Handover
General Description
When the signal transmission quality becomes inferior, a PS re-originates a call automatically and seizes anoth-
er radio channel, making the WCS handover the call to another CS to maintain the speech quality.
Configuration Application
Integrated Type and Adjunct Type
Operating Procedure
No manual operation is required. The PS sends the Handover request to the WCS automatically.
Service Conditions
1. This feature is activated when a PS is engaged in communication.
2. The communication may be interrupted during operation of this feature. The interruption is usually within
a second, to a maximum of ten seconds.
3. This feature is also available when a PS user moves to the far end of the radio zone and encounters inferior
transmission quality. In this case, the PS searches for the radio zone of stronger electric field. If the radio
zone is found, Handover is activated and the conversation is continued in that zone. If there is no idle chan-
nel in the new radio zone, the conversation is continued in the current zone until the communication be-
comes unavailable. Then, Automatic Release - Out of Cell Calls is activated.
4. PS Authorization is activated every time this feature is activated.
