A method and apparatus for processing message is described. In one embodiment, an application programming interface is configured for receiving and sending messages. A multiplexer receives messages from different servers. A service name is coupled to each message with the corresponding destination service. A single shared channel is formed. The messages are processed over the single shared channel.

Message handling multiplexer

A method and apparatus for processing message is described. In one embodiment, messages are received over a plurality of channels from a plurality of applications in a virtual machine. An identifier is coupled to each message. The identifier refers to the application originating the corresponding message. A shared transport is formed and associated with the channels. The messages are processed with the shared transport with the identifier.

Shared transport

Methods and systems are provided for controlling asynchronous distribution and installation of software updates affecting applications installed on terminal devices of a wireless network. A versioning schema enforced by the application development environment enables the runtime environment of a terminal device to evaluate a software update to identify potential compatibility issues and control installation of the update.

Method and system for controlling software version updates

Wireless data message optimization for messages sent between a wireless device and a server that provides a service that the wireless device is authorized to access is provided using an application gateway that serves as a proxy between the wireless device and the server. The application gateway maps optimized service request messages generated by the wireless device to a service request message format expected by the server, and maps response messages generated by the server to an optimized response message format expected by the wireless device. The optimized message format is flattened by removing unnecessary message structure, eliminates unnecessary message fields, and uses default and enumeration encoding to reduce optimized message size.

System, method and apparatus for optimized wireless messaging

A method and apparatus for processing messages is described. In one embodiment, an application programming interface provides for a flush protocol to force members of a group to send all of their pending messages prior to a predetermined event. A client sends a request to a coordinator of the group to join the group and to transfer a state of the group to the client. The application programming interface performs a single flush operation on the group in response to the request.

Combined join and state transfer

A method is disclosed for upgrading preexisting application data according to a new application definition, the method comprises parsing the preexisting application data to provide parsed preexisting application data and converting the parsed preexisting application data according to the new application definition to thereby provide application data compliant with the new application definition.

Method for upgrading application data according to a new application definition

A method and apparatus for processing message is described. In one embodiment, an application programming interface is configured for receiving and sending messages. The application programming interface provides for a flush protocol to force members of a group to send all of their pending messages prior to a predetermined event, and to perform a message exchange phase as part of the flush protocol to allow all members of the group to see a same set of messages in a same view prior to installing a new view.
