Abstract
The present disclosure is related to methods and network nodes for enhanced NF registration and discovery. A method at a first network node for selecting a second network node to serve a UE includes determining the second network node based on at least first information indicating a pool and/or a source from which an IP address and/or an IP prefix are to be allocated to the UE.
Claims24
A method, performed by a first network node, for selecting a second network node to serve a User Equipment, the method comprising:
- determining the second network node based on at least first information indicating one or both of a pool and a source from which one or both of an Internet Protocol, address and an IP prefix are to be allocated to the UE.
(canceled)
A first network node, comprising:
- a processor;
- a memory storing instructions which, when executed by the processor, cause the processor to select a second network node to serve a User Equipment (UE) by configuring the processor to:
- determine the second network node based on at least first information indicating one or both of a pool and a source from which one or both of an Internet Protocol (IP) address and an IP prefix are to be allocated to the UE.
-19. (canceled)
A method performed by a third network node for enabling a second network node to be discoverable by a first network node, the method comprising:
- receiving, from one or more second network nodes, one or more seventh messages, each comprising second information indicating one or both of a pool and a source, from which one or both of an IP address and an IP prefix are able to be allocated, the one or both of the pool and the source being able to be handled by a corresponding second network node;
- receiving, from the first network node, a first message for discovering one or more second network nodes, the first message further comprising first information indicating one or both of a pool and a source from which one or both of an IP address and an IP prefix are to be allocated to a UE;
- determining at least one second network node in response to determining that the second information corresponding to the at least one second network node matches with the first information;
- transmitting, to the first network node, a second message indicating the determined at least one second network node;
- and
- thereby enabling the first network node to select a second network node from the determined at least one second network node for serving a UE.

A third network node, comprising:
- a processor;
- a memory storing instructions which, when executed by the processor, cause the processor to enable a second network node to be discoverable by a first network node by configuring the processor to:
- receive, from one or more second network nodes, one or more seventh messages, each comprising second information indicating one or both of a pool and a source, from which one or both of an IP address and an IP prefix are able to be allocated, the one or both of the pool and the source being able to be handled by a corresponding second network node;
- receive, from the first network node, a first message for discovering one or more second network nodes, the first message further comprising first information indicating one or both of a pool and a source from which one or both of an IP address and an IP prefix are to be allocated to a UE;
- determine at least one second network node in response to determining that the second information corresponding to the at least one second network node matches with the first information;
- transmit, to the first network node, a second message indicating the determined at least one second network node;
- and
- thereby enable the first network node to select a second network node from the determined at least one second network node for serving a UE.
