LTE-NR多连接中，通常由LTE基站作为主站，NR基站作为辅站。当然，本公开实施例的切换方法，也可以应用于其他组网模式下的多连接场景，如仅包括一种类型的基站(如全部为NR基站)的组网模式，或者包括多种其他类型的基站的组网。
为描述方便，以下将以网络设备进行说明。在本公开实施例中，网络设备的形式不限，可以是宏基站(Macro Base Station)、微基站(Pico Base Station)、Node B(3G移动基站的称呼)、增强型基站(eNB)、家庭增强型基站(Femto eNB或Home eNode B或Home eNB或HeNB)、中继站、接入点、远端射频模块(Remote Radio Unit，RRU)、射频拉远头(Remote Radio Head，RRH)、NR基站/gNB(5G移动基站的称呼)、5G移动通信系统中的网络侧节点，如中央单元(Central Unit，CU)和分布式单元(Distributed Unit，DU)等。终端可以是移动电话(或手机)，或者其他能够发送或接收无线信号的设备，包括用户设备(UE)、个人数字助理(PDA)、无线调制解调器、无线通信装置、手持装置、膝上型计算机、无绳电话、无线本地回路(WLL)站、能够将移动信号转换为WiFi信号的客户终端(Customer Premise Equipment，CPE)或移动智能热点、智能家电、或其他不通过人的操作就能自发与移动通信网络 通信的设备等。另外，本文中术语“系统”和“网络”在本文中常可互换使用。
如图1所示，本公开实施例提供的切换方法，包括：
步骤11，第一网络设备向至少一个候选第二网络设备发送针对一终端的切换请求消息。
这里，第一网络设备可以是当前为终端服务的网络设备，如源基站；候选第二网络设备可以是切换的候选目标基站。第一网络设备在需要切换为某个终端服务的网络设备时，向至少一个候选第二网络设备(例如为LTE基站)发送切换请求(Handover Reques)消息，请求将该终端切换至该候选第二网络设备。
步骤12，第一网络设备接收所述至少一个候选第二网络设备发送的切换请求确认消息，所述切换请求确认消息携带有所述候选第二网络设备的多连接能力信息。
这里，所述多连接能力信息可以是用于指示候选第二网络设备是否支持多连接的指示信息，此时，该指示信息可以采用1比特长度的字段来表征。作为另一种实现方式，所述多连接能力信息还可以包括能够与所述候选第二网络设备进行多连接的小区的信息，此时，若所述多连接能力信息指示的能够与所述候选第二网络设备进行多连接的小区为空，则表示候选第二网络设备不支持多连接能力，若非空，则表示支持多连接能力，且同时指示了能够与所述候选第二网络设备进行多连接的小区列表。
这里，候选第二网络设备在接收到上述切换请求消息后，进行接纳控制处理，如允许该终端切换至本候选第二网络设备，则向第一网络设备发送一切换请求确认(Handover Request Acknowledge)消息。本公开实施例中，在该切换请求确认消息中携带候选第二网络设备的多连接能力信息，所述多连接能力信息通常可以包括本候选第二网络设备是否能否提供多连接服务以及能够与候选第二网络设备进行多连接的小区的信息。
本公开实施例中，候选第二网络设备能否提供多连接服务，通常由候选第二网络设备是否具备支持多连接能力，并且在支持多连接能力时，是否已添加有辅站等因素来决定。例如，仅在候选第二网络设备具备支持多连接能力，且已添加有辅站的情况下，候选第二网络设备能够提供多连接服务，否 则，候选第二网络设备不能够提供多连接服务。
在具体实现时，可以仅在切换请求确认消息中携带能够与所述候选第二网络设备进行多连接的小区的信息。例如，若携带的小区为空时，表示候选第二网络设备不能提供多连接服务；在携带的小区非空时，表示候选第二网络设备支持多连接服务，且多连接服务中的辅小区包括切换请求确认消息中携带的小区。所述切换请求确认消息携带的多连接能力信息具体可以为：能够与所述候选第二网络设备进行多连接的小区的小区个数或小区ID，或者为一位图bitmap，所述位图中的比特位一一对应于所述切换请求消息中携带的小区，且比特位的不同取值代表对应小区是否能够与候选第二网络设备进行多连接。也就是说，可以在切换请求确认消息中携带具体的小区个数或小区ID，或者，用位图(bitmap)的方式指示候选第二网络设备与切换请求消息中的小区集合中的各个小区是否可以进行多连接，例如，某个小区对应的比特位为取值1时表示可以，0时表示不可以。当然，也可以某个小区对应的比特位为取值0时表示可以，1时表示不可以。
