Abstract
The present application relates to a method and apparatus for selecting user plane function. One embodiment of the subject disclosure provides a method for selecting User Plane Function (UPF), comprising: getting, by a Session Management Function (SMF), application information in a Protocol Data Unit (PDU) session during a PDU Session Establishment procedure or during Domain Name System (DNS) Query processing; and selecting, by the SMF, the UPF based on the application information.
Claims13
An apparatus for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the apparatus to:
- receive, by a session management function (SMF), application information in a protocol data unit (PDU) session during domain name system (DNS) query processing, wherein the application information comprises an application identifier for an application;
- receive, by the SMF, policy and charging control (PCC) rules for the PDU session based on the application information;
- select, by the SMF, a user plane function (UPF) based on the application information and the PCC rules;
- receive, by the SMF from a policy control function (PCF), a fully qualified domain name (FQDN), wherein the FQDN is included in packet detection information (PDI) as one or more of a separate parameter or a part of the application information;
- communicate, by the SMF to the UPF, an application detection rule for the application and the FQDN corresponding to the application identifier;
- and
- receive, by the SMF from the UPF, the application identifier based at least in part on the FQDN.
A method performed by an apparatus, the method comprising:
- receiving, by a session management function (SMF), application information in a protocol data unit (PDU) session during domain name system (DNS) query processing, wherein the application information comprises an application identifier for an application;
- receiving, by the SMF, policy and charging control (PCC) rules for the PDU session based on the application information;
- selecting, by the SMF, a user plane function (UPF) based on the application information and the PCC rules;
- receiving, by the SMF from a policy control function (PCF), a fully qualified domain name (FQDN), wherein the FQDN is included in packet detection information (PDI) as one or more of a separate parameter or a part of the application information;
- communicating, by the SMF to the UPF, an application detection rule for the application and the FQDN corresponding to the application identifier;
- and
- receiving, by the SMF from the UPF, the application identifier based at least in part on the FQDN.
