Abstract

A method can include, in an access point (AP) configured to control data transfers for associated stations (STAs) in time intervals, storing a unique identifier and quality-of-service (QoS) requirement for each STA of a first set in a nonvolatile memory of the AP. In response to a STA associating with the AP, if the associating STA is in the first set, allocating time for the STA in the time intervals to meet the QoS requirement of the STA without receiving transmitted QoS data from the STA, and if the associating STA is not in the first set, establishing a QoS for the STA having a lower priority than any associated STAs of the first set. Corresponding systems and devices are also disclosed.

Claims (47)

1. A method, comprising:

in an access point (AP) configured to control data transfers for associated stations (STAs) in time intervals,

storing STA values for a set of STAs in a nonvolatile memory of the AP, the STA values of the set including, for each STA

a unique identifier for each STA, and

a quality-of-service (QoS) requirement for the STA;

associating with a STA;

determining if a unique identifier of the associated STA from the associated STA; and

in response to the unique identifier of the associated STA being included in the first set, allocating time for the associated STA in the time intervals to meet the QoS requirement of the associated STA without receiving transmitted QoS data from the associated STA,

in response to the unique identifier of the associated STA not being in at least the first set, negotiating with the associated STA to establish a negotiated QoS for the associated STA.

2. The method of claim 1 , wherein the unique identifier for each STA comprises a media access control (MAC) address.

3. The method of claim 1 , wherein the QoS requirement for each STA comprises a bandwidth requirement.

4. The method of claim 1 , wherein the AP is compatible with at least one IEEE 802.11 wireless standard.

5. The method of claim 1 , wherein the negotiated QoS has a lower priority than any STAs of the set.

6. The method of claim 1 , further wherein negotiating with the associated STA includes, in response to determining that the QoS requirement of the associated STA can be met without impacting the QoS of the STAs of the set, allocating time for the associated STA in the time intervals to meet the QoS requirement of the associated STA.

7. The method of claim 1 , further including in response to the unique identifier of the associated STA being included in the set, and the current bandwidth of the AP being insufficient to meet the QoS of the associated STA, disconnecting a STA having a unique identifier that is not included in the set.

8. An access point (AP) device for a wireless communication system, comprising:

nonvolatile memory circuits configured to store a parameter block with parameters for each of a plurality of stations (STAs) of a set, including for each STA of the set,

a unique identifier, and

a quality-of-service (QoS) requirement; and

wireless communication circuits configured to control data transfers for associated STAs in time intervals, and including

a conditional allocation section configured to

associate with a STA,

determine if the associated STA is in the set,

in response to the associated STA being in the set, allocating time for the associated STA in the time intervals to meet the QoS requirement of the associated STA without receiving transmitted QoS data from the associated STA, and

in response to the associated STA not being in the set, negotiating with the associated STA to establish a negotiated QoS for the associated STA.

9. The AP device of claim 8 , wherein the unique identifier for each STA comprises a media access control (MAC) address.

10. The AP device of claim 8 , wherein the QoS requirement for each STA comprises a bandwidth requirement.

11. The AP device of claim 8 , wherein the wireless communication circuits are compatible with at least one IEEE 802.11 wireless standard.

12. The AP device of claim 8 , wherein the conditional allocation section configured to, in response to the unique identifier of the associated STA not being in at least the first set, negotiate a QoS for the associated STA that has a lower priority than the QoS requirements for the STAs of the set.

13. The AP device of claim 8 , wherein: the conditional allocation section is configured to, if the associated STA is not in the set and the QoS requirement of the associated STA can be met without impacting the QoS of the STAs of the set, allocate time for the associated STA in the time intervals to meet the QoS requirement of the associated STA.

14. The AP device of claim 8 , wherein the conditional allocation section is configured to, in response to the unique identifier of the associated STA being included in the set, and the current bandwidth of the AP being insufficient to meet the QoS of the associated STA, disconnecting a STA having a unique identifier that is not on included in the set.

15. A system, comprising:

a plurality of first type stations (STAs) configured for wireless communication, each STA including a unique identifier; and

an access point (AP) configured to control data transfers for associated stations in time intervals, the AP including

nonvolatile memory circuits configured to store a parameter block with parameters for a set STAs, including for each STA of the set,

a unique identifier for the STA, and

a quality-of-service (QoS) requirement for the STA, and

wireless communication circuits configured to, in response to a STA associating with the AP, control data transfers for associated STAs in time intervals, including

in response to the associating STA being in the set, allocating time for the associating STA in the time intervals to meet the QoS requirement of the associating STA without receiving transmitted QoS data from the STA, and

in response to the associating STA not being in the set, negotiating with the associating STA to establishing a negotiated QoS for the associated STA.

16. The system of claim 15 , wherein the unique identifier for each STA comprises a media access control (MAC) address.

17. The system of claim 15 , wherein the wireless communication circuits are compatible with at least one IEEE 802.11 wireless standard.

18. The system of claim 15 , wherein:

the STAs of the set comprise built-in STAs that are built into a larger system.

19. The system of claim 15 , wherein the larger system comprises an automobile system.

20. The system of claim 15 , wherein:

the larger system is configured to add STAs that are not built into the larger system to the set.
