What is Bearer Independent Core Network?
GSM networks share a common core with UMTS networks. A wider variety of bearers must be made available in the core and radio access network to make the new services available for subscribers. Today’s exchanges and MSCs are optimised for voice transport.
What is Mgw in UMTS?
Media Gateway (MGW) interface; Stage 3.
What is bearer control?
The Bearer-Independent Call Control (BICC) is a signaling protocol based on N-ISUP that is used for supporting narrowband Integrated Services Digital Network (ISDN) service over a broadband backbone network. BICC is designed to interwork with existing transport technologies. BICC is specified in ITU-T recommendation Q.
What is the function of bearer?
In telecommunications, Bearer Service or data service is a service that allows transmission of information signals between network interfaces. These services give the subscriber the capacity required to transmit appropriate signals between certain access points, i.e. user network interfaces.
What is ISUP in telecom?
The Integrated Services Digital Network User Part (ISUP) is used for establishment of wired connections between exchanges. ISUP is the protocol used to support the signaling necessary to provide voice and non-voice services in telephone communications.
What is the interface between RNC and MGW media gateway?
The RNC carries out radio resource management, some mobility management functions and encrypts data before it is sent to and from the mobile. The RNC connects to the circuit switched core network through the media gateway (MGW) and to the SGSN (Serving GPRS Support Node) in the packet switched core network.
What is the core network of UMTS?
UMTS Core Network Architecture. As shown in Figure 4.1, the basic core network architecture for UMTS can be seen as a combination of GSM network subsystem (NSS) and GPRS backbone.
What is bearer network?
In a mobile network using the Long Term Evolution (LTE) architecture, bearers are the tunnels used to connect the user equipment to Packet Data Networks (PDNs) such as the Internet. In practice, bearers are concatenated tunnels that connect the user equipment to the PDN through the Packet Data Network Gateway (P-GW).
What is bearer circuit?
A bearer circuits is one which transports one or more smaller capacity circuits or channels. In this case a 100mbits bearer is being used to transport a 20 Mbits circuit.
Is SS7 used in LTE?
SS7 and Diameter Signaling While SS7 was the foundation for signaling in 2G/3G circuit switch networks, Diameter has been introduced for 4G LTE and VoLTE packet networks and IP Multimedia Subsystem (IMS) based systems, and is key to enabling new revenue-generating IP services.
What is ISUP call flow?
The ISDN (Integrated Services Digital Network) User Part or ISUP is part of Signaling System No. 7 (SS7), which is used to set up telephone calls in the public switched telephone network (PSTN). It is specified by the ITU-T as part of the Q. 76x series.
What is IUB interface in telecom?
The Iu interface is an external interface that connects the RNC to the Core Network (CN). The Uu is also external, connecting Node B with the User Equipment (UE). The Iub is an internal interface connecting the RNC with Node B.
