Third generation partnership project (3GPP) service delivery to non-3GPP user devices over 3GPP N1 links

A Third Generation Partnership Project (3GPP) gateway serves a non-Third Generation Partnership Project (non-3GPP) user device over a 3GPP N1 link. The gateway receives a transaction request from the non-3GPP user device. The gateway translates the transaction request into a 3GPP request. The gateway transfers the 3GPP request to a 3GPP network and receives an authentication request from the 3GPP network. The gateway generates and transfers an authentication response based on the transaction request and the authentication request to the 3GPP network. In response to the authentication, the gateway establishes the 3GPP N1 link with the 3GPP network for the non-3GPP user device. The gateway exchanges user data with the non-3GPP user device. The gateway interworks the user data and N1 signaling. The gateway exchanges the N1 signaling with the 3GPP network. The 3GPP network interworks the N1 signaling and the user data and exchanges the user data.
