Abstract: A slave device accesses an external network through a master device via a short-range wireless communication channel between the master device and the slave device. The slave device receives a notification message from the master device, wherein the notification message includes information about a intermediate network used by the master device to connect to the external network. And the slave device controls network traffic between the slave device and the external network according to a type of the intermediate network. When a master device uses a network of a cellular network type, use of network traffic in an application on a slave device can be restricted, thereby saving traffic.

Abstract: In a wireless network discovery operation, before a WiFi station sends a network probe request in a WiFi network to request for network information it needs to connect to an access point, it first listens to communications on a current channel of the WiFi network for a preset period of time. When the WiFi station receives on the current channel a network probe request message sent by another WiFi station, it further delays sending the first network probe request by a second time period, in anticipation of some signals from the access point. If during the second time period a network discovery message from the access point, such as a probe response or a beacon message, is detected and that message contains the network information needed, the WiFi station cancels the sending of its probe request. Otherwise, the WiFi station sends its probe request after the second time period expires.
