Publication number: 20080316976Abstract: A basestation 3G1x network architecture which is used to convert 3G1x control and signaling to IMS/SIP in basestation is disclosed. The system includes a user agent that bi-directionally translates between SIP messaging and CDMA messaging. The system also includes a 1x basestation emulator which may act as an interface for the 3G1x handset. The basestation emulator is also configured to terminate CDMA mobile protocol and interconnect messages and operations with the user agent. The methods include mapping between the CDMA mobile message and the SIP message through the basestation emulator and the SIP user agent. The method may facilitate basestation origination and termination as well as feature services. These feature services may include three way calling, call waiting and call waiting with caller identification.Type: ApplicationFiled: June 25, 2007Publication date: December 25, 2008Applicant: LUCENT TECHNOLOGIES, INC.Inventors: Robin Jeffrey Thompson, Alex Lawrence Wierzbicki

Publication number: 20080316977Abstract: Systems and methodologies are described that facilitate employing a hybrid transmission structure in a wireless communication environment. Each transport block (e.g., MAC PDU) can be split into multiple code blocks. Moreover, each of the code blocks can be further divided into two or more code block segments. Further, code block segments from a given code block can be transmitted over a channel during disparate time slots of a subframe. Also, within a given subframe, code block segments corresponding to differing code blocks can be transmitted sequentially in time. Utilization of the foregoing can enable employment of a pipelined decoder structure at a receiver while allowing for optimization of time/frequency diversity.Type: ApplicationFiled: June 24, 2008Publication date: December 25, 2008Applicant: QUALCOMM IncorporatedInventor: Durga Prasad Malladi

Publication number: 20080316978Abstract: A transmit and receive machine (TRM) is part of a medium access controller (MAC), in support of the 802.11 wireless standard. The TRM is a control machine that changes the MAC within which it resides from a purely software-based MAC into a software and hardware management system. Timing-critical tasks that were once performed by the embedded processor of the MAC are performed by the TRM. This change enables the MAC to operate at a high speed while the TRM maintains high accuracy of transmit and receive timing operations.Type: ApplicationFiled: June 19, 2007Publication date: December 25, 2008Inventors: Levi Ronen, Oded Liron

Publication number: 20080316979Abstract: The claimed subject matter relates to configuring a host device through utilization of MMP, which is a protocol that is based upon MIP but not associated with several deficiencies associated therewith. In particular, a wireless terminal can be configured to run MMP and send messages that conform to MMP over a wireless link. A base station can be configured to act as a DHCP server. The base station can provide configuration information to host device by way of DHCP.Type: ApplicationFiled: July 14, 2006Publication date: December 25, 2008Inventors: Rajiv Laroia, Prasanna Nadhamuni, Rick Dynarski, George Tsirtsis, Vincent D.

Publication number: 20080316980Abstract: The present invention relates to an arrangement comprising a functional server node forming part of a conglomerate, or pool, of functional server nodes in common controlling a number of radio network control means, each functional server node being able to control any, or a number of, radio network control means, to which mobile stations are connected. The functional server nodes support transfer/redistribution of mobile stations between each other without interrupting the connection of the mobile stations, a target functional server node, to which it has been decided that a mobile station is to be transferred from a current functional server node, generates an area update or transfer acceptance message comprising an identification of the current functional server node, an identification of the target functional server node and a transfer indications. The invention also relates to a method of redistributing or transferring mobile station contexts.Type: ApplicationFiled: August 28, 2004Publication date: December 25, 2008Inventors: Anders Ahlen, Niklas Sven Lundin, Staffan Winell

Publication number: 20080316981Abstract: A control frame transmission algorithm is disclosed for 802.11n devices operating in a wireless neighborhood that includes both high-throughput (HT) devices and non-high throughput devices. The control frame transmission algorithm establishes the characteristics of a control frame initiated by the station, as well as the characteristics of a response control frame, which is sent in response to a frame received from another station. These characteristics include the PHY protocol data unit format, the transmission rate, and modulation coding scheme to be used.Type: ApplicationFiled: June 19, 2007Publication date: December 25, 2008Inventor: Solomon TRAININ

Publication number: 20080316982Abstract: Techniques for enhancing the throughput capacity available to client devices connected to a wireless local area network (WLAN) are described. Specifically, existing WLAN resources are converted into wireless access points (APs) to create a dense infrastructure of wireless APs. To leverage this dense AP infrastructure, central management techniques are employed. With client-to-AP mapping, these techniques are used to prevent the discovery of multiple APs in a WLAN by a client device and to select a single AP (using certain policies) to associate with the client device and provide it with an enhanced wireless connection to the WLAN. Additionally, techniques are employed to centrally determine, using central policies, when the AP should disassociate from the client device and when another centrally selected AP should respond to, and associate with, the client device to provide it with an enhanced wireless connection to the WLAN—without interrupting/disrupting the client device's access.Type: ApplicationFiled: June 20, 2007Publication date: December 25, 2008Applicant: Microsoft CorporationInventors: Rohan N.

Publication number: 20080316983Abstract: A LAN access point maintains service information that defines which of a plurality of network service levels is allocated to a plurality of communication terminals. The LAN point regulates the network service levels that it provides to the communication terminals in response to the service information. The service information may allocate different maximum communication bandwidth levels and/or allow/deny access to various network services to defined communication terminal identifiers, identifiers route locations hosted on communication terminals, and/or identifiers for users of the communication terminals. Moreover, the service information may define a time of day schedule and/or day of week schedule that varies the allocation of maximum communication bandwidth levels and/or access to various network services.Type: ApplicationFiled: June 22, 2007Publication date: December 25, 2008Inventor: Brian Daigle
