Abstract:
1. A dynamic spectrum allocation method, comprising: receiving a bandwidth request message sent by a base station, wherein the bandwidth request message includes radio frequency capabilities of the base station, a bandwidth requirement on unauthorized bands of the base station, and a set of authorized bands of the base station, wherein the set of authorized bands of the base station comprises at least one of the following: a set for a first authorized band that share radio frequency capabilities with the unauthorized bands and are aggregated and dynamically available on the base station, and a set for a second authorized band that share no radio frequency capability with the unauthorized bands and are aggregated and dynamically available on the base station; determining a spectrum allocation scheme according to the radio frequency capabilities of the base station, the bandwidth requirement on the unauthorized bands of the base station, the set of authorized bands of the base station, and an obtained set of unauthorized bands that are currently idle; and sending a bandwidth request response message including the spectrum allocation scheme, wherein the spectrum allocation scheme is used to indicate information of an unauthorized band allocated to the base station, and indicate need of aggregating a bandwidth requirement on at least one authorized band in the set of authorized bands of the base station to the unauthorized band allocated to the base station.
