VectorCore HSS

A high-performance Home Subscriber Server (HSS), PCRF, HLR, UDM, UDR, and PCF for 3GPP 2G/3G, LTE/4G, 5GC, and IMS networks, written in Go.

Features

Multi-interface Diameter server - S6a, S6c, S13, Cx, Sh, Gx, Rx, SWx, SLh, Zh on a single TCP/SCTP listener
GSUP/HLR - Osmocom IPA+GSUP server (port 4222) for OsmoMSC/OsmoSGSN; handles SendAuthInfo, UpdateLocation, PurgeMS; generates 2G triplets and 3G quintuplets for CSFB voice and SGs SMS
SMS routing (S6c) - Send-Routing-Info-for-SM (SRI-SM) resolves MSISDN to serving MME for MT SMS delivery via SGd/T4; Report-SM-Delivery-Status (RSDS) stores Message Waiting Data on delivery failure; Alert-Service-Centre (ALSC) is HSS-initiated and fires automatically when the subscriber re-attaches; SMS-in-MME registration state (MME-Number-for-MT-SMS, MME-Registered-for-SMS) tracked per subscriber via ULR
5GC UDM, UDR, and PCF - N13, N10, N8, N15, and N7 support over a shared SBI listener; UDM, UDR, and PCF are co-located in one process with in-process data sharing; nudr-dr / N36 endpoints are exposed for internal service-to-service use
Milenage authentication - EUTRAN vector generation (AIR), EAP-AKA vector generation (SWx MAR), GBA vector generation (Zh MAR); custom c/r constant profiles per-AUC
Atomic SQN management - SELECT FOR UPDATE prevents SQN races during concurrent AIR from multiple MMEs
In-memory read cache - 60-second TTL cache on AUC and Subscriber hot paths
5G NSA support - Access-Restriction-Data bitmask per subscriber controls NR secondary RAT access
GeoRed - Active-active N-node geographic redundancy over HTTP/2 with batched event replication; replicates OAM changes and dynamic state (SQN, serving MME/SGSN, Gx sessions) across nodes
TAC database - GSMA IMEI Type Allocation Code database loaded into memory at startup; enriches EIR history with device make and model
OAM REST API - Full CRUD over all subscriber data; OpenAPI 3.1 spec with interactive docs at /api/v1/docs
Prometheus metrics - Diameter request counters and latency histograms at GET /metrics
Dual transport - TCP always on; SCTP optional (requires kernel SCTP module)
PostgreSQL + SQLite - Production on PostgreSQL; SQLite for testing
GORM AutoMigrate - Schema is created or updated on startup; safe to run against existing data
Structured logging - JSON via go.uber.org/zap

Diameter Interfaces

S6a - LTE HSS <-> MME (3GPP TS 29.272)

Command	Direction	Description
AIR / AIA	MME -> HSS	Authentication-Information - generates Milenage EUTRAN vectors (RAND, XRES, AUTN, KASME). Supports 1-5 vectors per request and SQN re-synchronisation via AUTS.
ULR / ULA	MME -> HSS	Update-Location - registers the serving MME; returns full Subscription-Data (UE-AMBR, NAM, MSISDN, APN-Configuration-Profile with per-APN QoS).
PUR / PUA	MME -> HSS	Purge-UE - clears the serving MME on UE detach.
NOR / NOA	MME -> HSS	Notify - handles flags-only UE state changes (e.g. UE reachability, MPS registration).
CLR / CLA	HSS -> MME	Cancel-Location - sent to the old MME when a subscriber re-attaches to a new one.
IDR / IDA	HSS -> MME	Insert-Subscriber-Data - pushes updated subscription data to the serving MME.
DSR / DSA	HSS -> MME	Delete-Subscriber-Data - instructs MME to remove subscription data.
RSR / RSA	HSS -> MME	Reset - instructs MME to re-authenticate all subscribers after a reset.

S13 - Equipment Identity Register (3GPP TS 29.272)

Command	Direction	Description
ECR / ECA	MME -> HSS	ME-Identity-Check - checks IMEI against the EIR table; returns WHITELISTED (0), BLACKLISTED (1), or GREYLISTED (2). Supports exact and regex match modes. IMSI/IMEI pairs are optionally logged to eir_history.

