Claim:
1. A communication method, comprising: broadcasting, by the base station, licensed band idle resource information regarding licensed band resources dedicated to use in opportunistic spectrum access mode for detection by multimode terminals in need of opportunistic spectrum access; allocating, by a base station to a first multimode terminal, a licensed band resource for use by the first multimode terminal in an opportunistic spectrum access mode after broadcasting the licensed band idle resource information, wherein before allocating the licensed band idle resource and/or the preset licensed band resource dedicated to use in the opportunistic spectrum access mode, the method further comprises receiving, by the base station from the first multimode terminal, a licensed band idle resource request and/or a request for a licensed band resource dedicated to use in the opportunistic spectrum access mode; sending, by the base station to the first multimode terminal, information about the licensed band resource for use by the first multimode terminal in the opportunistic spectrum access mode, wherein the licensed band resource is used for the first multimode terminal to communicate with a second multimode terminal using an unlicensed band protocol standard; and sending, by the base station, information that the first multimode terminal works in the opportunistic spectrum access mode to a target base station when the first multimode terminal is handed over so that the target base station allocates the first multimode terminal a licensed band resource for use by the first multimode terminal in the opportunistic spectrum access mode.
