Management of identifiers in an integrated access and backhaul network

A central entity in an integrated access and backhaul (IAB) network, comprising:

• one or more memories;
• and
• one or more processors coupled to the one or more memories, the one or more processors configured to:
• provide, based at least in part on a change of a first donor distributed unit associated with an IAB node to a second donor distributed unit in the IAB network, a request for a network address;
• receive, based at least in part on providing the request, information indicating a usage for the network address;
• and
• provide, to the IAB node and based at least in part on the information indicating the usage for the network address, updated transport network layer information identifying an Internet Protocol (IP) address for a non-user equipment (UE)-associated service and a UE-associated service, wherein the IP address is the same for the non-UE-associated service and the UE-associated service.

A method of wireless communication performed by a central entity in an integrated access and backhaul (IAB) network, comprising:

• providing, based at least in part on a change of a first donor distributed unit associated with an IAB node to a second donor distributed unit in the IAB network, a request for a network address;
• receiving, based at least in part on providing the request, information indicating a usage for the network address;
• and
• providing, to the IAB node and based at least in part on the information indicating the usage for the network address, updated transport network layer information identifying one or more Internet Protocol (IP) addresses for a non-user equipment (UE)-associated service and a UE-associated service, wherein the IP address is the same for the non-UE-associated service and the UE-associated service.
