Abstract
Systems, apparatuses, and methods are described for wireless communications. Network slicing may be used to provide services for a wireless device. A network slice may be used for a wireless device based on a network entity located in a home public land mobile network (PLMN) or in a visited PLMN.
Claims21
A method comprising:
- receiving, by a visited policy control function and from a first home network entity, a first message indicating a request for a network slice for a wireless device, wherein the first message comprises:
- a third party charging indication;
- and
- a charging policy;
- generating, based on the first message, a network slice identifier for the network slice;
- and
- sending, by the visited policy control function and to a visited session management function, a second message indicating a request to establish the network slice for the wireless device, wherein the second message comprises:
- the network slice identifier;
- the third party charging indication;
- and
- the charging policy.
8 more elements
A visited policy control function comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the visited policy control function to:
- receive, from a first home network entity, a first message indicating a request for a network slice for a wireless device, wherein the first message comprises:
- a third party charging indication;
- and
- a charging policy;
- generate, based on the first message, a network slice identifier for the network slice;
- and
- send, to a visited session management function, a second message indicating a request to establish the network slice for the wireless device, wherein the second message comprises:
- the network slice identifier;
- the third party charging indication;
- and
- the charging policy.
11 more elements
A system comprising:
- a first home network entity;
- a visited policy control function;
- and
- a visited session management function,
- wherein the first home network entity is configured to:
- send, to the visited policy control function, a first message indicating a request for a network slice for a wireless device, wherein the first message comprises:
- a third party charging indication;
- and
- a charging policy, and
- wherein the visited policy control function is configured to:
- generate, based on the first message, a network slice identifier for the network slice;
- and
- send, to the visited session management function, a second message indicating a request to establish the network slice for the wireless device, wherein the second message comprises:
- the network slice identifier;
- the third party charging indication;
- and
- the charging policy.
