A method and arrangement for remotely controlling the communication of media between devices in different local networks (200, 202) using a remote control device (200b). The remote control device obtains discovery information on a first device (200c) and sends a remote access request over a multimedia service network to a home multimedia gateway (202b) in the opposite local network (202) for a connection to a second device (202c) therein. The home multimedia gateway then responds with communication parameters established for the second device in a residential gateway, and the remote control device can then order the first device to execute a multimedia session with the second device by using said communication parameters. This solution enables a remote control device visiting a local network to order a device in that network to fetch media content from a device in another home network, or vice versa.

Users receiving incoming messages may provide their preferences for how they wish to be notified of the incoming messages. A plurality of user devices may be caused to output indicators of the incoming messages, and at least one of the user devices may also provide an acknowledgement of the notification, and the indicators may be cleared.

Methods, systems, and apparatus, including computer programs, providing resilient SCTP stack operation. One method includes having a master and slave for a gateway, the master checkpointing key protocol state, including: for transmissions over an SCTP connection from an application to a peer, checkpointing the message payload when a message is received from the application and before it is pushed to the SCTP protocol; after transmitting data to the peer, checkpointing a stream ID, stream sequence number, and transmission sequence number (TSN) of each chunk; and on receiving a selective acknowledgement (SACK) that a chunk was received, deleting the chunk and checkpointing this deletion; and for receptions of data: on receiving a chunk from the peer, checkpointing a message payload, stream ID, stream sequence number, and TSN before sending a SACK; and upon delivery of a message to the application, deleting the message from the SCTP stack and checkpointing the deletion.

A communication system for an organization having multiple sites uses a dual-mode device capable of both cell phone communication and telephone communication on a local area network (LAN). IP LANS are established at organization sites such that a temporary IP address is assigned to a dual-mode device that logs onto an organization LAN, and the IP address is associated at a PSTN-connected server on the LAN with the cell phone number of the communication device. The IP server notifies a PSTN-connected routing server when a device logs on to a LAN, and also provides a destination number for the IP server. Cell calls directed to the device are then redirected to the IP server and directed to the device connected to the LAN.

A symmetric flow response path from an Autonomous System (AS) can be forced by using a same edge gateway for ingress and egress of communications with an Internet source. An asymmetric flow response path from an AS can be used by using different edge gateways for ingress and egress of communications with an Internet source. An anycast IP address can be used for selecting egress edge gateways of an AS. Packets in an AS can be redirected to selected egress edge gateways of the AS.

The present invention is directed to methods, apparatus and systems for optimizing media paths in communications networks. An exemplary embodiment includes the steps of a first SBC (SBC1) receiving a session request including a SDP offer for a session between first and second devices including media stream(s), said request being sent by a second SBC (SBC2) and traversing a portion of a signaling path including intermediary device(s), determining that media stream(s) should bypass one or more of the intermediary device(s), generating and transmitting to SBC2 from SBC1 a SDP answer including at least one of: (i) all SDP media descriptor transport addresses being set to zero; (ii) all SDP media stream connection values being set to 0.0.0.0 and at least one media transport address being non-zero; or (iii) header information or SDP information indicating that at least one intermediary device should be bypassed for the one or more media streams.

Systems and methods to selectively block calls from reaching destinations based on an input received from a callback connection. One embodiment includes a web server to receive a selection of an advertisement from an customer and to obtain a communication reference from the customer in response to the selection; a session border controller to interface with a packet switched network; and one or more telecommunication servers coupled to the session border controller and the web server, the one or more telecommunication servers to establish a connection for real time communications using the communication reference, to initiate a connection for real time communications with an advertiser of the advertisement after receiving an indication of acceptance of the connection established using the communication reference; where the advertiser is charged an advertisement fee in response to establishing a connection for real time communications between the advertiser and the customer.

Various embodiments of the present technology allow multi-realm support at I/S-CSCF to IMS by the same I/S-CSCF nodes. Some embodiments allow for a registration message to be received from an IMS client. The registration message can be used to establish, through an Internet Protocol Multimedia Subsystem (IMS) core network, a service between a first endpoint associated with a first realm and a second endpoint associated with a second, different realm. The registration message can be translated so that the second endpoint believes the first endpoint is associated with the second realm before being transmitted to the second endpoint. Upon receiving a successful IMS registration message from the IMS core network, a binding can be created between the first endpoint and the second endpoint.

A first SBC establishes a first media session between a transferor and a transferee. A second SBC establishes a second media session between the transferor and a transfer target. The first SBC receives a REFER message initiated by the transferor and determines that a dialog ID in the REFER message does not correspond to a media session currently being handled by the first SBC. The first SBC sends a SIP INVITE message to a plurality of SBCs, including the second SBC, that are in a load sharing group with the first SBC. The SIP INVITE message includes the dialog ID associated with the second media session, which triggers the second SBC to re-use the second media session to establish a media session between the transferee and the transfer target.

Systems, methods, and computer-readable media are provided for managing mutual and transitive trust relationships between resources, such as Fog/Edge nodes, autonomous devices (e.g., IoT devices), and/or analog/biological resources to provide collaborative, trusted communication over a network for service delivery. Disclosed embodiments include a subject resource configured to assign an observed resource to a trust zone based on situational and contextual information. The situational information may indicate a vector of the observed resource with respect to the subject resource. The contextual information may be based in part on whether a relationship exists between the subject resource and the observed resource. The subject resource is configured to determine a trust level of the observed resource based on the determined trust zone. Other embodiments are disclosed and/or claimed.
