Abstract: The present invention addresses the need for a device and method of frame reconstruction among soft handoff legs that improves the reliability of received information without reducing RF capacity. Given received frames from each leg of a soft handoff (300-303) a reconstructed frame (304) is produced. Subframes (e.g., 362) with passing inner frame quality indicators (352) are selected for the reconstructed frame. For portions of the reconstructed frame (e.g., 324 and 344) that do not have corresponding portions in the leg frames with passing inner frame quality indicators, a bit-wise majority rule is applied to select values.

Abstract: To address the need for reducing wireless data transfer delay, an embodiment of this invention provides for a radio access network (RAN) ( 110 ) to transmit data, such as a data query, at the time of paging a dormant wireless unit ( 101 ). By transmitting the data at this time, wireless unit activity in response to the data can begin while the paging and traffic channel setup proceed. Thus, once established, the traffic channel will be idle for less time than under the present practice were data is not sent until the traffic channel setup is completed. Less idle traffic channel time is expected to improve channel utilization and contribute to lower packet data costs.

Abstract: A communication system and method assigns, such as by marking headers of wireless communication packets, packet classification data to packets to define at least one of the following classes: a control signaling class, such as in-band signaling and control packets, a voice class, a data retransmission class, OAMP class and a data class and wherein each class represents a different transmission priority over a backhaul link. For wireless communication packets associated with the control signaling class and the voice class, the method and apparatus assigns each of the wireless communication packets with additional drop precedent data wherein the drop precedence data defines a further packet drop priority within the control signaling class and the voice class. The apparatus and method drops a queued classified wireless communication packet based on a priority level of assigned drop precedent data and based on the packet classification data.

Abstract: At least one transmission condition associated with making a transmission of pre-cache data over a transmission leg ( 112 or 114 ) of a network is obtained. A priority for transmitting the pre-cache data is determined using the transmission condition.

Abstract: Various embodiments are described for establishing a group call session serially. After receiving a serial group call request from a remote unit (101), fixed network equipment (FNE) (201) selects a first subset of members (260) from the targeted group (250) of units and signals those members to join the group call session. Various techniques for selecting the first subs et may be employed depending on what system benefits are desired. A second subset of members (270) from the targeted group of units is also selected an d signaled to join the session. This second subset may be used to invite additional units in order to achieve a maximum number of group participants. Alternatively, the second subset may be used to invite a different unit ( or units) to participate. This can be triggered by a user request to invite another subset to the group session, as could occur when the user is not able to resolve the particular matter at-hand with the group members of the first subset.

Abstract: A communication device (202) converts a bit stream to multiple symbols and provides encryption at a physical layer by shifting a phase of each symbol of the multiple symbols to produce multiple encrypted symbols. Each encrypted symbol of the multiple encrypted symbols is modulated with an orthogonal (214) subcarrier to produce at least one modulated subcarrier and the at least one modulated subcarrier is then transmitted (278) via a wireless link. On a receive side (260), a receiving (260) communication device (250) receives the transmitted (230), encrypted symbols and provides decryption at a physical layer by shifting a phase of each encrypted symbol in correspondence with the phase (234) used to encrypt the symbol at the transmit side.

Abstract: To address the need for an interference-efficient method and apparatus to provide CDMA services, embodiments of the present invention adjust the outer loop frame error rate (FER) target on the forward and reverse links (110-113) while providing communication services to remote units (101-102). At times during a service when a link is conveying primarily "empty" eighth rate frames, the FER target for that link is increased. This improves system capacity by effectively reducing the power needed to transmit such frames and thereby reducing the resultant interference.

Abstract: To address the need for reducing audio overhang in wireless communication systems (e.g., 100 ), the present invention provides for the deletion of silent frames before they are converted to audio by the listening devices. The present invention only provides for the deletion of a portion of the silent frames that make up a period of silence or low voice activity in the speaker's audio. Voice frames that make up periods of silence less than a given length of time are not deleted.
