System and handover mechanism in frequency multilple band environment and equipment therefor

摘要

A mechanism for supporting the decision on performing a communication connection changeover of a subscriber terminal in a wireless communication network, in particular in a multiple band WLAN, is proposed. The subscriber terminal is a to communicate with an access node on two or more frequency bands. AP related communication information are detected which comprises, besides information indicating a multiple band capability, a traffic load, a frequency band coverage and/or a frequency channel information. The communication information are broadcasted, for example, by means of the AP beacon frame, processed and used for a decision on a communication connection changeover of the subscriber terminal.
