초록 ▼

In a mobile cellular communication system, adjacent basestations BS1-BS4 are assigned different selections of different frequency channels to communicate with mobiles in their cells (10, etc.). To improve system quality and capacity, a basestation selects a frequency channel which is not assigned to it or any neighbour station, and makes test communications on that frequency channel with mobiles (e.g. MS1) in its cell. The basestation assesses the potential performance of that frequency channel, and neighbour basestations can monitor for potential interference on that frequency channel. The information so gathered can be analysed by an operations maintenance station OMC.

대표청구항 ▼

[ What is claimed is:] [1.] In a mobile telephone system comprising a plurality of basestations each of which has a respective plurality of frequency channels assigned to it, the assignments being such as to minimize or obviate the sharing of potentially interfering frequency channels between neighbour basestations, a method of testing the utility of potential frequency channels for a basestation, wherein a test channel is selected with a frequency which is disjoint with the frequency channels assigned to that basestation and neighbour basestations, and that basestation sends test messages on the test channel to mobiles in or near its cell and records for analysis the results returned from the mobiles;wherein the test messages are sent to active mobiles;wherein the frequency channels are divided into time slots and mobiles monitor a plurality of frequency channels and send to the basestation a frequency channel quality list of the strongest frequency channels, the basestation determining whether the test channel is included within the list received form the mobile;wherein the frequency channels monitored by a mobile are determined by a frequency channel list held within the mobile, where the basestation commands the test channel to be temporarily included in that list;wherein the basestation selects mobiles in dependence on the inclusion within their frequency channel quality lists of frequency channels assigned to particular neighbour basestaitons.
