Abstract
Abstract The SS7 network signalling address of a serving exchange for a cellular system is used to construct a unique network call identifier for a mobile call. This unique network call identifier is communicated across the networks to allow multiple serving exchanges associated with a roaming subscriber to produce call data records to a separate network or a node and have it correlate the billing records with a single call. Every mobile call within the cellular networks will have a unique call identifier, and this call identifier is communicated from the anchor exchange to the serving exchange during an interexchange handoff process to identify the transferring call across the network.
