Description

Smart electric meter eSIM seed number batch downloading method, medium and terminal Technical Field The invention belongs to the technical field of intelligent electric meters, and particularly relates to a method, medium and terminal for downloading eSIM seed numbers of intelligent electric meters in batches. Background Along with the increasing use of the eSIM technology on electronic products, all power companies in the world also gradually require that a 4G module on a smart meter has an eSIM function, but before the use, the eSIM function of the 4G module on the smart meter needs to preset a seed number when an eSIM card leaves a factory in a factory, so that the power company can have an initial flow number to connect with an SM-dp+ server of a telecom operator when the service number is downloaded. Because the SM-DP+ server downloads the SGP.22 protocol specification of the GSMA followed by the Profile configuration file of the seed number, each seed number needs to have uniqueness in the same area, the seed number is downloaded from the DP+ server of the operator through a unique link address, and the intelligent meter performs the operation of downloading and presetting the seed numbers of the eSIM one by one in the actual production process. The existing method for downloading the seed numbers of the eSIM is to input an independent link address of each seed number on an interface of the electric energy meter through software provided by an operator after the electric energy meter is connected with a communication channel, communicate with a DP+ server of a provider, preset seed number related data into a 4G module of the intelligent electric energy meter, and not have the possibility of actual operation of a production line of the intelligent electric energy meter because the process of the method needs continuous interaction and large data volume, and cannot download in batches.
