Abstract: In an embodiment, an Internet Protocol (IP) multimedia subsystem (IMS) network that is operated by a single operator receives a request from a user equipment (UE) for registering to a group IMS session. The IMS network determines a location region where the UE is located and identifies a single application server deployed in the location region at which to register UEs that are located in the location region and request registration to the group IMS session. In another embodiment, an application server deployed in a first location region receives a request to register a UE to an IMS session from the IMS network. The application server selectively redirects the registration for the UE either to (i) an application server deployed in a second location region, or (ii) another application server deployed in the first location region.

Abstract: In an embodiment, a server registers each of the plurality of client applications on the same client device. The server receives a given registration request message from the client device that includes a request for renewing a registration for a first of the plurality of client applications with the server, and the server renews the first client application's registration in response to the given registration request message. The server also determines, in response to the given registration request message, whether to preemptively renew registrations for one or more other client applications from the plurality of client applications. The server selectively renews the registrations for the one or more other client applications based on the determination.

Abstract: In an embodiment, a server registers first and seconds client applications on the same client device. The first client application on a client device obtains, from the server or some other source, application-to-application communicative information for facilitating communication between the first and second client applications. Based on the application-to-application communicative information, the first client application configures a given registration request message that includes (i) a request for renewing the first client application's registration with the server, and (ii) a request for renewing the second client application's registration with the same server, and transmits the given registration request message to the server. The server renews the registrations for the first and second client applications in response to the given registration request message.

Abstract: The various embodiments provide a framework for using a server to create and maintain equivalence classes among applications operating on multiple devices that have registered with the server. In the various embodiments, the server may use equivalence classes to select an application on a target device (the “recipient application”) that has the highest probability of being able to receive shared media from an application operating on the originator device (i.e., the “originator application”) based on the recipient application's similarity to the originator application. The various embodiments further enhance privacy protections and the overall user experience by enabling the server to select an appropriate recipient application on the target device without the originator device or its user having to know anything about the target device's characteristics and functionalities.

Abstract: Devices, systems and methods for sending messages from a web service server to a computing device shared by a current user and another offline user while maintaining privacy for the other offline user's messages and decreasing bandwidth requirements for transmission of messages may include registering the user and the offline user of the computing device with the web service server, receiving at the web service server from the computing device a login by a first user, wherein the first user is determined to be the current user, checking a database for undelivered messages for the at least one offline user who is not currently accessing the web service server, wherein any user who is not a current user is determined to be an offline user, encrypting each offline user's undelivered messages, sending the undelivered messages to the computing device, and storing offline user encrypted undelivered messages in the computing device.

Abstract: The disclosure is directed to obtaining metadata related to a target of a short uniform resource locator (URL). An embodiment transmits the short URL to a server, receives a response from the server, wherein the response includes a pointer to an actual URL, requests metadata related to the actual URL from the server, and receives the metadata for the actual URL from the server. An embodiment confirms a target of a short URL. The embodiment receives the short URL, obtains metadata related to an actual URL based on the short URL, extracts a host website from the metadata, determines whether the actual URL points to the host website, and sends a notification of a result of the determination.

Abstract: Systems, methods, and devices of the various embodiments enable dynamically creating and joining group communication sessions without (i.e., “free of”) operator-controlled or operator-assisted provisioning. By encoding group call provisioning information in a bar code, such as a Quick Response Code (“QR code”), that participants can scan using their mobile communication devices (e.g., smart phones), a group call may be created and provisioned on communication devices. The QR code encodes the information needed to initiate and/or join a group communication session maintained by a group communication server.

Abstract: The disclosure relates to wireless communications. An aspect generates a plurality of packets of data, each packet comprising a header and a payload of media data, receives opaque data related to a payload of at least one packet, and embeds the opaque data in an extension header of the at least one packet. An aspect receives a plurality of packets of data, each packet comprising a header and a payload of media data, and receives opaque data related to a payload of at least one packet, the opaque data embedded in an extension header of the at least one packet.

Abstract: A hybrid-padding approach for arranging variable size data packets for error correction encoding and decoding is disclosed. The approach can involve arranging the data packets in columns and rows and selecting the row size to minimize the amount of padding required. If data packet is smaller than the number of rows the data packet is inserted into the column and the remaining rows are padded. If the data packet is larger than the number of rows, the data packet is allowed to span multiple columns with the last column being padded if necessary. The data packets can include parameters, such as a source block number, packet length, and starting column number, and the error correction packets can include parameters, such as, a source block number an N, a K, the starting column number, and the number of row, to signal the hybrid-padding message.
