<p>A method and apparatus for establishing data connections between multiple networks is provided. A portable, electronic device 300, such as a mobile telephone, includes a communication module 303 configured to initiate the data connection by transmitting an initiation request. The device 300 establishes the data connection, which may be a packet data protocol-context data connection in a general packet radio service environment, by transmitting an initiation request that includes a network identifier such as access point name to obtain an Internet protocol address. Upon determining available network channels suitable for establishment of the network connection, a processing module 304 selects a corresponding network identifier from a look-up table 305 of network identifiers and corresponding networks. The communication module 303 then transmits the data connection initiation request having the selected network identifier so as to establish a switched packet data connection with the selected network.</p> |
