An access point (AP), comprising:

• a processor;
• and
• a memory storing instructions executable by the processor,
• wherein the processor is configured to:
• receive parameter information of a current service access category;
• and
• broadcast system information including the parameter information to a station (STA) to enable the STA to transmit current service data according to the parameter information, the parameter information being included in a service type mapping table and a service category mapping table,
• wherein the AP stores the service type mapping table and the service category mapping table, the service type mapping table comprising:
• a current service priority, a current service type, an acronym of the current service type, and a mapping relationship between the current service type and the current service priority, and the service category mapping table comprising:
• the current service priority, the current service access category, transmit queues, designations, and a mapping relationship between the current service priority and the current service access category.
