Patent ID: 8799445

Claim:
A WLAN apparatus, comprising: a processor in a WLAN host device; and a memory in the WLAN host device including a computer program code and a plurality of applications seeking scan results, the memory and the computer program code configured to, with the processor, cause the apparatus at least to receive a plurality of requests from more than one application to provide scan information, and receive a plurality of maximum latency values indicating maximum delay times by which a scan operation may be delayed, perform the scan operation, wherein in the scan operation, a network detection is performed, and wherein the scan operation is performed independently from receiving the plurality of requests from more than one application to provide the scan information such that the timing of performing the scan operation is independent from the timing of the requests and the scan operation is not performed every time one of the requests from more than one application is received, and wherein an interval for performing the scan operation is based on a minimum value of the maximum latency values; allow the multiple applications to register for delayed scan results as the scan requests for scan information, send to the multiple applications the scan results based on a parameter included in the scan request, indicating the maximum latency value to execute the scan operation, and the memory and the computer program code are further configured to, with the processor, cause the WLAN apparatus at least to extract the maximum latency value from the request to provide scan information to each of the multiple applications simultaneously based on the parameter indicated in each individual scan request per the multiple applications.
