The invention provides a remote firmware upgrading method and system for communication equipment. The remote firmware upgrading method comprises the following steps: receiving an upgrading data packet which is transmitted by a service platform, wherein the upgrading data packet which is transmitted by the service platform comprises a firmware code identifier, a version number and a first verification code of upgrading firmware; acquiring firmware corresponding to the firmware code identifier and the version number from the service platform according to the received upgrading data packet, and verifying the acquired firmware to obtain a second verification code; if the first verification code is consistent with the second verification code, performing firmware upgrading. According to the remote firmware upgrading method and system, remote firmware upgrading of communication equipment can be realized; the firmware of each piece of communication equipment is not required to be upgraded to the site gradually in a manual mode. Therefore, the trouble that a specially-assigned person goes to the site personally for upgrading is avoided by using the remote firmware upgrading system and method; the labor cost can be reduced; the upgrading efficiency can be improved.
