Abstract

A user equipment (UE) modem stores a route selection policy (URSP), the URSP associating each of a plurality of data network name (DNN) identifiers and a corresponding slice, wherein a first DNN identifier (ID) is associated with a first DNN and a first slice and a second DNN ID is associated with the first DNN and a second slice different than the first slice. The modem establishes a first protocol data unit (PDU) session with the first DNN and the first slice in response to receiving a first indication to start a first network interface associated with the first DNN ID. The modem establishes a second PDU session with the first DNN and the second slice in response to receiving a second indication to start a second network interface associated with the second DNN ID.

First claim

What is claimed is:

1. A method of wireless communication at a user equipment (UE), comprising:
storing, by a modem, a UE route selection policy (URSP), the URSP associating each of a plurality of data network name (DNN) identifiers and a corresponding slice, wherein a first DNN identifier (ID) is associated with a first DNN and a first slice and a second DNN ID is associated with the first DNN and a second slice different than the first slice;
establishing a first protocol data unit (PDU) session with the first DNN and the first slice in response to receiving a first indication to start a first network interface associated with the first DNN ID;
validating an application to use the second DNN ID; and
establishing a second PDU session with the first DNN and the second slice, after validating the application to use the second DNN ID, in response to receiving a second indication initiated by the application and indicating to start a second network interface associated with the second DNN ID.

2. The method of claim 1 , further comprising:
receiving the second indication to start the second network interface, wherein the second indication includes the second DNN ID and service information, wherein the modem validates the application to use the second DNN ID using the URSP and the service information.

3. The method of claim 2 , wherein the service information includes one or more parameters comprising:
an operating system identifier,
an application identifier,
remote Internet Protocol version 4 (IPv4) information,
an IPv4 address mask,
remote internet protocol version 6 (IPv6) information,
an IPv6 prefix length,
a remote fully qualified domain name (FQDN),
a destination port,
a destination port range,
a destination port range lower limit,
a destination port range higher limit,
a destination medium access control (MAC) address for non-internet protocol packets,
a virtual local area network identifier (VID) of a customer virtual local area network (VLAN) tag, or
a VID of a service VLAN tag.

4. The method of claim 2 , wherein the modem validates the application to use the second DNN ID using the URSP and an application identifier comprised in the service information.

5. The method of claim 1 , wherein the first slice is an enhanced Mobile Broadband (eMBB) slice.

6. The method of claim 5 , wherein the second slice is an Ultra-Reliable Low Latency Communications (URLLC) slice, a massive Internet of Things (MIoT) slice, or an operator defined proprietary slice.

7. The method of claim 1 , wherein the first slice is an Ultra-Reliable Low Latent Communications (URLLC) slice and the second slice is an enhanced Mobile Broadband (eMBB) slice, a massive Internet of Things (MIoT) slice, or an operator defined proprietary slice.

8. The method of claim 1 , wherein the first slice is a massive Internet of Things (MIoT) slice and the second slice is an enhanced Mobile Broadband (eMBB) slice, an URLLC slice, or an operator defined proprietary slice.

9. A method of wireless communication at a user equipment (UE), comprising:
storing, by a modem, a UE route selection policy (URSP), the URSP associating each of a plurality of data network name (DNN) identifiers and a corresponding slice, wherein a first DNN identifier (ID) is associated with a first DNN and a first slice and a second DNN ID is associated with the first DNN and a second slice different than the first slice;
establishing a first protocol data unit (PDU) session with the first DNN and the first slice in response to receiving a first indication to start a first network interface associated with the first DNN ID;
sending, from an application to an operating system, a network request application programming interface (API) comprising the second DNN ID and service information; and
establishing a second PDU session with the first DNN and the second slice in response to receiving a second indication to start a second network interface associated with the second DNN ID.

10. The method of claim 9 , further comprising:
in response to receiving the network request API at the operating system from the application, passing a network request and the service information to a radio interface layer (RIL); and
adding a new entry in an access point name (APN) context table.

11. The method of claim 10 , further comprising:
determining, at the RIL, to establish a new interface based on the second DNN ID being a new identifier without a previously established interface; and
sending, from the RIL to the modem, the second indication to start the second network interface associated with the second DNN ID, wherein the second indication comprises the service information.

12. An apparatus for wireless communication at a user equipment (UE), comprising:
a memory; and
at least one processor coupled to the memory, wherein the memory and the at least one processor are configured to:
store, by a modem, a UE route selection policy (URSP), the URSP associating each of a plurality of data network name (DNN) identifiers and a corresponding slice, wherein a first DNN identifier (ID) is associated with a first DNN and a first slice and a second DNN ID is associated with the first DNN and a second slice different than the first slice;
establish a first protocol data unit (PDU) session with the first DNN and the first slice in response to receiving a first indication to start a first network interface associated with the first DNN ID;
validate an application to use the second DNN ID; and
establish a second PDU session with the first DNN and the second slice, after validation of the application to use the second DNN ID, in response to receiving a second indication initiated by the application and indicating to start a second network interface associated with the second DNN ID.

13. The apparatus of claim 12 , wherein the memory and the at least one processor are further configured to:
receive the second indication to start the second network interface, wherein the second indication includes the second DNN ID and service information, wherein the modem is configured to validate the application to use the second DNN ID using the URSP and the service information.

14. The apparatus of claim 13 , wherein the service information includes one or more parameters comprising:
an operating system identifier,
an application identifier,
remote Internet Protocol version 4 (IPv4) information,
an IPv4 address mask,
remote internet protocol version 6 (IPv6) information,
an IPv6 prefix length,
a remote fully qualified domain name (FQDN),
a destination port,
a destination port range,
a destination port range lower limit,
a destination port range higher limit,
a destination medium access control (MAC) address for non-internet protocol packets,
a virtual local area network identifier (VID) of a customer virtual local area network (VLAN) tag, or
a VID of a service VLAN tag.

15. The apparatus of claim 13 , wherein the modem is configured to validate the application to use the second DNN ID using the URSP and an application identifier comprised in the service information.

16. The apparatus of claim 12 , wherein the first slice is an enhanced Mobile Broadband (eMBB) slice.

17. The apparatus of claim 16 , wherein the second slice is an Ultra-Reliable Low Latency Communications (URLLC) slice, a massive Internet of Things (MIoT) slice, or an operator defined proprietary slice.
