Abstract: In a method in association with a communication system a request for a connection is signaled between a user equipment and another party. The requested connection is then analyzed. Subsequent to detection that location information is required in association with the requested connection, a process for determining information about the location of the user equipment is activated. First information in association with the determining process is communicated on a control plane between the user equipment and the communication system, while second information in association with the determining process is communicated on a user plane between the user equipment and the communication system. An arrangement in association with location services and a user equipment capable of providing location information is also disclosed.

Abstract: A method, apparatus and computer program product are provided that enable a method for providing location information to be selected based upon a determination, such as a minimization, of the consumption of location server resources that will be consumed by the method. The method, apparatus and computer program product may determine a selected location method from a set of location methods based on predetermined selection criteria. Specifically, the selected location method may be selected to meet a location accuracy requirement specified in a request for location information while consuming a determinable, such as a minimum, amount of resources. The predetermined selection criteria may be updated over time such that method, apparatus and computer program product are self-learning.

Abstract: A method for establishing a media for communications in association with a location information service provided in association with a communication system is disclosed. In the method a user equipment is provided with information enabling the user equipment to communicate on a user plane connection with at least one location service entity when the user equipment is visiting a communication network other than a home network of the user equipment. This information may then be used for establishment of a user plane connection in the visited communication network between the user equipment and a location service entity.

Abstract: Systems and methods of sending a secure user plane location (SUPL) session initiation message from a location platform to a SUPL-enabled terminal are provided. When a network-based application has an internet protocol (IP) connection with the SUPL-enabled terminal using general packet radio service (GPRS) and needs location information regarding the SUPL-enabled terminal, the network-based application indicates an available GPRS session in mobile location protocol standard location immediate request. The location platform uses an application server hosting the network-based application to request starting a SUPL-enabled terminal-initiated location procedure. Alternatively, the location platform can determine whether a SUPL-enabled terminal has an active IP connection from an authentication, authorization, and accounting server. The IP address of the SUPL-enabled terminal is returned to the location platform, upon which a SUPL session initiation message is sent to an associated GPRS Gateway Support Node.

Abstract: The present invention relates to selection of sites of a communication system for measurement units that are for measuring a feature of wireless signals so that the location of a wireless station may be determined based on the measurement. Each measurement unit provides a measurement coverage. In the method a first set of information is defined, said first set relating to sites that are possible locations for the location measurement units and to the coverage provided by the site if it is provided with a measurement unit. A second set of information is defined that relates to signalling environment within the sites. Based on the defined first and second sets of information, a third set of information is defined, said third set associating each site with access entities of the communication system. Based on the third set of information, appropriate sites can be selected for the location measurement units.

Abstract: The invention proposes a method for locating a network element, comprising the steps of obtaining (S1) the coordinates (xS, yS) of a second network element (BTS) to which the first network element (MS) is connected or attached; detecting (S2) a serving area (S), which is served by the second network element (BTS); detecting (S3) a propagation delay of the first network element with respect to the second network element (BTS); determining (S4) a propagation delay depending area (C), which is an area having a distance to the second network element (BTS) based on the propagation delay and a width based on the propagation delay; and forming (S5) an intersection area (I) of the serving area (S) and the propagation delay depending area (C); wherein a location estimate of the first network element (MS) is determined (S6) from the intersection area (I). Thus, an uncertainty area where a first network element is located can be reduced and the location accuracy can be improved.

Abstract: A method of providing information regarding the location of a mobile user equipment (1) in a system wherein the location is determined based on information signalled from entities (10) of a positioning system and assistance data signalled from a station (5) of a communication system. In the method the likely location of the mobile user equipment relative to the station is first determined. Based on the determined likely location, an estimate of the delay in transmitting a signal from the station to the mobile user equipment is estimated. Assistance data is then signalled from the station to the mobile user equipment, said assistance data comprising information about the timing of the positioning system. A more accurate location determination is accomplished at the user equipment based on signals from the entities of the positioning system, the assistance data and said estimated delay.

Abstract: Records are produced describing how a passenger uses a transport system in relation to other passengers. A transport server (1001) receives (203, 401) an identifier of a requested drop-off point and determines (204, 205, 403, 407) an identifier of a requested pick-up point. It also determines (405, 413, 803) a list of stopping point identifiers, which list includes the identifiers of the requested pick-up and drop-off points and constitutes an itinerary for a transport vehicle. A list of those passengers is determined (804) that have requested transport in the same vehicle. For each passenger on the list of passengers, there is determined (801, 804, 901, 904) which passenger-specific group of legs between stopping points belong to the transport requested by that passenger, and calculated (802, 805, 806, 807, 808, 902, 904, 905, 906, 907) a record that represents the relation between the passenger-specific group of legs and those other groups of legs that are specific to other passengers.
