Abstract: Described herein is a User Plane Function, UPF, network node, configured for data forwarding for selective activation of a Secondary Cell Group, SCG, for serving a User Equipment, UE, the UPF network node comprising: at least one processor, and at least one memory storing instructions that, when executed by the at least one processor, cause the UPF network node at least to: receive an indication message for starting data forwarding; and execute data forwarding on the basis of the received indication message.

Abstract: A system and method for extracting mathematical formulae from the one or more technical documents is disclosed. The method includes identifying variables and a concept associated with each of the variables from the one or more technical documents. The method includes determining interdependencies between variables in the extracted mathematical formulae based on the identified variables and the concept associated with the variables. The method includes generating the knowledge base based on the determined interdependencies. The method further includes providing access to the knowledge base to an end-user.
