Abstract

Techniques, devices, and systems for implementing a Priority Data Transport Service (PDTS) are disclosed. The PDTS provides authorized devices and/or authorized users with on-demand, priority data transport (e.g., priority Internet access). For example, the PDTS allows authorized devices and/or authorized users to access the Internet, use mobile applications, and/or send and receive image data, video data, and text data in a prioritized manner, as compared to the regular (non-priority) Internet access that is provided to non-subscribers of the PDTS over commercial telecommunications networks. An authorized user may activate and deactivate the PDTS on demand. For instance, the PDTS may be activated during an emergency or crisis situation when networks may be congested, thereby providing the user with priority data transport (e.g., priority Internet access) in an emergency or crisis situation when a telecommunications network may be overloaded.

Claims17

Dependent claims

A user equipment (UE) comprising:

a processor;
and
memory storing a first set of UE route selection policy (URSP) rules and computer-executable instructions that, when executed by the processor, cause the UE to:
register for a first network slice and a second network slice, wherein the second network slice is configured to provide higher priority transport of data packets during protocol data unit (PDU) sessions than the first network slice;
receive user input to activate a priority data transport service (PDTS);
send a PDU session establishment request;
receive, based at least in part on the PDU session establishment request, a second set of URSP rules;
delete the first set of URSP rules from the memory at a time of receiving the second set of URSP rules;
send, based at least in part on a URSP rule of the second set of URSP rules, one or more data packets during a PDU session via at least one of:
the second network slice;
or
a third network slice that is configured to provide higher priority transport of data packets during PDU sessions than the first network slice;
receive second user input to deactivate the PDTS;
send a second PDU session establishment request;
receive, based at least in part on the second PDU session establishment request, the first set of URSP rules to replace the second set of URSP rules in the memory;
and
send, based at least in part on a URSP rule of the first set of URSP rules, one or more second data packets during a second PDU session via the first network slice.

14 more elements

A method comprising:

based on a first set of user equipment route selection policy (URSP) rules stored in memory of a user equipment (UE), registering, by the UE, for a first network slice and a second network slice, wherein the second network slice is configured to provide higher priority transport of data packets during protocol data unit (PDU) sessions than the first network slice;
receiving, by the UE, user input to activate a priority data transport service (PDTS), wherein the UE is not subscribed to the PDTS, the second network slice is usable by UEs that are not subscribed to the PDTS to activate the PDTS, and the user input corresponds to navigating a browser to a site;
sending, by the UE and based at least in part on a URSP rule of the first set of URSP rules, a PDU session establishment request via the second network slice;
receiving, during an intermediate PDU session, second user input corresponding to credentials entered by a user of the UE via the site;
after sending the PDU session establishment request and after receiving the second user input, receiving, by the UE, based at least in part on the PDU session establishment request, a second set of URSP rules;
and
sending, by the UE, based at least in part on a URSP rule of the second set of URSP rules, one or more data packets during a PDU session via
a third network slice that is configured to provide higher priority transport of data packets during PDU sessions than the first network slice.

5 more elements

A method comprising:

registering a user equipment (UE) for a first network slice and a second network slice, wherein the second network slice is configured to provide higher priority transport of data packets during protocol data unit (PDU) sessions than the first network slice;
receiving, from the UE, a PDU session establishment request via the second network slice, the PDU session establishment request being associated with activation of a priority data transport service (PDTS);
based on the PDU session establishment request, sending, to the UE, a first set of UE route selection policy (URSP) rules, wherein the first set of URSP rules replaces a second set of URSP rules in memory of the UE;
routing one or more data packets associated with a PDU session involving the UE via at least one of:
the second network slice;
or
a third network slice that is configured to provide higher priority transport of data packets during PDU sessions than the first network slice;
receiving, from the UE, a second PDU session establishment request associated with deactivation of the PDTS;
sending, based at least in part on the second PDU session establishment request, the second set of URSP rules to replace the first set of URSP rules in the memory;
and
routing, based at least in part on a URSP rule of the second set of URSP rules, one or more second data packets during a second PDU session via the first network slice.
