Core Network Solutions

Equipment Identity Register (EIR)

  • High-capacity, multi-protocol, advanced signaling solution
  • Full compliance with international standards

PROTEI EIR enables network operators to enter the IMEI of stolen handsets into a “blacklist”, thus preventing them from being registered on the network.

PROTEI EIR provides automatic device detection functionality required for identification of changes of subscriber’s device. Every change of subscriber’s device will be detected by PROTEI EIR. Detection is based on MAP procedures (MAP-CHECK-IMEI) in full accordance with international standards. The change of subscriber’s device leads to the change IMEI-connected with MSISDN by comparison received IMEI with saved one. PROTEI EIR can detect changes calling the notice of external system.
PROTEI EIR is based on PROTEI xVLR solution that is “umbrella” platform providing the ability to process, store and transmit to the external applications location information regarding subscribers of mobile networks, switching elements may transfer. The platform is able to process information that is available through core network vendors’ proprietary features or using standard MAP capabilities. Collected data may be efficiently used for such services as geographically targeted SMS campaigns, loyalty services and many others.

Home Location Register (HLR/HSS)

  • CORE element in any carrier network
  • Full compliance with 3GPP standards

PROTEI Home Location Register is a cost-effective, high performance and scalable solution to suit both - new and existing mobile operators, MVNO, service- and content providers. PROTEI HLR scalable architecture and flexible throughput licensing enables an Operator or provider to select a solution that not only mirrors the revenue stream of today, but can be used to meet operator tomorrow's needs. 

PROTEI HLR contains the permanent subscriber data register with entries for each and every subscriber within a mobile network. It contains static and permanent information about a subscriber. The HLR works as the central location to route calls within the respective mobile operator’s network. Most of the administrative activities regarding the subscribers are controlled and centralized around the HLR. The Authentication Centre (AuC) is integrated to PROTEI HLR to provide more efficient and effective mobile network design. Thus, PROTEI HLR contains authentication information as well. It also forwards the charging information to the billing center. 

PROTEI HLR/HSS is developed in strict accordance with ETSI 3GPP standards that gives the Operator unique possibility to obtain a long-term storage of information about its subscribers containing pertinent user information, including address, account status, and preferences. 

Key Benefits

  • Centralized database with information about each SIM-card
  • Can be configured as a separated node in mobile network
  • Horizontally scalable
  • Single database remains for several HLRs
  • Registration of roaming subscribers data, including TMSI and VLR
  • Storage all information about services granted or requested by subscriber
  • SNMP and alarm indication support

STP (Signaling Transfer Point)

  • Powerful routing, screening and SS7 message manipulation solution
  • Carrier grade technology packed with feature rich capabilities 

PROTEI STP is highly effective solution for signaling messages routing. All tasks connected with extra flexible signaling traffic routing, special routing for particular messages, necessity to connect more than one roaming provider can be solved using by PROTEI STP. It’s also a proven solution for deploying active steering platform or SMS Firewall. 

PROTEI STP provides a comprehensive future proof STP supporting legacy SS7 TDM and Next Generation IP SIGTRAN. A mature, proven, carrier grade technology packed with feature rich capabilities and at reasonable cost.

Out of the box PROTEI STP offers a range of benefits and features including flexible routing of particular SS7 messages, solving routing conflicts due to multi-system integrations and thus, rapid service enablement.

As well, PROTEI STP is the suitable choice to lower CAPEX as it provides a flexible pricing model to match budget expectations, scale of deployment and future growth requirements.
