Abstract: An apparatus, system, and method efficiently manage reverse link communication in a communication system having geographically distributed base stations. Coupled load information is exchanged between base stations allowing a base station to determine an appropriate allocation of reverse link channel resources to mobile stations served by the base station. Since the allocation of reverse link channels resources are controlled directly by the base station, delays due to communications with a central controller are eliminated. As a result, adverse effects of load scheduling based on obsolete reverse channel information are minimized.

Abstract: For calls involving a wireless device on a wireless wide area network, a network entity may create an electronic record for the call that includes an indication of whether the call was established with vocoder bypass. A service provider of the wireless wide area network may then use the indications in the electronic records, at least in part, as a basis for billing a user of the wireless device. The service provider may additionally use the electronic records to generate statistics about the usage of the wireless wide area network.

The time indicator and at least one of the position information and the location are used to establish a time at the first basestation such that the first basestation is synchronized to other basestations in the cellular communication system. Other methods and apparatuses are also described for synchronizing basestations in a cellular network.

Abstract: An apparatus, system, and method efficiently manage reverse link communication in a communication system having geographically distributed base stations. A base station functioning to at least one mobile station as a non-serving active base station estimates an expected coupled load due to the at least one mobile based on a previous total coupled load. The base station determines a total available capacity based on the difference between the total capacity of the base station and the estimated expected coupled load. The base station allocates reverse link resources to other mobile stations served by the base station so as not to exceed the total available capacity. Since the allocation of reverse link channels resources are controlled directly by the base station, delays due to communications with a central controller are eliminated. As a result, adverse effects of load scheduling based on obsolete reverse channel information are minimized.

Abstract: A handoff system and method using an MPTY (multiparty) service in a mobile communication system. When a terminal senses that it is located at the boundary of a WCDMA during a WCDMA communication service, it transitions to a first state. In the first state, the terminal requests an MPTY service to a BS in a CDMA network. If the strength of a first current WCDMA signal is less than a predetermined first threshold, the terminal transitions to a second state. In the second state, the terminal requests an available MPTY call to be maintained. If the strength of a second current WCDMA signal is less than a predetermined second threshold, the terminal transitions to a third state. Then the terminal establishes a CDMA call using the maintained MPTY call in the third state. If the strength of a third current WCDMA signal is less than a predetermined third threshold, the terminal ends the WCDAM call.

Abstract: A count is made of the number of mobile assisted handoff (MAHO) attempts between a service cell and a targeted cell. A count is also made of the number of times the targeted cell is considered a Best Candidate (BestCand) for handoff from the service cell. If the targeted cell is not included in the service cell's neighbor list, a potential neighbor cell (PNC), hysteresis is added to the targeted cell to prevent handoffs to the targeted cell. The MAHO and BestCand counts are determined and if the counts meet or exceed predetermined threshold values the targeted cell is added to the list. If the targeted cell is on the neighbor list, no hysteresis is added.

Abstract: A cellular phone unit, upon turning from a standby mode to a data communication mode, responds to a user's instruction of location positioning to turn from the data communication mode to the dormant mode, receives again base station identification numbers from several base stations through a paging channel, and designates again one of the base stations with the received identification numbers as the base station of primary communication with the phone unit. The phone unit can send the identification number of the proper base station of primary communication to a location information server even in case the phone unit is instructed by the user to commence the location positioning after it has moved from the location where it had commenced the data communication.

Abstract: A method for finding the position of a subscriber in a radio communications system combines transmission signals from subscribers to form a transmission sum signal, which is passed by cables from a base station to at least two antenna devices for transmission. Received signals from subscribers are received via the antenna devices and are combined to form a received sum signal, which is passed by cables to the base station. Each individual antenna device is associated with an individual area for the radio supply for the subscribers there. Cables lengths, which are used for signal transmission, for each antenna device are chosen individually such that a round trip delay time measurement which is based on the transmission signal and received signal of a sought subscriber is used to determine an antenna device via which the received signal sought subscriber is received. The position of the sought subscriber is determined via the area which is supplied by radio and is associated with the determined antenna device.

Abstract: Agile frequency converter and method, IF-RF level exchange process, and notch filtering techniques. System noise and spurious levels generated by channel frequency conversion is reduced in applications requiring broadband combining of frequency converters to form multichannel composite signal. Converter employs two-stage frequency conversion process, with gain exchange system using variable pre-mixer gain and variable post-mixer attenuation to maintain constant RF output signal power level. For those few conversion frequencies where distortion component(s) cannot be filtered without degrading desired signal, IF-RF level exchange is optimized for meeting the carrier-to-distortion (C/D) ratio specifications at slight expense of noise level for that channel only, while still meeting aggregate combined carrier-to-noise (C/N) specification requirements.
