What is PDP Context Activation?
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 difference between a GPRS Attach and a PDP Context Activation?
PDP Context Activation: After the GPRS attach, the MN must activate a PDP address (or IP address) to begin packet data communication. Activation of a PDP address creates an association between the MN’s current SGSN and the GGSN that anchors the PDP address. A record of such an association is known as the PDP context.
What is PDP context info?
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 the difference between SGSN and 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 PDP in Internet?
Packet Data Protocol in wireless GPRS/HSDPA networks.
What is PDP in mobile?
A Packet Data Protocol (PDP) context offers a packet data connection over which a device and the mobile network can exchange IP packets. As per 3GPP standards, a device can have more than one PDP context activated at a time.
What is PDP type?
Packet Data Protocol Type A Packet Data Protocol Type (PDP Type) identifies the used/allowed protocols within the PDP context. Examples are IPv4, IPv6, and IPv4v6 (dual-stack).
What is PDN context?
A PDN is responsible for the IP address/prefix management. On an UE a PDN Connection is equivalent (or visible to an IP stack) as a virtual network interface. Pre-Release-8 “equivalent” for a PDN Connection is the PDP Context (used in GPRS).
What is PDN in LTE?
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 is the purpose of SGSN?
A SGSN is responsible for the delivery of data packets from and to the mobile stations within its geographical service area. Its tasks include packet routing and transfer, mobility management (attach/detach and location management), logical link management, and authentication and charging functions.
What is SGSN in LTE?
Part of the GPRS infrastructure, the SGSN provides switching functionality, security and authentication via the HLR for GPRS users.
What is PDP process?
What is PDP? A performance development plan is a tool for improving employee performance. The PDP process helps managers and employees identify areas for improvement, set goals, measure progress, and outline a strategy to achieve those objectives.
What is PDP IP address?
The PDP (Packet Data Protocol) Address conforms to the standard addressing scheme of the respective network layer service used, e.g. IPv4 (IP version 4), IPv6 (IP version 6) or X. 25 etc. If you enjoy using our glossary, here are some other useful resources you might like…
What is PDP connection?
What is PDP in APN settings?
APN is stored as part of PDP (Packet Data Profile) profiles along with IP type, PDP IP address , data and header compressions. Each PDP profile will have it’s own APN information. Using the AT Command Tester tool, you can read the APN information from the cellular modules.
What is PDN type in LTE?
Description. Specify the type of Packet Data Network (PDN) for rule matching. If the type of PDN of the user equipment (UE) matches the type of PDN specified here, then the actions specified for the service selection profile are performed.
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 is the difference between PDN and APN?
In a mobile network, the access point name (APN) is the virtual private network (VPN) that connects the user equipment through the Packet Data Network Gateway (P-GW) to the Packet Data Network (PDN). User equipment can access many APNs, which are domain names and associated parameters, and one is the default APN.
What is the role of SGSN and GGSN components?
The GGSN, sometimes known as a wireless router, works in tandem with the Serving GPRS Support Node (SGSN) to keep mobile users connected to the Internet and IP-based applications. The GGSN converts incoming data traffic from mobile users (via the SGSN) and forwards it to the relevant network, and vice versa.
What is SGW and PGW?
Cisco Serving Gateway (SGW) is a critical network function for the 4G mobile core network, known as the evolved packet core (EPC). The SGW resides in the user plane where it forwards and routes packets to and from the eNodeB and packet data network gateway (PGW).
What is PDN in telecom?
A public data network (PDN) is a network established and operated by a telecommunications administration, or a recognized private operating agency, for the specific purpose of providing data transmission services for the public.
Why is PDP important?
A PDP provides a visual outline and roadmap for growth—you can clearly see gaps in experience, knowledge and skills, and can easily identify necessary activities to fill them. Plus, it helps you create a structured plan and timeline for achieving your goals.
What are the benefits of PDP?
The benefits of a PDP are:
- It provides you with clear goals.
- It helps you to identify your strengths and weaknesses.
- It improves your employability.
- It improves your performance.
- It increases your motivation.
- It helps track your progress.
- It improves your sense of purpose.
