Description

一种确定无线承载方式的方法及装置 技术领域
本公开涉及但不限于，尤指一种确定无线承载方式的方法及装置。
背景技术
现在无线局域网(WLAN)和移动通信技术已经成为了两大最为成功的无线技术，而且一直优势互补。一方面，WLAN中的Wi-Fi技术最大的优势在于，Wi-Fi是在未授权的频谱上运行的，任何人都可以部署Wi-Fi网络，而且能够支持人们能想到的几乎所有智能手持设备或物联网设备。Wi-Fi最适合的是大容量、高密度且低移动性的室内应用。另一方面，移动通信技术在过去几十年里横扫全球，打造出了庞大的无线广域网络，例如全球移动通信系统(GSM)，宽带码分多址(WCDMA)系统，长期演进技术(LTE)系统，第五代移动通信技术(5G)网络。移动通信技术具备无处不在的室外覆盖、无缝的移动等优点，更完美支持语音和流媒体等实时应用。WLAN和移动通信技术的结合将为整个行业带来巨大的希望。
目前，3GPP推出了LTE和WLAN融合(LWA，LTE-WLAN Aggregation)技术，借助LWA技术，可分离移动网络数据有效载荷，即一些流量通过WLAN传输，而剩余的流量则通过移动网络本身来传送，以大大提升移动网络服务的性能。图1为相关技术中LWA的架构图，如图1所示，LWA技术的承载包含分离承载，如图1中split LWA Bearer(分离LWA承载)，以及交换承载，如图1中的Switched LWA Bearer(交换LWA承载)。分离承载表示数据同时在LTE网络和WLAN网络上收发数据，交换承载表示同一时刻只在LTE网络和WLAN网络中的一个网络中收发数据。关于图1的详细说明可以参见相关协议，这里不再赘述。
与此同时，3GPP推出了双连接技术，使得终端在同一个时刻可以连接到两个基站(包括主基站和辅基站)进行数据收发，以提高传输速率，其中，主基站与终端有控制信令交互和数据传输，辅基站与终端之间只有数据传输。图2为相关技术中双连接技术的架构图，如图2所示，双连接技术的承载包含三种承载，分离承载，如图2中的Split Bearer，指在主基站(如图2中的MeNB)和辅基站(如图2中的SeNB)上能同时收发数据；主基站承载，如图2中的MCG Bearer，指仅在主基站上收发数据；辅基站承载，如图2中的SCG Bearer。指仅在辅基站上收发数据。关于图2的详细说明可以参见相关协议，这里不再赘述。
发明内容
为了解决上述技术问题，本公开提供一种确定无线承载方式的方法及装置，能够降低终端数据收发的处理复杂度。
为了达到本公开目的，本公开提供了一种确定无线承载方式的方法，包括：
终端接收承载配置信息；
如果承载配置信息中承载标识对应的承载在终端已经建立，并且为MWA承载，当承载配置信息中指示的承载类型为双连接承载时，终端按照承载配置信息建立或重配置双连接承载；
其中，承载标识用于唯一标识一个承载；承载类型用于指示需要建立或更改的承载。
本申请还提供了一种确定无线承载方式的装置，包括：接收模块、处理模块；其中，
接收模块，设置为接收承载配置信息；
处理模块，设置为在承载配置信息中承载标识对应的承载在终端已经建立，并且为MWA承载，当承载配置信息中指示的承载类型为双连接承载时，按照承载配置信息建立或重配置双连接承载；
其中，承载标识用于唯一标识一个承载；承载类型用于指示需要建立或更改的承载。
本申请还提供了一种存储介质，设置为存储程序代码，所述程序代码用于执行如上任一项所述的方法。
与相关技术相比，本申请技术方案至少包括：终端接收承载配置信息；如果承载配置信息中承载标识对应的承载在终端已经建立，并且为MWA承载，当承载配置信息中指示的承载类型为双连接承载时，终端按照承载配置信息建立或重配置双连接承载。通过本公开提供的技术方案，对于配置了MWA技术的终端执行切换的场景和终端变换收发数据的模式，避免了终端同时配置MWA的无线承载和双连接的无线承载两种无线承载的情形，降低了终端数据收发的处理复杂度，也提供了更灵活的数据收发模式，提高了终端数据收发的效率。
本公开的其它特征和优点将在随后的说明书中阐述，并且，部分地从说明书中变得显而易见，或者通过实施本公开而了解。本公开的目的和其他优点可通过在说明书、权利要求书以及附图中所特别指出的结构来实现和获得。
