Claim Text:
1. A method for coordinating an evolved multimedia broadcast/multicast services (eMBMS) group call, comprising: receiving, at an application server, a selected geographic area from a call originator, wherein the selected geographic area is defined through one or more inputs to a user interface associated with a user equipment; establishing an eMBMS bearer to support ad hoc group calling in the selected geographic area received from the call originator based on a discovered mapping among eMBMS network components that service the selected geographic area; pre-provisioning the call originator with a pool of network group identifiers that uniquely identify a multimedia broadcast/multicast service (MBMS) to facilitate establishing an ad hoc group call in the selected geographic area over the established eMBMS bearer; and broadcasting, to one or more group members present in the selected geographic area, a message to facilitate detecting the ad hoc group call, wherein the broadcasted message includes the pool of network group identifiers.
