Problems solved by technology

[0009] It can be seen that the construction cost of strong base stations is much higher than that of ordinary base stations, so strong base stations cannot be widely deployed, and can only solve the problem of emergency communication in some key areas.

Embodiment Construction

[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0026] like figure 1 As shown, it is a flowchart of a disaster recovery method for a wireless access network according to an embodiment of the present invention, including the following steps:

[0027] In step S101, the common base station judges whether there is a transmission interruption caused by a disaster.

[0028] Step S102, if the ordinary base station judges that there is a transmission interruption caused by the disaster, the ordinary base station enters the wireless repeater working mode according to the preset wireless repea...

Abstract

The invention discloses a disaster tolerance method for a radio access network. The method comprises that: an ordinary base station judges whether transmission interruption condition caused by a disaster occurs or not; and if the transmission interruption condition caused by the disaster is judged to occur, the ordinary base station enters a radio repeater operating mode according to a preset radio repeater parameter, establishes connection with a nearby robust base station, and receives and forwards signals between the robust base station and a terminal. By the embodiment of the invention, the ordinary base station can automatically enter the radio repeater operating mode according to the preset radio repeater parameter after suffering from the disaster, establish the connection with the nearby robust base station, and receive and forward the signals between the robust base station and the terminal, thereby avoiding the large-scale establishment of the robust base stations and saving investment, particularly transmission link investment in satellite communication.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a disaster recovery method and a base station of a wireless access network. Background technique [0002] The wireless access network is mainly composed of base stations and base station controllers under the 2G or 3G architecture. The base station controllers are generally located in the core computer room, while the base stations are distributed in multiple locations. When a disaster occurs, the base station controller can recover quickly because it is in the environment of the core computer room and can perform disaster recovery backup due to the small number of equipment. However, because a large number of base stations adopt ordinary civil buildings, the building strength, power supply guarantee, and transmission guarantee are far inferior to the core computer room. Therefore, the base station and transmission (between the base station and the base station controller)...
