Communication paging based on multiple paths

Access and Mobility Management Function (AMF) for performing communication, the AMF comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
• receiving a first registration request message from a user equipment (UE) over a New Generation Radio Access Network (NG-RAN);
• transmitting, in response to the first registration request message, a first registration accept message to the UE over the NG-RAN;
• receiving, in response to the first registration request message, a second registration request message from the UE over the NG-RAN;
• transmitting, in response to the second registration request message, a second registration accept message to the UE over the NG-RAN;
• and
• transmitting a paging message to the UE over the NG-RAN,
• wherein the second registration request message includes information indicating that a second path, over which the second registration request message was sent, has been added as a path for the UE,
• wherein the paging message is transmitted to the UE over a paging path,
• wherein the paging path being determined to be one of the second path or the first path over which the first registration request message was transmitted.

A method for performing communication, the method performed by a User Equipment (UE), and comprising:

• transmitting a first registration request message to an Access and Mobility Management Function (AMF) over a New Generation Radio Access Network (NG-RAN);
• receiving, in response to the first registration request message, a first registration accept message from the AMF over the NG-RAN;
• transmitting, in response to the first registration request message, a second registration request message to the AMF over the NG-RAN;
• receiving, in response to the second registration request message, a second registration accept message from the AMF over the NG-RAN;
• and
• receiving a paging message from the AMF over the NG-RAN,
• wherein the second registration request message includes information indicating that a second path, over which the second registration request message was sent, has been added as a path for the UE,
• wherein the paging message is transmitted to the UE over a paging path, and
• wherein the paging path being determined to be one of the second path or the first path over which the first registration request message was transmitted.
