Abstract
The present invention relates to a method and an apparatus for searching for an access point of a terminal in a wireless communication system, and the method for searching for an access point of a terminal in a wireless communication system according to the present invention comprises the steps of: transmitting a probe request frame including an identifier for searching for a specific access point; receiving a probe response frame transmitted from the access point related to the identifier; and connecting to the access point having transmitted the probe response frame.
Claims18
A method by a terminal to scan an access point (AP) in a wireless communication system comprising:
- setting, by the terminal via a user interface in the terminal, a policy set for priority access to an AP related to an operator;
- transmitting a probe request frame containing an identifier related to the operator for searching for the AP related to the operator, the identifier being determined based on the policy set for the priority access;
- receiving, from the AP related to the identifier, a probe response frame containing the identifier related to the operator;
- and
- attempting to access the AP that transmitted the probe response frame.
A method by an access point (AP) to respond to the AP scan in a wireless communication system comprising:
- receiving, from a terminal, a probe request frame containing an identifier related to an operator for searching for an AP related to the operator, the identifier being determined based on a policy set for priority access;
- identifying an identifier related to the operator contained in the probe request frame;
- determining whether the identified identifier corresponds to an identifier related to the AP;
- and
- when the identified identifier corresponds to the identifier related to the AP, transmitting, to the terminal, a probe response frame containing the identifier related to the AP in response to the probe request frame,
- wherein the policy set for priority access to the AP related to the operator is set by the terminal via a user interface in the terminal.
A terminal configured to scan access points (APs) in a wireless communication system comprising:
- a wireless local area network (WLAN) communication interface for transmitting and receiving a signal;
- and
- a WLAN access management for setting, via an interface in the terminal, a policy set for priority access to an AP related to an operator, transmitting a probe request frame containing an identifier related to the operator for searching for the AP related to the operator, the identifier being determined based on the policy set for the priority access, receiving, from the AP related to the identifier, a probe response frame containing the identifier related to the operator, and performing a control operation to attempt to access the AP that transmitted the probe response frame.
An access point (AP) configured to respond to the AP scan in a wireless communication system comprising:
- a wireless local area network (WLAN) communication interface for receiving and a transmitting a signal;
- and
- a controller for receiving, from a terminal, a probe request frame containing an identifier related to an operator for searching for an AP related to the operator, the identifier being determined based on a policy set for priority access, identifying, when receiving the probe request frame from the terminal, an identifier related to the operator AP contained in the probe request frame, determining whether the identified identifier corresponds to an identifier related to the AP, and transmitting, when the identified identifier corresponds to the identifier related to the AP, a probe response frame containing the identifier related to the AP in response to the probe request frame to the terminal,
- wherein the policy set for priority access to the AP related to the operator is set by the terminal via an interface in the terminal.
