Description

一种云无线接入网***、数据处理方法及装置Cloud wireless access network system, data processing method and device 技术领域Technical field

本申请涉及通信领域，尤其涉及一种云无线接入网***、数据处理方法及装置。The present application relates to the field of communications, and in particular, to a cloud radio access network system, a data processing method, and an apparatus.

背景技术Background technique

通常，基于通用公共无线接口(英文全称：common public radio interface，英文简称：CPRI)协议可以将基站的内部划分为无线设备控制(英文全称：radio equipment control，英文简称：REC)单元和无线设备(英文全称：radio equipment，英文简称：RE)单元。REC和RE之间采用光纤或者电缆连接。REC设置有多个光口或者电口，一个光口或者电口可以级联多个RE。Generally, based on the common public radio interface (English: wireless common interface: CPRI) protocol, the internal division of the base station can be divided into wireless device control (English full name: radio equipment control, English abbreviation: REC) unit and wireless device ( Full name in English: radio equipment, English abbreviation: RE) unit. Fiber optic or cable connections are used between REC and RE. The REC is provided with multiple optical ports or electrical ports, and one optical port or electrical port can cascade multiple REs.

在单模基站时代，一个REC只支持一种网络制式，例如全球移动通信***(英文全称：Global System for Mobile communication，英文简称：GSM)或通用移动通信***(英文全称：Universal Mobile Telecommunications System，英文简称：UMTS)，此时，一个REC可以管理多个RE，一个RE只从属于一个REC。当RE支持一种网络制式时，REC与RE建立一对一的会话关系。随着基站功能的演进，在多模基站时代，一个RE可以支持多种网络制式，多个REC可以共享一个RE，且RE可以与多个REC中每个REC建立一对一的会话关系，即同时建立了不同网络制式的会话关系。In the era of single-mode base stations, a REC only supports one network standard, such as the Global System for Mobile Communications (English: Global System for Mobile communication, English abbreviation: GSM) or the universal mobile communication system (English full name: Universal Mobile Telecommunications System, English) Abbreviation: UMTS). In this case, one REC can manage multiple REs, and one RE belongs to only one REC. When the RE supports a network standard, the REC establishes a one-to-one conversation relationship with the RE. With the evolution of the function of the base station, in the era of multi-mode base stations, one RE can support multiple network standards, multiple RECs can share one RE, and the RE can establish a one-to-one conversation relationship with each REC of multiple RECs, that is, At the same time, the conversation relationship of different network standards is established.

随着虚拟化(Virtualization)技术的发展，可以基于云无线接入网(英文全称：Cloud Radio Access Network，英文简称：C-RAN)***集中部署虚拟无线设备控制(vREC)节点。但是，在建立vREC节点与RE间的一对一的会话关系时，由于vREC节点是虚拟化的，可以是任意个数，而RE是实体设备，为每个vREC节点提供RE的功能，RE的能力资源有限，RE可能无法同时适配较多的vREC节点，支持较多的vREC节点建立一对一的会话关系。 With the development of virtualization technology, virtual wireless device control (vREC) nodes can be centrally deployed based on the cloud radio access network (English name: Cloud Radio Access Network, English abbreviation: C-RAN). However, when establishing a one-to-one session relationship between the vREC node and the RE, since the vREC node is virtualized, it can be any number, and the RE is an entity device, and the RE function is provided for each vREC node, and the RE The capability resources are limited. The RE may not be able to adapt more vREC nodes at the same time, and support more vREC nodes to establish one-to-one session relationships.

示例的，如图3所示，RE AGENT节点部署的vRE00节点与RE部署的vRE00节点相同的，vRE000节点到vRE00n节点均属于RE AGENT节点部署的vRE00节点，vRE000节点到vRE00n节点均访问RE0，RE0的vRE00节点为vRE000节点到vRE00n节点提供资源。For example, as shown in FIG. 3, the vRE00 node deployed by the RE AGENT node is the same as the vRE00 node deployed by the RE, and the vRE000 node to the vRE00n node belong to the vRE00 node deployed by the RE AGENT node, and the vRE000 node to the vRE00n node access RE0, RE0. The vRE00 node provides resources for the vRE000 node to the vRE00n node.

