System and method for ephemeral assignment of network slices

A method comprising:

• sending, by a device, an enlistment request to a network over a wireless connection, wherein the enlistment request includes an application identifier (ID) corresponding to an application to be enlisted;
• receiving a reply from the network in response to the enlistment request, wherein the reply includes a replacement User Equipment Route Selection Policy (URSP) rule;
• receiving a session request from the application to establish a session;
• identifying, in response to the session request and based on the replacement URSP rule, a network slice on the network;
• establishing the session between the application and the identified network slice on the network;
• and
• restoring a database, which is hosted on the device, that includes URSP rules to a state prior to sending the enlistment request to the network, wherein restoring the database to the state prior to sending the enlistment request includes:
• removing the replacement URSP rule from the database;
• and inserting, in the database, a prior URSP rule, if any, that was overwritten by the replacement URSP rule after receiving the reply from the network.

A non-transitory computer-readable medium comprising processor-executable instructions, which when executed by a processor of included in a device, cause the processor to:

• send an enlistment request to a network over a wireless connection, wherein the enlistment request includes an application identifier (ID) corresponding to an application to be enlisted;
• receive a reply from the network in response to the enlistment request, wherein the reply includes a replacement User Equipment Route Selection Policy (URSP) rule;
• receive a session request from the application to establish a session;
• identify, in response to the session request and based on the replacement URSP rule, a network slice on the network;
• establish the session between the application and the identified network slice on the network;
• and
• restore a database, which is hosted on the device, that includes URSP rules to a state prior to sending the enlistment request to the network, wherein when the processor restores the database, the processor is to:
• remove the replacement URSP rule from the database;
• and
• insert, in the database, a prior URSP rule, if any, that was overwritten by the replacement URSP rule after the processor received the reply from the network.
