Description

接收移动网络组播数据的传输方法、 装置及*** 技术领域  Transmission method, device and system for receiving mobile network multicast data
本发明实施例涉及通信技术领域，并且更具体地，涉及 WLAN ( Wireless Local Area Networks, 无线局域网络）终端接收移动网络组播数据的传输方 法、 装置及***。 背景技术  Embodiments of the present invention relate to the field of communications technologies, and, more particularly, to a WLAN (Wireless Local Area Networks) terminal for receiving a mobile network multicast data transmission method, apparatus, and system. Background technique
随着网络技术的发展， 各种不同类型的无线接入技术不断出现， 例如 WiFi ( Wireless Fidelity, 无线保真） 以及 LTE ( Long Term Evolution, 长期 演进）技术等。  With the development of network technologies, various types of wireless access technologies have emerged, such as WiFi (Wireless Fidelity) and LTE (Long Term Evolution) technologies.
作为一种 WLAN技术， 目前 WiFi技术已经广泛应用于个人、 家庭、 企 业、 机场、 酒店、 娱乐和休闲公共场所、 会议展厅等固定场景区域。 支持 WiFi功能成为许多用户终端的标准配置。 随着 WiFi技术的普及， 电信运营 商开始大规模部署室外 AP ( Access Point, 接入点；)， 以形成单独的 WLAN 网络， 为用户提供性价比较高的上网体验。 但是， WLAN网络回传资源需求 大、 成本高。  As a WLAN technology, WiFi technology has been widely used in fixed scene areas such as individuals, homes, businesses, airports, hotels, entertainment and leisure public places, conference halls and the like. Support for WiFi functionality is standard on many user terminals. With the popularity of WiFi technology, telecom operators have begun to deploy outdoor APs (Access Points, access points;) on a large scale to form a separate WLAN network, providing users with a cost-effective online experience. However, the WLAN network has a large demand for returning resources and high cost.
另一方面， LTE技术已经成为移动通信网络演进的标准。 LTE网络除提 供高带宽低时延的点到点单播数据宽带连接服务外， 同时还能够提供支持更 高速率和更好服务质量的点到多点 eMBMS(Enhanced Multimedia Broadcast Multicast Service, 增强型多媒体广播多播业务)。 通过 eMBMS业务可以推 送标清 /高清 TV ( television, 电视）视频业务、 手机报、 天气预报、 体育赛 事、 政府紧急广播消息等丰富的多媒体信息， 满足用户， 企业以及政府等各 种客户群综合信息广播业务的需求。 但是， 目前由于缺乏 LTE终端， 并且 LTE终端价格昂贵， 使得 LTE网络和业务发展受到很大影响。  On the other hand, LTE technology has become the standard for the evolution of mobile communication networks. In addition to providing high-bandwidth and low-latency point-to-point unicast data broadband connection services, LTE networks also provide point-to-multipoint eMBMS (Enhanced Multimedia Broadcast Multicast Service) that supports higher speeds and better quality of service. Broadcast multicast service). Through the eMBMS service, you can push rich multimedia information such as SD/TV (TV) video services, mobile newspapers, weather forecasts, sports events, government emergency broadcast messages, etc., to meet the comprehensive information broadcasting of various customer groups such as users, enterprises and governments. Business needs. However, due to the lack of LTE terminals and the high price of LTE terminals, the development of LTE networks and services is greatly affected.
现有技术中， WiFi终端通过 WLAN认证接入后， 对于集中转发模式， 所有数据流的传输都是通过瘦 AP (瘦 AP是指鉴权认证和设备无线通道管 理由上层设备 AC管理）到 AC ( Access Controller, 无线接入控制器）之间 的 CAPWAP ( Control and Provisioning of Wireless Access Points, 无线接入点 控制协议）隧道，并穿越整个 LTE网络。如果 WiFi终端要去接收 LTE eMBMS 组播数据， 不仅要舍近求远去 BRAS上接收组播数据， 而且一份组播数据会 在 LTE网络传输多份， 这些都会造成网络传输资源的浪费， 特别是 LTE空 口资源的浪费。 还有， 通过 CAPWAP隧道将导致组播数据流传输效率降低。 发明内容 In the prior art, after the WiFi terminal is accessed through the WLAN authentication, in the centralized forwarding mode, all data streams are transmitted through the thin AP (the thin AP refers to the authentication authentication and the device wireless channel management is managed by the upper device AC) to the AC. CAPWAP (Control and Provisioning of Wireless Access Points) tunnel between (Access Controllers, Radio Access Controllers) and traversing the entire LTE network. If the WiFi terminal is going to receive LTE eMBMS multicast data, it is not only necessary to go far to receive the multicast data on the BRAS, but also a multicast data. Multiple transmissions in the LTE network will cause waste of network transmission resources, especially the waste of LTE air interface resources. Also, the CAPWAP tunnel will result in reduced efficiency of multicast data stream transmission. Summary of the invention

图 1是可应用于本发明实施例的 LTE-WiFi网络架构的示意图。  1 is a schematic diagram of an LTE-WiFi network architecture applicable to an embodiment of the present invention.
应理解， 在本发明实施例中， 虽然图 1中描述了两个 WLAN终端 WiFi 终端 101和 WiFi终端 102,两个 WLAN接入设备瘦 AP 103和瘦 AP 104 (瘦 AP是指鉴权认证和设备无线通道管理由上层设备 AC管理）， 两个客户端设 备 CPE 105 ( Customer Premise Equipment, 客户端设备 )和 CPE 106, —个 基站 107等， 但仅仅是为了描述方便。 图 1中各个网络设备的数目可以是一 个或多个， 本发明实施例对此并不限定。  It should be understood that, in the embodiment of the present invention, although two WLAN terminal WiFi terminals 101 and WiFi terminals 102 are described in FIG. 1, two WLAN access devices, a thin AP 103 and a thin AP 104 (thin AP refers to authentication authentication and The device wireless channel management is managed by the upper layer device AC, two client devices CPE 105 (Customer Premise Equipment, client device) and CPE 106, one base station 107, etc., but for convenience of description. The number of the network devices in FIG. 1 may be one or more, which is not limited by the embodiment of the present invention.
在图 1所示的 LTE-WiFi 网络架构中， BRAS 117 ( Broadband Remote Access Server, 宽带远程接入月良务器)与 AAA ( Authentication Authorization Accounting,认证授权计费）服务器 118连接， MME 111( Mobility Management Entity, 移动性管理实体）用于实现控制面功能， HSS 112 ( Home Subscriber Server, 归属用户服务器）用于管理 IMS ( IP Multimedia Subsystem, IP多媒 体子***） 的用户签约数据， S/P GW 113 ( Serving/Packet Data Network Gateway,服务网关 /分组数据网络网关）和 MBMS GW( Multimedia Broadcast Multicast Service Gateway, 多媒体广播多播业务网关） 114用于提供协议转 换、 路由选择、 数据交换等网络兼容功能， BMSC 116 ( Broadcast Multicast Service Controller, 组播广播控制器）用于管理 MBS会话信息， 控制 MBS 业务内容的传送等。  In the LTE-WiFi network architecture shown in FIG. 1, the BRAS 117 (Broadband Remote Access Server) is connected to the AAA (Authentication Authorization Accounting) server 118, and the MME 111 (Mobility) Management Entity (Mobility Management Entity) is used to implement control plane functions. HSS 112 (Home Subscriber Server) is used to manage user subscription data of IMS (IP Multimedia Subsystem, IP Multimedia Subsystem). S/P GW 113 (Serving/Packet Data Network Gateway, Service Gateway/Packet Data Network Gateway) and MBMS GW (Multimedia Broadcast Multicast Service Gateway) 114 are used to provide network compatibility functions such as protocol conversion, routing, and data exchange. The BMSC 116 (Broadcast Multicast Service Controller) is used to manage MBS session information, control the transmission of MBS service content, and the like.
