For the purposes of the present document, the terms and definitions given in 3GPP
and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in 3GPP
5G enhanced positioning area:
a subset of the 5G positioning service area that is assumed to be provided with additional infrastructure or deploy a particular set of positioning technologies to enhance positioning services.
The enhanced positioning service area represents for example a factory plant, a dense urban area, an area along a road or railway track, a tunnel and covers both indoor and outdoor environments.
5G LAN-type service:
a service over the 5G system offering private communication using IP and/or non-, i.e. UEs that are members of the same 5G LAN-VN IP type communications.
5G LAN-virtual network:
a virtual network capable of supporting 5G LAN-type service.
5G satellite access network:
5G access network using at least one satellite.
5G positioning service area:
a service area where positioning services would solely rely on infrastructures and positioning technologies that can be assumed to be present anywhere where 5G is present (e.g. a country-wide operator-supplied 5G network, GNSS, position/motion sensors).
This includes both indoor and any outdoor environments.
a UE is in active communication when it has one or more connections established. A UE may have any combination of PS connections (e.g. PDP contexts, active PDN connections).
percentage value of the amount of simultaneous active UEs to the total number of UEs where active means the UEs are exchanging data with the network.
area traffic capacity:
total traffic throughput served per geographic area.
communication service availability:
percentage value of the amount of time the end-to-end communication service is delivered according to an agreed QoS, divided by the amount of time the system is expected to deliver the end-to-end service according to the specification in a specific area.
The end point in "end-to-end" is assumed to be the communication service interface.
The communication service is considered unavailable if it does not meet the pertinent QoS requirements. If availability is one of these requirements, the following rule applies: the system is considered unavailable if an expected message is not received within a specified time, which, at minimum, is the sum of maximum allowed end-to-end latency and survival time.
direct device connection:
the connection between two UEs without any network entity in the middle.
direct network connection:
one mode of network connection, where there is no relay UE between a UE and the 5G network.
This is the condition that a government decides when to initiate and terminate, e.g. a natural disaster. When this condition applies, users may have the opportunity to mitigate service interruptions and failures.
Disaster Inbound Roamer:
A user that (a) cannot get service from the PLMN it would normally be served by, due to failure of service during a Disaster Condition, and (b) is able to register with other PLMNs.
This is the special roaming policy that applies during a Disaster Condition.
the time that takes to transfer a given piece of information from a source to a destination, measured at the communication interface, from the moment it is transmitted by the source to the moment it is successfully received at the destination.
a service containing the operator's own application(s) and/or trusted third-party application(s) in the Service Hosting Environment, which can be accessed by the user.
indirect network connection:
one mode of network connection, where there is a relay UE between a UE and the 5G network.
a type of UE which is dedicated for a set of specific use cases or services and which is allowed to make use of certain features restricted to this type of UEs.
An IoT device may be optimized for the specific needs of services and application being executed (e.g. smart home/city, smart utilities, e-Health and smart wearables). Some IoT devices are not intended for human type communications.
a set of network functions and corresponding resources necessary to provide the required telecommunication services and network capabilities.
a radio access network connecting to the 5G core network which uses NR, E-UTRA, or both.
a network that is intended for non-public use.
the new 5G radio access technology.
positioning service availability:
percentage value of the amount of time the positioning service is delivering the required position-related data within the performance requirements, divided by the amount of time the system is expected to deliver the positioning service according to the specification in the targeted service area.
positioning service latency:
time elapsed between the event that triggers the determination of the position-related data and the availability of the position-related data at the system interface.
a service that requires priority treatment based on regional/national or operator policies.
a communication between two or more UEs belonging to a restricted set of UEs.
an isolated network deployment that does not interact with a public network.
a dedicated network slice deployment for the sole use by a specific third-party.
relative positioning is to estimate position relatively to other network elements or relatively to other UEs.
in the context of network layer packet transmissions, percentage value of the amount of sent network layer packets successfully delivered to a given system entity within the time constraint required by the targeted service, divided by the total number of sent network layer packets.
a space-borne vehicle embarking a bent pipe payload or a regenerative payload telecommunication transmitter, placed into Low-Earth Orbit (LEO) typically at an altitude between 300 km to 2 000 km, Medium-Earth Orbit (MEO) typically at an altitude between 8 000 to 20 000 k m, or Geostationary satellite Earth Orbit (GEO) at 35 786 km altitude.
direct connectivity between the UE and the satellite.
a NG-RAN which uses NR in providing satellite access to UEs.
geographic region where a 3GPP communication service is accessible.
The service area can be indoors.
For some deployments, e.g. in process industry, the vertical dimension of the service area can be considerable.
the uninterrupted user experience of a service that is using an active communication when a UE undergoes an access change without, as far as possible, the user noticing the change.
In particular service continuity encompasses the possibility that after a change the user experience is maintained by a different telecommunication service (e.g. tele- or bearer service) than before the change.
Examples of access changes include the following. For EPS: CS/PS domain change. For EPS and 5G: radio access change, switching between a direct network connection and an indirect network connection.
Service Hosting Environment:
the environment, located inside of 5G network and fully controlled by the operator, where Hosted Services are offered from.
the time that an application consuming a communication service may continue without an anticipated message.
Time to First Fix (TTFF):
time elapsed between the event triggering for the first time the determination of the position-related data and the availability of the position-related data at the positioning system interface.
An equipment that allows a user access to network services via 3GPP and/or non-3GPP accesses.
user experienced data rate:
the minimum data rate required to achieve a sufficient quality experience, with the exception of scenario for broadcast like services where the given value is the maximum that is needed.
a link which provides an interconnection between 5G network nodes and/or transport network using 5G radio access technology.
