Design and Implementation of LPA for Energy Meter Communication
The development of communication terminals has put forward higher requirements for the application of mobile communication user identification modules(SIM).Embedded SIM(eSIM)is gradually promoted and applied in communication terminals due to its better flexibility and applicability.Based on the characteristics and functions of eSIM Local Profile Agent(LPA),a processing flow and solution for energy meter LPA are designed for the application of eSIM in energy meter communication.The operation and management of configuration files are achieved through the coop-eration of upper computer software with the Profile server,energy meter processing program,meter communication mod-ule,and eSIM.The running results indicate that implementing this processing scheme according to the processing flow can easily complete remote configuration of eSIM local configuration files.The successful implementation of this scheme is of great significance for reducing the cost of smart energy meters,facilitating users to switch operators,improving the communication reliability of smart energy meters,and enhancing the wireless communication management level of the smart energy meter industry.
