GE863 proceeds to the authentication with the parameters specified par. 5.1.2.1 and par. 5.1.2.2. note that activating a context implies getting an ip address from the network and this will be maintained throughout the session. the response code to the at#gprs=1 command reports the ip address obtained from the network, allowing the user to report it to his server or application.
