The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Example embodiments initiate a Mission Critical data (MCData) communication using a pre-established session. A participating MCData server receives at least one pre-established session setup request from an originating MCData client device. The pre-established session setup request comprises the pre-established session indication advising the participating MCData server of initiation of at least one pre-established session. The participating MCData server initiates the at least one pre-established session with the originating MCData client device based on the pre-established session indication. The participating MCData server sends at least one MCData-communication-state message to the originating MCData client device.

The present invention is directed to communications methods and apparatus for efficiently distributing traffic to processing entities. An exemplary method includes the steps of: receiving, at a first Session Initiation Protocol (SIP) load balancer (SLB), a first SIP INVITE message; selecting, at the first SLB, which Session Border Controller (SBC) in a first cluster of SBCs to send the first SIP invite message based on a message allocation weight determined based on message loss information corresponding to different SBCs in the first cluster of SBCs, the selecting including allocating a portion of incoming received SIP INVITE messages to an individual SBC based on a message loss rate corresponding to the individual SBC and the message allocation rate, said selecting including selecting a first SBC from the first cluster of SBCs to send said first SIP INVITE message, and sending the first SIP INVITE message to the first SBC.

A controller includes a real-time communication unit, an application communication unit, and a socket management unit. The real-time communication unit communicates with an external node by using a first socket on a basis of a transmission right map indicating a node possessing a transmission right out of multiple nodes. The application communication unit communicates, not on a basis of the transmission right map, with the external node by using a second socket differing from the first socket. The socket management unit restricts at least one of transmission of information by the application communication unit to the external node and reception of information by the application communication unit from the external node.

A system that incorporates teachings of the present disclosure may include, for example, a computer-readable storage medium in a telephone having computer instructions to execute a web server application in the telephone. The web server application can be operable to detect an incoming plain old telephone service call, identify a calling party identifier from the incoming plain old telephone service call, and direct one of a plurality of devices detected by web server application to present the calling party identifier. Other embodiments are disclosed.

Embodiments may relate to a user equipment (UE) that is configured to determine a real-time transport protocol (RTP) media flow that includes visual data related to a plurality of images concurrently taken of a location and a supplemental information enhancement (SEI) message that is to be used to display at least a portion of the visual data. The UE is further configured to visually display, based on the visual data and the SEI message, the portion of the visual data to a user of the user device. Other embodiments may be described or claimed.

A method, computer program product and computing device for receiving a request to load at least one new media content item on a personal media device. The size of the at least one new media content item is compared with the amount of storage space remaining on the personal media device to determine if the personal media device has sufficient available storage space. If the personal media device does not have sufficient available storage space, a relative weight associated with at least one old media content item stored on the personal media device is ascertained, the relative weight corresponding to a likelihood that the at least one old media content item will be rendered on the personal media device.

A method is provided of managing calls in a voice over IP network, and is performed by a SIP proxy. The method includes receiving a registration request issued by a voice over IP terminal to register with the SIP proxy, obtaining from a database the address of at least one voice over IP platform associated with the voice over IP terminal, registering the SIP proxy with a said voice over IP platform, and sending a request to a number portability server suitable for managing incoming calls to said voice over IP terminal, the request requesting the server to associate the telephone number of the voice over IP terminal with a routing prefix associated with the voice over IP platform.

Aspects of the disclosure are directed to a telecommunications network architecture. In accordance with one aspect, a scalable telecommunications network architecture includes at least one infrastructure switching node; at least one user switching node for receiving a session request, wherein the session request includes at least one user attribute; and at least one controller coupled to the at least one user switching node, the at least one controller for examining the session request a) to allocate at least one bandwidth or at least one data rate for the at least one user switching node based on a resource allocation policy and b) to allocate a quantity of switch elements in the at least one infrastructure switching node based on an interconnection policy. In one example, the at least one controller establishes a communications session for a user terminal based on the session request.

Aspects of the subject disclosure may include, for example, including a processing system for performing operations for determining service requirements of a call session at first user equipment associated with a communication network, determining a first codec to facilitate the call session at the first user equipment according to the service requirements of the call session, searching a session border controller table according to the first codec to obtain a first resource identifier associated with a first session border controller type to facilitate the call session at the user equipment, receiving a first address of a first session border controller associated with the communication network from a domain name server associated with the communication network responsive to a first query including the first resource identifier, and sending a first transport protocol message to the first session border controller according to the first address. Other embodiments are disclosed.
