CBS Event triggered broadcast
Description
Cell Broadcast Service (CBS) enables broadcast of information,
E.g. traffic news or warnings, to devices in a pre-defined area.
Broadcasting provides an efficient way to reach a large population of devices with a message
Benefit
Event triggered broadcast provides a way to reduce impact of CBS on the device battery lifetime to virtually zero
Allows
to reduce time to deliver an emergency messages to below 8 sec allowing one repeated transmission
Commercial in confidence | 2012-11-17 | Page 61 (106)
CBS Event triggered broadcast Sending a message
By reading system information the UE finds out how and when to decode the CBS messages
With event triggered broadcast the following happens when a message is sent
The system information broadcast (SIB) is updated signaling that
the CTCH is active
The devices are notified that the SIB is updated
The message is repeated on the CTCH a configurable number of times
When the message is sent, the CTCH is turned off and the SIB returns to its original state

Performance of 4-way diversity
The number of receiver antennas is of fundamental importance for the capacity of a CDMA radio system
Theoretically the capacity scales with the number of antennas
This is since lower receiver power is needed to achieve a certain signal to interference ratio
With Interference Suppression (FAJ 121 1714) gains may be even larger
Since lower received power is needed, the coverage is also enhanced

Description
The new GPEH Capacity Increase feature is based on and fully compatible with the existing GPEH feature, but provides support for far higher level of event intensity and recording capability as well as reduced ROP periodicity to 1 minute ROP periods, instead of 15 minutes ROP periods
Benefits
More efficient and much faster network analysis, satisfying the need to both existing, as well as creating a solid ground for future advanced event based applications, like:
Boosted GPEH capacity satisfies future data demand
Frequent data provisioning with smaller files every minute
Flexible counter resolution possible for EBS based counters
