1. A communications device for use in a wireless communications system comprising an infrastructure equipment, a location server and the communications device, the communications device comprising:
transceiver circuitry; and
controller circuitry configured in combination with the transceiver circuitry to:
request, using a first wireless communications technology and in a case that the communications device determines that a first communication trigger is satisfied, assistance information from the location server via the infrastructure equipment, wherein the first communication trigger is satisfied when the communications device has moved from outside of a building to a position inside the building;
receive the assistance information from the location server via the infrastructure equipment and in response to the request, wherein the assistance information includes a second communication trigger which is triggered with movement to a position within a first area inside the building, the first area including a point of interest (POI);
pre-emptively download and locally store in the communications device, in a case that the communications device determines the second communication trigger is satisfied, guide content relating to the POI;
receive, in a case that the communications device has moved to a position within a second area and closer to the POI, a beacon identifier via a second wireless communications technology from a device in a proximity of the POI in the second area without communication via the infrastructure equipment, wherein the second area is within the first area and the POI is in the second area;
estimate, based on the beacon identifier received from the device, a position of the communications device with respect to the POI;
determine whether a third communication trigger has been satisfied based on the position;
select, in a case that the communications device determines that the third communication trigger has been satisfied, a wireless communications technology to be used for communication while the communications device is in the proximity of the POI; and
output, in the case that the communications device determines that the third communication trigger has been satisfied, the guide content locally stored in the communications device.
