Abstract

An embodiment of the invention provides a signal intensity-based mobile network multi-link bandwidth distribution method and device. Operator base stations connected with all the links at the present moment in an aggregated link, theoretical bandwidths of all the links, and base station signal intensity information received via a mobile device are obtained; according to the obtained base station signal intensity information received via the mobile device, bandwidth floating ratios of all the links in a next time interval can be calculated; according to the bandwidth floating ratios of all the links, predicted bandwidth values of the links in the next time interval can be obtained via the theoretical bandwidths; according to the predicted bandwidth values of the links, bandwidth distribution for data transmission between the mobile device and the base stations in the next time interval is performed. Thus load balancing of link aggregation in a mobile Internet is realized, and good link aggregation effects are exerted in the mobile Internet.

Description

technical field [0001] The embodiments of the present invention relate to the field of link aggregation, and in particular to a method and device for multi-link bandwidth allocation of a mobile network based on signal strength. Background technique [0002] Link aggregation technology refers to bundling multiple physical ports together to form a logical port, so as to realize the load sharing of outgoing / incoming traffic among member ports. When the switch detects that a link failure occurs on one of the member ports, it stops sending packets on this port, and recalculates the port to send packets on the remaining links according to the load sharing policy, and restarts again after the faulty port recovers. Calculate the packet sending port. Link aggregation is a very important technology in terms of increasing link bandwidth and realizing link transmission elasticity and redundancy. [0003] Existing link aggregation schemes are mostly used in wired data switching network...
