摘要： The interference on the available communication frequencies is measured during an idle time slot over a first period of time at a first rate. The available frequencies are prioritized based on the interference measurements, and a list is formed of the frequencies having the lowest interference measurements. Interference measurements are made at a second rate, greater than the first rate, for a second period of time less than the first period. When a call is assigned, the interference level requirements for the call are given, and the carrier power level of the call is measured. The carrier-to-interference ratio of each frequency in the list is determined using the second interference measurements and the measured carrier power. The frequencies in the list meeting the interference level requirements for the call are then selected, and frequency hopping while serving the call is performed using the selected frequencies.

The intelligent antenna systems includes beams which are grouped into sets, wherein each set has associated a long list and a primary short list, and each beam has associated a secondary short list.

摘要： Operations in a cellular system are controlled based on cost values that are generated using neighbor association. In neighbor association, each cost value corresponds to a cost of assigning a candidate channel to a first cell in the cellular system, assuming that the candidate channel is already assigned to a second cell in the cellular system and each cost value is based on an average power attenuation for all of the cells in the cellular system that share the same tier as the second cell with respect to the first cell, wherein the average power attenuation is based on the reuse distances between the first cell and the cells in the same tier. In one embodiment, the cost values are used in a cost-function-based dynamic channel assignment (DCA) algorithm that is, but does not have to be, applied to a list of candidate channels generated using a measurement-based DCA algorithm.

摘要： An interference based dynamic channel assignment scheme for a wireless communication network, for self configuring dynamic channel assignment of a plurality of channels, comprises the steps of: prioritizing a channel list and prioritizing a selected subset of the prioritized channel list. In further enhancements of the present invention, prioritizing a channel list is distributed on a per cell/sector basis so that prioritization is independent of frequency usage information from other cells/sectors and prioritization is based upon uplink and downlink characteristics.

摘要： In a cellular system, channels are assigned for new calls using a flexible channel allocation algorithm that is a hybrid of a measurement-based dynamic channel assignment (MBDCA) algorithm and a reuse-distance criterion algorithm, such as a cost-function-based DCA (CFBDCA). In one embodiment, the MBDCA algorithm is implemented at each cell site in the cellular system and generates a list of candidate channels for each new call. The list is transmitted to the mobile switching center (MSC), which implements the CFBDCA algorithm to select a particular channel from the list of candidate channels for the new call.

摘要： In a cellular system, channels are assigned for new calls using a cost-function-based dynamic channel assignment (CFBDCA) algorithm. In one embodiment, the CFBDCA algorithm is implemented in the cellular system's mobile switching center (MSC), which maintains a database containing one or more cost tables and a busy channel table. The entries in the cost tables reflect the costs of using a candidate channel in one particular cell of the cellular system, assuming that the channel is already being used in another particular cell. The entries in the busy channel table identify which channels are currently being used in which cells. The CFBDCA algorithm uses the cost tables and the busy channel table to generate cost of reusing the channel (CORC) values. Depending on the implementation, the CFBDCA algorithm of the present invention may or may not be used in conjunction with a measurement-based DCA (MBDCA) algorithm. If so, then the CFBDCA algorithm may be applied to a list of candidate channels generated using the MBDCA algorithm.

摘要： Techniques and systems for planning of wireless networks are described. A system according to an aspect of the present invention receives inputs describing traffic statistics for a wireless network and computes network specifications. The system uses the traffic statistics and network specifications as inputs to a computationally tractable model used to compute parameters for the user level performance of the wireless network. The model may suitably be a processor sharing queuing model. The model employed by the planning system allows analytical solution for the desired user level parameters, given the characteristics and conditions entered as inputs and the intended network layout characteristics. Once a set of user level performance parameters has been computed, the values of the parameters are examined to determine if they meet predetermined requirements, in an iterative process continuing until a set of specifications has been developed that produces parameters meeting the requirements.

摘要： An advantageous scheduling template slot ordering for use in establishing a scheduling order of events such as transmitting communication signals in a communication network is determined by assigning at least two initial slot positions to a particular signal class and then determining a regularity measure based on a lower bound for the regularity measure of such assignments and the remaining unassigned slot positions. This lower bound for the regularity measure of the unassigned slots is advantageously based on a hypothetical assignment of fractions of the slot positions to different signal classes instead of limiting the assignment of a slot to a single signal class. This fractional slot assignment produces a regularity measure that is better than or equal to a corresponding regularity measure based on assigning a whole slot to a particular signal class. The lower bound of the regularity measure is then compared with a threshold regularity measure, such as from a known reference scheduling template. If the threshold regularity measure is lower than the determined lower bound, then it is known that the reference template would provide a more desirable regularity of events than any template having the assigned slot positions to that particular signal class. As a consequence, other slot assignments can be compared to the reference template to rapidly identify scheduling templates with enhanced regularity characteristics.

摘要： A handover method is provided, in which a measure of signal strength is obtained between a user terminal and each of one or more candidate cells, relative to signal strength between the user terminal and a source cell. For candidate cells, a threshold is set that depends on a measure of loading of the source cell and a measure of loading of the candidate cell. For the target cell, a particular candidate cell is identified for which the measure of signal strength exceeds the threshold set for that particular cell. The user terminal is connected to the target cell. In specific embodiments, the threshold for each candidate cell depends on a load differential between the source cell and the candidate cell.
