Abstract
Method and apparatus for dealing with a connection context request to establish a connection between a mobile station (MS) and a network gateway element. The gateway (such as a GGSN) determines whether binding information is required, then ascertains whether such information has been supplied. If the information is not supplied, the GGSN responds to the request on the bas is of a policy determined by the operator of the network. This can include, for example, rejecting the request.
