背景技术
短信息中心(SMSC)本身处于2/3G核心网，其与4G、5G核心网传递短消息时，需借助各类核心网专门的短消息传递网元做为中转。2/3G之间与4G之间的短消息中继网元称为IP短信息网关(IP-SM-GW)，2/3G与5G之间的短消息中继网元称为短信息服务功能(SMSF)。在进行信息发送时，短信息中心并不主动识别发送信息的目标终端的网络归属，因此，短信息中心需要发送查询信息至归属位置寄存网元(HLR)查询目标终端对应的路由信息，若需发送大量的短信息时，会加重归属位置寄存网元(HLR)的负担，以及降低发送短信息的效率。

通过在注册中心查询目标终端是否附着网元或网关，以及在目标终端附着网元或网关的情况下，能够根据注册中心确定的终端附着信息向目标终端发送目标信息，避免了发送信息时需要在归属位置寄存网元查询目标终端的路由信息，从而减轻了归属位置寄存网元的负担，以及能够通过物联网信息中心直接向信息发送至目标终端归属的网元中，提升了信息发送的效率。
