Problems solved by technology

However, any method has its own disadvantages
Potentially increased network signaling overhead in case of network coordination for RAR contention resolution
Also, backhaul limitations can be a notable challenge, especially for some applications, for reasons of latency and capacity
In case the RAR selection is handled by the UE, the disadvantages may be energy consumption due to UE-side processing, and less network traffic steering control, the latter meaning that the network may not be able to determine which network node the UE should attach to first node
[0012] Another problem with existing methods is that sending more RAR messages than required can cause additional interference, reducing performance

Abstract

A method performed by a first network node (111) for handling an access request from a wireless device (130). A wireless device (130) and a first network node (111) operate in a wireless communication network (100). A first network node (111) receives (401) a first message comprising an access request from a wireless device (130). The first network node (111) determines (402) a delay for sending a second message to the wireless device (130) in response to receiving the first message. The first network node (111) then sends (403) said second message to the wireless device (130) using the determined delay, said second message comprising a response to said access request.

Description

technical field [0001] The present disclosure generally relates to a first network node and method thereof for handling access requests from wireless devices. The present disclosure also generally relates to a wireless device and method thereof for receiving a response to an access request from a first network node. The present disclosure also generally relates to a second radio node and a method thereof for obtaining a first indication from a communication device. Embodiments herein also relate to computer programs for performing these methods and computer-readable storage media storing the computer programs. Background technique [0002] A communication device such as a terminal is also referred to as eg User Equipment (UE), wireless device, mobile terminal, wireless terminal and / or mobile station. A wireless device is enabled to communicate wirelessly in a cellular communication network or wireless communication system (sometimes also called a cellular radio system or c...