现有技术中， WiFi终端 101/WiFi终端 102通过 WLAN认证接入后， 对 于集中转发模式，所有数据流的传输都是通过瘦 AP 103/瘦 AP 104到 AC 115 ( Access Controller , 无线接入控制器） 之间的 CAPWAP ( Control and Provisioning of Wireless Access Points , 无线接入点控制十办议 ) 1¾道 108/CAPWAP 隧道 109, 并穿越整个 LTE网络。 例如， WiFi终端 101发出 组播请求，通过 CAPWAP隧道 108上报给 AC 115 ,再由 AC 115上报给 BRAS 117, 加入到对应组播组中， 组播数据通过 CAPWAP隧道 108传输给 WiFi 终端 101。  In the prior art, after the WiFi terminal 101/WiFi terminal 102 is accessed through WLAN authentication, for the centralized forwarding mode, all data streams are transmitted through the thin AP 103/thin AP 104 to AC 115 (Access Controller, wireless access control). CAPWAP (Control and Provisioning of Wireless Access Points) 13⁄4way 108/CAPWAP tunnel 109, and traverse the entire LTE network. For example, the WiFi terminal 101 sends a multicast request to the AC 115 through the CAPWAP tunnel 108, and then reports the AC 115 to the BRAS 117 to join the corresponding multicast group. The multicast data is transmitted to the WiFi terminal 101 through the CAPWAP tunnel 108.
因此在整个网络中， 如果 WiFi 终端要去接收 LTE eMBMS(Enhanced Multimedia Broadcast Multicast Service , 增强型多媒体广播多播业务)组播数 据， 不仅要舍近求远去 BRAS上接收组播数据， 而且一份组播数据会在 LTE 网络传输多份，这些都会造成网络传输资源的浪费，特别是 LTE空口资源的 浪费。 还有， 通过 CAPWAP隧道将导致组播数据流传输效率降低。 So in the entire network, if the WiFi terminal is going to receive LTE eMBMS (Enhanced Multimedia Broadcast Multicast Service, enhanced multimedia broadcast multicast service) multicast data, not only to go to the BRAS to receive multicast data, but also a multicast data will be transmitted in the LTE network, which will cause waste of network transmission resources. Especially the waste of LTE air interface resources. Also, the CAPWAP tunnel will result in reduced efficiency of multicast data stream transmission.
为了解决上述问题， 本发明实施例提供一种 WLAN终端接收移动网络 组播数据的传输方法和设备， 能够有效地提高移动网络组播数据的接收效 率， 并避免移动通信网络空口资源的浪费。  In order to solve the above problem, an embodiment of the present invention provides a method and a device for receiving a multicast data of a mobile network by using a WLAN terminal, which can effectively improve the reception efficiency of the multicast data of the mobile network, and avoid waste of the air interface resources of the mobile communication network.

以 LTE-WiFi为例， 接入设备可以是 WiFi瘦 AP与 LTE CPE集成的形 态， 或者基站集成瘦 AP的形态， 还可以是 WiFi瘦 AP等。  Taking LTE-WiFi as an example, the access device may be a form in which a WiFi thin AP is integrated with an LTE CPE, or a base station is integrated with a thin AP, or may be a WiFi thin AP.
201 , WLAN接入设备识别无线局域网 WLAN终端发送的消息是否是第 一组播组请求消息， 第一组播组请求消息携带 WLAN终端地址和组播组地 址。  201. The WLAN access device identifies whether the message sent by the WLAN terminal is a first multicast group request message, and the first multicast group request message carries a WLAN terminal address and a multicast group address.
可选地， WLAN接入设备可以配置参数，该参数用于指示 WLAN接入 设备是否启动组播组请求消息识别功能。 例如， 在 LTE-WiFi网络架构下， WLAN接入设备在接收到 WLAN终端发送的消息时， 首先判断是否有配置 参数， 如果 WLAN接入设备配置了参数， 才识别 WLAN终端发送的消息是 否是第一组播组请求消息。 该参数可以由管理员进行配置， 包括本地配置或 远端配置。  Optionally, the WLAN access device may configure a parameter, where the parameter is used to indicate whether the WLAN access device starts the multicast group request message identification function. For example, in the LTE-WiFi network architecture, when receiving the message sent by the WLAN terminal, the WLAN access device first determines whether there is a configuration parameter, and if the WLAN access device configures the parameter, it identifies whether the message sent by the WLAN terminal is the first. A multicast group request message. This parameter can be configured by the administrator, including local or remote configuration.
可选地， 第一组播组请求消息可以是 IGMP report ( Internet Group Management Protocol report , 互联网组管理协议 4艮告 ) , 包括加入组播组和离 开组播组两种子类型消息，或者 GMRP ( GARP( Generic Attribute Registration Protocol, 通用属' 1"生注册十办议 ) Multicast Registration Protocol, GARP组播注 册协议） 消息， 也可以是其他类型的消息。 比如： 对于有些不支持 IGMP 协议的 WiFi终端， 这些终端本身无法自行发起加入到组播组的 IGMP加入 请求， 但会发送目的 IP地址为组播组地址的数据 文， 通过判断 WiFi终端 上报的数据报文的目的 IP地址是否为组播组地址确定 WiFi终端希望加入组 播组； 然后代替这些 WiFi终端发送相应的 IGMP加入请求。 这样使不支持 IGMP协议的 WiFi终端也可以加入组播组。  Optionally, the first multicast group request message may be an IGMP report (Internet Group Management Protocol report), including two subtype messages of joining a multicast group and leaving a multicast group, or GMRP (GARP) (Generic Attribute Registration Protocol, Generic Attribute Registration Protocol, GARP Multicast Registration Protocol) Messages, or other types of messages. For example: For some WiFi terminals that do not support IGMP, these The terminal itself cannot initiate the IGMP join request to join the multicast group, but it will send the data packet whose destination IP address is the multicast group address, and determine whether the destination IP address of the data packet reported by the WiFi terminal is the multicast group address. The WiFi terminal wants to join the multicast group; then, instead of these WiFi terminals, the corresponding IGMP join request is sent. This allows the WiFi terminal that does not support the IGMP protocol to join the multicast group.
WLAN终端地址可以是 WLAN终端的 IP ( Internet Protocol , 因特网协 议）地址、 MAC ( Media Access Control, 媒体接入控制）地址或其它类型的 地址。 组播组地址可以是发送组播数据的服务器的 IP地址， MAC地址或其 它类型的地址。 本发明对此不作限制。 例如， WLAN终端需要加入某一组播 组，发送第一组播组请求消息， 具体地， 第一组播组请求消息是 IGMP report 加入， 携带 WLAN终端地址 188.0.1.123和组播组地址 232.0.1.99。 The WLAN terminal address can be the IP of the WLAN terminal (Internet Protocol, Internet Protocol) Address, MAC (Media Access Control) address or other type of address. The multicast group address can be the IP address, MAC address or other type of address of the server that sends the multicast data. The invention is not limited thereto. For example, the WLAN terminal needs to join a certain multicast group and send a first multicast group request message. Specifically, the first multicast group request message is an IGMP report join, and carries the WLAN terminal address 188.0.1.123 and the multicast group address 232.0. 1.99.
202, 如果 WLAN终端发送的消息是第一组播组请求消息， 则 WLAN 接入设备根据第一组播组请求消息中携带的组播组地址对第一组播转发表 进行更新；  202. If the message sent by the WLAN terminal is the first multicast group request message, the WLAN access device updates the first multicast forwarding table according to the multicast group address carried in the first multicast group request message.
