Evolved multimedia broadcast/multicast services (eMBMS) geo-location based group call

摘要

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.

主权项

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.
