Abstract
A methods and apparatus may be used for accelerated link setup. A method may include a station (STA) acquiring information about an access point of an Institute of Electrical and Electronics Engineers (IEEE) 802.11 network in advance through a previously connected IEEE 802.11 interface and/or an interface other than the IEEE 802.11 network. The STA may use the acquired information during a link setup procedure between the STA and the access point. The information may include a suggestion for a specific procedure to complete the link setup procedure between the STA and the access point.
Claims20
A method for use in an access point (AP), the method comprising:
- receiving a probe request frame that includes a system configuration identifier;
- determining whether the received system configuration identifier matches a stored system configuration identifier;
- on a condition that the received system configuration identifier matches a stored system configuration identifier, transmitting a reduced probe response frame in response to the probe request frame;
- and
- on a condition that the received system configuration identifier does not match any stored system configuration identifier, transmitting a full probe response frame in response to the probe request frame.
An access point (AP) comprising:
- a receiver configured to receive a probe request frame that includes a system configuration identifier;
- a processor configured to determine whether the received system configuration identifier matches a stored system configuration identifier;
- a transmitter configured, on a condition that the received system configuration identifier matches a stored system configuration identifier, to transmit a reduced probe response frame in response to the probe request frame;
- and
- the transmitter is further configured, on a condition that the received system configuration identifier does not match any stored system configuration identifier, to transmit a full probe response frame in response to the probe request frame.
A method for use in a non-access point (non-AP) station (STA), the method comprising:
- transmitting, to an access point (AP), a probe request frame that includes a system configuration identifier;
- receiving, on a condition that the transmitted system configuration identifier matches a system configuration identifier stored in the AP, a reduced probe response frame in response to the probe request frame;
- and
- receiving, on a condition that the transmitted system configuration identifier does not match any system configuration identifier stored in the AP, a full probe response frame in response to the probe request frame.
A non-access point (non-AP) station (STA), comprising:
- a transmitter configured to transmit, to an access point (AP), a probe request frame that includes a system configuration identifier;
- a receiver configured to receive, on a condition that the transmitted system configuration identifier matches a system configuration identifier stored by the AP, a reduced probe response frame in response to the probe request frame;
- and
- the receiver further configured to receive, on a condition that the system configuration identifier does not match any system configuration identifier stored by the AP, a full probe response frame in response to the probe request frame.
A method for use in a non-access point (non-AP) station (STA), the method comprising:
- receiving, from an access point (AP), a system configuration identifier comprising a configuration change count (CCC) value, wherein the CCC value is an integer value that represents a configuration instance;
- determining, by the non-AP STA, whether there is a configuration instance entry in a database associated with the AP;
- on a condition that there is no configuration instance entry in the database associated with the AP, creating a new configuration instance entry associated with the AP and the received CCC value;
- on a condition that there is a configuration instance entry associated with the AP in the database, determining whether the received CCC value matches a CCC value stored in the configuration instance entry associated with the AP;
- and
- on a condition that the received CCC value does not match any CCC value stored in the configuration instance entry associated with the AP, updating the configuration instance entry associated with the AP based on the received CCC value.
A non-access point (non-AP) station (STA) comprising:
- a receiver configured to receive, from an access point (AP), a system configuration identifier comprising a configuration change count (CCC) value, wherein the CCC value is an integer value that represents a configuration instance;
- a processor configured to determine, by the non-AP STA, whether there is a configuration instance entry in a database associated with the AP;
- the processor, on a condition that there is no configuration instance entry in the database, further configured to store a new configuration instance entry in the database based on the received CCC value;
- and
- the processor is further configured to determine whether the received CCC value matches a CCC value stored in the database, and on a condition that the received CCC value does not match any CCC value stored in the database, update the database based on the received CCC value.
