Embodiment Construction

[0069] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0070] In order to make the advantages of the technical solution of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0071] This embodiment provides a resource scheduling method, such as figure 1 As shown, the method includes:

[0072] 101. The source station acquires a non-interference global link identifier GLID set.

[0073] Wherein, the non-interference...

Abstract

An embodiment of the invention discloses a method and a device for dispatching resources. According to a source station and a destination station corresponding to a target global link, whether other interference-free global link sets of the target global link exist in a network or not is judged. If other global link sets exist, the source station can send a request to a central coordinator (CCo) for multiplexing interference-free bandwidth resources of the other global links, or after the interference-free global link sets of the target global link between the source station and the destination station are directly acquired through the CCo, the CCo dispatches the target global link between the source station and the destination station to multiplex the bandwidth resources of the global links in the interference-free global link sets, and accordingly, use ratio of the bandwidth resources in a broadband PLC (programmable logic controller) network is increased.

Description

technical field [0001] The present invention relates to the field of communication systems, in particular to a resource scheduling method and device. Background technique [0002] Power line communication is a special communication method that uses high-voltage power lines (35kV and above voltage levels), medium-voltage power lines (10-30kV voltage levels) or low-voltage power lines (380 / 220kV subscriber lines) as information transmission media for information transmission. This technology loads the high-frequency signal carrying information onto the power line, uses the power line for data transmission, and separates the high-frequency signal from the power line through a dedicated power line modulator / demodulator, and transmits it to the terminal equipment. [0003] From the perspective of power line communication application, with the development of network technology and multimedia technology, the trend of applying it to home broadband network and smart grid is becoming ...