附图说明
此处所说明的附图用来提供对本公开的进一步理解，构成本申请的一部分，本公开的示意性实施例及其说明用于解释本公开，并不构成对本公开的不当限定。在附图中：
图1为相关技术中LWA的架构图；
图2为相关技术中双连接技术的架构图；
图3为本公开实施例中确定无线承载方式的方法的流程图；
图4为本公开实施例中确定无线承载方式的装置的组成结构示意图。
具体实施方式
为使本公开的目的、技术方案和优点更加清楚明白，下文中将结合附图对本公开的实 施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
在5G系统中，为了提高用户体验，要求在终端切换时数据收发不中断，称为0ms切换。为了满足这个需求，相关技术中，在终端切换时，配置终端使用双连接技术，同时连接到源基站和目标基站，在切换完成后，再通过基站的指示让终端回到单连接状态。
如果终端在切换前被配置使用移动网络与WLAN融合技术，本申请中简称为移动和WLAN融合(MWA，Mobile WLAN Aggregation)技术，那么，按照相关技术的处理，在终端切换时，终端需要根据来自网络侧如基站的配置信息配置终端使用双连接技术，也就是说，此时在终端会同时配置MWA的无线承载和双连接的无线承载两种无线承载，这样，无疑大大增加了终端的数据收发的处理复杂度。其中，MWA技术是上述LWA的一个概括性称呼，表示与WLAN的融合不仅仅局限于LTE网络，还会应用于如5G网络等移动网络。
此外，5G网络中为了给终端更灵活的数据收发模式，可以允许终端根据当前移动网络的信号质量、覆盖范围、周边部署的WLAN接入点的覆盖范围等条件来选择收发数据的模式，比如，为了节省移动网络资源，将双连接模式变换为MWA模式；或者，当WLAN接入点接入的终端过多，数据收发速率明显降低而需要变换为双连接模式等。也就是说，在这些情况下，终端也会面临无线承载建立或重配置的问题，如果终端已被配置使用移动网络与WLAN融合技术，在无线承载建立或重配置过程中，同样存在在终端同时配置MWA和双连接的情况，从而增加了终端的数据收发的处理复杂度。
图3为本公开实施例中确定无线承载方式的方法的流程图，如图3所示，至少包括：
步骤300：终端接收承载配置信息。
可选地，终端可以在切换时，也可以在根据当前移动网络的信号质量、覆盖范围、周边部署的WLAN接入点的覆盖范围等条件选择收发数据的模式时，收到来自网络侧如基站的承载配置信息。这里，网络侧如基站可以将承载配置信息携带来无线资源连接配置信令中下发给终端。
承载配置信息至少包括：用于唯一标识一个承载的承载标识；用于指示需要建立或更改的承载的承载类型。
可选地，承载配置信息还可以包括：分组数据汇聚协议(PDCP，Packet Data Convergence Protocol)配置信息，和/或无线链路控制(RLC，Radio Link Control)协议配置信息，和/或逻辑信道配置信息。
可选地，承载配置信息还可以包括：表示是释放，还是需要建立或重配置第一承载的第一承载信息。
本公开实施例中，承载是无线通信中进行数据传输的逻辑实体，当网络与UE之间有消息要传输时，需要先建立无线承载，相当于在终端和基站间的一个逻辑通道。
步骤301：如果承载配置信息中承载标识对应的承载在终端已经建立，并且为MWA 承载，当承载配置信息中指示的承载类型为双连接承载时，终端按照承载配置信息建立或重配置双连接承载。
本步骤中，终端按照承载配置信息建立或重配置双连接承载包括：
终端根据PDCP配置信息建立或重配置终端本地的PDCP实体，和/或，
终端根据RLC配置信息建立或重配置终端本地的RLC实体，和/或，
终端根据逻辑信道配置信息建立或重配置终端本地的逻辑信道。
本公开实施例还包括：
步骤302：终端关闭MWA应用协议实体中对所述MWA承载的数据处理功能。

通过本公开实施例提供的确定无线承载方式的方法，对于配置了MWA技术的终端执行切换的场景和终端变换收发数据的模式，避免了终端同时配置MWA的无线承载和双连接的无线承载两种无线承载的情形，降低了终端数据收发的处理复杂度，也提供了更灵活的数据收发模式，提高了终端数据收发的效率。
