Abstract

A method for operating a wireless messaging system, the messaging system being configured to comprise a plurality of mobile wireless clients (1, 1′, 1″), a core messaging system (7) and at least two gateway processes or gateways (5, 5′, 5″) acting as proxies on behalf of the clients (1, 1′, 1″), the method comprising, in order for a client (1) to establish a connection with one of the gateways (5, 5′, 5″), a two phase connect procedure with the steps of, the client (1) maintaining a list of access points, each access point defining an address at one of the gateways (5, 5′, 5″); the client (1) sending, over a wireless bearer (4, 4′, 4″), a phase one connection request to one of the access points; the gateway (5, 5′, 5″) that is addressed by the phase one connection request, sending, in response to the phase one connection request, over a wireless bearer (4, 4′, 4″), a list of connect points to the client (1), each connect point defining an address at one of the gateways (5, 5′, 5″); the client (1) sending, over a wireless bearer (4, 4′, 4″), a phase two connection request to at least one of the connect points; and the gateway (5, 5′, 5″) that is addressed by the phase two connection request responding to the phase two connection request, and the client (1) establishing a connection with the gateway (5, 5′, 5″) specified by said connect point.

Claims14

Dependent claims

A method for operating a wireless messaging system, the messaging system being configured to comprise a plurality of mobile wireless clients, a core messaging system and at least two gateway processes or gateways, the gateways acting as proxies on behalf of the clients and in the course of normal operation of the messaging system maintaining sessions by performing the steps of,

the gateways receiving inbound messages from the clients over a wireless bearer using a wireless protocol and forwarding said inbound messages to the core messaging system over a connection using a wirebound protocol;
the gateways receiving outbound messages from the core messaging system over a connection using a wirebound protocol and forwarding said outbound messages to the clients over connections using a wireless protocol;
the method comprising, in order for a client to establish a connection with one of the gateways, a two phase connect procedure with the steps of,
the client maintaining a list of access points, each access point defining an address at one of the gateways;
the client sending, over a wireless connection, a phase one connection request to one of the access points;
the gateway that is addressed by the phase one connection request, sending, in response to the phase one connection request, over a wireless bearer, a list of connect points to the client, each connect point defining an address at one of the gateways;
the client sending, over a wireless bearer, a phase two connection request to at least one of the connect points;
and
the gateway that is addressed by the phase two connection request responding to the phase two connection request, and the client establishing a connection with the gateway specified by said connect point.

6 more elements

A wireless messaging system, the messaging system being configured to comprise a plurality of mobile wireless clients, a core messaging system and at least two gateway processes or gateways, the gateways acting as proxies on behalf of the clients and comprising a client session manager for, in the course of normal operation of the messaging system, maintaining client sessions by

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;
receiving outbound messages from the core messaging system over a connection using a wirebound protocol and forwarding said outbound messages to the clients over a wireless bearer using a wireless protocol;
the wireless messaging system further comprising, in order for a client to establish a connection with one of the gateways, a distributed logic for implementing a two phase connect procedure, said distributed logic comprising:
in the client, a client library providing an application program interface for, among others, accepting, access points, each access point defining an address at one of the gateways;
in the client, the client library comprising a phase one routine for sending, over a wireless bearer, a phase one connection request to one of the access points;
in the gateway that is addressed by the phase one connection request, a servlet for sending, in response to the phase one connection request, over a wireless bearer, a list of connect points to the client, each connect point defining an address at one of the gateways;
the client library also comprising a phase two routine for sending, over a wireless bearer, a phase two connection request to at least one of the connect points;
and
the gateway that is addressed by the phase two connection request comprising a response logic for responding to the phase two connection request, and for establishing a connection between the client and the gateway.
