1. A method for optimizing call setup latency comprising:

  • updating client location information using at least one application server to provide a location update while at least one client moves from one sector to another;

    identifying and updating parameters including location update information uniquely identifying a sector from which the at least one client is receiving communication service;

    determining at least one geographically dense call group;

    choosing at least one designated responder to respond to the at least one call group;

    computing clusters of clients with related parameters; and

    selecting at least one client per cluster as a designated responder for that cluster and when the server needs to set up a geographically dense group call, a random number is included corresponding to the designated responder for that group in a call setup message.
