Claims
1
A method for operating a gateway for wireless mobile clients in a messaging system, the messaging system being configured to comprise a plurality of mobile wireless clients, a core messaging system and at least one gateway process or gateway, the gateway acting as a proxy on behalf of the clients and, in the course of normal operation of the messaging system, maintaining sessions by performing the steps of,
the gateway receiving inbound messages from the clients over wireless bearers using a wireless protocol and forwarding said inbound messages to the core messaging system over a connection using a wirebound protocol;
the gateway receiving outbound messages from the core messaging system over a connection using a wirebound protocol and forwarding said outbound messages to the clients over wireless bearers using a wireless protocol;
the method further comprising the step of
the gateway storing a session context, which session context comprises the status of a session established between the core messaging system and one of the clients, a state of the client connection associated with the session, and a session identifier which is unique to the session.

A gateway computer for wireless mobile clients in a messaging system, the messaging system being configured to comprise a plurality of mobile wireless clients and a core messaging system, with the gateway computer comprising at least one gateway process or gateway for acting as a proxy on behalf of the clients and, in the course of normal operation of the messaging system, for maintaining sessions by performing the steps of,
the gateway receiving inbound messages from the clients over wireless bearers using a wireless protocol and forwarding said inbound messages to the core messaging system over a connection using a wirebound protocol;
the gateway receiving outbound messages from the core messaging system over a connection using a wirebound protocol and forwarding said outbound messages to the clients over wireless bearers using a wireless protocol;
the gateway further comprising a session manager for storing a session context, which session context comprises the status of a session established between the core messaging system and one of the clients, a state of the client connection associated with the session, and a session identifier which is unique to the session.
