Chapter 19 HCS Handover
19.1 Introduction to HCS
19.1.1 Definition
In 3G network, the so-called hot spots in radio communications may appear with the
increase of subscribers and traffic. This requires more cells to increase the network
capacity. More cells and smaller cell radius indicate that more frequent handovers of
UEs take place. For a UE in fast speed, frequent handovers reduce call quality,
increase uplink interference, and increase signaling load.
In this situation, Hierarchical Cell Structure (HCS) is required to divide cells into
different hierarchies.
Huawei RNC supports the HCS with 8 hierarchies, Figure 19-1 shows a HCS with
three hierarchies.
Figure 19-1 HCS with three hierarchies
The features of different cells are as follows:
macro cell
Large coverage
Continuous coverage networking
Low requirement on capacity
Fast-moving environment
Micro cell
Densely populated areas
High requirement on capacity
Slow-moving environment
Pico cell

RAN Feature Description Chapter 19 HCS Handover
Indoor coverage
Outdoor dead-area coverage
Where, the pico cell has the highest priority and the macro cell has the lowest priority.
19.1.2 Purposes
According to speed estimation, the RNC order the fast-moving UE to handover to the
cells of lower priority to reduce the number of handovers, and order the slow-moving
UEs to handover to the cells of higher priority to increase network capacity. The cells
of lower priority have larger coverage, and the cells of higher priority have smaller
coverage.

19.4.2 Overview
The HCS handover is divided into the following two phases:
I. Speed Estimation
The speed estimation on each hierarchy of an HCS cell falls into one of the following
types:
Fast speed
Normal speed
Slow speed
According to the number of changes of the best cell within time unit, speed estimation
algorithm estimates the moving speed of the UEs. See details as follows:
If the number of changes of best cell for a UE is above the fast-speed threshold,
this UE is decided in fast speed;
If the number of changes of best cell for a UE is below the slow-speed threshold,
this UE is decided in slow speed;
if the number of changes of best cell for a UE is between fast-speed threshold
and slow-speed threshold, this UE is decided in normal speed.
Huawei Technologies Proprietary

RAN Feature Description Chapter 19 HCS Handover
II. HCS Handover Based on Speed Estimation
After the moving speed of the UE is estimated, inter-hierarchy handover algorithm
initiates the corresponding handover based on this speed decision.
According to the results of speed estimation,
The UE in fast speed is handed over to the cell of lower priority.
The UE in slow speed is handed over to the cell of higher priority.
The UE in normal speed is not required to be handed over to any cell.
19.4.3 Speed Estimation for UE

III. Anti-Pingpong 1D Recording
During a given period of time, intra-frequency handover may be performed back and
forth across two or three cells, resulting in several event 1Ds of the same cell in the
statistic queue and thus inaccurate UE speed estimation.
Therefore, a mechanism is used for anti-pingpong 1D recording. During the recent
period Related length for 1D records, 1D event with repeated cell would not be
recorded.

record is restored to the state when the first event 1D occurs during the latest
[TRelateLength].
19.4.4 HCS Handover Based on Speed Estimation
I. Fast Inter-Hierarchy Handover
When the RNC decides that the UE is in fast speed, this UE is handed over from the
cell of high priority to the cell of low priority.
If the UE is located at the converged part between the cell of high priority and the cell
of low priority, the blink handover is initiated.
The target cell can be a UMTS cell or a GSM cell. The priority of intra-system inter-
frequency blind handover is higher than that of inter-system blind handover. If the
neighboring cell for blind handover is not configured or the blind handover fails, the
measurement is initiated for cells of low priority. The target cell is decided based on
the measurement report from the UE.
II. Slow Inter-Hierarchy Handover
When the RNC decides that the UE is in slow speed, this UE is handed over from the
cell of low priority to the cell of high priority.
Because the coverage of high priority cells is smaller than that of low priority cells,
slow speed inter-hierarchy handover algorithm needs to initiate the measurement for
Huawei Technologies Proprietary
10
RAN Feature Description Chapter 19 HCS Handover
cells of high priority, and then decides the target cell based on the measurement
report from the UE.
19.4.5 Signaling Procedure for HCS Handover
The signaling procedure for HCS handover is the same as that for inter-frequency
handover and inter-system handover. For detailed information, see section "inter-
frequency handover" and "inter-system handover."
19.4.6 HCS Handover and Other Features
The section describes the cooperation between HCS handover and other handover,
including:
The Cooperation between HCS Handover and Intra-Frequency
Handover
The Cooperation between HCS Handover and Inter-Frequency
Handover
The cooperation between HCS handover and inter-RAT handover
I. The Cooperation between HCS Handover and Intra-Frequency Handover
If HCS handover measurement is initiated when intra-frequency cell measurement is
ongoing and the intra-frequency handover is required, the HCS handover
measurement is not interrupted in the process of intra-frequency handover. After the
intra-frequency handover, if the best cell remains, the inter-hierarchy measurement
continues; and if the best cell changes, the fast speed estimation for the UE is
triggered.
For more information about intra-frequency handover, see section "intra-frequency
handover".
II. The Cooperation between HCS Handover and Inter-Frequency Handover
The causes to trigger inter-frequency handover include the follows:
Report of 2D event
Imbalanced load between inter-frequency cells
Estimation decision for UE speed in HCS
Where, the report of 2D event indicates that the inter-frequency handover based on
coverage is triggered, which is of high priority to be processed.
If the HCS handover algorithm is performing inter-frequency measurement when the
2D event is reported, the measurement control of inter-frequency measurement will
be updated according to the algorithm of inter-frequency handover based on
coverage.
Huawei Technologies Proprietary
11
RAN Feature Description Chapter 19 HCS Handover
If the RNC is performing inter-frequency measurement after the 2D event is reported,
that is, the inter-frequency measurement based on coverage, HCS handover will not
be processed.
When the inter-frequency handover based on load is required to be triggered due to
imbalanced load between inter-frequency cells, this handover will not be triggered if
the HCS handover algorithm is performing inter-frequency inter-hierarchy
measurement.
On the other hand, when the RNC is performing inter-frequency measurement for
handover based on load, the HCS handover cannot be initiated even the speed
estimation algorithm decides that the UE is in fast speed or in low speed.
For more information about inter-frequency handover, see section "inter-frequency
handover".
III. The cooperation between HCS handover and inter-RAT handover
It is strongly recommended that the inter-RAT handover to 2G is not used in HCS
handover.
To disable this procedure, make configurations as follows:
Disable HCS priority setting for GSM neighboring cells. For more details about
HCS priority settings, refer to Chapter 2 "UE Behaviors in Idle Mode."
For the UMTS layer whose HCS priority is next-higher to GSM layer, use
maximum value for Threshold for UE fast speed decision so that the fast inter-
hierarchy handover (from UMTS to GSM) will not be triggered.
For the UMTS layer whose HCS priority is next-lower to GSM layer, use
minimum value for Threshold for UE slow speed decision so that the slow
inter-hierarchy handover (from UMTS to GSM) will not be triggered.
