Abstract: Systems and methods of a network that implements network slicing. In one embodiment, the system includes an account charging server that determines a plurality of charging rules for a UE that are each mapped to a different network slice of the network, a policy control server that identifies the charging rules, and a slice selection server that selects a network slice for the UE based on the charging rules. The system further includes an interface between the policy control server and the account charging server that supports a transaction based on Diameter protocol that includes a request/response. A first Attribute Value Pair (AVP) is defined for the response to identify a charging rule, and a second AVP is defined for the response to identify a network slice that is mapped to the charging rule.

Abstract: Systems, methods, and software for selecting a network slice for User Equipment (UE) in a network that is partitioned into network slices. In one embodiment, a slice selection server receives an attach request intiated by the UE to attach to the network, sends a request to a policy control server to obtain a slice selection policy for the UE, and receives a response from the policy control server indicating a plurality of charging rules for the UE that are each mapped to a different one of the network slices. The slice selection server selects a network slice for the UE based on the charging rules, and sends an attach response to the UE that includes a network slice identifier (ID) for the network slice selected for the UE.
