Abstract
The disclosure generally relates to techniques that may be used to coordinate an evolved multimedia broadcast/multicast services (eMBMS) geo-location based group call. More particularly, an eMBMS bearer may be established to support a group call based on a mapping among eMBMS network components that service a geographic area selected by an originator associated with the group call (e.g., an area that the call originator defines according to latitude and longitude coordinates, a selected region on a map that displays available group members in the selected region, network identifications, etc.). The group call may then be initiated over the established eMBMS bearer using network group identifiers associated with the call originator and one or more group members present in the selected geographic area and unicast service with a dedicated link to group members located outside the selected geographic area may be established to include such group members in the group call.
