Abstract: An improved method, apparatus, and computer instructions for writing a page of data in response to receiving a request to write the page in the paged memory system. Creating a version of the page of data in response to receiving the request to write the page in the paged memory system, and associating a version identifier with the version of the page.

Abstract: The present invention is a novel and improved method for providing broadcast short message services (SMS) in a communication network. It is an objective of the present invention to provide a method and apparatus that insures the successful transmission of the broadcast message while minimizing the impact of providing the short messaging service on overall system capacity. It is further the objective of the present invention to provide a method and apparatus for receiving broadcast messages without depriving the receiver of the benefits of slotted paging, that being the savings in power consumption.

Abstract: Method and apparatus for encrypting transmission traffic at separate protocol layers L1, L2, and L3 so that separate encryption elements can be assigned to separate types of transmission traffic, which allows the implementation of different levels of encryption according to service requirements. Encryption elements use variable value inputs, called crypto-syncs, along with semi-permanent encryption keys to protect from replay attacks from rogue mobile stations. Since crypto-sync values vary, a method for synchronizing crypto-syncs at the mobile station and base station is also presented.

Abstract: An instant messaging client presents messages and removes the messages from display after a predetermined amount of time. In one preferred embodiment, the predetermined amount of time is agreed upon by all participants during a policy negotiation. Each message may be associated with a display time and when the current time differs from the display time by a predetermined amount, the message is removed from the display. Messages may also be presented in a non-editable display area to prevent manual logging of the messaging content.

Abstract: An instant messaging client disables logging of the session through screen capture. The mechanism detects when the instant messaging client application loses focus or when key sequences that might cause the application to lose focus, or may be associated with screen capture, are encountered. When the text messaging application releases focus or a predetermined key sequence is encountered, the mechanism removes the contents of the instant messaging conversation.

Abstract: Methods, systems, and media are disclosed for a computer-implemented method for improved messaging between devices, which are local or remote to each other. One example embodiment includes a first device, having a first set of messaging preferences, receiving a second set of messaging preferences from a second device, such as a computer having instant messaging capabilities, in communication with the first device. Further, the example embodiment includes comparing the sets of messaging preferences to yield results showing if any conflicting messaging preferences exist between the devices. If conflicting messaging preferences exist, then the devices may negotiate in order to remove such conflicting messaging preferences. Further still, the example embodiment includes determining whether to commence the messaging based on the existence of any conflicting messaging preferences and by enforcing the possibly re-configured messaging preferences during a messaging session.

Abstract: A service platform in a communications network connects callers to a service resource platform when implementing services requiring specialised resources. A number of different services use a common service resource platform. The service platform is programmed with respective maximum values for the number of calls originating from each service that may be connected to the service resource platform at one time and allows the call to be connected to the service resource platform at one time and allows the call to be connected to the service resource platform only when the count value for the respective service is less than the maximum count value. The service resource platform may have a single network address and a common range of ports that are freely allocated to calls generated by the different services running on the service platform.

Abstract: An impact mechanism having a rotating cage member that supports at least one hammer for imparting impacts upon an anvil. More particularly the present invention relates to a cage member of an impact mechanism wherein each hammer pin is supported in a partial bore hole in the end of the cage member closest to the motor of the impact mechanism.
