A first base station may perform a method for controlling handover of a terminal. The method may include setting a handover parameter that is determined based on a handover policy and transmitting a message including the handover parameter to the terminal. The handover parameter includes a service parameter. The service parameter is used when determining a handover condition of the terminal in order to induce handover from the first base station to the second base station according to the handover policy.

Method of controlling handover

A smart metering system using a white space band includes a band search sensor installed in a predefined area which scans a digital public broadcast channel band; a band management server which manages area specific broadcast channel status information based on a scanning result obtained by the band search sensor and which searches a white space band that is an idle channel band of a corresponding area based on the broadcast channel status information to allocate the white space band as a smart metering data transmission channel; and a base station which allocates the smart metering data transmission channel from the band management server and which forms a wireless communication channel between a smart meter and a grid central server via the allocated smart metering data transmission channel.
