UEs can determine a codec to use for a call based on a codec priority list. A UE can dynamically determine a priority order for the codec priority list based on call conditions experienced by the UE, such that a low bitrate codec may be indicated as the highest priority on the codec priority list if the UE is experiencing relatively poor call conditions. The UE that receives the codec priority list can select a codec from the codec priority list to use during the call. The UE that receives the codec priority list may select one of the listed codecs based on call conditions experienced by that UE, such that the UE may select a low bitrate codec due to relatively poor call conditions being experienced by that UE even if the low bitrate codec is not identified on the codec priority list as the highest-priority codec.

Methods and systems for an intelligent network protection gateway (NPG) and network architecture are provided. According to one embodiment, a firewall provides network-layer protection to hosts of a private network against unauthorized access by hosts of an external network by performing network address translation (NAT) processing of Internet Protocol (IP) addresses. The firewall also provides application-layer protection on behalf of the hosts and supports Voice over IP (VoIP) services by processing signaling protocols associated with VoIP sessions. An external VoIP interface of the firewall receives incoming VoIP packets each associated with a VoIP port of the external interface. The packets are directed to an appropriate host by the firewall performing port address forwarding based on a mapping of VoIP ports to private addresses of the hosts.

Network resources for a call are allocated. The network resources for the call are reserved based on a reservation. The network resources are reserved before any one network resource is committed. If the call is confirmed, then the network resources are committed.

Technology for a local user equipment (UE) operable to perform video conferencing with a remote UE is disclosed. The local UE can define a region of interest (ROI) within a field of view of a camera of the remote UE. The local UE can map the ROI to one or more pan, tilt, zoom and focus (PTZF) commands. The local UE can send the one or more PTZF commands to the remote UE, wherein the remote UE is configured to identify the ROI based on the one or more PTZF commands. The local UE can receive encoded video within the ROI from the remote UE. The encoded video can include the regions within the ROI at an increased zoom level while substantially maintaining a defined quality level to enable the encoded video within the ROI to be rendered and displayed at the local UE.

An apparatus and method are disclosed for migrating between terminals. An apparatus that incorporates teachings of the present disclosure may include, for example, a network proxy having a controller that manages a communications interface in a communication system. The controller can be programmed to receive a request to migrate a first terminal to a third terminal while active communications are taking place on a first voice channel connecting the first terminal to a second terminal, establish a second voice channel with the third terminal, connect the first and second voice channels, and terminate without action of an end user of the first terminal a connection between the first terminal and the first voice channel. Additional embodiments are disclosed.

A system, server, and method of DTMF detection in a VoIP network.

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.

Systems and methods for controlling communication systems for the hearing impaired are disclosed. A portable communication device requests control over a plurality of communication devices. The portable communication device connects to and controls the plurality of communication devices. The portable communication device includes a user interface that enables a user to transfer a call from a first communication device to a second communication device.

Additional embodiments are disclosed.

One aspect includes a method of operating a user terminal adapted for wireless telecommunications using any of a plurality of different radio access technologies including a Circuit Switched, CS, access and a Packet Switched, PS access. The PS access includes access via a Long Term Evolution, LTE, network and WiFi access via a Wireless Local Area Network, WLAN. The method includes: (i) making a determination to switch from a PS LTE access to a WiFi access, (ii) switching to WiFi access, and (iii) ignoring or rejecting a command received to hand over to a CS access. Other aspects include a user terminal, a telecommunications network entity, and a method of operating a telecommunications network entity.
