Abstract
When an Internet protocol connection for a given mobile communications unit already exists, that existing link can be used to conduct an Internet protocol communication with that mobile communications unit. When such a link does not already exist, and a need exists to convey information to the mobile communication unit via such a link, a message can be provided to the mobile communications unit via a non-Internet protocol wireless link to cause the mobile communications unit to self-initiate establishment of such an Internet protocol communications link. Upon establishing such a link, the requesting entity, service, or application can use that link to facilitate the desired Internet protocol-based communication.
