A method for carrier network integration through a user proxy interface includes receiving a request from a mobile device associated with a subscriber of a carrier provider to establish voice services with the carrier provider for a companion device linked to the mobile device. The request includes a subscriber identifier of the mobile device. The method also includes authenticating the companion device based on the subscriber identifier, obtaining session initiation protocol (SIP) credentials corresponding to the subscriber identifier, and registering the SIP credentials for the companion device at a network interface proxy. The network interface proxy is in communication with an internet protocol multimedia subsystem (IMS) of the carrier provider and the companion device. The method also includes establishing voice services between the companion device and the IMS through the network interface proxy using the SIP credentials.

Video-assisted presence detection is used to enhance a user experience in telephony communications. Image data, video data, or both, from a camera are used to determine whether a user is present at their device before a call is transferred to him or her. The video-assisted presence detection can be implemented based on a privacy setting. For example, one implementation allows a system to have partial access to the camera to perform a scan to detect that there is a human present without capturing facial information, and without identifying that person. Another implementation allows the system to have partial access to the camera to scan the a face of a user, but not have access to the video feed of the camera. Another implementation allows the system to have full access to the camera.

A method for controlling devices to present content includes: determining content to be presented in response to a content request event occurring; determining a content presentation form supported by a presentation device; and providing corresponding presentation content to the presentation device in accordance with a determined presentation form. As such, the current content presentation form can be determined based on the content presentation forms supported by the presentation device, and the content in different presentation forms can be continuously presented, thereby enhancing the user experience.

Methods, systems, and/or devices for media context switching among electronic devices are described herein. In one aspect, a method is performed at a first electronic device. A first media item is played. While playing the first media item, a near-field-communication (NFC) channel is established with a second electronic device while the second electronic device is playing a second media item. First contextual data of the first electronic device is transferred via the NFC channel to the second electronic device, wherein the first contextual data corresponds to the first media item. A playback command for the second media item is received. In response to receiving the playback command for the second media item, the first electronic device plays the second media item.

A wireless communication network enforces a user policy for a User Equipment (UE) and directs another wireless communication network to enforce another user policy for another UE. In the wireless communication network, an Application Function (AF) receives the user policy from another AF in the other wireless communication network and transfers the user policy to the PCF. The PCF distributes the user policy to a Network Function (NF). The NF enforces the user policy. The PCF identifies the other user policy for the other UE and transfers the other user policy to the AF. The AF responsively transfers the other user policy to the other AF. The other AF transfers the other user policy to another PCF in the other wireless communication network. The other PCF distributes the other user policy to another NF in the other wireless communication network which enforces the other user policy.

A first server system is configured to communicate with a first client device through a first application executing on the first client device. The first server system determines that communication with the first client device through the first application has been lost due to the first client device entering an idle mode. The first server system receives a request from a second client device that triggers reestablishing communication with the first client device through the first application. In response, the first server system transmits a request to a second server system to wake the first client device from the idle mode. The first server system receives, from the first application on the first client device, an indication that communication has been reestablished between the first server system and the first application. The first server system transmits a control command to control the first client device.

Technologies are disclosed for providing stream media content and/or metadata indicating stream media content. A media control device may receive a Digital Living Network Alliance (DLNA) hypertext transport protocol (HTTP) request from a media content device. The DLNA HTTP request may have a header created by the media content device. The media control device may interpret the DLNA HTTP request header. A first metadata may be identified in the DLNA HTTP request header that may indicate a request for stream media content information. The media control device may send a DLNA HTTP response to the media content device. The DLNA HTTP response may have a header that may include a second metadata indicating the stream media content information. The second metadata may include information enabling construction of a HTTP Live Streaming (HLS) master playlist, a program map table, and/or a program association table associated with the stream media content.

In some embodiments, communication and/or media user interfaces associated with a synchronized media and communication session can be displayed at one or more devices. In some embodiments, a first electronic device can join and/or add media content to a synchronized media and communication session when an associated second electronic device is part of the synchronized media and communication session.

A call control entity communicates with Internet Protocol (IP) phones. The call control entity creates a mapping between a headset identifier of a headset connected to a registered first IP phone, and an identifier associated with the first IP phone. Upon receiving a request from a second IP phone that is not registered, the call control entity determines there is no existing IP phone record for the second IP phone. Responsive to the determining, the call control entity acquires from the second IP phone the headset identifier, and accesses an first IP phone record of the first IP phone based on the headset identifier and the mapping. The call control entity creates a second IP phone record for the second IP phone, copies existing configuration information from the first IP phone record to the second IP phone record, and configures the second IP phone with the existing configuration information.

A method for changing a communication network for video communication is provided. The method includes performing, by a user equipment (UE), video communication through a mobile communication network; searching for whether there is a wireless local area network (WLAN) accessible by the UE; displaying, if a WLAN accessible by the UE is found, the accessible WLAN; and when the displayed WLAN is selected by a user, changing a communication network for the video communication to perform the video communication through the selected WLAN.