可选地， 在一种实现方式下， 可建立第一组播组请求消息中携带的组播 组地址和 WLAN终端地址的映射关系， 利用映射关系对第一组播转发表进 行更新。 具体地， 如果第一组播组请求消息表示加入组播组， 则在第一组播 转发表中注册相应的 WLAN终端地址和组播组地址的映射关系。 或者， 如 果第一组播组请求消息表示离开组播组， 则在第一组播转发表中删除相应的 WLAN终端地址和组播组地址的映射关系。  Optionally, in an implementation manner, a mapping relationship between a multicast group address and a WLAN terminal address carried in the first multicast group request message may be established, and the first multicast forwarding table is updated by using a mapping relationship. Specifically, if the first multicast group request message indicates that the multicast group is added, the mapping relationship between the corresponding WLAN terminal address and the multicast group address is registered in the first multicast forwarding table. Or, if the first multicast group request message indicates that the multicast group is left, the mapping relationship between the corresponding WLAN terminal address and the multicast group address is deleted in the first multicast forwarding table.
在另一种实现方式下， 考虑 WLAN接入设备的广播属性， 第一组播转 发表可以省略 WLAN终端地址的字段。 如果第一组播组请求消息表示加入 组播组， 并且该第一组播组请求消息中携带的组播组地址不属于第一组播转 发表， 则在第一组播转发表中注册第一组播组请求消息中携带的组播组地 址。 或者， 如果第一组播组请求消息表示离开组播组， 则向所有 WLAN终 端发送第一查询报文， 以便所有 WLAN终端根据该第一查询报文上报相应 组播组请求消息， 当所有终端上 的相应组播组请求消息均表示离开组播 组， 或者没有 WLAN终端上报相应的组播组请求消息表示加入组播组时， 在第一组播转发表中删除第一组播组请求消息中携带的组播组地址。  In another implementation manner, considering the broadcast attribute of the WLAN access device, the first multicast forwarding may omit the field of the WLAN terminal address. If the first multicast group request message indicates that the multicast group is added to the multicast group, and the multicast group address carried in the first multicast group request message does not belong to the first multicast forwarding table, the first multicast forwarding table is registered. The multicast group address carried in a multicast group request message. Or, if the first multicast group request message indicates to leave the multicast group, send the first query message to all the WLAN terminals, so that all the WLAN terminals report the corresponding multicast group request message according to the first query message, when all the terminals The corresponding multicast group request message on the device indicates that the first multicast group request message is deleted in the first multicast forwarding table when the DM terminal reports that the corresponding multicast group request message is sent to the multicast group. Multicast group address carried in.
203 , WLAN接入设备根据第一组播转发表向 WLAN终端转发移动网络 组播数据；  203. The WLAN access device forwards the mobile network multicast data to the WLAN terminal according to the first multicast forwarding table.
具体的， 所述 WLAN接入设备接收移动网络组播数据； 如果所述组播 数据的组播组地址属于所述第一组播转发表， 则所述 WLAN接入设备将所 述组播数据转发给所述 WLAN终端。  Specifically, the WLAN access device receives the mobile network multicast data; if the multicast group address of the multicast data belongs to the first multicast forwarding table, the WLAN access device uses the multicast data. Forwarded to the WLAN terminal.
另外， 可选地， 在本发明实施例的 WLAN接入设备识别无线局域网 WLAN终端发送的消息是否是第一组播组请求消息之前， WLAN接入设备 可以先向终端发送查询报文， 以便 WLAN终端根据该查询报文上报相应的 组播组请求消息。例如，周期性地向终端发送通用查询 文和 /或特定组查询 报文， 如果 WLAN终端需要接收相应的组播数据， 则 WLAN终端就会进行 响应， 向接入点上艮相应的组播组请求消息。 In addition, optionally, before the WLAN access device of the embodiment of the present invention identifies whether the message sent by the WLAN terminal of the wireless local area network is the first multicast group request message, the WLAN access device may first send the query message to the terminal for the WLAN. The terminal reports the corresponding message according to the query message. Multicast group request message. For example, the general query message and/or the specific group query message are periodically sent to the terminal. If the WLAN terminal needs to receive the corresponding multicast data, the WLAN terminal responds by sending the corresponding multicast group to the access point. Request message.
本发明实施例通过 WLAN接入设备识别无线局域网 WLAN终端发送的 第一组播组请求消息， 并利用第一组播组请求消息中携带的组播组地址更新 第一组播转发表。 这样， 使得 WLAN接入设备能够直接向 WLAN终端转发 移动通信网络组播数据， 不仅使普通 WLAN终端也可以接收移动通信网络 丰富的组播数据业务， 而且可以有效地提高移动通信网络组播数据的接收效 率，并避免移动通信网络空口资源的浪费， WLAN终端直接接收移动网络组 播数据， 提升了 WLAN用户终端的业务体验及移动网络利用率。  In the embodiment of the present invention, the first multicast group request message sent by the WLAN terminal of the wireless local area network is identified by the WLAN access device, and the first multicast forwarding table is updated by using the multicast group address carried in the first multicast group request message. In this way, the WLAN access device can directly forward the mobile communication network multicast data to the WLAN terminal, so that the ordinary WLAN terminal can also receive the rich multicast data service of the mobile communication network, and can effectively improve the multicast data of the mobile communication network. The receiving efficiency and the waste of the air interface resources of the mobile communication network are avoided, and the WLAN terminal directly receives the mobile network multicast data, thereby improving the service experience of the WLAN user terminal and the utilization rate of the mobile network.
本发明实施例还提供另一种 WLAN终端接收移动网络组播数据的传输 方法即在上述任一实施例步骤 202的 WLAN接入设备根据第一组播组请求 消息中携带的组播组地址对第一组播转发表进行更新之前， 可以根据组播组 地址过滤条件对第一组播组请求消息进行过滤处理。 例如， 如果第一组播组 请求消息中携带的组播组地址与组播组地址过滤表中任一个移动网络组播 数据的组播组地址均不相同， 则对该第一组播组请求消息进行过滤处理。 又 例如，组播组地址过滤表中的组播组地址不属于移动网络组播数据的组播组 地址， 如果第一组播组请求消息中携带的组播组地址属于组播组地址过滤 表， 则对该第一组播组请求消息进行过滤处理。 这样， 可以提高组播数据的 转发效率。 此外， 组播组地址过滤表可以由管理员进行配置， 包括本地配置 或远端配置， 本发明实施例对此并不限定。  The embodiment of the present invention further provides another method for transmitting the multicast data of the mobile network by the WLAN terminal, that is, the multicast group address carried by the WLAN access device in step 202 of any one of the foregoing embodiments according to the first multicast group request message. Before the first multicast forwarding table is updated, the first multicast group request message may be filtered according to the multicast group address filtering condition. For example, if the multicast group address carried in the first multicast group request message is different from the multicast group address of any mobile network multicast data in the multicast group address filtering table, the first multicast group request is The message is filtered. For example, the multicast group address in the multicast group address filtering table does not belong to the multicast group address of the mobile network multicast data. If the multicast group address carried in the first multicast group request message belongs to the multicast group address filtering table. Then, the first multicast group request message is filtered. In this way, the forwarding efficiency of multicast data can be improved. In addition, the multicast group address filtering table may be configured by an administrator, including a local configuration or a remote configuration, which is not limited by the embodiment of the present invention.
可选地， 本发明实施例可以对组播组地址过滤条件进行更新。 例如， 接 入设备接收 LTE eMBMS组播数据， 并自动学习识别 LTE eMBMS组播数据 的组播组地址是否属于组播组地址过滤表， 以建立和维护对第一组播组请求 消息进行过滤处理的过滤条件。  Optionally, the embodiment of the present invention may update the multicast group address filtering condition. For example, the access device receives the LTE eMBMS multicast data, and automatically learns whether the multicast group address identifying the LTE eMBMS multicast data belongs to the multicast group address filtering table, so as to establish and maintain the filtering process for the first multicast group request message. Filter conditions.
