Data connection establishment in response to a disaster condition

An apparatus for performing a network function, the apparatus further comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the apparatus to:
• receive a registration request from a user equipment (UE) to register with a first communication network (CNET);
• transmit a registration accept to the UE, wherein the registration accept comprises an indication that a restricted data connection is allowed;
• transmit, to a first network function, a request during a data connection establishment procedure for the restricted data connection, wherein the request comprises:
• an indication that the data connection is requested in response to a disaster condition in a second CNET;
• a second CNET identifier;
• a request for confirmation from the first network function that the UE has successfully registered with the second CNET;
• or a combination thereof;
• and
• receive a notification from the first network function that the UE has successfully registered with the second CNET, wherein a plurality of destination addresses are determined in the second CNET by resolving a fully-qualified domain name corresponding to the second CNET to a plurality of internet protocol addresses.

A user equipment (UE), comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the UE to:
• transmit a first request to connect with a first communication network (CNET);
• receive a registration accept comprising an indication that a restricted data connection is allowed;
• transmit a request for establishing the restricted data connection with the first CNET;
• and
• receive a response to the request for establishing the restricted data connection, wherein the response indicates that the restriction of the data connection applies to traffic transmitted toward a plurality of destination addresses in a second CNET, the plurality of destination addresses obtained by resolving a fully-qualified domain name corresponding to the second CNET to a plurality of internet protocol addresses.

A processor for wireless communication, comprising:

• at least one controller coupled with at least one memory and configured to cause the processor to:
• transmit a first request to connect with a first CNET;
• and
• receive a registration accept comprising an indication that a restricted data connection is allowed;
• wherein:
• the at least one controller is configured to cause the processor to transmit a request for establishing the restricted data connection with the first CNET;
• and
• the at least one controller is configured to cause the processor to receive a response to the request for establishing the restricted data connection, wherein the response indicates that the restriction of the data connection applies to traffic transmitted toward a plurality of destination addresses in a second CNET, the plurality of destination addresses obtained by resolving a fully-qualified domain name corresponding to the second CNET to a plurality of internet protocol addresses.
