A simulation of mobile information services

In the case of the limited bandwidth of location based services (LBS), how to provide high-quality and high-efficiency geographic information service to users is the task we will face. A location based service (LBS) system's simulation has been implemented in this article, and a service mode of push technique combined with adaptation method is used for the system's simulation. In the meanwhile, tor saving channel resource, this paper uses all information update scheme with minimal update frequency based on the customer's current state only when the service is requested, providing that Qos is satisfied. It shows that the system we have simulated can give users navigation instructions, including some users' special requests.