通过以上步骤，本公开实施例可以使得第一网络设备获得各个候选第二网络设备的多连接能力信息，以进行后续的切换。例如，在上述步骤12之后，本公开实施例还可以包括以下步骤：第一网络设备根据各个候选第二网络设备的多连接能力信息进行切换。
这里，第一网络设备可以根据各个候选第二网络设备返回的切换请求确认消息，获知各个候选第二网络设备能否提供多连接服务，以及，在候选第二网络设备能够提供多连接服务时，能够与候选第二网络设备进行多连接的小区的信息。第一网络设备可以根据各个候选第二网络设备返回的切换请求确认消息，在本地维护各个候选第二网络设备的多连接能力信息。下表1给出了源基站通过表格方式维护多连接能力信息的一个示例。每一行中的第一列表示某个LTE基站(候选第二网络设备)，第二列则表示能够与该LTE基站进行多连接的小区的列表。
基站 LTE-NR多连接能力信息
LTE基站1 NR小区1，NR小区2
LTE基站2 NR小区3
LTE基站3 NR小区4，NR小区5
… …
表1
因此，第一网络设备可以根据各个候选第二网络设备的多连接能力信息，优先选择能够提供多连接服务的候选第二网络设备作为切换的第二网络设备(如目标基站)，将终端切换至第二网络设备。
通过以上步骤，本公开实施例的第一网络设备可以在切换过程中获取候选第二网络设备的多连接能力信息，从而使得第一网络设备可以据此选择能够提供多连接服务的候选第二网络设备作为第二网络设备，可以满足高速率服务需求的终端的切换要求，改善了终端的网络体验。
本公开实施例中，在上述步骤11之前，第一网络设备还可能接收到终端发送的测量报告，所述测量报告可以包括所述终端测量得到的小区及其小区质量信息，具体地，小区质量信息可以用参考信号接收功率(RSRP)、参考信号接收质量(RSRQ)、信号与干扰加噪声比(SINR)等参数来表征。在上述步骤11中，所述第一网络设备可以进一步在所述切换请求消息中携带小区集合，所述NR小区集合包括所述终端测量得到的小区中的全部小区或部分小区，其中，所述部分小区是基于所述小区的小区质量信息选择出的，例如，选择出预设数量的小区质量排序靠前的小区或者选择出小区质量满足预设门限的小区。这样，候选第二网络设备在接收到上述切换请求消息后，可以确认是否能够与所述NR小区集合中的小区进行多连接(即所述小区集合中的小区能否作为辅小区)，并将能够进行多连接的小区作为能够与本候选第二网络设备进行多连接的小区。具体的，候选第二网络设备可以通过辅小区添加操作，来确认是否能够与所述小区集合中的小区进行多连接。
以上实现方式中，是在切换过程中获取候选第二网络设备的多连接能力信息。作为一种替换或附加的实现方式，本公开实施例中，网络设备之间可以通过网络设备之间的接口(如X2接口或Xn接口等)，获取各自的双连接能力信息。
例如，第一网络设备在建立与相邻网络设备之间的网络设备间接口或者在更新网络设备间接口配置时，获取相邻网络设备的多连接能力信息和/或将 本第一网络设备的多连接能力信息发送给相邻网络设备。
具体地，请参照图2，第一网络设备可以通过向相邻网络设备发送多连接能力请求消息，并接收相邻网络设备返回的多连接能力反馈消息，该反馈消息中携带有相邻网络设备的多连接能力信息，从而获得相邻网络设备的多连接能力信息。
请参照图3，作为另一种实现，第一网络设备可以通过多连接能力交互消息，将自身的多连接能力信息发送给相邻网络设备，以及，接收相邻网络设备发送的双连接能力交互消息，获得相邻网络设备的多连接能力信息。
在获得相邻网络设备的多连接能力信息后，第一网络设备在切换过程中，可以根据终端的测量报告，确定切换的候选第二网络设备，并根据各个候选第二网络设备的多连接能力信息，选择能够提供多连接服务的候选第二网络设备作为第二网络设备，并发起切换。
以上从第一网络设备侧介绍了本公开实施例的切换方法。下面将介绍候选第二网络设备在本公开实施例的切换方法中的流程。
请参照图4，本公开实施例提供的切换方法，在应用于候选第二网络设备时，包括：
步骤41，候选第二网络设备接收第一网络设备发送的针对一终端的切换请求消息。
这里，第一网络设备在发起针对某个终端的切换时，向至少一个候选第二网络设备发送切换请求消息。
