Research on Automatic Device Detection Service Implementation Mode

In view of the fact that sometimes the network is unreasonable and users cannot use certain mobile services, this paper studies the standard service-automated device detection ADD service based on the 3GPP protocol and discusses two implementations of the ADD service: based on the home location register HLR (Home The implementation of Location Register) is based on the implementation of EIR (Equipment Identity Register) and compares these two types of services. Operators can decide to deploy in the same way based on their actual network conditions.
