2.1 Position of the ePico3801 on the Network of the uBro
Solution
The ePico3801 is used as the radio access device in the uBro solution.
The uBro solution adds the ePico3801, Access Gateway (AG), AP Home Register (AHR), and
AP Manager to the existing UMTS network. The AG is responsible for controlling and managing
ePico3801s. It also provides routing towards the UMTS core network. The ePico3801 is
connected to the enterprise LAN or modem, the enterprise LAN or modem is connected to the
public IP network, and the public IP network is connected to the AG. In this way, the ePico3801
can communicate with the AG, which connects the ePico3801 to the UMTS core network. The
standard Uu interface is used between the ePico3801 and the UE to ensure compatibility with
existing commercial terminals.
shows the position of the ePico3801 on the network
of the uBro solution.

The functions of the ePico3801 are equivalent to the functions of the
NodeB plus some functions of the RNC. It serves as the UMTS radio
access device, performing radio modulation and demodulation, radio
resource management, and power control.
AG
Used as the core network device in the uBro solution, the AG
performs the following functions:
l
Forwarding signaling messages on the control plane and data on
the user plane between the ePico3801 and the UMTS core network
l
Controlling and managing links for the ePico3801
