Abstract
A control plane entity selects a subset of a plurality of user plane entities to support a charging session associated with a user based on charging policies for the plurality of user plane entities. The control plane entity allocates portions of a quota for the charging session to the control plane entity and the subset of the plurality of user plane entities based on the charging policies. In some cases, the control plane entity modifies the quotas that are allocated to the control plane entity or the subset of the plurality of user plane entities. Modifying the quotas can include redistributing unused portions of the quotas among the control plane entity and the subset of the plurality of user plane entities, e.g., in response to handover of the user equipment between user plane entities.
