A method, computer program product and computing device for selecting at least one playlist for transfer, the at least one playlist being stored on a first personal media device. The at least one playlist is converted to a common format, thus generating a first common format playlist. Communication is established with a second personal media device. The first common format playlist is transferred to the second personal media device.

A switch device is provided. The switch device includes a switch and a one-way link circuit, wherein the switch including a first port, a second port, and a third port. The third port coupled to the second port via a first path and coupled to the first port via a second path. An input terminal of the one-way link circuit is coupled to the first port.

Systems and methods for managing a Network Based Media Processing (NBMP) workflow are provided. A method includes obtaining, from a descriptor corresponding to a network based media processing (NBMP) workflow, or a task included in the workflow, a syntax element indicating a protocol characteristic of a protocol corresponding to an input or an output of the workflow or the task, deriving the workflow based on the task; and managing at least one media processing entity according to the derived workflow, wherein the protocol characteristic relates to at least one from among a nonessentiality, a timing, an order, a number, a latency, and a size associated with the input or the output.

Techniques are described to support call routing and location for a user equipment (UE) with satellite wireless access to a serving PLMN. The UE sends a Session Initiation Protocol (SIP) INVITE message to a network node, such as a P-CSCF, that includes an indication of satellite access for the UE. In response the network node sends a request to another network node for a cell ID for a fixed cell in which the UE is located. The fixed cell can be independent of satellite radio cells for the serving PLMN. The network node may receive the cell ID for the fixed cell and sends the SIP INVITE message to another network node (e.g., an E-CSCF or LRF) with the cell ID for the fixed cell. The other network node may use the cell ID to route the SIP INVITE message or obtain an approximate location of the UE.

A method of establishing a Voice over Internet Protocol, VoI P, call between a calling User Equipment, UE, and a called UE, wherein said calling UE is served by a core network via a packet-switched radio access network, PS-RAN, and wherein a bearer is to be established between said calling U E and a gateway node in said core network, over said PS-RAN, for obtaining access to an Internet Protocol, IP, multimedia subsystem, I MS, network, wherein said method comprises the steps receiving, by a an IMS Call Session Control Function, CSCF, node a notification message thereby notifying said I MS node that said VoIP call establishment is in progress and initiating, by said I MS CSCF, re-establishment of said bearer between said calling UE and said gateway node, over said PS-RAN, in case said establishment of said bearer has failed due to a temporary failure.

A method performed within a communication system comprising a 5G core network and an IP Multimedia Subsystem (IMS) network, where the 5G core network is configured to implement a plurality of virtual core network slices each having a slice identifier. The method comprises assigning one of said virtual core network slices to a User Equipment (UE) at or following registration of said UE with the IMS network, and sending from the UE or the 5G core network, to the IMS network, the slice identifier of the network slice assigned to the UE. The method further comprises receiving the slice identifier within the IMS network and storing in the IMS network a mapping between the UE and the received network slice identifier. The slice identifier is used within the IMS network to provision services to the UE.