需要说明的是，图3中的RE还可以部署vRE10节点、vRE20节点等。相应的，RE AGENT节点部署与RE部署的vRE10节点相同的vRE10节点，同时，vRE100节点到vRE10n节点均属于RE AGENT节点部署的vRE10节点，同理，以此类推。It should be noted that the RE in FIG. 3 can also deploy a vRE10 node, a vRE20 node, and the like. Correspondingly, the RE AGENT node deploys the same vRE10 node as the vRE10 node deployed by the RE. At the same time, the vRE100 node to the vRE10n node belong to the vRE10 node deployed by the RE AGENT node, and so on.

RE AGENT节点，还用于将vBTS节点与NFVI节点间的RE接口转换为CPRI接口。The RE AGENT node is also used to convert the RE interface between the vBTS node and the NFVI node into a CPRI interface.

RE AGENT节点，还用于将RE与所述NFVI节点间的CPRI接口转换为RE接口。The RE AGENT node is further configured to convert the CPRI interface between the RE and the NFVI node into an RE interface.

RE AGENT节点，还用于在vBTS所用的vRE和RE之间做多对一映射，针对对vREC节点实现RE的功能，针对RE实现vREC节点的功能，实现上下行转换。The RE AGENT node is also used to perform a multi-to-one mapping between the vRE and the RE used by the vBTS, and implements the function of the RE for the vREC node, and implements the function of the vREC node for the RE to implement uplink and downlink conversion.

具体的，参见CPRI协议实现REC的功能和RE的功能，至少包括以下功能之一：Specifically, refer to the CPRI protocol to implement the functions of the REC and the functions of the RE, including at least one of the following functions:

通信功能，CPRI协议支持REC和RE间通过传输控制协议/因特网互联协议(英文全称：Transmission Control Protocol/Internet Protocol，英文简称：TCP/IP)或者高级数据链路控制(英文全称：High-Level Data Link Control，英文简称：HDLC)方式通信。Communication function, CPRI protocol supports REC and RE through Transmission Control Protocol/Internet Protocol (English full name: Transmission Control Protocol/Internet Protocol, English abbreviation: TCP/IP) or advanced data link control (English full name: High-Level Data Link Control, English abbreviation: HDLC) communication.

设备管理功能，REC和RE间与业务无关的设备管理功能，包括复位、电子标签、RE面板点灯、CPRI口使能、CPRI速率设置、温度查询、功耗查询和驻波测试等。Device management functions, device-independent device management functions between REC and RE, including reset, electronic tag, RE panel lighting, CPRI port enable, CPRI rate setting, temperature query, power query, and standing wave test.

升级管理功能，REC对RE进行版本控制，包括版本查询，版本加载，版本激活，补丁下载和补丁激活等。 Upgrade management function, REC version control of RE, including version query, version loading, version activation, patch download and patch activation.

载波管理功能，REC对RE上的载波进行增加、删除和修改。Carrier management function, REC adds, deletes and modifies the carrier on the RE.

时延管理功能，REC对RE上的载波时延、CPRI转发时延进行查询，将时延补偿配置给RE。The delay management function, the REC queries the carrier delay and the CPRI forwarding delay on the RE, and configures the delay compensation to the RE.

外设管理功能，REC还可以管理挂接在RE上的其它外部设备，比如电调天线、上行低噪声放大器、干结点和风扇等设备。Peripheral management functions, REC can also manage other external devices attached to the RE, such as ESC antennas, uplink low noise amplifiers, dry junctions and fans.

故障管理功能，RE自己监控自身故障，并向REC同步故障信息。Fault management function, the RE itself monitors its own fault and synchronizes the fault information with the REC.

RE AGENT节点，还用于实现管理接口功能，可以对RE AGENT节点的功能和资源进行配置。The RE AGENT node is also used to implement the management interface function and can configure the functions and resources of the RE AGENT node.

