Description

IPTV系统中的数据处理方法及网元设备 技术领域
本发明涉及数据处理技术，尤其涉及一种IPTV系统中的数据处理方法、接入网元设备及注册网元设备。
背景技术
本申请发明人在实现本申请实施例技术方案的过程中，至少发现相关技术中存在如下技术问题：
随着各种多屏终端在IPTV系统中的应用，多屏互动业务逐渐成为一种受家庭用户欢迎的新型业务，这就要求IPTV系统能为用户提供在网络机顶盒(STB)、PC、手机、PAD等终端上无缝切换的业务服务，但是当不同终端属于不同的网络平台(比如宽带网络与移动网络)，终端间的消息通讯则需要通过多屏网关进行转发，以实现多屏互动业务，让用户可以随时随地通过手机、PC、TV平滑灵活地进行业务切换和业务共享，而多屏网关要实现多屏业务，不能简单的进行消息转发，还需要对IPTV的终端数据进行管理，供其他终端进行查询，并维护终端的在线状态信息，从而，如何对IPTV系统中的终端数据进行处理成为要解决的问题。
如图1所示为IPTV系统的分布式多屏网关的总体架构图，包括多个注册服务器，多个终端及一个接入服务器，接入服务器用于为注册服务器分配ID，控制终端到注册服务器进行注册，对IPTV系统中的终端数据进行处理是利用接入服务器对IPTV系统中的终端数据进行集中式的处理。
目前存在的问题是：由于利用接入服务器对IPTV系统中的终端数据进行集中式的处理，因此，当注册服务器出现增减时，需要过多的人工干预，终端数据的迁移不能自动平滑过渡，进而会影响到整个IPTV系统的稳定 性。然而，对于这个问题，并未存在有效的解决方案。

本发明实施例应用于具体的IPTV多屏业务，主要包括以下内容：
实现上述数据处理技术的两个核心模块：一个是接入网元设备，具体为接入服务器；另一个是注册网元设备，具体为注册服务器，这两个模块 的功能分别为：
接入服务器：负责终端和机顶盒的接入负载均衡和注册服务器的分配。
注册服务器：负责终端用户信息的获取、维护，包括注册、保活。
接入服务器在系统中只有一台，作为单点，采用双机的方式保证其可靠性。主要承担着对注册服务器进行维护、对终端用户接入信息的处理等功能。
注册服务器承载着终端数据的管理，注册服务器有多台，采用分布式的方式对终端数据进行管理。系统中的多台注册服务器由接入服务器进行管理，当注册服务器启动时，会到接入服务器进行注册，上报自身的信息，接入服务器维护系统中注册服务器的相关信息，并给每个注册服务器分配一个ID值，然后将维护的信息推送给所有注册服务器，这样系统中所有注册服务器都知道其他注册服务器的信息，当注册服务器异常挂掉或者新增一台注册服务器时，接入服务器会重新给各个注册服务器分配一个新的ID值，然后及时通知到其他注册服务器，通过这种分布式的控制机制，对于系统中注册服务器的变化情况，其他注册服务器都能够及时感知到，并根据变化情况进行终端数据的自动迁移。
当终端比如机顶盒和终端开机后，会首先发送接入消息到接入服务器进行接入，接入服务器在收到终端的接入消息后，根据终端的Device ID计算hash值，然后选取一个ID值与终端的hash值最接近的注册服务器返回给终端，在返回消息中，接入服务器会把注册服务器的IP地址和hash值返回给终端。终端在收到接入服务器的返回消息后，将注册服务器地址和hash值保存下来，向注册服务器发送注册消息，上报自身的信息，注册服务器根据终端的Device ID在内存中建立索引，保存并维护终端的信息。后续终端会定时向注册服务器发送心跳，心跳消息中会把hash值报给注册服务器。
本发明实施例主要通过多屏网关的接入服务器、注册服务器与终端的配合，实现了当注册服务器出现增减情况时用户数据在注册服务器之间的迁移，同时实现了终端心跳消息发送的迁移。对于注册服务器，当终端通过心跳消息维护自身的在线状态信息时，在终端的心跳消息中带了接入服务器给终端计算的hash值，注册服务器在收到心跳消息后，解析消息中的hash值，然后根据自身维护的系统中所有注册服务器的信息，检查该终端的hash值是否和本注册服务器的ID值是最接近的，如果在终端心跳消息期间，注册服务器发生了变化，由于接入重新给注册服务器分配了新的ID值，则该终端的hash值可能和其他注册服务器的ID值最接近，因此这种情况下终端需要迁移，注册服务器会在心跳消息的返回消息中将新的注册服务器地址返回给终端，同时在自身内存中删除该终端的相关信息，终端在收到该消息后，会重新向新的注册服务器进行注册和心跳保活，其信息由新的注册服务器进行维护
