摘要： A mobile station in an idle state is associated with a current sector-carrier that has a current pilot channel at a current carrier frequency. In response to a request to originate a call, the mobile station compares its current sector-carrier with one or more candidate sector-carriers that have pilot channels at carrier frequencies distinct from the current carrier frequency. The mobile station measures received signal strengths of the current carrier frequency and the one or more candidate carrier frequencies and measures pilot signal levels of the current pilot channel and the one or more candidate pilot channels. If a candidate sector-carrier has a carrier frequency with a received signal strength that exceeds that of the current sector-carrier, and has a pilot channel with a pilot signal level that exceeds that of the current sector-carrier, the mobile station uses that candidate sector-carrier to transmit a call origination message.

摘要： A method and system for using data rate as a basis to allow or deny handoff from an IS-856 (e.g., EV-DO) communication system to an IS-2000 (e.g., 1xRTT) communication system. A base station detects that a hybrid terminal has received a threshold low forward link IS-856 data rate for a threshold time period, and the base station will responsively evaluate the IS-2000 system to determine if the IS-2000 system has sufficient resources to provide at least as good a data rate as the IS-856 threshold data rate. If the base station thereby determines that the IS-2000 system is a good alternative, then the base station will allow a handoff to occur when the terminal seeks to handoff to IS-2000. On the other hand, if the base station thereby determines that the IS-2000 system is not a good alternative, then the base station will not allow the handoff to IS-2000.

摘要： A method and system are disclosed for dynamically adjusting forward-link transmission power in a cellular wireless communication system. A base station controller (BSC) or other radio network entity determines that a given cell sector a given sector is serving at least one active mobile station while no other sector in a cluster of sectors associated with the given sector is also serving at least one active mobile station. In response, the BSC dynamically increases the pilot transmit power in the given sector to a level beyond the sector's normal (full) transmit power, in an effort to increase requested data transmission speed in the sector.

摘要： A method and system are disclosed for reducing pilot pollution in a wireless communication system by systematically (i) identifying areas of sector overlap and (ii) for each area, adjusting power allocation in one or more of the overlapping sectors so as to create a dominant sector and to reduce the total noise from other sectors. A preferred embodiment of the invention involves collecting RF performance data, filtering the data to focus on areas having threshold low forward link data rate, further filtering the data to focus on areas in which the low forward link data rate is likely the result of pilot pollution, selecting a geographic region in which to make a sector power adjustment, and making a sector power adjustment in the selected region in an effort to reduce pilot pollution and increase forward link data rate. The invention is particularly advantageous in a hybrid EV-DO/1xRTT system.

摘要： A method and system are disclosed for dynamically adjusting forward-link transmission power in a cellular wireless communication system. A base station controller (BSC) or other radio network entity determines that a given cell sector is transmitting data to at least one mobile station and that no cell sector in a cluster associated with the given cell sector (e.g., among neighboring sectors) is also transmitting data to at least one mobile station. In response, the BSC dynamically increases the forward-link transmit power in the given sector to a level beyond the sector's normal (full) transmit power. The invention preferably applies on a per-timeslot basis and the power increase occurs in at least a data channel segment, to help increase data transmission speed.

摘要： A method and system for using data rate as a basis to allow or deny handoff from a communication system operating under a first air interface protocol (first protocol system) to a communication system operating under a second air interface protocol (second protocol system). A base station detects that a hybrid terminal has received a threshold low forward link data rate under the first protocol for a threshold time period, and the base station responsively evaluates the second protocol system to determine if the second protocol system has sufficient resources to provide at least as good a data rate as the threshold data rate. If the base station thereby determines that the second protocol system is a good alternative, then the base station will allow a handoff to occur when the terminal seeks to handoff to the second protocol. Otherwise, the base station will not allow the handoff to occur.

摘要： A mobile station is associated with a first wireless coverage area that has a first pilot signal. A second wireless coverage area that has a second pilot signal is in the mobile station's neighbor list. The mobile station measures E1, the energy per chip of the first pilot signal, and I1, the total received power at the first pilot's frequency. The mobile station also measures E2, the energy per chip of the second pilot signal, and I2, the total received power at the second pilot's frequency. If E2 exceeds E1 by at least a first predetermined amount and E2/I2 exceeds E1/I1 by at least a second predetermined amount, then a handoff of the mobile station from the first wireless coverage area to the second wireless coverage area is effected.

摘要： A network access server, such as a PDSN, might provide Mobile IP services to one or more access points for a wireless wide area network. A wireless device might handoff to an access point served by the network access server, and the wireless device might receive from the access point an identifier, such as a Packet Zone ID, that identifies the network access server. The wireless device might then register with the access server but delay making any subsequent Mobile IP re-registrations until after a predetermined amount of time.