例如，配置vRE所用资源。例如按需分配RE载波资源，每个REC可以有属于自己的RE载波资源；或者各REC竞争RE载波资源，当某个REC故障的情况下，其它候选REC可以使用竞争的RE载波资源。For example, configure the resources used by the vRE. For example, the RE carrier resources are allocated on demand, and each REC may have its own RE carrier resources; or each REC contends for the RE carrier resources. When a certain REC fails, other candidate RECs may use the contending RE carrier resources.

vBTS节点，用于实现BTS的功能，每个vBTS节点包括一个vREC节点和第二vRE节点。第二vRE节点的功能由RE提供。BTS可以认为是一个基站。第二vRE节点为图3中示意的所述vBTS节点中的vRE000节点到vRE00n节点。The vBTS node is used to implement the function of the BTS, and each vBTS node includes one vREC node and a second vRE node. The function of the second vRE node is provided by the RE. The BTS can be considered as a base station. The second vRE node is a vRE000 node to a vRE00n node in the vBTS node illustrated in FIG.

需要说明的是，vBTS节点是虚拟化的BTS，需要BTS的功能时，NFVI分配计算资源、存储资源和传输资源建立vBTS，不需要BTS的功能时，NFVI可以释放为建立vBTS而分配的计算资源、存储资源和传输资源，取消vBTS，因此，vBTS节点是比较灵活的。从而vBTS节点所使用的vRE节点的位置也是可以变化的，但是，一旦确定vRE节点的位置，vBTS节点便记录vRE节点的位置，以便于vBTS节点使用vRE节点，因此，vBTS节点包括的第二vRE节点相当于第一vRE的一个索引，而RE AGENT节点包括的第一vRE节点提供了RE的功能。It should be noted that the vBTS node is a virtualized BTS. When the BTS function is required, the NFVI allocates computing resources, storage resources, and transmission resources to establish a vBTS. When the BTS function is not required, the NFVI can release the computing resources allocated for establishing the vBTS. , storage resources and transmission resources, cancel vBTS, therefore, vBTS nodes are more flexible. Thus, the location of the vRE node used by the vBTS node can also be changed, but once the location of the vRE node is determined, the vBTS node records the location of the vRE node so that the vBTS node uses the vRE node, and therefore, the second vRE included in the vBTS node The node is equivalent to an index of the first vRE, and the first vRE node included in the RE AGENT node provides the function of the RE.

其中，vBTS节点通过RE接口与NFVI节点进行通信。通用CPRI定义了基站的REC与基站的RE之间的接口关系。是由工业合作组织，即通用公共无线接口联盟，制定REC与RE间的主要接口 规范。NFVI节点通过CPRI与RE进行通信。The vBTS node communicates with the NFVI node through the RE interface. The general CPRI defines the interface relationship between the REC of the base station and the RE of the base station. Is the main interface between REC and RE by the Industrial Cooperation Organization, the General Public Radio Interface Alliance. specification. The NFVI node communicates with the RE via CPRI.

C-RAN和RE为实体设备，NFVI节点和vBTS节点为部署在C-RAN上的虚拟节点。The C-RAN and the RE are physical devices, and the NFVI node and the vBTS node are virtual nodes deployed on the C-RAN.

这样一来，通过在C-RAN***中的NFVI节点中部署RE AGENT节点，RE AGENT节点可以部署虚拟无线设备(vRE)节点，从而在不修改RE的情况下，对同一个RE虚拟出多个vRE节点，该多个vRE节点对同一个RE进行独立访问，vRE节点与vREC节点建立一对一的会话关系，能够同时适配较多的vREC节点。In this way, by deploying the RE AGENT node in the NFVI node in the C-RAN system, the RE AGENT node can deploy a virtual wireless device (vRE) node, thereby virtualizing multiple copies of the same RE without modifying the RE. The vRE node, the multiple vRE nodes independently access the same RE, and the vRE node establishes a one-to-one session relationship with the vREC node, and can simultaneously adapt more vREC nodes.

Access, the vRE node establishes a one-to-one session relationship with the vREC node, and can simultaneously adapt more vREC nodes.

实施例五 Embodiment 5

本发明实施例提供一种基于C-RAN***的数据处理方法，如图5所示，包括：An embodiment of the present invention provides a data processing method based on a C-RAN system, as shown in FIG. 5, including:

步骤101、虚拟无线设备控制节点向无线设备代理节点发送访问请求。Step 101: The virtual wireless device control node sends an access request to the wireless device proxy node.

所述访问请求包括所述vREC节点的标识和访问的RE的标识。The access request includes an identifier of the vREC node and an identifier of the accessed RE.

