WLAN-CDR Charging Information Addition
The “List of Traffic Volumes” attribute of the WLAN-CDR consists of a set of containers, which are added when
specific trigger conditions are met, and identify the volume count per PDP context, separated for uplink and downlink
traffic, on encountering that trigger condition.
specific trigger conditions are met, and identify the volume count per PDP context, separated for uplink and downlink
traffic, on encountering that trigger condition.
The following table identifies which conditions are supported to trigger WLAN-CDR charging information addition.
Volume container identifies the uplink/downlink volume since the closure of the last container. The “Serving Node
Address” attribute of the SGW-CDR consists of a list of serving node (for example, MME) addresses. A new serving
node address is added to the list when MME changes.
