Abstract
In a first embodiment, when an Activate PDP Context Request message is forwarded to a Service GPRS Support Node (SGSN), the SGSN creates a Create PDP Context Request message and forwards it to a Gateway GPRS Support Node (GGSN). In response to the Create PDP Context Request forwarded by the SGSN, the GGSN creates a Create PDP Context Response message. When a PDP context is created by the GGSN, the GGSN associates a Globally Unique Charging Identification (GCI) with the PDP context. Then, the Create PDP Context Response including the GCI is forwarded to the SGSN. The GCI is sent from the SGSN to the UE and from the UE to the CSCF. In a second embodiment, the GCI is sent from the SGSN or the GGSN directly to the Call State Control Function (CSCF). Sending the GCI can be performed either autonomously or based on a request from the CSCF. In either embodiment, the CSCF can send the GCI to a second network which performs processing, such as billing, from data collected from call detail records associated with the GCI.
