receiving visual data captured by the camera of the UE; performing a computer vision operation, trained on the stored visual data, on the captured visual data to determine that the visual representation of the base station or part thereof is present in the captured visual data; and, initiating a transfer of the UE to the base station. ## Claims ### Claim 1 A method of initiating a transfer in a cellular telecommunications network, wherein the cellular telecommunications network comprises a User Equipment (UE) and a base station, wherein the UE includes a camera, the method comprising: storing visual data including a visual representation of at least a part of the base station; receiving visual data captured by the camera of the UE; performing a computer vision operation, trained on the stored visual data, on the captured visual data to determine that the visual representation of at least a part of the base station is present in the captured visual data; and, in response, initiating a transfer of the UE to the base station. ### Claim 2 (depends on 1) The method as claimed in claim 1, wherein the base station has a first mode and a second mode and uses more energy when operating in the first mode than the second mode, and wherein the base station is initially in the second mode, and initiating the transfer of the UE includes initiating a switch in the base station from the second mode to the first mode. ### Claim 3 (depends on 2) The method as claimed in claim 2, wherein the base station is a target base station and the UE is served, prior to the transfer, by a serving base station having the first mode and the second mode, and the method further comprises initiating a switch in the serving base station from the first mode to the second mode. ### Claim 4 (depends on 3) The method as claimed in claim 3, wherein the stored visual data includes a first visual representation of at least a part of a serving base station and a second visual representation of at least a part of a target base station, and the method further comprises: processing a sequence of visual data captured by the camera of the UE to: determine that the second visual representation of at least a part of the target base station is present in the captured visual data, and determine that relative motion between an object, the UE and the serving base station is such that there is a probability above a threshold that the object will block a line of sight between the UE and the serving base station; and, in response, transferring the UE is transferring the UE from the serving base station to the target base station. ### Claim 5 (depends on 1) The method as claimed in claim 1, wherein the method is implemented in one or more of the UE, the base station, and a network node. ### Claim 6 (depends on 1) The method as claimed in claim 1, wherein the visual representation of at least part of the base station further includes one or more distinctive features in surroundings of the base station. ### Claim 7 (depends on 1) A computer program product comprising instructions which, when the program is executed by a respective processor provided in one or more of the, the base station, and a computer network node, cause the one or more of the UE, the base station and/or the computer network node to carry out the method of claim 1. ### Claim 8 (depends on 7) A computer-readable data carrier having stored thereon the computer program of claim 7. ### Claim 9 (depends on 7) A network node in a cellular telecommunications network, the network node comprising a transceiver, a processor and a memory storing the computer program of claim 7. ### Claim 10 (depends on 9) The network node as claimed in claim 9, wherein the network node is either the UE or the base station.
