A mobile communications system includes switching between communication paths based on the quality of service. A VoIP service is coupled to a mobile network and a wireless local-area network (WLAN) via a wide-area IP network. A plurality of mobile communications devices are associated with VoIP telephone numbers. A public switched telephone network (PSTN) is coupled to the plurality of mobile communications devices and coupled to the VoIP service. A quality of service server is coupled to the plurality of mobile communications devices via the wide-area IP network for determining the quality of data channels to a mobile communications device via the mobile network and to the mobile communications device via the WLAN. A voice call is carried over one of the mobile network, the WLAN, and the PSTN depending on the quality of the data channels.

An example communications system for providing communication services between communications devices may employ multiple usage rates for metered communication services. A method for adjusting usage amounts to account for multiple usage rates may include determining a usage adjustment factor for a communications event; determining a metered usage amount for the communications event; and determining an adjusted usage amount based on the usage adjustment factor and the metered usage amount for the communications amount. Thus, a billing system in the communications system may determine an invoice amount based on the adjusted usage amount and a predetermined bill rate.

A computer-implemented billing method including displaying, on a video call screen, video data related to a counterpart terminal with which a video call is connected, recognizing reaction information input from the counterpart terminal based on the video data related to the counterpart terminal displayed on the video call screen, and generating billing data related to the recognized reaction information of the counterpart terminal based on a billing policy may be provided.

Systems and methods for initiating communication with a controlled-environment facility resident by a non-resident may employ a controlled-environment facility secure communication platform that receives an incoming communication request from a non-resident, directed to a telephone number assigned to a controlled-environment facility resident and/or a controlled-environment facility media and/or communications device associated with the resident, for a communication with the resident. The facility secure communication platform sends an event notice to the device associated with the resident or a controlled-environment facility media and/or communications terminal associated with the resident, in response to receipt of the incoming communication request. The device or terminal presents an option to accept the event notice and the controlled-environment facility secure communication platform and/or the device or terminal connects an outgoing communication from the device or terminal to a device associated with the non-resident, in response to acceptance of the event notice.

An incoming communication processing system and method is disclosed for providing communication and data services to residents of a controlled facility. Specifically, the incoming communication processing system allows outside parties to initiate communications to residents of a controlled facility. The incoming communication processing system may work in conjunction with or separately from an outgoing communication processing system. Many restrictions and safeguards may be implemented within the incoming communication system in order to prevent improper use.

Multiple factor authentication of a user is provided by verifying a first authentication factor for the user. At least one target endpoint device is identified relative to the user. An application program interface (API) is accessed and used to generate a communication request that includes a first portion specifying the target endpoint device and written in a format of an application program interface (API), and a second portion that includes a set of one or more documents written in a programming language that includes call flow commands for call routing logic of a call control server. The call flow commands include commands specifying how to communicate a security code. The communication request is transmitted to the call control server. Input is received from the user. A second authentication factor is verified for the user by comparing the input to the security code.

Methods and systems for independent security scrubbing and billing of calls through an IP Multimedia Core Network Subsystem (IMS) are provided. The system includes a core IMS network and a security network cloud securely connected via session border controllers. The IMS network is configured to route calls to the security network cloud. The security network includes call-processing and billing servers that implement security checks on calls from OSI model layer three to seven and analyze the call to collect and generate billing data. After successful security and billing operations, the call is routed back to the IMS network for handling according to conventional workflows. Accordingly, the disclosed invention serves to enhance security for IMS traffic, improve the accuracy of customer billing and conserves IMS network resources which would otherwise be consumed by malicious attacks and billing responsibilities.

The present invention provides an IP telephone and the like capable of preventing a loss of the beginning part of a talk. A communication apparatus according to the present invention includes: a memory (110) configured to store communication data with a communication destination; and a control unit (120) configured to transmit and receive the communication data to and from the communication destination in each first duration and store the transmitted and received communication data in the memory (110), then output, after a communication session with an external recording apparatus that records the communication data is established, the communication data stored in the memory (110) to the external recording apparatus in each second duration that is shorter than the first duration.

Systems and methods for reducing fall back from long term evolution voice calls (VoLTE) to legacy systems. The system can include one or more lookup tables including ranges of internet protocol (IP) addresses for a plurality of user equipment (UE). The lookup tables can be stored on one or more network entities, such as on a proxy call session control function (PCSCF). In the event that a policy charging rules function (PCRF) is unable to establish a Gx session with the relevant packet gateway (PGW), the PCSCF can provide the name and/or the IP address for the appropriate PGW to the PCRF. The PCRF can then send a session request AVP to the IP address to cause the PGW to initiate Gx binding. The system enables VoLTE calls to be established despite problems with the PCRF and reduces fallback to legacy systems.

A database stores unique associations between account identifiers and mobile-network telephone numbers assigned by a mobile network to mobile communications devices. The account identifiers are also associated with voice-over-IP (VoIP) telephone numbers. Voice calls between the mobile communications devices are made as voice-over-IP (VoIP) calls using respective VoIP telephone numbers. Tracking of the VoIP calls is performed through the mobile network using respective mobile-network telephone numbers, so that a prepaid balance can be enforced.
