ESS Communication session delivery method between heterogeneous protocols of ESS controller

摘要

The present invention discloses a communication session transfer method between heterogeneous protocols of an ESS controller. In the communication session delivery method of the present invention, when the ESS controller connects the session in the first communication interface, generating a virtual session with the remaining communication interface, and the ESS controller transfers the communication sequence from the first communication interface to the remaining communication interface. Performing a virtual communication function, the ESS controller switching to any one of the remaining communication interfaces when the first communication interface fails, and the ESS controller communicating the last session connection number of the first communication interface And transferring to the interface and immediately following the last session connection number in the switched communication interface by the ESS controller.
