High-quality and reliable software
BAF is an extension of the GateHouse BGAN Protocol Stack (BPS). BAF is high-quality and extremely reliable software. It can easily be extended according to customer requirements, minimizing the risk, cost, and time of delivery for a BGAN application layer. BAF utilizes the ETSI defined API in BPS. The ETSI interface is a generic interface for UMTS protocol stacks and relatively complex. Therefore, BAF is designed to encapsulate the complexity of the usage of the ETSI API. BAF architecture is shown in the figure above. It illustrates how BAF encapsulates the complex ETSI 3GPP interface consisting of several Service Access Points (SAP’s) (RABM, SM, PLMN, GMM, MM, AP, SMS, CC, SS and VC/HL).
The key components of the BGAN Application Framework are:
- Standard AT Handler also supporting BGAN specific commands
- Handlers for Network Access Control, Packet Switched and Circuit Switched calls, including SMS
The AT handler also supports the Inmarsat BGAN terminal application: LaunchPad.
