1. A method for acquiring a network topology, the method being applied to an indoor distribution system, the indoor distribution system comprising: a host unit, the host unit being connected to at least one branch of extended unit, each branch of extended unit comprising at least one extended unit, extended units in a same branch of extended unit being successively cascaded, part or all of the extended units in each branch of extended unit being respectively connected to at least one radio frequency subsystem, each radio frequency subsystem comprising at least one remote unit;
the method comprising:
receiving, by the host unit, position information transmitted by each extended unit connected to the host unit, wherein the position information transmitted by each extended unit connected to the host unit comprises: first-level information respectively corresponding to all extended units in a branch where the extended unit connected to the host unit is located, and second-level information respectively corresponding to part or all of the extended units in the branch where the extended unit connected to the host unit is located, the second-level information comprising gain control values of remote units in the at least one radio frequency subsystem connected to the extended units; and
determining, by the host unit, a network topology structure according to the position information transmitted by each extended unit connected to the host unit.