下面结合具体实施例， 更加详细地描述本发明实施例的组播数据的传输 方法的非限制性的例子。 应注意， 这些例子仅仅是为了帮助本领域技术人员 更好地理解本发明实施例， 而非要限制本发明的范围。  A non-limiting example of a method of transmitting multicast data according to an embodiment of the present invention will now be described in more detail with reference to specific embodiments. It should be noted that these examples are only intended to assist those skilled in the art to better understand the embodiments of the present invention and not to limit the scope of the present invention.
图 3是本发明一个实施例的 WLAN终端接收移动网络组播数据的传输 方法的过程的示意性流程图。  FIG. 3 is a schematic flowchart of a process of a WLAN terminal receiving a transmission method of mobile network multicast data according to an embodiment of the present invention.
在图 3中， WLAN终端以 WiFi终端为例， 接入设备可以是 WiFi瘦 AP 与 LTE CPE集成的形态， 还可以是基站集成 WiFi瘦 AP的形态。 应注意， 本发明实施例中， 以 LTE- WiFi为例进行描述， 但本发明实施例并不限于此。 In FIG. 3, the WLAN terminal takes a WiFi terminal as an example, and the access device may be a WiFi thin AP. The form of integration with the LTE CPE may also be a form in which the base station integrates the WiFi thin AP. It should be noted that, in the embodiment of the present invention, LTE-WiFi is taken as an example for description, but the embodiment of the present invention is not limited thereto.
301 , WiFi终端向接入设备发送某一消息。  301. The WiFi terminal sends a message to the access device.
例如， WiFi终端向接入设备发送的消息可能是组播组请求消息，也可能 是其他消息。  For example, the message sent by the WiFi terminal to the access device may be a multicast group request message or other messages.
302, 接入设备识别第一组播组请求消息。  302. The access device identifies the first multicast group request message.
例如， 第一组播组请求消息可以是 IGMP report, 包括加入组播组和离 开组播组两种子类型消息， 或者 GMRP 消息， 也可以是其他类型的消息。 第一组播组请求消息中携带组播组地址和 WiFi终端地址。  For example, the first multicast group request message may be an IGMP report, including two types of sub-type messages: a join multicast group and an outgoing multicast group, or a GMRP message, or other types of messages. The first multicast group request message carries a multicast group address and a WiFi terminal address.
例如， 接入设备对 WiFi终端发送的消息的类型进行识别， 如果消息的 类型不属于第一组播组请求消息， 则将该数据消息作为普通数据报文进行 CAPWAP封装并通过 CAPWAP 隧道进行转发。如果消息的类型属于第一组 播组请求消息， 则还可以对第一组播组请求消息进行过滤处理， 或者直接对 第一组播转发表进行更新。  For example, the access device identifies the type of the message sent by the WiFi terminal. If the type of the message does not belong to the first multicast group request message, the data message is encapsulated as a common data packet by CAPWAP and forwarded through the CAPWAP tunnel. If the type of the message belongs to the first multicast group request message, the first multicast group request message may be filtered, or the first multicast forwarding table may be directly updated.
303 , 接入设备对第一组播组请求消息进行过滤处理。 组播组地址的过 滤处理可以提高组播数据的转发效率。  303. The access device performs filtering processing on the first multicast group request message. The filtering of multicast group addresses can improve the forwarding efficiency of multicast data.
例如， 预先设置组播组地址过滤表。 例如， 组播组地址过滤表可以由管 理员进行配置， 包括本地配置或远端配置。 另外， 可以通过设备自动学习的 方式更新组播组地址过滤表。 例如， 可解析移动网络组播数据 （例如， LTE eMBMS承载的组播数据）携带的组播组地址信息， 利用该组播组地址信息 更新组播组地址过滤表。  For example, the multicast group address filtering table is set in advance. For example, the multicast group address filtering table can be configured by an administrator, including local configuration or remote configuration. In addition, the multicast group address filtering table can be updated by means of automatic learning of the device. For example, the multicast group address information carried by the mobile network multicast data (for example, the multicast data carried by the LTE eMBMS) can be analyzed, and the multicast group address filtering table is updated by using the multicast group address information.
具体地， 组播组地址过滤表中的组播组地址可以是允许的组播组地址。 在此情况下，如果第一组播组请求消息中携带的组播组地址与组播组地址过 滤表中任一个 LTE eMBMS 载的组播数据的组播组地址均不相同， 则可以 将该第一组播组请求消息作为普通数据报文进行 CAPWAP 封装并通过 CAPWAP隧道进行转发， 或者， 可以将该第一组播组请求消息直接丟弃。  Specifically, the multicast group address in the multicast group address filtering table may be an allowed multicast group address. In this case, if the multicast group address carried in the first multicast group request message is different from the multicast group address of any multicast data carried in the LTE eMBMS in the multicast group address filtering table, The first multicast group request message is encapsulated by the CAPWAP as a common data packet and forwarded by the CAPWAP tunnel, or the first multicast group request message may be directly discarded.
或者， 组播组地址过滤表中的组播组地址可以是禁止的组播组地址。 在 此情况下，如果第一组播组请求消息中携带的组播组地址属于组播组地址过 滤表， 则可以将该第一组播组请求消息作为普通数据报文进行 CAPWAP封 装并通过 CAPWAP隧道进行转发， 或者， 可以将该第一组播组请求消息直 接丟弃。 304, 接入设备更新第一组播转发表。 Alternatively, the multicast group address in the multicast group address filtering table may be a prohibited multicast group address. In this case, if the multicast group address carried in the first multicast group request message belongs to the multicast group address filtering table, the first multicast group request message may be encapsulated as a common data packet by CAPWAP and passed through CAPWAP. The tunnel is forwarded, or the first multicast group request message can be directly discarded. 304. The access device updates the first multicast forwarding table.
例如， 建立第一组播组请求消息中携带的组播组地址和 WiFi终端地址 的映射关系， 利用映射关系对第一组播转发表进行更新。 具体地， 如果第一 组播组请求消息表示加入组播组， 例如， IGMP report加入， 或者 GMRP Join 消息， 则在第一组播转发表中注册相应的 WiFi终端地址和组播组地址的映 射关系。或者，如果第一组播组请求消息表示离开组播组，例如， IGMP report 离开， 或者 GMRP Leave消息， 则在第一组播转发表中删除相应的 WiFi终 端地址和组播组地址的映射关系。  For example, the mapping relationship between the multicast group address and the WiFi terminal address carried in the first multicast group request message is established, and the first multicast forwarding table is updated by using the mapping relationship. Specifically, if the first multicast group request message indicates that the multicast group is added, for example, an IGMP report join, or a GMRP Join message, the mapping of the corresponding WiFi terminal address and the multicast group address is registered in the first multicast forwarding table. relationship. Or, if the first multicast group request message indicates that the multicast group is leaving the multicast group, for example, the IGMP report is left, or the GMRP Leave message is deleted, the mapping relationship between the corresponding WiFi terminal address and the multicast group address is deleted in the first multicast forwarding table. .
又例如， 考虑 WiFi接入设备的广播属性， 可仅仅根据第一组播组请求 消息中携带的组播组地址对第一组播转发表进行更新。 此时无需考虑 WiFi 终端地址。  For another example, considering the broadcast attribute of the WiFi access device, the first multicast forwarding table may be updated only according to the multicast group address carried in the first multicast group request message. There is no need to consider the WiFi terminal address at this time.
