Measurement data record method for detecting hybrid mobile tune away

Abstract

An apparatus in one example has: a first communication network optimized for high-speed packet data services; a first database operatively coupled to the first communication network; a second communication network for providing both voice and slow data-rate data services; a second database operatively coupled to the second communication network; and an operations platform operatively coupled to the first and second databases. The first communication network optimized for high speed packet data will generate in the first database a record which will have at least: mobile ID type, mobile ID, connection ending time, cell, sector, carrier information; and last signal strength value. The second communication network providing both voice and low speed packet data will generate, in the second data base, a record that will have at least mobile ID type, call start time, call length, mobile ID (ESN/MEID), call type (data or voice), cell, sector, carrier information; and call disposition. The operations platform will link the records on the two databases based on mobile ID, call ending time, and the call start time. The linking of the two records with matching mobile ID and time stamps will give information about mobile tuneaway and the reason for the tune away.
