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.

Intra-Frequency Handover Strategy:1A

As can be calculated from the above formula, you can increase the probability of

triggering Event 1A by either increasing R1a (Event 1A meets the reporting range

conditions) or decreasing H1a (Decision hysteresis range); otherwise, you can

reduce the probability of triggering Event 1A.

Event 1A supports period-based report, that is, once Event 1A meets the

reporting range of quality standards, the UE will report Event 1A periodically

(EvtRptInterval) until this event does not meet reporting conditions or the

reporting times reach the maximum allowed times (EvtRptAmount).

There is restriction over the size of active set, so Event 1A will not be reported

once the number of cells in the active set reaches certain threshold

(RptDeactThr).

Intra-Frequency Handover Strategy:1D

Event 1D indicates the quality of certain cell within or outside current active set is

better than the best cell in current active set, that is, the best cell changes in the active

set. The following can be triggered upon the receipt of Event 1D:

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).

Swap a cell into or out of the active set (the cell outside the active set reports

Event 1D but the number of links in the active set reaches the maximum).

The serving cell changes (for HS-DSCH/E-DCH).

Intra-Frequency Handover Strategy:Handling of Over 32 Adjacent Cells

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

geographical location of adjacent cell).

Intra-Frequency Handover Strategy:Handling of Over 32 Adjacent Cells

The graph shows the cell priority configuration based on the geographical location of adjacent cells.

Take the configuration of cells adjacent to the innermost gray cell as an example: there are three

layers of adjacent cells surrounding the gray cell, and they are differentiated from one another with

yellow (0: Top priority), blue (1: Medium priority) and red (2: Low priority)

The principle for inter-freq neighboring cells and inter-rat neighboring cells are same.

Intra-Frequency Handover: Detected set Handover

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

frequency”, that is, to only report the monitored set instead of detected set.

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

carried in the measurement results.

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

cell of the GERAN system specified in the measurement result.

Inter-RAT Handover Strategy:Inter-RAT Measurement

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.