需要说明的是，在步骤101之前，网管***需要先创建vBTS节点，并配置vBTS节点可以使用的RE资源，例如RE的位置，可以使用的载波，带宽等。网管***通知NFVI节点创建RE，告知RE各vBTS节点可以使用的RE及载波资源，vBTS节点包括vREC节点。It should be noted that, before step 101, the network management system needs to first create a vBTS node, and configure RE resources that can be used by the vBTS node, such as the location of the RE, the available carrier, bandwidth, and the like. The network management system notifies the NFVI node to create an RE, and informs the REs of the RE and carrier resources that each vBTS node can use, and the vBTS node includes the vREC node.

步骤102、无线设备代理节点接收访问请求。Step 102: The wireless device proxy node receives the access request.

步骤103、无线设备代理节点记录vREC节点的标识和访问的访问的RE的标识，并生成vRE节点。Step 103: The wireless device proxy node records the identifier of the vREC node and the identifier of the accessed access RE, and generates a vRE node.

vRE节点为所述访问的RE的虚拟节点。The vRE node is the virtual node of the accessed RE.

步骤104、无线设备代理节点将所述RE接口转换成通用公共无线接口CPRI接口。Step 104: The wireless device proxy node converts the RE interface into a universal public wireless interface CPRI interface.

无线设备代理综合各虚拟基站收发信台对无线设备的访问，例如对载波编号进行统一转换，转换成统一的CPRI接口方式，将访问消息发给RE。The wireless device agent integrates the access of each virtual base station transceiver station to the wireless device, for example, uniformly converts the carrier number, converts it into a unified CPRI interface mode, and sends the access message to the RE.

步骤105、无线设备代理节点向无线设备发送访问请求。Step 105: The wireless device proxy node sends an access request to the wireless device.

其中，RE AGENT节点对具有相同标识的RE部署vRE节点，vREC节点与vRE节点建立会话关系，对于RE屏蔽多个vREC实例，使得RE认为只有一个vREC实例。The RE AGENT node deploys a vRE node to the RE with the same identifier, and the vREC node establishes a session relationship with the vRE node, and masks multiple vREC instances for the RE, so that the RE considers that there is only one vREC instance.

步骤106、无线设备接收无线设备代理节点发送的访问请求。Step 106: The wireless device receives an access request sent by the wireless device proxy node.

步骤107、无线设备向无线设备代理节点发送响应消息。Step 107: The wireless device sends a response message to the wireless device proxy node.

步骤108、无线设备代理节点接收无线设备发送的响应消息。Step 108: The wireless device proxy node receives a response message sent by the wireless device.

步骤109、无线设备代理节点将所述CPRI转换成所述RE接口。Step 109: The wireless device proxy node converts the CPRI into the RE interface.

对无线设备节点发送的针对请求消息的响应消息。无线设备代理节点收到响应消息后，通常无线设备代理节点根据请求消息的发 送端发送响应消息。发送端可以是虚拟基站收发信台节点或无线设备代理节点。A response message to the request message sent by the wireless device node. After the wireless device proxy node receives the response message, usually the wireless device proxy node sends a response message according to the request message. The sender sends a response message. The transmitting end may be a virtual base transceiver station node or a wireless device proxy node.

无线设备代理节点根据响应消息结果，和资源分配情况，为各虚拟基站收发信台节点生成相应的响应消息。The wireless device proxy node generates a corresponding response message for each virtual base transceiver station node according to the result of the response message and the resource allocation situation.

步骤110、无线设备代理节点向对应的vBTS节点发送响应消息。Step 110: The wireless device proxy node sends a response message to the corresponding vBTS node.

所述响应消息包括所述vREC节点与所述vRE节点间的会话关系的会话标识。The response message includes a session identifier of a session relationship between the vREC node and the vRE node.

这样一来，基于C-RAN***，通过RE AGENT节点建立vRE节点，在不修改RE的情况下，对同一个RE虚拟出多个vRE节点，该多个vRE节点对同一个RE进行独立访问，vRE节点与vREC节点建立一对一的会话关系，能够同时适配较多的vREC节点。In this way, based on the C-RAN system, the vRE node is established through the RE AGENT node, and multiple vRE nodes are virtualized for the same RE without modifying the RE, and the multiple vRE nodes independently access the same RE. The vRE node establishes a one-to-one session relationship with the vREC node, and can simultaneously adapt more vREC nodes.

