8 Performance requirements for the Evolved Packet System

22.2783GPPService requirements for the Evolved Packet System (EPS)TS

The Evolved Packet System comprises the Evolved Packet Core together with the evolved radio access network (E-UTRA and E-UTRAN).

The performance objectives for the Evolved Packet System include higher user data rates, reduced latency, improved system capacity and coverage, reduced network complexity and lower operating costs.

The Evolved Packet System shall meet or exceed the following performance criteria:

a) The radio access network shall be capable of supporting instantaneous peak packet data rates of 100 Mbps on the radio access bearer downlink to the UE and 50 Mbps on the uplink.

b) The Evolved Packet System shall be capable of providing lower user and control plane latency when compared to existing 3GPP access networks. The maximum delay should be comparable to that for fixed broadband Internet access technologies. [e.g. less than 5ms in ideal conditions]

c) The system shall be capable of supporting large volumes of mixed e.g. voice, data and multimedia traffic. Enhanced load balancing and steering of roaming methods should be used to minimise cell congestion.

d) The level of system complexity and mobility management signalling shall be optimised to reduce infrastructure and operating costs. UE power consumption shall also be minimised accordingly.

e) For the Evolved Packet System the interruption time during handover of RT and NRT services shall be kept to minimum and shall not exceed the values defined in TR 25.913[4].

f) The Evolved Packet System shall be capable of providing low latency mobile broadband communication services with the following requirements:

– maximum delay in the EPS of 10 ms for 98% packets,

– 99,9999% reliability excluding the delayed packets.

g) The Evolved Packet System shall be capable of providing low latency communication services with maximum delay in the EPS of 10 ms and 99,99% reliability.

h) The Evolved Packet System shall be capable of providing ultra reliable low latency communication services (e.g., wireless road-side infrastructure backhaul as described in TS 22.261 [30]) with maximum delay in the EPS of 30 ms and 99,999% reliability.

i) The Evolved Packet System shall be capable of providing ultra reliable low latency communication services with maximum delay in the EPS of 5 ms and 99,999% reliability.

j) To support ultra reliable low latency communication services, the Evolved Packet System shall support the transmission over the radio interface of a packet of 32 bytes with a reliability of 99,999% and a user plane latency of 1ms, as described in TR 38.913 [31].
