Techniques are disclosed to determine one or more specific data points that may be found in or added to call metadata that will assist and/or enhance confidence score algorithms. A call request for an inbound VoIP telephony call may be received by a telephony server in a servicing telecommunications carrier network. The call request may be intended for a called party serviced by the servicing telecommunications carrier network. The servicing telecommunications carrier network telephony server may obtain a plurality of data points associated with the call request wherein at least one of the data points is an interconnect carrier, the interconnect carrier data point identifying which carrier handed the call to the servicing carrier. The servicing telecommunications carrier network telephony server may then send the plurality of data points to a confidence score generating process comprising an algorithm configured to determine a confidence score using the data points. The servicing carrier telephony server may then receive the confidence score from the confidence score generating process and pass the confidence score to the called party.

Techniques for using call metadata as an indicator for calling party authenticity

Techniques are described for determining when and how to re-route toll-free calls around a core telephony network experiencing significant disruptions. A core telephony network of a telephony service provider is monitored for anomalies. Upon detecting an anomaly, it is determined whether the anomaly is significant enough to warrant re-routing inbound toll-free calls around the core telephony network. The re-routing process comprises accessing an industry registry database including a plurality of toll-free numbers (TFNs) associated with a routing template comprising the instructions for routing toll-free calls. The routing template instructions may be switched to re-direct toll-free calls associated with one or more specific TFNs to a particular carrier. Within that particular carrier, the routing instructions may be switched to re-direct the toll-free calls away from the service provider's core telephony network to a network bypass cloud platform. The network bypass cloud platform may be configured to receive toll-free calls, determine a customer telephony network to which to route the received toll-free calls based on the TFN of the toll-free call, and route the toll-free call to the customer telephony network.

Methods, systems, and computer readable media for unifying fixed and mobile devices via third party call control (3PCC) are disclosed. The method is performed at a dedicated application server (AS) that supports a third-party call control (3PCC) interface. According to one method, a call addressed to a unified subscriber identifier associated with a terminating subscriber is detected, where the terminating subscriber is associated with two or more terminating endpoints. The call is offered to each of the terminating endpoints by initiating signaling to each of the terminating endpoints using the 3PCC interface. One of the terminating endpoints used to answer the call is detected and the call is redirected to the terminating endpoint used to answer the call. Signaling messages are sent to all of the terminating endpoints other than the terminating endpoint used to answer the call for instructing the terminating endpoints to release resources associated with the offered call.

The present invention provides a technique for providing a forced hold service such as is used for an emergency services call, which is supported at least in part over a packet network. The forced hold service acts to effectively hold a connection for the call with a called party, even when the caller takes an action that would normally end a call, such as going on hook, pressing end, or the like. When the caller takes an action that would normally end the call, the forced hold service allows the caller to automatically reconnect to the emergency services provider over the held connection upon going offhook, pressing send, or the like. Alternatively, the emergency services provider can effectively re-engage the call wherein the caller is reconnected over the held connection upon going offhook, pressing send, or the like.

Forced hold call handling in a VoP environment

Mid-call services may be added to a communication session such as a telephone call (call session) by a wireless device on a mobile telephone network by causing the wireless device associated with the communication session to invoke a second call session directed to a vertical service code. The second call session is established on the wireless communication network and terminated on the PSTN to an application server associated with the vertical service code. The application server on the PSTN instantiates the service and matches the service associated with the vertical service code on the second call session with the first call session. The application server then applies the mid-call service associated with the vertical service code to the first call session to thus enable mid-call services to be applied to the first call session by the wireless device.

The present invention relates to a service broker capable of dynamically provisioning media gateways, gateway controllers, and call servers when adding one or more of these elements to the network, or reconfiguring the network when an element fails or to balance loads. Based on defined guidelines or rules, the service broker can select gateway controllers for media gateways, call servers for gateway controllers, and backup elements for any of the above. Once selected, the service broker notifies all affected elements of their associations.

A system for providing wireline telephone services to wireless subscribers utilizing a packet data networkThe system includes a base station controller (BSC)a base station controller gateway (BGW)for providing client based services to mobile subscribers and providing protocol mapping between a mobile protocol and a packet data network protocol. The system further comprises a mobility gatekeeper (GK)for managing network mobility services for each wireless call including the establishment of a call control path and a speech path between said base station controller and a serving end office telephone point. The system also comprises a end office gateway (EOGW)for providing protocol conversion between the packet data network protocol and the end office point data protocol such that a wireless subscriber has access to all wireline services provided by the end office point. A mobile switching center (MSC)and mobile switching center gateway (MGW)are included to facilitate inter-system call handoffs into an existing circuit-switched wireless telephony network.

The present invention provides an architecture for a media gateway to identify and register with multiple media gateway controllers for various types of voice and data services, along with having the media gateway appear to each of these media gateway controllers as a single, dedicated control entity. A logical layer, referred to as a virtualizer, is associated with each media gateway and appears to the media gateway as a single media gateway controller. To each media gateway controller the virtualizer supports, the virtualizer appears as a single media gateway. In essence, the virtualizer is a protocol manager and message router. The virtualizer supports the registration of multiple media gateways and then creates virtual gateways based on requirements of the media gateway controllers serving these virtual gateways. Preferably, subscribers associated with endpoints handled by the media gateway are grouped into a virtual gateway being served by a select media gateway controller or group thereof.

Dynamic association of endpoints to media gateway controllers

Methods and systems consistent with the present invention perform enhanced services for wireline and wireless subscribers in an integrated wireline and wireless switching system. The enhanced services may include, for example, group dialing plans, message waiting indicator activation, call forwarding, simultaneous ringing, call conferencing, calling line identification, automatic call back, automatic recall, speed dialing services, and/or any other services that may be provided by a switching system to wireless and/or wireline subscribers. When a calling wireline and/or wireless subscriber requests one or more of the enhanced services, the integrated wireline and wireless switching system determines the line types associated with the wireline and/or wireless devices of a called subscriber, and identifies references to one or more shared procedures for performing the enhanced services according to the determined line types without creating direct dependencies between wireline and wireless modules in the integrated wireline and wireless switching system. Finally, the integrated wireline and wireless switching system executes the identified procedures to perform the shared services.

An integrated wireless and wireline telecommunication switch. The switch includes peripheral modules having both wireless and wireline peripheral devices. The switch also includes wireless and wireline software load. An aspect table allows the wireless and wireline software load within the switch to be executed within a single call without creating direct dependencies on each other. The switch allows new and more efficient connections between wireless and wireline subscribers. In many cases wireless and wireline subscribers having direct access to the switch can connect without using any other switches in the network.

Apparatus and method of establishing a call using wireless and wireline integration through a telecommunication switch

A system and method of PSTN based network roaming and SCP based subscriber management for internet telephony systems. When a call is incoming to the central office of a subscriber's home service area which supports packet data network telephony , such as for instance IP telephony, a home location register translates the directory number into an IP address, URL address, or electronic mail address much the same that a local number portability node re-routes calls for non-IP telephony systems. When a subscriber is roaming in another network , the roamed into (visited) gateway signals back to the home location register of the subscriber's network and registers its (i.e., the visited gateway's) public switching telephone network telephone directory number and the IP address assigned to the subscriber while connected to the visited network . When subsequent calls are incoming to the subscriber's home network switch, the home location register provides the ten (10) digit directory number of the visited gateway and the new IP address rather than the home gateway telephone number and IP address of the subscriber.