具体地， 如果第一组播组请求消息表示加入组播组， 例如， IGMP report 加入，或者 GMRP Join消息， 并且该第一组播组请求消息中携带的组播组地 址不属于第一组播转发表， 则在第一组播转发表中注册第一组播组请求消息 中携带的组播组地址。 或者， 如果第一组播组请求消息表示离开组播组， 则 向所有 WiFi终端发送第一查询报文， 以便所有 WiFi终端根据该第一查询报 文上报相应组播组请求消息， 当所有终端上报的相应组播组请求消息均表示 离开组播组， 例如， IGMP report离开， 或者 GMRP Leave消息， 或者没有 WiFi终端上报相应的组播组请求消息表示加入组播组时，在第一组播转发表 中删除第一组播组请求消息中携带的组播组地址。  Specifically, if the first multicast group request message indicates that the multicast group is added, for example, an IGMP report join, or a GMRP Join message, and the multicast group address carried in the first multicast group request message does not belong to the first multicast. The forwarding table stores the multicast group address carried in the first multicast group request message in the first multicast forwarding table. Or, if the first multicast group request message indicates to leave the multicast group, send the first query message to all the WiFi terminals, so that all the WiFi terminals report the corresponding multicast group request message according to the first query message, when all the terminals The corresponding multicast group request message reported to leave the multicast group, for example, the IGMP report leaves, or the GMRP Leave message, or the no-WiFi terminal reports the corresponding multicast group request message to indicate that the multicast group is added to the multicast group. The multicast group address carried in the first multicast group request message is deleted in the forwarding table.
另外， 为了维护好第一组播转发表， 可以在接入设备上部署 IGMP查询 功能， 周期性地向 WiFi终端发送查询艮文， WiFi终端对该查询艮文进行响 应， 上报相应的组播组请求消息， 例如， WiFi终端需要接收相应的组播数据 时， WiFi终端会进行响应， 上报第一组播组请求消息表示加入组播组。 上述 查询报文也可以是非周期性的， 例如根据需要触发查询报文， 本发明实施例 对此不作限制。  In addition, in order to maintain the first multicast forwarding table, the IGMP query function can be deployed on the access device, and the query message is sent to the WiFi terminal periodically, and the WiFi terminal responds to the query message and reports the corresponding multicast group. The request message, for example, when the WiFi terminal needs to receive the corresponding multicast data, the WiFi terminal responds, and reports the first multicast group request message to join the multicast group. The foregoing query message may also be aperiodic, for example, triggering the query message according to the requirement, which is not limited in the embodiment of the present invention.
305 , 接入设备接收 LTE eMBMS组播数据。  305. The access device receives the LTE eMBMS multicast data.
接入设备会解析 LTE eMBMS组播数据的组播组地址， 并且与第一组播 转发表中的组播组地址进行对比， 根据对比的结果执行组播数据的转发处 理。  The access device resolves the multicast group address of the LTE eMBMS multicast data and compares it with the multicast group address in the first multicast forwarding table, and performs multicast data forwarding processing according to the comparison result.
306, 接入设备向 WiFi终端发送组播数据。 例如， 如果接收的 LTE eMBMS组播数据的组播组地址属于第一组播转 发表， 则将组播数据发送给 WiFi终端。 将组播数据发送给 WiFi终端有多 种方式： 一是在 WiFi口按照组播方式发送给所有 WiFi终端； 二是在 WiFi 口按照单播方式发送给 WiFi终端； 也可以是二种方式的结合： 一部分 WiFi 终端按照组播方式发送， 另外一部分终端按照单播方式发送。 具体实现时可 以结合***处理性能， 频谱利用率， 用户业务体验保障等多方面综合考虑， 选择合适的发送方式和发送策略。 306. The access device sends multicast data to the WiFi terminal. For example, if the received multicast group address of the LTE eMBMS multicast data belongs to the first multicast forwarding table, the multicast data is sent to the WiFi terminal. There are several ways to send multicast data to a WiFi terminal: one is to send the WiFi port to all WiFi terminals according to the multicast mode; the other is to send the WiFi port to the WiFi terminal according to the unicast mode; or a combination of the two methods. : Some WiFi terminals are sent in multicast mode, and some other terminals are sent in unicast mode. In the specific implementation, combined with system processing performance, spectrum utilization, user service experience guarantee and other aspects, select appropriate transmission methods and transmission strategies.
另一方面， 如果在步骤 205中得到的 LTE eMBMS组播数据的组播组地 址不在第一组播转发表中， 则接入设备可以丟弃该 LTE eMBMS组播数据。  On the other hand, if the multicast group address of the LTE eMBMS multicast data obtained in step 205 is not in the first multicast forwarding table, the access device may discard the LTE eMBMS multicast data.
本发明实施例通过接入点识别 WiFi终端发送的第一组播组请求消息， 并利用第一组播组请求消息中携带的组播组地址更新第一组播转发表。 这 样， 使得接入设备能够转发移动网络组播数据， 从而组播数据传输不仅仅限 制在 CAPWAP隧道， 能够有效地提高传输效率。  In the embodiment of the present invention, the first multicast group request message sent by the WiFi terminal is identified by the access point, and the first multicast forwarding table is updated by using the multicast group address carried in the first multicast group request message. In this way, the access device can forward the mobile network multicast data, so that the multicast data transmission is not limited to the CAPWAP tunnel, and the transmission efficiency can be effectively improved.
另外， 本发明实施例接入点可以接收 LTE eMBMS组播数据， 如果 LTE eMBMS组播数据的组播组地址属于第一组播转发表， 则将组播数据发送给 WiFi终端。 这样， 使得 WiFi终端也可以接收 LTE eMBMS组播数据， 提升 了 WiFi用户终端的业务体验及 LTE网络利用率。  In addition, the access point of the embodiment of the present invention can receive the LTE eMBMS multicast data. If the multicast group address of the LTE eMBMS multicast data belongs to the first multicast forwarding table, the multicast data is sent to the WiFi terminal. In this way, the WiFi terminal can also receive the LTE eMBMS multicast data, which improves the service experience of the WiFi user terminal and the utilization of the LTE network.
WLAN接入设备和客户端设备为单独的设备时， WLAN接入设备， 例 如 WiFi AP, 执行图 2和图 3的方法中相同或相应的步骤， 为了避免重复， 此处不再赘述。  When the WLAN access device and the client device are separate devices, the WLAN access device, such as a WiFi AP, performs the same or corresponding steps in the methods of FIG. 2 and FIG. 3, and is not described herein again.
图 4是本发明实施例提供的 WLAN终端接收移动网络组播数据的传输 方法的流程图。 图 4的方法可以由客户端设备执行。 客户端设备的一个例子 是 LTE CPE。  FIG. 4 is a flowchart of a method for transmitting a mobile network multicast data by a WLAN terminal according to an embodiment of the present invention. The method of Figure 4 can be performed by a client device. An example of a client device is LTE CPE.
401 ,客户端设备接收无线局域网 WLAN接入设备发送的第二组播组请 求消息， 第二组播组请求消息携带 WLAN接入设备地址和组播组地址。  401. The client device receives a second multicast group request message sent by the WLAN access device, where the second multicast group request message carries the WLAN access device address and the multicast group address.
402,根据第二组播组请求消息中携带的 WLAN接入设备地址和组播组 地址对第二组播转发表进行更新，第二组播转发表用于客户端设备向 WLAN 接入设备转发移动网络组播数据；  The second multicast forwarding table is updated according to the WLAN access device address and the multicast group address carried in the second multicast group request message, and the second multicast forwarding table is used by the client device to forward to the WLAN access device. Mobile network multicast data;
403 , 客户端设备根据所述第二组播转发表将所述移动网络组播数据转 发给所述 WLAN接入设备。  403. The client device forwards the mobile network multicast data to the WLAN access device according to the second multicast forwarding table.
可选地， 步骤 403具体可以实现为， 接收移动网络组播数据， 如果移动 网络组播数据的组播组地址属于所述第二组播转发表， 则将组播数据发送给Optionally, step 403 is specifically implemented to: receive mobile network multicast data, if mobile The multicast group address of the network multicast data belongs to the second multicast forwarding table, and the multicast data is sent to
WLAN接入设备。 WLAN access device.
