US 8,538,428 B2 · Radio coverage mapping for telecommunications network

Abstract

An arrangement for determining radio coverage provided by a telecommunications system to a user of a mobile device is disclosed. In the case of a GSM or UMTS mobile device, if the device is in the idle mode (step A) and if a paging operation is not scheduled (step B), the mobile device records and stores on the mobile device a characteristic of the radio coverage provided when the mobile device is at each of a plurality of locations visited by the user of the mobile device (step C). The arrangement also enables retrieval of the recorded and stored characteristic so that radio coverage provided to the device for the user at the locations can be evaluated. If the telecommunications system includes a plurality of networks, the mobile device will record and store the characteristic for each of the plurality of networks. The arrangement then enables the radio coverage provided by the respective networks to be evaluated, and an informed choice as to the best network for that particular user can be made.

Dependent claims

A method of determining radio coverage provided by a telecommunications system and providing coverage information that is specific to a particular user of a particular mobile device, wherein the telecommunications system includes a plurality of networks;

the method including:
operating the particular mobile device to record and store on the particular mobile device a characteristic for the plurality of networks of the radio coverage provided when the particular mobile device is at each of a plurality of locations visited by the particular user of the particular mobile device, and enabling retrieval of the recorded characteristic to evaluate the radio coverage provided at the locations by the respective networks to the device for the particular user;
wherein the characteristic is signal strength and/or quality;
and
wherein the operating step is performed while the particular mobile device is in an idle or inactive communication mode, and wherein the operating step is interrupted when the particular mobile device is required to operate in an active communication mode;
whereby the particular user can determine which of the plurality of networks provides the best coverage for his or her particular needs, and is provided with a personalized assessment of the coverage quality provided by different network operators based on locations that the particular user visits.