实施例六Embodiment 6

本发明实施例提供一种基于C-RAN***的数据处理方法，如图6所示，包括：An embodiment of the present invention provides a data processing method based on a C-RAN system, as shown in FIG. 6, including:

步骤201、无线设备向无线设备代理节点发送主动上报消息。Step 201: The wireless device sends an active report message to the wireless device proxy node.

其中，主动上报消息可以为：RE的故障信息以及RE自身的其他行为信息。例如，RE自己会管理自己的故障，这个和REC无关。当RE发现自己故障时，它可以向REC主动报告，这样REC就能即时处理，挽救损失。The active report message may be: the fault information of the RE and other behavior information of the RE itself. For example, RE itself manages its own faults, which has nothing to do with REC. When the RE finds itself faulty, it can report to the REC proactively, so that the REC can handle it immediately and save the loss.

步骤202、无线设备代理节点接收无线设备发送的主动上报消息。Step 202: The wireless device proxy node receives the active report message sent by the wireless device.

步骤203、无线设备代理处理主动上报消息。Step 203: The wireless device proxy processes the active report message.

若主动上报消息与业务相关，将主动上报消息转发给相关的虚拟基站收发信台节点，同时无线设备代理存储业务相关，与业务相关的主动上报消息主要是RE资源的可用状态，比如天线通道的可用状态。若主动上报消息与业务无关，无线设备代理自己处理主动上报消息。If the active report message is related to the service, the active report message is forwarded to the relevant virtual base station transceiver station node, and the wireless device proxy storage service is related. The service-related active report message is mainly the available state of the RE resource, such as the antenna channel. Available status. If the active reporting message is unrelated to the service, the wireless device proxy processes the active reporting message itself.

例如，无线设备代理判断主动上报消息，如果主动上报消息是 与资源分配无关的消息，无线设备代理将主动上报消息发送给所有虚拟基站收发信台节点。如果主动上报消息是与资源分配相关的消息，无线设备代理将主动上报消息发给相关的虚拟基站收发信台。For example, the wireless device agent determines the active reporting message, if the active reporting message is For messages unrelated to resource allocation, the wireless device agent sends an active report message to all virtual base transceiver stations. If the active reporting message is a message related to resource allocation, the wireless device proxy sends an active reporting message to the associated virtual base transceiver station.

需要说明的是，由于虚拟基站收发信台节点和基站收发信台不同，虚拟基站收发信台专注于载波业务，其它的，比如无线设备的升级，虚拟基站收发信台不关心，可以由无线设备代理来完成，无线设备代理还可以直接访问无线设备。无线设备代理接收到升级响应消息，无线设备代理继续加载剩下的安装包。无线设备代理接收到故障响应消息，无线设备代理记录故障信息，以便于网关可以直接查询。It should be noted that, since the virtual base transceiver station node and the base transceiver station are different, the virtual base transceiver station focuses on the carrier service, and other, such as the upgrade of the wireless device, the virtual base transceiver station does not care, and can be used by the wireless device. The agent can complete the wireless device agent and directly access the wireless device. The wireless device agent receives the upgrade response message and the wireless device agent continues to load the remaining installation packages. The wireless device agent receives the fault response message, and the wireless device agent records the fault information so that the gateway can directly query.

所述发送单元303，还用于通过所述RE接口向所述vREC节点发送响应消息，所述响应消息包括所述vREC节点与所述vRE节点间的会话关系的会话标识。The sending unit 303 is further configured to send, by using the RE interface, a response message to the vREC node, where the response message includes a session identifier of a session relationship between the vREC node and the vRE node.

这样一来，通过无线设备代理实现无线设备与虚拟基站收发信台的通信，从而在不修改RE的情况下，对同一个RE虚拟出多个vRE 节点，该多个vRE节点对同一个RE进行独立访问，vRE节点与vREC节点建立一对一的会话关系，能够同时适配较多的vREC节点。In this way, the communication between the wireless device and the virtual base station transceiver station is realized by the wireless device proxy, thereby virtualizing multiple vREs for the same RE without modifying the RE.
