摘要： An exemplary method of managing secure communications between nodes includes receiving a public key of a node associated with a certification authority. A root node certificate is provided to the node responsive to the received public key. The root node certificate indicates that the received public key belongs to the node. A root self-signed certificate corresponding to a public key of the certification authority is also provided to the node.

摘要： A system for managing security keys in a wireless network includes a manufacturer certification authority (MCA) for providing a signed digital MCA certificate for installation into a new network element (NE) at the manufacturer's facility prior to the new NE being installed and initialized in the network. The MCA also provides a source of trusted authority for authenticating legacy NEs in the network. The system includes a service provider certification authority for managing certificates and files used by the NEs to communicate securely within the network, a signing server for providing signing services to NEs for authentication, an element manager for providing security key and digital certificate management, and a management agent (MA) for providing proxy functionality of the EM security key services to NEs not directly connected to the EM.

摘要： It is possible to operate a wireless system, such as a CDMA system, in a more efficient manner by employing a statistical approach for setting power targets for reverse loop transmission. Unlike present methods for setting such targets a figure-of-merit quantity such as the frame error rate need not be measured to set the reverse loop transmission power for a wireless unit. Instead the target is set on a statistical basis established by sampling. Real time measurement of a quantity-of-merit is not required. A statistical approach produces among other things a decreased sensitivity to rapid changes in transmission conditions.

摘要： An algorithm calculates a correction value to be applied to a slot in an adjustment period for power correction. For each slot, the algorithm determines whether adding a correction value in a given slot would bring the actual accumulative adjustment value closer or farther from an accumulative adjustment target value. The accumulative adjustment target value has a linear relationship with the slot number and is calculated for each slot to ensure that any corrections are evenly distributed over the adjustment period for a smooth correction. In one embodiment, the algorithm also checks the total amount of adjustment applied to the slots over a sliding adjustment window to make sure that the total amount of adjustment applied to the slots in the adjustment window do not exceed a predetermined maximum threshold.

摘要： A method and apparatus for estimating the initial power level and transmission rate of a burst on a secondary channel when the secondary channel is on fewer legs of a handoff, such as a soft or softer handoff, than the primary channel. In accordance with the present invention, the initial power level of the burst transmitted over a current secondary channel on a particular leg(s) is a function of a power level of a previous burst transmitted over a previous secondary channel on the identical leg(s) as the current secondary channel. For example, the initial power level of the burst can be based on the power level at the end of the previous burst shortly prior to the termination of the previous burst, where the termination of the previous burst was within a predetermined time interval of the start of the burst. Optionally, the initial power level of a burst can also be additionally adjusted based on characteristics of the communication link of the primary channel, the previous secondary channel, and the current secondary channel. The transmission rate may then be adjusted based on the initial power level determined as described above to obtain a more efficient transmission rate.

摘要： A method and apparatus for detecting discontinued transmission (DTX) frames in data frames received over a link or channel, is described, where a DTX frame is a frame that does not carry data and which is transmitted with zero power over the link or channel. The method and apparatus determines whether a received data frame is a DTX frame based on a plurality of metrics. Based on the metrics, the method and apparatus may effectively discriminate a case where a data frame is received as an erasure (e.g., data frame received with errors), and a case where a transmitted data frame is received as a DTX frame.

摘要： An algorithm calculates a correction value to be applied to a slot in an adjustment period for power correction. The adjustment period is divided into segments having a plurality of slots, and a target power value is determined for each segment. For each slot, the algorithm determines whether adding a correction value in a given slot would bring the actual accumulative adjustment value closer or farther from the target power value for the segment corresponding to the given slot. The correction value is added to consecutive slots in the segment. The algorithm also checks the total amount of adjustment applied to the slots over a sliding adjustment window to make sure that the total amount of adjustment applied to the slots in the window do not exceed a predetermined maximum threshold.

摘要： A reverse link load control strategy utilizes a total call load metric in place of a reverse signal strength indicator metric for managing reverse link resources. In a disclosed example, a load control module (40) measures the reverse signal strength indicator (62) and measures an active cell load (64) using known techniques. A relationship between the reverse signal strength indicator, the active cell load, an other cell load component and a jammer component provides the ability to determine the other cell load component and the jammer component. Once the other cell load component has been determined, a total call load based upon the active cell load component and the other cell load component provides a useful metric for allocating reverse link resources between existing users and for determining whether to allow a new user, for example.
