Abstract: A system for transmitting data through an IP core network so that data may be transmitted from an originating source, through a public switched telephone network (PSTN) and through the IP core network to a land line telephone and a cellular telephone. The system includes an IP core network that is coupled to the PSTN through an interface. The IP core network is also coupled to an access IP network. A radio access network is coupled to the IP core network and the cellular telephone. Upon receipt of data from the originating source, the IP core network simultaneously initiates a ringing of the land line telephone through the access IP network and a paging of the cellular telephone through the radio access network.

Abstract: A wireless communication system (10) uses communications bridging functions to establish redundant communication paths (32, 34, 44, 46) between redundant radio access network session clients (36, 38), a core system 16 and a base transceiver station (40). The system (10) carries out a handoff or reallocation of call control from one of the radio access network session clients (36, 38) to another one of the radio access network session clients (36, 38) based on the integrity of the redundant communication paths (32, 34, 44, 46).

Abstract: A method including the steps of receiving a mobile identification number identifying a mobile unit (36), performing a multilateration location measurement based on a nonperiodic signal received from the mobile unit (116), retrieving a location zone from a memory based on the mobile identification number (210), comparing the multilateration location measurement with the location zone, and generating a billing record for the mobile unit (214).

Abstract: The present invention provides a communication system (100) and a method for determining when a communication unit (105) is located within a preferred zone in the cellular communication system (100). The cellular communication system (100) includes a plurality of cells. A preferred zone for a communication unit (100) is created. Radio characteristics associated with the preferred zone, such as pilot signal, cell ID, and distance, are obtained. It is then determined, based at least in part upon the radio characteristics, when the communication unit (100) is located within the preferred zone.

Abstract: A meter data collection device (20) including an antenna (52), a meter interface (60) receiving data from a meter (64), and a radio frequency (RF) stage (50). The RF stage (50) is coupled to the antenna (52) and is responsive to the meter interface (60). The RF stage (50) is operable for transmitting the meter data over a control channel of a wireless communication system.
