Description

连接建立方法及装置、基站、用户设备和核心网设备 技术领域
本公开涉及通信技术领域，尤其涉及一种连接建立方法及装置、基站、用户设备和核心网设备。
背景技术
面向2020年及未来，移动通信技术和产业将迈入第五代移动通信技术(5th Generation，简称5G)的发展阶段。5G将满足人们超高流量密度、超高连接数密度、超高移动性的需求，能够为用户提供高清视频、虚拟现实、增强现实、云桌面、在线游戏等极致业务体验。5G将渗透到物联网等领域，与工业设施、医疗仪器、交通工具等深度融合，有效满足工业、医疗、交通等垂直行业的信息化服务需要。由此可见，未来5G网络能够支持的业务种类、终端种类、服务种类与第四代移动通信技术(4th Generation，简称4G)网络时代相比会更加多样、更加丰富，并且不同业务对5G网络技术指标的要求也不尽相同，例如，移动性要求、计费要求、安全性要求、时延要求和可靠性要求等。
传统蜂窝网采用“一刀切”的网络架构，非常适合单一服务型的网络。然而，使用这种垂直架构，运营商难以扩展网络，也很难根据前面所提到的不断变化的用户、业务及行业需求进行调整，并满足新型应用的需求。因此，在5G网络中，传统的蜂窝网络“一刀切”的模式已经不能满足5G时代各行各业对网络的不同需求。运营商需要采取一定的措施对速率、容量和覆盖率等网络性能指标进行灵活调整和组合，从而满足不同业务的个性化需求。
而网络切片是解决上述问题的手段之一，将网络资源进行切片，单一物理网络可以划分成多个逻辑虚拟网络，为典型的业务场景分配独立的网络切片，在切片内针对业务需求设计增强的网络架构，实现恰到好处的资源分配和流程优化，多个网络切片共用网络基础设施，从而提高网络资源利用率，为不同用户群使用的不同业务提供最佳支持。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
根据第三代合作伙伴计划(Third Generation Partnership Project，简称3GPP)协议，终端最多同时支持8个网络切片，并且，不同的基站可以支持不同类型的网络切片。但是，目前无线侧不会对网络切片进行区分，当有业务需要传输给空闲态UE时，空闲态UE在连接建立时不知道业务来自哪个网络切片，需要逐个尝试使用自己支持的每个网络切片与基站进行连接，耗时长。
图1是本申请一示例性实施例示出的一种连接建立方法的流程图，该实施例从基站侧进行描述，如图1所示，该连接建立方法包括：
在步骤S101中，接收核心网发送的待传输业务对应的网络切片信息和目标UE 信息。
其中，待传输业务可以包括但不局限于超可靠低时延(Ultra Reliable Low Latency Communication，简称URLLC)业务和增强移动宽带(enhanced Mobile Broad Band，简称eMBB)业务等。
当核心网有待传输业务需要传输给目标UE即处于空闲态的UE时，可以向基站发送待传输业务对应的网络切片信息和目标UE信息，该网络切片信息可以包括一个或多个网络切片标识。
其中，基站可以通过核心网和基站之间的接口接收核心网发送的第一寻呼信令，并从第一寻呼信令中获取待传输业务对应的网络切片信息和目标UE信息。
当基站为4G基站时，核心网和基站之间的接口可以为S1接口，当基站为5G基站时，核心网和基站之间的接口可以为下一代(Next Generation，简称NG)接口。
在步骤S102中，向目标UE信息对应的目标UE发送网络切片信息，网络切片信息用于目标UE与基站建立连接。
基站在接收到待传输业务对应的网络切片信息之后，可以在第二寻呼信令中添加网络切片信息，并通过空中接口向目标UE信息对应的目标UE发送添加有网络切片信息的第二寻呼信令。
在该实施例中，可以通过多种方式在第二寻呼信令中添加网络切片信息：
方式11)在第二寻呼信令中添加新的信令，并在该新的信令中添加网络切片信息。
方式12)在第二寻呼信令中添加新的信息单元，并在该新的信息单元中添加网络切片信息。
方式13)在第二寻呼信令的已有信令中添加网络切片信息。
例如，已有信令可以为PagingRecord，添加有网络切片信息的第二寻呼信令如下所示，其中，黑色加粗部分为所添加的网络切片信息：
Figure PCTCN2019113886-appb-000001
Figure PCTCN2019113886-appb-000002
在该实施例中，UE接收网络切片信息之后，可以根据网络切片信息与基站建立连接。
需要说明的是，上述第一寻呼信令和第二寻呼信令不是信令的名称，而是用于区分不同的寻呼信令。
上述实施例，通过接收核心网发送的待传输业务对应的网络切片信息，并向目标UE发送网络切片信息，使得目标UE可以根据待传输业务对应的网络切片与基站进行连接，相对于目标UE逐个尝试使用自己支持的每个网络切片与基站进行连接，可以减少连接建立所消耗的时长和资源。
