A.3 Access to SCFs in another network

22.1273GPPRelease 9Service requirement for the Open Services Access (OSA)Stage 1TS

Service Scenario Description

Two operators, a wireline operator A and a wireless operator B, belonging to the same telecommunication group, have adopted OSA solutions. Each of them introduced in its service platform an OSA Gateway, to provide to application layers (also in 3rd party domains) a relevant subset of capabilities implemented in its network.

Let assume that a corporate is implementing a rich VPN-like service by exploiting the features provided by the wireline operator (i.e., the corporate subscribed a subset of the SCFs provided by wireline operator). If such a corporate wants to enhance its application with the capability to handle with SMSs sent/received by the members of its VPN (e.g., its employees) and the wireline operator does not provide any appropriate network capabilities, according to the current specifications, the corporate must subscribe the needed SCF (e.g., a User Interaction implemented through SMSs) provided by another operator (e.g., the wireless operator B). But in this case, the corporate must deal with two subscriptions, its VPN application must cope with two OSA Gateways; in addition, the corporate could select a different wireless operator, not belonging to the same group of the operator A.

Figure 4: Operator A and Operator B relationship

Such a situation could be dealt by enhancing the OSA specifications in order to allow the OSA Gateways belonging to A and B to be “federated”, in order to allow the subscribers to the OSA Gateway in A to access also, in a controlled way, the service capabilities provided by the OSA Gateway in B. This means that the applications do not have to deal with the complexity of handling two OSA Gateways, the application service provider does not have to open a new customer relationship with another operator, and the operator A has not to introduce additional service capabilities in its infrastructure.
