Embodiment Construction

[0057] The present invention will be described in detail below in conjunction with the accompanying drawings for the best implementation of the present invention. First of all, it should be pointed out that the meanings of the terms, words and claims used in the present invention should not be limited to their literal and ordinary meanings, but also include meanings and concepts that are consistent with the technology of the present invention. This is because As the inventor, definitions of terms should be given appropriately so as to best describe the present invention. Therefore, the configurations given in this specification and the accompanying drawings are only preferred implementations of the present invention, rather than enumerating all technical characteristics of the present invention. In addition, there are various equivalents or modifications that can replace the solutions of the present invention.

Abstract

The method includes following steps: (1) user's up layer registers a power supply event on switching layer not relevant to media, the power supply event includes a power supply threshold of equipment; (2) when capacity of power supply of equipment at bottom layer is lower than threshold value of power supply of equipment, the switching layer not relevant to media triggers the event of power supply event to user's up layer; (3) based on information carried in power supply event, user's up layer decides to carry out switching. Through triggered event to carry information at bottom layer, user's up layer can decide switching strategy based on the said carried information. In addition, the invention adds information of power expenditure for different network structures in order to make more correct and effective decision in decision for switching among isomeric networks.

Description

technical field [0001] The invention relates to the field of power management of communication networks, in particular to a power management method and a power information query method in heterogeneous network switching. Background technique [0002] There are many networks with different architectures in the existing communication system, such as 802.11, 802.16, 3GPP (3rd Generation Partnership Project, third-generation mobile communication standardization partner project) and other networks. However, it is difficult to guarantee service in the above heterogeneous network Convenient switching and roaming under continuous conditions. [0003] It is based on the above reasons that the IEEE 802.21 (Media-Independent Handover) protocol was created. This protocol is a standard for optimizing handover in heterogeneous networks by providing link layer information and other relevant network information to the upper layer. It is used to meet the requirements of software and hardwa...
