Abstract

The present invention relates to the field of communications technologies, and in particular, discloses an automatic cable distribution switch apparatus and system, and an automatic cable distribution switch method. In this solution, the automatic cable distribution switch apparatus is connected to at least two access network devices; even through a terminal cannot gain local power, when needing to switch from a first device, currently connected to the terminal, of an access network to a second device of the access network, the terminal can send an access network device switch instruction to the automatic cable distribution switch apparatus. In this case, when receiving the access network device switch instruction, the automatic cable distribution switch apparatus can switch the terminal from any access network device to another access network device, thereby achieving an effect that automatic cable distribution switch can be performed when the terminal cannot gain local power.
