Abstract: A centralized polling system is set forth for providing constant time select call functionality to a plurality of polling tasks in an operating system kernel. In one aspect, the CPS registers for and thereby captures events of interest on a continual basis. Polling tasks are supplied with active events thereby eliminating the need to repetitively poll large numbers of inactive sockets. An exemplary embodiment of the CPS includes a system interface to the operating system kernel, a data structure for maintaining a profile for each of the polling tasks, and an application programming interface for registering the polling tasks, receiving the active sockets and corresponding read/write event types via the system interface, updating the profile within the data structure for each of the polling tasks, and returning the current read and write ready sockets to respective ones of the polling tasks.

Abstract: A system and method of controlling the delivery of an incoming call directed to a wireless communication device is provided. When an incoming call directed to the wireless communication device is received, the location of the wireless communication device, to which the incoming call is destined, is determined. If the wireless communication device is not within a designated zone, the incoming call is directed to the wireless communication device. If the wireless communication device is in a designated zone, the incoming call is handled based on specified criteria.
