Abstract
Various embodiments comprise systems, methods, architectures, mechanisms and apparatus providing improved National Security and Emergency Preparedness (NS/EP) Priority Services mechanisms within the context of IEEE 802.11-type networks.
Claims23
A method for reducing network services provided to non-priority stations (STAs) via an 802.11 access point (AP) STA configured to provide services to priority STAs and non-priority STAs, comprising:
- receiving, at a non-priority STA in communication with an AP STA via a communication channel, a message from the AP STA;
- in response to the received message including a dot11priorityAccessAssertion information element (IE) including a dot11priorityAccessEnforced field, causing the non-priority STA to refrain from accessing the communication channel for an amount of time indicated by a duration value in a durationOfdot11prioriyAccessEnforced field of the dot11priorityAccessAssertion IE;
- and
- in response to the received message including a dot11priorityAccessAssertion IE including an allowedCAPCduringpriorityAccess field, causing the non-priority STA to refrain from accessing the communication channel for an amount of time indicated by a duration value in a durationOfdot11prioriyAccessEnforced field of the dot11priorityAccessAssertion IE, causing the non-priority STA to refrain from accessing the communication channel if a target wake time (TWT) of the non-priority STA is not expiring during a current channel occupancy times (COT).

A method for supporting priority services at an 802.11 access point (AP) station (STA), comprising:
- at an AP STA, entering a priority service mode and determining an amount of service reduction to impose upon non-priority non-AP STAs in communication with the AP STA;
- transmitting, toward non-AP STAs in communication with the AP STA, one or more messages including a dot11priorityAccessAssertion information element (IE) including a dot11priorityAccessEnforced field and a durationOfdot11prioriyAccessEnforced field, and configured to cause a receiving non-priority STA to refrain from accessing a respective communication channel for an amount of time indicated by a duration value in the durationOfdot11prioriyAccessEnforced field;
- and
- including in the dot11priorityAccessAssertion IE of the one or more messages an allowedCAPCduringpriorityAccess field configured to cause a receiving non-priority STA to refrain from accessing the communication channel if a target wake time (TWT) of the non-priority STA is not expiring during a current channel occupancy times (COT).

A method for supporting priority services at an 802.11 access point (AP) station (STA), comprising:
- at an AP STA, entering a priority service mode and determining an amount of service reduction to impose upon non-priority non-AP STAs in communication with the AP STA;
- transmitting, toward non-AP STAs in communication with the AP STA, one or more messages including a dot11priorityAccessAssertion information element (IE) including a dot11priorityAccessEnforced field and a durationOfdot11prioriyAccessEnforced field, and configured to cause a receiving non-priority STA to refrain from accessing a respective communication channel for an amount of time indicated by a duration value in the durationOfdot11prioriyAccessEnforced field;
- and
- transmitting, toward non-AP STAs in communication with the AP STA, a message announcing an availability of one or more resource units (RUs) within an UL-OFDMA frame, and including a predetermined value stored in an AID12 field and configured to cause non-priority non-AP STAs to refrain from reporting data within advertised RUs.
1 more element
A system, comprising:
- at least one 802.11 access point (AP) station (STA) configured to provide network services to a respective plurality of non-AP STAs;
- at least one AP STA, in a priority service mode of operation, transmitting toward respective non-AP STAs in communication with the AP STA, one or more messages including a dot11priorityAccessAssertion information element (IE) including a dot11priorityAccessEnforced field and a durationOfdot11prioriyAccessEnforced field, and configured to cause a receiving non-priority STA to refrain from accessing a respective communication channel for an amount of time indicated by a duration value in the durationOfdot11prioriyAccessEnforced field;
- and
- at least one AP STA, in the priority service mode of operation, including in the dot11priorityAccessAssertion IE of the one or more messages an allowedCAPCduringpriorityAccess field configured to cause a receiving non-priority STA to refrain from accessing the communication channel if a target wake time (TWT) of the non-priority STA is not expiring during a current channel occupancy times (COT).
1 more element
A system, comprising:
- at least one 802.11 access point (AP) station (STA) configured to provide network services to a respective plurality of non-AP STAs;
- at least one AP STA, in a priority service mode of operation, transmitting toward respective non-AP STAs in communication with the at least one AP STA, one or more messages including a dot11priorityAccessAssertion information element (IE) including a dot11priorityAccessEnforced field and a durationOfdot11prioriyAccessEnforced field, and configured to cause a receiving non-priority STA to refrain from accessing a respective communication channel for an amount of time indicated by a duration value in the durationOfdot11prioriyAccessEnforced field;
- and
- at least one AP STA, in the priority service mode of operation, transmitting toward non-AP STAs in communication with the AP STA, a message announcing an availability of one or more resource units (RUs) within an UL-OFDMA frame, and including a predetermined value stored in an AID12 field and configured to cause non-priority STAs to refrain from reporting data within the one or more RUs.
1 more element
A tangible and non-transient computer readable storage medium storing instructions which, when executed by a computer, adapt the operation of the computer to provide a method for supporting priority services at an 802.11 access point (AP), comprising:
- at an AP STA, entering a priority service mode and determining an amount of service reduction to impose upon non-priority non-AP STAs in communication with the AP STA;
- transmitting, toward non-AP STAs in communication with the AP STA, one or more messages including a dot11priorityAccessAssertion information element (IE) including a dot11priorityAccessEnforced field and a durationOfdot11prioriyAccessEnforced field, and configured to cause a receiving non-priority STA to refrain from accessing a respective communication channel for an amount of time indicated by a duration value in the durationOfdot11prioriyAccessEnforced field;
- and
- transmitting, toward non-AP STAs in communication with the AP STA, a message announcing an availability of one or more resource units (RUs) within an UL-OFDMA frame, and including a predetermined value stored in an AID12 field and configured to cause non-priority non-AP STAs to refrain from reporting data within advertised RUs.
