The method performed by a gateway between a LAN and a WAN that includes a platform of the VoIP telephone service, is characterized in that it includes a step of activating the VoIP telephone service on detecting a connected state of a terminal connected to the gateway.

The present invention is directed to communications methods and apparatus for efficiently distributing traffic to processing entities. An exemplary method includes the steps of: receiving, at a first Session Initiation Protocol (SIP) load balancer (SLB), a first SIP INVITE message; selecting, at the first SLB, which Session Border Controller (SBC) in a first cluster of SBCs to send the first SIP invite message based on a message allocation weight determined based on message loss information corresponding to different SBCs in the first cluster of SBCs, the selecting including allocating a portion of incoming received SIP INVITE messages to an individual SBC based on a message loss rate corresponding to the individual SBC and the message allocation rate, said selecting including selecting a first SBC from the first cluster of SBCs to send said first SIP INVITE message, and sending the first SIP INVITE message to the first SBC.

A packet processing method includes receiving, by an aggregation gateway, a first tunnel establishment request message sent by a home gateway, and sending a first tunnel establishment success message to the home gateway; receiving, by the aggregation gateway, a second tunnel establishment request message sent by the home gateway, and sending a second tunnel establishment success message to the home gateway; associating, by the aggregation gateway, a first tunnel with a second tunnel according to an identifier of the home gateway; and sending a downlink packet to the home gateway by using the first tunnel and/or the second tunnel. The embodiments of the present application may increase bandwidth.

Systems, devices, and technical methods of the present disclosure use an edge appliance to facilitate seamless interoperability between a cloud emergency call management system and call-center systems that are situated onsite in an emergency call center. When an emergency call is received from a caller device, the CECMS routes the call to a call taker who may be working remotely on a telecommunication device. The CECMS transmits a duplicate of audio data and other data that is exchanged between the caller device and the telecommunication device during the call to the edge appliance. The edge appliance converts the audio data and the other data into formats that are compatible with the call-center systems and uses a virtual construct that represents the telecommunication device to transmit the converted data to the call-center systems through a network to which both the edge appliance and the call-center systems are connected.

A gateway device that connects a PSTN network to an IP network includes a signal conversion unit that extracts information necessary for ISUP service provision from information included in a received ISUP signal, and generates an SIP signal in which the information is set in the header, a determination unit that determines whether to relay the header for a connection destination device on the basis of a type of a connection destination device and terminal conditions of an outgoing terminal and an incoming terminal that are set in the ISUP signal, and a relay unit that relays the SIP signal to a connection destination device in a case of relaying the header, and transmits an SIP signal from which the header has been deleted to a connection destination device in a case of not relaying the header.

Systems and methods include a cloud hub located in a premises, and the cloud hub comprises adapters configured for coupling to premises devices. The cloud hub is configured as a gateway for the premises devices. The system includes a virtual gateway located in a cloud server environment and coupled to the cloud hub. The virtual gateway is configured as a server-side abstraction of the cloud hub. The cloud hub and the virtual gateway are configured as an automation platform that maintains state data of the premises devices, controls interaction among the premises devices, and monitors and manages the premises devices.

Novel tools and techniques for providing an in-line AI virtual assistant are provided. A system includes a session border controller coupled to an end-user device, and a session initiation protocol stack. The session initiation protocol stack includes a processor, and non-transitory computer readable media comprising instructions executable by the processor to: receive, from the session border controller, a call invite request; provision, via the AI virtual assistant service, an AI virtual assistant instance in response to the call invite request; and join the AI virtual assistant instance to a call with the end-user device.

Techniques for a selection or reselection a user-plane path in a mobile network are disclosed herein. A user-plane gateway (GW-U) can be configured to decode a packet received from a control pane gateway (GW-C) is a packet data network gateway (PGW) to determine a forwarding policy. Additionally, the GW-U can decode, from an evolved node B (eNB), an internet protocol (IP) packet having a header field. Furthermore, the GW-U can determine a user-plane path for the IP packet based on a comparison of the header field and the forwarding policy. Based on the determined user-plane path, the GW-U can forward the IP packet to a local application server (AS), encapsulate and forward the IP packet to the PGW, or discard the IP packet. Moreover, the GW-U can encode the IP packet for transmission based on the determined user-plane selection.

Embodiments of a method performed by an Interconnect Border Control Function (IBCF) in an Internet Protocol (IP) Multimedia Subsystem (IMS) network and corresponding embodiments of an IBCF are disclosed. In some embodiments, the method performed by the IBCF comprises receiving, from an IMS node in a virtual IMS network domain of a virtual IMS network operator, a Session Initiation Protocol (SIP) message that serves as a request for a leased IMS service. The SIP message comprises information that identifies the leased IMS service, information that identifies an IMS network slice, information that identifies the virtual IMS network operator, information that identifies one or more sub-services requested for the leased IMS service, and/or information that identifies an IMS network slice instance. The method further comprises making a decision as to whether to accept or reject the request based on the information comprised in the SIP message.
