Embodiments of the present invention relate to a reassociation indication method and apparatus, and a communication device. The method comprises: sending a beacon frame of a multi-transport connection, the beacon frame comprising a reassociation information element; the reassociation information element comprising: indication information used for indicating reassociation request frame transmission.

An object is to provide alternative communication means that does not require establishment of a connection. A communication control device according to the present technology includes: a first communication unit that performs communication by a device designation method that performs signal communication while designating a communication target device; a second communication unit that performs communication by a broadcasting method that performs signal communication without designating the communication target device; and a switching control unit that, when the first communication unit is performing communication with the communication target device, switches a communication system from the device designation method by the first communication unit to the broadcasting method by the second communication unit in accordance with a communication condition of the first communication unit such that the communication with the communication target device is continuously performed by the second communication unit.

A method performed by a network node for transferring Protocol Data Unit (PDU) sessions of a UE during a mobility procedure in which the UE is moved from a 5GS to an Evolved Packet System (EPS) is disclosed. The method comprises one or more of determining that a target Mobility Management Entity (MME) for the mobility procedure in the EPS supports a first number of EPS Bearers that is less than a second number of EPS Bearer Identities (EBIs) assigned to a number of PDU sessions (e.g., and their associated Quality of Service (QoS) Flows) of the UE that are to be transferred from the 5GS to the EPS; determining which of the PDU sessions and/or QoS Flows of the UE are not to be transferred to the target MME; and releasing, requesting the release of or initiating release of the PDU sessions and/or QoS Flows that are not to be transferred to the target MME.

A method for communication and related devices are provided in the disclosure. The method includes the following. A terminal device determines a failure of access to a target primary secondary cell (PSCell) or a radio link failure (RLF) after the target PSCell is accessed. The terminal device transmits a secondary cell group (SCG) failure report to a first network node, where the SCG failure report includes first indication information, and the first indication information indicates type information of PSCell addition/change.

A multi-tenant computing system provides services to a number of different tenant organizations. To address the problem of failure of portions of the system, the hardware infrastructure of the system is located at a number of different geographical locations. The various tenants are assigned to one of a set of “cells,” each cell corresponding to one of the geographical locations. Additionally, each cell has another one of the cells assigned to it as a backup cell, and the data of each cell is replicated within its assigned backup cell. At system run time, if a failure is detected within one of the cells, the network redirection is used within the multi-tenant system to reflect that the backup cell for the failing cell is now handling requests for the failing cell. Upon determination that the failing cell has been repaired and is now again correctly functioning, the network redirection is no longer employed, such that the (formerly) failing cell again handles its own requests.

Embodiments of the present disclosure relate to a method, a device and a computer-readable medium for guaranteeing communication service. According to embodiments of the present disclosure, a source network device that currently serves the terminal device transmits, to a target network device which will serve the terminal device, information about the amount of resources of network slices utilized by the terminal device. The target network device configures the amount of resources based on the information. In this way, successful handover of the terminal device from the source network device to the target network device is guaranteed, so as to ensure continuity of communication services of the terminal device. In addition, embodiments of the present disclosure creates a network slice in the target network device, which avoids possible interruptions of communication service caused by mapping from the terminal device to the slices supported by the target network device.

A wireless User Equipment (UE) controls a wireless data service that is received from a wireless communication network over a radio band. In the wireless UE, a radio wirelessly exchanges user data with the communication network over the radio band to receive the wireless data service. The radio wirelessly receives a communication performance metric from the wireless communication network over the radio band. The communication performance metric characterizes the wireless data service received by the wireless UE over the radio band. In the wireless UE, user circuitry translates the communication performance metric into a service instruction for the wireless UE over the radio band. The radio wirelessly transfers the service instruction for the wireless UE to the wireless communication network over the radio band. The wireless communication network modifies the wireless data service for the wireless UE responsive to the service instruction.
