    Abstract: A method of detecting DTX frames in frames received over a communication channel and power control method are described, where radio link protocol (RLP) information received over the channel may is received, and one or more frames associated with the RLP information may be determined as an erasure or a DTX frame, based on said RLP information. Such determination may be incorporated into outer loop power control algorithms for adjusting a threshold related to a specified quality of service.

    Abstract: A method/apparatus identifies other cell interference in a wireless network and determines whether a handoff to an affected base station should occur. In one implementation, a base station of a CDMA-based wireless network continuously monitors reverse link interference levels to detect an increased interference condition, and initiates a CDMA mobile identifying sequence to determine whether the interfering signal source is a proximate mobile being served by a neighboring base station of the network. The affected base station obtains a list of long code masks for mobiles being served by neighboring base stations, and instructs at least one receiver unit to sequentially despread received signals using each of the listed long code masks. When the receiver unit detects a signal transmitted by a non-served mobile, the base station analyzes relative reverse link signal strength for the non-served mobile, e.g., using Ec/Io measurements, to determine whether the non-served mobile is likely be the source of interference. Having determined that a nearby CDMA mobile is the source of interference, the affected base station may initiate one of a number of possible actions, including triggering a handoff to the affected base station so that the affected base station could control the transmit power level of the mobile, requesting that the interfering mobile be switched to a different frequency carrier or dropped, or merely recording the interference condition.

    Abstract: A method and apparatus estimate the initial power level and transmission rate of a burst on a secondary channel (182) when the secondary channel (182) is on fewer legs (132) of a handoff, such as a soft or softer handoff, than the primary channel (162, 164, 166). In accordance with the present invention, the initial power level of the burst transmitted over a current secondary channel (182) 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) (132) as the current secondary channel (182). 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 (162), the previous secondary channel, and the current secondary channel (182). The transmission rate may then be adjusted based on the initial power level determined as described above to obtain a more efficient transmission rate.

    Abstract: 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.
