A method for sharing a reason cause for a mission critical communication (MCX) communication over pre-established session in an MCC network is provided. The method includes transmitting, to the server, a call initiation request to initiate a call, wherein the call initiation request includes first information on a session type and second information on a resource list, receiving, from the server, a mission critical pre-established session control (MCPC) connect message including a security message, determining whether an authentication for the security message is successful, and transmitting, to the server, a first MCPC acknowledgement message including a reason cause field to inform a reason for terminating the call in response to determining that the authentication for the security message is not successful.

A method of dynamic prioritization of collaboration between human and virtual agents according to an embodiment includes generating a priority score for a conversation between a human user and a chat bot, wherein the priority score is based on at least a sentiment of the human user and a temporal aspect of the conversation, providing the priority score to a human agent via an interface for monitoring the priority score, transferring control of the conversation from the chat bot to the human agent based on an interaction of the human agent with the interface, and yielding control of the conversation from the human agent back to the chat bot in response to another interaction of the human agent with the interface.

A method and apparatus of a device that manages a video telephony call is described. In an exemplary embodiment, the device receives a network event from a network service of a device. The device further determines that the network event that is due to a local disruption of a network component of the device. In addition, and in response to the determination, the device restricts a local dynamic control of the video telephony call.

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.

Certain aspects of the disclosure are directed to template-based management of telecommunications services. According to a specific example, a server is provided comprising one or more computer processor circuits configured to interface with a remotely-situated client entity using a first programming language. The server includes a call control engine that is configured to provide a private branch exchange (PBX) for the client entity, and identify a call control template written in a second programming language. The call control engine is further configured to control call routing by the PBX, by executing the call control template to identify at least one data source that corresponds to a call property for the VoIP telephone call, retrieve data from the data source, and implement one or more call processing functions specified by the call control template as being conditional upon the retrieved data.

Apparatuses and methods for P-CSCF to P-CSCF communication are disclosed. In one embodiment, a method implemented in a first proxy-call session control function (P-CSCF) node includes receiving, via a first user plane associated to an Internet Protocol (IP) Multimedia Subsystem (IMS) Protocol Data Unit (PDU) session for a user equipment (UE), a session initiation protocol (SIP) INVITE message; and as a result of the SIP INVITE message and based on a location of the UE relative to a first access gateway (AGW) associated to the first P-CSCF node, determining whether or not to initiate use of at least one of an additional second user plane and an additional second AGW for the IMS PDU session for the UE, the at least one of the second user plane and the second AGW being closer to the UE than the first user plane.

The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. According to one embodiment of the disclosure, terminal access is controlled or terminal access is permitted by using NAS protocol in a 5G communication, and thus a congested situation can be controlled.

An approach is described for facilitating an outbound call from a calling party and a called party by displaying specific information on the communication device of the called party. The displayed specific information is based on a communication characteristic of the called party, where the communication characteristic includes a language characteristic of the called party. Based on language characteristic of the called party, customized display content is provided to the communications device of the called party, on or prior to the called party being alerted to the requested communication. The customized display content improves the answer rate and the conversion rate of the outbound call.
