• Flexible IP addressing concept - Applications can bind to interface IP addresses, virtual IP addresses or ali as IP addresses - IP addresses can be shared or dedicated across RATs and/or planes - SBTS M-plane binds to one IP address - In one extreme a SBTS can be operated with a single IP address for U-/C-/M-/S-plane,
in other extreme it can be operated for U- and C-plane IP addressing same as individual BTSs (except for M-plane which is always shared)

Supported IP versions : • On level of the IP interface IPv4 / IPv6 Dual Stack is supported • Which applications can use IPv6 is subject to features per Radio Access Technology, e.g. there are no plans for IPv6 for Packet Abis or IuB while it will be released for S1/X1 interface • IPv6 capabilities of a SBTS will thus be same as IPv6 capabilities of the individual Radio Access Technologies IP Security: • The SBTS provides the flexibility to freely map individual traffic flows to any IPsec security association (SA). Thus IPsec SAs can e.g. be • dedicated to a certain Radio Access Technology • dedicated to a certain plane of a certain Radio Access Technology • shared between multiple Radio Access Technologies („Common IPsec Tunnel“) 21
• The SBTS may be connected • to one IPsec gateway handling all traffic • to different IPSec gateways, e.g. • one per Radio Access Technology or • one for Management Traffic and other one for production traffic
22
Slide 22
• Flexible QoS concept • Two levels of scheduling/shaping are provided • 1st level queuing/scheduler/shaper “per policed or
bandwidth limited connection in the transport network” - Traffic flows can be freely allocated to 1st level
schedulers allowing to prioritize, shape and limit flows or combination of flows according to the preference of the operator • 2nd level scheduler/shaper “per phys. interface” • Common BTS mapping table for DSCP PHB and
DSCP p-bits

• Radio Access Technology-specific legacy Admission and Congestion Control mechanisms remain
applicable and operate independently in Single RAN BTS - WCDMA:
Connection Admission Control
- LTE:
Measurement Based Transport Admission Control
- GSM: Packet Abis Congestion Control
under the assumption that each Radio Access Technology has its own static configured bandwidth for committed bitrate traffic and other measures • Existing dimensioning plans and rules can be reused as the RAT specific admission control and pre-
emption mechanisms are reused

SR000924 * • The feature optimizes the investment to one battery backup system on a high-capacity BTS, especially on sites that operate as important transmission hub nodes. With Intelligent ShutDown, separate backup systems for BTS and transmission are unnecessary. • The SBTS with battery backup system supports an intelligent BTS site power shutdown
procedure in the event of an AC power failure. During the commissioning of each site, the operator can define different shutdown timers and priorities for the BTS sectors and carriers. • Intelligent shutdown is activated from Power systems by activating one external alarm (EAC)
lines to Flexi BTS.

SR000899 • TLS is a secure communication method for protecting the confidentiality
and integrity of m-plane communication protocols and file transfers (HTTPS, REST/TLS, WebUI/TLS, NE3S/TLS, LDAPs, Syslog/TLS) • The SBTS supports TSL 1.2 • TLS 1.2 is offered as default protocol version, if the peer doesn’t support TLS 1.2
the communication falls back to TLS1.0
• Cipher suites out of the for TLS 1.1. and TLS 1.2 pool are supported • Cipher with Perfect Forward secrecy are supported. • RC4 ciphers and ciphers with NULL integrity protection are not supported
• Compliant to normative Annex E of TS 33.301 • Session time based key negotiation according to RFC 5746 governed by a
configurable timer of 5 up 24 hours/86400 sec

SR000794 • Feature’s usage is checked by OSS • Uses CLS (Centralized License Server) and it extends OSS SWAM (SW Asset Monitoring) NetAct tool by the new
component SWEM (SW Entitlement Manager). • SWEM is checking feature's usage within NetAct database and it is verifying by inter-working to CLS existing license capacity 1. Protected feature related event: A. Configuration change notification B. SBTS measures feature usage value 2. SWEM is notified of event 3. SWEM checks notified value 4. SWEM requests complement from CLS 5. CLS reply to SWEM based available ‘feature pool’ capacity: 6. SWEM actions based on CLS reply: A. If OK SWEM to SBTS: a. No action b. Max value is increased B. If denial SWEM to SBTS: a. Initiate ‘General limiting actions reducing overall traffic volume b. Sets feature capacity limitation into previous value

SR000832 • Feature helps user to filter essential parameters regarding to
Flexi BTS and its transport for all radio technologies • Parameter categorization value of each Flexi BTS and
Transport CM parameter is Basic or Advanced • Configuration Management parameter categories are
common for GSM, WCDMA, LTE, SRAN and NetAct • Parameter categorization is automatically taken into use on
CM templates and GUI views of NetAct CM Editor and NetAct Plan Editor.
Flexi BTS CM parameter category views on NetAct CM Editor GUI: Basic All, Basic, Advanced Advanced
• NetAct CM Editor and NetAct CM Plan Editor GUI (graphical
user interface) allow to select if all parameters are shown or just basic, or advanced parameters from drop-down menu

Network resiliency for mcBSC – redundancy on network level • Network resiliency : GSM radio network controllers protected against
exceptional environmental incidents • Service availability : Continued service availability for end users with
protected GSM radio network
• Switchover to Backup mcBSC is performed in case of a total failure in the
Active mcBSC – Network Resiliency for mcBSC supports disaster recovery • mcBSC switchover is triggered by the operator but is otherwise
automatic – operator has the final decision • Backup mcBSC can be located at different site than the Active mcBSC –
Network resiliency for mcBSC supports geographical redundancy • One Backup mcBSC can support upto 16 Active mcBSCs – additional
equipment needed for network level redundancy is minimised Dual homed BTS
* will be released post-C5, as late feature
