Problems solved by technology

[0026] The inventor found in the course of the invention that there is no association between different PCEFs under the same IP CAN Session (IP connection access network session), for example: there is a simultaneous use of A-PCEF and C-PCEF for the same IP CAN Session scenario, and there is no relationship between A-PCEF and C-PCEF

Embodiment 1

[0113] Embodiment 1. When PCRF interacts with AAA / SPR / HSS to obtain user subscription information, it obtains the HA information allocated by AAA to the user (that is, AAA / SPR / HSS is used as the allocation entity of C-PCEF), and when PCRF needs to issue rules, When the associated entity is located in PDF, PCRF adds C-PCEF location or address related information to the message sent to PDF and instructs PDF to send to C-PCEF; when associated entity is located in PCRF, PCRF directly sends information to A-PCEF and C-PCEF distribution rules. see Figure 14 shown, including the following steps:

[0114] Step 1: A-PCEF transmits the PCC rule request through PDF, and initiates the PCC Rules configuration process to PCRF for the IP-CAN Session of the terminal; when PCRF receives the PCC rule request sent by A-PCEF through PDF, it establishes a connection with the A-PCEF session, and record that the A-PCEF serves the IP-CAN Session.

[0115] The configuration process may include: cr...

Embodiment 2

[0131] Embodiment 2. After the user authentication process is successful, the A-PCEF obtains the HA information allocated for the user from the AAA / SPR / HSS (that is, the AAA / SPR / HSS is used as the allocation entity of the C-PCEF), and carries it to the PDF or PCRF. When PDF is used as the associated entity, PDF saves and associates the relationship between A-PCEF and C-PCEF, and after obtaining the PCC Rule from PCRF, sends it to A-PCEF and C-PCEF; when the associated entity is located in PCRF, PCRF distributes rules directly to A-PCEF and C-PCEF, and there may be PDFs on the distribution path. see Figure 15 shown, including the following steps:

[0132] Step 1: A-PCEF initiates a rule configuration request to PCRF through the PDF, and carries the HA address and / or HA location obtained during the authentication process in the initiated rule configuration request message; if the associated entity is located in the PDF, the PDF saves the HA Information, maintain the associat...

Embodiment 3

[0146] Embodiment 3. Both the A-PCEF and the C-PCEF initiate registration to the PCRF / PDF. The associated entity associates the session from the associated entity to the A-PCEF with the session from the associated entity to the C-PCEF according to the user identifier and the user's IP address. see Figure 16 shown, including the following steps:

[0147] Step 1: C-PCEF triggers the PCC Rules configuration process related to the IP-CANSession according to the bearer requirements of the terminal IP-CAN Session; the configuration process may include: creation, modification and / or deletion of PCC Rules, or IP -CAN Session establishment, modification or release, etc.

[0148] Step 1': A-PCEF triggers the PCC Rules configuration process related to the IP-CANSession according to the bearer requirements of the terminal IP-CAN Session; the configuration process may include: creation, modification and / or deletion of PCC Rules, or Establishment, modification or release of IP-CAN Sessi...

Abstract

The invention discloses a method, a device and a system for associating policy and charging execution function entity to realize the establishment of an association relationship between different PCEFs under the same session. The method comprises the following steps that the association entity obtains the information of each policy and the charging execution function entity PCEF serving the same session; the association entity establishes the association relationship of different PCEFs serving the session. The association entity comprises an acquisition unit for obtaining the information of each PCEF serving the same session; a PCEF association unit for establishing the association relationship of different PCEFs serving the session. The system comprises an association entity for obtaining the information of each PCEF serving the same session and establishing the association relationship of each PCEF and each PCEF serving the same session.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for associating policy and charging execution function entities. Background technique [0002] 1. WiMAX (Worldwide Interoperability for Microwave Access), the Chinese full name is Worldwide Access Microwave Interoperability, is a wireless metropolitan area network technology. [0003] see figure 1 Shown is a WiMAX network structure diagram. The WiMAX network is mainly composed of three parts: mobile terminal (Mobile Station MS / SS); access service network (Access Service Network ASN), which includes base station (Base Station BS) and access service network gateway (ASN Gateway ASNGW); and Connectivity Service Network (CSN), including Policy Server (PF), Authentication, Authorization and Accounting Server (AAA Server), Application Functional Entity (AF) and other logical entities. Among them, the R1 interface is a wireless air interface, which is mai...
