9 System QoS, Capacity, Scalability and High Availability
RADWIN 3G Small Cell solution scalability is defined in terms of number of Servicesubscribers with required quality of service for a set of provided services.
RADWIN 3G Small Cell solution scalability is handled by its components capacity as wellas the communication links throughputs.
9.1 Quality of Service
9.1.1 RADWIN UTRAN QoS Management
The solution uses all-IP transport infrastructure, supporting QoS traffic prioritization,ensuring the required bandwidth for high priority services (e.g. Voice).
The RADWIN 3G Small Cell solution uses Differentiated Services Code Point (DSCP)marking over Iuh interface. The support is provided on for traffic quality management inaccordance with the following standards: 3GPP TS 25.414 V9.0.0 (2009-12) [7], 3GPPTS 25.468 V9.2.0 (2010-06) [10], 3GPP TS 25.469 V9.2.0 (2010-06) [11], IETF RFC2474 [58], IETF RFC 4594 [71], IETF RFC 4960 [73].
The user data and signaling traffic from a UE is forwarded by RADWIN 6000 Small Cellto the RADWIN 6800 Small Cell GW over the Iuh interface using the IP as a networklayer, where RTP/RTCP or GTP over UDP/IP provide transport for the user data andSCTP/IP for the control signaling over Iuh.
These data and control packets traverse the RADWIN BWBH and different SP datanetworks before reaching the RADWIN 6800 and vice-a-versa for the downlink traffic
while different bearers are used:
RTP carries jitter-sensitive real-time media data such as voice and video
RTCP carries media reception/transmit feedback that is not delay sensitive
GTP carries generic, non-media data
RADWIN 6000 Small Cell supports DSCP marking of the traffic on Iuh for the uplinktraffic towards the Small Cell GW by manual provisioned ToS per RAB separately forvoice, video and data.
RADWIN 6800 Small Cell GW supports DSCP marking by mirroring of the traffic on theIuh for downlink traffic towards the Small Cells and for uplink traffic towards the CN. IPtransport is used for IuCS or IuPS.
9.1.2 RADWIN Wi-Fi QoS Management
The RADWIN 6000 Wi-Fi module uses IEEE 802.11WMM standard for QoSprioritization.
