Methods and apparatuses for data transmission. A method implemented at a first network function may comprise obtaining information related to network slice selection; and sending a reroute message to an access network node, wherein the reroute message including a container comprising at least one information element of the information related to network slicing selection.

Systems and methods are provided for utilizing an asynchronous report feature when a time or volume reporting trigger is unavailable. The systems and method can include receiving node level capabilities from at least one of a plurality of user plane functions, receiving an asynchronous report from the at least one of the plurality of user plane functions, determining an absence of a reporting trigger based on charging information associated with a policy control function and trigger information associated with a charging function, selecting a user plane function from the plurality of user plane functions based on the asynchronous report, and generating a usage reporting rule without the reporting trigger to be provided to the user plane function from the plurality of user plane functions.

A control plane function node may be used in a Fifth Generation (5G) Non-Standalone (NSA) architecture having Radio Access Network (RAN) level interworking between a Long-Term Evolution (LTE) RAN and a 5G New Radio (NR). The node obtains usage report data which are based on traffic of a user equipment (UE) via primary and secondary Radio Access Technologies (RATs). The node also obtains secondary RAT usage report data which are based on traffic of the UE via the secondary RAT. The node constructs a message which indicates a request for charging based on the usage report data and the secondary RAT usage report data. In constructing the message, the node populates, in association with a corresponding rating group and usage data of the UE, an identifier of a flow or bearer associated with secondary RAT usage, together with the secondary RAT usage report data.

Device group partitions and a settlement platform are provided. In some embodiments, device group partitions (e.g., partitions of devices based on associated device groups) are provided. In some embodiments, a settlement platform service is provided. In some embodiments, a settlement platform service is provided for partitioned devices. In some embodiments, collecting device generated service usage information for one or more devices in wireless communication on a wireless network; and aggregating the device generated service usage information for a settlement platform for the one or more devices in wireless communication on the wireless network is provided. In some embodiments, a settlement platform implements a service billing allocation and/or a service/transactional revenue share among one or more partners. In some embodiments, service usage information includes micro-CDRs, which are used for CDR mediation or reconciliation that provides for service usage accounting on any device activity that is desired. In some embodiments, each device activity that is desired to be associated with a billing event is assigned a micro-CDR transaction code, and a service processor of the device is programmed to account for that activity associated with that transaction code. In some embodiments, a service processor executing on a wireless communications device periodically reports (e.g., during each heartbeat or based on any other periodic, push, and/or pull communication technique(s)) micro-CDR usage measures to, for example, a service controller or some other network element for CDR mediation or reconciliation.

A session management function (SMF) sends to a charging function (CHF), a charging policy request message requesting charging policy information for a packet data unit (PDU) session of a wireless device. The SMF receives, by from the CHF, a response message comprising the charging policy information for the PDU session. The charging policy information comprises: a first charging method; and an information element indicating that a first charging rate is applicable for the PDU session. The SMF determines, based on the charging policy information, a charging control rule for the PDU session. The SMF enforces the charging control rule.

A policy transmission method, a policy control function (PCF) network element, and a computer storage medium, where the method includes: obtaining, by a PCF network element, a connection management state of a terminal apparatus, where the connection management state includes a connected mode or an idle mode; and sending, by the PCF network element, policy rule information to the terminal apparatus when the connection management state of the terminal apparatus is the connected mode.

A Policy Control Function, PCF, for use in a 5G core network, is configured to allow a consumer to retrieve from the PCF subscriber session information and Application Detection and Control rules relating to a subscriber session. Specifically, the PCF is configured to: receive (303) a request from a Session Management Function, SMF, for session management policies applying to the subscriber session; retrieve (305) policy data from a Unified Data Repository, UDR; and, based on the retrieved policy data, generate said Application Detection and Control rules relating to the subscriber session, and send (307) said Application Detection and Control rules to the TDF, thereby allowing the TDF to act as the consumer.

Methods and apparatus for traffic enhancement to apply to an application, to be delivered using a QUIC session, between a wireless device and a server. A request to activate a policy for the application between the wireless device and the server is received from the wireless device, the request including an application identifier and an indication to request an enhancement function. In response to the request to activate the policy, an authorization of traffic enhancement with information of a proxy node is transmitted to the wireless device to provide the enhancement function upon the network node identifying the proxy node.

Provided are a method and apparatus for providing a policy of a user equipment in a wireless communication system, and an operating method of a visited-policy control function (V-PCF) of a visited public land mobile network (PLMN) providing a policy for processing traffic of a user equipment in a wireless communication system, the operating method includes: transmitting an indicator requesting transmission or allowance of transmission of a visited user equipment route selection policy (V-URSP) of the V-PCF to a home-policy control function (H-PCF) of a home PLMN; receiving, from the H-PCF, an indicator indicating whether transmission of the V-URSP of the V-PCF is allowed; and receiving a home user equipment route selection policy (H-URSP) from the H-PCF.

In one aspect, a device, operating in an access network that can provide a plurality of QoS levels for user data flowing to and from the device, establishes a packet data session via the access network and receives, from the access network, cost information associated with each of one or more QoS levels. The device selects, for user data for at least a first application or service, a QoS level from among the plurality of QoS levels based on the cost information. The device transmits packets carrying user data for the first application or service to the access network. The transmission includes applying a QoS treatment to the user data according to the selected QoS level.
