Which application protocol is used between RNC in UMTS?

Radio Access Network Application Part
ALCAP is carried over Iub and Iu-CS interfaces. Signalling protocol responsible for communication between RNC and the core network is called RANAP (Radio Access Network Application Part), and is carried over Iu interface.

What is SRNS relocation in UMTS?

SRNS relocation is a procedure used during mobility scenarios when Control of the Serving Radio Network Subsystem (SRNS) is changed to another Radio Network Subsystem (RNS) Radio Network Subsystem (RNS): The RNS controls the allocation and release of radio resources to establish a connection between a UE and the UTRAN.

What is Iups interface?

Iu-PS is the interface between the UMTS RNC (Radio Network Controller) and the SGSN (Serving GPRS Support Node) supporting UMTS integrated services such as multimedia and global roaming to mobile users. The dsTest Iu-PS Interface Application provides: Emulation of RNC and SGSN nodes.

What is NBAP protocol?

NBAP is the protocol for signaling between UTRAN RNC and NodeB over Iub interface. The Iub interface can be either ATM-based or IP-based. In ATM-based Iub, NBAP is carried inside SAAL over ATM AAL2. In IP-based Iub, NBAP is carried inside SCTP over IP.

What are the main elements of UMTS?

UMTS specifies a complete network system, which includes the radio access network (UMTS Terrestrial Radio Access Network, or UTRAN), the core network (Mobile Application Part, or MAP) and the authentication of users via SIM (subscriber identity module) cards.

What is the difference between R99 and R4?

The most significant difference between R4 and R99 is that the R4 core network reflects the concept of NGN architecture. The circuit switched domain of R4 evolves from TDM central node switching to typical distributed architecture of packet voice and its service logic is separated from its lower-layer bearer.

What is the interface between RNC & SGSN?

In essence, UMTS IuPs interface is the Gateway to the World Wide Web. More precisely, IuPs, as shown in the figure, is the interface between the RNC (Radio Network Controller) and the SGSN (Serving GPRS Support Node). SGSN manages mobile location whether within the carrier’s network or roaming outside.

What is IUB in telecom?

Iub is the interface between an RNC and a Node B. Iur is the logical interface between two RNCs. Iu is the interconnection point between an RNC and the 3G Core Network.

What is utran in mobile communication?

UTRAN (short for “‘UMTS Terrestrial Radio Access Network”) is a collective term for the network and equipment that connects mobile handsets to the public telephone network or the Internet. The UTRAN allows connectivity between the UE (user equipment) and the core network.

What is UMTS signal?

UMTS (Universal Mobile Telecommunications Service) is a third-generation (3G) broadband, packet-based transmission of text, digitized voice, video, and multimedia at data rates up to 2 megabits per second (Mbps). UMTS is based on the Global System for Mobile (GSM) communication standard.

What is R4 network?

R4 instances offer up to 64 vCPUs and 488 GiB of DDR4 memory, and are powered by dual socket Intel® Xeon® E5 Broadwell processors (2.3 GHz). R4 provides up to 20 Gbps of network bandwidth with Elastic Network Adapter (ENA) based Enhanced Networking and 12 Gbps of dedicated throughput to EBS.

What are connection oriented messages in RANAP protocol?

.Connection-oriented messages are ones between a specific UE and the network, such as UE location update procedure and call procedure. Connectionless messages are ones pertaining to system maintenance and administration and affect part or all of UE users . Most of RANAP connectionless message may be up or down (except PAGING).

Which is signaling channel does RANAP work in?

RANAP handles signaling for the Iu-PS – RNC and 3G SGSN and Iu-CS – RNC and 3G MSC . It also provides the signaling channel to transparently pass messages between the User Equipment (UE) and the CN. In LTE, RANAP has been replaced by S1AP.

What is the role of RANAP in SCTP?

For Iu-ps transport RANAP is carried on SCTP if IP interface used on this. RANAP handles signaling for the Iu-PS – RNC and 3G SGSN and Iu-CS – RNC and 3G MSC . It also provides the signaling channel to transparently pass messages between the User Equipment (UE) and the CN. In LTE, RANAP has been replaced by S1AP.

Where is RANAP signalling protocol located in UMTS?

RANAP signalling protocol resides in the control plane of Radio network layer of Iu interface in the UMTS (Universal Mobile Telecommunication System) protocol stack. Iu interface is the interface between RNC (Radio Network Controller) and CN (Core Network). nb. For Iu-ps transport RANAP is carried on SCTP if IP interface used on this.
