What is LTE attach procedure?
The target of LTE attach procedure, is to register the UE to the network, and to make the UE ,able to send and receive data, to and from the PDN.
and this procedure includes, attach request, authentication and security, update location, and EPS bearer establishment..
What is Sgsn in LTE?
The Serving GPRS Support Node (SGSN) is a main component of the GPRS network, which handles all packet switched data within the network, e.g. the mobility management and authentication of the users. The SGSN performs the same functions as the MSC for voice traffic.
What is Gn Gp Interface?
Gn/Gp interface, is the interface between the SGSNs and the GGSNs. ‘Gn interface’ is the interface between the SGSNs and the GGSNs when they exist within the same mobile network.
What is the difference between SGSN and GGSN?
To summarise; SGSN stands for Serving GPRS Support Node and is a network entity that provides the packet-switched capability to mobile networks. GGSN stands for Gateway GPRS Support Node and is a gateway situated between SGSN and external data networks.
What is radio bearer in LTE?
Bearer is just a virtual concept. It defines how the UE data/signaling are treated when it travels across the network.
What is default LTE bearer?
The first EPS bearer that is activated when a PDN connection is established in LTE is called the “default bearer”. This bearer remains established during the lifetime of the PDN connection.
What is GSM in telecommunication?
The Global System for Mobile Communications (GSM) is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation (2G) digital cellular networks used by mobile devices such as mobile phones and tablets.
How do I activate my PDP?
PDP context activation is initiated by the UE and changes the session management state to active, creates the PDP context, receives the IP address and reserves radio resources. After a PDP context activation the UE is able to send IP packets over the air interface.
What is the function of Ggsn?
The gateway GPRS support node (GGSN) converts the incoming data traffic coming from the mobile users through the Service gateway GPRS support node (SGSN) and forwards it to the relevant network, and vice versa. The GGSN and the SGSN together form the GPRS support nodes (GSN).
What is the use of SGSN and GGSN?
SGSN and GGSN are the two core network elements of the general packet radio service which enables Internet to become mobile. It allows mobile users to access text based data services without continuously occupying a specific radio channel (which is not the case when you access voice channel).
What’s the difference between IPv6 and IPv4?
KEY DIFFERENCE IPv4 is 32-Bit IP address whereas IPv6 is a 128-Bit IP address. IPv4 is a numeric addressing method whereas IPv6 is an alphanumeric addressing method. IPv4 binary bits are separated by a dot(.) whereas IPv6 binary bits are separated by a colon(:).
What is a PDN in LTE?
The PDN GW is the point of interconnect between the EPC and the external IP networks. These networks are called PDN (Packet Data Network), hence the name. The PDN GW routes packets to and from the PDNs. The PDN GW also performs various functions such as IP address / IP prefix allocation or policy control and charging.
What does Sgsn stand for?
Serving GPRS Support NodeThe Serving GPRS Support Node (SGSN) is the node that is serving the MS/UE. The SGSN supports GPRS and/or UMTS. The SGSN keeps track of the location of an individual MS/UE and performs security functions and access control.
What is a PDP context?
Packet Data Protocol (PDP) context is a data structure that allows the device to transmit. data using Internet Protocol. It includes the device’s IP address, IMSI and additional. parameters to properly route data to and from the network.
What is PDP type?
PDP type is the type of the IP address assigned to the PDP. PDP type maybe one of the following, IPv4. IPv6.
What is PDP context in LTE?
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 older architectures, bearers were known as packet data protocol (PDP) contexts. …
What is IPv4v6?
Dual Address PDN/PDP Type The dual address Packet Data Network/Packet Data Protocol (PDN/ PDP) Type (IPv4v6) is used in 3GPP context in many cases as a synonym for dual-stack, i.e., a connection type capable of serving both IPv4 and IPv6 simultaneously.