可选地， 在本发明实施例的客户端设备可以周期性地向 WLAN接入设 备发送查询报文， WLAN接入设备将查询报文转发给 WLAN终端， 以便 WLAN终端根据该查询报文上报相应的组播组请求消息。 或者， WLAN接 入设备根据第一组播转发表的组播组地址信息进行响应，从而客户端设备能 够维护第二组播转发表。  Optionally, the client device in the embodiment of the present invention may periodically send an Query message to the WLAN access device, and the WLAN access device forwards the Query message to the WLAN terminal, so that the WLAN terminal reports the corresponding message according to the query message. Multicast group request message. Alternatively, the WLAN access device responds according to the multicast group address information of the first multicast forwarding table, so that the client device can maintain the second multicast forwarding table.
需要说明的是,客户端设备可将接收的移动网络组播数据转发给 WLAN 接入设备， 以便 WLAN接入设备利用移动网络组播数据的组播组地址信息 更新前面实施例所述的组播组地址过滤条件。 下面将结合具体的例子详细描 述本发明实施例的组播组地址过滤条件更新方法。  It should be noted that the client device may forward the received mobile network multicast data to the WLAN access device, so that the WLAN access device updates the multicast described in the foregoing embodiment by using the multicast group address information of the mobile network multicast data. Group address filter criteria. The multicast group address filtering condition update method in the embodiment of the present invention will be described in detail below with reference to specific examples.
本发明实施例客户端设备接收移动网络组播数据，如果移动网络组播数 据的组播组地址属于第二组播转发表， 则将组播数据发送给 WLAN接入设 备。或者，将移动网络组播数据转发给 WLAN接入设备。这样，使得 WLAN 接入设备能够转发移动网络组播数据给 WLAN 终端， 能够有效地提高 WLAN终端对移动通信网络组播数据的接收效率。  In the embodiment of the present invention, the client device receives the mobile network multicast data, and if the multicast group address of the mobile network multicast data belongs to the second multicast forwarding table, the multicast data is sent to the WLAN access device. Alternatively, the mobile network multicast data is forwarded to the WLAN access device. In this way, the WLAN access device can forward the mobile network multicast data to the WLAN terminal, which can effectively improve the receiving efficiency of the WLAN terminal for the multicast data of the mobile communication network.
下面结合具体实施例， 更加详细地描述本发明实施例的组播数据的传输 方法的非限制性的例子。  A non-limiting example of a method of transmitting multicast data according to an embodiment of the present invention will now be described in more detail with reference to specific embodiments.
图 5是本发明另一实施例的可适用于图 1的网络架构的 WLAN终端接 收移动网络组播数据的传输方法的过程的示意性流程图。  FIG. 5 is a schematic flowchart of a process of a WLAN terminal for receiving a mobile network multicast data transmission method applicable to the network architecture of FIG. 1 according to another embodiment of the present invention.
在图 5中， 接入设备分为 WLAN接入设备和客户端设备两个实体。 其 中， 客户端设备以 LTE CPE为例， WLAN接入设备以 WiFi AP为例。 将适 当省略与图 3的实施例重复的描述。  In Figure 5, the access device is divided into two entities: a WLAN access device and a client device. The LTE CPE is used as an example for the client device and the WiFi AP is used as the WLAN access device. Descriptions overlapping with the embodiment of Fig. 3 will be omitted as appropriate.
501 , WiFi终端向 WiFi AP发送某一消息。  501. The WiFi terminal sends a message to the WiFi AP.
例如， WiFi终端 101向瘦 AP 103发送的消息可能是组播组请求消息， 也可能是其他消息。  For example, the message sent by the WiFi terminal 101 to the thin AP 103 may be a multicast group request message or other messages.
502 , WiFi AP识别第一组播组请求消息。  502. The WiFi AP identifies the first multicast group request message.
例如， 第一组播组请求消息可以是 IGMP report, 包括加入组播组和离 开组播组两种子类型消息， 或者 GMRP 消息， 也可以是其他类型的消息。 第一组播组请求消息中携带组播组地址和 WiFi终端 101地址。  For example, the first multicast group request message may be an IGMP report, including two types of sub-type messages: a join multicast group and an outgoing multicast group, or a GMRP message, or other types of messages. The first multicast group request message carries a multicast group address and a WiFi terminal 101 address.
例如， 瘦 AP 103对 WiFi终端 101发送的消息的类型进行识别， 如果消 息的类型不属于第一组播组请求消息， 则将该数据消息作为普通数据报文进 行 CAPWAP封装并通过 CAPWAP 隧道 108进行转发。 如果消息的类型属 于第一组播组请求消息， 则还可以对第一组播组请求消息进行过滤处理， 或 者直接对第一组播转发表进行更新。 For example, the thin AP 103 identifies the type of the message sent by the WiFi terminal 101, if If the type of the information does not belong to the first multicast group request message, the data message is encapsulated as a normal data packet by CAPWAP and forwarded through the CAPWAP tunnel 108. If the type of the message belongs to the first multicast group request message, the first multicast group request message may be filtered, or the first multicast forwarding table may be directly updated.
503, WiFi AP对第一组播组请求消息进行过滤处理。  503. The WiFi AP performs filtering processing on the first multicast group request message.
例如， 预先设置组播组地址过滤表。 例如， 组播组地址过滤表可以由管 理员进行配置， 包括本地配置或远端配置。 另外， 可以通过自动学习的方式 更新组播组地址过滤表。 例如， 瘦 AP 103可解析移动网络组播数据（例如， LTE eMBMS承载的组播数据）携带的组播组地址信息， 利用该组播组地址 信息更新组播组地址过滤表。  For example, the multicast group address filtering table is set in advance. For example, the multicast group address filtering table can be configured by an administrator, including local configuration or remote configuration. In addition, the multicast group address filtering table can be updated by means of automatic learning. For example, the thin AP 103 can parse the multicast group address information carried by the mobile network multicast data (for example, the multicast data carried by the LTE eMBMS), and update the multicast group address filtering table by using the multicast group address information.
具体地， 组播组地址过滤表中的组播组地址可以是允许的组播组地址。 在此情况下，如果第一组播组请求消息中携带的组播组地址与组播组地址过 滤表中任一个 LTE eMBMS 载的组播数据的组播组地址均不相同， 则可以 将该第一组播组请求消息作为普通数据报文进行 CAPWAP 封装并通过 CAPWAP隧道 108进行转发， 或者， 可以将该第一组播组请求消息直接丟 弃。  Specifically, the multicast group address in the multicast group address filtering table may be an allowed multicast group address. In this case, if the multicast group address carried in the first multicast group request message is different from the multicast group address of any multicast data carried in the LTE eMBMS in the multicast group address filtering table, The first multicast group request message is CAPWAP encapsulated as a normal data packet and forwarded by the CAPWAP tunnel 108. Alternatively, the first multicast group request message may be directly discarded.
或者， 组播组地址过滤表中的组播组地址可以是禁止的组播组地址。 在 此情况下，如果第一组播组请求消息中携带的组播组地址属于组播组地址过 滤表， 则可以将该第一组播组请求消息作为普通数据报文进行 CAPWAP封 装并通过 CAPWAP隧道 108进行转发， 或者， 可以将该第一组播组请求消 息直接丟弃。  Alternatively, the multicast group address in the multicast group address filtering table may be a prohibited multicast group address. In this case, if the multicast group address carried in the first multicast group request message belongs to the multicast group address filtering table, the first multicast group request message may be encapsulated as a common data packet by CAPWAP and passed through CAPWAP. The tunnel 108 forwards the packet, or the first multicast group request message may be directly discarded.
