Differences between Tianyi Gateway 2.0 and 3.0

To put it simply, the biggest difference between Tianyi Gateway 2.0 and 3.0 is that 3.0 adds LinkID. In the process of using the network, we usually use the gateway protocol of China Mobile the most. This gateway protocol is abbreviated as CMPP, and there are two versions of CMPP, one is version 2.0 and the other is version 3.0. The biggest difference between CMPP2.0 and 3.0 is that LinkID is added in 3.0. It is worth mentioning that version 3.0 has been optimized, and the definition of user number has been added on FEE _ TERM _ TYPE, DEST _ TERM _ TYPE and SRC _ TERM _ TYPE. When the user number type is 0, it means that this is a group of real numbers, and when the user number type is 1, it means that this is an anti-counterfeiting number, as can be seen from the added information. In fact, LinkID is a temporary sign of subscription relationship. Only when users can accept short messages normally can a normal subscription relationship be established, and the sent short messages can only be recharged successfully with LinkID, otherwise the authorization will fail. Generally speaking, this is also a protective measure to technically prevent SP from sending out charging information indiscriminately.
