关于群发短信

现在有个疑惑: 如果手机群发短信, 是每条短信单独发RRC conn req, 然后发出短信,释放RRC链接, 还是RRC链接建立起来后, 通过多个DT来把多个短信发出去?
查了查协议,摘录了几段如下。注意我标注的红色字体,应该是取决于UE的实现,两种方法都可以,显然通过同一条RRC连接发送的效率更高,但UE必须遵守协议制定的规则。

If an entity has morethan one short message or notification to send, then it is useful to maintainthe Radio Resource (RR) connection (in A/Gb mode) or the signalling connection(in Iu mode) in between transfers. ......

If another short message or a memoryavailable notification is to be sent, an originating SMR entity in the MS may choose to continue to use the same RR connection (in A/Gb mode) or the signallingconnection (in Iu mode).

......(这里描述UE如何在同一个RR或信令连接上发送多条短消息,比较长,省略。有兴趣者自查协议。)

When an MS sendssuccessive memory available notifications and/or mobile originated shortmessages on different RR connections (in A/Gb mode) or signalling connections(in Iu mode), the MS is strongly recommended to use different TransactionIdentifiers for the old and new MM connections.
