Network Element of Wireless Internet Service
Wireless internet service includes CDMA and GSM platforms and its next generation network e.g. 3G, 4G and EVDO platforms. In terms of CDMA platform, there are many network elements of wireless internet service on the CDMA platform which involve on the data service call flow such AAA (Authentication, Authorization, and Accounting), Public Data Serving Node (PDSN), Home Local Register (HLR) and charging system
Wireless internet service call flow on Radio Frequency level
Mobile internet service session which comes from modem or mobile phone is the first initialization of the wireless internet service call flow. Radio Frequency will reserve the resource for this session if any resource is available. I case, radio frequency resource is full capacity then network busy notification will be sent to mobile internet service session
Wireless internet service call flow on Public Data Serving Node (PDSN)
Public Data Serving Node PDSN will process the entire of wireless internet service call flow. Public Data Serving Node PDSN will communicate with the Base Station Controller through the BSC PCF address (interface A10/A11). Public Data Serving Node (PDSN) connects to the AAA (Authentication, Authorization, and Accounting) servers, allocating IP address for the subscriber, maintaining the session including disconnect the session. Session which comes from BSC will be forwarded by PDSN to AAA server for authentication process at the first stage. While authentication process is pass, PDSN will allocate a IP address for the subscriber.
Wireless Internet Service Call flow on AAA (Authentication, Authorization, and Accounting)
Telecommunication companies could implement AAA (Authentication, Authorization, and Accounting) into two stages where authentication and accounting call flow could land into different network element. This mechanism has many benefits and can be implemented for many purpose such as accounting forwarding, proxy accounting etc. Authentication process will identify several of authentication information while session arrives on authentication server such as username, password, domain and IMSI (International Mobile Subscriber Identification). Authentication will acknowledge the authentication process if the session meets the requirement (username, password, domain and IMSI is valid). In case one or more of authentication information is not passed then authentication service will reject the session
Accounting process will be executed by charging system if telecommunication companies divide AAA (Authentication, Authorization, and Accounting) process into two stages
