UA-UIMS
(UANGEL-Unified IMS)
The IMS (IP Multimedia Subsystem) is a required network node to provide the VoLTE (Voice over LTE) service on an LTE network. The UA-UIMS loads major IMS nodes in a virtualized hardware environment, and is a cost-effective IMS solution that is appropriate for small-size mobile communication networks and special mobile networks.
Key functions
| CSCF (Call Session Control Function) | SIP-based call processing, terminal number identification, and QoS management |
|---|---|
| TAS (Telephony Application Server) | Additional call service information management and additional service call processing control |
| MRF (Media Resource Function) | Media resources processing (call mixing, DTMF tone extraction, information broadcasting sending, etc.) |
| IBCF (Interconnection Boarder Control Function) | Interfacing other vendors IMS/LTE network |
| MGCF (Media Gateway Control Function) | MGW control to interface the line exchange network (PSTN, PLMN) |
| Integrated OAM | Managing the integrated operation of UA-UIMS nodes |
Key features
- Providing the interface environment based on global standards such as 3GPP, ETSI, and IETF
- Mounting the IMS function on virtualization-based single hardware (P/S/I-CSCF, TAS, MRF, IBCF, MGCF)
- Only necessary nodes can be configured (plug-in type), according to the service provider’s request.
- Providing a convenient UX with integrated OAM.
