Problems solved by technology

[0008] For some operators in some countries, due to license restrictions, they can only operate fixed or nomadic network services. Therefore, for fixed and nomadic users, it is required to restrict the mobility of their terminals
[0009] The inventor found that in the prior art, there are no relevant parameters in the terminal access process to limit the mobility of the terminal, so it is impossible to realize that the terminal of a fixed or nomadic user can access the network in an area where access is allowed, and after the terminal accesses the network, Unable to limit the mobile range of the terminal

Embodiment 1

[0049] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The following embodiments will be described by taking the Wimax network as an example. Refer to figure 2 , a method for accessing a network by a fixed or nomadic user terminal in an embodiment of the present invention includes:

[0050] 201. The terminal MS initiates an initial network access and authentication process;

[0051] During this process, the terminal interacts with the base station and the Authenticator, and the Authenticator can obtain the BS ID of the terminal currently accessing the base station and the identification information of the terminal. This step belongs to the prior art and will not be described in detail;

[0052] 202. The Authenticator sends an Access-Request message to the AAA server;

[0053] In this step, the identification information of the terminal is carried in the request message, which belongs to the prior art and...

Embodiment 1

[0104] For the first embodiment, the embodiment of the present invention also discloses a device, which can be an authenticator, refer to Figure 5 ,include:

[0105] The first sending module: used to send an access request message to the accounting, authentication and authentication server AAA;

[0106] A receiving module: used to receive an access permission message from the AAA, and convert the regional information in the AAA access permission message into a list of base station identification BS IDs that the terminal is allowed to access the base station;

[0107] Save module: used to save the BS ID list that the terminal is allowed to access the base station;

[0108] Judging module: judging whether the BS ID of the base station currently accessed by the terminal is within the range of the BS ID list, and if so, notifying the second sending module;

[0109] The second sending module: used to send an authentication success message to the terminal.

[0110] The above dev...

Embodiment 3

[0120] For the third embodiment, the embodiment of the present invention also discloses a device, which can be an authenticator, refer to Figure 7 ,include:

[0121] Mapping module: used to map the BS ID of the terminal currently accessing the base station to the location information of the terminal currently accessing the base station;

[0122] The first sending module: used to send an access request message to the AAA, where the access request message carries the location information of the terminal currently accessing the base station;

[0123] Receiving module: used to receive an access permission message or an access rejection message from the AAA;

[0124] The second sending module: used to send an authentication success message or an authentication failure message to the terminal.

[0125] For the third embodiment, the embodiment of the present invention also discloses an AAA server, refer to Figure 8 ,include:

[0126] A receiving module: used to receive an acces...

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...
