摘要
The described invention provides a method and system for allowing subscribers of a telematics service provider (TSP) to make hands-free phone calls within their vehicles through a telematics unit over a network or hardware-based pre-pay system, wherein the telematics unit or a wireless network provider associated with the TSP controls the ingoing and outgoing hands-free calling (HFC) processes. The wireless network provider, through its system at a remote call center or through the telematics unit, may determine whether the subscriber has subscribed to the TSP's HFC service, whether the subscriber has a sufficient remaining balance to initiate, receive or continue a call, and whether a user of the telematics unit is “roaming.” When a user attempts to make or receive a call through the telematics unit, the wireless network provider or the telematics unit may handle the incoming or outgoing call processing, and may further provide subscriber account balance notifications to the user.
