Claim Text:
1. A method comprising: receiving, by a mobile device, a radio signal corresponding to a multicast broadcast of content; measuring, by the mobile device, a strength of the received radio signal; determining, by the mobile device, a minimum signal strength to receive the content associated with the multicast broadcast based on a particular modulation coding scheme (MCS) being used to broadcast the content, a particular symbol rate being used to broadcast the content, and an identification of a particular Multicast Service Single Frequency Network (MBSFN) coverage area associated with the received signal; determining, by the mobile device, a signal quality metric, associated with the multicast broadcast, the signal quality metric being based on a difference between the measured strength of the radio signal and the determined minimum signal strength; and wherein the determining of the minimum signal strength includes: determining, by the mobile device, a theoretical signal strength required to receive the content from an MBSFN of the particular MBSFN coverage area, based on the particular MCS and a particular symbol rate used to broadcast the content, determining, by the mobile device, an offset value based on the particular MCS, the particular symbol rate, and the particular MBSFN coverage area, of a plurality of MBSFN coverage areas, of the particular MBSFN, the plurality of MBSFN coverage areas corresponding to different offset values representing current transmission conditions of the plurality of MBSFN coverage areas; and providing, by the mobile device, a visual indication of the signal quality metric.
