Location Based Selection of Localized Proxy Application Server

A session management function (SMF) comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the SMF to:
• receive, from a wireless device, a packet data unit (PDU) session establishment request message;
• send, to a network node, a request message for subscription information of the wireless device;
• receive, from the network node, a response message comprising subscription information indicating an identifier of a first local proxy application server for an application location, wherein the application location identifies a user plane access to a data network;
• and
• send, to the wireless device, a PDU session establishment accept message comprising the identifier of the first local proxy application server.

A system comprising:

• a session management function (SMF) comprising:
• one or more first processors;
• and
• first memory storing first instructions that, when executed by the one or more first processors, cause the SMF to:
• receive, from a wireless device, a packet data unit (PDU) session establishment request message;
• send, to a network node, a request message for subscription information of the wireless device;
• receive, from the network node, a response message comprising subscription information indicating an identifier of a first local proxy application server for an application location, wherein the application location identifies a user plane access to a data network;
• and
• send, to the wireless device, a PDU session establishment accept message comprising the identifier of the first local proxy application server;
• and
• a network node comprising:
• one or more first processors;
• and
• second memory storing second instructions that, when executed by the one or more second processors, cause the network node to:
• receive the request message for subscription information of the wireless device;
• send the response message comprising the subscription information.
