Title:
SATELLITE PROVISIONING OF CELL SERVICE
Document Type and Number:
WIPO Patent Application WO/2015/134644
Kind Code:
A9
Abstract:
Satellite provisioning of cell service for an in-vehicle telematics control unit ("TCU") is presented. Thus, a truly carrier independent TCU is facilitated. A TCU may be provided with a cellular modem and two or more SIM cards, each associated with a cellular carrier that has approved the modem and their SIM card. The TCU may also be provided with connectivity to a satellite, such as, for example, via an SDARS antenna and processing module, that can receive and process SDARS audio and data signals. When a user desires to change from one of the cellular carriers to another, provisioning data for the new carrier's SIM, now already in the telematics system, may be (i) sent over the satellite, (ii) received at the satellite antenna, and (iii) passed to a telematics processor. The telematics processor, in turn, may (iv) deliver the provisioning data to the cell modem, which may then (v) program the appropriate SIM with the provisioning data, thus allowing cellular communications on the new carrier's network. The inventive functionality facilitates easily switching carriers as one crosses a border, or when a new vehicle is imported to a given country, and cellular service then or there available on one of the approved carriers is easily chosen by a user and turned on. The TCU may also include a Wi-Fi module, configured to receive provisioning instructions or data over a Wi-Fi network.