如图6所示为应用本发明实施例的一具体应用场景的完整流程，接入网元设备具体为多屏网关的接入服务器，注册网元设备具体为多屏网关的注册服务器，本应用场景中，以所述注册服务器为两个为例，实际应用中不限于两个，该流程包括所述接入服务器启动，在特定端口上起监听的预处理步骤，还包括以下步骤：
步骤601、所述注册服务器启动，向所述接入服务器的监听端口建立连接，上报自身的注册相关信息；所述注册服务器向所述接入服务器定时发送心跳消息，维护自身的在线状态信息。
这里，针对所述心跳消息而言，因为该消息像心跳一样每隔固定时间发一次，以此来告诉接入服务器，这个注册服务器还活着。也就是说，发送心跳消息是为了确认一个事实——互联的双方在长时间没有通讯的情况下是否都还在线，或者说存在于互联的双方之间的通讯链路是否已经断开。 连接一旦建立，只能被异常或正常的断开，而不会因为没有数据传输而断开。
步骤602、接入服务器在收到多个注册服务器的注册相关信息后，将注册相关信息保存并在接入服务器维护起来，并为每个注册服务器分配一个ID值。
步骤603、接入服务器将自身维护的注册服务器的相关信息推送给所有注册服务器，这样每个注册服务器都知道系统中其他注册服务器的相关信息。
这里，注册服务器减少的情况包括：当注册服务器异常挂掉时，接入服务器会通过连接(如TCP连接)是否存在或者心跳是否超时来判断某台注册服务器是否异常，如果异常，则会为每个注册服务器重新分配一个ID值，并通知到其他存活的注册服务器。
这里，注册服务器增加的情况包括：当新增一台注册服务器时，新增的注册服务器会自动与接入服务器建立连接，并上报自身状态信息，接入服务器在收到上报信息后，在自身维护的注册服务器列表中增加新增注册服务器的信息，同时，会为各个注册服务器重新计算hash值，并将所有的注册服务器相关信息推送给注册服务器。
步骤604、IPTV终端在接入多屏网关系统时，通过接入消息向接入服务器申请进行接入。
步骤605、接入服务器根据终端的设备标识(Device ID)计算hash值，选取一个注册服务器，其ID值与终端的hash值接近，将该ID值与hash最接近的注册服务器分配给终端。
步骤606、接入服务器向终端发送返回消息，返回消息携带该ID值与hash最接近的注册服务器的IP地址和步骤605中计算得到的hash值。
这里，终端后续通过该IP地址查询到该注册服务器，以便能向该注册 服务器发起注册消息。
步骤607、终端接收到返回消息后，保存hash值，并向注册服务器进行注册。
步骤608、终端定时发送心跳消息到注册服务器保活，并在心跳消息中带上步骤607保存的hash值。
步骤609、注册服务器发送增加或减少的变化，接入服务器重新为每个注册服务器分配新的ID值。
步骤610、接入服务器发送为每个注册服务器重新分配的一个新的ID值。
步骤611、注册服务器在收到终端发送的心跳消息后，解析心跳消息中的hash值，重新确认hash值是否与本注册服务器的ID是最接近的；如果不是，则执行步骤612；否则，不予处理，保存目前连接。
步骤612、发送心跳回复消息，该消息用于通知终端需要重新注册消息，心跳回复消息中会把新的注册服务器IP地址和hash值返回给终端，同时在内存中删除该终端的相关信息。
步骤613、终端判断比较前后两次得到的hash值(步骤606得到的一个由服务器计算的hash值；以及步骤612得到的一个由注册服务器计算的hash值，且hash值的计算规则一样)，如果一样，则不需要迁移，如果不一样，则需要终端进行数据迁移，则进行数据迁移。
步骤614、终端收到心跳回复消息，该消息用于通知终端需要重新注册消息后，会向新的注册服务器进行注册。
步骤615、发送心跳消息保活。
这里，步骤613可以有，也可以没有；步骤614和步骤615可以同时发生，也可以如目前流程所示存在先后顺序。
在本应用场景采用本发明实施例，对于目前使用多屏业务的用户越来 越多，用户的数据如何在多屏网关系统中进行分布式的有效管理，而不是采用集中式的数据管理方式的问题，提供的数据处理方案是一种分布式的IPTV多屏网关注册服务器终端用户数据动态管理的技术，当注册服务器发生变化时，终端数据能够自动进行迁移，不需要人工进行干预，从而保证了用户服务不受影响，使得系统更加稳定可靠。
