A server is configured to provide data communications services to a plurality of endpoint devices. Geolocation information identifying a first geographic location of the particular endpoint device is received at the server and from an application running on an endpoint device. A second geographic location for an IP address is compared to the first geographic location. In response to a mismatch between the compared geographic locations, a location database is modified to include an entry specifying that the particular endpoint device is located at the first geographic location. For an outgoing telephone call from the endpoint device, the modified entry is used to select a telephone carrier. The outgoing telephone call is routed using the selected telephone carrier.

The disclosure relates to methods and system for handling immersive services with feature tags in an 3GPP IP multimedia subsystem (IMS) and 3GPP mission critical services (MCX). A user equipment uses the media tags, feature tags with unique IMS communication service identifier (ICSI) and IMS application reference identifier (IARI) to communicate with the IMS network for determining the immersive services in the communication. Accordingly, a method includes: performing, a registration with a network for handling immersive call services based on feature tags included in a session initiation protocol (SIP) REGISTER request; determining whether the network provides a provision for the handling of immersive call services based on an SIP REGISTER response; and sending an SIP INVITE request including feature tags to a second client device via the network based on determining that the network provides the provision of handling immersive media streams. Thus, the immersive call is established by the first client device with the second client device.

A system for data recording across a network includes a session border controller connecting incoming data from the network to an endpoint recorder. A load balancer is connected to the network between the session border controller and the endpoint and receives the incoming data from the session border controller, wherein the load balancer comprises computer memory and a processor configured to parse the incoming data into video data and audio data according to identification protocols accessible by the processor from the computer memory. A recording apparatus includes recording memory that receives the incoming data from the load balancer, stores a duplicate version of the incoming data in the recording memory, and connects the incoming data to the endpoint.

A method of operating a network server, such as a mobile application gateway, connect devices on a cellular or carrier network with individual networks, such as enterprise voice and data networks or residential networks. The effects of the present invention are far reaching in terms of transferring effective call control from the cellular network into the control of the individual network, such as the enterprise, and enabling new business models for the purchase of cellular service from a public cellular carrier by an enterprise.

A system and method to provide multimedia services to consumption end devices like set-top boxes and legacy phone and tablet devices that are incompatible to receive the multimedia service directly. These consumption devices interact with devices that provide multimedia service. Further, the present disclosure discloses mechanisms where an end consumption device can connect to a device like LTE connectivity device and obtain eMBMS multimedia services.

Various embodiments of the present technology allow multi-realm support at US-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 method, device and medium for determining a coding format are provided. The method includes: receiving one or more data packets forwarded by a call center during a VoLTE communication, in which the one or more data packets carry a first coding format; detecting whether the first coding format is same with a negotiated second coding format; and modifying the coding format used during the VoLTE communication from the second coding format to the first coding format, if the first coding format is not same with the negotiated second coding format.

A User Equipment (UE) registers with a Long Term Evolution (LTE) network. The UE registers with an Internet Multimedia Subsystem (IMS) over the LTE network. The UE registers with a Wireless Fidelity (WIF) network. The UE receives a status request from the LTE network responsive to a Session Initiation Protocol (SIP) invite for the UE received at the IMS. The UE transfers a status response to the LTE network that indicates the WIFI network responsive to the status request. The UE receives the SIP invite from the IMS over the WIFI network. The UE exchanges user data for the media session over the WIFI network.

A terminal receiving a push message is provided. The terminal sets service control condition which specifies application identifier (app ID) corresponding to service that the terminal is allowed to receive, wherein the service control condition is contained in push message control policy. And the terminal then receives a push message, matching the push message control policy, sent by a server.
