Embodiment Construction

[0039] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0040] In this embodiment, the remote communication module of the collection terminal is used as a communication unit on the collection terminal, and the remote communication module transmits received service data such as network quality information, address information, and device identification information to the eSIM\SIM card through APDU instructions, The eSIM\SIM buffers the received data of different types in the memory of the eSIM\SIM card, and uploads it to the value-added server periodically.

[0041] figure 1 It is a flowchart of a method for caching data in a SIM card provided in an embodiment of the present invention. like figure 1 As shown, the e...

Abstract

The present invention relates to the technical field of communication, and discloses a method for caching data of a user identity card, the method comprising: determining the data type of service data received by the user identity card; When there is data of the same type as the received service data, storing the received service data in the memory; there is a service data of the same type as the received service data in the memory of the user identity identification card When the data is stored, the received service data is stored at the end of the existing data of the same type or the received service data is replaced by the earliest existing data of the same type and stored. The present invention caches the received service data in the memory of the user identity identification card in a shared manner, thereby reducing the storage space occupied by the overall data.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method for caching data of a user identity identification card and a user identity identification card. Background technique [0002] A large number of wireless public network remote communication modules and supporting SIM (Subscriber Identity Module, user identification module) cards or eSIM cards (Embedded-SIM, embedded SIM cards) are used in the electricity collection system in the electric power industry. The remote communication module of the collection terminal is used as a communication unit on the collection terminal. The existing technology is to link the collection terminal with the main station through the public network, and the meter reading collected by the collection terminal is collected by the remote communication module of the collection terminal and the supporting SIM card. The data is passed to the master station. In the process of data transmission...
