摘要:
The present invention provides a method and apparatus that features initiating a device discovery process for attempting to establish a connection between two or more devices via short range communications technology, wherein at least one of the two or more devices having an existing link to another wireless network; and suspending the link to the other wireless network before starting the device discovery. One of the devices may be a node, point or terminal, including a station or access point. The wireless network may include a wireless local area network (WLAN), Bluetooth® (BT), ultra wide band (UWB), wireless USB or other suitable wireless network either now known or later developed in the future. The short range communications technology may include Bluetooth®, as well as other short range communications technology either now known or later developed in the future.
摘要:
The present invention provides a new and unique method and apparatus for detecting in a short-range communication device, such as a WLAN station (STA), the trend in WLAN signal strength based on one or more characteristics, e.g. received signal strength values and current time of their observation, by fitting a generalized linear model to the values. Based on the detected trend, three things can be inferred: 1) WLAN radio coverage available for STA is strengthening, 2) WLAN radio coverage available for STA is stationary, or 3) WLAN radio coverage available for STA is weakening.
摘要:
The present invention provides a method and apparatus featuring performing detection functionality to determine if a wirelessly connected node, point or terminal in a wireless network configured to operate according a predefined power saving scheme operates incorrectly; and adjusting the predefined power saving scheme when wirelessly connected with the particular node, point or terminal if an incorrect power saving operation is detected. The detection functionality may include probing types of power saving protocol tests and using lower and higher-layer protocol information to detect if the mobile device might be missing some data. The adjusting may include: 1) disabling the predefined power saving scheme, or 2) switching entering into the predefined power savings scheme only after a predefined inactivity period, wherein the predefined inactivity is substantially longer than in “normal” operation.
摘要:
A system for managing the operation of a plurality of radio modules integrated within the same wireless communication device. In at least one embodiment of the present invention, a control strategy may be employed to regulate the quality level of a signal delivered by a codec in order to balance the performance realized in the reproduction certain signals with overall communication stability in the wireless communication device. The regulation of signal quality level may be affected by reducing the bit rate of a codec, changing the codec to select another codec with a lower bit rate, or by performing bitrate scaling with the codec signal.

A method includes storing a table that contains identifications of certain ones of network devices and, when operating a wireless network access node in a hidden mode of operation, transmitting a probe response only to a probe request that is received from a network device having an identification stored in the table.
摘要:
Apparatus, and an associated method, for facilitating identification of primary, secondary, and hidden SSID values in a multi-network WLAN system. A determiner embodied at a mobile terminal determines primary SSID values of networks whose beacon signals are delivered to the mobile terminal. And, responsive to the determinations, further determinations are made as to where to send subsequent probe requests to probe for secondary or hidden SSID values associated with the access points from which the beacon signals are broadcast. Thereafter, selection is made of the network with which the mobile terminal shall communicate.
摘要:
A system and method for using licensed radio technology for determining the operation parameters which should be used by a terminal. The present invention involves the terminal using its GSM system, if activated, to determine whether mobile country code for a nearby cellular terminal is located within the United States or Canada. If the code designates the United States or Canada, then the terminal uses the US domain and the corresponding transmission channels and power levels. If the code does not designate the United State or Canada, then an ETSI domain is used, along with the appropriate transmission channels and power levels.
摘要:
A new and unique method or apparatus for power savings in a node, point, terminal or device in a wireless local area network (WLAN), or other suitable network, featuring one or more steps for delaying forwarding one or more data packets from a WLAN chipset to a host processor based on information received by the WLAN chipset about whether the host processor is in a sleep state. The host processor has a clock request pin to indicate when it is in the sleep state. The WLAN chipset has a pin that is connected to a sleep state signal of the host processor so that the WLAN chipset knows when it can wake up the host processor or not. The WLAN chipset has an internal threshold timer to fulfil latency requirements for delivering packets to the host processor.

The invention relates to applying a handover algorithm in a mobile terminal. In the method, the state of a user interface component of the terminal is checked, and the handover algorithm is applied on the basis of the current state of the user interface component. The handover algorithm is applied only if the current state of the user interface component is active.
摘要:
The invention relates to a method for arranging handover in a wireless telecommunications system. Connection settings are stored in a terminal, wherein at least one network identifier is associated with alternative connection settings, the network identifier identifying a target network reachable by a connection from the terminal. The network identifier associated with the currently applied connection settings is compared with the network identifiers associated with the other available connection settings. The connection settings associated with the same network identifier as the one associated with the currently applied connection settings are then selected. The handover may then be carried out by using the selected connection settings.
