Products

UDM

UDM(Unified Data Management) provides UE authentication, registration/mobility management, subscription management, SMS management.

    • Provide Nudm service-based interface to NF Consumers(e.g. AMF, SMF, SMSF, etc.)
    • SIDF(Subscriber Identity De-concealing Function)
    • ARPF(Authentication Credential Repository and Processing Function)
    • Support SMS over NAS
    • Legacy HLR/LTE-HSS integrated system available
    • Provide Multi-Vendor Interoperability through compliance with 3GPP standards

UDR

UDR(Unified Data Repository) allows 5G NF(Network Function) to store and retrieve data. Storable data includes subscriber data, policy data, structured data, application data, etc.

    • Resource URI and related JSON format create/retrieve/update/delete
    • 3GPP SBI compliant, Data create/retrieve/update/delete upon NF request
    • NF authentication, Control resource access
    • Prevent data inconsistency caused by redundant data integrate
    • Reduce the total data size
    • Client specialized data storage and inquiry

SEPP

SEPP(Security Edge Protection Proxy) is a proxy that provides message filtering and policy and topology hiding at the Inter-PLMN (Public Land Mobile Network) Control Plan Interface among 5G Core network functions.

    • N32c Interface (N32 Handshake Procedure)
    • N32f Interface (Protected Message Forwarding Procedure)
    • Manage TLS Connection, SBI(Service-based Interface)
    • Provide security and proxy for Inter-PLMN roaming message process
    • Provide client specialized feature including 3GPP standard feature

NRF

NRF(Network Repository Function) is a NF(Network Function) Service Framework component system, defined by 3GPP 5G standard. This infra system supports interconnection between 5G Core NFs by monitoring dynamically changed 5G Core NF service status and managing interworking information(e.g. IP address, FQDN, etc.)

    • Manage and provide NF instance information
    • Provide access token with valid authentication/authorization for requested service
    • Manage NF profile information
    • Manage NF status based on message received
    • Provide optimal interworking NF information through NF RTT monitoring
    • Secure integrity of NF instance information through MANO interworking
    • Support NF load balancing selection

UPF

UPF(User Plane Function) connects UE and external data network in 5G core network. Interworking with SMF(Session Management Function), UPF manages PDU(Packet Data Unit) session and routes packet between UE and external data network in order to transmit.

    • PFCP-based SMF Interworking
    • Mobility Anchor Point (Intra-RAT, Inter-RAT, N3 End marker)
    • GTP Packet Processing
    • Private 5G specialized system Core Node integrated/separated architecture support
    • High-speed packet processing using DPDK (Data Plane Development Kit)
    • Various virtualized environment (KVM, Bare-Metal, Openstack) support

HLR/HSS

HLR(Home Location Register)/HSS(Home Subscriber Server) is a fundamental system in 3G and 4G newtork which in real time manages mobile subscriber information: location information, authentication information, service information, permission, add-on information, etc. Interworking with MSC/VLR, SGSN, MME, SMSC, OTA, Service Node, it serves outgoing/incoming, authentication, short message, packet transmit, location information, IN(Intelligent Network), and AUC which authenticates 3G/4G subscriber as well.

    • COTS Hardware and various OS environment software available
    • Subscriber authentication integrate/separate available
    • Multi-Vendor Interoperability
    • Complete High-Availability and Geo-Redundancy

GLR

Telcoware GLR(Gateway Location Register) has both features of HLR/VLR, a fundamental element of mobile telecommunication network, and protocol conversion. GLR acts as a gateway to support roaming service among service providers using different MAP(Mobile Application Part) protocol(GSM, ANSI-41, PDC, etc.)

    • MAP protocol (ANSI-41, GSM, PDC, WCDMA) conversion
    • Network configuration for CDMA <-> CDMA, CDMA <-> GSM, CDMA <-> WCDMA
    • Virtual HLR (Home Location Register) for the roamed network
    • Automatic location registration enables one system to interwork with multiple networks.

5G-EIR

5G-EIR(Equipment Identity Register) is a network function that checks PEI(Permanent Equipment Identifier) status such as PEI blacklist status, etc.

    • Device authentication, Notify 5G PEI device capacity information to UDM(Unified Data Management)
    • Process arbitrary device change request
    • Process SBI(Service-based Interface)
    • Authenticate to prevent unauthorized device use based on PEI status on 5G Core
    • Serve arbitrary device change process

NPDB

NPDB(Number Portability DataBase) is a database system that includes information necessary for supporting number portability. (Number portability is a feature that allows a subscriber to move to another service provider while retaining his/her number.)

    • Manage NPDB subscriber data(subscriber number, routing number, NPDB status, etc.)
    • Download, upload, audit, and real time search for port-in number data.

Telcobase™

Telcobase™, a MMDBMS(Main Memory Database Management System) software, uses memory as data storage and manages the memory. While original DBMS saves DB in disk and uses memory as a minor device, MMDBMS resides DB in main memory and uses disk as a backup device.
