Embodiment Construction

[0047] The methods described below help reduce response times for requests for telematics services. Typically, requests for telematics services such as routing directions involve two types of calls - circuit switched and packet switched. Each type of call may be initiated and terminated in the course of providing route planning directions to the vehicle. The initiation and termination of these calls takes a certain length of time to perform, which always delays the final delivery of the service for the requester. In addition, circuit switched calls can be used in a voice mode for performing voice transmissions and a data mode for performing data transmissions. Also, the process of responding to a service request may involve switching between data and voice modes.

[0048]All of these actions take time that delays the response, regardless of whether the request to respond to the telematics service involves a different type of call or a different mode. Typical requests for te...

Abstract

The invention relates to a method of speeding call flow. More specifically, a system and a method for communicating between a vehicle and a central facility includes initiating at a vehicle a request for turn-by-turn directions; establishing a packet-switched call between the vehicle and a central facility using a wireless carrier system and a mobile dialed number (MDN) associated with the vehicle; receiving determined route information at the vehicle from the central facility via the packet-switched call; offering a vehicle occupant a service option that uses a circuit-switched call; and if the vehicle occupant accepts the service option, directing the wireless carrier system to establish the circuit-switched call using the MDN while maintaining the packet-switched call in a dormant state.

Description

technical field [0001] The present invention relates generally to vehicles, and more particularly to communication between the vehicle and a central facility. Background technique [0002] Modern vehicles are capable of providing a large number of services to the vehicle occupants. Vehicle occupants may use the vehicle telematics device to communicate voice and data with external parties, such as a central facility or third-party callers. As one example, vehicle occupants may request and receive assistance and / or services from a central facility, such as a call center equipped with on-call advisors. For example, a vehicle occupant may request navigation directions from one geographic location to another from a central facility; such requests are often referred to as requests for routing directions. The process of enforcing this request involves the initiation and termination of multiple data and voice calls. Sometimes the number of calls and / or the amount of time spent in...
