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.

Providing location information

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.

Method, apparatus and computer program product for self-learning location method selection logic

A wireless communications network for providing location services comprising: a network element comprising storage means for storing network information of mobile stations, said network information including location information relating to the location of a mobile station and a subscriber identity; a passive location data storage entity for storing passive location data and subscriber identities; and means for transferring the location information and subscriber identity from the network element to the passive location data storage entity whereby the location information constitutes said passive location data for providing location services to a location services client.

Location services

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.

Providing location information for user equipment in a visited network

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. User Datagram Protocol is utilized instead of Wireless Datagram Protocol.

Secure user plane location session initiation improvement

A method of providing information regarding the location of a mobile user equipment () in a system wherein the location is determined based on information signalled from entities () of a positioning system and assistance data signalled from a station () 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.

Provision of location information

There is disclosed a method of supporting location services in an unlicensed mobile access network, comprising transferring location related information between one or more mobile stations and a network control element.

Location services for unlicensed mobile access

A method for providing time information comprises sending time information to at least one communications device and receiving information indicating error in received time information from at least one of said at least one communications device, said error in received time information having been determined in a communications device. In a communications device, first time information from a communications system is received and second time information with respect to an external time frame is determined. Thereafter an error in first time information based on at least said second time information is determined, and information indicating said error in said first time information is sent to said communications system. A communications device, a communications system and a network element for a communications system are also discussed.

Providing time information

A method of controlling a satellite communication system, a timing unit, and a control unit of a timing unit. The method comprises dividing the coverage area of the satellite communication system into one or several geographical areas; positioning one or several timing units in at least one geographical area; determining which of the satellites of the satellite communication system are visible in each particular geographical area; controlling the timing unit with a control unit, in order to minimize the time difference within the system, to listen to one or several satellites visible in each particular geographical area, the signals received from the satellites by the timing unit fulfilling a predetermined condition; synchronizing a predetermined number of geographical areas with each other by means of the control unit of the system such that the time difference within the system is minimized in a predetermined combination area of geographical areas.
