1 Application Scope
This document describes the feature Fast WCDMA Reselection at 2G CS Call Release(GU
Fast Return) for GBSS 13.0 , which is used to reduce the duration for MSs to camp on GSM cells,
shorten the selection time from 2G to 3G after call release at 2G.
The trial of this document was performed in XXX Operator for the sole purpose of delivering
PIP#1 feature project. Information contained in this document shall not be disclosed to any party
unless it is expressly authorized by Huawei.
The solution of this document is suit for RAN 13 or later version, the version of trial network
is,

2 Overview of Fast WCDMA Reselection at 2G CS Call Release
Feature
2.1 Summary
When an MS terminates a call in the GSM network, it camps on the UMTS network
according to the cell selection indicator after release information in the Channel Release message
instead of cell reselection from GSM to UMTS. The previously mentioned UMTS network
includes the UTRAN FDD and the UTRAN TDD.
2.2 Benefits
The cell reselection of the MS is accelerated. The MS can obtain services from the UMTS
network immediately after the call is released from the GSM network.

2.3 Description
In general, when the MS terminates a call in the GSM network, it camps on the cell in which
the call is released and then starts the measurement related to the cell reselection. When a UMTSneighboring cell meets the requirements for cell reselection, the MS camps on the UMTS network
after the cell reselection. The UMTS cell reselection is initiated after the MS receives the system
information and performs the related calculation. In this case, the time for the MS to access the
UMTS network is prolonged.
When the Fast UMTS Reselection at GSM CS Call Release feature is enabled, the BSS
figures out the best UMTS neighboring cell based on the measurement information on the UMTS
neighboring cells after the MS in the GSM network terminates a CS call. Then, the BSS sends the
MS the frequency information on the cell through the Channel Release message to instruct it to
camp on the UMTS cell. In this way, the MS can camp on a UMTS cell without related calculation,
thus accelerating cell reselection.
2.4 Impact
2.4.1 Impact on System Capacity
The Fast WCDMA Reselection at 2G CS Call Release feature reduces the duration for MSs
to camp on GSM cells and decreases the number of times that the MSs initiate services in GSM
cells. This increases the overall capacities of the GSM and WCDMA networks.
2.4.2 Impact on Network Performance
This feature allows MSs to reselect WCDMA cells after releasing calls in GSM cells. This
decreases the number of location updates and increases the CS paging success rate.
2.5 Prerequisites
Dependencies on Hardware
This feature does not have any special requirements for hardware.
Dependencies on Other Features
This feature does not depend on other features.

License
The license controlling this feature has been activated. For details on how to activate the
license, see Activating the GSM License. For details about license items, see Overview of Feature
Activation Guide. Other Prerequisites
The network involves the GSM network and the WCDMA network.
The UE supports the GSM and WCDMA frequency bands at the same time.
3 Feature Test
3.1 Test methods and tools
Objective
To verify that the MS preferentially camps on a 3G cell after the 2G call is released.
Tools:
Laptop with M2000 and WebLMT
Test phone: Iphone4
Procedure:
Procedure Expected Result
1 Activate the feature in the 2G cells
where the test locate at.The feature was activated successfully
2 Make a call where the 3G signal is poor
and the phone camps on 2G The call is established successfully under
2G
3 Move to the place where 3G signal is
strong enough and release the call
The call is released successfully. The MS
camps on the 3G cell within 10s.
4 Trace the signaling flow over the single
user CS trace in 2G and the UU interface in
3G.
The downlink Channel Release message
traced on the single user CS trace in 2G
carries the information element
cell-selection-indicator-after-release .
And UU interface in 3G carries the
message RRC_UL_DIR_TRANSF .
5 Deactivate the feature and repeat steps
2 to 4.
The reselection time from 2G to 3G is
longer than 30s and there are no
cell-selection-indicator-after-release

From above pictures, we can see that there have 3G neighbor cells in 2G measurement result
message, and the UE reselect to 3G 7 seconds after the call released from 2G. There have
cell-selection-indicator-after-release information element and target 3G cell information in
channel release message.

4.3.4 Comparison
From above pictures, we can see that,
The 3G signal occupation is 21.6% before the feature is activated; the 3G signal occupation is
69.7% after the feature is activated.
From the results above we can see that the percentage of 3G increased after implementing the
feature, because the feature shortens the selection time from 2G to 3G after call release at 2G.
