Problems solved by technology

[0012] Although the above-mentioned WiMAX system has such superior performance, because the IEEE802.16 series protocol only stipulates the air interface part in the wireless network architecture of the WiNMAX system, it does not stipulate that the WiMAX access network (WiRAN) accesses such as the Global System for Mobile Communications (GSM), code division multiple access (CDMA) system and wideband code division multiple access (WCDMA) system and other core network network architecture and access methods, so the subscriber station (SS) and mobile station (MSS) of the WiMAX system cannot pass through WiRAN is connected to the core network, making it impossible to use the rich network resources and service functions in the core network

Abstract

A worldwide interoperability for microwave access network includes: a medium access control and physical layer module, a radio resource management module and a gateway module. A method for accessing the core network of the worldwide interoperability for microwave access network system includes the steps of: firstly, the terminal user station / mobile station transmits the service request; then the worldwide interoperability for microwave access network creates the private physical link and service link and creates the user side example for transmitting the service data according to the service request; the core network and the worldwide interoperability for microwave access network ensure that the connection has been created successfully by the interaction. The present invention could realize the purpose of the worldwide interoperability for microwave access network accessing the core network.

Description

technical field [0001] The invention relates to a wireless broadband access technology, in particular to a microwave access global interoperability (WiMAX) system access network, and a method for implementing access to a core network by using the access network. Background technique [0002] 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-of-sight (NLOS) broadband fixed access systems operating in the 2-11GHz frequency band, and was approved by IEEE in January 2003; 802.16RevD is an enhanced version of 802.16a, the main purpose of which is Support indoor customer premises equipment (CPE); 802.16e is a further extension of ...