S6c - SMS Routing HSS <-> SMS-SC (3GPP TS 29.338)

Command	Direction	Description
SRI-SM / SRI-SMA	SMS-SC -> HSS	Send-Routing-Info-for-SM - looks up subscriber by MSISDN (or IMSI, BCD-encoded on the wire); returns IMSI, serving MME address and realm, and MME-Number-for-MT-SMS so the SMS-SC can route the MT SMS via SGd/T4. Returns MWD-Status flags if message waiting data is pending.
RSDS / RSDSA	SMS-SC -> HSS	Report-SM-Delivery-Status - on delivery failure (absent subscriber or memory-capacity exceeded) stores a Message Waiting Data record keyed to the SMS-SC; on successful delivery clears the MWD record. Supports MNRF and MCEF status flags per TS 29.338 §5.3.2.4.
ALSC / ALSCA	HSS -> SMS-SC	Alert-Service-Centre - HSS-initiated; sent to each SMS-SC with a pending MWD record when the subscriber re-attaches (triggered by ULR success). MWD is deleted only after the SMS-SC returns Result-Code 2001; if the peer is unreachable the MWD is left in place and retried on the next ULR.

The ULR handler on S6a detects SMS-in-MME capability from ULR-Flags and the MME-Number-for-MT-SMS AVP, stores the registration state on the subscriber record, and sets the MME-Registered-for-SMS bit in ULA-Flags. SRI-SM returns this MME number in the Serving-Node grouped AVP so the SMS-SC can route directly to the MME.

Cx - IMS HSS <-> CSCF (3GPP TS 29.228 / 29.229)

Command	Direction	Description
UAR / UAA	CSCF -> HSS	User-Authorization - checks if a public identity is allowed to register at the requesting CSCF.
SAR / SAA	CSCF -> HSS	Server-Assignment - records the S-CSCF serving a public identity; returns the IMS subscriber's Cx User-Data XML including IFC.
LIR / LIA	CSCF -> HSS	Location-Info - returns the S-CSCF name for a given public identity.
MAR / MAA	CSCF -> HSS	Multimedia-Authentication - generates SIP Digest or AKA authentication data.
RTR	HSS -> CSCF	Registration-Termination - forces de-registration of a public identity.
PPR	HSS -> CSCF	Push-Profile - pushes an updated IMS profile to the serving CSCF.

Sh - IMS HSS <-> Application Server (3GPP TS 29.328 / 29.329)

Command	Direction	Description
UDR / UDA	AS -> HSS	User-Data - returns Sh-Data XML (AVP 702) for a subscriber. Dynamically renders IMPU, IMPI, S-CSCF name, IMS user state, and IFC (IFC only returned for Data-Reference=13). Supports RepositoryData (AS-stored blob) and all standard Data-Reference values (0, 10-17).
PNR / PNA	HSS -> AS	Push-Notification - pushes updated subscriber data to the Application Server.

Gx - PCRF <-> PGW (3GPP TS 29.212)

Command	Direction	Description
CCR / CCA	PGW -> HSS	Credit-Control - handles session establishment (CCR-I), modification (CCR-U), and termination (CCR-T). Tracks active PGW sessions in serving_apn.
RAR / RAA	HSS -> PGW	Re-Auth - installs or removes dedicated bearers on an active Gx session; triggered by AAR/STR from the P-CSCF via Rx.

Rx - P-CSCF <-> PCRF (3GPP TS 29.214)

Command	Direction	Description
AAR / AAA	P-CSCF -> HSS	AA-Request - provisions QoS resources for a VoLTE media session; triggers a Gx RAR to the PGW to install a dedicated bearer.
STR / STA	P-CSCF -> HSS	Session-Termination - tears down the Rx session and triggers a Gx RAR to the PGW to remove the dedicated bearer.

