Method, device and system for realizing machine-card pool binding

Abstract

The disclosure discloses a method, device and system for realizing machine-card pool binding, and relates to the communication field of the Internet of Things. The method includes: acquiring the terminal's communication card identifier and device identifier through the Sy interface with the PCRF, wherein the PCRF maps the terminal's communication card identifier and device identifier to the Sy interface after receiving the terminal's session access request; according to the terminal The corresponding relationship between the associated communication card identification pool and the equipment identification pool, and verify the binding relationship between the communication card identification and the equipment identification; map the verification result to the Sy interface, so that the PCRF can determine whether the terminal is allowed to use the data according to the verification result business. The disclosure can trigger the realization of the N:N machine-card pool binding function service without increasing the core network business processing load, and prevent illegal devices or communication cards from accessing the network.

Description

technical field [0001] The present disclosure relates to the communication field of the Internet of Things, and in particular to a method, device and system for realizing machine-card pool binding. Background technique [0002] China's Internet of Things has increased significantly from 170 billion yuan in 2009 to more than 750 billion yuan in 2015, with a compound annual growth rate of more than 25%. At the end of 2016, the number of mobile Internet of Things connections was 140 million, of which the number of terminals for machine-to-machine (M2M) applications exceeded 100 million, accounting for 31% of the global total. As a domestic full-service operator, China Telecom will have huge room for development in the Internet of Things industry. At present, China Telecom's IoT mobile network is divided into a provincial network and a private network. The provincial network relies on the deployment of large network elements and mainly provides wireless access and core network ...

Problems solved by technology

However, as IoT companies use a large number of outdoor unattended IoT devices, enterprise customers have applied for a large number of communication cards from operators and purchased a large number of IoT communication modules. If the original IMSI and IMEI are used 1:1 or 1 : N binding, when there is a temporary change between the terminal and the card, it must be changed through the operator's network equipment, which increases the complexity of automatic control for enterprise customers
