Abstract: 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. A further method for obtaining a service by a terminal related to an assistance server comprising sending by the terminal a capability request, and receiving, in the terminal, information indicative of capabilities related to the assistance server, wherein the information indicative of capabilities comprises indications of available assistance related to the assistance server.

Abstract: Session parameters and/or information regarding session parameters are provided to a target device from a location server in a periodic assistance session. For example, the location server starts an unsolicited periodic assistance session, and transmits information indicating the unsolicited assistance session is periodic as well as any relevant session parameters to the target device. The location server may change session parameters “on the fly,” and inform the target device of the modified session parameters. The target device may initiate a session and requests certain parameters, to which the location server responds with an indication as to what parameters the target device will actually receive. Additionally, the target device may modify the session parameters, and the location server can respond to the target indicating whether or not the modification was accepted or if the modification was accepted in a modified form.

Abstract: Systems and methods are provided enabling a terminal to send an area shape capability indication to a location server. Depending on the use case scenario, the location server can perform at least one of the following operations, before sending the area event request to the terminal. The location server can select a shape that is both allowed by the requesting entity and supported by the terminal. Alternatively, the location server can convert the requested shape into a supported one by some approximation function if the requested shape(s) is/are not supported by the terminal. Furthermore, the location server can choose to terminate the session if the terminal does not support any of the requested (allowed) shapes. It should be noted that different priorities can be assigned to or associated with various area shapes as well.

Abstract: Systems and methods are provided allowing for a vendor-defined payload in a standardized user-plane location solution/protocol, where proprietary extension support is introduced into one or more standardized solutions. In accordance with a first embodiment, a location payload consists of structures for transferring requests, assistance data, measurements and positioning instructions. Therefore, a proprietary extension is included in each of these structures so that, for example, proprietary assistance data can be requested in an appropriate structure. In accordance with another embodiment, a proprietary extension is introduced at the highest abstraction level. For example and in an actual implementation, a vendor can define that in the beginning of the proprietary payload, the proprietary extension is defined, whether the proprietary payload contains a request, assistance, etc.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

The received or assembled message is provided for transmission. At a receiving end, the reference time identifier and additional information are extracted from a received message, and the additional information is processed taking account of the reference time identifier. Alternatively or in addition, the message may include a reference time, which is indicated in units of seconds.

Abstract: 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.

Abstract: 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.
