I am New to this telecom field. Can u please help me out in explaining how the announcements like “NETWORK BUSY”,”OUT OF COVERAGE AREA”,”SWITCHED OFF”,”SUBSCRIBERS NOT REACHABLE” announcements are coming
it will be of great help if u guys elaborate it more technically31st August 2004 at 02:23 #39744MisaGuest
I think the announcement is different from operator to operator. And you should give us more details in what case the announcements are coming. For example, if you make a outgoing call (MOC) and you get the announcement “SUBSCRIBERS NOT REACHABLE” => MS may be in implicit detached status. If “SWITCHED OFF” => MS in explicit detached status. Other announcements (“NETWORK BUSY”,”OUT OF COVERAGE AREA”) in what circumstance?31st August 2004 at 07:42 #39745akshayGuest
Assume this situation. I am in Bangalore and if I am calling to a person in New Delhi and if I get the below mentioned announcements like “NETWORK BUSY”, “OUT OF COVERAGE AREA” Also please explain what is implicit detached status and explicit detached status.7th September 2004 at 07:21 #39746MisaGuest
In order to know exactly what happens with these announcements, we should know what system u are using. Generally, 1 announcement will represent for 1 or some errors in the system. In most case, “NETWORK BUSY” => there is not enough resource (such as TCH, SDCCH) for the calling subscriber to make a call; “OUT OF COVERAGE AREA” => the called subscriber is out of service (may be turned off or out of coverage area).
implicit detached = subscriber is out of service due to lost of radio signal or empty battery
explicit detached = subscriber turn off by power button on the phone.
