Abstract

See full text

A method is disclosed for managing the communication of data packets between a mobile data radio terminal and a plurality of fixed base stations in a data communications network. In a system of a plurality of base stations (each including a set of cellular telephone voice transceivers), wherein a first and second base stations are coupled through a home mobile data gateway (MDG) to the data communications network and a third base station is coupled through a server mobile data gateway to the data communications network, a method and apparatus which establishes in the home mobile data gateway, a forwarding address to a server mobile data gateway, sends forwarding information from the home mobile data gateway to the server mobile data gateway, and allocates with the server mobile data gateway, a new channel at the third base station, for the mobile data radio terminal. The method further includes determining which base station is providing better signal measurement data and allocating with the home mobile data gateway, a new channel at the better base station, for the mobile data radio terminal. The method further includes allocating an additional channel to the mobile data radio when the forward data packet size is greater than a threshold value. Further in accordance with the invention, when the system receives a forward data packet at the home mobile data gateway from the data communications network, directed to the mobile data radio terminal, it sends the forward data packet to the server mobile data gateway.
