Mobile assisted channel allocation
First Claim
1. A signalling method in a radiocommunication system for reporting measurements associated with downlink channels available to a base station in which the measurements can be used to allocate channels for new calls in a cell serviced by the base station by using a plurality of idle mobile stations within the cell as measurement probes to procure the measurements comprising the steps of:
- broadcasting a single message from a base station on a control channel to a plurality of idle mobile stations instructing each of said idle mobile stations to perform said measurements; and
including, as part of said message, a list of frequencies on which each of said plurality of idle mobile stations are to perform said measurements.

Abstract
The present invention relates to systems and methods for allocating channels in a radiotelephone system wherein local estimation of interference for a potential new connection is achieved by measuring interference on the available downlink channels at a plurality of locations within a cell. The measurements can be made, for example, by already connected mobile stations, mobile stations which are not connected, fixed measurement stations or any combination thereof.

4. A measurement method in a radiocommunication system comprising the steps of:
-
broadcasting a single message on a control channel instructing a plurality of idle mobile stations to measure on at least one frequency; receiving the message at the idle mobile stations; measuring, at said plurality of idle mobile stations, on said at least one frequency; and reporting, to said radiocommunication system, each of the results of said idle mobile stations'"'"' measurements. - View Dependent Claims (5, 6, 7, 8, 9, 10)

17. A signalling method between a mobile station and a fixed part of a radiocommunication system comprising the steps of:
-
performing, by said mobile station, one of a plurality of types of measurements; transmitting, in a report from said mobile station to said fixed part of said radiocommunication system, an indication of said type of measurement performed by said mobile station; transmitting, in said report from said mobile station to said fixed part of said radiocommunication system, an indication as to whether said measurement is based upon a full measurement interval; and transmitting to said radiocommunication system said measurement.

21. A signalling method in a radiocommunication system for reporting measurements associated with downlink channels available to a base station in which the measurements can be used to allocate channels for new calls in a cell serviced by the base station by using a plurality of idle mobile stations within the cell as measurement probes to procure the measurements comprising the steps of:
-
receiving a message from a fixed part of said radiocommunication system in an idle mobile station; performing a measurement by the idle mobile responsive to said message; and transmitting a measurement value from the mobile station at a time corresponding to a type of access specified in the message. - View Dependent Claims (22, 23)

24. A measurement method in a radiocommunication system comprising the steps of:
-
receiving a message on a broadcast control channel instructing a mobile station to measure a serving digital control channel to which said mobile station is locked; measuring a characteristic of said serving digital control channel plurality of times; reporting said measured characteristic to said radiocommunication system; averaging said measured characteristic; reporting said averaged measured characteristic to said system; determining if said plurality of times is equal to a full measurement interval; and providing an indication to said system of whether said averaged measured characteristic was taken over said full measurement interval.
