METHOD AND APPARATUS FOR MESSAGE TRANSMISSION

摘要

A method and an apparatus for message transmission, which relate to a communications field, are provided in the embodiments of the present invention. The method includes: receiving an authentication request from a first user equipment, and transmitting, according to a first User Identifier (UID), an authentication request for user binding to a Home Subscriber Server (HSS) for the first user, in order that the HSS for the first user judges, according to a saved binding relationship between an International Mobile Subscriber Identity (IMSI) and the UID, whether a binding relationship between the IMSI of the first user equipment and the first UID is legal; and if the HSS for the first user determines that the binding relationship between the IMSI of the first user equipment and the first UID is legal, downloading the binding relationship between the IMSI of the first user equipment and the first UID from the HSS for the first user, and after establishing communications between the first user equipment and a second user equipment, transmitting a message satisfying the downloaded binding relationship to the second user equipment when receiving the message from the first user equipment. In the present invention, the occurrence of the UID fabrication in the data transmission procedure is prevented, and the security of the data transmission is enhanced.
