Method, apparatus and computer program for indicating that a source access node connected to the first public land mobile network and a target access node connected to the second public land mobile network area same access node

An apparatus comprising:

• at least one processor;
• and
• at least one memory storing instructions of a first access and mobility management function of a first public land mobile network, wherein the instructions, when executed by the at least one processor, cause the apparatus to perform operations, the operations comprising:
• determining that a user equipment served by the first access and mobility function is in a location or area associated with a second public land mobile network;
• determining that handover of the user equipment from the first access and mobility management function to a second access and mobility management function of the second public land mobile network is required;
• sending a request to update a user equipment context for the user equipment, wherein the request comprises an indication that a source access node connected to the first public land mobile network and a target access node connected to the second public land mobile network are a same access node;
• and
• receiving a response to the request, the response comprising the indication that the source access node and the target access node are the same access node.
