Windows Embedded Automotive 7 Deep Dive: Phone Core and Media Core 53
Figure 14: Connection Manager
The Connection Manager supports the following CSPs:
• RAS CSP provides General Packet Radio Services (GPRS) and dial-up connection support.
When used with a Bluetooth phone, RAS CSP relies on the setup menu HMI for
configuration of the dial strings.
• Voice CSP helps with the coordination of circuit switched data (CSD) and voice calls on
an embedded phone. The HFP service calls into the voice CSP for operations that are
related to voice calls on an embedded phone.
• Proxy CSP allows the insertion of proxy links between defined network destinations. It
could be used to create a “virtual” destination that is used by applications logically
linked to a “real” destination, which can then be reprovisioned without the need to
change the applications.
• Bluetooth Voice CSP coordinates between data and voice calls on a Bluetooth phone. It
keeps the Connection Manager aware of whether the Bluetooth phone is present or
not. When a Bluetooth voice call occurs, Bluetooth Voice CSP creates a pseudo-
Bluetooth voice connection so that attempts to create a CSD connection fail. Existing
CSD connections are then disconnected, and GPRS connections are suspended.
Data Connectivity
Windows Embedded Automotive 7 supports applications that use a paired Bluetooth phone for
data access. The Connection Manager supports the ability to share a mobile phone among
various applications for different access modes through intelligent, priority-based management
of the phone’s resources.
Automotive 7 provides the following data connectivity options:
• Bluetooth DUN
• Bluetooth Gateway Services (BGS)
• Virtual serial ports
• PAN
Bluetooth Dial-up Networking
Windows Embedded Automotive 7 supports the Bluetooth DUN Profile 1.1. This profile provides
the ability to access the internet and other dial-up services through a Bluetooth-enabled phone.
