Title:
CALLING INFORMATION AUTHENTICATION METHOD, APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/183694
Kind Code:
A1
Abstract:
Disclosed in the present disclosure are a calling information authentication method, apparatus and system, which relate to the technical field of telecommunication network signaling. The method comprises: receiving a first IAM message sent by an LS, wherein the first IAM message comprises calling information; generating a calling signature parameter on the basis of the calling information; adding, to the first IAM message, the calling signature parameter and an SSGW certificate parameter, which is acquired from a CA of the present domain, so as to obtain a second IAM message by means of recombination; and sending the second IAM message to a destination domain, wherein after the destination domain verifies the second IAM message successfully, the calling signature parameter and the SSGW certificate parameter in the second IAM message are removed, so as to generate a third IAM message, and the third IAM message is sent to the next node. By means of the present disclosure, the authenticity, tamper-proof performance and traceability of calling information can be ensured without changing signaling transmitted by existing LSs.
