Description
Technical Field

Background
The MT2621 is a dual-mode internet of things chip (SoC) system supporting NB-IoT (narrowband internet of things) specification. The chip system supports two network modes of NB-IoT and GSM/GPRS, has the advantages of low power consumption and low cost, and can be applied to wearable equipment, Internet of things safety equipment, intelligent electric meters and various industrial applications. Data communication between the two modes becomes an important issue in various applications of the system. For example, when the NB-IoT terminal is used as a master control, the 2G terminal may obtain some information, such as battery voltage, base station information, WIFI information, sensor information, and the like, which needs to be transmitted from the 2G terminal to the NB-IoT terminal, and then uploaded to the IoT server via the NB-IoT terminal narrowband internet of things, so that the server monitors and displays the current module state; meanwhile, if an issuing command is issued by the IoT server, the IoT server can also issue the command to the NB-IoT end through the network, and the NB-IoT end transmits the command to the 2G end to set, execute and the like.

The inventor finds that in the original system inter-process communication mechanism (Ipc) framework, a Socket agent (Socket agent) module exclusively occupies a multiplexing channel and switches the multiplexing channel to a Data Mode (Data Mode) during power-on initialization, and the inter-process communication mechanism module (Ipc) defines a unique Field number (Field ID) in the Socket agent (Socket agent) module. The Socket agent (Socket agent) receives the data packet, checks the field number of the data packet, and distributes the data packet to the interprocess communication module if the data packet belongs to the interprocess communication. The inter-process communication module allocates a process number ID to each user, and the ID uniquely identifies the corresponding user. Inter-process communication (IPC) distributes packets to remote users according to the corresponding serial numbers ID, and if the IDs are not matched, the packets are discarded. If the transmitted data structure is complex and diversified, the calling is repeated frequently, and the specific content is updated continuously, the existing interface of the Ipc is directly called, so that the requirement cannot be met.
In order to overcome the problems, the invention provides a data communication method between dual-mode systems, which adopts an independently operated task to manage the sending and receiving of data, so that the sending and receiving processes of data sending can be orderly and stably realized in a queue mode according to a defined data transmission protocol, and the stability of system communication is improved.
