EPC Deployment key NEs listed - MME: All the new MME should support CSFB and select a MSC in the Pool base on IMSI-Hash. UGW: Integrated S-GW and P-GW into one device. HSS/HLR: Support 2G/3G/4G subscription data. Convergent HSS for 2G/3G/4G recommended to get a simple user data management. eNodeB: Support CSFB function and R8 redirection fallback mechanism in blind mode at least. Provision: Support sending data to HSS or HLR based on the user’s type. If the user is 4G, the data should send to HSS and STP with FNR. if the user is 2G/3G ,the data should send to HLR; Delete the 3G /2G data in HLR when user upgrade to 4G in HSS
A Signal Transfer Point (STP) is a node in an SS7 network that routes signaling messages based on their destination point code in the SS7 network. It works as a router that relays SS7 messages between signaling end-points and other signaling transfer points (STPs). Typical SEPs include service switching points and service control points. The STP is connected to adjacent SEPs and STPs via signaling links.
A Diameter Routing Agent (DRA) is an application with all functionalities of Diameter Relay Agents along with some additional functionalities such as load balancing, routing diameter traffic based on any field, routing Diameter messages to a specific node, divide traffic with various policies. It is a functional element in a 3G or 4G (such as LTE) network that provides real-time routing capabilities to ensure that messages are routed among the correct elements in a network.
The mSwitch™ SLR3200 (HLR / HSS / 5G UDM) stores and manages identities, authentication data, subscription information, and location information about subscribers. In addition, the mSwitch HSS verifies mobile terminals when mobile terminals attempt to connect to networks.
With 15 years of core network technology experience, Genew mSwitch IMS system has been deployed
many networks for a great number of operators around the world, serving millions of people.
