Performance management of mobile intelligent roaming using mobility detail records

A system comprising:

• a plurality of wireless local area network access points that are part of a wireless network that serves one or more multi-mode wireless client devices that are capable of communicating in the wireless local area network and in at least one other network, wherein the access points are configured to receive signals from the multi-mode wireless client devices and to generate data related to handover events of a wireless Voice-Over Internet Protocol (VoIP) communication sessions for multi-mode wireless client devices between the wireless local area network at the at least one other network and to generate link quality data representing status and quality of a wireless link with multi-mode wireless client devices during a VoIP communication session;
• and
• a controller that is configured to communicate and receive data from the plurality of access points, wherein the controller is configured to receive the handover data and link quality data for multi-mode wireless client devices from the plurality of access points, aggregate the handover data and link quality data for a VoIP communication session for a multi-mode wireless client device into a mobility detail record, associate each mobility detail record with a call detail record that describes end-to-end performance metrics associated with a VoIP communication session;
• store the mobility detail record together with an identifier of its associated call detail record.

A non-transitory tangible computer readable medium comprising program code for execution by a computer and when executed operable to:

• receive from a plurality of wireless local area network access points handover data associated with handover events of wireless Voice-Over Internet Protocol (VoIP) communication sessions for multi-mode wireless client devices between the wireless local area network and at least one other network;
• receive from the plurality of wireless local area network access points link quality data representing status and quality of a wireless link with multi-mode wireless client devices during a VoIP communication session;
• aggregate the handover data and link quality data for a VoIP communication session for a multi-mode wireless client device into a mobility detail record;
• associate each mobility detail record with a call detail record that describes end-to-end performance metrics associated with a VoIP communication session for each multi-mode wireless client device;
• and
• store the mobility detail record together with an identifier of its associated call detail record.

A method comprising:

• at a controller, receiving from a plurality of wireless local area network access points handover data associated with handover events of wireless Voice-Over Internet Protocol (VoIP) communication sessions for multi-mode wireless client devices between the wireless local area network and at least one other network;
• at the controller, receiving from the plurality of wireless local area network access points link quality data representing status and quality of a wireless link with multi-mode wireless client devices during a VoIP communication session;
• at the controller, aggregating the handover data and link quality data for a VoIP communication session for a multi-mode wireless client device into a mobility detail record;
• at the controller, associating each mobility detail record with a call detail record that describes end-to-end performance metrics associated with a VoIP communication session for each multi-mode wireless client device;
• and
• at the controller, storing the mobility detail record together with an identifier of its associated call detail record.
