Abstract: A method for starting inter-frequency measurement is provided. The method is applied to an inter-frequency network, the inter-frequency network includes a first base station and a second base station, there is an overlapping area between a signal coverage area of the first base station and a signal coverage area of the second base station, and an access priority of the second base station is higher than an access priority of the first base station; user equipment accesses the first base station; a distance between the second base station and an AP is less than a first distance threshold, and the AP is controlled by an AC. The method includes: receiving, by the AC, a user authentication request; obtaining an identifier of the user equipment from the user authentication request; and sending an inter-frequency measurement request to the user equipment according to the identifier of the user equipment.

Abstract: The present invention provides a data transmission method, device, and system, and relates to the communications field, which can improve data transmission efficiency. The method includes: determining, by a second base station, that statuses of all HARQ processes in a first hybrid automatic repeat request HARQ buffer are occupied states; and sending, by the second base station, a second data block to a user equipment UE by using an HARQ process in an idle state in a second HARQ buffer, where the first HARQ buffer and the second HARQ buffer are different HARQ buffers disposed in the second base station. The data transmission method, device, and system are applicable to data transmission in carrier aggregation.

Abstract: A method for locating an idle-state user equipment and an apparatus are disclosed. An access network device updates a cell location identifier in a system message to a preset location identifier, and notifies, by using a paging message, idle-state UE in a cell that the system message is changed, so as to trigger the idle-state UE in the cell to read the system message and learn that the cell location identifier is updated. Therefore, the idle-state UE is triggered to initiate a location update process. The access network device locates the idle-state UE in the cell according to the location update process initiated by the idle-state UE in the cell, thereby locating the idle-state UE.

Abstract: Embodiments of the present invention disclose an energy saving method for a wireless AP, including: when it is detected that a time during which a wireless AP transmits no packet uplink or downlink and is associated with no station is greater than a preset time threshold, disabling, by the wireless AP, a transmit channel, and retaining only a receive channel; listening for, by the wireless AP, a Probe Request through the receive channel; and if the Probe Request obtained by listening meets a preset activation condition, enabling, by the wireless AP, the transmit channel. The embodiments of the present invention further disclose a wakeup method for a wireless AP and related devices. By means of the present invention, power consumption of a wireless AP can be effectively reduced.

Abstract: Embodiments of the present invention provide an energy-saving method and apparatus for a heterogeneous network. The energy-saving method for a heterogeneous network includes: performing traffic detection on a cluster, where the cluster includes at least one first network device configured to provide a capacity enhanced network resource; and migrating a service in the cluster to a second network device if traffic of the cluster does not exceed a first preset threshold, and turning off the first network device in the cluster, where the second network device is configured to provide a coverage-type network resource, and network coverage of the first network device is within network coverage of the second network device. By means of the energy-saving method and apparatus for a heterogeneous network that are provided in the embodiments of the present invention, energy-saving processing on a heterogeneous network is implemented and a resource waste is avoided.
