Problems solved by technology

In addition to signaling overhead and processing overhead, there is also the problem of large delays in the initial packet when establishing a connection
However, there are many conceivable attack vectors, and in view of a denial of service attack, it is generally dangerous to have a procedure in which low traffic from a host causes a lot of work for the network

Embodiment Construction

[0067] The present invention relates to an access node device for forwarding data packets in a communication network and a corresponding method, where the communication network is, for example, LTE, wireless LAN (WLAN), Universal Mobile Telecommunications System (UMTS) ), Code Division Multiple Access (CDMA) 2000, Worldwide Interoperability for Microwave Access (WiMAX) or any other suitable communication network.

[0068] The communication network to which the user equipment or user node is connected will be referred to as an access network or a radio access network (Radio Access Network, RAN). According to the present invention, two different modes—namely stateless mode or stateful mode—can be used to transmit data packets in the network, where, in the stateless mode, the access network is performing minimal processing of packets— —For example, without using additional encryption or quality of service mechanisms — the packet is forwarded through a predetermined default path; in ...

Abstract

The present invention relates to access node device (1) arranged for receiving and forwarding data packets in a communication network (2), the device comprising at least one processor (20) arranged to: receive data packets from an user node (3); and forward the data packets in a stateless mode over a first path to a destination gateway node (4), the first path being a default path, or forward the data packets in a stateful mode over a second path to a destination node, the second path being determined by user and / or session specific information for said user node (3). Furthermore, the invention also relates to a corresponding gateway node device, a method in an access node, a method in a gateway node, a computer program, and a computer program product thereof.

Description

Technical field [0001] The invention relates to an access node device for receiving and forwarding data packets in a communication network. In addition, the present invention also relates to corresponding gateway node devices, methods in access nodes, methods in gateway nodes, computer programs, and computer program products. Background technique [0002] The applications running on mobile devices are becoming more and more diverse, which places new requirements on wireless communication networks. Currently, smartphones, laptops and tablets are the most commonly used mobile devices, but it is expected that in the future the following machines will become the most common devices in wireless communication networks: the machine communicates with other machines without human intervention . [0003] The current wireless communication is not completely suitable for this type of communication, especially for the communication form that occasionally sends a small amount of data, the curr...
