Abstract

A channel occupying method is disclosed by the present invention. Channel occupying periods are configured in advance in an internal AP, each of the channel occupying periods includes a first period, and the first period includes an AP occupying channel period; when the internal AP detects a starting end of the AP occupying channel period, the internal AP occupies a channel alone in the AP occupying channel period to perform data transmission. Meanwhile, a mobile AP and an external STA are further disclosed by the present invention, and the method and the apparatuses disclosed by the present invention are adopted to increase the data transmission rate of the internal AP.

Claims

1. A channel occupying method, applied to a mobile AP comprising an internal access point AP and an internal station STA, wherein the method comprises:

configuring channel occupying periods in the internal AP in advance, each of the channel occupying periods comprises a first period, and the first period comprises an AP occupying channel period, and the method further comprises;

when the internal AP detects a starting end of the AP occupying channel period, occupying a channel alone in the AP occupying channel period to perform data transmission.

2. The method according to claim 1, wherein the internal AP is connected to at least one external STA, and the method further comprises:

configuring channel occupying periods in the internal STA and the external STA in advance, wherein each of the channel occupying periods comprises a first period, and the first period further comprises a contention period; and

when the internal STA and the external STA detect a starting end of the contention period, adopting a distributed coordination function DCF method in contention for a channel to perform data transmission in the contention period.

3. The method according to claim 2, wherein the method for configuring the channel occupying periods is:

setting a duration of the AP occupying channel period and a duration of the contention period according to the number of external STAs.

4. The method according to claim 3, wherein when the number of external STAs is one, a ratio of the duration of the AP occupying channel period to the duration of the contention period is 1:

1;

when the number of external STAs is greater than one, a ratio of the duration of the AP occupying channel period to the duration of the contention period is 3;

2.

5. The method according to claim 2, further comprising:

receiving an external instruction, wherein the external instruction is used to indicate a duration of the AP occupying channel period and a duration of the contention period; and

configuring the duration of the AP occupying channel period and the duration of the contention period according to the external instruction.

6. A portable wireless access point AP apparatus, the mobile AP comprising an internal AP and an internal station STA, wherein the internal STA accesses the Internet through an external AP, the internal AP accesses the Internet through the internal STA and an external STA, and the internal AP comprises:

a first configuration module and a first transmission module, wherein

the first configuration module is configured to configure channel occupying periods in the internal AP in advance, each of the channel occupying periods comprises a first period, and the first period comprises an AP occupying channel period; and

the first transmission module is configured to detect the channel occupying period, and when a starting end of the AP occupying channel period in the channel occupying period is detected, occupy a channel alone in the AP occupying channel period to perform data transmission.

7. The apparatus according to claim 6, wherein the internal STA comprises:

a second configuration module and a second transmission module, wherein

the second configuration module is configured to configure channel occupying periods in the internal STA in advance, each of the channel occupying periods comprises a first period, and the first period further comprises a contention period; and

the second transmission module is configured to detect the channel occupying period, and when a starting end of the contention period in the channel occupying period is detected, adopt a distributed coordination function DCF method in contention for a channel in the contention period to perform data transmission.

8. The apparatus according to claim 7, further comprising:

a receiving module, wherein

the receiving module is configured to receive an external instruction, and the external instruction is used to indicate a duration of the AP occupying channel period and a duration of the contention period; and

the first configuration module and the second configuration module configure the duration of the AP occupying channel period and the duration of the contention period according to the external instruction.

9. An external station STA, comprising:

a third configuration module and a third transmission module, wherein

the third configuration module is configured to configure channel occupying periods in the external STA in advance, each of the channel occupying periods comprises a first period, and the first period comprises a contention period; and

the third transmission module is configured to detect the channel occupying period, and when a starting end of the contention period in the channel occupying period is detected, adopt a distributed coordination function DCF method in contention for a channel in the contention period to perform data transmission.
