Methods, system, UE, PGW-U and MME for managing traffic differentiation

A method, performed by a User Equipment (UE), for enabling differentiation of traffic transmittable by the UE, wherein the method comprises:

• transmitting, by the UE toward a Mobility Management Entity (MME), a request for a marking type and a marking value, which originate from a Service Capability Server/Application Server (SCS/AS) and which are associated with a software application identifier for identifying software application traffic to be handled according to the marking type and the marking value, such that:
• the request is transmitted by the MME,
• the marking type and the marking value for the software application identifier are received by the MME,
• the marking type and the marking value are transmitted by the MME toward the UE,
• receiving, from the MME, the marking type and the marking value, and
• transmitting, towards a Packet GateWay User plane function (PGW-U), the software application traffic marked according to the marking type and the marking value.

A system, comprising a User Equipment (UE), a Packet GateWay User plane function (PGW-U), a Mobility Management Entity (MME), and a Service Capability Server/Application Server (SCS/AS), configured for managing traffic transmitted by the UE, wherein the traffic is associated with a set of Packet Flow Description (PFD) related parameters, wherein

• the UE comprising one or more processors configured for transmitting, toward the MME, a request for a marking type and a marking value, which are associated with a software application identifier for identifying software application traffic to be handled according to the marking type and the marking value,
• the MME comprising one or more processors configured for:
• transmitting the request,
• receiving the marking type and the marking value for the software identifier;
• the SCS/AS comprising one or more processors configured for transmitting the marking type and the marking value,
• the PGW-U comprising one or more processors configured for receiving the marking type and the marking value, which originate from the SCS/AS,
• the MME comprising one or more processors configured for transmitting, towards the UE, the marking type and the marking value, which originate from the SCS/AS and which are associated with the software application identifier,
• the UE comprising one or more processors configured for receiving, from the MME, the marking type and the marking value, which originate from the SCS/AS and which are associated with the software application identifier,
• the UE comprising one or more processors configured for transmitting towards the PGW-U, the software application traffic marked according to the marking type and the marking value,
• the PGW-U comprising one or more processors configured for receiving the software application traffic from the UE,
• the PGW-U comprising one or more processors configured for inspecting the software application traffic according to the marking type to obtain the marking value, and
• the PGW-U comprising one or more processors configured for handling the software application traffic based on the marking value.

A User Equipment (UE) comprising a processing circuit configured for enabling differentiation of traffic transmittable by the UE, wherein the UE comprises one or more processors configured for:

• transmitting, by the UE toward a Mobility Management Entity (MME), a request for a marking type and a marking value, which originate from a Service Capability Server/Application Server (SCS/AS) and which are associated with a software application identifier for identifying software application traffic to be handled according to the marking type and the marking value, such that:
• the request is transmitted by the MME,
• the marking type and the marking value for the software application identifier are by the MME,
• the marking type and the marking value are transmitted by the MME toward the UE,
• receiving, from the MME, the marking type and the marking value, and
• transmitting, toward a Packet GateWay User plane function (PGW-U), the software application traffic marked according to the marking type and the marking value.

A Packet GateWay User plane function (PGW-U) comprising a processing circuit configured for managing traffic transmitted by a User Equipment (UE), wherein the traffic is associated with a set of Packet Flow Description (PFD) related parameters, wherein the PGW-U comprises one or more processors configured for:

• receiving a marking type and a marking value, which originate from a Service Capability Server/Application Server (SCS/AS) and which are associated with a software application identifier for identifying software application traffic to be handled according to the marking type and the marking value, such that:
• a request for the marking type and the marking value is transmitted by a Mobility Management Entity (MME),
• the marking type and the marking value for the software application identifier are received by the MME,
• the marking type and the marking value are transmitted by the MME toward the UE,
• receiving the software application traffic from the UE,
• inspecting the software application traffic according to the marking type to obtain the marking value, and

A Mobility Management Entity (MME) comprising a processing circuit configured for enabling differentiation of traffic transmittable by a User Equipment (UE), wherein the MME comprises one or more processors configured for:

• receiving, from the UE, a request for a marking type and a marking value, which originate from a Service Capability Server/Application Server (SCS/AS) and which are associated with a software application identifier for identifying software application traffic to be handled according to the marking type and the marking value, such that:
• the marking type and the marking value for the software application identifier are transmitted by a Packet GateWay Control plane function (PGW-C), toward the MME,
• the marking type and the marking value are transmitted by the MME toward the UE,
• transmitting, toward the PGW-C, the request:
• receiving, by the MME, the marking type and the marking value, and
