Paging method and wireless network

Abstract

The invention relates to the wireless communication field and discloses a paging method and a wireless network. The invention can ensure that the normal paging of terminals can be carried out even when relay stations are arranged in the network. In the invention, when receiving paging information from a terminal with idle mode, a base station or a relay station can carry out paging in the scope itself and send the paging information down step by step. When receiving the paging information from the terminal with idle mode, the base station or the relay station can directly send the paging information to a subordinate relay station, or can carry out paging in the coverage area of the base station or the relay station; if the responding information from the terminal is not received in a preset time limit, the paging information is sent to the subordinate relay station. When the base station or the relay station receives the location updating or network reentrance request from the subordinate relay station or the terminal, or when paging frequency reaches the maximum, the sending of the paging information is stopped. When receiving the information of stopping paging from a superior relay station or the base station, the relay station stops sending paging information.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to the control technology of an idle mode terminal. Background technique [0002] With the increasing demand for broadband wireless communication, the demand for wireless bandwidth becomes larger and larger, so higher and higher carrier frequencies are used in new protocols and wireless communication systems, however, due to the Attenuation increases with frequency. Therefore, high carrier frequency must face the problem of high attenuation, and the use of high carrier frequency limits the coverage of the base station. In addition, in a wireless communication system, due to reasons such as path attenuation of electromagnetic waves or building occlusions, the strength of wireless communication signals in some areas is low, and the communication quality of mobile terminals located in these areas will become very poor. [0003] In order to increase the coverage of the base statio...
