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.
What is the use of Bssgp in GPRS transmission plane protocol?
BSS GPRS protocol (BSSGP). This layer conveys routing and QoS-related information between the BSS and SGSN. Network service (NS). It transports BSSGP PDUs and is based on a frame relay connection between the BSS and SGSN.
What is a GB link?
3.8 Gb Interface. The Gb interface connects the BSS and the SGSN. It allows for the exchange of signaling information and user data. Transmission over the Gb interface is based on frame relay. Point-to-point (PTP) physical lines or an intermediate frame relay network can be used to connect the SGSN and the BSS.
What is Gn interface?
‘Gn interface’ is the interface between the SGSNs and the GGSNs when they exist within the same mobile network. Gn Interface. Learn Mobile Packet Core Network in 5 Hours. Online Course. In case of roaming scenario, the user is traveling to another mobile network.
What is the difference between GTP-C and GTP-U?
GTP-C supports transport of control packets in IPv4 format. GTP-U— Transports user data within the core GPRS network and between the Radio Access Network (RAN) and the core network. GTP-U supports IPv4 and IPv6 user data, but transport is IPv4.
What is the full form of BSSGP and its functionality?
BSSGP is a protocol used in the GPRS mobile packet data system. It denotes Base Station System GPRS Protocol.
What are the characteristics of GPRS?
2.5 GPRS characteristics [1]:
- transmission modes: send and receive data in packet transfer mode; cost effective and efficient use of network resources.
- traffic characteristics: intermittent, bursty data transmissions; frequent transmissions of small volumes of data; infrequent transmission of large volumes of data.
What is gigabit and Gigabyte?
A gigabit is 109 or 1,000,000,000 bits. It is one-eighth the size of a gigabyte (GB), which means a gigabit is eight times smaller than a gigabyte. Additionally, Gigabits are mostly used to measure data transfer rates of local networks (Ethernet) and Input/Output (I/O) connections.
What is S5 interface?
S5 interface It provides user plane tunnelling and tunnel management between Serving GW and PDN GW. It is used for Serving GW relocation due to UE mobility and if the Serving GW needs to connect to a non-collocated PDN GW for the required PDN connectivity.
What is S11 interface?
S11 – This is the interface between the MME and S-GW in an LTE network. The interface is based on Gn/GTP-Control (GTP-C) (interface between SGSN-GGSN) with some additional functions for paging coordination, mobility compared to the legacy Gn/GTP-C (SGSN-GGSN) interface. S11 is a many-to-many interface.