SWx - AAA Server <-> HSS for non-3GPP WiFi (3GPP TS 29.273)

Command	Direction	Description
MAR / MAA	AAA -> HSS	Multimedia-Authentication - generates EAP-AKA vectors (RAND, XRES, AUTN, CK, IK) for non-3GPP WiFi authentication.
SAR / SAA	AAA -> HSS	Server-Assignment - returns Non-3GPP-User-Data (access allowed or barred based on subscriber status).
RTR	HSS -> AAA	Registration-Termination - de-registers a non-3GPP session.
PPR	HSS -> AAA	Push-Profile - pushes an updated non-3GPP access profile to the AAA server.

SLh - GMLC <-> HSS for Location Services (3GPP TS 29.173)

Command	Direction	Description
RIR / RIA	GMLC -> HSS	LCS-Routing-Info-Request/Answer (application ID `16777291`, command code `8388622`) returns serving-node routing information.

The GMLC uses the returned MME identity to route its SLg PLR to the MME. The HSS learns LTE MME name and realm from S6a ULR registration state. An attached subscriber returns MME-Name and MME-Realm; an existing subscriber without a usable serving node returns DIAMETER_ERROR_ABSENT_USER (4201), and an unknown subscriber returns DIAMETER_ERROR_USER_UNKNOWN (5001).

SLh authorizes the requesting GMLC by Origin-Realm, compared case insensitively with a trailing dot normalized. The HSS's own OriginRealm is always authorized. hss.SLhAuthorizedRealms adds specific external GMLC realms; an empty list authorizes no external realm. Unauthorized requests return DIAMETER_ERROR_UNAUTHORIZED_REQUESTING_NETWORK (5490). SLh normally uses SCTP; set hss.EnableSCTP: true (and provide kernel SCTP support) to enable the shared SCTP listener. TCP remains available for the other shared Diameter interfaces and lab interoperability.

Zh - BSF <-> HSS for GBA (3GPP TS 29.109)

Command	Direction	Description
MAR / MAA	BSF -> HSS	Multimedia-Authentication - generates GBA bootstrapping vectors for Generic Bootstrapping Architecture.

GSUP / HLR Interface

The GSUP server (port 4222 by default) implements the Osmocom IPA+GSUP protocol for 2G/3G circuit-switched authentication. It is used by OsmoMSC, OsmoSGSN, and OsmoSTP for CSFB voice and SGs SMS handling.

Message	Direction	Description
SendAuthInfo	MSC/SGSN -> HSS	Generates 2G triplets (RAND, SRES, Kc) or 3G quintuplets (RAND, XRES, CK, IK, AUTN) from Milenage.
UpdateLocation	MSC/SGSN -> HSS	Registers the serving MSC or SGSN; returns subscriber data.
PurgeMS	MSC/SGSN -> HSS	Clears the serving MSC/SGSN on detach.

Geographic Redundancy (GeoRed)

VectorCore HSS supports active-active N-node geographic redundancy. Each node replicates changes to its peers over HTTP/2 using batched event streams.

Two replication tracks are supported:

OAM sync - subscriber, AUC, APN, IMS subscriber, and EIR record changes
State sync - SQN increments, serving MME/SGSN assignments, Gx sessions

Events are batched by count (default 500) or age (default 10 ms) and delivered to each peer with bearer token authentication. Nodes are symmetric - any node can accept writes and will replicate to all others.

Roaming Control

Roaming is enforced at the Diameter layer on both AIR and ULR. When a subscriber attaches via a visited PLMN the HSS evaluates the following rules in order:

Home network - always allowed (visited PLMN matches home MCC/MNC).
Subscriber roaming switch - if roaming_enabled = false on the subscriber record the attach is rejected with ROAMING_NOT_ALLOWED.
Network rule - the visited MCC/MNC is looked up in roaming_rules. If a matching rule exists its allow flag is applied.
Undefined networks - if no rule matches, the roaming.allow_undefined_networks config flag controls whether the attach is permitted (default: true).

Roaming rules are managed via the OAM REST API (/api/v1/roaming_rules).

Config flag:

roaming:
  allow_undefined_networks: true   # allow roaming on networks with no explicit rule

OAM REST API

Served on port 8080 (configurable). Interactive documentation at http://<host>:8080/api/v1/docs.
