摘要： The embodiments herein relate to a method in a RAN node (305) for determining which operator that should serve a device (301 ) when it has been handed over from a source network to a target shared network (300). When the device (301 ) has been handed over to the target shared network (300), the RAN node (305) transmits, to a non-registered CN node (312) in a non-registered domain (300nr), a request for an identity of the device (301 ). The RAN node (305) transmits a request, to CN nodes (310) in a registered domain (300r), for a serving operator which has registered the device (301 ). The RAN node (305) receives information indicating the serving operator. The RAN node (305) determines that the same serving operator which served the identified device in the registered domain (300r) should also serve the device (301 ) in the non-registered domain (300nr).

摘要： A satellite communications system includes a satellite that is configured to wirelessly communicate with radioterminals in a satellite coverage area over a satellite frequency band, and an ancillary terrestrial component that is configured to wirelessly communicate with radioterminals in the satellite coverage area over at least some of the satellite frequency band, to thereby terrestrially reuse at least some of the satellite frequency band. Wireless communications with a radioterminal are handed over from the ancillary terrestrial component to the satellite if the radioterminal transmit power exceeds a threshold, and a received satellite signal quality exceeds a threshold, even though the radioterminal is able to wirelessly communicate with the ancillary terrestrial component. Downlink wireless radiation that is received at the radioterminal from a satellite may be monitored to determine potential interference created by the uplink radiation of the radioterminal due to the terrestrial reuse of at least some of the satellite frequency band.

摘要： A user key validation during a handoff verifies the subscriber using the wireless communication system and prevents fraudulent use of the system. A wireless communication system (10) has a number of satellites (20, 22, 24) with which a subscriber unit (12) establishes a communication link. However, as the quality of the transmitted signal between an active satellite (22) and the subscriber unit (12) degrades, a handoff of the communication link with the subscriber unit (12) will occur if the subscriber (12) meets the authentication requirements of the system (10). The active satellite (22) generates user keys and transmits the user keys to the active subscriber units (12). A request of a handoff is made from the individual subscriber unit (ISU) (12) to the losing SV (22). The losing SV (22) communicates with the gaining SV (20) to establish a handoff. The losing SV (22) sends the user key of the ISU (12) to the gaining SV (20). The gaining SV (20) authenticates the ISU (12) by comparing the ISU user key to a user key stored in the losing SV (22). The gaining SV (20) becomes the active satellite, and generates and transmits the user key to the ISU. Notification of the authentication is sent to an earth terminal controller (30). The earth terminal controller (30) provides the losing SV (22) with notification that the handoff is complete. The authentication prevents further fraud if the subscriber fraudulently obtained access to the system during the original call set up.

摘要： The invention concerns a telecommunication method based on moving satellites (S1, S2, S3 and S4) whereby the earth is divided into zones (20i) inside which the communications of the terminals of said zone with the network are relayed by a managing station (22) and a communication terminal (241, 242) and the managing station is provided via a satellite, another satellite taking over the communication when the first satellite is no longer being used. To command the transfer of communications from one satellite to another, predetermined times are selected during which at least two satellites are simultaneously visible from the zone, or from part of the zone. The command for communication transfers is for example collectively carried out for a plurality of terminals.

摘要： Approaches for efficient, dynamic and continuous handover processes, which encompass selection of an optimal path (consisting of a satellite, a satellite beam and carrier frequency set) over which a mobile user terminal (UT) communicates with the radio access network in a mobile satellite communications system, are provided. A set of path factors are determined regarding each of a plurality of communications paths for the UT. A path selection metric (PSM) for each communications path is determined, wherein the PSM for each communications path is determined via a weighted calculation based on the respective set of path factors for the communications path. A decision is made as to whether to perform a handover of the UT from a first of the communications paths to a second of the communications paths, wherein the determination is based on an evaluation performed based at least in part on the PSM.

摘要： 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.
