Abstract
A system and method for concurrently ringing a subscriber's wired and mobile stations, where the wired station is served by a wired telecommunications network and the mobile station is served by a wireless telecommunications network. The call is routed to a network interface point of control from either the wired or wireless networks and the network interface becomes the point of control for the call. The call is initially offered to the mobile station by the network interface point of control, and before the mobile station rings, the call is offered to the wired station so that the wired and mobile stations ring concurrently.
Claims31
A method of routing a call such that a called party's first station and second station ring concurrently, the method comprising:
- (a) routing the call to a network interface point of control;
- (b) offering the call from the network interface point of control to the first station;
- and
- (c) delaying offering the call from the network interface point of control to the second station for a predetermined time.
A telecommunications system for concurrently ringing a plurality of stations upon receiving a call, the telecommunications system comprising:
- a network interface point of control connected to the plurality of stations, the network interface point of control offering the call to a first station of the plurality of stations and delaying, for a predetermined period of time, offering the call to a second station of the plurality of stations.
A network interface point of control within a telecommunications system for concurrently ringing a plurality of called party's stations, comprising:
- an interface switch for providing switching of voice paths between stations;
- and
- a controller for controlling the interface switch to offer a call to a first station and to delay offering the call to a second station for a predetermined period of time.
A method of routing a call such that a plurality of stations associated with a called party ring concurrently, the method comprising:
- (a) routing the call to a network interface point of control;
- and
- (b) offering the call from the network interface point of control to each of the plurality of stations at predetermined different times.
A network controller that controls concurrent ringing of plural communication devices including a wireless communication device and a wired communication device, wherein the network controller delays offering of a call to the wired communication device after offering of the call to the wireless communication device to compensate for an offering time difference between the wired communication device and the wireless communication device.
A computer-readable medium storing computer-executable instructions for causing a network interface point of control programmed thereby to perform a method of controlling concurrent ringing of plural communication devices including a wireless communication device and a wired communication device, the method comprising:
- delaying relaying a call to the wired communication device after relaying the call to the wireless communication device to offset a call setup time difference between the wired communication device and the wireless communication device.
A network controller that controls concurrent ringing of plural communication devices including a wireless communication device and a wired communication device, wherein the network controller delays offering of a call to the wired communication device for a predetermined time after offering of the call to the wireless communication device.
A computer-readable medium storing computer-executable instructions for causing a network computer system programmed thereby to perform a method comprising:
- relaying a call to a wireless communication device;
- delaying relaying the call to a wired communication device to offset a call setup time difference between the wireless communication device and the wired communication device;
- and
- relaying the call to the wired communication device, whereby the wireless communication device and the wired communication device ring concurrently.
A network computer system comprising:
- means for offering a call to a wireless communication device;
- means for delaying offering of the call to a wired communication device to compensate for a ring initiating time of the wireless communication device;
- and
- means for offering the call to the wired communication device, whereby the wireless communication device and the wired communication device ring concurrently.
