ARCHITECTURE FOR DELIVERING DATA TO MOBILE TELEMATICS UNITS
First Claim
1. A method of transmitting data from a first telecommunications unit to a second telecommunications unit, wherein at least the second telecommunications unit is a mobile unit, the method comprising:
- identifying a body of data to be provided to the second unit, the body of data having associated therewith a data length value and one or more security constraints;
determining whether a PPP session is open between the first telecommunications unit and the second telecommunications unit; and
transmitting the body of data from the first telecommunications unit to the second telecommunications unit via IP over the existing PPP session if it is determined that a PPP session is open between the first telecommunications unit and the second telecommunications unit, and otherwise determining, based on at least one of the data length value and security constraints, whether to transmit the body of data via PPP or instead via an SMS message.

Abstract
An improved mobile connectivity system and method allow for data transfers, such as related to service delivery, to and from mobile wireless units in an economical and secure manner. The system utilizes existing IP connectivity when available and otherwise determines an appropriate data exchange mechanism based on the length and security requirements of the intended exchange. Data exchange mechanisms include SMS, IP and other suitable protocols, and wireless carriers include cellular and non-cellular wireless carriers. In an example, each subscriber unit periodically, or when triggered, sends its location to a call center to allow the delivery of location-based services.

13. A method of receiving data at a mobile telecommunications unit from a substantially stationary telecommunications unit, the method comprising:
-
receiving a body of data at the mobile unit from the substantially stationary telecommunications unit via an SMS message; subsequent to the step of receiving the body of data at the mobile unit, receiving at the mobile unit from the substantially stationary unit a request to initiate a PPP session from the mobile unit to the substantially stationary unit; and at the mobile unit, in response to the received request to initiate a PPP session, initiating a PPP session from the mobile unit to the substantially stationary unit. - View Dependent Claims (14, 15, 16, 17)

18. A method of receiving data at a mobile telecommunications unit from a substantially stationary telecommunications unit, the method comprising:
-
receiving at the mobile unit from the substantially stationary unit a request to initiate a PPP session from the mobile unit to the substantially stationary unit; at the mobile unit, in response to the received request to initiate a PPP session, initiating a PPP session from the mobile unit to the substantially stationary unit; and receiving a body of data at the mobile unit from the substantially stationary telecommunications unit via the PPP session. - View Dependent Claims (19, 20)
