Answer Posted / vinit panchal
gsm can handle 18 to 20 calls at a time in a second where as a cdma can handle 30 to 32 call at a time in a second .
when capacity of call handling is increases more then it's range then bts will handle only those call which are in process and it will reject those calls which are remaining.
when call handling capability increases more then the it's range then bts will send a signal to msc(mobile switching center). msc is programmed by a particular software. controller is present in the msc it will read the signal which is sent by bts then it will send a new signal to bts in the form of msg. "network is busy " and bts will send us this signal to our mobile. whenever this things is happen the bts will send signal to msc and msc will rply.msg. is depends on the programming we can also use this type of msg. "out of coverage:, "the no is not available " etc... msg. depending on the programming ..........
