Description

信息发送方法及装置、网络选择方法及装置和基站Information sending method and device, network selection method and device, and base station

技术领域Technical field

本公开涉及通信技术领域，尤其涉及一种信息发送方法及装置、网络选择方法及装置、基站、用户设备和计算机可读存储介质。The present disclosure relates to the field of communication technology, and in particular to an information sending method and device, a network selection method and device, a base station, user equipment, and a computer-readable storage medium.

背景技术Background technique

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***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。Facing 2020 and the future, mobile communication technology and industry will enter the development stage of the fifth generation mobile communication technology (5th Generation, referred to as 5G). 5G will meet people's needs for ultra-high traffic density, ultra-high connection density, and ultra-high mobility, and can provide users with the ultimate service experience of high-definition video, virtual reality, augmented reality, cloud desktop, and online games. 5G will penetrate into the Internet of Things and other fields, and will be deeply integrated with industrial facilities, medical equipment, and transportation, effectively meeting the needs of information services in vertical industries such as industry, medical treatment, and transportation. It can be seen that the types of services, terminal types, and service types that 5G networks can support in the future will be more diverse and richer than those in the 4th Generation (4G) network era, and different services will have a greater impact on 5G network technology. The requirements of indicators are also different, such as mobility requirements, billing requirements, security requirements, delay requirements, and reliability requirements.

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，运营商难以扩展电信网络，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。The traditional cellular network adopts a "one size fits all" network architecture, which is very suitable for a single-service network. However, with this vertical architecture, it is difficult for operators to expand their telecommunications networks, and it is also difficult for operators to adjust according to the aforementioned changing user, business, and industry needs, and to meet the needs of new applications. Therefore, in 5G networks, the traditional "one size fits all" model of cellular networks can no longer meet the different network needs of various industries in the 5G era. Operators need to take certain measures to flexibly adjust and combine network performance indicators such as speed, capacity, and coverage, so as to meet the individual needs of different services.

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。Network slicing is one of the means to solve the above problems. The network resources are sliced. A single physical network can be divided into multiple logical virtual networks. Independent network slices are allocated for typical business scenarios. In the slices, enhanced business requirements are designed. The network architecture realizes proper resource allocation and process optimization. Multiple network slices share network infrastructure, thereby improving the utilization of network resources and providing the best support for different services used by different user groups.

根据第三代合作伙伴计划(Third Generation Partnership Project，简称3GPP)协议，现有的网络切片部署是以跟踪区域(Tracking Area，简称TA)为单位进行部署，即一个TA内支持的网络切片的种类是一致的。According to the Third Generation Partnership Project (3GPP) agreement, the existing network slice deployment is deployed in units of Tracking Area (TA), that is, the types of network slices supported in a TA Is consistent.

图1是本申请一示例性实施例示出的一种信息发送方法的流程图，该实施例从基站侧进行描述，如图1所示，该信息发送方法包括：Fig. 1 is a flowchart of an information sending method shown in an exemplary embodiment of the present application. This embodiment is described from the base station side. As shown in Fig. 1, the information sending method includes:

在步骤S101中，接收核心网为该基站配置的该基站支持的网络切片信息。In step S101, receive network slice information supported by the base station configured by the core network for the base station.

其中，核心网可以为基站配置该基站支持的网络切片。Among them, the core network may configure the base station with network slices supported by the base station.

在步骤S102中，通过***信息向UE发送该基站支持的网络切片信息。In step S102, the network slice information supported by the base station is sent to the UE through system information.

其中，***信息可以包括第一***信息块(SIB1)，即该实施例可以通过SIB1向UE发送基站支持的网络切片信息。例如，可以SIB1中的小区接入相关信息(CellAccessRelatedInfo)信息单元向UE发送基站支持的网络切片信息。The system information may include the first system information block (SIB1), that is, this embodiment may send the network slice information supported by the base station to the UE through the SIB1. For example, the cell access related information (CellAccessRelatedInfo) information unit in SIB1 may send the network slice information supported by the base station to the UE.

在该实施例中，通过SIB1中的小区接入相关信息CellAccessRelatedInfo信息单元向UE发送基站支持的网络切片信息可以包括但不局限于以下两种方式：In this embodiment, sending the network slice information supported by the base station to the UE through the cell access related information CellAccessRelatedInfo information unit in SIB1 may include but is not limited to the following two methods:

方式11)将基站支持的网络切片信息作为一个独立的信息单元添加到CellAccessRelatedInfo中，向UE发送CellAccessRelatedInfo。Manner 11) The network slice information supported by the base station is added to the CellAccessRelatedInfo as an independent information unit, and the CellAccessRelatedInfo is sent to the UE.

在该实施例中，直接将基站支持的网络切片信息作为一个独立的信息单元添加到CellAccessRelatedInfo中。In this embodiment, the network slice information supported by the base station is directly added to CellAccessRelatedInfo as an independent information unit.

其中，CellAccessRelatedInfo信息单元的格式可以为：Among them, the format of the CellAccessRelatedInfo information unit can be:

其中，加粗字体部分表示基站支持的网络切片信息。Among them, the bold font indicates the network slice information supported by the base station.

方式12)将基站支持的网络切片信息添加到公共陆地移动网络标识信息(PLMN-IdentityInfo)中，向UE发送PLMN-IdentityInfo。Manner 12) The network slice information supported by the base station is added to the public land mobile network identification information (PLMN-IdentityInfo), and the PLMN-IdentityInfo is sent to the UE.

