摘要： A system and method for improving soft hand-off in a CDMA system uses mobile station location and velocity information to maintain soft hand-off legs with those cells in which the mobile station is more likely to be located. The system and method of the present invention estimates the weighted probability of the mobile station arriving in neighboring cells and produces “bias” values for those cells that the mobile station is more likely to be entering or to be located in. These bias values are used for modifying signal quality values for those cells, and for determining whether the current cell or neighbor cells are to be placed in an active set so as to establish, or maintain, soft hand-off legs. The system and method of the present invention thus chooses those cells which are more likely to be retained as soft hand-off legs and therefore reduces the overall number of soft hand-offs.

摘要： A technique is disclosed for traffic management in spread spectrum wireless telecommunications systems using different admission control levels different frequency layers. In an embodiment of the invention, the capacity on a first frequency, having a specific admission control level, is permitted to increase to the point where the development of coverage holes occurs due to the effects of cell breathing are present. This is compensated for by maintaining a designated frequency that is free from coverage problems by applying a stricter admission control relative to the first frequency. Thus calls or new access attempts affected by coverage problems on the first frequency are diverted to the designated frequency. The method improves overall network capacity and call quality in the network by more efficiently utilizing spectral resources.

摘要： Radiocommunication systems having improved soft handoff capabilities are described. During soft handoff a mobile station may have several transmission sources (active set members) supplying it with substantially the same information. Mobile stations which are not moving may not require as many sources to provide adequate received signal quality. Therefore, mobile stations which are not moving are identified using locating techniques and members of the active set are compared with a higher threshold to remove weaker branches more rapidly than when using a threshold that is applied to mobile stations that are in motion.

摘要： The downlink transmit powers of base stations involved in a diversity handover communication with a mobile station are controlled to minimize base station power “drift.” A downlink reference power level is determined based on detected, current transmit power levels of the diversity handover base stations. One or more power offsets is determined for one or more of the base stations based on signal quality measurements made by the mobile station. The reference power level and power offset(s) are used to selectively regulate an adjustment to the transmit power levels of the diversity handover base stations. The general reference power is transmitted at a first, relatively high frequency to the diversity handover base stations by embedding it in a user data frame. In that way, the signal processing load is kept to a minimum despite the higher transmission rate. Individual power offsets are sent to associated individual base stations in a control signalling channel identifying the one base station at a second frequency lower than the first frequency. The control channel signaling permits individual base station power offsets, but the lower frequency at which the offsets are transmitted reduces the associated signaling load.

摘要： An adaptive handoff algorithm that governs mobile handoffs between sectors within base stations in a CDMA system is disclosed. The handoff algorithm is selected according to the type of service requested by the mobile. Further, the handoff algorithm uses various quality measures in order to induce mobile handoffs that result in desirable operating conditions for the type of service requested by the mobile. For example, a voice call may result in an handoff algorithm that induces the mobile to handoff to sectors that minimizes the mobile output power in order to maximize battery capacity and decrease uplink interference. Moreover, another algorithm may be implemented for packet intensive services, such as internet web browsing, to induce the mobile to handoff to sectors that result in reduced downlink output power, which tends to decrease interference in the cell.
摘要翻译：公开了一种控制CDMA系统中基站内扇区之间移动切换的自适应切换算法。根据移动台请求的业务类型来选择切换算法。此外，切换算法使用各种质量度量来诱导针对移动台请求的服务类型导致期望的操作条件的移动切换。例如，语音呼叫可能导致切换算法，其导致移动台切换到最小化移动输出功率的扇区，以便最大化电池容量并减少上行链路干扰。此外，可以针对诸如互联网浏览的分组密集型服务实现另一种算法，以诱导移动台切换到导致减少的下行链路输出功率的扇区，这倾向于降低小区中的干扰。

摘要： A technique for regulating the transmit power level for a mobile station following a hard handoff in a code division multiple access (CDMA) based system is disclosed. In an embodiment of the invention, a profile is developed from data associated with transmit power levels from a statistical collection of a plurality of hard handoff events. A power margin is derived from the profile such that it may be varied in accordance with high or low load conditions in the system. The power margin is then applied to mobiles performing hard handoffs such that they transmit only at the appropriate power level required for a sufficient connection in the cell. The technique provides an automated and dynamic power margin which is scalable according to the varying loading conditions in the system. The invention reduces the amount of interference generated by transmitting at unnecessarily high power levels following hard handoffs thereby improving the overall performance and connection quality of the system.

摘要： Embodiments herein relate to a method in a radio base station (12) for scheduling a radio resource to a first user equipment (10). The radio base station (12) is comprised in a radio communications network and controls a number of radio resources to be scheduled for communication to a number of user equipments (10,11). The number of user equipments comprises the first user equipment (10) and being served by the radio base station (12). The scheduling is based on channel quality of channels used by the respective user equipments. The radio base station (12) estimates a first channel quality of a channel used by the first user equipment (10). The radio base station determines a pathloss between the first user equipment (10) and the radio base station (12), and computes a second channel quality of the channel based on the estimated first channel quality and the determined pathloss. The radio base station (12) then schedules a radio resource out of the number of radio resources to the first user equipment (10) based on the second channel quality.

摘要： A radio access network (20) comprises a radio network controller (26) and a radio base station (28). The radio network controller (26) is configured to perform admission control and to allocate resources of a cell. The radio base station (28) is configured to determine load/congestion on a high speed shared channel and to generate an indication of the load/congestion for transmission to the radio network controller. In some example embodiments and modes, at least one of the radio network controller and the radio base station is configured to allocate at least some of the resources for the high speed shared channel to support a guaranteed service and also to allocate at least some resources to support a non-guaranteed service. In some example implementations of this aspect, a user(s) of the non-guaranteed service is permitted to use the resources up to a reserved resource level of resources. According to another non-limiting aspect of the technology, the radio base station is further configured to generate a recommended action for dealing with the load/congestion.
