Intra-frequency handover refers to the handover performed between cells under
the same frequency point of UTRAN. The intra-frequency handover can be
triggered based on Ec/N0 or RSCP measurement through the parameter
IntraMeasQuan.Intra-frequency handover is measurement-based handover.
Intra-frequency measurement contains active set measurement, monitored set
measurement and detected set measurement.
The active set refers to the collection of cells retaining radio connection with UE.
The monitored set refers to the collection of cells retaining no radio connection
with UE but requiring measurement by sending the intra-frequency measurement
control message to UE.
The detected set refers to the collection of intra-frequency cells except cells in
the active set and monitored set.

ZTE uses Event 1A、Event1B、Event1C、Event1D for intra-frequency handover.
Event 1A: The quality of target cell ameliorates and enters a reporting range of
relative active set quality. It can be used for adding cell to the active set.
Event 1B: The quality of target cell worsens and leaves a reporting range of
relative active set quality. It can be used for dropping cell from the active set.
Event 1C: The quality of a cell in non-active set is better than that of a cell in
certain active set. It can be used for swapping into and out of the active set.
Event 1D: The best cell changes. It can be used for adding cell to the active set,
swapping into and out of the active set, intra-frequency hard handover or
inter-frequency load balance.

Add a cell into the active set (the cell outside the active set reports Event 1D and
the number of links in the active set does not reach the maximum).

When there are many cells in an active set, the number of intra-frequency adjacent
cells in the active set may exceed 32, the maximum number of adjacent cells as
restricted in the protocol. In that case, some intra-frequency adjacent cells must be
dropped to ensure there are only 32 adjacent cells in the neighboring cell list. Having
minimal impact on users in the active set, these dropped cells are those with poorest
signal quality or remotest geographical location. Therefore, each intra-frequency
adjacent cell is configured with a priority level.
The background configuration parameter MeasPrio is used to define the priority of
adjacent cells and includes three values (0: High priority; 1: Medium priority; 2: Low
priority). The specific value of MeasPrio must be set by the network planning engineer
based on existing network situation (for example, adjacent cell quality and

The detected set handover is controlled through the parameter DetSetHoSwch ，If the
detected set handover is enabled, then the RNC handles the cell in the detected set in
the same way as it does in the monitored set, that is, to make decision about handover.
If the detected set handover of the best cell is enabled and there are over 32 adjacent
cells, the detected set measurement will be initiated. Initiation strategy: Change “1A
Triggering condition 2” into “Detected set cells and monitored set cells”, and “Reporting
cell status” into “Report all active set cells + cells within monitored set and/or detected
set on used frequency”, that is, perform measurement report of active set, monitored
set and detected set concurrently by sharing the same set of handover measurement
parameters.
If the detected set handover of the best cell is disabled or there are less 32 adjacent
cells, then change “1A Triggering condition ” into “Monitored set cells” and “Reporting
cell status” into “Report cells within active set and/or monitored set cells on used

49,162,206 123,195,24 0,102,255 The inter-frequency handover is a feature in which the UE hands over from one frequency
point of UTRAN to another one. It can either be handover based on inter-frequency measurement, or blind handover based on shared coverage or inclusion.
The prerequisite for measurement-based inter-frequency handover is that UE performs quality measurement of non-current serving carrier. For inter-frequency measurement in CELL_DCH state, UE needs to initiate compressed mode unless it has double-receiver. The
compressed mode has a impact on both the resource consumption (for example, downlink power and uplink interference) and UE (for example, the transmit power and battery
consumption), so inter-frequency measurement is only initiated when the radio quality of current serving carrier is poor .
Upon receiving the inter-frequency measurement results from UE, the RNC makes a decision about inter-frequency handover, and hands over UE to the target frequency point and cell

