摘要:
A method of generating a handoff candidate list (490) to provide to a mobile station (302) may include providing the mobile station in a multi-sector handoff state (360) with a unique combination of a plurality of sectors (362, 363, 364), and recording at least one target sector (371, 372, 373) selected from a plurality of available sectors (366) that is added to the unique combination of the plurality of sectors. The recording step may be iteratively performed whenever the mobile station is in the multi-sector handoff state with the unique combination of the plurality of sectors thereby defining the at least one target sector that has actually been used by the mobile station in the multi-sector handoff state with the unique combination of the plurality of sectors. Upon the mobile station entering the multi-sector handoff state with the unique combination of the plurality of sectors, providing the handoff candidate list to the mobile station, wherein the handoff candidate list comprises the at least one target sector.
摘要:
A method and system for adaptively allocating shared communication resources in response to an emergency event are disclosed herein. In one embodiment, the method includes identifying a response zone (115) associated with an emergency event and dispatching emergency responders (114, 116, and 118) having communication devices (234a-234m) to the response zone. The dispatching procedure includes adjusting access of the emergency responder communication devices to shared communications resources. Adjusting access to shared communication resources includes identifying one or more of the emergency responder communication devices to be dispatched to the identified response zone and specifying a quality of service (QoS) priority level of at least one of the identified emergency responder communication devices. Adjusting access to shared communication resources further includes specifying a QoS priority level for communication devices located within the identified response zone.

A method and information processing system are provided for dynamically encoding a control channel for transmitting messages to a wireless device based on performance capability information associated with the wireless device. The method includes determining that a wireless device (104) has registered with a base station (116). A device profile (128) associated with the wireless device (116) is retrieved from a register (122). A set of performance capabilities associated with the wireless device is determined (408) in response to the retrieving. A coding type for a control channel for sending messages to the wireless device (104) is determined (410) based on the set of performance capabilities associated with the wireless device (104).
摘要:
A mobile unit 40 which is in a soft handoff condition 50 with a base station (32) has the power transmitted by the base station (32) on the mobile link (52) controlled. The base station (32) determines (70) when a frame erasure count reaches a particular level N. The base station then places this link in a clamped state (72) at minimum power. When the base station determines that M consecutive good frames have been received (92), the base station restores the link (52) to a normal state (94). A recovery arrangement (100, 110 and 120) prevents clamping by all base stations (32-34) and loss of the link.

A power control method (50) is applicable either to a base station 20 or a mobile station (1-N). This method takes into account the previous two power control bits (52-54). The method then determines a correction factor by multiplying the power control step size by the sum of the previous two power control bits (56). A corrected received signal is produced (58) and compared to a threshold signal (62). Based on this comparison, power control is set up (64) for data frames below the signal threshold or power is set down (66) for data frames equal to or above the signal threshold.

This method (110) adaptively sends control messages and a predetermined number of fast repeats of the control messages on the traffic channel of a mobile communication system. For a control message which has already been lost (118), the system sends the control message again with a first number of fast repeats (130) if the traffic channel is operating at a full rate; and the system sends the control message with a second number of fast repeats if the traffic channel is operating at a subrate. The number of fast repeats is selectable. If the control message has not been previously sent and the traffic channel is operating at a subrate (124), the system will send the control message with a third number of fast repeats (128).

摘要:
The present invention provides a method for transmitting a plurality of data packets in a communication network (100). The method includes receiving (404) the plurality of data packets at a packet scheduler. The packet scheduler can be the electronic device (110). The method also includes delaying (406) transmission of a first set of data packets of the plurality of data packets at the packet scheduler. The first set of data packets has a high priority. Further, the method includes transmitting (408) a second set of data packets of the plurality of data packets. The second set of data packets has a low priority. Furthermore, the method includes transmitting (410) the first set of data packets after transmission of the second set of data packets.
摘要:
A CDMA system according to an embodiment of the invention employs a technique for power optimized user loading that obtains a desired allocation of different radio configuration calls. The technique takes advantage of the relatively low power requirements of RC3 calls for low load conditions, while increasing the number of RC4 calls for high load conditions. As the load increases, the percentage of RC4 calls increases while the percentage of RC3 calls decreases. The technique strives to minimize overall power consumption in the system for all call load conditions, by maximizing the number of RC3 calls at any given time while keeping Walsh code resources available for both new calls and hand-in traffic.
