Claims
- 1. In a wireless communication system comprising a Base Station connected with a mobile unit, a method of synchronizing at least one neighboring Base Station to the Base Station connected with the mobile unit comprising:
from the Base Station connected with the mobile unit, sending call parameters and rough synchronization information to the at least one neighboring Base Station; and at the at least one neighboring Base Station, monitoring transmissions of at least one of:
the Base Station connected with the mobile unit; the mobile unit; and a beacon signal from a beacon transmitter which is within range of the at least one neighboring Base Station and the Base Station connected with the mobile unit.
- 2. Method, according to claim 1, wherein the mobile unit is a device selected from the group consisting of:
telephone handset, standard cordless telephone handset, cellular telephone handset, personal data device, personal digital assistant (PDA), computer, laptop computer, e-mail server, a device utilizing point-to-point protocol (PPP) to the Internet via a central remote access server, a headset, a personal server, a wearable computer, a wireless camera, and a mobile music player.
- 3. In a wireless communication system comprising a Base Station connected with a mobile unit, a method of detecting and synchronizing with the mobile unit prior to receiving a handoff of a session with the mobile unit, comprising:
from the Base Station connected with the mobile unit, sending rough synchronization information to at least one neighboring Base Station; at the neighboring Base Station, performing a wide-range search for “target” signals having the correct timing for a mobile unit, based on the rough synchronization information provided by the Base Station which is connected with the mobile unit; narrowing the search for an actual signal from the mobile unit; acquiring the target signal; and synchronizing the neighboring Base Station to the Base Station connected with the mobile unit.
- 4. Method, according to claim 3, wherein:
the mobile unit is equipped with a short-range wireless communication transmitter/receiver.
- 5. Method, according to claim 3, wherein the mobile unit is a device selected from the group consisting of:
telephone handset, standard cordless telephone handset, cellular telephone handset, personal data device, personal digital assistant (PDA), computer, laptop computer, e-mail server, a device utilizing point-to-point protocol (PPP) to the Internet via a central remote access server a headset, a personal server, a wearable computer, a wireless camera, and a mobile music player.
- 6. Method, according to claim 3, further comprising:
providing communication links between the Base Stations, wherein the communication links between the Base Stations are selected from the group consisting of RF links and land lines; and transferring connection status information and rough synchronization information between the Base Stations over the communications links.
- 7. Method, according to claim 3, wherein:
the Base Stations and the Switch are connected via a wired or wireless local area network (LAN).
- 8. Method, according to claim 3, wherein:
the wireless communication system comprises a wireless private branch exchange (WPBX) handling calls from mobile units comprising handsets.
