ABSTRACT:
Techniques are provided herein to improve the manageability of handover performance of multi-mode wireless client devices when roaming between a wireless local area network (WLAN) and at least one other network. Signals are received at a plurality of WLAN access points from multi-mode wireless client devices. The WLAN access points generate handover data associated with handover events of wireless Voice-Over Internet Protocol (VoIP) communication sessions for the multi-mode wireless client devices between the wireless local area network and at least one other network. The WLAN access points also generate link quality data representing status and quality of a wireless link with multi-mode wireless client devices during a VoIP communication session. A controller that is provided that is configured to receive the handover data and link quality data for multi-mode wireless client devices from the plurality of access points. The controller aggregates the handover data and link quality data for a VoIP communication session for a multi-mode wireless client device into a mobility detail record and stores the mobility detail record together with an identifier of an associated call detail record.
