Problems solved by technology

[0006] However, at present, 3G users cannot perform access authentication and authorization in NGN, that is, they cannot successfully attach
Also, due to the lack of corresponding mechanism between RACF and PCC, S9 cannot be established * session, impact policy control and management

Embodiment Construction

[0056] Generally speaking, when performing user attachment, NACF in NGN supports authentication and authorization mechanisms based on 3GPP, and there is interaction between NACF and 3GPP AAA server, so that 3GPP user identity transfer in NGN can be carried out. For example: 3G users are authenticated and authorized based on the 3GPP authentication and authorization mechanism during the NGN attachment process, and the IMSI (International Mobile Subscriber Identity) is reported to the 3GPPAAA server through the NACF. It should be noted that the 3GPP user identity can be expressed in various forms, such as IMSI, IMEI (International Mobile Equipment Identity) and so on. The following only takes the IMSI as an example for description.

[0057] NACF ​​assigns IP addresses to 3G users, and pushes the user access list to RACF; wherein, the user access list includes: IP address, and / or IMSI, and / or user QoS list, logical access identifier, and / or physical Access identifier, and / or acc...

Abstract

The invention discloses a method and a system for controlling a heterogeneous network. Both the method and the system can receive a user identity through a network attachment control function on the basis of a third-generation partner plan AAA server; the interactive authentication is executed by a user, the network attachment control function and the third-generation partner plan AAA server according to the user identity; and after approved authentication, the network attachment control function allocates an internet protocol (IP) address to the user. Due to the adoption of the method and the system, the third generation (3G) users can be successfully adhered into a next generation network (NGN); therefore, the subsequent treatment such as session establishment, strategy supply, session release and the like between a resource access control facility (RACF) and a policy control and charging (PCC), so the strategy control and the strategy management are not influenced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a heterogeneous network control method and system. Background technique [0002] With the development of network technology and user demands for services, multi-mode terminals need to implement attachment control and policy management of heterogeneous networks, so that multi-mode terminals can access other networks and carry out services. Since different network connections have different characteristics and transmission capabilities, they can better meet the needs of users with multiple services. [0003] Both NGN (Next Generation Network) and 3G networks have deployed and implemented their respective resource control systems and service functions. 3G users (such as: multi-mode mobile terminals) access and access services in the NGN network through the NGN network. The RACF (Resource Admission Control Function) entity in the NGN needs to interact with the PCRF (Policy and Cha...