在该实施例中，可以将基站支持的网络切片信息添加到位于CellAccessRelatedInfo中的PLMN-IdentityInfo中。In this embodiment, the network slice information supported by the base station may be added to the PLMN-IdentityInfo located in CellAccessRelatedInfo.

由此可见，该实施例可以通过多种方式向UE发送基站支持的网络切片信息。It can be seen that in this embodiment, the network slice information supported by the base station can be sent to the UE in multiple ways.

上述实施例，通过接收核心网为基站配置的基站支持的网络切片信息，并通过***信息向UE发送基站支持的网络切片信息，使得UE可以获知每个基站支持的网络切片，并可以根据基站支持的网络切片的信息和自己支持的网络切片的信息选择接入的网络，从而避免***资源和信令的浪费。In the above embodiment, by receiving the network slicing information supported by the base station configured by the core network for the base station, and sending the network slicing information supported by the base station to the UE through the system information, the UE can learn the network slicing supported by each base station, and can be based on the base station support The network slice information of the network slice and the information of the network slice supported by itself select the network to be accessed, so as to avoid the waste of system resources and signaling.

图2是本申请一示例性实施例示出的一种网络选择方法的流程图，该实施例从UE侧进行描述，如图2所示，该方法包括：Fig. 2 is a flowchart of a network selection method shown in an exemplary embodiment of the present application. This embodiment is described from the UE side. As shown in Fig. 2, the method includes:

在步骤S201中，接收至少一个基站发送的***信息。In step S201, system information sent by at least one base station is received.

其中，***信息包括SIB1。在该实施例中，UE可以接收一个或多个基站发送的SIB1。Among them, the system information includes SIB1. In this embodiment, the UE may receive SIB1 sent by one or more base stations.

在步骤S202中，从***信息获取每个基站支持的网络切片信息。In step S202, the network slice information supported by each base station is obtained from the system information.

在步骤S203中，根据每个基站支持的网络切片信息和UE支持的网络切片信息选择接入网络。In step S203, an access network is selected according to the network slice information supported by each base station and the network slice information supported by the UE.

其中，根据每个基站支持的网络切片信息和UE支持的网络切片信息选择接入网络可以包括以下两种方式：Among them, selecting an access network according to the network slice information supported by each base station and the network slice information supported by the UE may include the following two methods:

方式21)若根据当前基站支持的网络切片信息和UE支持的网络切片信息确定当前基站支持的网络切片和UE支持的网络切片均不同，则不接入当前基站所在的网络。Manner 21) If it is determined that the network slice supported by the current base station and the network slice supported by the UE are different according to the network slice information supported by the current base station and the network slice information supported by the UE, then the network where the current base station is located is not accessed.

方式22)若根据每个基站支持的网络切片信息和UE支持的网络切片信息确定多个基站支持的网络切片与UE支持的网络切片均至少部分相同，则选择网络切片相同数量最多的目标基站，接入目标基站所在的网络。Manner 22) If it is determined according to the network slice information supported by each base station and the network slice information supported by the UE that the network slices supported by the multiple base stations are at least partially the same as the network slices supported by the UE, then the target base station with the same number of network slices is selected, Access the network where the target base station is located.

其中，若网络切片相同数量最多的基站为一个，则直接将网络切片相同数量最多的基站作为目标基站。若网络切片相同数量最多的基站为多个，则可以随机从中选择一个基站作为目标基站，也可以获取这多个基站的资源状态，并根据这多个资源状态选择一个基站作为目标基站。Among them, if there is one base station with the same number of network slices, the base station with the same number of network slices is directly used as the target base station. If there are multiple base stations with the same maximum number of network slices, one base station can be randomly selected as the target base station, or the resource status of the multiple base stations can be obtained, and one base station can be selected as the target base station according to the multiple resource statuses.

例如，UE获取到基站1支持的网络切片为切片1、2、3，基站2支持的网络切片为切片1、2、4，基站3支持的网络切片为切片1、3、5，UE支持的网络切片为切片1、2、3，由于基站1和UE具有相同网络切片的数量最多，因此，选择基站1为目标基站，以接入目标基站所在的网络。For example, the UE obtains that the network slices supported by base station 1 are slices 1, 2, and 3, the network slices supported by base station 2 are slices 1, 2, and 4, and the network slices supported by base station 3 are slices 1, 3, and 5. The network slices are slices 1, 2, and 3. Since base station 1 and the UE have the largest number of the same network slices, base station 1 is selected as the target base station to access the network where the target base station is located.

例如，UE获取到基站1支持的网络切片为切片1、2、3，基站2支持的网络切片为切片1、2、4，基站3支持的网络切片为切片1、3、5，UE支持的网络切片为切片1、2，由于基站1、基站2和UE具有相同网络切片的数量最多，可以随机选择基站1或基站2为目标基站，也可以根据基站1和基站2的资源状态，选择空闲资源较多的基站作为目标基站，以接入目标基站所在的网络。For example, the UE obtains that the network slices supported by base station 1 are slices 1, 2, and 3, the network slices supported by base station 2 are slices 1, 2, and 4, and the network slices supported by base station 3 are slices 1, 3, and 5. The network slices are slices 1 and 2.
