Problems solved by technology

[0017] According to the above process, it can be seen that the IP-CAN session modification process initiated by the existing PCRF has at least the following problems: 1) Usually, when the authorization of the business PCC rules in the IP-CAN session modification process fails, there is no contract related If the business or the PCC rejects the business after detection, the PCRF simply sends a message to the GW that the authorization request fails. In this way, the user's session will be simply rejected, so that the business cannot be redirected to the GW. The user displays a reminder, and it is impossible for the GW to redirect the user's session to other servers
[0018] 2) After the session is successfully established, if for some reason, such as the user's subscription amount reaches the contracted value, local timing information triggers, etc., the user session needs to be redirected, that is, the user's session is redirected to another server , in order to display prompts for the user’s subsequent operations such as renewal, etc., no one has proposed a relevant redirection implementation scheme so far

Embodiment 1

[0052] In this embodiment, the redirection list is set on the PCEF in the GW. The triggering reason for the redirection is: the redirection triggered by the PCRF based on the service information caused by the PCC rule authorization failure. Specifically, because the current user service subscription information is not In the obtained user subscription information, or the local policy decision of the PCRF is not authorized to use, so that the PCC rule authorization fails.

[0053] The redirection method based on policy and charging control in this embodiment is as follows Figure 4 shown, including the following steps:

[0054] Step 400: Set the correspondence between the redirection list and the indication information;

[0055] Here, the redirection list is set on the PCEF; and, this step is usually completed at system startup.

[0056] Step 401: the AF sends a user service request message to the PCRF, and the PCRF stores the user service information and returns a user servi...

Embodiment 2

[0064] In this embodiment, the redirection list is set on the PCEF in the GW, and the triggering reason for the redirection is: triggering based on a PCRF local policy, ie: satisfying a preset triggering condition.

[0065] The redirection method based on policy and charging control in this embodiment is as follows Figure 5 shown, including the following steps:

[0066] Step 500: Set the correspondence between the redirection list and the instruction information;

[0067] Here, the redirection list is set on the PCEF; and, this step is usually completed at system startup.

[0068] Step 501: A user IP-CAN session based on a service request is successfully established between the user and the AF;

[0069] Step 502: PCRF detects that a local preset condition is triggered, such as reaching a preset time point, PCRF triggers PCC policy re-decision, and redirects the user IP-CAN session;

[0070] Step 503: PCRF sends a re-authentication authorization request message Diameter RAR...

Embodiment 3

[0075] In this embodiment, the redirection list is set on the PCEF in the GW, and the triggering reason for the redirection is: based on event information, that is, a specified trigger event is generated when a preset condition is met.

[0076] The redirection method based on policy and charging control in this embodiment is as follows Image 6 shown, including the following steps:

[0077] Step 600: Set the correspondence between the redirection list and the indication information;

[0078] Here, the redirection list is set on the PCEF; and, this step is usually completed at system startup.

[0079] Step 601: An IP-CAN session is successfully established between the user and the AF, and the PCRF sets an event trigger (Event Trigger) for the PCEF;

[0080] Here, the event trigger is: to collect statistics on the user's usage for a certain period of time, and to report when the usage reaches a certain preset threshold value, that is, to trigger an event.

[0081] Step 602: PCE...

Abstract

The invention discloses a policy and charging control-based redirection method. In the method, correspondence between a redirection list and indication information is set. The method also comprises the following steps of: a policy control and charging rules function (PCRF) entity transmits the indication information corresponding to a redirection server to a gateway (GW) / policy and charging enforcement function (PCEF) entity when detecting that user session needs to be redirected; and the GW / PCEF determines an address of the redirection server according to the received indication information and a local redirection list and redirects the user session to be directed to a server corresponding to the address. The invention also discloses a policy and charging control-based redirection device. By using the method and the device, the redirection of the user session can be realized.

Description

technical field [0001] The present invention relates to a redirection technology in a wireless communication system, in particular to a redirection method and device based on policy and charging control. Background technique [0002] With the development of wireless communication systems, in the standard system of the third generation partnership project phase 7 (3GPP Release7, 3rd Generation Partnership Project Release7), the policy and charging functions are controlled by the policy and charging control (PCC, Policy and Charging Control ) structure to achieve. The PCC architecture is a functional framework that can be applied to multiple access technologies. For example, the PCC architecture can be applied to the Terrestrial Radio Access Network (UTRAN, UMTS Terrestrial Radio Access Network) of the Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) , Global System for Mobile Communication (GSM, Global system for Mobile Communicat...
