Embodiment 1

[0033] The inventors of the present application aim at controlling the interference between mobile station cells under the mobile coverage application scenario of the existing satellite link and cellular wireless network networking, and propose that the GPS position information can be reported through the access network nodes, and the GPS position information can be reported through each access network node GPS position information, calculate the distance between each node, and control the transmission power of each node through the distance information, that is, the interference between cells when the signals of multiple nodes overlap can be controlled. Based on the above ideas, this embodiment provides a mobile The coverage interference control method mainly includes the following steps:

[0034] The network side receives the GPS location information reported by each access network node, and calculates the distance between each access network node according to the GPS locatio...

Embodiment 2

[0057] This embodiment provides a mobile coverage interference control device, which mainly includes the following units:

[0058] The first unit receives the GPS location information reported by each access network node, and calculates the distance between each access network node according to the GPS location information reported by each access network node;

[0059] The second unit, when the distance between any two access network nodes is less than or equal to the first set threshold (also called the minimum distance threshold), download to any one or both of the two access network nodes Sending a transmission power adjustment command, the transmission power adjustment command is used to instruct the access network node to reduce the transmission power.

[0060] Specifically, the transmit power adjustment command issued by the network side may carry power adjustment value information.

[0061] In some preferred solutions, when the distance between any two access network n...

Abstract

Disclosed are a mobile coverage interface control apparatus and method. The method comprises: a network side receives global positioning system (GPS) position information reported by access network nodes, and calculates, according to the GPS position information reported by each access network node, a distance between every two access network nodes; and the network side issues, if the distance between every two access network nodes is smaller than or equal to a first set threshold, a transmitting power adjustment command to one or both of the two access network nodes, the transmitting power adjustment command being used for instructing the access network nodes to turn down transmitting power.

Description

technical field [0001] The present invention relates to the technical fields of satellite communication and wireless mobile communication, and in particular to an application scenario in which a satellite communication link and a cellular communication technology are combined to form a network. Background technique [0002] At present, the wireless cellular communication system can generally use satellite links for some application scenarios such as oceans or plateaus that are not conducive to wired links. Especially for marine application coverage, satellite links and wireless cellular system mobile station coverage can be used. The networking method saves operating costs and can flexibly adapt to the communication needs of mobile groups. Because the coverage of the mobile station moves with the movement of the mobile object (such as a ship, a car, etc.) where the station is located, its signal coverage geographical location is also constantly changing. When multiple mobile...
