8 Automatic Roaming Agreements
22.1153GPPCharging and billingRelease 17Service aspectsTS
Support for the requirements in this section is not required in Release 99. However the Release 99 standards should not prevent the future implementation of this requirement in a backward compatible manner (e.g. a roaming broker enabled Home Environment should inter-operate with a R99 Serving Network).
It is a requirement that users shall be able to obtain service and use chargeable services with networks with whom neither they nor their home environment have any direct commercial agreement. This shall be enabled by interworking via trusted third parties. Each Home Environment shall interwork with one or more serving network operators, with whom they would negotiate a commercial roaming agreement and test the interworking. Any user wishing to use the services of a particular serving network would register with that serving network, that would either directly or indirectly interwork with the home environment. Fraud and cost control mechanisms shall be used to ensure that charges incurred for 3GPP services do not exceed the credit limits set. This can be applied for the user and the other roles involved in commercial dealings. In practice, any serving network shall be capable of operating as a roaming broker.
Figure 1: Registration and Roaming Process
8.1 Routing the Registration Request
The same mechanisms used for routing calls and resolving addresses shall be used to route the subscription identity back to its Home Environment. The standard shall support a routing identification mechanism to allow a serving network, which does not maintain its own list of all known HE, to determine the appropriate route to reach a given HE. A number of alternative routes may be possible, and ideally the system should be capable of determining the lowest cost to the end user.
Typically, smaller networks will only have a limited number of external connections to other networks or clearing houses, but may not know which one to use for an unknown (new) HE. In this case, the serving network may make a number of inquiries for each route to determine the lowest cost route to handle the call.
8.2 Settlement of charges
Settlement of charges incurred by a user shall be on a wholesale basis between the different parties involved in the registration link. By authorising a user to register, or a roaming broker to pass that on, each party is in turn authorising charges up to a maximum credit limit with the adjacent party. Any charges levied can then be paid to the adjacent party on a wholesale basis at the end of a mutually agreed accounting period. Funds are thus passed between each party for the services supplied by the network operator in a serial fashion.
