AI Technical Summary

Problems solved by technology

[0025] There are great differences between WiMAX network and WLAN network in terms of network architecture, security guarantee, QoS mechanism, etc. If the I-WLAN system is completely copied, many features of the WiMAX network system will not be able to be applied, and at the same time it will bring many problems
For example: 3GPP and WiMAX networks cannot be combined in terms of QoS delivery and guarantee. The IPSec tunnel between PDG and terminals makes it impossible for the WiMAX network to classify the passing data packets, and cannot use the QoS (Quality of Service) of the WiMAX network. Mechanism, only the DiffServ mechanism on the IP network can be used; the billing granularity is relatively coarse, and it can only be billed based on user or IP Session (IP session) granularity, and billing based on flow cannot be realized; Encapsulation makes the protocol header very expensive; the IPsec tunnel between MS and PDG makes it impossible to use the MS's IDLE (idle) mechanism; does not support mobility between WiMAX and 3GPP networks

Embodiment Construction

[0041] Embodiments of the present invention provide a method and system for integrating a WiMAX network and a 3GPP network based on an I-WLAN architecture. The embodiment of the present invention proposes a new WiMAX network and 3GPP network fusion method and system based on the I-WLAN architecture, does not change the existing WiMAX and 3GPP network architecture, and has less functional requirements for WiMAX and 3GPP network entities, Does not affect existing WiMAX and I-WLAN network protocols. Utilize the security guarantee mechanism of the WiMAX system itself to realize the security of data transmission in the access network and air interface under the converged system; use the QoS guarantee mechanism of WiMAX and the classification and control function of business flow to improve the utilization efficiency of network resources and the accuracy of billing; WiMAX network and 3GPP network are better integrated in aspects such as QoS guarantee, billing, handover between syste...

Abstract

The embodiment of the invention discloses a method for integrating a WiMAX network and a 3GPP network, which comprises: establishing a tunnel between a home agent HA or an access service network gateway ASN-GW of the WiMAX network and the 3GPP network; and using the tunnel for data transmission of user terminals which access the 3GPP network through the WiMAX network. The embodiment of the invention also discloses a system for integrating the WiMAX network and the 3GPP network. The method and the system do not change the prior WiMAX network architecture and the prior 3GPP network architecture, have small functional requirements on a WiMAX network entity and a 3GPP network entity, do not influence the prior WiMAX and I-WLAN network protocol, and simultaneously utilize a complete security mechanism of the WiMAX network to guarantee security of data passing through the WiMAX network.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method and system for integrating a WiMAX network and a 3GPP network based on an I-WLAN architecture. Background technique [0002] WiMAX (Worldwide Interoperability for Microwave Access) is a wireless metropolitan area network technology based on the IEEE802.16 standard. The WiMAX network is mainly composed of three parts: the client, the access service network (including the base station and the access service network gateway) and the connection service network (including logical entities such as prepaid servers and authentication, authorization and billing servers). The wireless side of the WiMAX network is a wireless metropolitan area network access technology based on the IEEE802.16d / e standard. What is mainly followed now is the IEEE802.16-2004 (802.16d) standard formulated in July 2004. IEEE802.16-2004 (802.16d) standard operating frequency band is 2GHz to 11GHz, whic...
