多播广播业务流的管理方法和基站
技术领域 本发明涉及通信领域, 具体而言, 涉及啟波存取全球互通 (Worldwide Interoperability for Microwave Access , 简称为 WiMAX )网络中多播广播业务 流的管理方法和基站。 背景技术 宽带无线接入 WiMAX技术是基于无线城域网美国电子和电子工程师协 会 ( Institute of Electrical and Electronics Engineers , 简称 IEEE ) 802.16标准 的宽带无线技术。目前出现了先进基站( Advanced Base Station,简称为 ABS ), 先进基站能够兼容传统终端, 同样地, 先进终端 ( Advanced Mobile Station, 简称为 AMS )也应该能够接入传统基站。 先进基站的时间区域( Time Zone ) 可以分成两个区 i或,即第一区或(也称为先进区 i或, 16m Zone,简称为 MZone ) 和第二区域 (也称为传统区域, Legacy Zone, 简称为 LZone )。 先进终端可 以工作在第一区域, 或者转换为传统终端的工作方式工作在第二区域。 支持多载波的先进终端可以分为单通道 (single radio ) 终端和多通道 ( multiple radio ) 终端两种。 一个通道对应于物理层的一个射频模块 ( Radio Frequency, 简称为 RF ), —个通道可以工作在系统的一个载波频点上。 支持多载波的先进基站的载波可以分为全配置载波和部分配置载波。 全 配置载波是指配置了所有控制信道的载波, 包括同步信道、 广播信道、 组播 信道和单播信道,还包括与多载波操作及其他载波的信息和参数相关的信道。 部分配置载波是指只配置了在多载波操作中用于支持业务交互的基本的控制 信道的载波。 全配置载波可以作为支持多载波的终端的主载波或者辅载波, 部分配置载波仅可以作为上述终端的辅载波。 每个支持多载波的终端只能有 一个主载波, 可以有一个或多个辅载波, 也可以没有辅载波。 支持多载波的 终端如果使用辅载波, 基站需要为其分配辅载波, 后续根据其的业务情况激 活辅载波。 对于支持多载波的终端, 规定了如下两种操作模式: 载波聚合和载波转 换。 载波聚合是指, 上述终端总与其主载波保持物理连接并监控其上传输的 控制信息, 载波转换是指, 终端通过基站的指示信息, 将其物理连接由主载 波转换至辅载波, 在与辅载波连接后, 该终端无需维持与其主载波的物理连 接, 只需根据预先设置的周期或者触发条件返回主载波。 多播广播业务 ( Multicast Broadcast Service, MBS )是在移动网络中提供 一个数据源向多个用户传送数据的点到多点业务, 能够实现网络资源共享, 提高网络资源、 特别是空中接口资源的利用率。 基于 WiMAX的 MBS业务 支持两种接入模式: 单基站接入和多基站接入。 在多基站接入模式下, 存在 MBS域 ( MBS zone )的 ^既念, 即一组基站的集合, 每个 MBS zone对应一个 MBS zone标识( MBS zone ID ), —个基站可以同时属于多个 MBS zone。 每 个 MBS zone可以提供多个 MBS业务( MBS service ), 在最新的 WiMAX先 进系统中, 通过多播连接标识 (Multicast Station ID, 简称为 MSTID ) 指示 多播连接。 先进基站需要支持增强型的多播广播业务 (Enhanced MBS , 简称为 E-MBS ), 即系统既需要实现高速多媒体业务的多播广播, 同时还需要减小 终端的功耗。 因此, 可以将多载波和 E-MBS 结合, 以达到高吞吐量、 高速 率的要求。 多载波上承载 E-MBS业务的方式有两种: 一种是专用载波方式, 即 E-MBS 业务独占某个载波上的所有时频资源; 另一种方式是混合载波方 式, 即 E-MBS业务与单播业务共享载波上的时频资源。 多个 E-MBS域的多 个 E-MBS 业务在系统支持的多个载波上可以任意分配, 因此, 如何针对多 载波系统特点, 完成多播广播业务流的建立、 更改, 并且合理地在多个载波 上发送 E-MBS相关控制信息, 既保证终端的节电需求, 同时减小信令开销, 是在多载波下发送多播广播业务亟待解决的问题。 发明内容 本发明要解决的技术问题是提供一种多播广播业务流的管理方法和基 站, 从而达到降低终端操作复杂度、 减小系统信令开销的目的。 为了解决上述问题, 本发明提供了一种多播广播业务流的管理方法, 包 括: 基站发送业务流建立消息为终端建立多播广播业务流;
