Direct User Equipment to User Equipment Without Data Network Access Identifier

A computer program product embodied on a non-transitory computer-readable medium in which a computer program is stored that, when being executed by a computer, is configured to provide instructions to control or carry out the following:

• detecting in a communications network, by an application function, a request from a user equipment for direct peer-to-peer communication with at least one other user equipment, wherein the direct communication is performed without an application in a data center identified by a data network access identifier;
• instructing the network, by the application function, to set up said direct communication with the at least one other user equipment;
• gathering information, by the application function, during establishment/deestablishment of a packet data unit session with user equipment, of the at least one other user equipment, participating in the direct communication;
• and
• coordinating connectivity by the application function between the user equipment and the other participating user equipment based on the received information.

An apparatus comprising:

• at least one processor;
• and
• at least one non-transitory memory including computer program code, wherein the at least one memory and the computer code are configured, with the at least one processor, to cause the apparatus to at least perform the following:
• detecting in a communications network, by an application function, a request from a user equipment for direct peer-to-peer communication with at least one other user equipment, wherein the direct communication is performed without an application in a data center identified by a data network access identifier;
• instructing the network, by the application function, to set up said direct communication with the at least one other user equipment;
• gathering information, by the application function, during establishment/deestablishment of a packet data unit session with user equipment, of the at least one other user equipment, participating in the direct communication;
• and
• based on the received information, coordinating connectivity by the application function between the user equipment and the other participating user equipment.
