Patent ID: 7464178

Claim:
A messaging gateway comprising: a network node layer including modular network nodes for interfacing with mobile devices of a plurality of different communication standards to receive content or service requests from the mobile devices and to route responses to the mobile devices; a gateway node layer including modular gateway nodes for routing the requests and the responses and for modifying the requests and responses according to device technology and content attributes; an application access node layer including modular application access nodes for accessing content servers and application servers; an API framework for creating network, gateway, and access nodes; and wherein the network nodes: manage context for a device making a request, and convert an input into a Web request using input data, device context, and application context; add user and location context to requests; translate responses into a device-specific format using response data, device context, and application context; update and store context between device interactions; include a plurality of adapters, each said adapter associated with a type of mobile device and sheltering application servers and content servers from device capabilities; and wherein the gateway nodes provide a series of configurable routing, validation, and filtering functions that provide content and routing management of messaging traffic that passes through the gateway node layer, and in which the service provided by the gateway node layer is determined by a path taken through said gateway nodes, and in which: the gateway nodes control access to Web applications according to user subscriptions, in which responses are split up and routed according to adapter capabilities, content attributes, and user-specified rules, a filter gateway node processes messages and forwards them in a structured manner, its functionality allowing it to modify or delete a message, a router gateway node has functionality for routing messages to other nodes according to message contents, gateway parameters, gateway loading, service context, and address information, and the gateway nodes include database gateway nodes for accessing a database.
