Abstract

The present invention discloses a microwave access global interoperability access network system, the system at least includes BS, BSSN and DGW, wherein, BS includes a MAC / PHY module, and the MAC / PHY module is used for user terminals to be accessed Send the authentication information to the BSSN, and after receiving the authentication result returned by the BSSN, and when there is a service connection to be established, send a service request to the BSSN, and send it to the DGW according to the service tunnel information returned by the BSSN User plane data; BSSN, including an SGW module, the SGW module is used to interact with the core network according to the received authentication information, perform authentication on the user terminal, and send the authentication result to the BS, and according to The received service request establishes a service tunnel between the BS and the DGW, and returns service tunnel information to the BS; the DGW is used to send the user plane data sent by the BS to the Internet. Therefore, a cellular networking based on the IEEE 802.16 protocol is provided, and the networking has high robustness.

Description

technical field

[0001] The invention relates to wireless broadband access technology, in particular to a worldwide interoperability for microwave access (WiMAX) access network system. Background technique

[0002] The IEEE 802.16 protocol defines the fixed broadband wireless access (BWA) wireless metropolitan area network standard, which defines different physical layer technologies for different frequency bands. The scope of application of this standard is mainly for residential, small office / home office (SOHO), teleworkers and small business users (SME) markets.

[0003] In December 2001, the Institute of Electrical and Electronics Engineers (IEEE) promulgated the IEEE 802.16 standard for providing the last mile wireless broadband access in the metropolitan area network, and its operating frequency band is between 10G and 66GHz. But the current 802.16 standard mainly includes three standards: 802.16a, 802.16RevD and 802.16e. Among them, 802.16a is designed for non-line-o...
