A method and apparatus for multi-media communication includes transmitting a first session invite request having a plurality of first call transaction identifiers, wherein each of the first call transaction identifiers has a first call transaction value. The method comprises the following steps: creating a database of Positional Reality Images that substantially accurately represents the real site, and accessing the database of Positional Reality Images that substantially accurately represents the real site in order to navigate a vehicle around said real site. Call flow embodiments that enable this management of group call service across urban area boundaries are described in detail. Subsequently, the B-type converter circuit generates fifth and sixth voltages with the common voltage segment between them. One improved dimensional control includes thickness. The substantially prevents undesired power-on sequence currents from flowing between the first and second IC terminals.
