Abstract: Communicating commands and/or data to a remote controller, such as a programmable logic controller, coupled to a cellular communications device. Each cellular communications device can monitor the cellular network control channel for a pair of target pages within a first time period. In the event that a cellular communications device receives target pages having a matching specific identifier, the device will monitor the cellular network control channel over a second time period for at least one command page or data page. The cellular communications device can respond to the reception of one or more command or data pages by forwarding instructions or information to the controller via a communications link. In addition, the cellular communications device can acknowledge receipt of the data or command pages by issuing an acknowledgment signal.

Abstract: Embodiments of the invention relate to a mail sending and receiving devices and methods. In one embodiment, a communication device comprises a display unit, and a receiving unit configured to receive a mail which includes a plurality of mail contents and condition information governing which of the plurality of mail contents can be displayed. A storage unit is configured to store the mail which is received by the receiving unit. A control unit is configured to control display of the plurality of mail contents by the display unit in response to the condition information, when a display instruction of the mail which is stored in the storage unit is inputted.

Abstract: A system and method for determining a tariff for a real-time wireless service such as a prepaid service (PPS) for a wireless telephone call. A Local Number Portability Point (LNPP) provides an interface between service scripts in a Service Control Point (SCP) or application server, and an LNP database. When an Initial Detection Point (IDP) message is received by the service scripts, a query is sent through the LNPP to the LNP database to determine whether the call is made to or from a ported telephone number. If so, a routing number is returned. The scripts determine whether the routing number points to the network operator's own network or another, and notify a Service Data Point (SDP). If the routing number points to the operator's own network, the SDP applies a first tariff to the call. If the routing number points to another network, the SDP applies a second tariff.
