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 - E-CSCF <-> HSS for Emergency (3GPP TS 29.173)

Command	Direction	Description
LRR / LRA	E-CSCF -> HSS	LCS-Routing-Info - returns routing information for emergency location services.

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.
