The invention provides a way to fallback to a PSTN call at any time during a VoIP call when Quality of Service in a VoIP network falls below some acceptable level. The PSTN fallback calls can be retrieved “midcall” and rerouted back over the VoIP network. This provides optimal utilization of VoIP without sacrificing the quality of the call connection. Calls are cheaper because PSTN fallback calls are only established temporarily for the amount of time that the QoS problem exists on the VoIP network. Call fallback is conducted in a VoIP gateway by first receiving an incoming call. A Voice over IP (VoIP) call is established for the incoming call over the VoIP network. VoIP packets are encoded from the voice signals in the incoming call and sent over the VoIP network. Quality of service of the VoIP network is monitored during the VoIP call and a fallback call is setup over a PSTN network at any time during the VoIP call when the monitored quality of service of the VoIP network degrades. For a time the voice signals from the incoming call are cross connected to both the output for the fallback call and the output for the VoIP call. When a destination gateway starts receiving the voice signals from the fallback call, the VoIP call is dropped. The quality of service on the VoIP network continues to be monitored during the fallback call. A new VoIP call will be reestablished over the VoIP network during the fallback call when the quality of service of the VoIP network improves. Voice from the incoming call is for a time again cross connected to both the fallback call and the new VoIP call. After the destination gateway starts receiving audio packets again over the new VoIP call, the PSTN fallback call is terminated.

A telecommunications service controls and monitors telephone calls by storing at a service control point (SCP) restricted telephone numbers and priority telephone numbers. Upon receiving call data relating to a call between a subscriber telephone number and an outside telephone number, the SCP determines whether the outside telephone number matches the restricted or priority telephone numbers. When the outside telephone number matches a restricted telephone number, the call is terminated and the SCP stores the call data. When the outside telephone number does not match a restricted telephone number, or matches a priority telephone number, the call is connected. The SCP transmits stored call data to a service management system, which is accessible by the subscriber via the Internet or an interactive voice response, for generating reports. The service further includes time schedules for implementing call restrictions and personal identification number for bypassing call restrictions.

A technique for detecting SPAM calls in VoIP networks and taking responsive actions to such calls is described. Detection is based on recognizing abnormalities in signaling message statistics. For example, a device that persistently sends many more call setup requests then it receives and at the same time constantly receives too many, or too few, call terminations in a statistically determined period of time is assumed to be a spam source. This criteria is based on the principle that a Spammer originates many calls, which are consistently terminated by the Spammer or by the recipient. Responsive actions to the detection of VoIP spam may include displaying a call text warning to the recipient, using special ring tone, automated voice mail answer, rejecting the call, etc. The invention addresses an issue that will become more problematic for VoIP networks and their subscribers in the future, and to which a solution has not been proposed in the prior art.

Various systems and methods for servicing emergency calls are disclosed. One such method includes providing a location database that includes physical location information about a communication device.

Automatic notification is provided to pre-designated emergency contacts for a given wireless subscriber upon the occurrence of an emergency call from the subscriber. Triggering for the automatic notification may take place at an appropriate time in the emergency call, e.g., at a time the emergency call is received, at a time during the emergency call after a current location of the emergency caller is obtained by the emergency network, once the emergency call terminates, after a set amount of time after the emergency call is received, terminates, etc. The automatic notification is preferably made using voice over Internet Protocol (VoIP), but may instead be pre-designated by the subscriber to be in an alternative mode, e.g., by SMS, switched telephone, etc. An option is included for the emergency caller to cancel the automatic notification. The location of the emergency caller may be configurably provided to a notified emergency contact.

The present invention provides a method and apparatus for restricting call terminations for a roaming mobile unit. A serving MSC, which is an MSC providing call processing a mobile unit that is not the home MSC of the mobile unit, sends a registration notification request to the home location register (HLR). The HLR retrieves the termination access code parameter from the HLR and sends it to the serving MSC. The termination access code parameter includes a value that indicates if the mobile unit is allowed to roamer port calls. The parameter is stored at a VLR associated with the serving MSC. When a call request comes in to the serving MSC and requests a roamer port call with the mobile unit, the serving MSC checks the value of the termination restriction code to determine if it should terminate, or complete, the call.

Voice mail service in an environment having multiple voice mail technology platforms is provide by an Automatic Message Attendant (AMA) device and a subscriber profile database.

Additionally, the AMA device may also have a greeting player and message recorder element that queries an announcement database, and a content adapter element that queries a message format requirement database. Thus, the AMA device may also provide call termination functionality by playing a greeting and recording a message from the caller, and converting the recorded message into a format suitable for use with the selected voice mail technology platform.

A telecommunications system and method is disclosed for notifying a called subscriber of call terminating treatment applied by the network to calls unable to be completed to the called subscriber at the terminal associated with the originally dialed called party number. When a call to a called subscriber is not completed to the called subscriber, the network logs call information, such as the calling party number, calling party name (if available) and the date and time the call was received. In addition, the network also logs call treatment information, such as the called party number that the call was forwarded to, an indication of whether or not the call was completed to the forwarded to number, an indication that the network was busy or an indication that the called mobile subscriber could not be located. This call information and call treatment information is later provided to the called subscriber.

A telecommunications service controls and monitors telephone calls by storing at a service control point (SCP) restricted telephone numbers and priority telephone numbers. Upon receiving call data relating to a call between a subscriber telephone number and an outside telephone number, the SCP determines whether the outside telephone number matches the restricted or priority telephone numbers. When the outside telephone number matches a restricted telephone number, the call is terminated and the SCP stores the call data. When the outside telephone number does not match a restricted telephone number, or matches a priority telephone number, the call is connected. The SCP transmits stored call data to a service management system, which is accessible by the subscriber via the Internet or an interactive voice response, for generating reports. The service further includes time schedules for implementing call restrictions and personal identification number for bypassing call restrictions.

The present invention relates to wireless telephone networks, and more particularly to the allocation of radio channels to calls in CDMA-based systems when their Radio Access Networks (RAN) are congested. A Base Station (BS) receives a call origination from a mobile device. The BS communicates information about the call and about its radio availability to a Mobile Switching Center (MSC). The MSC determines the priority of the call and how the call should be treated by the BS based on the supplied information. The MSC communicates the treatment information and the priority information back to the BS. When the RAN is congested, high-priority calls are queued. These high-priority calls are served based on allocation specification in which radio channels may be assigned to low-priority calls, which are not queued, while there are still calls in the queue.
