Network Nodes and Methods Therein for Facilitating Application Context Relocation

A method in a source Edge Application Server (EAS), the method comprising:

• transmitting a request for EAS discovery to a source Edge Enabler Server (EES);
• receiving, from the source EES, a response containing information indicating one or more discovered EASs;
• selecting one of the one or more discovered EASs as a target EAS;
• and
• transmitting information indicating the selected target EAS to the source EES.

A method in a source Edge Enabler Server (EES), the method comprising:

• receiving, from a source Edge Application Server (EAS), a request for EAS discovery;
• transmitting, to the source EAS, a response containing information indicating one or more discovered EASs;
• and
• receiving, from the source EAS, information indicating a selected target EAS, the selected target EAS being selected from the one or more discovered EASs.

A network node, comprising a communication interface, a processor and a memory, the memory comprising instructions executable by the processor whereby the network node is operative to, when implementing a source Edge Application Server (EAS):

• transmit a request for EAS discovery to a source Edge Enabler Server (EES);
• receive, from the source EES, a response containing information indicating one or more discovered EASs;
• select one of the one or more discovered EASs as a target EAS;
• and
• transmit information indicating the selected target EAS to the source EES.
