Assignment Consider a 2G - GSM mobile phone which has been turned off for a while. The user turns it on and tries to make a phone call to another mobile phone in the same mobile operator's network which is also a 2G network. Write down ALL messaging between various components of the GSM architecture and the mobile phone being turned on until the call is established (so do not consider the other side of the phone call) in a timeline with appropriate messaging and names of the channels being used. When making a phone call assume that the user fails in the first 2 random- access trials and succeeds on the 3rd random-access trial.
