摘要： A call contention manager mediates between call contentions that occur when two callers attempt to place a telephone call to one another at approximately the same time. The call contention manager may be implemented in or separate from a mobile switching center. The manager detects a call contention between two calls, and it determines whether the call contention is taking place in a window of time that follows shortly after at least one of the callers was involuntarily dropped from a call. If a call contention occurs within such a call drop window, it is resolved according to a post-drop protocol that enables a connection between the callers. If, however, the call contention occurs outside any call drop window, it is resolved without establishing a connection between the callers, for example by sending one or more of the contending calls to voicemail.

摘要： A method, device, and system for re-routing an incoming call via a stronger serving system. When a wireless communication device such as a cell phone is receiving an incoming call via a first serving system with which it is registered, the device may detect that a second serving system (possibly a competing carrier's system) would provide improved signal strength. In response, the device may prompt its user to request the call be re-routed to the device via the other serving system. If the user approves, the device may then signal to the network to cause the call to be re-routed to the device, and the device may register with the new serving system. That way, as the network sets up the call to the device again, the call will extend via the new (improved signal strength) serving system to the device, thus reducing the likelihood of a call drop.
