PS业务有几种类型比如交互类背景类.
如果开始用户申请RRC建立的类型是Originating Interactive Call（主叫交互类） 浏览网页用户在浏览网页，如果这是用户要进行网上视频业务是不是要再次申请一个Originating Streaming Call（主叫流类）业务，很晕啊因为早上看到一个用户申请两次PS业务一次好像是交互类一个是背景类，把我搞晕了，我就想问比如交换累和背景类以及流类都是PS业务那么用户第一次建立RRC是建立其中一种业务，比如用户用上网卡上网可能开始是浏览网页，然后他等一下会发个邮件，然后可能又会来个视频，那么是不是过程会建立几次业务，还是说只是第一次业务的基础上后面几次都纳入第一次业务中，晕晕晕啊
坐等学习啊，我也不知道，新人。。
大至分为会话类（语音）、交互类（网游）、背景类（网页浏览）、流类（音视频流）。以申请RRC连接所触发的业务类型。如果接入后需求的速率有变化系统会跟进业务量的大小进行调速。
一个UE同时只能建立一个RRC连接，多个RAB可以在这个RRC连接上承载。
我们看实际的组合业务时，会发现在RRC不释放的情况下进行的第二次业务申请。
