Abstract: In a wireless communication system (100) having a plurality of communication cells (115, 117), and a plurality of mobile stations (118) operating within selected ones of the multiple communication cells (115, 117), a method and a n apparatus for selecting those communication cells (115, 117). Within each communication cell (115, 117), a base station (112) transmits a message directed to the mobile stations (118), and detects a response indicator in t he selected ones of the plurality of communication cells (115, 117). The respon se indicator may be an impulse radio-frequency energy transmission generated by the plurality of mobile stations (118) operating within the selected ones of the plurality of communication cells (115, 117). The base station (112) directs call traffic to the plurality of mobile stations (118) in the select ed ones of the plurality of communication cells (115, 117).

Abstract: A quality dispatch service on a CDMA based wireless system (50). To achieve spectral efficiency and fast access for follow-up calls, in response to a request by a talkgroup member (A-D) to have a group call established, the non-requesting (listening-only) members (B-D) are allowed to establish a low-rate (non-voice) signaling link (54-56) in the reverse direction (inbound) for the limited purpose of (i) providing forward power control information to the fixed infrastructure; (ii) requesting soft hand-off when required; and (iii) maintaining the correct reverse link power control to allow for fast channel access for a follow-on call.

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: An Access Point (AP) (110) receives a first set of timing information comprising timing information for at least one neighboring AP (111-113) and conveys, to a user equipment (UE) (103), a second set of timing information comprising timing information for the at least one neighboring AP, wherein the second set of timing information is derived from the first set of timing information. Based on the second set of timing information, the UE is able to determine a time to scan the at least one neighboring AP. In various embodiments of the present invention, the AP may receive the first set of timing information from another UE (102) or may receive the timing information without the involvement of the another UE, for example, via a network interconnecting the APs or by monitoring an air interface of the at least one neighboring AP.

Abstract: Methods and apparatus are provided for facilitating mobility of a mobile station (MS) in a wireless local area network (WLAN) with uninterrupted communications. The method includes associating (501) a MNIP address (410) with the MS; establishing (502) a communications link between the MS and a first WLAN AP (109) in a first subnet (117) and associating (503) a first WLAN IP (420) address with the MS. Then using (505) the first WLAN IP address for an application that benefits from a persistent connection. Further included is establishing (507) a second communications link between the MS and a second WLAN AP 111 in a second subnet (119). When the MS is using the application, continuing to use the first WLAN IP address for communicating with the second subnet; and requesting (517) a second WLAN IP address in the second subnet when the persistent connection is no longer needed.

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.

Abstract translation: 本发明提供了一种用于无线CDMA通信系统中的群组呼叫的方法和装置，解决了在CDMA群组呼叫中对可靠和有效的反向功率控制的需要。 通信基础设施（108-110）在从通信单元（例如，103）接收到群组呼叫请求时，在每个小区中分配单个话音信道（例如，120-121），该小区向 组（101）。 通信基础设施还向组中的每个通信单元分配反向功率控制信道（例如125-127）。 因此，该组的每个通信单元经由通信单元的站点或小区中的语音信道接收用于组呼的语音信息，并且每个通信单元经由分配给该通信单元的站的反向功率控制信道接收入站（即，反向）功率控制信息 通讯单元 以这种方式，本发明有效地向多个通信单元提供反向功率控制信息，因此有助于在CDMA系统中建立组呼。

Abstract: A controller, in response to receiving a request for a group call (201), allocates at least one power adjustment channel to the group call (202) and sends identification of the at least one power adjustment channel to at least some of the subscriber units in the group (203). Using the at least one power adjustment channel, the controller also sends unique power adjustment information to each of the at least some subscriber units (204).
