11. A system that implements a Multicast-Broadcast Multimedia Service (MBMS) area manager tool implemented for programmatically creating Multicast-Broadcast Single Frequency Network (MBSFN) areas, the MBMS area manager tool adapted to:
create a plurality of MBSFN area patterns, wherein for each MBSFN area pattern of the plurality of MBSFN area patterns:
the MBSFN area pattern comprises one or more subframe configurations for MBMS resource allocation; and
each subframe configuration of the MBSFN area pattern defines a set of subframes for MBMS resource allocation for the MBSFN area pattern; and
create a plurality of MBSFN areas that cover a desired geographical area using a select one or more of the plurality of MBSFN area patterns,
wherein the plurality of MBSFN areas is a plurality of hexagon-shaped MBSFN areas, and creating the plurality of MBSFN areas comprises creation of the plurality of hexagon-shaped MBSFN areas that cover the desired geographical area using three or more select MBSFN area patterns from among the plurality of MBSFN area patterns, and
wherein creation of the plurality of hexagon-shaped MBSFN areas comprises:
obtain input from an operator that defines the desired geographical area;
obtain input from the operator that defines one or more parameters related to creation of the plurality of hexagon-shaped MBSFN areas, the one or more parameters comprising information that indicates a desired MBSFN area pattern type;
select the three or more selected MBSFN area patterns from a plurality of MBSFN area patterns predefined for the desired MBSFN area pattern type; and
generate plurality of hexagon-shaped MBSFN areas using the three or more selected MBSFN area patterns.
