Abstract: A mobile communication device (102) includes both a wide area network (WAN) radio modem (122), and a personal area network (PAN) radio modem (134), which operate on similar frequencies. When the both the WAN and PAN modems are operating and carrying time-sensitive data, the WAN modem disables transmission by the PAN modem when the WAN modem is due to receive data from a WAN base station (406), including neighbor scans. The duration and frequency of disabling the PAN modem is controlled so that the retransmission is successful.

Abstract: The invention concerns a method (200) and system (100) for setting a paging indication sequence (512) in paging messages (510). In one arrangement, the method can include the steps of - in a mixed media environment - receiving (212) incoming traffic designated for one or more mobile stations (112) in a paging group in which the mobile stations are capable of operating time-critical applications and ordering the paging indication sequence of the paging messages. The ordering can be performed such that higher priority identifiers (514) associated with the time-critical applications are positioned in front of lower priority identifiers (516) to reduce the connection set-up time for the time-critical applications of the mobile stations. As an example, the time-critical applications may be real-time applications, and the lower priority identifiers may be associated with non-real-time applications.

Abstract: A method (200) and system (100) for supporting fast connection set-up in a communication network (110). The method can include the steps of - in a mobile station (114) that is capable of operating in at least two separate power saving modes, a first power saving mode and a second power saving mode, entering (212) an operational state associated with the second power saving mode and staying (214) in the first power saving mode. This process can enable the mobile station to avoid entry into the second power saving mode during the operational state. In the first power saving mode, the mobile station may remain registered with a communication network. In the second power saving mode, the mobile station may be de-registered from the communication network. The first power saving mode can be a sleep mode, and the second power saving mode can be an idle mode.

Abstract: The invention concerns a method (200) and system for improving transmission or receipt of channel descriptors. The method can include the steps of - in a wireless communication system (100) that periodically broadcasts regular channel descriptors (310) at a set interval (312) - changing (212) a modulation scheme and transmitting (216) one or more supplementary channel descriptors (314) during the set interval between regular channel descriptors. The method can also include the step of periodically transmitting (214) a channel descriptor count (412) that provides an indication of the changed modulation scheme.

Abstract: A mobile station (204) in a wireless local area network is associated with an access point (202), which controls timing of certain transmissions, such as beacons (402). The mobile station has a timer (108) that is driven by a high frequency clock source (110) while operating in an active mode, and a low frequency clock source (112) when in a low power mode, to conserve battery charge. To prevent timing errors from significantly affecting the accuracy for the timer (108) upon transitioning from one mode to the other, access point transmits timing information to the mobile station in the course of servicing requests from the mobile station. The timing information is included in a response sequence (300).

Abstract: 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.

Abstract: A mobile communication device (102) includes a wide area network (WAN) modem (122) for communicating over a wireless WAN. During a voice call, the WAN modem operates in a power save mode (206) but must occasionally scan for handover candidate base stations (208). The modem goes directly from the power save mode to a scan mode at an agreed upon time, first selected by the mobile communication device, but which may be modified by the base station.

Abstract: A wireless local area network (WLAN) includes an access point (102) and a mobile station (106). The mobile station can operate in a low power mode by shutting down a WLAN subsystem (204) of the mobile station. While the mobile station is in a low power mode, the access point buffers data received at the access point destined for the mobile station (706). The mobile station wakes up to initiate a service period by transmitting a trigger frame to the access point, and identifies a traffic stream to be serviced in the presently initiated service period. The access point begins transmitting response frames to the mobile station, identifying the traffic stream requested by the mobile station, and in at least one response frame, the access point may indicate the buffer status of another traffic stream associated with the mobile station to allow the mobile station to make decisions regarding data retrieval and power save state.
