## Abstract

Involved in the present disclosure are an information broadcast method and device, a service implementation method and device, an access point, a station, and a computer readable storage medium. The information broadcast method includes: receiving parameter information of a current service access type; broadcasting system information carrying the parameter information to a station (STA) so that the STA transmits current service data according to the parameter information. According to embodiments of the present disclosure, by receiving parameter information of a current service access type and broadcasting the system information carrying the parameter information to an STA, the STA can transmit current service data according to the parameter information, so that a current service such as a real-time game can be supported better.

## Claims

### Claim 1

An information broadcast method, applied to an access point (AP), comprising:
receiving parameter information of a current service access category; and
broadcasting 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.

### Claim 2 (depends on 1)

The method of claim 1, wherein the broadcasting the system information including the parameter information to the STA comprises:
broadcasting the system information including the parameter information to the STA through a beacon.

### Claim 3 (depends on 1)

The method of claim 1, wherein the parameter information comprises at least one of: a size of a contention window, or a transmission duration.

### Claim 4

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.

### Claim 5 (depends on 4)

The AP of claim 4, wherein the processor is further configured to:
broadcast the system information including the parameter information to the STA through a beacon.

### Claim 6 (depends on 4)

The AP of claim 4, wherein the parameter information comprises at least one of: a size of a contention window, or a transmission duration.
