[0067] The first embodiment of the present invention is described below. In the first embodiment, the PCEF of the visited network initiates the establishment of a bearer with the PCEF of the user's home network. FIG. 2 is a schematic flowchart of an exemplary policy and charging control method in a user roaming state according to a first embodiment of the present invention. As shown in Figure 2, the method includes:

[0068]Step 201: The AF acquires service information of the UE, where the service information is preferably related to session parameter negotiation at the communication peer, and sends the service information to the PCRF of the user's home network.

[0069] Step 202: The PCRF of the user's home network stores the received service-related information as a basis for subsequently formulating policies and charging control rules, and returns a confirmation message to the AF.

[0070] Step 203: The PCRF of the user's home network generates the information required to ...

Abstract

This invention discloses a strategy and billing control method in the state of users' roaming, including: AF accesses UE business information and sends to PCRF of user attaching network, and PCRF generates the information needed in setting the strategy and billing control rules according to it and sends to PCRF of the visit network. According to the information sent from PCRF of user attaching network, PCRF of the visit network set the rules of strategy and billing control, and sends to PCEF.

Description

technical field [0001] The present invention relates to the field of wireless communication, and more specifically, relates to a strategy and charging control method in the state of user roaming. Background technique [0002] In the 3rd Generation Partnership Project (3GPP), the implementation of Internet Protocol (IP) Flow Based Charging (FBC, Flow Based Charging) is discussed. For a packet data service, the amount of data consumed by a user when using the service is called a service data flow (Service DataFlow), and a service data flow is a collection of multiple IP flows. However, multiple different services can be carried in one PDP context (context), so the granularity of IP flow-based charging is much smaller than that of PDP context-based charging, thus providing operators or service providers with richer services. means of billing. [0003] According to the current 3GPP's division of functional entities for implementing FBC, the TPF bears IP data streams. When the ...
