摘要： An intelligent real estate system including an intelligent real estate sign having embedded processing functionality and a wireless communication device capable of receiving wireless electronic queries and programming instructions and for communicating with local and remote information sources about a real estate property and with controlling agents for reporting status. Further included is an electronic lock box controlling access to the real estate property and having an embedded wireless communication device capable of receiving messages and control signals from the real estate sign and from a property owner/occupant and/or real estate agents for reporting status. An earth battery may also be included, at least partially contained within the real estate sign and supplying power to the real estate sign.

摘要： A cellular radio communications system comprises: at least one base station for broadcasting radio signals to mobile stations within a cell; a mobile station addressable using IP addresses; and a first controller in the cell of the cellular radio communications system, the first controller being adapted: (i) to receive a request from the mobile station that the cellular radio communication system assign to the mobile station the static IP address previously assigned to the mobile station outside of the cell; (ii) in response to the request from the mobile station, to check with a second controller associated with the location where the mobile station was previously registered that the static IP address has not been assigned to another mobile station; and (iii) to assign the static IP address previously assigned to the mobile station, outside of the cell, to the mobile station for use in the cell, if the static IP address has not been assigned to another mobile station. Alternatively, the first controller may perform the check for availability of the static IP address with a controller associated with the location where the static IP address is registered. The invention also comprises methods of mobile station registration in cellular radio communication systems. The invention enables roaming by a mobile station between cellular systems which are under the control of different Software and Measurement Infrastructures. Mobile stations may be adapted to check one or more timers prior to making the static IP address request.
