For the purposes of the present document, the terms and definitions given in TR 21.905
and the following apply:
Application Function (AF):
element offering application(s) that use IP bearer resources
application level session established by an application level signalling protocol offered by the AF that requires a session set-up with explicit session description before the use of the service.
Attribute-Value Pair (AVP):
See RFC 6733
, corresponds to an Information Element in a Diameter message.
PCRF process of associating IP flows described in AF Service Information with IP-CAN bearers.
The number of bits (denoted in units of bits, kbits, etc.) that are conveyed or processed per unit of time. The bit rate in bit/s can be abbreviated with bps. This specification uses SI (International System of Units) prefixes as unit prefixes, which strictly refer to the power of 10, and shall not be used for the power of 2. For example, 1 kbit/s represents 1000 bit/s or 1 Mbit/s represents 1000 kbit/s and so on.
IP transmission path of defined capacity, delay and bit error rate, etc. See TR 21.905
for the definition of bearer.
association between a UE and an IP network (for GPRS, APN). The association is identified by one UE Ipv4 address and/or one Ipv6 prefix together with a UE identity information, if available, and a PDN represented by a PDN ID (e.g. an APN). An IP-CAN session incorporates one or more IP-CAN bearers. Support for multiple IP-CAN bearers per IP-CAN session is IP-CAN specific. An IP-CAN session exists as long as the related UE Ipv4 address and/or Ipv6 prefix are assigned and announced to the IP network.
unidirectional flow of IP packets with the same source IP address and port number and the same destination IP address and port number and the same transport protocol. Port numbers are only applicable if used by the transport protocol.
A session for which priority treatment is applied for allocating and maintaining radio and network resources to support the Multimedia Priority Service (MPS). MPS is defined in TS 22.153
A specific user data flow carried through the PCEF. A packet flow can be an IP flow.
set of information enabling the detection of a service data flow and providing parameters for policy control and/or charging control.
is an architectural style consisting of a coordinated set of architectural constraints applied to components, connectors, and data elements, within a distributed hypermedia system applied to the development of web services.
Restricted local operator services:
communication services provided by an operator that involve either automated or human assistance (e.g. credit card billing, directory assistance, customer care) for which successful authentication is not necessary.
set of information conveyed from the AF to the PCRF over the Rx interface to be used as a basis for PCC decisions at the PCRF, including information about the AF session (e.g. application identifier, type of media, bandwidth, IP address and port number).
service data flow:
An aggregate set of packet flows.
