A method for cell reselection performed by a terminal includes: receiving, by the terminal, priority information relating to a tracking area (TA); and on the basis of the priority information, implementing, by the terminal, cell reselection. A method for information transmission, including: issuing, by a base station, priority information relating to a TA, wherein the priority information is configured for cell reselection of a terminal.

A method is disclosed for a coprocessor of a device. The coprocessor may initiate, based on an instruction received from a processor, a wireless communication service required by the processor. The coprocessor further generates a drive instruction for driving a wireless communications module of the device to perform the wireless communication service, and then the coprocessor sends the drive instruction to the wireless communications module.

A method and apparatus for acquiring a Radio Access Technology (RAT) of a serving cell, a method and apparatus for indicating a RAT of a serving cell, and devices are provided. The method for acquiring a RAT of a serving cell includes: receiving RAT indication information from the relay device, wherein the RAT indication information indicates RAT information of the serving cell where the relay device is located; determining, based on the RAT indication information, a RAT type adopted by a base station to which the serving cell belongs; and communicating with the base station using the RAT appropriate to the RAT type adopted by the base station.

Network Slice Selection Assistance information (NSSA1) may be signaled between U ser Equipment (UE) and a network. NSSA1 sent from the network to the UE may include, for example. Operating Frequency Band (OFB) for each Single NSSAI(S-NSSA1) in the NSSAI, as well as a Radio Access Technology (RAT) Frequency Selection Priority (RFSP) index, which the network configures as a part of UE access and mobility; subscription, during a UE registration procedure. RAT restrictions may be enhanced to indicate to the UE that certain slices are not accessible via certain RATs. A UE may be provided by the network with an alternative NSSAI and corresponding OFBs for each S-NSSAI thereby indicating to the UE that these S-NSSAI would have been allowed had they been requested. A UE may be able to choose an alternative Allowed NSSAI and send a registration update request to the network.

A method for dispatching radio coverage drones to a geographical area of a failing node in a radio network, wherein the radio coverages drones are configured to re-establish operability of the failing node is disclosed. The method comprises steps being performed by a network node of generating (102) a radio coverage map, wherein the generated radio coverage map covers the geographical area of the failing node and geographical areas of adjacent nodes, identifies at least one mobile communication device having radio coverage from at least one of the adjacent nodes, and defines a size of the geographical area of the failing node, dynamically calibrating (103) the defined size of the geographical area of the failing node of the dynamically generated radio coverage map by: calculating (103a) a first distance between the identified mobile communication device and a selected one of the adjacent nodes, wherein the identified mobile communication device has coverage from the selected adjacent node while being geographically closer to the failing node than to the selected adjacent node, deducing (103b) a second distance between the failing node and the selected adjacent node, determining (103d) the actual size of the geographical area of the failing node based on the second and the first distance, and determining (104) a number of radio coverage drones to be dispatched to the geographical area of the failing node, wherein the number of radio coverage drones is based on to the actual size of the geographical area of the failing node. Corresponding computer program product, arrangement, network node, and system are also disclosed.
