Introduction
To ensure competitiveness in a longer time frame an evolution of the overall 3GPP system needs to be considered.
This document compiles requirements to ensure that an Evolved Packet System can cope with the rapid growth in IP
data traffic and demanding requirements for new multimedia type of applications in terms of performance and quality,
delivered to the user, whilst at the same time enabling cost effective deployment and operation.
The Evolved Packet System is characterised by:
- Reduced latency
- Higher user data rates equating to broadband performance
- Improved system capacity and coverage
- Lower operational costs

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in TR 21.905 [2] and the following apply.
Communication Range: The range between UEs and /or between UEs and eNBs such that ProSe Communication is
possible.
Evolved Packet System: is an evolution of the 3G UMTS characterized by higher-data-rate, lower-latency, packet-
optimized system that supports multiple RATs. The Evolved Packet System comprises the Evolved Packet Core
together with the evolved radio access network (E-UTRA and E-UTRAN).
Firewall: a functional entity which blocks or permits the flow of various traffic types based on a set of policy rules and
definitions
EPC Path: the user plane communication path through EPC.
Open ProSe Discovery: is ProSe Discovery without explicit permission from the ProSe-enabled UE being discovered.
ProSe Broadcast Communication: a one-to-all ProSe E-UTRA Communication, between all authorized Public Safety
ProSe-enabled UEs in proximity, by means of a common ProSe E-UTRA Communication Path established between
these UEs.
ProSe E-UTRA Communication: a ProSe Communication using a ProSe E-UTRA Communication path.
ProSe-assisted WLAN direct communication: a ProSe Communication using a ProSe-assisted WLAN direct
communication path.
ProSe Communication path: the communication path supporting ProSe Communication. The communication path of
a ProSe E-UTRA Communication (ProSe E-UTRA Communication path) could be established e.g. directly between the
ProSe-enabled UEs using E-UTRA, or routed via local eNB(s). The communication path of a ProSe-assisted WLAN
direct communication (ProSe-assisted WLAN direct communication path) is established directly between the ProSe-
enabled UEs using WLAN.
ProSe Group Communication: a one-to-many ProSe E-UTRA Communication, between more than two Public Safety
ProSe-enabled UEs in proximity, by means of a common ProSe E-UTRA Communication path established between the
Public Safety ProSe-enabled UEs.
ProSe UE-to-Network Relay: is a form of relay in which a Public Safety ProSe-enabled UE acts as a ProSe E-UTRA
Communication relay between a Public Safety ProSe-enabled UE and the ProSe-enabled network using E-UTRA.

3GPP TS 22.278 version 13.5.0 Release 13 8 ETSI TS 122 278 V13.5.0 (2018-10)
ProSe UE-to-UE Relay: is a form of relay in which a Public Safety ProSe-enabled UE acts as a ProSe E-UTRA
Communication relay between two other Public Safety ProSe-enabled UEs.
ProSe-enabled Network: a network that supports ProSe Discovery and/or ProSe Communication.
Proximity: proximity is determined ("a UE is in proximity of another UE") when given proximity criteria are fulfilled.
Proximity criteria can be different for discovery and communication.
Range Class: Rough indication of distance for use in ProSe Discovery, for example, based on geographical distance,
radio conditions.
Restricted ProSe Discovery: ProSe Discovery that only takes place with explicit permission from the ProSe-enabled
UE being discovered.
Service Continuity: The uninterrupted user experience of a service that is using an active communication (e.g. an
ongoing voice call) when a UE undergoes a radio access technology change or a CS/PS domain change without, as far
as possible, the user noticing the change.
Note: In particular Service Continuity encompasses the possibility that after a RAT / domain change the user
experience is maintained by a different telecommunication service (e.g. tele- or bearer service) than
before the RAT / domain change.
Service Reachability: Functionality to enable user access to PLMN IP-based services from outside of the PLMN's
domain via non-3GPP access technologies that have IP traffic-flow restrictions (e.g. such as firewall functions that only
allow HTTP traffic).

4 General description
4.1 Objectives
The Evolved Packet System is a higher-data-rate, lower-latency, packet-optimized system that supports multiple RATs.
The focus of the Evolved Packet System work is on enhancement of Packet Switched technology to cope with rapid
growth in IP traffic.
The objectives of the Evolved Packet System are to:
- Provide higher data rates, lower latency, high level of security and enhanced QoS;
- Support a variety of different access systems (existing and future), ensuring mobility and service continuity
between these access systems;
- Support access system selection based on a combination of operator policies, user preference and access network
conditions;
- Realise improvements in basic system performance whilst maintaining the negotiated QoS across the whole
system;
- Provide capabilities for co-existence with legacy systems and migration to the Evolved Packet System.
