Mechanisms for establishing user plane connectivity for non-3GPP access
First Claim
1. A method for wireless communication, comprising:
- receiving, at a wireless device in a connection management (CM) idle state for both a first radio access technology (RAT) and a second RAT, a paging request over the first RAT; and
initiating a user plane establishment procedure in response to the paging request, comprising;
in response to the paging request that was received over the first RAT at the wireless device in the CM idle state for both the first RAT and the second RAT, transmitting a service request message over the first RAT, the service request comprising a list of protocol data unit (PDU) sessions wherein the list of PDU sessions indicates one or more PDU sessions for which a user plane cannot be established over the first RAT.

Abstract
Methods, systems, and devices for wireless communication are described. A wireless device transmits an indication of whether the device should be paged over a 3GPP access when a core network has data ready to transmit for PDU sessions over a non-3GPP access. A session management function (SMF) of the core network receives a data notification indicating that the core network has data ready to transmit to the wireless device for a PDU session over the non-3GPP access. The SMF determines whether to transmit a paging request to an access and mobility management function (AMF) of the core network based on a paging state of the SMG, a paging state of the wireless device, or a connection management idleness state of the wireless device. The AMF determines whether to transmit a paging message to the wireless device.

13. An apparatus for wireless communication, in a system comprising:
-
a processor; memory in electronic communication with the processor; and instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to; receive, at a wireless device in a connection management (CM) idle state for both a first radio access technology (RAT) and a second RAT, a paging request over the first RAT; and initiate a user plane establishment procedure in response to the paging request, comprising; in response to the paging request that was received over the first RAT at the wireless device in the CM idle state for both the first RAT and the second RAT, transmitting a service request message over the first RAT, the service request comprising a list of protocol data unit (PDU) sessions wherein the list of PDU sessions indicates one or more PDU sessions for which a user plane cannot be established over the first RAT. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. An apparatus for wireless communication, comprising:
-
means for receiving, at a wireless device in a connection management (CM) idle state for both a first radio access technology (RAT) and a second RAT, a paging request over the first RAT; and means for initiating a user plane establishment procedure in response to the paging request, comprising; means for, in response to the paging request that was received over the first RAT at the wireless device in the CM idle state for both the first RAT and the second RAT, transmitting a service request message over the first RAT, the service request comprising a list of protocol data unit (PDU) sessions wherein the list of PDU sessions indicates one or more PDU sessions for which a user plane cannot be established over the first RAT. - View Dependent Claims (21, 22)
