    Abstract: Various multiple methods of data transport, and combinations thereof, may be used to initialize or update conditional access information on various devices. In an integrated device having both a broadcast receiver, such as an SDARS receiver, and a two-way communications transceiver, such as an LTE, 3G, 4G or 5G modem, or the like, conditional access information for the broadcast receiver may be sent to the transceiver, and then passed to the broadcast receiver, or vice versa. Additionally, for example, the broadcast receiver may be sent, over the broadcast communications channel, a “wake-up” message for the two-way transceiver, which message may then be passed to the two-way transceiver, so as to make it ready to receive conditional access information over the two-way communications channel, or vice versa. Moreover, because of the presence of a two-way communications path, various acknowledgements of conditional access status updates received and processed by the broadcast receiver may be sent—thus realizing a significant improvement over the current practice of sending multiple periodic messages over the broadcast channel, to insure (but never have confirmation of) receipt.

    Abstract: In exemplary embodiments of the present invention, a V2V unit in a vehicle (OBE) can, for example, store a plurality of years of encrypted certificates. The certificates can, for example, be programmed at an OBE factory using a secure server, and access to all certificates can be locked until an unlock key is computed for a given window (certificate validity period). An in-vehicle satellite receiver can then receive, over, for example, a dedicated satellite control channel, unlock codes for a current time window and a next time window, and provide them to the V2V device. Using those unlock codes, the V2V device (OBE) can compute an unlock key from an unlock code provided by the satellite receiver. In this manner an in-vehicle device may be directly messaged, but only to unlock one or more certificates at a controlled time. Without the received lock codes, the stored certificates are not useable.

    Abstract: A vehicle messaging method (600) and system (100) can include any number of data sources (101-103), an interface (104) that formats messages and addresses from the data sources, and a corresponding number of messaging servers (111-113) that receive targeted messages intended for a predetermined subset of subscribers associated with a vehicle identification number (VIN). Each messaging server can include a corresponding controller (121-123) programmed to assign (604) targeted messages to a predetermined channel and encode (606) the addresses of the targeted messages to the predetermined subset of subscribers using a VIN or portion thereof. The controller can be further programmed to transfer (608) the targeted messages and addresses to a satellite uplink (107) and satellite (110) via a messaging uplink interface (106) for retransmission and reception by a plurality of selective call receivers 109 addressable individually using a predetermined VIN or portion thereof.

    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.

    Abstract translation: 提供车载远程信息处理控制单元(“TCU”)的蜂窝服务的卫星提供。 因此,促进了真正的运营商独立TCU。 TCU可以设置有蜂窝调制解调器和两个或更多个SIM卡,每个SIM卡与已批准调制解调器及其SIM卡的蜂窝载波相关联。 也可以向TCU提供与卫星的连接,例如经由可以接收和处理SDARS音频和数据信号的SDARS天线和处理模块。 当用户期望从蜂窝载波之一改变为另一个时,现在已经在远程信息处理系统中的新载波的SIM的供应数据可以是(i)通过卫星发送,(ii)在卫星天线处接收,以及 (iii)传送到远程信息处理器。 远程信息处理器又可以(iv)将供应数据传送到小区调制解调器,然后可以(v)使用供应数据来编程适当的SIM,从而允许新载波的网络上的蜂窝通信。 本发明的功能有助于在跨越边界时容易地切换运营商,或者当新车辆被导入到给定国家时,并且在一个认可运营商上可用的蜂窝服务容易地由用户选择并打开。 TCU还可以包括被配置为通过Wi-Fi网络接收供应指令或数据的Wi-Fi模块。
