FIRST NODE, SECOND NODE AND METHODS PERFORMED THEREBY FOR HANDLING PACKET DUPLICATION IN A MULTI-HOP NETWORK NETWORK - A simplified explanation of the abstract

This abstract first appeared for US patent application 17919529 titled 'FIRST NODE, SECOND NODE AND METHODS PERFORMED THEREBY FOR HANDLING PACKET DUPLICATION IN A MULTI-HOP NETWORK NETWORK

Simplified Explanation

The abstract describes a method for handling packet transmission in a communications network, specifically indicating whether to duplicate packets and supporting duplication over various network layers and channels.

• The method involves a first node in a communications network handling packet transmission from a sending node to a receiving node.
• The first node sends an indication to a second node in the network explicitly stating whether to duplicate the packets.
• The indication also specifies if duplication of packets is supported and/or activated over different network layers and channels.
• This includes options such as GTP layer, GTP tunnels, BAP layer, and Backhaul Radio Link Channels between nodes.
• The method may involve multiple intermediate nodes in the network for packet transmission.

Potential Applications

This technology could be applied in various communication networks where packet duplication and support over different network layers are required.

Problems Solved

1. Efficient packet transmission in complex communication networks. 2. Ensuring packet duplication is supported and activated as needed.

Benefits

1. Improved reliability in packet transmission. 2. Enhanced network performance by supporting duplication over different network layers. 3. Flexibility in managing packet duplication based on network requirements.

Potential Commercial Applications

Optimizing packet transmission in 5G networks for enhanced performance and reliability.

Possible Prior Art

Prior art in the field of packet duplication and transmission optimization in communication networks may exist, but specific examples are not provided in the abstract.

How does this method impact network latency in packet transmission?

The abstract does not mention the potential impact of this method on network latency. Further research or testing may be needed to determine the latency implications of packet duplication and support over different network layers.

What are the potential security implications of packet duplication in communication networks?

The abstract does not address the security aspects of packet duplication. It would be essential to investigate how packet duplication over various network layers could affect the security of the communication network and potential vulnerabilities that may arise.

Original Abstract Submitted

A method performed by a first node (), for handling transmission of one or more packets from a sending node () to a receiving node () in a communications network (). The communications network () comprises at least one intermediate node () between the sending node () and the receiving node (). The first node () sends () an indication to a second node () in the communications network (). The indication explicitly indicates whether or not at least one of: a) to duplicate the one or more packets, and b) duplication of the one or more packets is supported and/or activated, over at least one of: i) a GTP layer, ii) one or more GTP tunnels, iii) a BAP layer and iv) over one or more Backhaul Radio Link Channels, between the first node (), and/or the second node (), and one or more next hop nodes ().
