What is IMS interface?

Rx interface is Bridge between IMS Network & Packet Core . The Rx Interface is used between the P-CSCF and the PCRF allowing the request of an appropriate policy for a session for setting up Incoming & Outgoing Voice call .

Which interface is based on AAA protocol in LTE?

Diameter is a next-generation industry-standard protocol used to exchange authentication, authorization and accounting (AAA) information in Long-Term Evolution (LTE) and IP Multimedia Systems (IMS) networks.

What is P-CSCF in LTE?

A Proxy-CSCF (P-CSCF) is a SIP proxy that is the first point of contact for user equipment in an mobile network All SIP traffic to and from the user equipment must go through the P-CSCF.

What does S CSCF stand for?

Acronym. Definition. S-CSCF. Serving Call Session Control Function.

What is MB interface?

The 3GPP has defined the Mb interface as the bearer traffic terminated on the MRF, or more specifically the MRFP. Bearer traffic includes the growing volume of Real Time Protocol (RTP) packets, along with associated Real Time Control Protocol (RTCP) information in the bearer plane.

What is UT interface?

The Ut interface provides a user’s device with the ability to manipulate a configuration document. This document may contain user specific service settings such as privacy setting, communication barring and forwarding rules.

What is Impu and Impi?

IP Multimedia Private Identity (IMPI): IMPI is a global identity allocated by the home network. IMPI contains home operator’s domain information. Home operator’s domain name. IP Multimedia Public Identity (IMPU): IMPU acts like a telephone number. It can either be a SIP URI (sip: @ : ) or a tel URI.

What is IMS Signalling in LTE?

3.2. To support telephone signaling between the LTE network and telephone networks, the IMS uses SIP (Session Initiation Protocol). SIP is a standard protocol for establishing voice calls over IP networks. The code is open, and uses the ‘request-response’ model to allow communication sessions.

How do I test S6 interfaces in LTE networks?

Test MME and SGSN S6 interfaces in LTE networks with our HSS Server Emulator. Use the S6 Interface application on our SGSN and MME simulator nodes to test the capacity and performance of an HSS. Test VoLTE and PCC interactions by using the S6 Interface Application with other dsTest Interface Applications such as Gx, Rx, Ro, and Rf.

What is the difference between S6A and S6D in LTE?

The s6a interface is between MME and HSS in the LTE network and s6d is between SGSN and HSS. Both provide messages and procedures for the phone to attach for data. MME is the visiting node in the 4G network.

What is S6C interface in LTE?

S6c interface is used for mobility related authentications. It takes care of transport of commands to retrieve and to store mobility parameters. This LTE interface lies between HSS and SGSN (i.e. Serving GPRS Support Node). It is similar to S6a interface.

What is voice over LTE (VoLTE)?

What is Voice over LTE (VoLTE)? Outlined in GSMA standards, Voice over Long Term Evolution (Voice over LTE or VoLTE) is the practice of packetizing voice over the Internet Protocol (VoIP) and transporting both the signaling and media components over a 4G LTE packet switched (PS) data path.
