Abstract: A method and apparatus for remotely performing tasks in a wireless personal digital assistant (PDA) by a user is provided. A user can perform tasks, such as, retrieving information and locking the PDA, by sending a controlling or special SMS message to the PDA. The special SMS message has a predetermined format which describes at least a task required and a user-input password. According to the needs of the task, the special SMS message may also include a source or an identifier from which the information is to be retrieved, and a destination to which the retrieved information is to be sent. The retrieved information may be sent as an SMS message or an electronic mail message or both.

Abstract: A method for user processes, each having a unique user identification code, to intercommunicate within a communication management system even if one of the user processes is unavailable, comprises the following steps: associating an agent process with a particular user identification code in order to correspond to a user process having the particular user identification code; determining whether the user process is available in the communication management system; causing the agent process to log into the communication management system with the particular user identification code when the user process is unavailable; and enabling the agent process to intercommunicate with user processes within the communication management system instead of the unavailable user process by using the particular user identification code of the unavailable user process.
