Abstract: A method of allowing content-based billing to a prepaid subscriber or subscribers is disclosed. According to one embodiment of the invention, the content-based billing is achieved by forwarding volume limit threshold data normally used by the Serving GPRS support node to the Gateway GPRS support node, which according to the prior art, counted all data bits at the same rate. According to this embodiment, by forwarding the volume limit threshold data to the GGSN, a modified data count is accumulated since billable data is monitored and accumulates, whereas free data does not accumulate. This modified data count is then provided from the gateway GPRS support node to the Serving GPRS support node, which then transmits the accumulated data count to the SCP.

Abstract: A system cools a desired region, such as a walk-in cooler, by taking cool ambient outdoor air and delivering that air into the desired region. The system uses an outdoor temperature sensor so that any time the outdoor temperature falls below a desired degree, the thermostat can turn on fans and open backdraft dampers to bring in cold air. This process by-passes existing coolers, compressors and the like of an existing system, saving the user the high cost associated with conventional walk-in coolers.

Abstract: An improved method and system for accessing wireless data services that reduce messaging and enable roaming subscribers to access data services are described. A wireless communication system in accordance with the present invention includes at least a service control point and a gateway system (e.g., a Gateway Generalized Packet Radio Service Serving Node (GGSN)) that is coupled to a data network. To obtain access to data services, a wireless subscriber unit establishes communication with a gateway system and requests data services from the gateway system. In response to the request, the gateway system queries the service control point regarding authorized data services for the subscriber unit. If the gateway system receives a negative reply from the service control point, then the gateway system denies access to the data services by the subscriber Unit.
