Title:
SUPPORTING MULTIPLE QOS FLOWS FOR UNSTRUCTURED PDU SESSIONS IN WIRELESS SYSTEM USING NON-STANDARDIZED APPLICATION INFORMATION
Document Type and Number:
WIPO Patent Application WO/2019/158083
Kind Code:
A1
Abstract:
A method in a session management function (SMF) of a network. The method comprises: receiving a session request message from a user equipment (UE), the session request message comprising: an identifier of the UE; a UE-specific application identifier that uniquely identifies a particular application among a set of one or more applications implemented on the UE; and an application-specific packet filter set identifier that uniquely identifies a particular packet filter set among a group of one or more packet filter sets supported by the particular application. A protocol data unit (PDU) session is established based at least in part on the identifier of the UE, the UE-specific application identifier, and the application-specific packet filter set identifier.
