Embodiment Construction

[0062] The present invention will be described in detail below in conjunction with the accompanying drawings and specific schemes.

[0063] The wireless communication system applied to the intelligent construction of the wireless relay in this scheme is as follows: figure 1 As shown, it includes the following parts:

[0064] 1) At least one base station, the base station sends synchronization signals and control information for access and control of the terminal and the relay station; the base station can communicate directly with the terminal; the base station can also communicate with the terminal through the relay station.

[0065] 2) At least one first-hop relay station (RS), which is directly connected to a base station, and the base station and wireless relay station send synchronization signals and control information for access and control of terminals and other relay stations.

[0066] 3) At least one terminal that communicates with the base station through the relay...

Abstract

The invention relates to a method for updating the connection relation of a wireless relay station. A management node in a wireless transmission network group keeps topology relation information of the group. The method of the invention comprises the steps that: (a) one wireless relay station RS1 is connected with a wireless transmission network group comprising a base station and a wireless relay station subordinated to the base station, and if the connection relation of the RS1 needs to be changed after judgment, a targeted node is selected; (b) the RS1 is instructed to update the connection to the targeted node; after receiving the instruction, the RS1 starts the connection updating and establishes a wireless link with a new node and also releases resources unused in a given data tunnel; (c) before or after the RS1 updates the connection relation, the management node which belongs to the transmission group updates the preserved wireless network topology information of the transmission group and then finishes the updating. The updating method of the invention can realize the updating of the connection relation of the wireless relay station and can further adopt measures to guarantee that the service interrupt time for holding terminals and that of RS are shortest.

Description

technical field [0001] The invention relates to a wireless transmission network, in particular to a method for updating connection relations of wireless relay stations in the wireless transmission network including base stations and wireless relay stations. Background technique [0002] Currently there are various wireless communication systems, and they have one thing in common: the site setup is complicated, the base station needs wired support, and the coverage of the base station is relatively fixed. Due to the complexity of the wireless communication environment, such as the obstruction of buildings on the propagation path, or obstacles between the base station and the user's receiving antenna and transmitting antenna, the user is in the blind area served by the base station. In this way, although the user is in the cell covered by the base station, it cannot maintain normal communication with the base station, resulting in a serious decline in the communication quality...
