What are RANAP functionality?

RANAP operates over the Iu-PS interface and provides two main functions; the support of AS (Access Stratum) signalling between the RNC and the SGSN and the encapsulation of NAS (Non Access Stratum) signalling passing between the mobile and the core network.

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.

What is the difference between RRC and RAB?

In our scenario, the RRC are the Rails, and RAB is the full service of sending data between the UE and the CN. Note: the RRC is in Layer 3 – control plane, while the RAB occurs between the UE and CN, in the user plane. The railcars are the RBs, and convey the information in the radio path.

What is the interface between RNC and MSC?

The interface between the RNC and the Circuit Switched Core Network (CS-CN) is called Iu-CS and between the RNC and the Packet Switched Core Network is called Iu-PS. Other interfaces include Iub (between the RNC and the Node B) and Iur (between RNCs in the same network).

What is RNC in telecom?

Plays a role similar to the BSC in a GSM network, but supports B nodes used in UMTS networks.

What is SRB and DRB?

In LTE there are two main types of bearers, namely the SRB (Signalling Radio Bearer) and the DRB (Data Radio Bearer). The DRB is used to carry the data associated with an EPS bearer.

What is the role of RNC?

The Republican National Committee (RNC) is a U.S. political committee that assists the Republican Party of the United States. It is responsible for developing and promoting the Republican brand and political platform, as well as assisting in fundraising and election strategy.

What is SRB and DRB in 5G?

There are two types of bearers SRB and DRB (Data radio bearer). SRB (Signaling Radio Bearer) is a type of radio bearer that carries signaling message i.e. RRC or NAS messages or both. DRB is used to carry the data associated with EPS bearer.

What are the functions of RNC and Node B in UMTS?

The RNC undertakes the radio resource management and some of the mobility management functions, although not all. It is also the point at which the data encryption / decryption is performed to protect the user data from eavesdropping. Node B: Node B is the term used within UMTS to denote the base station transceiver.

What is the role of the RNC in the 3G cellular data network architecture What role does the RNC play in the cellular voice network?

What is the role of the RNC in the 3G cellular data network architecture? What role does the RNC play in the cellular voice network? base transceiver stations. The RNC connects to both the circuit-switched cellular voice network via an MSC, and to the packet-switched Internet via an SGSN.

Which interface is used for the RANAP protocol?

RANAP is carried over Iu-interface. 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.

What is the SCCP protocol used for RANAP?

SCCP: Typically, RANAP uses SCCP Class-2 as its transport protocol. The SSN normaly used for RANAP is 142. XXX – Add example decoded traffic for this protocol here (as plain text or Wireshark screenshot). The RANAP dissector is fully functional.

What SSN is used for RANAP?

The SSN normaly used for RANAP is 142. XXX – Add example decoded traffic for this protocol here (as plain text or Wireshark screenshot). The RANAP dissector is fully functional. The SCCP SSN used to carry RANAP is a preference in the RANAP dissector; this is useful if you have RANAP carried over an SSN other than the default of 142.

Where can I find a complete set of RANAP events?

A complete set of events that can be generated with the RANAP interface can be found here. dsTest provides rich sets of measurements that include but are not limited to: See our Online Help for RANAP measurements, SCCP measurements, M3UA measurements, and SCTP measurements.
