What is GPRS protocol stack?
The GPRS protocol stack is a key element within the overall GPRS handset or base station. It enables the different functions to be split into different layers so that the correct priorities. The protocol stack enables the exchanges to take place in the required fashion and to be managed in an orderly fashion.
Which protocol layer is used to carry bearer traffic from eNodeB to serving gateway?
The radio resource control (RRC) protocol is known as layer 3 in the AS protocol stack and in 3GPP RAN terminology [2]. It is the main controlling function in the AS responsible for establishing the radio bearers and configuring all lower layers using RRC signaling between the eNB and the UE [16].
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. Mobile Originating, Mobile Terminating, Location Updating, GPRS Attach, and Detach procedures.
What is IuPs and IuCS?
IuPS interface works 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. IuCS interface in UMTS links the RNC (Radio Network Controller) with a 3G MSC (3G Mobile Switching Centre).
Is GPRS a protocol?
GPRS Tunnelling Protocol (GTP) is a group of IP-based communications protocols used to carry general packet radio service (GPRS) within GSM, UMTS and LTE networks. In 3GPP architectures, GTP and Proxy Mobile IPv6 based interfaces are specified on various interface points.
What is the difference between GGSN and PGW?
P-GW—In 2G and 3G networks, the node that handled all user packets to and from the user equipment is called the GGSN. In the LTE architecture, this is the Packet Gateway (P-GW) or sometimes seen as the Packet Data Network Gateway (PDN-GW).
What is the interface between HSS and PCRF?
Diameter Interfaces
| Interface | Network location |
|---|---|
| S6d interface | Between SGSN and HSS, Subscription and Authentication Data |
| S7c interface | Transfer of (QoS) policy information from PCRF to the S-GW. |
| S9 interface | Between PCRF in the HPLMN (H PCRF) and a PCRF in the VPLMN (V PCRF) |
| S13 and S13′ interface | Between EIR and MME/SGSN |
Which is the multiple access technology used in UMTS?
W-CDMA
UMTS uses wideband code-division multiple access (W-CDMA) radio access technology to offer greater spectral efficiency and bandwidth to mobile network operators.
What is Ranap protocol?
In telecommunications networks, RANAP (Radio Access Network Application Part) is a protocol specified by 3GPP in TS 25.413 and used in UMTS for signaling between the Core Network, which can be a MSC or SGSN, and the UTRAN. Iu interface is the interface between RNC (Radio Network Controller) and CN (Core Network).
What is the interface between RNC and MGW?
QoS in Mobile IP Networks This interface is between the 3G RNC and the MGW. This interface services the voice traffic and signaling to and from the core network. In the Release 99 specification, the interface from the RNC into the MGW is ATM, which the MGW then converts to TDM for connection to the legacy MSC.
