Abstract

The embodiment of the invention discloses a method for accessing a terminal of a fixed or nomadic user to a network. The method is characterized by comprising the following steps: transmitting an access request message to an authentication, authorization and accounting server AAA; receiving an access granted message from the AAA, wherein the access granted message carries area information which is granted to access the terminal; converting the area information into a base station identification BS ID list which is granted to access the base station; and transmitting an authentication succeeded message to the terminal if the BS ID of the terminal accessed to the base station currently is in a range of the BS ID list so as to ensure that the terminal can carry out a subsequent network accessing process. The method and a device for accessing the terminal of the fixed or nomadic user to the network ensure that the terminal of the fixed or nomadic user can be correctly accessed in an area which is granted to access so as to restrict the area range of the terminal of the fixed or nomadic user accessing to the network.

Description

technical field

[0001] The invention belongs to the technical field of communication, and in particular relates to a method and a device for accessing a network by a fixed or nomadic user terminal. Background technique

[0002] WiMAX (Worldwide Interoperability for Microwave Access) is a wireless metropolitan area network technology based on the IEEE802.16 standard. The wireless side of the WiMAX network is a wireless metropolitan area network access technology based on the IEEE802.16d / e standard, using the physical layer of OFDM (Orthogonal Frequency Division Multiplexing) and OFDMA (OFDM Access) technology, which can effectively resist multipath fading. In the case of optimal channel fading, the transmission rate can approach 75Mbps.

[0003] WiMAX network logical architecture such as figure 1 As shown, the entire WiMAX network is mainly composed of the following three parts:

[0004] (1) Terminal: including SS (Subscriber Station, subscriber station) or MS (Mobile Sta...
