Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a cellular modem may transmit, to an applications processor, an indication to use a non-Third Generation Partnership Project (non-3GPP) interworking function (N3IWF) for non-access stratum (NAS) signaling. Accordingly, the cellular modem may establish a first virtual interface with the applications processor. The cellular modem may further perform an Internet Key Exchange (IKE) procedure with a core network using the first virtual interface and the N3IWF and transmit a key generated during the IKE procedure to the applications processor. Numerous other aspects are described.
Claims20
A user equipment (UE) for wireless communication, comprising:
- an applications processor configured to:
- transmit, to a cellular modem, a request to use a non-Third Generation Partnership Project (non-3GPP) interworking function (N3IWF) for non-access stratum (NAS) signaling, wherein the request is based at least in part on a policy associated with the UE;
- receive, from the cellular modem using a first virtual interface, an NAS payload to transmit over the N3IWF;
- transmit, to the cellular modem and based at least in part on receiving the NAS payload, an indication of a source Internet protocol (IP) address and a destination IP address associated with a core network;
- encode the NAS payload using transmission control protocol (TCP);
- and
- instruct a WiFi modem to transmit the encoded NAS payload.
A method for wireless communication at a user equipment (UE), comprising:
- transmitting, to a cellular modem, a request to use a non-Third Generation Partnership Project (non-3GPP) interworking function (N3IWF) for non-access stratum (NAS) signaling, wherein the request is based at least in part on a policy associated with the UE;
- receiving, from the cellular modem using a first virtual interface, an NAS payload to transmit over the N3IWF;
- transmitting, to the cellular modem and based at least in part on receiving the NAS payload, an indication of a source Internet protocol (IP) address and a destination IP address associated with a core network;
- encoding the NAS payload using transmission control protocol (TCP);
- and
- instructing a WiFi modem to transmit the encoded NAS payload.
A non-transitory computer-readable medium storing a set of instructions for wireless communication includes one or more instructions that, when executed by an applications processor, cause the applications processor to:
- transmit, to a cellular modem, a request to use a non-Third Generation Partnership Project (non-3GPP) interworking function (N3IWF) for non-access stratum (NAS) signaling, wherein the request is based at least in part on a policy associated with the applications processor;
- receive, from the cellular modem using a first virtual interface, an NAS payload to transmit over the N3IWF;
- transmit, to the cellular modem and based at least in part on receiving the NAS payload, an indication of a source Internet protocol (IP) address and a destination IP address associated with a core network;
- encode the NAS payload using transmission control protocol (TCP);
- and
- instruct a WiFi modem to transmit the encoded NAS payload.
