2.1.1 Smart LTE Handover

Feature Component ID:

Summary: This feature introduces outgoing LTE PS handover.

Benefits for the Customer:

seamless handover experience for the end users.

Functional Description:

compressed mode measurements indicate that LTE coverage is available.

Following events can trigger HSDPA compressed mode measurements for LTE:

1) Cell_DCH to Cell_FACH, Cell_PCH or URA_PCH selection

2) HSDPA reconfiguration to tra

cause reconfiguration to DCH 0/0.

3) CS call release

4) Periodic trigger, operator definable timer

In uplink DCH is used during compressed mode. HSUPA compressed mode is supported with

RAN1668.

RAN2980: Measurement based LTE layering uses compressed mode measurements for confirming

LTE layer availability before redirection is started.

Interdependencies between Features:

For HSUPA compressed mode measurements RAN1668 is required.

When layer specific absolute priority information is provided in the system information broadcast,

UE periodically measures higher priority layers. UE measurements are applicable when the UE is in

idle mode, Cell_PCH, or URA_PCH state. Also lower and equal priority layers ar

radio conditions in the camped frequency fall below search thresholds.

Based on measurements, UE performs priority based cell reselection using both coverage and

quality thresholds broadcast in SIB 19.

For WCDMA and GSM priority

In addition to the priority number for the layer, signal strength and quality thresholds are tools for

adjusting the cell re-selections. Frequency band prioritization can be adjusted with thresho

e.g. prefer 900MHz for cell edge UEs and 2100MHz for close by UEs. UEs above certain threshold

move to higher priority layer, whereas cell edge UEs prefer low priority layer as thresholds are not

met.
