Method, device and system for accessing user terminal of fixed service area into network

Abstract

The embodiment of the invention discloses a method for accessing a user terminal of a fixed service area into a network, comprising the steps: receiving a descending channel message of a base station; obtaining a base station label or a belonging service area label of the base station; judging whether the obtained base station label or the belonging service area label of the base station is matched with a configured sign area label of the terminal; and if yes, executing a networking process. The embodiment of the invention also discloses a device and a system for accessing a user terminal of a fixed service area into a network, the user terminal of the fixed service area can be correctly accessed into the base station of the sign area so as to avoid a meaningless network accessing process, save networking time, and avoid the waste of terminal energy and network sources.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method, device and system for accessing a network by a user terminal in a fixed service area. 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 M...

Problems solved by technology

[0008] The inventors found that in the prior art, the particularity of users in the fixed service area is not considered in the process of terminal access to the network, and the user terminal in the fixed service area cannot determine whether the base station being connected belongs to the contracted area, which may cause fixed service Regional user terminals repeatedly connect to base stations that are not in the contracted area, and perform unnecessary network entry processes, which delays the time for successful network access, resulting in a waste of network resources and terminal energy
