Policy and charging control method, network entities, communication system and computer program therefor

摘要

It is provided a policy and charging control method carried out in a communication network. The communication network comprises a first network entity (100), PCFR, including a policy and charging rules function and a second network entity (200), PCEF, including a policy and charging enforcement function for enforcing policy and charging rules in at least two groups of cells, each group of cells including at least one cell. The method comprises configuring (S110), on the second network entity, for a first one group of the at least two groups of cells, an event subscription dependent on a location of the user equipment, the event subscription being specific to the first group of cells. The method further foresees, at the second network entity, detecting (S120) an event associated with the configured event subscription and sending a notification of the detected event to the first network entity and, at the first network entity, after receipt of the notification, determining (S130) whether to perform one among installing, modifying and removing a policy and charging control rule in dependence of the detected event. Corresponding network entities, network system and computer programs are provided.

1. A policy and charging control method carried out in a communication network, the communication network comprising a first network entity, PCRF, including a policy and charging rules function and a second network entity, PCEF, including a policy and charging enforcement function to enforce policy and charging rules in at least two groups of cells, each group of cells including at least one cell, the method comprising:
configuring, on the second network entity, for a first group of the at least two groups of cells, an event subscription dependent on a location of the user equipment, the event subscription being specific to the first group of cells; at the second network entity, detecting an event associated with the configured event subscription and sending a notification of the detected event to the first network entity; at the first network entity, after receipt of the notification, determining whether to perform one among installing, modifying and removing a policy and charging control rule in dependence of the detected event, wherein the event subscription further depends on at least a user profile associated to a user of the user equipment, wherein the user profile indicates areas defined for the user of the user equipment, and wherein at least one area in the user profile corresponds to the first group of cells.
