摘要： An apparatus and method for switching a mobile processing device from communicating over a wireless connection with a first base unit to a second base unit based upon latency. In accordance with this invention, the mobile processing device determines latency information for packets being transmitted over the wireless connection to and from a base unit. The latency information is compared to a threshold value. If the latency information is greater than the threshold value, the mobile processing device adjusts parameters of the wireless connection between the mobile processing device and the network.

摘要： A method, an apparatus, and code in a carrier medium to operate in a first access point of a wireless network in communication with at least one associated client station. The method includes wirelessly broadcasting a management frame including an indication that the first access point will stop being active, such that each associated client station can wirelessly roam to a second access point prior to the first access point ceasing being active. One embodiment further includes reducing the transmit power of wireless communication used to wirelessly transmit information to the associated client stations, such that each associated client station can eventually wirelessly roam to the second access point.

摘要： The present invention detects a micro-roaming client in a WLAN. Once a micro-roaming client is detected, APs coordinate with each other and assign the client to a specific AP. In an embodiment, a user-configurable anchor timer for micro-roaming clients is provided, so that when the timer has expired, the client is free to roam within the overlapping cell until it becomes anchored to an AP again. In various embodiments, environmental variables can affect APs to release an anchored client to roam again. These environmental variables may include low RSSI from the client, a high percentage of frame loss to the client, or a low data rate. The present invention also provides a new protocol that is resilient and self-sustaining with minimal user configuration required.

摘要： A technique whereby a subscriber of a multiple access communication network such as a cellular communication system is permitted to make a reservation to guarantee availability of a shared physical communication resource, such as a cellular radio telephone traffic channel, at an appointed date, time and location. The reservation is made in advance by the subscriber requesting the network to mark a requested resource for the subscribers exclusive use during the requested period of time. The reservation may be made any number of ways, such as through the subscriber terminal itself, by making arrangements themselves or on their behalf by others at a conference call center, through Web servers connected through the Internet, or by other means. Whenever a resource of the requested type is available during the requested period, the controlling stations in the network reserve that resource for that subscribers' exclusive use as the appointed time draws near. Thus, when that subscriber attempts to originate or is expected to receive a call at the appointed time, the network is able to grant the on-hold resource to that subscriber. After the reserved period of time elapses, the network releases the reserved resource, and applies normal allocation rules to it.

摘要： A technique for implementing Special Call Services (SCS) to extend wireless system functionality to include private emergency or other types of service-specific special calls in a private network. In a preferred embodiment, the capability is implemented by taking advantage of certain service type elements that may be coded in the Radio Resource Management (RR) functional layer channel request message and/or the Mobility Management (MM) functional layer call request messages in a Global System for Mobile (GSM) communication system. Specifically, an establishment cause field in a RR channel request message and/or a service type field in a MM request message is used to request such services from the network. These establishment causes and service types can be defined, but not limited to, using those codes currently defined as reserved by GSM Version 4.08, Section 9.1.8 and Section 10.5.3.3. Thus, these newly added codes do not require any re-programming of the deployed GSM equipment and impact on their current operation, either. A GSM system that implements the invention preferably contain a Radio Resource (RR) functional entity that watches for a newly added SCS causes and takes them into account when granting physical resources to the requesting unit. Such actions may include, but are not limited to, dropping a normal call-in-process in order to accommodate the SCS call if there are no free physical resources left, prioritizing SCS calls in progress, or other techniques for allocating a physical channel to the SCS channel request. Such techniques may include allocating radio resources which are reserved in advance for the SCS cause.

摘要： A method for handover execution in a wireless environment is provided that comprises communicating, by a mobile network, a handover command message to a physical layer of a mobile station to initiate a handover execution. The handover command message is received by the physical layer, which responds by tuning to a handed to frequency and by communicating physical layer bursts over the handed to frequency such that initial timing advance and power control setting characteristics are determined by the mobile network. The method also includes communicating a cease signal to stop communicating the bursts to the mobile station, which responds by ending the transmission of the bursts and by establishing a new communications link over the handed to frequency with the mobile network. The mobile station and mobile network may then couple to a voice or data path such that a wireless communication associated with the mobile station and the mobile network is facilitated.
