The embodiment of the invention provides a session processing method and device and communication equipment. The method comprises the steps that an SMF sends a session message to a UPF; wherein the session message comprises an FRER session attribute cell, and the FRER session attribute cell is used for indicating the UPF to execute at least one of the following on messages corresponding to at least two FRER sessions: downlink copying and uplink deduplication; an association relationship exists between the at least two FRER sessions.

This invention belongs to the field of digital control systems for power electronic devices. It provides a high-speed communication system and method for multiple units of CHB frequency converter based on FPGA ping-pong buffer. By building an efficient parallel processing architecture at the FPGA hardware level, it realizes zero-wait instruction issuance and instantaneous status acquisition between the controller and dozens of distributed power units, compressing the system communication and processing time from milliseconds to hundreds of microseconds, achieving the technical effect of CHB frequency converters achieving extremely short control cycles and high dynamic performance.