步骤42，候选第二网络设备向所述第一网络设备发送切换请求确认消息，所述切换请求确认消息携带有本候选第二网络设备的多连接能力信息。
这里，所述多连接能力信息可以是用于指示候选第二网络设备是否支持多连接的指示信息，此时，该指示信息可以采用1比特长度的字段来表征。作为另一种实现方式，所述多连接能力信息还可以包括能够与所述候选第二网络设备进行多连接的小区的信息，此时，若所述多连接能力信息指示的能够与所述候选第二网络设备进行多连接的小区为空，则表示候选第二网络设备不支持多连接能力，若非空，则表示支持多连接能力，且同时指示了能够与所述候选第二网络设备进行多连接的小区列表。
这里，候选第二网络设备在接收到上述切换请求消息后，若可以接纳该终端，则向第一网络设备发送切换请求确认消息，并在该消息中携带自身的多连接能力信息。
通过以上步骤，本公开实施例实现了在切换过程中，候选第二网络设备向第一网络设备返回自身的多连接能力信息，使得第一网络设备可以据此选择能够提供多连接服务的候选第二网络设备作为第二网络设备，可以满足高速率服务需求的终端的切换要求，改善了终端的网络体验。
在本公开实施例中，上述步骤41中，第一网络设备发送的所述切换请求消息中可以携带小区集合，所述小区集合包括所述终端测量得到的小区中的全部小区或部分小区。在发送上述步骤42中的切换请求确认消息之前，候选第二网络设备还可以向第一小区对应的网络设备，发送用于添加所述第一小区的辅小区添加请求消息，所述第一小区为所述小区集合中的小区；若候选第二网络设备接收所述第一小区对应的网络设备发送的用于同意辅小区添加的辅小区添加确认消息后，则将所述第一小区作为能够与本候选第二网络设备进行多连接的小区。通过以上添加过程，候选第二网络设备可以确认是否能够与所述小区集合中的小区进行多连接，从而可以针对终端测量得到的小区进行多连接能力的确认，使得提供多连接的辅小区可以为终端测量得到的小区，从而可以提高多连接服务的成功率。
这里，所述切换请求确认消息携带的多连接能力信息为：能够与所述候选第二网络设备进行多连接的小区的小区个数或小区ID，或者为一位图bitmap，所述位图中的比特位一一对应于所述切换请求消息中携带的小区，且比特位的不同取值代表对应小区是否能够与候选第二网络设备进行多连接。
具体地，候选第二网络设备可以在切换请求确认消息中携带能够与所述候选第二网络设备进行多连接的小区的小区个数或小区ID，或者，用位图(bitmap)的方式指示候选第二网络设备与切换请求消息中的小区集合中的各个小区是否可以进行多连接，例如，某个小区对应的比特位为取值1时表示可以，0时表示不可以。当然，也可以某个小区对应的比特位为取值0时表示可以，1时表示不可以。
类似地，候选第二网络设备也可以通过网络设备之间的接口(如X2接 口或Xn接口等)，获取相邻网络设备的双连接能力信息。例如，候选第二网络设备在建立与相邻网络设备之间的网络设备间接口或者在更新网络设备间接口配置时，获取相邻网络设备的多连接能力信息和/或将本候选第二网络设备的多连接能力信息发送给相邻网络设备。具体的，候选第二网络设备可以通过向相邻网络设备发送多连接能力请求消息，并接收相邻网络设备返回的多连接能力反馈消息，该反馈消息中携带有相邻网络设备的多连接能力信息，从而获得相邻网络设备的双连接能力信息。作为另一种实现，候选第二网络设备可以通过多连接能力交互消息，将自身的多连接能力信息发送给相邻网络设备，以及，接收相邻网络设备发送的双连接能力交互消息，获得相邻网络设备的多连接能力信息。
综上，本公开实施例的上述切换方法，第一网络设备在切换过程中获取了候选第二网络设备的多连接能力信息，从而使得第一网络设备可以据此选择能够提供多连接服务的候选第二网络设备作为第二网络设备，可以满足高速率服务需求的终端的切换要求，改善了终端的网络体验。
根据本公开实施例的一个方面，提供了一种信息交互方法，该方法应用于第一网络设备，包括以下步骤：第一网络设备在与其它网络设备之间的网络设备间接口建立或者在更新网络设备间接口配置时，获取其它网络设备的多连接能力信息和/或将本第一网络设备的多连接能力信息发送给其它网络设备。
通过以上步骤，网络设备之间可以通过网络设备之间的接口(如X2接口或Xn接口等)，获取各自的双连接能力信息，以用于后续的切换流程。
基于以上方法，本公开实施例还提供了实施上述方法的设备。
