A wireless access point device, wherein the wireless access point device comprises: a) a first processing module, configured to determine uplink resource scheduling information according to information about station devices associated with the wireless access point device, wherein the uplink resource scheduling information comprises an identifier of each of to-be-scheduled station devices, to-be-scheduled uplink resources, and locations of the to-be-scheduled uplink resources, the to-be-scheduled station devices are multiple devices of the station devices, the identifier is used to indicate that the station device is a device having uplink traffic with frequent small packets, and the uplink traffic with frequent small packets is a predefined service or a service in which a quantity of uplink small packets received by the wireless access point device per unit of time exceeds a preset threshold; and b) a first sending module, configured to send the uplink resource scheduling information determined by the first processing module to the to-be-scheduled station devices; c) the wireless access point device is adapted to schedule the uplink transmission resources for multiple station devices at a time according to identifiers of the station devices, and to deliver information about the resources to to-be-scheduled station devices, characterized by d) wherein uplink transmission data in the service is small packets less than 80 bytes; and e1) wherein the first processing module is specifically configured to: collect statistics on channel information and load information of the station devices associated with the wireless access point device; e2) determine, according to the channel information, a modulation and coding scheme, MCS, supported by the wireless access point device; e3) acquire information about average load of the station devices according to the load information; and e4) determine, according to the MCS and the information about the average load, a size of an uplink resource required by each of the station devices; wherein e5) the first sending module is specifically configured to schedule uplink resources for the station devices according to a sum of uplink resources required by the station devices, wherein the uplink resources are some or all of the to-be-scheduled uplink resources; and f) wherein the first processing module is further configured to: determine, according to load information and QoS requirements of the station devices associated with the wireless access point device, a transmission probability for each of the to-be-scheduled station devices to send uplink data. a) a first processing module, configured to determine uplink resource scheduling information according to information about station devices associated with the wireless access point device, wherein the uplink resource scheduling information comprises an identifier of each of to-be-scheduled station devices, to-be-scheduled uplink resources, and locations of the to-be-scheduled uplink resources, the to-be-scheduled station devices are multiple devices of the station devices, the identifier is used to indicate that the station device is a device having uplink traffic with frequent small packets, and the uplink traffic with frequent small packets is a predefined service or a service in which a quantity of uplink small packets received by the wireless access point device per unit of time exceeds a preset threshold;
