For the purposes of the present document, the terms and definitions given in TR 21.905
and the following apply:
Application detection filter:
A logic used to detect packets generated by an application based on extended inspection of these packets, e.g., header and/or payload information, as well as dynamics of packet flows. The logic is entirely internal to a TDF or a PCEF enhanced with ADC, and is out of scope of this specification.
An identifier, referring to a specific application detection filter.
A decision consists of references to ADC rules, associated enforcement actions (for dynamic ADC rules) and TDF session attributes and is provided by the PCRF to the TDF for application detection and control.
A set of information enabling the detection of application traffic and associated enforcement actions. ADC rules are directly provisioned into the TDF and referenced by the PCRF.
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.
Detected application traffic:
An aggregate set of packet flows that are generated by a given application and detected by an application detection filter.
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. The association is identified by one or more UE Ipv4 addresses/ and/or 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.
IP Flow mapping:
IP flow mapping is used in Network-initiated NBIFOM mode when the UE wants to request the network to apply specific mapping of IP flows to 3GPP access or WLAN access. It applies to the same parameters as the NBIFOM routing rule.
Gateway Control Session:
An association between a BBERF and a PCRF (when GTP is not used in the EPC), used for transferring access specific parameters, BBERF events and QoS rules between the PCRF and BBERF. In the context of this specification this is implemented by use of the Gxx procedures.
Signalling between the GCS AS and the application client on the UE over the GC1 reference point as defined in TS 23.468
Identifies a usage monitoring control instance.
Multi-access IP-CAN session:
An IP-CAN session whose traffic can be routed over either a 3GPP access or a WLAN access or both. Each IP flow is routed at any single time only over one access.
An association between an IP-CAN session and the assigned TDF for the purpose of application detection and control by the PCRF. The association is identified by one UE Ipv4 address and/or Ipv6 prefix together with optionally a PDN represented by a PDN ID and a set of ADC rules to be applied by the TDF.
Usage monitoring control instance:
the monitoring and reporting of the usage threshold for input, output or total data volume or time of usage for the IP-CAN session/TDF session or the service data flows/application's traffic associated with the same monitoring key.
Presence Reporting Area:
An area defined within 3GPP Packet Domain for the purposes of reporting of UE presence within that area due to policy control and/or charging reasons. There are two types of Presence Reporting Area: "UE-dedicated Presence Reporting Area", and "Core Network pre-configured Presence Reporting Area".
Packet Flow Description (PFD):
A set of information enabling the detection of application traffic provided by a 3rd party service provider (from TS 23.203
In this specification, RAN rules refers to the set of RAN assistance parameter and RAN steering command handling for the steering of traffic between E-UTRAN or UTRAN and WLAN associated with RAN-controlled LTE-WLAN interworking or RAN-assisted WLAN interworking.
RAN user plane congestion:
RAN user plane congestion occurs when the demand for RAN resources exceeds the available RAN capacity to deliver the user data for a prolonged period of time.
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.
Service data flow:
Service data flow filter:
An aggregate set of packet flows carried through the PCEF that matches a service data flow template (from TS 23.203
Service data flow template:
a set of packet flow header parameter values/ranges used to identify one or more of the packet flows (from TS 23.203
The set of service data flow filters in a PCC rule or an application identifier in a PCC rule referring to an application detection filter, required for defining a service data flow (from TS 23.203
The network infrastructure connected to the 3GPP network over the SGi or Gi reference point that provides various IP-based services.
(S)Gi-LAN service function:
A function located in the (S)Gi-LAN that provides value-added IP-based services e.g. NAT, anti-malware, parental control, DDoS protection.
