| 20080228398 | Timed-based ephemeris identity in assistance data and assistance data request messages - A module (software or ASIC) for use in a serving mobile Location Centre (SMLC) or a mobile station having a GPS receiver (or an A-GPS receiver) for determining an ITOW for a CNAV-1 signal. Also provided is a module for a mobile with GPS (or A-GPS receiver) so that the mobile can use the ITOW (either the ITOW provided with the CNAV-2, or that calculated for the CNAV-1) to uniquely identify ephemeris information in a request for assistance message. Also provided is a module for a SMLC by which the SMLC can use the IOD fields in the assistance data messages in a way that uniquely identifies the associated ephemeris information. | 09-18-2008 |
| 20080234980 | Assistance data provision - For supporting the provision of a continuous stream of assistance data for a satellite signal based positioning, a sequence of interlinked messages comprising assistance data is generated. The messages are provided for transmission to a wireless communication terminal. The wireless communication terminal receives the sequence of interlinked messages and provides the assistance data in the received messages for use in positioning computations. | 09-25-2008 |
| 20090146882 | METHOD AND SYSTEM OF GENERIC POSITION SIGNALLING FOR CELLULAR NETWORKS - Systems and methods provide location support for assisted navigation systems, for example, with respect to assistance data specifications and protocols in systems without impacting a cellular system-specific control plane protocol. Location support for cellular systems can be introduced into only the user plane of a particular cellular system by including/introducing certain relevant information to existing parameters within the user plane. Additionally, support for new cellular systems is introduced into the user plane protocol by defining its “identification” to the protocol. | 06-11-2009 |
| 20090325611 | Event-Based Assistance Data Delivery - A method and system which may determine when to deliver assistance data to a requesting user device. In one example, the user device may request updates of assistance data related to one or more data type from an assistance server. Additionally, the user device may include one or more parameters for the delivery of updates of assistance data. The assistance server may provide updated assistance data based on an event and in compliance with the one or more parameters. | 12-31-2009 |
| 20100156710 | SYNCHRONIZATION INDICATION IN NETWORKS - Systems and methods provide a network's synchronization status to a terminal when the terminal receives a transmission from the network. This network synchronization status can be indicated in accordance with various methods including, but not limited to the following: with a status flag in a network message; in a network capability indication; in a network's positioning capability indication; cell/network time relation information; in a time relation information of different Radio Access Technologies; and implicitly with another parameter and/or by a request for a certain measurement. When the network's synchronization status is determined, accurate time information/time assistance data can be maintained at the terminal. | 06-24-2010 |
| 20100283677 | Method, system, user equipment, network element and software product for generic broadcasted positioning assistance data - A method, system, user equipment and network element are for creating positioning assistance data messages in a generic format that assist mobile stations to determine their positions based upon signals from various types of global navigation satellite system. Scheduling information is broadcasted from a terrestrial base station, describing which of the positioning assistance data messages contain positioning assistance data for which of the types of global navigation satellite system. That positioning assistance data is broadcasted in messages from a terrestrial base station, according to the scheduling information. | 11-11-2010 |
| 20110032146 | Providing Positioning Assistance Data - For supporting the use of positioning assistance data, a positioning assistance server collects positioning assistance data from at least one mobile device and Provides the collected positioning assistance data for distribution to at least one other device. | 02-10-2011 |
| 20110032859 | PROVIDING POSITIONING ASSISTANCE DATA - For supporting the use of positioning assistance data, the positioning assistance data is broadcast in a plurality of different logical sub-channels. The positioning assistance data is distributed to the plurality of different logical sub-channels depending on its content. | 02-10-2011 |
| 20110046874 | ASSISTANCE DATA SPECIFICATIONS AND PROTOCOLS FOR NAVIGATION SYSTEMS - Assistance data specifications and protocols for navigation systems in cellular networks and/or other networks. These specifications and protocols do not impact system-specific control plane protocols. According to various embodiments, a bearer and satellite system-independent meta structure may be protected for periodic and/or continuous transfer, e.g., streaming, of assistance data in a network. As a result, the need for the arrangement of multiple individual sub sessions may be reduced or eliminated in various embodiments. | 02-24-2011 |
| 20110071926 | METHOD AND SYSTEM FOR OBTAINING SERVICES - A method for obtaining a service by a first terminal related to a network entity, the method comprising receiving information indicative of capabilities related to the network entity; and selecting one or more of the capabilities. | 03-24-2011 |
| 20110109505 | GNSS SATELLITE FREQUENCY IS IN GNSS ASSISTANCE DATA STANDARDS - Systems and methods are provided to allow for the use of existing satellite identification parameters generically, so as to allow for Global Navigation Satellite System (GLONASS) identification. In addition, an optional or conditional parameter is linked to the satellite identification parameter for a frequency identification, where frequency identification is indicative of a Frequency Division Multiple Access (FDMA) frequency value. Such a frequency identification parameter is optional as it is needed only for current GLONASS and/or near-future GLONASS (e.g., GLONASS-M) satellites. Hence, utilization of the frequency identification parameter maybe unnecessary and therefore, not included/not linked when considering next generation GLONASS satellites, e.g., GLONASS-K satellites. Additionally, signals supported by particular global positioning system (GPS) satellites can be indicated with the use of generic satellite identification. | 05-12-2011 |
