具体实施方式detailed description

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings.

本发明实施例提供的切换方法的执行主体可以为一种支持虚拟化的基站，该支持虚拟化的基站能够虚拟化成为多个具有隔离度的虚拟基站，各个虚拟基站能够同时独立地为多个虚拟运营商服务。其中，多个具有隔离度的虚拟基站包括两方面的含义：一方面指各个虚拟基站的子***之间隔离，例如，各个虚拟控制管理***之间隔离；另一方面指各个虚拟基站的分配资源隔离，例如，各个虚拟基站的频带资源隔离。The executor of the handover method provided by the embodiment of the present invention may be a base station supporting virtualization, and the base station supporting virtualization may be virtualized into multiple virtual base stations with isolation, and each virtual base station can be multiple independently at the same time. Virtual carrier service. The multiple virtual base stations with isolation include two aspects: on the one hand, the isolation between the subsystems of the virtual base stations, for example, the isolation between the virtual control management systems; on the other hand, the allocation resources of the virtual base stations. Isolation, for example, band resource isolation of each virtual base station.

进一步地，如图1所示，该支持虚拟化的基站可以包括：基本节点物理资源、控制管理***和控制转发实体。 Further, as shown in FIG. 1, the base station supporting virtualization may include: a basic node physical resource, a control management system, and a control forwarding entity.

其中，所述基本节点物理资源可以包括：频带资源、基带***、射频***、时钟***、电源环境监控***和天馈***等在内的基础硬件资源。所述基本节点物理资源包括但不限于LTE***中基站的所有物理资源。The basic node physical resources may include basic hardware resources such as a frequency band resource, a baseband system, a radio frequency system, a clock system, a power environment monitoring system, and an antenna feeder system. The basic node physical resources include, but are not limited to, all physical resources of a base station in an LTE system.

其中，所述控制管理***可以包括：宿主控制管理***(HCMS，Host Control&Management System)和虚拟控制管理***(VCMS，Virtual Control&Management System)。具体的，一个HCMS可以同时维护多个VCMS，反映在基站实体上，即可以理解为，一个实体基站可以同时维护多个虚拟基站。The control management system may include: a Host Control & Management System (HCMS) and a Virtual Control & Management System (VCMS). Specifically, an HCMS can maintain multiple VCMSs at the same time, which is reflected in the base station entity, that is, an entity base station can simultaneously maintain multiple virtual base stations.

其中，所述宿主控制管理***至少具有测量监视、数据存储、核心管理等功能。The host control management system has at least functions of measurement monitoring, data storage, core management, and the like.

测量监视功能是对涉及基站状态的各个指标的周期性测量，例如，监视基站的工作状态，如有超负载等异常发生，所述测量监视模块设置为向所述核心管理模块发送异常请求，维护基站的正常运作。The measurement monitoring function is a periodic measurement of various indicators related to the state of the base station, for example, monitoring the working state of the base station, if an abnormality occurs such as an overload, the measurement monitoring module is configured to send an abnormal request to the core management module, and maintain The normal operation of the base station.

数据存储功能是对基站及虚拟基站数据、用户数据、信令数据等的存储。其中，虚拟基站数据至少包括：虚拟基站的编码(ID，identification)、虚拟基站所占用的频带资源、虚拟基站所服务的用户平均信号与干扰加噪声比(SINR，Signal to Interference plus Noise Ratio)等。The data storage function is storage of base station and virtual base station data, user data, signaling data, and the like. The virtual base station data includes at least: an ID (identification) of the virtual base station, a frequency band resource occupied by the virtual base station, a user average signal and a signal to interference plus noise ratio (SINR) served by the virtual base station, and the like. .

The core management functions include, but are not limited to, the following aspects: configuration function, authentication function, resource allocation, mobility management, band management, and the like.

进一步地，所述虚拟控制管理***是以所述宿主控制管理***中的核心管理模块在虚拟网络中作为一个具有控制管理功能的网元的功能实现。虚拟基站是能够运行基站(eNodeB，Evolved Node B)协议栈实现基站功能的逻辑实体，VCMS通过应用程序编程接口(API，Application Programming Interface)调用HCMS的核心管理模块的管理功能模板实现虚拟基站的具体控制管理功能。Further, the virtual control management system is implemented by a core management module in the host control management system as a function of a network element having a control management function in a virtual network. The virtual base station is a logical entity capable of running a base station (eNodeB, Evolved Node B) protocol stack to implement the function of the base station. The VCMS calls the management function template of the core management module of the HCMS through an application programming interface (API) to implement the virtual base station. Control management functions.

进一步地，每一个实体基站内部都集成一个基于承载的控制转发实体，所述控制转发实体，设置为维护所述实体基站所服务的不同虚拟网络承载列表，所述控制转发实体与虚拟运营商服务器进行直接交互，将属于不同虚拟网络的承载隔离开，从而保证不同虚拟网络之间的隔离度。其中，承载列表信息至少可以包括：虚拟网络ID，虚拟网络优先级，IP源地址、目标地址、协议等。Further, each of the physical base stations integrates a bearer-based control forwarding entity, and the control forwarding entity is configured to maintain different virtual network bearers served by the physical base station. In the list, the control forwarding entity directly interacts with the virtual carrier server to isolate bearers belonging to different virtual networks, thereby ensuring isolation between different virtual networks. The bearer list information may include at least: a virtual network ID, a virtual network priority, an IP source address, a target address, a protocol, and the like.

如图2所示，为多个支持虚拟化的基站与多个虚拟运营商之间的一种拓扑结构，一方面，在该支持虚拟化的基站端，每个基站分布式地自主控制管理从属于不同虚拟网络的虚拟基站；另一方面在虚拟运营商端，虚拟运营商服务器集中控制管理该虚拟运营商的整个虚拟网络。多个基站和多个虚拟运营商存在的情况下，就会有图2中所示的拓扑结构图，这种控制管理方式把分布式和集中式结合起来，在有效管理的同时又不失灵活性。As shown in FIG. 2, it is a topology between multiple base stations supporting virtualization and multiple virtual operators. On the one hand, at the base station side supporting virtualization, each base station distributes autonomously and manages dependent subordinates. On the virtual carrier side, the virtual carrier server centrally controls and manages the entire virtual network of the virtual operator. In the case where multiple base stations and multiple virtual operators exist, there will be a topology diagram shown in Figure 2. This control management method combines distributed and centralized, and effectively manages without losing flexibility. .

如图3所示，为多层虚拟网络***网元之间的信息交互示意图，图中包括三方面的信息交互，基站与虚拟运营商服务器之间有信息交互；基站与核心网之间有信息交互；虚拟运营商服务器与核心网之间有信息交互。As shown in FIG. 3, it is a schematic diagram of information interaction between network elements of a multi-layer virtual network system. The figure includes three aspects of information interaction, and information exchange between the base station and the virtual carrier server; information between the base station and the core network Interaction; there is information interaction between the virtual carrier server and the core network.

需要说明的是，本发明实施例中描述的支持虚拟化的基站和实体基站的含义相同，可以理解为，该实体基站支持虚拟化，该实体基站能够虚拟化成为多个具有隔离度的虚拟基站，各个虚拟基站能够同时独立地为多个虚拟运营商服务。It should be noted that the base station supporting the virtualization described in the embodiment of the present invention has the same meaning as the entity base station. It can be understood that the entity base station supports virtualization, and the entity base station can be virtualized into multiple virtual base stations with isolation. Each virtual base station can simultaneously serve multiple virtual operators independently.
