Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a source node may forward a first message between a user equipment (UE) and a core node via a distributed node, wherein the first message is a non-access stratum message. The source node may transmit, to a target node, a second message associated with a migration of the distributed node from the source node to the target node, wherein the second message identifies the forwarding of the first message. Numerous other aspects are described.
Claims25
A source node for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- forward a first message between a user equipment (UE) and a core node via a distributed node, wherein the first message is a non-access stratum message;
- and
- transmit, to a target node, a second message associated with a migration of the distributed node from the source node to the target node, wherein the second message identifies the forwarding of the first message.
A target node for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive a request, from a source node, to establish a connection with a distributed node connected to the source node;
- and
- receive, from the source node and based at least in part on receiving the request, a second message associated with migration of the distributed node from the source node to the target node, wherein the second message identifies forwarding of a first message between a core node and a user equipment (UE) via the distributed node, wherein the first message is a non-access stratum message.
A core node for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive, from a target node, an indication of support for a tracking area, wherein the tracking area is included in a registration area configured for a user equipment (UE) associated with a source node;
- and
- transmit a request that the target node page the UE using the tracking area.
A method of wireless communication performed by a source node, comprising:
- forwarding a first message between a user equipment (UE) and a core node via a distributed node, wherein the first message is a non-access stratum message;
- and
- transmitting, to a target node, a second message associated with a migration of the distributed node from the source node to the target node, wherein the second message identifies the forwarding of the first message.
