In table below are present list of feature that will be tested. There are six feature which are planned
to be test.Int
Expecting benefit of those feature
Feature Name Feature Name Benefit
Admission Block Redirection
Admission Block Redirection
Admission block redirection can redirect RRC-connections or Speech
calls, that are blocked by admission control in a cell,
to GSM or to another frequency. By this it is expecting that some
problem on accessibility of voice, when data traffic is increased to
be solved.
CE capacity for HSDPA Smartphone
Channel Element capacity for HSDPA Smartphones
Reducing consumptions of uplink channel element, in this form there will be need less capacity license.
Speech and 0 kbpsPacket Data
Speech & 0 kbpsPacket Data
Improve voice performance, better data resources utilization. In case of no data transferred, to be used speech
without consumption resources on data.
Speech 12.2 kbpsand HSDPA
Interactive 384/HSRAB combination
Conv. CS Speech + PSInteract. (16/HS)
Improve voice performance. Less consumption of resources. Current RAB combination with HSDPA is only speech + 64/HS. So it will be possible to handle speech with less speed on uplink. Only Conv. CS Speech + PS Interact. (16/HS) will be tested.
Conv. CS Speech + PSInteract. (128/HS)
Conv. CS Speech + PSInteractive 384/HS
Speech + EUL/HSSpeech 122 kbps and HSPA PS Interactive RAB Combination
It will be test if this feature improve voice performance when is
combined speech + HSPA.
EUL 2ms SoftCongestion Soft Congestion of 2 ms EUL users
2ms EUL users consumed high resources of channel element. In case of
congestion it is expected those users to be moved to 10ms, which consume
less resources.

will have positive impact, than those will be active from 27.07.2014 until the end of August.

Activation of features• Each feature will be tested separately• RNC license file will be upgraded• Based on request from Access Network, feature state of testing feature will be activated by Mobile Core
• Feature activation will be during the midnight. First impact will be checked during that night.
• If there is negative impact on performance, test feature will be immediately rolled back.
Risks due to testing those feature
• There is no risk due to testing those feature.
• There is expecting only positive impact.
• On Ericson documentation there is no mention any negative impact.
