Field Issue 10D Issue 10E

Description This parameter indicates the

transport media used for the user

plane connections with air interface

channel type and UMTS

traffic class based selection

method. In case of IP based Iub

only the value "IP Iub" is possible,

and with Dual Iub interface

the user plane connections

carried over the IP transport can

be controlled with other values.

In each transport bearer setup,

the RNC selects either ATM or IP

transport media for the new

transport bearer based on the

bitmask values (Common

Channel, Signaling Radio Bearer

or any other Radio Bearer setup).

If all of the values are zero, then

the traffic is carried on top of the

ATM. Bit value 0 means that the

corresponding traffic type is

carried over ATM. Bit value 1

means that the corresponding

traffic type is carried over IP.

To enable the IP transport, the

following licenses are required:

IP Based Iub: Bit 0, IP Iub, is the

only possible value once the

NBAP links are configured on top

of IP with the IPNB object. Dual

Iub: Bit 5 NRT DCH, Bit 1 NRT

HSDPA, Bit 2 NRT HSUPA Dual

Iub and Streaming QoS for

HSPA: Bit 3 Streaming HSDPA

and Bit 4 Streaming HSUPA If

the DCH NRT traffic is configured

to be carried over IP, then

HSDPA NRT and HSUPA NRT

must also be carried over the IP

transport path.

The parameter indicates the

transport media used
