Abstract

This disclosure relates to techniques for selecting an access for transmitting messages on a 5G network. An access may be selected based on determined conditions in relation to one or more network policies and a message may be transmitted on the selected access.

First claim

What is claimed is:

1 . A method, comprising:
by a first device:
registering a user equipment device (UE) with a public land mobile network (PLMN) using a 3GPP access;
registering the UE with the PLMN using a non-3GPP access;
detecting a cause to deregister the UE with the PLMN;
in response to detecting the cause to deregister the UE with the PLMN, determining one or more conditions related to deregistering the UE with the PLMN;
selecting, based at least in part on the one or more conditions, a selected access to perform the deregistering; and
transmitting, on the selected access, a deregistration message.

2 . The method of claim 1 , wherein the one or more conditions includes a connection state of at least a first access, wherein the first access is one of the 3GPP access or the non-3GPP access.

3 . The method of claim 2 ,
wherein the connection state of the first access is connected, wherein the selected access is the first access.

4 . The method of claim 1 , wherein the one or more conditions includes a connection state of the 3GPP access and a connection state of the non-3GPP access.

5 . The method of claim 4 ,
wherein the connection state of the 3GPP access is connected, wherein the connection state of the non-3GPP access is connected, wherein the selected access is the 3GPP access.

6 . The method of claim 4 ,
wherein the connection state of the 3GPP access is idle, wherein the connection state of the non-3GPP access is idle, wherein the selected access is the 3GPP access.

7 . The method of claim 1 ,
wherein the one or more conditions includes that the deregistration is for a single access, wherein the selected access is the single access.

8 . The method of claim 1 ,
wherein the first device is the UE.

9 . The method of claim 1 ,
wherein the first device is a network element of the PLMN.

10 . A method, comprising:
by a network element of a 5G network:
establishing a 3GPP access with a wireless device;
establishing a non-3GPP access with the wireless device;
determining a message for the wireless device;
determining a type of the message;
in response to determining the type of the message for the wireless device, determining at least one condition to evaluate;
evaluating the at least one condition;
selecting, based on the evaluation of the at least one condition, a selected access, wherein the selected access is one of the 3GPP access and the non-3GPP access; and
sending the message on the selected access.

11 . The method of claim 10 ,
wherein the at least one condition includes a connection status of at least one of the 3GPP access or non-3GPP access.

12 . The method of claim 10 ,
wherein the message includes an indication that downlink signaling or user data is pending for the wireless device, wherein the at least one condition includes a service type associated with the downlink signaling or user data.

13 . The method of claim 10 ,
wherein the at least one condition includes information about past communications.

14 . The method of claim 10 ,
wherein the at least one condition includes timing information.

15 . The method of claim 10 ,
wherein the at least one condition includes an attribute of the wireless device.

16 . The method of claim 10 ,
wherein the at least one condition includes a policy of the 5G network.

17 . An apparatus comprising:
a processor, wherein the processor is configured to cause a network element of a 5G network to:
establish at least two accesses with a wireless device;
determine a first message for the wireless device;
in response to determining the first message for the wireless device, determine at least one condition, wherein the at least one condition is based at least in part on a network policy;
evaluate the at least one condition;
select, based on the at least one condition, a selected access, wherein the selected access is one of the at least two accesses; and
send the first message on the selected access.

18 . The apparatus of claim 17 , wherein the processor is further configured to cause the network element of the 5G network to:
determine that a first response to the first message has been received; and determine a type of the first response.

19 . The apparatus of claim 19 , wherein the type of the first response is a failure response, wherein the processor is further configured to cause the network element of the 5G network to:
deliver, in response to the failure response, data to the UE on the selected access.

20 . The apparatus of claim 17 , wherein the processor is further configured to cause the network element of the 5G network to:
determine that no response to the first message has been received; and switch, based on determining that no response has been received, to a second access and transmit the message on the second access.
