In telecommunications, basic service is: 1. A pure transmission capability over a communication path that is virtually transparent in terms of its interaction with customer-supplied information. 2. The offering of transmission capacity between two or more points suitable for a user's transmission needs and subject only to the technical parameters of fidelity and distortion criteria, or other conditioning.

System for transactionally deploying content across multiple machines

A system for transactionally deploying content across multiple machines in a network environment automates and synchronizes secure and reliable distribution of digital assets to multiple network locations, allowing controlled provisioning and synchronization of code and content updates to live applications. A distributed architecture includes at least one receiver—a secure listener configured to process incoming distribution jobs—and at least one base server—a sender that may also act as a receiver. An administration interface allows administrative and reporting services and deployment management. Using the administrative interface, users are enabled to launch, simulate, schedule and monitor activities for any network location at any time. The system provides fan-out and multi-tiered deployment topologies expandable to hundreds of servers. Each deployment is fully transactional, permitting rollback of the system to it “last known good” state in the case of failure.

Method and system for using basic service set identifiers (BSSIDs) for emergency services routing

A plurality of public safety answering points (PSAPs) are accessible via a voice-over-packet (VoP) network. Each wireless access point of the VoP network is identified by a basic service set identifier (BSSID). A mobile node associates with a wireless access point and stores the wireless access point's BSSID as an indicator of the mobile node's location. A user of the mobile node dials digits for an emergency services call. In response, the mobile node transmits a SIP INVITE message that includes the BSSID and an additional indicator of the mobile node's location, e.g., determined using GPS or tower triangulation. A SIP proxy server receives the SIP INVITE message and attempts to determine the appropriate PSAP to answer the call based on the BSSID. If the attempt is unsuccessful, the SIP proxy server determines the appropriate PSAP based on the additional indicator.

System and method for building wireless applications with intelligent mapping between user interface and data components

A system and method is described for effective management of a User Interface (UI) of a wireless device by implementing direct mapping between the application data domain and UI screens and controls. The device has an intelligent wireless device runtime environment (Device Runtime) that provides a set of basic services to manage the wireless application, including a series of linked screen and data component definitions, and their interactions can simplify the development effort and reduce resource allocation. The data domain for this category of applications is defined using the atomic data component definitions. The communication between a device user interface and data components is defined using atomic screen component definitions. Both screen and data component definitions are described in metadata using a structured definition language such as XML. The relationships between the screen and data component definitions are embedded in the XML definitions in the form of screen / data mappings. Typically, rendered screens for display are derived from some underlying data component and screens controls affected by user events impact the current state (or data representation) of the application Changes to the application domain data are automatically synchronized with the user interface, and user-entered data is automatically reflected in the application domain data. The primary mechanism behind this synchronization is the mapping of screens and data. This mechanism enables creation of dynamic and interactive screens. All changes to the data component can be immediately reflected on the screen and vice versa. This model allows building effective wireless applications based on server-to-device notifications. The data updates asynchronously pushed from the server are instantaneously reflected at the UI screen.

In an embodiment of the invention, a method for servicing a first set of wireless stations operating on a first channel of an access point and a second set of wireless stations operating on a second channel of the access point comprises transmitting, at a first time, a first frame from the access point to the first set of wireless stations via the first channel, the first frame having duration data directing the first set of wireless stations to cease transmitting until a second time represented by the duration data and servicing the second set of wireless stations via the second channel of the access point for at least a part of a time period between the first time and the second time. The method further comprises transmitting, at the second time, a second frame from the access point to the second set of wireless stations via the second channel, the second frame having duration data directing the second set of wireless stations to cease transmitting until a third time represented by the duration data of the second frame and servicing the first set of wireless stations via the first channel of the access point for at least a part of a time period between the second time and the third time. The method also may comprise transmitting a Delivery Transmission Indication Map (DTIM) frame prior to transmitting each of the first and second frames. The transmission of the DTIM frame preferably occurs substantially simultaneously with a Target Beacon Transmission Time (TBTT) of the access point.

Control of Quality of Service in Overlapping Basic Service Sets in Wireless Local Area Networks

Access priority for wireless devices located in an area in which radiofrequency (RF) coverage areas of a first wireless access point and a second wireless access point overlap is controlled by coordinating operation of the first wireless access point and the second wireless access point. The wireless devices access a common RF channel via a collision sense multiple access / collision avoidance mechanism. The probability of accessing the RF channel may be varied by adjusting the length of interframe spacings and the length of contention windows. The length of the interframe spacings and the length of the contention windows associated with the first access point and associated with the second access point are configured such that the probability of wireless devices associated with the first wireless access point accessing the RF channel is greater than the probability of wireless devices associated with the second wireless access point accessing the RF channel.

A system of a wireless local area network (LAN) based on transmit power control comprises: an access point (AP) for broadcasting a beacon frame to an area that is outside a service coverage of a first transmit power by using a second transmit power higher than the first transmit power already set when it reaches a set period, and for increasing the first transmit power if there is a request for increase of the first transmit power based on the beacon frame broadcast by the second transmit power; and a station which requests an increase in the first transmit power on the basis of the received beacon frame so as to enable the station to have an association with the AP. The increase is requested when the station receives the beacon frame broadcast from the AP with the second transmit power when the station is outside the service coverage of the first transmit power.