504 , WiFi AP更新第一组播转发表。  504. The WiFi AP updates the first multicast forwarding table.
例如， 建立第一组播组请求消息中携带的组播组地址和 WiFi终端 101 地址的映射关系， 利用映射关系对第一组播转发表进行更新。 具体地， 如果 第一组播组请求消息表示加入组播组，例如， IGMP report加入， 或者 GMRP Join消息， 则在第一组播转发表中注册相应的 WiFi终端地址和组播组地址 的映射关系。 或者， 如果第一组播组请求消息表示离开组播组， 例如， IGMP report离开，或者 GMRP Leave消息，则在第一组播转发表中删除相应的 WiFi 终端 101地址和组播组地址的映射关系。  For example, the mapping relationship between the multicast group address carried in the first multicast group request message and the address of the WiFi terminal 101 is established, and the first multicast forwarding table is updated by using the mapping relationship. Specifically, if the first multicast group request message indicates that the multicast group is added, for example, an IGMP report join, or a GMRP Join message, the mapping of the corresponding WiFi terminal address and the multicast group address is registered in the first multicast forwarding table. relationship. Or, if the first multicast group request message indicates that the multicast group is left, for example, the IGMP report leaves, or the GMRP Leave message, the mapping of the corresponding WiFi terminal 101 address and the multicast group address is deleted in the first multicast forwarding table. relationship.
又例如， 考虑 WiFi接入设备的广播属性， 可仅仅根据第一组播组请求 消息中携带的组播组地址对第一组播转发表进行更新。 此时无需考虑 WiFi 终端地址。 For example, considering the broadcast attribute of the WiFi access device, the first multicast forwarding table may be updated only according to the multicast group address carried in the first multicast group request message. No need to consider WiFi at this time Terminal address.
具体地， 如果第一组播组请求消息表示加入组播组， 例如， IGMP report 加入， 或者 GMRP Join消息， 并且该第一组播组请求消息中携带的组播组地 址不属于第一组播转发表， 则在第一组播转发表中注册第一组播组请求消息 中携带的组播组地址。 或者， 如果第一组播组请求消息表示离开组播组， 则 向所有 WiFi终端发送第一查询报文， 以便所有 WiFi终端根据该第一查询报 文上报相应组播组请求消息， 当所有终端上报的相应组播组请求消息均表示 离开组播组， 例如， IGMP report离开， 或者 GMRP Leave消息， 或者没有 WiFi终端上报相应的组播组请求消息表示加入组播组时，在第一组播转发表 中删除第一组播组请求消息中携带的组播组地址。  Specifically, if the first multicast group request message indicates that the multicast group is added to the multicast group, for example, an IGMP report join, or a GMRP Join message, and the multicast group address carried in the first multicast group request message does not belong to the first multicast group. The forwarding table stores the multicast group address carried in the first multicast group request message in the first multicast forwarding table. Or, if the first multicast group request message indicates to leave the multicast group, send the first query message to all the WiFi terminals, so that all the WiFi terminals report the corresponding multicast group request message according to the first query message, when all the terminals The corresponding multicast group request message reported to leave the multicast group, for example, the IGMP report leaves, or the GMRP Leave message, or the no-WiFi terminal reports the corresponding multicast group request message to indicate that the multicast group is added to the multicast group. The multicast group address carried in the first multicast group request message is deleted in the forwarding table.
瘦 AP 103在更新第一组播转发表成功后， 向 LTE CPE 105发送第二组 播组请求消息， 携带瘦 AP 103地址和组播组地址。 如果 LTE CPE 105对未 注册的组播数据转发策略不是丟弃，而是广播转发，则瘦 AP 103向 LTE CPE 105发送第二组播组请求信息是可选的。  After updating the first multicast forwarding table, the thin AP 103 sends a second multicast group request message to the LTE CPE 105, carrying the thin AP 103 address and the multicast group address. If the LTE CPE 105 does not discard the unregistered multicast data forwarding policy, but broadcasts, the sending of the second multicast group request information by the thin AP 103 to the LTE CPE 105 is optional.
505 , LTE CPE接收 WiFi AP发送的第二组播组请求消息。  505. The LTE CPE receives the second multicast group request message sent by the WiFi AP.
例如， LTE CPE 105接收瘦 AP 103发送的第二组播组地址请求消息可 以是 IGMP report ( Internet Group Management Protocol report, 互联网组管理 协议报告）， 包括加入组播组和离开组播组两种子类型消息， 或者 GMRP ( GARP ( Generic Attribute Registration Protocol , 通用属生注册十办议） Multicast Registration Protocol, GARP组播注册协议） 消息。 第二组播组地 址请求消息携带了瘦 AP 103地址和组播组地址。  For example, the second multicast group address request message sent by the LTE CPE 105 to the thin AP 103 may be an IGMP report (Internet Group Management Protocol report), including two types of joining a multicast group and leaving a multicast group. Message, or GMRP (GARP (Generic Attribute Registration Protocol) Multicast Registration Protocol). The second multicast group address request message carries the thin AP 103 address and the multicast group address.
506, LTE CPE更新第二组播转发表。  506. The LTE CPE updates the second multicast forwarding table.
例如， LTE CPE 105根据第二组播组请求消息携带的瘦 AP 103地址和 组播组地址的映射关系对第二组播转发表进行更新。 具体地， 对于第二组播 转发表的更新方式可以参照图 3实施例中第一组播转发表的更新方式， 因此 不再赘述。  For example, the LTE CPE 105 updates the second multicast forwarding table according to the mapping relationship between the thin AP 103 address and the multicast group address carried in the second multicast group request message. For the update manner of the second multicast forwarding table, refer to the update manner of the first multicast forwarding table in the embodiment of FIG. 3, and therefore, details are not described herein.
为了维护好第二组播转发表， 可以在 LTE CPE上部署 IGMP查询功能， 周期性地向 WiFi AP发送查询报文， WiFi AP将查询报文转发给 WiFi终端， 以便 WiFi终端根据该查询报文上报相应的组播组请求消息。例如， LTE CPE 105周期性地向瘦 AP 103发送通用查询报文和 /或特定组查询报文，瘦 AP 103 支持透明转发查询报文， 如果 WiFi终端 101需要接收相应的组播数据时， WiFi终端 101会进行响应， 向瘦 ΑΡ 103上 相应的组播组请求消息。 To maintain the second multicast forwarding table, the IGMP query function can be deployed on the LTE CPE to periodically send the query message to the WiFi AP. The WiFi AP forwards the query message to the WiFi terminal, so that the WiFi terminal can query the packet according to the query. Report the corresponding multicast group request message. For example, the LTE CPE 105 periodically sends the general query message and/or the specific group query message to the thin AP 103, and the thin AP 103 supports the transparent forwarding query message. If the WiFi terminal 101 needs to receive the corresponding multicast data, The WiFi terminal 101 responds by requesting a message to the corresponding multicast group on the thin port 103.
另外，还可以在 LTE CPE和 WiFi AP上都部署 IGMP查询功能， 即 LTE CPE和 WiFi AP都周期性地发送通用查询报文和 /或特定组查询报文。 在这 文和 /或特定组查询报文可以是透明转发模式，还可以是本地终结模式。本地 终结模式即 WiFi AP接收 LTE CPE周期性发送的通用查询报文和 /或特定组 查询报文， 根据第一组播转发表的组播组地址信息向 LTE CPE发送相应的 响应消息， 而不再向 WiFi终端转发。  In addition, the IGMP query function can be deployed on both the LTE CPE and the WiFi AP. That is, both the LTE CPE and the WiFi AP periodically send general query messages and/or specific group query messages. The message and/or the specific group query message may be a transparent forwarding mode or a local termination mode. The local end mode, that is, the WiFi AP receives the general query message and/or the specific group query message periodically sent by the LTE CPE, and sends a corresponding response message to the LTE CPE according to the multicast group address information of the first multicast forwarding table, instead of Forward to the WiFi terminal.
