Claim:
1. An energy-saving control method for a cell in a heterogeneous system, comprising: receiving, by an access control device of a serving cell, a service request of a multi mode user equipment (UE); and when a radio resource of the serving cell cannot satisfy the service request of the multi mode UE, and if the access control device of the serving cell determines that a heterogeneous system neighboring cell of the serving cell is in an energy-saving state, sending, by the access control device of the serving cell, an exit energy-saving state request message to an access control device of the heterogeneous-system neighboring cell, wherein the exit energy-saving state request message is used to request the heterogeneous-system neighboring cell to exit the energy-saving state; sending, by the access control device of the serving cell, instruction information to the multi-mode UE, wherein the instruction information is one of an RRC connection setup reject message and a radio access bearer assignment response message, and includes a wait time for the multi-mode UE to redirect to the heterogeneous-system neighboring cell after exiting the energy-saving state, the wait time being greater than or equal to time for the heterogeneous-system neighboring cell to exit the energy-saving state, and the wait time is used to instruct the multi-mode UE to, when the wait time is due, redirect to the heterogeneous system neighboring cell to request for a service.
