    Abstract: A new data circuit equipment (DCE) (303) coupled to an IWF (115) and a terminal adapter (TA) (306) coupled to a mobile station provide interconnection within a RF communication system such that Class 2 service common to wireline network equipment can be beneficially employed in the wireline RF communication system. The new DCE (303) and TA (306) are transparent to external wireline systems while maintaining compatibility with, inter alia, the predetermined data service protocol layers of the RF communication system, the RF air-interface and/or radio link protocol (RLP) of the RF communication system.

    Abstract: A mobile station (106) establishes a real time communication link via an access point (102) for carrying voice or other time-sensitive data. A WLAN subsystem (204) of the mobile station is normally kept in a low power state. Upon initiating a communication link the mobile station signals to the access point that uplink poll-based power save delivery mode will be used (614), and the access point reserves resources to assure the necessary quality of service. The mobile station initiates a frame transaction by first powering up the WLAN subsystem (712), acquiring the WLAN channel (407), and transmitting a polling frame. Upon successful receipt of the polling frame the access point prepares to reply with a response frame at an unspecified time within service window, during which time the mobile station maintains the WLAN subsystem power up and ready to receive the response frame. Upon successful receipt of the response frame, the mobile station places the WLAN subsystem back into a low power state.

    Abstract: A communication method can inform a WLAN-to-WAN handoff process as a function, at least in part, of a determined likely future quality of service (35). In particular, a comparison (36) can be made as between the likely future quality of service being afforded by the WLAN and one or more threshold values that represent acceptable levels of service. In one embodiment projected likely quality of service values as correspond to different future points in time can be used to more completely inform the evaluation process.

    Abstract: To address the need for an apparatus and method for CDMA-dispatch soft handoff, the present invention enables base-initiated soft handoff for dispatch calls. A mobile station (120) in a dispatch call establishes an individual inbound link (137) with the serving base site (111). The serving base site and one or more adjacent base sites (e.g., 110 and 112) determine the signal quality of the inbound link transmissions of the mobile station. The adjacent base site with the highest received inbound link signal quality is selected as the target soft handoff site. The serving base site then transmits the handoff information to enable the mobile station to begin a soft handoff with the target site.

    Abstract: A wireless two-way communications apparatus ( 700 ) having a radio resource manager ( 706 ) is configured and arranged to effect one or more modes of operation ( 203, 204, 206 , and 207 ) as a function, at least in part, of whether the apparatus is presently operating in a power saving mode of operation ( 201 ) and/or is presently supporting an active plesiochronous communication session ( 202 and 205 ). Pursuant to one approach, when the apparatus is operating in a power saving mode of operation and presently supports such a communication session and when the apparatus further determines ( 301 ) that a wireless access point beacon or supplemental beacon is at least largely coincident with a scheduled active window of that communication session, the apparatus can determine ( 302 ) whether to facilitate rescheduling a next monitoring of the beacon or supplemental beacon and/or altering the scheduled active window itself to thereby render the beacon or supplemental beacon monitorable by the apparatus.

    Abstract: To address the need for an apparatus and method for CDMA-dispatch soft handoff, the present invention provides soft handoff to mobile stations (MSs) ( 120-123 ) in a dispatch call by sharing soft handoff information with all the MSs in the call at a base site ( 111 ). When a first MS (e.g., 120 ) needs to soft handoff, the identity of a soft handoff channel ( 135 ) at an adjacent base site ( 112 ) is shared with all the MSs. Thus, subsequent MSs (e.g. 122 ) that need to soft handoff to that adjacent base site may do so without requesting a soft handoff.

    Abstract: The present invention provides a method and apparatus for group calls in wireless CDMA communication systems, addressing the need for reliable and efficient reverse power control in CDMA group calls. A communication infrastructure (108-110) upon receiving a group call request from a communication unit (e.g., 103), allocates a single voice channel (e.g., 120-121) in each cell that provides service to one or more communication units of the group (101). The communication infrastructure further allocates a reverse power control channel (e.g., 125-127) to each communication unit of the group. Thus, each communication unit of the group receives voice information for the group call via the voice channel in that communication unit's site or cell, and each communication unit receives inbound (i.e., reverse) power control information via the reverse power control channel allocated to that communication unit. In this manner, the present invention efficiently provides reverse power control information to multiple communication units and, therefore, facilitates the establishment of group calls in CDMA systems.
