Abstract
Embodiments herein relate to apparatuses and methods for relaying a data session of a first wireless device via a second radio access node in a radio communications network, wherein said data session is ongoing towards the first gateway node via a first radio access node in the radio communications network. Embodiments herein also relate to a first and a second wireless device, a ProSe function node, a MME, a gateway node and methods therein.
Claims14
A method performed by a first wireless device for relaying a data session via a second radio access node in a radio communications network, the method comprising:
- establishing a data session towards a first gateway node via a first radio access node in the radio communications network;
- discovering radio connectivity towards the second radio access node;
- determining that the ongoing data session is to be relayed via the second radio access node;
- and
- transmitting a relay request message to a proximity service function, ProSe, node configured to operatively manage relaying of data sessions in the radio communications network, comprising relay information causing the ongoing data session to be relayed from the first wireless device to the first gateway node via the second radio access node while maintaining session continuity towards the first gateway node, wherein the data packets of the ongoing data session are at least partly tunneled between the first gateway node and the second radio access node.
A first wireless device for relaying a data session via a second radio access node in a radio communications network, the first wireless device being configured to:
- establish a data session towards a first gateway node via a first radio access node in the radio communications network;
- discover radio connectivity towards the second radio access node,
- determine that the ongoing data session is to be relayed via the second radio access node, and
- transmit a relay request message to a proximity service function, ProSe, node configured to operatively manage relaying of data sessions in the radio communications network, comprising relay information causing the ongoing data session to be relayed from the first wireless device to the first gateway node via the second radio access node while maintaining session continuity towards the first gateway node, wherein the data packets of the ongoing data session are at least partly tunneled between the first gateway node and the second radio access node.
