摘要： 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.

摘要： In the present invention, the subscriber unit (200) obtains a set of access point identifiers and measurement opportunity information for each access point identifier. A first measurement is performed on a first access point identified from the set of access point identifiers. A current timer value is determined after completing the step of performing, and a second access point identified from the set of access point identifiers in which to perform a second measurement is selected. Selecting the second access point is based on at least the measurement opportunity information for the second access point in relation to the current timer value.

摘要： The invention provides an enhanced passive scanning method for a wireless local area network, including the steps of transmitting at least one of a beacon signal or a gratuitous probe response in a WLAN channel by an access point. The gratuitous probe response is a supplemental beacon signal that is transmitted at intervals between the occurrence of regular beacon signals, but contains only essential information to allow mobile station manage roaming and timing.

摘要： A wireless communication unit (120) polls (200) a radio access point (110) at a certain frequency. The wireless communication unit (120) then determines (210) whether packets are received in response to the polling and determines (220) the percentage of polls resulting in receipt of packets. The wireless communication unit (120) then adjusts (230) the polling frequency to change the number of polls which result in the receipt of packets. Optionally, the wireless communication unit (120) repolls (240) the radio access point (110) when a packet in not received. Then, the wireless communication unit (120) plays (250) the packet at a certain time. Alternatively, the wireless communication unit (120) receives (310) packets without polling and determines (220) a radio access point frequency at which packets arrive at the radio access point (110). The polling frequency is then set (330) to approximately the radio access point frequency.

摘要： A Session Initiation Protocol (SIP)-compliant proxy (106) receives a first INVITE message destined for a mobile station (102). The first INVITE message is associated with an initial Internet Protocol (IP) contact address for the mobile station (102). Subsequently, it is determined whether an IP address update for the mobile station (102) may have occurred and a new IP contact address is obtained for the mobile station (102). A second INVITE message is sent to the mobile station (102) at the new contact address so as to continue a session initiation.

摘要： 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.

摘要： 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.

摘要： 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.
