Wireless unit status notification system for a communication

A status notification system is implemented on a wireless network. In a standard manner, a network user initiates a communication to a 'recipient' unit at the user's 'source' wireless unit. If the call is unanswered, information relating to the status of the recipient unit is obtained and transmitted for display on the source unit. The displayed status might be 'busy,' 'in a meeting,' or the like, as determined by the system and/or as designated by the user of the recipient unit. The status information may be obtained from the recipient unit, by referencing a database record, or by determining the operational condition of the recipient unit. In another embodiment, when the status of a wireless unit changes, or when the user of the wireless unit changes a designated status, the change in status is transmitted to each wireless unit listed on a 'buddy list' for the user.

Generating initial copy in replication initialization

The present invention provides a mechanism for generating an initial copy in replication initialization. A request is received to replicate a source volume from a source node to a target node so as to generate the initial copy of the source volume in the target node. With respect to a current source data block of at least one source data block contained in the source volume, a search in the target node is performed for a target data block corresponding to the current source data block. Responsive to identifying the target data block, the initial copy of the source volume in the target node is updated using the target data block with the information from the current source data block.
