if the moving speed is higher than or equal to a speed threshold, allowing the mobile terminal to use a current dedicated network; and if the moving speed is lower than the speed threshold, refusing the mobile terminal to use the current dedicated network. ## Claims ### Claim 1 A method for controlling a mobile terminal to use a network, applying to a base station, the method comprising: receiving a moving speed reported by the mobile terminal; and when the moving speed is higher than or equal to a speed threshold, allowing the mobile terminal to use a current dedicated network; or when the moving speed is lower than the speed threshold, refusing the mobile terminal to use the current dedicated network. ### Claim 2 (depends on 1) The method of claim 1, wherein when the reported moving speed is carried in a third message in a random access procedure, allowing the mobile terminal to use the current dedicated network comprises: permitting the mobile terminal to access the current dedicated network through a fourth message in the random access procedure. ### Claim 3 (depends on 1) The method of claim 1, wherein when the moving speed is carried in a fifth message in a random access procedure, allowing the mobile terminal to use the current dedicated network comprises: allowing the mobile terminal to continue to use the current dedicated network. ### Claim 4 (depends on 1) The method of claim 1, wherein when the moving speed is carried in a third message in a random access procedure, refusing the mobile terminal to use the current dedicated network comprises: refusing the mobile terminal to access the current dedicated network through a fourth message in the random access procedure. ### Claim 5 (depends on 1) The method of claim 1, wherein when the reported moving speed is carried in a fifth message in a random access procedure, refusing the mobile terminal to use the current dedicated network comprises: releasing a connection with the mobile terminal through radio resource control (RRC) connection release signaling; or notifying the mobile terminal of accessible public network information through the RRC connection release signaling. ### Claim 6 A method for reporting information, applying to a mobile terminal, the method comprising: determining that the mobile terminal needs to access a current dedicated network; and reporting a moving speed of the mobile terminal to a base station of the current dedicated network, such that the base station allows or refuses the mobile terminal to use the current dedicated network. ### Claim 7 (depends on 6) The method of claim 6, wherein the method further comprises: determining the moving speed of the mobile terminal before reporting the moving speed of the mobile terminal to the base station of the current dedicated network. ### Claim 8 (depends on 6) The method of claim 6, wherein reporting the moving speed of the mobile terminal to the base station of the current dedicated network comprises: reporting the moving speed to the base station of the current dedicated network through a third message in a random access procedure or a fifth message in the random access procedure. ### Claim 9 A base station, comprising: a processor; and a memory device configured to store instructions executable by the processor, wherein the processor is configured to: receive a moving speed reported by the mobile terminal; allow the mobile terminal to use the current dedicated network when the moving speed is higher than or equal to a speed threshold; and refuse the mobile terminal to use the current dedicated network when the moving speed is lower than the speed threshold. ### Claim 10 (depends on 9) The base station of claim 9, wherein when the moving speed is carried in a third message in a random access procedure, the processor is further configured to: permit the mobile terminal to access the current dedicated network through a fourth message in the random access procedure. ### Claim 11 (depends on 9) The base station of claim 9, wherein when the moving speed is carried in a fifth message in a random access procedure, the processor is further configured to: allow the mobile terminal to continue to use the current dedicated network. ### Claim 12 (depends on 9) The base station of claim 9, wherein when the moving speed is carried in a third message in a random access procedure, the processor is further configured to: refuse the mobile terminal to access the current dedicated network through a fourth message in the random access procedure. ### Claim 13 (depends on 9) The base station of claim 9, wherein when the moving speed is carried in a fifth message in a random access procedure, the processor is further configured to: release a connection with the mobile terminal through radio resource control (RRC) connection release signaling; or notify the mobile terminal of accessible public network information through the RRC connection release signaling. ### Claim 14 (depends on 6) A mobile terminal, comprising: a processor; and a memory device storing instructions for execution by the processor to implement steps of the method for reporting information according to claim 6. ### Claim at position 15 -20. (canceled) ### Claim 21 (depends on 1) The method of claim 1, wherein the speed threshold is configured by an Operation Administration and Maintenance (OAM) system. ### Claim 22 (depends on 9) The base station of claim 9, wherein the speed threshold is configured by an Operation Administration and Maintenance (OAM) system. ### Claim 23 (depends on 1) A communication system implementing the method of claim 1, comprising the base station, wherein the network is a dedicated network for mobile terminals moving faster than the speed threshold. ### Claim 24 (depends on 23) The communication system of claim 23, wherein the dedicated network is configured to determine, based on a comparison result, whether the mobile terminal is a high-speed-moving mobile terminal or a general mobile terminal in an initial access phase of the mobile terminal, such that the mobile terminal accessing the dedicated network is managed to avoid communication quality of the high-speed-moving mobile terminal being affected due to that the general mobile terminal attempts to access the dedicated network. ### Claim 25 (depends on 24) The communication system of claim 24, wherein the dedicated network is a high-speed-railway dedicated network. ### Claim 26 (depends on 25) The communication system of claim 25, further comprising a plurality of mobile terminals moving faster than the speed threshold.