ZTE UMTS support event 2A、2B、2C、2D、2F for inter-frequency
handover.
Among all inter-frequency measurement events, Event 2D and Event 2F only
involve measurement of working carrier frequencies, so the compressed
mode is not required during measurement and extra overhead will not be
brought about to both UE and RNC. The compressed mode and event 2A、
2B or 2C can be enabled and disabled based on the trigger of 2D and 2F.
Event 2A、2B、2C are used to trigger inter-frequency handover. The three
events are controlled by parameter InterHoTactic and will not be worked at
the same time.
All non-working carrier frequencies report Event 2E, indicating that radio
quality of all inter-frequency neighbor cells is poor and UE is at the edge of
3G coverage, then RNC may open inter-RAT measurement.

Inter-RAT handover means that an UE switches from one radio access system to
another, and specifically, from a UTRAN access system to a GERAN system. (If
an UE switches from a GERAN system to a UTRAN system, the GERAN system
policy is used.) Inter-RAT handover can be measurement-based handover
between systems or blind handover based on shared coverage or inclusion.
The prerequisite of measured-based Inter-RAT handover is that the UE
measures the quality of the Inter-RAT neighboring cells. In WCDMA system, for
Inter-RAT measurement in CELL_DCH state, the UE must enable compressed
mode for Inter-RAT measurement unless it has dual receivers. In addition,
regarding the influences of the compressed mode on the system and UE,
Inter-RAT measurement is enabled only when the current UTRAN system has poor
radio quality . When receiving Inter-RAT measurement result reported by the UE,
the RNC makes Inter-RAT handover decision and switches the UE to the target

49,162,206 0,102,255 Inter-RAT measurement is to measure the Inter-RAT cells. In the case of Inter-RAT
measurement, the measured quantity of the UTRAN network can be triggered based on the measured quantity of Ec/N0 or RSCP. The specific parameter used is controlled by the NonIntraMeasQuan parameter. The measured quantity of Inter-RAT measurement depends on the systems to be measured. For the GERAN, the measured quantity is RSSI. At present, Inter-RAT measurement supports only the handover modes reported through events.
ZTE UMTS support event 3A、3C for inter-RAT handover and uses 2D and 2F events as the criterions for evaluating the signal quality of the current frequency, If the UE reports a 2D event, that is, the current carrier is in poor signal quality, and no inter-frequency neighboring cells exist, or the UE reports a 2E event after inter-frequency measurement is started (that is, the signal quality of the measured inter-frequency neighboring cell is also poor), the RNC tries to initiate Inter-RAT blind handover or start Inter-RAT measurement 3A or 3C event to the UE based on the GSM neighboring cell cover.

Parameter name GSM Carrier RSSI Reporting Indicator
Abbreviated name GsmCarrRSSIInd
Description This parameter indicates whether the report of RSSI of the GSM
cells is requested or not. Since the measurement quantity of the GSM cell is only GSM Carrier RSSI, in inter-RAT measurement Event Reporting Criteria, there is no need to report this parameter when measuring the GSM cell and performing the Inter-RAT
handover. In the periodical reporting criteria, GSM carrier RSSI report is required.

Parameter name Cell individual offset(gsmRelation)
Abbreviated name CellIndivOffset(gsmRelation)
Description
An offset is allocated for each cell being monitored. The offset can be positive or negative. Before the UE judges whether an event occurs, adds the offset to the measurement result. If the PCPICH uses a positive offset, the UE sends the measurement report just like PCPICH is x dB better than the actual case. Or, if the PCPICH uses a negative offset, the PCPICH report is limited. When the cell individual offset is used, the corresponding cell is possibly (at least temporarily) the target cell of the handover or removed from the active set.

The handover parameters in TRUE network are default configuration except the
follow adjustment.
In the hot spot area TRUE TOWER, to make sure that users has good
experience (data rate>=400kbps) in HSPA coverage, the HSPA coverage
should not be too large. ZTE suggests to handover to GSM at the edge of
HSPA coverage. Some parameters are recommend to be changed:
