Abstract

A method for policy and charging control includes: when a terminal accesses a Code Division Multiple Access (CDMA) system in mobile Internet Protocol (IP) mode, the anchor gateway and the Packet Data Serving Node (PDSN) both establish IP-Connectivity Access Network (IP-CAN) sessions with the Policy and Charging Rules Function (PCRF) entity; the PCRF entity relates the two IP-CAN sessions established with each other; and the PCRF entity distributes the charging policies to the charging network element which is either the PDSN or the anchor gateway. A policy and charging control system and a PCRF entity are also provided in the present invention. In the present invention, the existing policy and charging control (PCC) solution is improved and used in CDMA2000 systems, and the changes to the existing CDMA2000 system architecture are small and easy to implement.

Description

technical field

[0001] The invention relates to the communication field, in particular to a system and method for implementing policy and charging control in a CDMA (Code Division Multiple Access, Code Division Multiple Access) system. Background technique

[0002] The CDMA2000 1x and HRPD (High Rate Packet Data, High Rate Packet Data) network architecture defined by the 3rd Generation Partnership Project 2 (3GPP2, 3rd Generation Partnership Project 2) is mainly composed of MS / AT (Mobile Station / Access Terminal, mobile terminal / Access terminal equipment), RAN (Radio Access Network, wireless access network), PDSN (Packet DataServing Node, packet data service node), HA / LMA (Home Agent / Local MobilityAnchor, Home Agent / Local Mobility Anchor), AAA (Authentication, Authorization, Accounting, authentication authorization accounting) server and other core network equipment and supporting nodes. Such as figure 1 As shown, a partial network reference model of 1x and HRPD PDS (Packe...

Examples

Embodiment 1

[0075] This example requires a reference architecture image 3 and process Figure 6 ; When the user starts up, the MS / AT initiates CMIPv4 access to the CDMA20001x or HRPD network, and the MS / AT initiates the access procedure to the CDMA2000 system by sending a mobile IP registration request to the PDSN. After PDSN receives the mobile IP registration request, PDSN, as PCEF-2, establishes IP-CAN session-2 with PCRF, and informs PCRF of the access mode of MS / AT (CMIPv4-support reverse tunnel); HA / LMA in After receiving the mobile IP registration request sent by PDSN, HA / LMA acts as PCEF-1 and establishes IP-CAN session-1 with PCRF, because when establishing two IP-CAN sessions, user identification, packet data network identification, The information such as the terminal IP address is the same, and the PCRF will associate the two IP-CAN sessions; and, PCEF-2 informs the PCRF that the current terminal access mode is: CMIPv4-supports reverse tunneling, so PCRF knows that at this t...

Embodiment 2

[0093] This example requires a reference architecture Figure 4 and process Figure 7 ; When the user starts up, the MS / AT initiates CMIPv4 access to the CDMA20001x or HRPD network, and the MS / AT initiates the access procedure to the CDMA2000 system by sending a mobile IP registration request to the PDSN. After PDSN receives the mobile IP registration request, PDSN, as PCEF-2, establishes IP-CAN session-2 with PCRF, and informs PCRF of the access mode of MS / AT (CMIPv4-does not support reverse tunnel); HA / LMA After receiving the mobile IP registration request sent by the PDSN, HA / LMA acts as PCEF-1 and establishes IP-CAN session-1 with PCRF, because when establishing two IP-CAN sessions, the user ID and packet data network ID and the terminal IP address and other information are the same, PCRF will associate the two IP-CAN sessions; and, PCEF-2 informs PCRF that the current terminal access method is: CMIPv4-does not support reverse tunneling, so PCRF knows this When charging,...

Embodiment 3

[0111] This example requires a reference architecture image 3 and process Figure 8 ; When the user starts up, the MS / AT initiates PMIPv4 access to the CDMA2000 1x or HRPD network, and the MS / AT initiates the access procedure to the CDMA2000 system by sending a PPP session to the PDSN. After the PDSN receives the IP control protocol negotiation request of the PPP session, the PDSN, as PCEF-2, establishes an IP-CAN session-2 with the PCRF, and informs the PCRF of the access mode (PMIPv4) of the MS / AT; After receiving the proxy mobile IP registration request sent by PDSN, HA / LMA acts as PCEF-1 and establishes IP-CAN session-1 with PCRF, because when two IP-CAN sessions are established, user identification and other information (APN, etc.) It is the same, PCRF will associate the two IP-CAN sessions; and, PCEF-2 informs PCRF that the current terminal access mode is: PMIPv4, so PCRF knows that the functional network element for charging at this time is HA / LMA, When PCRF delivers...
