A communication device and system are disclosed for providing communication and data services to residents of a controlled facility. The device can be restricted to communicating only using an internet protocol so as to restrict the device communication to an internal intranet. Wireless access points may be disposed throughout the environment to route calls and data between the device and a central processing center. By converting a protocol of the communications received from the device to a protocol used by the central processing center, minimal modifications to the central processing center are needed to support a wireless communication infrastructure. Many restrictions and safeguards may be implemented within the phone and system in order to prevent improper use.

The present invention relates to a system which enables users to use call capabilities of their mobile second numbers over a device wherein their first numbers are included without carrying a second device by means of a mobile application in a mobile IMS (IP Multimedia Subsystem) network.

A terminal device 1 collects RTP information related to a call and transmits the RTP information to a CSCF 3. The CSCF 3 collects, from a plurality of SIP packets related to the call, the address of an edge router 2 that has handled the plurality of SIP packets, the address of an SBC 4 that has handled the plurality of SIP packets, and the domain name of an operator's network 5 that has handled the plurality of SIP packets, and stores in a call information list, for each call, the collected information in association with the RTP information transmitted from the terminal device 1. Then, the CSCF 3 identifies a plurality of problem-occurring calls using the RTP information, and determines a faulty portion based on a bias in the quantitative trend of the count of each of the edge router 2 addresses, the count of each of the SBC 4 addresses, and the count of each of the operator's network 5 domains.

Providing a user experience on a multimodal communications terminal configured to communicate according to a plurality of communication includes: executing a single application that provides a user experience (UX) for controlling user selection of preferences of the plurality of communication methods when originating or receiving communication sessions; and providing, via the single application, a selectable control that is persistent such that the selectable control is displayed in any screen of the single application, wherein the control allows selection of one of the plurality of communication methods to use for a particular communication session.

A method for handing over a call from a first communication network to a second communication network, comprising the steps of: registering, by a first mobile client, in particular, an IP-PBX VoIP client, running on a mobile device, the mobile device with an IP-based PBX for the first communication network, following a naming convention, by sending a registration message from the first mobile client to the IP-based PBX, the registration message comprising an endpoint ID, establishing an active conversation over the first communication network, detecting, on the mobile device, a connectivity change with respect to the first communication network, wherein the further steps of retrieving, by the first mobile client, the status of the call impacted by the connectivity change, and subsequently transferring the call to the second communication network are carried out using SIP NOTIFY messages. Further, a communication system for carrying out the method is provided.

In various embodiments, an electronic device comprising a communication circuit, a processor, and a memory is disclosed. The memory may store instructions that, when executed, cause the processor to transmit, to a network, a first session initiation protocol (SIP) invite message including at least one dummy value by using the communication circuit, obtain channel state information by using the communication circuit, determine a codec for performing a packet based call on the basis of channel state information, and transmit, to the network, a second SIP invite message including information of the determined codec by using the communication circuit. Various other embodiments are also possible which are known from the specification.

A telecommunication network associated with a wireless telecommunication provider can be configured to transmit application data using different quality of service (QoS) specifications. In some configurations, data, other than voice and video data, can be transmitted using VoLTE or ViLTE data streams. According to some examples, network hardware and/or software (e.g., in the core network of a telecommunications network), and/or an application on the UE (smartphone, tablet, etc.) may translate data to be compatible with the VoLTE or ViLTE specifications. The translated data is transmitted from the device to the telecommunications network as a VoLTE or ViLTE packet stream. The converted packets may be identified (e.g., a unique digital signature) so that the corresponding hardware and software in the MSO can identify that a stream of VoLTE or ViLTE packets is to be converted back into the native format of the application before being routed to a destination.

Methods and apparatuses for managing spoofed calls to a mobile device are described, in which the mobile device receives a call transmitted over a cellular or mobile network. The call may include a set of information associated with the network, such as a geological location of a device that generated the call, a hardware device identifier corresponding to the device, an internet protocol (IP) address associated with the device, or a combination thereof. The mobile device may determine whether the call is spoofed or genuine based on the set of information. Subsequently, the mobile device may assist a user of the mobile device to manage the call, such as blocking the call from reaching the user, informing the user that the call is spoofed, facilitating the user to report the call as spoofed to an authority and/or a service provider of the network.

A device, method, and system provide for collecting service parameters associated with application sessions associated with a plurality of MEC clusters; obtaining capability information associated with each of the plurality of MEC clusters; generating service profiles for a set of transport networks based on the service parameters and the capability information, wherein each transport network includes at least one of the plurality of MEC clusters; receiving, from a user equipment (UE) device, a request for a MEC service having a minimum service requirement; and selecting, based on the service profiles, a MEC cluster from the plurality of MEC clusters to provide the MEC service, wherein the selected MEC cluster is included in a first transport network that meets the minimum service requirement.

A method for HTTP stream tuning during load and overload control includes, at a first NF, determining a load/overload level of the first. The method further includes determining an initial value for an HTTP SETTINGS_MAX_CONCURRENT_STREAMS parameter. The method further includes publishing the initial value of the HTTP SETTINGS_MAX_CONCURRENT_STREAMS parameter to a second NF that sends traffic to the first NF. The method further includes determining that the load/overload level of the first NF has changed. The method further includes, in response to determining that the load/overload level has changed, adjusting the value of the HTTP SETTINGS_MAX_CONCURRENT_STREAMS parameter based on the load/overload level and a direction of change in the load/overload level. The method further includes publishing the adjusted value of the HTTP SETTINGS_MAX_CONCURRENT_STREAMS parameter to the second NF.
