我有 GSM 调制解调器,可以从用户那里获取 SMS/MMS 消息。收到短信时效果很好。但是,如果我收到彩信,PDU 消息(只有没有 UDH 等的用户数据)会变成如下所示:

E706246170706C69636174696F6E2F766E642E7761702E6D6D732D6D65737361676500B487AF848C8298583130333630303030303730353836313330323037313032313535303031008D9083687474703A2F2F6D6D7363723A383030322F30333630303030303730353836313330323037313032313535303031008805810302A300890E802B3739303938363534353735008A808E02018D

然后我尝试将其转换为ANSI(8位八位字节为ANSI符号),因此将其修改为:

00E70006$application/vnd.wap.mms-message000000B4008700AF0084008C00820098X103600000705861302071021550010000008D00900083http://mmscr:8002/036000007058613020710215500100000088000500810003000200A300000089000E0080+790986545750000008A0080008E00020001008D

在我看来转换是错误的!如何正确转换并使用这种消息?提前致谢。
