Embodiment Construction

[0022] figure 1 It is a system structure diagram of a multi-frequency wireless network in an embodiment of the present invention. The system of the multi-frequency wireless network includes a mobile station (Mobile Station, MS), a microcell base station (microcell BaseStation, mBS), a macrocell base station (Macrocell Base Station) and a channel allocation center (Channel Allocation Center). Mobile stations 100, 101, 102, 103, 104, and 105 establish connections using wireless channels provided by base stations. The micro cell base stations 110, 111, 112, 113 or the macro cell base stations 120, 121 all provide a limited number of wireless channels. The channel assignment center 130 is connected to the external network 140, and assigns wireless channels of the micro cell base stations 110, 111, 112, 113 or macro cell base stations 120, 121 to the mobile station for connection establishment or handover. The following points are worth noting: 1. The channel distribution center ...

Abstract

A channel distribution system of multifrequency radio network includes channel distribution centre, micro-subarea base station, macro-subarea base station and mobile station. The method for channel distribution incldues the following: the channel distribution centre distributing radio channel of base station in micro-subarea or macro-subarea to the mobile station to be used by applying the method of recombination to requirement, when the mobile station is trying to set up connection or to carry on switching. A method of recombination to requiring works as distributing idle channel in micro-subarea first and secondly distributing idle channel in macro-subarea if there is no micro-subsarea channel; carrying on recombination, if there is no macro-subarea channel. Recombination is to switch connection of another station from macro-subarea to another micro-subarea to recover occupied macrosubarea channel and to distribute it to the

Description

technical field [0001] The present invention relates to a channel allocation (Channel Allocaiton) system and method for a multi-frequency wireless network (Multi-frequency Wireless Network), especially a system and method for repacking on demand (Repacking on Denmark, RoD) for Improve the call blocking rate (Call Blocking Probability) and call handover rate (Call Handover Rate) of the mobile station. Background technique [0002] A multi-frequency wireless network is characterized by including multiple base stations (BaseStation) operating in different frequency bands and mobile stations (Multi-frequency MobileStation) operating in multiple different frequency bands. Various base stations have cells (Cells) of various sizes to support mobile station reception. (In a wireless network, a cell refers to the signal coverage of each base station, that is, the receiving range of a mobile station.) Common multi-frequency wireless networks such as GSM 900 / 180...
