Embodiment Construction

[0060] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0061] When the base station receives the paging message from the terminal in idle mode, it initiates paging within the coverage area of ​​the base station and forwards the paging message to the lower-level relay station; after receiving the paging message, the lower-level relay station initiates paging within the coverage area of ​​the relay station Paging, and forward the paging message to the next-level relay station. By sending it level by level and paging each level, it is paged within the coverage area of ​​the base station and the relay station, ensuring that the terminal can successfully receive the network side in any range. paging message.

[0062] The first embodiment of the present invention will be described below. This embodiment relates to a paging ...

Abstract

The invention relates to the field of wireless communication, and discloses a paging method and a wireless network which are used for normally paging a terminal in the event that a relay station (RS) is set in the network. The method comprises: a base station (BS) or the RS carries out paging within the range of the BS or the RS and issues a paging message step by step after receiving the paging message from the terminal under an idle mode; the BS or the RS can directly issue the paging message to a lower-level RS after receiving the paging message from the terminal under the idle mode; the BS or the RS can also initiate paging within the coverage range of the BS or the RS, and then issues the paging message to the lower-level RS if a response message from the terminal is not received within a preset time limit; when the RS or the BS receives a location update or network reentry request from the lower-level RS or the terminal or the maximum paging count is reached, the RS or the BS stops issuing the paging message; and the RS can also stop issuing the paging message after receiving a paging stop message from a high-level RS or the BS.

Description

[0001] The present invention is a divisional case of a Chinese patent application submitted to the China Patent Office on December 18, 2006 with the application number 200610169148.3 and the title of the invention "paging method and wireless network". technical field [0002] The invention relates to the field of wireless communication, in particular to the control technology of an idle mode terminal. Background technique [0003] 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 wav...
