27-167 Cisco Prime Network 4.3.2 User Guide EDCS-1524415 Chapter 27 Managing Mobile Networks LTE Networks Figure 27-20 SaMOG Gateway Topology The SaMOG Gateway enhances the network services in the following ways: Provides seamless mobility between the 3GPP EPC network and WLANs for EPS (Evolved Packet System) services via the GTPv2-based S2a interface. Functions as a 3GPP Trusted WLAN Access Gateway (TWAG) as the Convergence Gateway (CGW) service. The CGW service terminates the S2a interface to the P-GW and acts as the default router for the WLAN UEs on its access link, and as a DHCP server for the UE. When the TWAN provides access to EPC for an UE, it forwards packets between the UE-TWAG point-to-point link and the S2a tunnel for that UE. The association in the TWAN between UE-TWAG point-to-point link and S2a tunnel is based on the UE MAC address. Functions as a 3GPP Trusted WLAN AAA Proxy (TWAP) as the Multi Radio Management Entity (MRME) service. The MRME service terminates the STa interface to the 3GPP AAA server and relays the AAA information between the WLAN IP access network and the AAA server, or AAA proxy in the case of roaming. It establishes the binding of UE subscription data (including IMSI) with UE MAC address on the WLAN Access Network. The function provides the TWAG with UE subscription data during initial attach or at UE subscription data modification.

27-168 Cisco Prime Network 4.3.2 User Guide EDCS-1524415 Chapter 27 Managing Mobile Networks LTE Networks SaMOG Service The SaMOG Gateway acts as the termination point of the WLAN access network. The SaMOG service enables the WLAN UEs in the trusted non-3GPP IP access network to connect to the EPC network via Wireless LAN Controllers (WLCs). During configuration, the SaMOG service gets associated with two services: the Convergence Gateway (CGW) service and the Multi Radio Mobility Entity (MRME) service. These collocated services combine to enable the SaMOG Gateway functionality. CGW Service The Convergence Gateway (CGW) service functions as a 3GPP Trusted WLAN Access Gateway (TWAG), terminating the S2a interface to the P-GW and acts as the default router for the WLAN UEs on its access link. The CGW service has the following key features and functions: Functions as a Local Mobility Anchor (LMA) towards the WLCs, which functions as a Mobile Access Gateway (MAG) with Proxy MIP capabilities per RFC 5213 and 3GPP TS 29.275 V11.5. Enables the S2a interface towards the P-GW for session establishment per 3GPP TS 29.274 V11.5. Routing of packets between the P-GW and the WLAN UEs via the Wireless LAN Controllers (WLCs). Support for PDN type IPv4. Interacts with the MRME service to provide user profile information to establish the GTP-variant S2a interface towards the P-GW per 3GPP TS 29.274. Provides a Generic Routing Encapsulation (GRE) data path towards the WLCs per RFCs 1701 and 1702 for tunneling of data towards the WLCs. Also follows RFC 5845 for exchanging GRE keys with WLC-based PMIP signaling. Receives and sends GTPU data packets towards the P-GW per 3GPP TS 29.281 V11.5. MRME Service The Multi Radio Mobility Entity (MRME) service functions as a 3GPP Trusted WLAN AAA Proxy (TWAP), terminating the STa interface to the 3GPP AAA server. The service relays the AAA information between the WLAN IP access network and the AAA server, or AAA proxy in the case of roaming. The MRME service has the following key features and functions: Relays the AAA information between the Wireless LAN Controllers (WLCs) and the 3GPP AAA server. Supports EAP-over-RADIUS between the SaMOG Gateway and the WLCs to authenticate the WLAN UEs per RFC 3579. Supports the Diameter-based STa interface between the 3GPP AAA server/proxy and the SaMOG Gateway per 3GPP TS 29.273 V11. Supports the exchange of EAP messages over the STa interface per RFC 4072. Functions as a RADIUS accounting proxy for WLC-initiated accounting messages. Supports RADIUS Dynamic Authorization Extensions per RFC 3576 to handle HSS/AAA-initiated detach and Diameter re-authorization procedures. Supports authentication between the WLAN UEs and the 3GPP AAA server using EAP-AKA, EAP-AKA, and EAP-SIM.
27-169 Cisco Prime Network 4.3.2 User Guide EDCS-1524415 Chapter 27 Managing Mobile Networks LTE Networks Supports static and dynamic P-GW selection after the authentication procedures. Supports PDN type IPv4. Maintains a username database to reuse existing resources when the CGW service receives PMIPv6 procedures initiated by the WLCs. Interacts with the CGW service to provide user profile information to establish the GTP-variant S2a interface towards the P-GW per 3GPP TS 29.274.

Scheduling 3GPP Inventory Retrieval Requests The 3GPP Inventory Management Web Services for Prime Network Integration Layer (PN-IL) retrieves the physical and logical inventory data from the Prime Network managed devices. For details on supported network elements, see Cisco Prime Network 4.3.2 Supported Cisco VNEs. For more details on the 3GPP inventory management and the web services, refer to the Cisco Prime OSS Integration Guide, 2.0. Prime Network allows you to schedule a web service operations for Prime Network Integration Layer to run immediately or at a later point in time. Using Prime Network - Web Service Scheduler option, you can do the following: Select the inventory request type based on which the inventory data will be retrieved from either all the supported devices or from the specified devices under Prime Network. Schedule the 3GPP inventory management web service operations to initiate the inventory request and executes it according to the specified schedule. To schedule web services: Step 1In the Vision client, Events client, or Administration client, choose Tools > Web Service Scheduler. Step 2In the Web Service Scheduler window, select General tab and select the inventory request type. Table 27-117 describes the details of the Web Service Scheduler - General tab.

Viewing Operator Policies, APN Remaps, and APN Profiles Operator policy provides mechanisms to fine tune the behavior of subsets of subscribers above and beyond the behaviors described in the user profile. It can also be used to control the behavior of visiting subscribers in roaming scenarios, enforcing roaming agreements, and providing a measure of local protection against foreign subscribers. An operator policy associates APNs, APN profiles, an APN remap table, and a call-control profile to ranges of International Mobile Subscriber Identities (IMSIs). These profiles and tables are created and defined within their own configuration modes to generate sets of rules and instructions that can be reused and assigned to multiple policies. In this manner, an operator policy manages the application of rules
