Functionality
- Support of a large number of signalling protocols and their extensions that allows working with VoIP-networks and maintaining interoperability with PSTN;
- Powerful system of data collection and analysis for monitoring the quality of service (QoS) according to various parameters: CallQoS (ASR, CAPS, SC, ACD, PDD, SCD), VoiceQoS (R-Factor, PESQ, bandwidth, loss);
- Intelligent routing of calls according to various parameters, including SLA and the traffic intensity of directions;
- Ability to query external systems for routing parameters, in particular over protocol RADIUS;
- Ability to perform routing according to various parameters, including e-call flag;
- Convenient licensing mechanism based on the number of simultaneous calls;
- Ability to modify the numbers of calling and called subscribers and to establish connection using the modified numbers;
- Ability to flexibly adapt the format of data included in records about provided services (Call Detail Record) according to the requirements of the operator and service providers;
- Ability to gather statistics on the provided services;
Interaction with Operator infrastructure
PROTEI GMSC can be connected to other nodes of the Operator by via Ethernet interfaces or via E1 trunks. Transmission of TCAP transactions can be done by means of protocol stack Ethernet/SIGTRAN/M3UA or MTP/SCCP/TCAP.
Management of voice calls is done by means of protocol stack SIP(SIP-I/SIP-T). Protocol CAP of version v1.3 is supported.
Administration and maintenance
PROTEI GMSC supports remote administration and control through a modem connection or a Telnet session over secure connection TCP/IP/SSH. Also a WEB-based technical maintenance system can be used.
SNMP protocol is supported for the purposes of emergency indication and collection of statistics information.
Scalability, performance and licensing of the system
PROTEI GMSC is an operator-class solution that supports horizontal scaling according to growing demands of the Operator. Modular structure of the system ensures high reliability and efficient scalability according to growing demands of the Operator and increased popularity of services.
If system load exceeds the capacity (specific productivity) of one module, several modules are included in the system configuration in load sharing mode.
