Abstract

At present, still problematical is the efficient charging, by a mobile network operator, of resources used in a mobile terminal even when a connection between the terminal and the network is temporarily not available. The Open Mobile Alliance (OMA) Mobile-Commerce and Charging (MCC) working group is defining network layer independent charging mechanisms, which are then taken over by e.g. 3GPP and 3GPP2 to develop their particular solutions that allow fulfilling the OMA requirements. Already proposed is a mechanism that allows the "Terminal Application Initiated Charging" use case to be covered by general OMA charging architecture. This mechanism contains the forwarding of the charging information collected on the terminal to the network and then feed it in the existing operator charging mechanisms using a charging proxy on the network side. This contribution assumes that data link between the mobile terminal and the charging proxy in the network is always available. As this is not always the case, the present idea proposes a charging proxy emulator running in the mobile device. The goal is that a consistent user experience can be maintained by differing the data exchange until a suitable data link can be set up.

Charging proxy in a mobile terminal for the purpose of differing the forwarding messages

Idea: Enric Mitjana, DE-Munich

At present, still problematical is the efficient charging, by a mobile network operator, of resources used in a mobile terminal even when a connection between the terminal and the network is temporarily not available. The Open Mobile Alliance (OMA) Mobile-Commerce and Charging (MCC) working group is defining network layer independent charging mechanisms, which are then taken over by e.g. 3GPP and 3GPP2 to develop their particular solutions that allow fulfilling the OMA requirements.

Already proposed is a mechanism that allows the "Terminal Application Initiated Charging" use case to be covered by general OMA charging architecture. This mechanism contains the forwarding of the charging information collected on the terminal to the network and then feed it in the existing operator charging mechanisms using a charging proxy on the network side. This contribution assumes that data link between the mobile terminal and the charging proxy in the network is always available. As this is not always the case, the present idea proposes a charging proxy emulator running in the mobile device. The goal is that a consistent user experience can be maintained by differing the data exchange until a suitable data link can be set up.

Until now, mobile communication services have been offered and controlled by Public Land Mobile Network (PLMN) operators. As services beyond voice start to emerge (e.g. ring tones or games download), new players are becoming part of the value chain. However, the operators still regulate the access to these 3rd party services and are responsible for the charging and billing of these services. In most cases, the services are integrated in the operator's service offering in such a way that the user does not know that he is using 3rd party services. For these services, the charging is done on appropriate network entities, solely within the core PLMN. Thus, at present and for some time to come, all charging and resulting payment settlements are done by the PLMN operators. However, new applications and their resulting usage patterns consume resources only on the terminal (e.g. play back of an MP3-coded song or play game locally on the device), which implies that the core network is not aware of the service usage as no mechanism has been devised yet for reporting this resource usage. Thus, the so called "event charging", with the special case that the charging events are generated by applications running on the terminal device, is gaining relevance. To settle payments in such scenarios, premium-SMS methods have been suggested where the terminal sends an especial SMS message in order to be charged for the local resource use.

Thus, solutions that enable network operators to offer simple settlement mechanisms to their subscribers supporting terminal initiated event charging are important for the further developme...
