A technique is provided for a mobile terminal to initiate a join operation with timing information received from a previous beacon and WLAN chipset's internal reference timestamp so that the WLAN chipset can synchronize itself with an access point network without needing to wait for a subsequent beacon as defined in the 802.11 standard specs. The WLAN modem needs to get necessary timestamp (a time synchronization function (TSF)-correction)) information for performing the join-operation. The mobile terminal has its own TSF-counter and to join with the access point the TSF-counter needs to be synchronized with the access points TSF-counter. This update is performed in the WLAN modem using a communication that has been previously received from the access point (latest beacon, probe, etc.). With this information available, there is no need for the WLAN modem to wait for the next beacon to perform the join operation. |
