An unmanned mobile vehicle M acquires the line quality of a wireless communication line to each of the corresponding base stations having been measured by each mobile station and transmits the line quality to a control station 30. The control station 30 acquires the line quality of a wireless communication line to each of the corresponding mobile stations having been measured by each base station and transmits the line quality to the unmanned mobile vehicle M. When the same communication data is transmitted using two or more wireless communication lines in combination between the control station 30 and the unmanned mobile vehicle M, the transmitting side of the communication data selects two or more wireless communication lines that are used for the transmission of the communication data, on the basis of the line quality of each wireless communication line having been measured by each base station or each mobile station on the receiving side of the communication data

Embodiments of the present application provide methods for checking UE capability match, an AMF, a base station, and a storage medium. The method includes: determining to send a UE capability match request to a base station during a registration procedure initiated by the UE; sending a request for setting up a UE's access stratum (AS) security context to the base station, and sending the UE capability match request to the base station after it is determined that the base station completes setup of the AS security context; receiving a UE capability match acknowledgement returned from the base station. By the method according to the embodiment of the application, the problem that the base station does not respond to the UE capability match process requested by the AMF, which results in that the AMF cannot issue an indication of IMS voice over PS session to the UE during the registration process, can be avoided, and thus the UE can normally obtain IMS voice service.

The present disclosure relates to random access methods and terminal devices. One example method includes determining a first random access time-frequency resource corresponding to a first network slice service, where the first network slice service is a network slice service that is to be initiated, determining a random access type corresponding to the first network slice service, determining a second random access time-frequency resource from the first random access time-frequency resource based on the random access type, where the second random access time-frequency resource is a random access time-frequency resource corresponding to the random access type, and initiating random access based on the second random access time-frequency resource.

Apparatuses and methods in a communication system are provided. A method comprises receiving from network instructions of how to control multi-user multiple input multiple output connections maintained by one or more radio access nodes, the connections utilising one or more slices. One or more radio access nodes perform, based at least in part on the received network instructions, multi-user pairing of terminal devices of the same or different slices, and determine, based at least in part on the received network instructions, slice-based quota taking multi-user pairing and interference arising from paired allocations into account.

Embodiments are directed towards systems and methods for user plane function (UPF) and network slice load balancing within a 5G network. Example embodiments include systems and methods for load balancing based on current UPF load and thresholds that depend on UPF capacity; UPF load balancing using predicted throughput of new UE on the network based on network data analytics; UPF load balancing based on special considerations for low latency traffic; UPF load balancing supporting multiple slices, maintaining several load-thresholds for each UPF and each slice depending on the UPF and network slice capacity; and UPF load balancing using predicted central processing unit (CPU) utilization and/or predicted memory utilization of new UE on the network based on network data analytics.
