    摘要: The method provides for establishing a communication session in a hierarchical communication system between a source party and at least one destination party. Hierarchical communication systems generally have communication nodes at different levels of hierarchy. In one embodiment, connection information for the communication session is stored if establishing the communication session is blocked at a node as a result of a blocking condition at the blocking node. Establishment of the communication session is initiated based on the stored connection information if the blocking condition no longer exists at the blocking node.

    摘要: A wireless communication system (20) allows communications between a mobile station (22) and a wireless network (24) over combined physical traffic channels (44, 46). In a disclosed example, a mobile station (22) has multiple wireless access terminals (40, 42) for transmitting different portions of a communication over multiple physical traffic channels (44, 46). In a disclosed example, each wireless access terminal (40, 42) utilizes one of the channels (44, 46). A known multilink PPP protocol facilitates splitting a communication into portions to be communicated over the combined physical traffic channels (44, 46) and then recombined at the mobile station (22) or an appropriate portion of the network (24). With a disclosed example, the achievable throughput using combined physical traffic channels (44, 46) approaches the aggregate or sum of the individual channel throughput capacities.

    摘要: Separate power control for the forward voice channel and forward data channel is provided without using additional bandwidth or decreasing the amount of pilot signal provided from the mobile to the base station. Alternating voice and data power control commands or information are transmitted in the pilot channel by a mobile to a base station. In one embodiment, the power control portion of a first pilot channel segment is used to provide power control for the forward voice channel and then in the following pilot channel segment, the power control portion is used to provide power control for the forward data channel. In other embodiments, other than a 50/50 mix between voice and data power control is provided in the mobile's pilot channel. For example, forward voice channel power control commands may be transmitted two or more times for each transmission of forward data channel power control commands.

    摘要: A technique for de-assigning signals from the fingers of a rake receiver is disclosed. In general, embodiments of the present invention place more stringent standards on signals that have been newly assigned to a finger and may be spurious and place less stringent standards on mature signals that have proved themselves over time but may be experiencing only a temporary signal quality shortfall. Illustrative embodiments of the present invention accomplish this goal using one or more of four techniques. The first technique de-assigns a signal from a finger when a measure of signal quality of the signal crosses a threshold, while changing the threshold as a function of the duration that the signal has been assigned to the finger.

    摘要: The invention is a repeater for a telecommunications transmission system such as a CDMA wireless system. The repeater reduces leakage by using a feedback signal whose amplitude and phase are adjusted in response to the amplitude and phase of a sampled input signal when a switch turns off the normal output of the repeater for a short period of time. In one embodiment, a pilot signal is transmitted during this time period so that the sampled input is the leakage signal. In another embodiment, the sampled input is the normal transmission signal received during the time period.
