Chapter 1 - System Description The BreezeCOMPACT Solution
Following is a description of each of these working modes:
1.2.2.1 External ASN-GW
The ASN-GW is a separate entity (centralized architecture) that communicates with the BTS over R6
interface. Service components (Service Profiles and Service Flows) are configured in the external
ASN-GW. MS authentication and services provisioning are managed by a centralized AAA server, based
on user credentials (user name and password).
1.2.2.2 Embedded ASN-GW Local Authentication
The ASN-GW functionality resides in the BTS (distributed architecture). Service components (Service
Profiles and Service Flows) are configured in the internal ASN-GW of each BTS. MSs list and services
provisioning including authentication are managed locally by the internal ASN-GW (AAA server not
needed), based on the SU MAC address.
1.2.2.3 Embedded ASN-GW Centralized Authentication
The ASN-GW functionality resides in the BTS (distributed architecture). Service components (Service
Profiles and Service Flows) are configured locally in the BTS. MS authentication and service provisioning
are managed centrally by an external AAA server, based on user credentials (user name and password).
1.2.3 System Topologies
BreezeCOMPACT supports different system topologies:
 One Sector, One Carrier
 One Sector, Dual Carrier
 Two Sector, Two Carriers (One Carrier per Sector)
Following is a description of each of these topologies:
1.2.3.1 One Sector, One Carrier
This is the basic configuration based on a single BS, supporting a single 4x4 sector with a bandwidth of
5, 7, or 10 MHz.
INFORMATION
