Techniques for managing the quality of a communication service may include obtaining crowd movement information relating to movement of individuals in a crowd within geographical spaces, and obtaining user activity information relating to one or more activities of interest to a user in a geographical space. A bandwidth density model is generated, based on the obtained crowd movement information and user activity information, the bandwidth model describing a variation of communication bandwidth density in the geographical space with respect to location and time. Quality of communication service parameters are determined, based on the bandwidth density model, with respect to location for the geographical space. Based on the quality of communication service parameters and a current location of the user in the geographical space, a target location in the geographical space is determined for the user. The user is instructed to move to the target location in the geographical space.
