Abstract: A method, system and apparatus for managing persona-based notifications at a communication device are provided. A port is dynamically assigned to an application on the basis of a persona at a communication device, the application enabled to receive notifications from a given provider. The port is registered with a server to receive the notification. The port is opened to receive notifications associated with the persona for the application from the server.

Abstract: A method is disclosed for reducing setup latency in commencing data exchange between two devices seeking to exchange data across a networked data channel. Control messages are exchanged across a control channel while establishing the data channel according to a protocol. The control messages contain some of the data to be exchanged. The remaining data is exchanged across the data channel once established. The data both in the control messages and exchanged across the data channel may be tagged with a file transfer identifier to facilitate reconstruction of the data at the receive end. If data encryption is desired, the data in the control messages may be encrypted by the sender with a temporary key and a shared key may be established by the devices. Once the key has been established, the temporary key may be encrypted with the shared key and exchanged across the data channel to permit decryption of the data in the control messages at the receive end.