507 , LTE CPE接收 LTE eMBMS组播数据。  507. The LTE CPE receives the LTE eMBMS multicast data.
例如， LTE CPE 105接收经 eMBMS通道 110传输的 LTE eMBMS组播 数据。  For example, LTE CPE 105 receives LTE eMBMS multicast data transmitted over eMBMS tunnel 110.
508 , LTE CPE对 LTE eMBMS的组播数据进行转发处理。  508. The LTE CPE forwards the multicast data of the LTE eMBMS.
例如， LTE CPE 105会解析 LTE eMBMS组播数据的组播组地址， 并且 与第二组播转发表中的组播组地址进行对比 ,根据对比的结果执行组播数据 的转发处理。  For example, the LTE CPE 105 parses the multicast group address of the LTE eMBMS multicast data, and compares it with the multicast group address in the second multicast forwarding table, and performs multicast data forwarding processing according to the comparison result.
另一方面，如果 LTE CPE 105在步骤 507中得到的 LTE eMBMS组播数 据的组播组地址不在第二组播转发表中， 则 LTE CPE 105可以丟弃该 LTE eMBMS组播数据。  On the other hand, if the multicast group address of the LTE eMBMS multicast data obtained by the LTE CPE 105 in step 507 is not in the second multicast forwarding table, the LTE CPE 105 may discard the LTE eMBMS multicast data.
509 , LTE CPE将组播数据发送给 WiFi AP。  509. The LTE CPE sends the multicast data to the WiFi AP.
例如， LTE CPE 105将组播数据发送给瘦 AP 103。  For example, the LTE CPE 105 transmits multicast data to the thin AP 103.
510, WiFi AP将组播数据发送给 WiFi终端。  510. The WiFi AP sends the multicast data to the WiFi terminal.
例如， 如果瘦 AP 103接收的组播数据的组播组地址属于第一组播转发 表， 则将组播数据转发给 WiFi终端 101。  For example, if the multicast group address of the multicast data received by the thin AP 103 belongs to the first multicast forwarding table, the multicast data is forwarded to the WiFi terminal 101.
另一方面， 如果瘦 AP 103在步骤 509中得到的 LTE eMBMS组播数据 的组播组地址不在第一组播转发表中，则瘦 AP 103可以丟弃该 LTE eMBMS 组播数据。  On the other hand, if the multicast group address of the LTE eMBMS multicast data obtained by the thin AP 103 in step 509 is not in the first multicast forwarding table, the thin AP 103 may discard the LTE eMBMS multicast data.
这样， WiFi AP能够接收除 CAPWAP隧道外传输的 LTE eMBMS组播数 据， 从而提高传输效率， 还能够提升 WiFi用户终端的业务体验及 LTE网络 利用率。  In this way, the WiFi AP can receive LTE eMBMS multicast data transmitted in addition to the CAPWAP tunnel, thereby improving transmission efficiency, and improving the service experience of the WiFi user terminal and the utilization rate of the LTE network.
需说明的是， 本发明实施例中如果 WiFi AP与 LTE CPE集成在一起， 则以上 WiFi AP与 LTE CPE之间的消息交互属于设备的内部流程， 有些流 程可以适当合并，筒化或裁剪掉，但并不影响本发明的实质精神。如果是 eNB 集成瘦 AP形态， 则不需要 CPE, eMBMS组播数据直接到 eNB后， 通过内 部交换传递给瘦 AP, 本领域普通技术人员可以通过本发明实施例提供的流 程图得到这个交互的流程图， 只不过将 LTE CPE换成 eNB基站即可， 这种 形态只是瘦 AP部署位置不同而已。 It should be noted that, in the embodiment of the present invention, if the WiFi AP is integrated with the LTE CPE, the message interaction between the above WiFi AP and the LTE CPE belongs to the internal process of the device, and some flows. The process can be combined, collapsed or cut, but does not affect the spirit of the invention. If the eNB is in the form of an integrated thin AP, the CPE is not required, and the eMBMS multicast data is directly transmitted to the eNB and then transmitted to the thin AP through the internal exchange. The process of the interaction can be obtained by using the flowchart provided by the embodiment of the present invention. In the figure, it is only necessary to replace the LTE CPE with the eNB base station. This form is only a different location for the thin AP deployment.
图 6是本发明另一实施例的可适用于图 1的网络架构的组播组地址过滤 条件更新方法的过程的示意性流程图。  FIG. 6 is a schematic flowchart of a process of a method for updating a multicast group address filtering condition applicable to the network architecture of FIG. 1 according to another embodiment of the present invention.
应理解， 本发明实施例中， 以 LTE-WiFi为例进行描述， 但本发明实施 例并不限于此。  It should be understood that, in the embodiment of the present invention, LTE-WiFi is taken as an example for description, but the embodiment of the present invention is not limited thereto.
601 , LTE CPE接收 LTE eMBMS组播数据。  601. The LTE CPE receives the LTE eMBMS multicast data.
例如， LTE CPE 105接收经 eMBMS通道 110传输的 LTE eMBMS组播 数据。 LTE CPE 105可以解析出 LTE eMBMS组播数据携带的组播组地址信 息。  For example, LTE CPE 105 receives LTE eMBMS multicast data transmitted over eMBMS tunnel 110. The LTE CPE 105 can parse the multicast group address information carried by the LTE eMBMS multicast data.
602 , LTE CPE向 WiFi AP发送组播组地址信息。  602. The LTE CPE sends the multicast group address information to the WiFi AP.
603 , WiFi AP利用 LTE CPE发送的组播组地址信息， 更新 WiFi AP上 存储的组播组地址过滤表。  603. The WiFi AP updates the multicast group address filtering table stored in the WiFi AP by using the multicast group address information sent by the LTE CPE.
例如， LTE CPE 105接收 LTE eMBMS组播数据， 并将解析出的 LTE eMBMS组播数据携带的组播组地址信息发送给瘦 AP 103, 瘦 AP 103 自动 识别 LTE eMBMS组播数据的组播组地址是否属于组播组地址过滤表， 对组 播组地址过滤表进行更新。 或者， LTE CPE 105将接收的 LTE eMBMS组播 数据转发给瘦 AP 103 , 瘦 AP 103解析出的 LTE eMBMS组播数据携带的组 播组地址信息， 并识别 LTE eMBMS组播数据的组播组地址是否属于组播组 地址过滤表， 对组播组地址过滤表进行更新。 这样， 建立和维护了对第一组 播组请求消息进行过滤处理的过滤条件。  For example, the LTE CPE 105 receives the LTE eMBMS multicast data, and sends the parsed multicast group address information carried by the LTE eMBMS multicast data to the thin AP 103, and the thin AP 103 automatically identifies the multicast group address of the LTE eMBMS multicast data. Whether it belongs to the multicast group address filtering table and updates the multicast group address filtering table. Alternatively, the LTE CPE 105 forwards the received LTE eMBMS multicast data to the thin AP 103, and the multicast group address information carried by the LTE eMBMS multicast data parsed by the thin AP 103, and identifies the multicast group address of the LTE eMBMS multicast data. Whether it belongs to the multicast group address filtering table and updates the multicast group address filtering table. In this way, the filtering conditions for filtering the first multicast group request message are established and maintained.
此外， 组播组地址过滤表可以由管理员进行配置， 包括本地配置或远端 配置， 本发明实施例对此不作限制。  In addition, the multicast group address filtering table may be configured by an administrator, including a local configuration or a remote configuration.
这样， 可以维护组播组地址过滤条件， 提高组播数据的转发效率。  In this way, multicast group address filtering conditions can be maintained to improve the forwarding efficiency of multicast data.
