    摘要: A method of automatically prioritizing cells in a neighbor list of a communications system. The priority is defined as the number of times a cell in the neighbor list has been added to the active set. Cells that have been added to the active set more often are given a higher priority. Such higher priority cells are considered first for addition to the monitored set because they are more likely to successfully move from the monitored set to the active set.

    摘要: A communication system comprises a configuration manager which includes an optimizer for performing a Radio Access Network (RAN) optimization process. An optimization characteristic for the RAN optimization process and operational data for a plurality of remote terminals is determined, and based on this information a grouping processor determines a plurality of groups of remote terminals. A policy processor determines an operational policy for each of the groups in response to the optimization characteristic and the operational data and a policy distributor transmits the operational policy of each group to at least the remote terminals in the group. Each remote terminal then continues to operate in accordance with the operational policy of the group to which the remote terminal belongs. The invention may typically allow improved performance and specifically may allow operation to be adapted to the specific optimization processes being performed. The invention is suitable for a heterogeneous communication system.

    摘要: A technique is used in a spread spectrum communication system (100) such as cdma2000 or UMTS to assign a subscriber unit (120) a link for a supplemental channel, during a handoff period. The technique includes queuing a data packet for transmission to the subscriber unit at a packet transmission time (221) determined by a queue delay (220), obtaining pilot signal strength measurements of at least two active downlinks (125) of the subscriber unit that are measured substantially at the packet transmission time, and determining a strongest one of the at least two active downlinks from the pilot signal strength measurements. The pilot signal strength measurements are obtained by determining a pilot signal measurement time (PSMT) for the subscriber unit, calculating a pilot signal measurement delay (PSMD) from the PSMT and the queue delay, and transmitting a pilot signal measurement request (PSMRQ) to the subscriber unit after the PSMD.

    摘要: A communication system optimizes system performance by selectively managing which mobile stations (MSs) are to serve as test MSs. The test MSs report system operating parameters in order to detect sleeping cells, coverage holes, or other flaws in system coverage or in order to determine an impact of a change in an access network configuration. The communication system further provides for end-to-end messaging between the test MSs and network servers via an access network and a core network, thereby permitting network elements that are best able to perform system optimization to control the monitoring, measuring, and reporting by the MSs. To minimize system and user inconvenience, reporting by a test MS further may be based on one or more of whether the MS is in an area of low mobility, has an acceptable power source output level, and is operating in a cell with an acceptable load level.

    摘要: The invention relates to access management in a radio communication system. A subscriber unit (101) transmits an access message to a base station (103). A Radio Access Controller (RNC) (109) receives information of the access request. The RNC (109) comprises an interference characteristic processor (111) which determines an interference characteristic associated with the subscriber unit (101). The interference characteristic may include an inter-cell interference factor and an intra-cell orthogonality factor determined as a function of the distance between the base station and the subscriber unit and/or based on subscriber unit measurements of pilot signals from the selected base station (103) and neighbouring base stations (105, 107). The interference characteristic processor (111) is coupled to a resource requirement processor (113) which determines a resource requirement for achieving a desired signal to interference ratio for the requested service in response to the interference characteristic. The RNC (109) further comprises an access controller (115) which accepts or rejects the request in response to the determined resource requirement.

    摘要: A method of protecting voice calls in danger of being dropped from a cell of a wireless communication system due to high speed data users. The method including the steps of calculating a signal-to-noise ratio based upon a forward link of each of the plurality of traffic channels within the cell and detecting when the cell is in a overload condition. The method further determines the gain associated with each traffic channels within the cell as well as the channels associated priority level. The method then reduces the gain on the traffic channels with the lowest priority to save the voice call from being disconnected.
