Gb over IP Considerations
Gb over IP license must be installed
and activated
In dynamic IP configurations the SGSN side must be
created firstIn static IP configurations it does not matter which end (BSC/SGSN) is created first
Static configuration can use only logical IP addresses
Both IPv4 and IPv6 are supported in the NSN implementation of Gb over IP
DNS names can be used instead of IP addresses if a DNS server address is specified in the BSC

Static Gb IP configuration
Configuration parameters are configured to both ends
statically and not transferred over Gb.
Operator creates all NS-VCs with
fixed remote IP endpoints: address, port number, signaling weight and data weight. BSC software can decide that static configuration is used, if PRE parameter is set to No (N) in creation of first NS-VC in NSE.
NS-VC configurations on both sides (BSS and SGSN) must match

Dynamic Gb IP Configuration
Configuration parameters are transferred over Gb in
the initialization phase.
Only one address and port pair of the
remote end SGSN is needed to establish NS-VC configuration on Gb. These parameters are attributes of the preconfigured SGSN IP endpoint. BSC software can decide that dynamic configuration is used, if PRE parameter is set to Yes (Y) when creating the first NS-VC in NSE.

Dynamic Abis Allocation Introduction
GSM/GPRS radio timeslot data can be fitted
into one 16 kbit/s sub timeslot in Abis-if
EDGE introduces
data throughputs up to ca. 60 kbit/s over air up to 5*16 kbit/s sub timeslots needed over Abis/radio timeslot
BTS internal traffic can not be fit into one D-bus (2 Mbit/s)
UltraSite has four D-buses
Abis capacity needs to be expanded (even up to 4 times higher)
Dynamic Abis Allocation
1*16 kbit/s "Master" as fixed/radio timeslot
1 …4*16 kbit/s "Slaves" dynamically as per needed/radio timeslot

Слайд 45RN28176EN14GLA0
Fixed channels and EDAP
For each GPRS radio timeslot on each
EDGE TRX, one fixed 16-kbps channel is allocated on the
Abis for the transfer for PCU master data frames.PCU slave data frames are allocated in a common pool, the EDAP (EDGE Dynamic Abis Pool).
12 PCM timeslots as the maximum size of EDAP.
A master channel and its slave channels and therefore the entire EDAP must be on the same Abis PCM.

Functional Description
When CS3-CS4 option is on, and the Dynamic Abis
pool and (E)GPRS territories are created then all GPRS coding
schemes (CS1-CS4) are available for data transfer.The current GPRS Link Adaptation algorithm in the PCU/RLC is replaced with a new one, which covers also CS3 and CS4.
A data block of CS2-CS4 is transferred in one PCU master Data Frame and one PCU Slave Data Frame through the Abis interface. CS1 data block fits in one PCU Master Data Frame.
