Title:
METHODS AND APPARATUSES FOR CONNECTION ESTABLISHMENT
Document Type and Number:
WIPO Patent Application WO/2020/168673
Kind Code:
A1
Abstract:
Methods and apparatuses for connection establishment are disclosed. According to an embodiment, a first network node receives, from a terminal device, a first request for establishment of a first connection that is a connection of a first type according to a first technology. The first request comprises a first indication about whether the terminal device supports a second connection that is a connection of the first type according to a second technology. The first network node sends, to a second network node, a second request for establishment of the first connection. The second request comprises the first indication. The first network node receives, from the second network node, a second indication about whether the second connection is supported by the second network node. The first network node sends the second indication to the terminal device.
