Title: AP RESPONSE METHOD, AP DISCOVERY METHOD, AP AND TERMINAL
Abstract:
Disclosed are an AP response method, AP discovery method, AP and terminal, the AP response method comprising: an AP receives a probe request message transmitted by a terminal, the probe request message containing network roaming indication information, and the network roaming indication information containing the home network indication information of the terminal; if the network indicated by the home network indication information of the terminal has signed a roaming protocol with the network that the AP is in, the AP allows to reply a probe response message to the terminal, enabling the terminal to discover the AP. The present invention does not require all the APs in the network to transmit a probe response message to the terminal, but only requires the AP in the network having signed the same network roaming protocol with the network that the terminal is in to respond to the probe response message, thus saving network resources; furthermore the terminal avoids processing the probe response message replied by the AP not having signed the network roaming protocol, thus reducing AP discovery time of the terminal, and correspondingly improving the network access speed of the terminal.
