Abstract: A computerized push notification distribution system, receives a registration message from a third party application executing on a user's communication device. The registration message includes a push notification service registration identifier from a push notification server and a user identifier of the user. The computerized push notification distribution system stores the push notification service registration identifier and the user identifier linked to the third party application. Upon receiving from a third party a message content for a push notification to users of the third party application, the computerized push notification distribution system generates and transmits to the push notification server a request for transmitting a push notification, for each notification service registration identifier linked to the third party application, each request includes the message content for the push notification and the respective notification service registration identifier.

Abstract: For generating one or more two-dimensional visual objects, an initial visual representation is determined (S2) and shown (S3) in a display area of a communication terminal (1). A data representation of the visual objects is transmitted (S5) from the communication terminal (1) to a remote processing center (3). The communication terminal (1) receives (S7) from the processing center (3) an enhanced visual representation of the visual objects, and replaces (S9) in the display area the initial representation with the enhanced representation. Retrieving (SE) an enhanced representation from the processing center (3), makes it possible to display visual objects on the communication terminal (1) in representations which are not supported by the communication terminal (1), e.g. graphical objects can be rendered according to enhanced algorithms and/or characters can be rendered in enhanced fonts not supported by the communication terminal (1).
