METHOD AND SYSTEM FOR GSM BILLING DURING WLAN ROAMING.

摘要

The invention relates to a method and system for recording and billing services during the roaming of a mobile IP node (20) in heterogeneous WLANs. According to the invention, first call detail records are transmitted from an access server (23/1001) to a billing module (1003) and second call detail records are transmitted from the access server to a proxy module (1002). The service requested from a provider (1008) of a fixed network (1007) is billed (1016) by means of a clearing module (1004) and/or the TAP files (1017) are transmitted to a GSM (1005) service provider (1006) for billing.