图2是本申请一示例性实施例示出的另一种连接建立方法的流程图，该实施例从UE侧进行描述，如图2所示，该连接建立方法包括：
在步骤S201中，接收基站发送的待传输业务对应的网络切片信息。
在该实施例，UE可以通过空中接口接收基站发送的第二寻呼信令，并从第二寻呼信令中获取网络切片信息。
由于基站可以在第二寻呼信令的新的信令中添加网络切片信息，因此，UE可以从第二寻呼信令的新的信令中获取网络切片信息。
由于基站可以在第二寻呼信令的新的信息单元中添加网络切片信息，因此，UE可以从第二寻呼信令的新的信息单元中获取网络切片信息。
由于基站可以在第二寻呼信令的已有信令中添加网络切片信息，因此，UE可以从第二寻呼信令的已有信令中获取网络切片信息。
在步骤S202中，根据接收的网络切片信息与基站建立连接。
其中，根据网络切片信息与基站建立连接可以包括但不局限于：根据网络切片信息从UE支持的网络切片中选择目标网络切片，并基于目标网络切片与基站建立连接。
在该实施例中，根据网络切片信息从UE支持的网络切片中选择目标网络切片可以包括但不局限于以下情形：
情形11)当网络切片信息包括一个网络切片标识时，从UE支持的网络切片中选择网络切片标识对应的网络切片，并将所选择的网络切片标识对应的网络切片作为目标网络切片。
例如，网络切片信息包括的网络切片标识为3，则UE从自己支持的多个网络切片中选择网络切片3，并将网络切片3作为目标网络切片。
情形12)当网络切片信息包括多个网络切片标识时，从多个网络切片标识中选择优先级最高的网络切片标识，将所选择的网络切片标识对应的网络切片作为目标网络切片，其中，多个网络切片标识对应的多个网络切片位于UE支持的网络切片集合中。
其中，网络切片的优先级预先设置，例如预先设置网络切片2的优先级最高，则可以选择网络切片2作为目标网络切片。
情形13)当网络切片信息包括多个网络切片标识时，将多个网络切片标识对应的多个网络切片作为目标网络切片，其中，多个网络切片标识对应的多个网络切片位于UE支持的网络切片集合中。
例如，网络切片信息包括的网络切片标识为1、2和3，则可以将网络切片1、2和3作为目标网络切片。
情形14)当网络切片信息包括多个网络切片标识时，从多个网络切片标识中随机选择一个网络切片标识，将所选择的网络切片标识对应的网络切片作为目标网络切片，其中，多个网络切片标识对应的多个网络切片位于UE支持的网络切片集合中。
例如，网络切片信息包括网络切片标识为1、2和3，则可以从网络切片1、2和 3中随机选择一个网络切片标识，假设选择的网络切片为网络切片1，则将网络切片1作为目标网络切片。
需要说明的是，上述仅为选择目标网络切片的示例，在实际应用中，可以根据需要采用上述任一方式或其他方式选择目标网络切片。
上述实施例，通过接收基站发送的待传输业务对应的网络切片信息，可以根据待传输业务对应的网络切片与基站进行连接，相对于目标UE逐个尝试使用自己支持的每个网络切片与基站进行连接，可以减少连接建立所消耗的时长和资源。
图3是本申请一示例性实施例示出的又一种连接建立方法的流程图，该实施例从核心网侧进行描述，如图3所示，该连接建立方法包括：
在步骤S301中，确定需要向目标UE传输待传输业务。

当核心网有待传输业务需要传输给目标UE即处于空闲态的UE时，向基站发送待传输业务对应的网络切片信息，该网络切片信息可以包括一个或多个网络切片标识。
其中，核心网可以通过在第一寻呼信令中添加待传输业务对应的网络切片信息，并通过核心网和基站之间的接口向基站发送添加有网络切片信息的第一寻呼信令。
上述实施例，若确定需要向目标UE传输待传输业务，则向基站发送待传输业务对应的网络切片信息，使得基站可以向目标UE发送待传输业务对应的网络切片信息，从而为UE减少连接建立所消耗的时长和资源提供条件。
图4是本申请一示例性实施例示出的一种连接建立方法的信令流程图，该实施例从核心网、基站和UE交互的角度进行描述，如图4所示，该连接建立方法包括：
在步骤S401中，核心网若确定需要向目标UE传输待传输业务，则向基站发送第一寻呼信令，其中，第一寻呼信令中携带待传输业务对应的网络切片信息和目标UE信息。
在步骤S402中，基站从第一寻呼信息中获取待传输业务对应的网络切片信息和目标UE信息，并向目标UE发送第二寻呼信令，其中，第二寻呼信令中携带待传输业务对应的网络切片信息。
在步骤S403中，目标UE接收第二寻呼信令，并从中获取待传输业务对应的网络切片信息。
在步骤S404中，目标UE根据待传输业务对应的网络切片信息与基站建立连接，并开始传输业务数据。
上述实施例，通过核心网、基站和目标UE之间的交互，使得目标UE可以根据待传输业务对应的网络切片与基站进行连接，相对于目标UE逐个尝试使用自己支持的每个网络切片与基站进行连接，可以大大减少连接建立所消耗的时长和资源。
