Description

Intelligent access traffic switching, steering and splitting Technical Field Various example embodiments relate generally to wireless networks and, more particularly, to intelligent access traffic handoff, steering, and offloading. Background An access traffic directed handover and offloading (ATSSS) feature is a feature that may be supported by User Equipment (UE) and fifth generation (5G) core networks. ATSSS features enable a Multiple Access (MA) Protocol Data Unit (PDU) connection service that allows exchange of PDUs between a UE and a data network (e.g., the internet) by using both a third generation partnership project (3 GPP) access network and a non-3 GPP access network, and two separate N3/N9 tunnels between a PDU Session Anchor (PSA) that terminates the N6 interface of a PDU session within a 5G core network and a radio access network/access network (RAN/AN). The MA-PDU connection service is implemented by establishing a MA-PDU session (e.g., a PDU session comprising user plane resources on two access networks, such as a 3GPP access network and a non-3 GPP access network). To establish the MA-PDU session, single network slice selection assistance information (S-NSSAI) for the PDU session allows for both 3GPP access networks and non-3 GPP access networks. The UE may request a MA-PDU session when the UE registers through both the 3GPP access network and the non-3 GPP access network, or when the UE registers through either access network. Disclosure of Invention In one aspect of the disclosure, a method includes receiving, by a User Equipment (UE), a first message from a first device of a first access network, the first message including an indication of one or more network nodes of a second access network in a sleep state. The UE determines to wake up a first network node of a second access network from a sleep state and transmits a second message to a first device of the first access network, the second message including a request to wake up the first network node of the second network access network from the sleep state. In one aspect of the method, the UE determines to wake the first network node from a sleep state based on determining to request service from the second access network. In one aspect of the method, the UE determines to wake the first network node from a sleep state based on a voice call request from the second access network. In one aspect of the method, the UE determines to wake the first network node from a sleep state based on determining a change in the first access network. In one aspect of the method, the change in the first access network includes service degradation from the first access network. In one aspect of the method, the method further comprises registering, by the UE, with a first access network and a second access network. In one aspect of the method, the first message includes an indication of at least a first network node of the second access network and a second access node of the second access network. In one aspect of the method, the first network node and the second network node are included in a neighbor cell list. In one aspect of the method, the UE selects a first network node of a second access network to wake up from a sleep state based on the first network node being at the top of a camped cell list. In one aspect of the method, determining that the first network node of the second access network wakes up from the sleep state is based on a location of the first network node relative to the first access network. In one aspect of the disclosure, a method includes receiving, by a first device of a first access network and a second access network, a first message from at least a first network node of the second access network, the first message including an indication that the first network node enters a sleep state. The first means of the first access network and the second access network transmits a second message to the first User Equipment (UE), the second message comprising an indication that the first network node of the second access network enters a sleep state. The first means of the first access network and the second access network receives a third message from the first UE, the third message comprising a request to wake up the first network node of the second network access network from a sleep state, and transmits a fourth message to the first network node of the second access network, the fourth message comprising a wake-up command indicating that the first network node of the second access network changes from the sleep state to the wake-up state. In one aspect of the method, the first message includes information related to one or more UEs associated with the first network node. In one aspect of the method, the information related to the one or more UEs includes information related to the first UE. In one aspect of the method, the method further comprises determining, by the first apparatus, that the first UE is affected by the first networ
