Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In this embodiment, a remote communication module of the acquisition terminal is used as a communication unit on the acquisition terminal, and the remote communication module transmits service data such as received network quality information, address information, device identification information and the like to the eSIM \ SIM card through an APDU instruction, and the eSIM \ SIM caches different types of received data in a memory of the eSIM \ SIM card, and periodically uploads the different types of received data to the value-added server.
Fig. 1 is a flowchart of a method for caching data by a SIM card according to an embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides a method for caching data by a SIM card, where the method includes the following steps:
and S1, determining the data type of the service data received by the SIM card.
For example, it is determined which of network quality information, address information, or device identification information the service data received by the SIM card belongs to. The storage format of the service data in the SIM card includes a data Type, a data Length, and a data Value, and may adopt a TLV format including a Type, a Length, and a Value, and the data Type of the service data may be identified by a Type field.
And S11, judging whether the memory of the SIM card is in the state of uploading data.
For example, it is determined whether the memory of the SIM card is uploading service data to the value added server.
And S2, when the memory is not in the data uploading state, judging whether the memory has data with the same type as the received service data.
For example, the data Type of the service data is identified by the Type field of the service data, so as to determine whether the same data as the received service data Type exists in the memory.
And S21, if the memory does not have the data with the same type as the received service data, storing the received service data into the memory.
For example, the data type of the network quality information is a, the data type of the address information is B, and the data type of the device identification information is C. When the network quality information (A type data) is received, judging that the A type data does not exist in the memory, directly storing the received network quality information (A type data) into the memory, and recording the first address of the A type data. When the address information (B type data) is received, judging that the B type data does not exist in the memory, directly storing the received address information (B type data) into the memory, and recording the first address of the B type data. When the device identification information (C type data) is received, judging that the C type data does not exist in the memory, directly storing the received device identification information (C type data) into the memory, and recording the first address of the C type data.
And S22, if the data with the same type as the received service data exists in the memory, judging whether the storage amount of the data with the same type existing in the memory reaches a preset threshold value. The preset threshold value can be preset according to the actual application requirement.
And S23, if the storage amount of the same type of data existing in the memory reaches a preset threshold value, replacing the earliest existing data of the same type with the received service data and storing the earliest existing data of the same type.
For example, network quality information (a-type data), address information (B-type data), and device identification information (C-type data) already exist in the memory, when the a-type data (Am) is received, it is determined that the a-type data (sequentially stored as A1A2A3 … according to the sequence) already exists in the memory, and the storage amount of the a-type data has reached a preset threshold, the earliest stored a-type data is searched according to the head address of the a-type data recorded in step S21, and A1 is replaced with Am (sequentially stored as AmA2A3 …); when type a data (An) is received again, a2 (stored as AmAnA3 … in turn) is replaced with An, i.e., the oldest data is overwritten with new data.
And S24, if the storage amount of the same type of data existing in the memory does not reach a preset threshold value, storing the received service data to the tail of the existing same type of data.
For example, the memory has network quality information (a type data), address information (B type data), and device identification information (C type data) stored as A1A2A3 … B1B2B3 … C1C2C3 … in sequence according to the sequence, and when receiving the B type data (Bn), it is determined that the B type data exists in the memory, and the storage amount of the B type data does not reach the preset threshold, and the Bn is inserted and stored to the tail of the B type data (sequentially stored as A1A2A3 … B1B2B3 … BnC1C2C3 …).
And S3, judging whether the storage space of the backup memory is full when the memory is in the data uploading state.
And S31, if the storage space of the backup memory is full, replacing the earliest data of the same type in the backup memory with the received service data and storing the earliest data.
And S32, if the storage space of the backup memory is not full, directly storing the received service data to the backup memory.
And S33, after the data uploading of the memory is finished, writing the service data stored in the backup memory into the memory and clearing the service data stored in the backup memory.
The network quality information, the address information, the equipment identification information and other data acquired by the remote communication module of the acquisition terminal are stored in the memory of the SIM card through the steps, and the memory space is shared by various real-time data instead of being stored separately in blocks, so that the space occupied by the whole data storage is reduced. And moreover, the received new data is judged to be stored in the memory or the backup memory according to the reporting state of the data, so that the data loss is prevented when the data are reported.
