Disclosed are apparatuses and methods for location area update. An example method may include transmitting a first request to establish a radio link, the first request including information on a first location area update, transmitting a second request to execute the first location area update via the radio link, and releasing the radio link in response to at least one status of an access stratum feedback to the second request. Related apparatuses and computer readable medium are also disclosed.

A procedure for initial registration of a UE and a procedure for periodic registration or registration based on movement, and a communication means are provided which are used to implement Network Slice Specific Authentication and Authorization in 5GS. Furthermore, by providing the Network Slice Specific Authentication and Authorization initiated by a network, a procedure for changing UE configurations initiated by the network, the procedure being initiated based on completion of the Network Slice Specific Authentication and Authorization, a de-registration procedure initiated by the network, and a communication means, a communication means is provided that is used to implement functions related to the Network Slice Specific Authentication and Authorization in the 5GS.

A presence server in a network can receive capability information about a UE in a publish message, and make that capability information available to other UEs on the network. When the UE later deregisters from the network, the UE can send an unpublish message. However, the presence server can at least partially disregard the unpublish message and continue to make the capability information about the UE available to other UEs. The presence server can also filter capability information of one or more target UEs provided to a watcher UE based on a registration status of a target UE, capabilities of the watcher UE, and/or whether a set of target UEs associated with a single user share certain capabilities.

A system and method, for identification of the user equipment with IMS PDN connectivity issues, and proactively recovering the PDN connectivity for said user equipment is disclosed. The disclosure provides triggering the System initiated detach with re-attach required request, to user equipment by checking the current IMS PDN state of said VoLTE user equipment to recover the IMS PDN connectivity. The present disclosure provides a novel automatic method for maintaining IMS PDN connection providing continuous voice call connectivity and improving the overall connectivity and user experience of the wireless network.

Techniques are disclosed relating to temporary networks of edge computing devices. In some embodiments, an edge computing device manages, in response to occurrence of an event, a temporary network of edge computing devices. Managing the temporary network includes: forming the temporary network, managing membership of edge computing devices in the temporary network, causing the temporary network to perform a specified set of tasks, transmitting, to a remote server computing system, information associated with the specified set of tasks, and causing disbanding of the temporary network after determining that the specified set of tasks is complete. The disclosed techniques for managing temporary networks of edge computing devices may advantageously reduce the overall use of a network's bandwidth by reducing the amount of communication with a remote server system.

One or more computing devices, systems, and/or methods are provided. In an example, a group member list is received in a device, and a group reporting schedule is received in the device. Reporting data is communicated by the device using the group reporting schedule. A group exit message is sent by the device responsive to determining a group exit condition associated with failing to detect communications from group members specified in the group member list.
