RN-Radio Network

Consists of two components, namely Packet Control Function (PCF) and RadioResources Control (PRC). PCF main function is to establish, maintain and dissolve the relationship with the PDSN. PCF communicate with the PRC to request and set the radio channel for delivering packages to and from MS. PCF also responsible for collecting accounting and forward the information to the PDSN.



PRC supports authentication and authorization MS to get access to the radio. PRC also supports encryption for air interface MS-MSC (Mobile Switching Center) often called the interface between the BSC with the PSTN and data network (ISDN) through the gateway MSC (G-MSC).

Packet Data Serving Node (PDSN)
PDSN perform various functions. Its main function to make routing to IP packet networks, or HA. PDSN provide a dynamic IP address and keep the session Point-to-Point Protocol (PPP) to MS. PDSN start authentication, authorization and AAA to the accounting package for the session data. As the replies received PDSN parameters, profile customers that include the type of service and security.

Home Agent(HA)
HA role in the implementation of the Mobile IP protocol to continue with the package to the PDSN and vice versa. HA provides security by doing MS authentication through Mobile IP registration. HA also maintain relationships with AAA to receive information about customers.

Authentication, Authorization and Accounting (AAA)
AAA has a role that varies depending on the type of network where AAA connected. If the AAA server is connected to the service provider's network, the function is the main route authentication requests from the PDSN to the Home IP network, and authorize the response from the home IP network to PDSN. AAA also save accounting information from MS and provide the customer profile information and QoS for PDSN.

If the AAA server is connected to the home IP network, AAA do authentication and authorization for MS based on a request from the local AAA. If AAA connected to the broker network, he continues between the request and response service provider's home network and the IP network that does not have bilateral relations.

MSC (Mobile Switching Center)
Often called the interface between the BSC with the public voice (PSTN) and data network (ISDN) through the gateway MSC (G-MSC).

HLR (Home Local Register)
Work to save all the customer data such as IMSI, location data users, the Shared Secret Data (SSD) for all users, and other specific information for each autentifikasi users Center (AuC) for the storage Major Electronic Serial Number(ESN) for each user registered user.

Router
Work for packet data to and from the various elements CDMA2000 network. Router is responsible to send and receive package internal network or vice versa. To ensure security when related to the application data networks outside, then the required fire wall.
