Abstract
Systems, apparatuses, and methods are described for wireless communications. A session management function may provide to a user plane function one or more messages comprising an Ethernet packet filter set and/or information for at least one policy rule. The user plane function may apply the at least one policy rule to a data flow to provide an Ethernet packet data unit session for a wireless device.
Claims24
A method comprising:
- receiving, by a session management function from a wireless device, a first message comprising an Ethernet packet filter set, associated with the wireless device, for establishment of a packet data unit (PDU) session;
- sending, by the session management function to a policy control function, a second message requesting a policy and charging control (PCC) rule, wherein the second message comprises the Ethernet packet filter set;
- receiving, by the session management function from the policy control function, a third message comprising the PCC rule;
- sending, by the session management function to a user plane function, a fourth message comprising:
- the Ethernet packet filter set;
- and
- at least one parameter indicating the PCC rule;
- and
- receiving, by the session management function, a fifth message indicating establishment of the PDU session.
6 more elements
A session management function comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the session management function to:
- receive, from a wireless device, a first message comprising an Ethernet packet filter set, associated with the wireless device, for establishment of a packet data unit (PDU) session;
- send, to a policy control function, a second message requesting a policy and charging control (PCC) rule, wherein the second message comprises the Ethernet packet filter set;
- receive, from the policy control function, a third message comprising the PCC rule;
- send, to a user plane function, a fourth message comprising:
- the Ethernet packet filter set;
- and
- at least one parameter indicating the PCC rule;
- and
- receive a fifth message indicating establishment of the PDU session.
9 more elements
A non-transitory computer-readable medium storing instructions that, when executed, cause:
- receiving, by a session management function from a wireless device, a first message comprising an Ethernet packet filter set, associated with the wireless device, for establishment of a packet data unit (PDU) session;
- sending, by the session management function to a policy control function, a second message requesting a policy and charging control (PCC) rule, wherein the second message comprises the Ethernet packet filter set;
- receiving, by the session management function from the policy control function, a third message comprising the PCC rule;
- sending, by the session management function to a user plane function, a fourth message comprising:
- the Ethernet packet filter set;
- and
- at least one parameter indicating the PCC rule;
- and
- receiving, by the session management function, a fifth message indicating establishment of the PDU session.
6 more elements
A system comprising:
- a session management function;
- a policy control function;
- and
- a user plane function,
- wherein the session management function, perform by a processor couple to a memory, is configured to:
- receive, from a wireless device, a first message comprising an Ethernet packet filter set, associated with the wireless device, for establishment of a packet data unit (PDU) session;
- and
- send, to the policy control function, a second message requesting a policy and charging control (PCC) rule, wherein the second message comprises the Ethernet packet filter set,
- wherein the policy control function, perform by a processor couple to a memory, is configured to:
- send, to the session management function, a third message comprising the PCC rule,
- wherein the session management function, perform by the processor couple to the memory, is further configured to:
- send, to the user plane function, a fourth message comprising:
- the Ethernet packet filter set;
- and
- at least one parameter indicating the PCC rule, and
- wherein the user plane function, perform by a processor couple to a memory, is configured to:
- send, to the session management function, a fifth message indicating establishment of the PDU session.
