Abstract: Techniques for inter-frequency neighbor list searching are disclosed. Embodiments disclosed herein address the need for inter-frequency neighbor list searching. In one embodiment, a searcher is deployed to search a PN space with a first set of search parameters and to return search results. A subset of those results is selected, along with a previously saved search result, to form a set of PN locations for a second search. The second search is performed on a window around each of the PN locations, using a second set of search parameters. The maximum peak from the second search is saved for use in future iterations. In one embodiment, the subset is selected as the highest energy level peaks from the first search. In one embodiment, if a maximum peak is deemed to correspond to a valid base station when the position of that maximum peak is within a pre-determined time offset from a previous maximum peak.

Abstract: A self-service distribution configuration framework integrates with a directory services and Systems Management Server (SMS) of an enterprise computing system for web based self service configuration changes on a server owner defined schedule. The framework will cross reference the SMS database with the configuration framework database and dynamically update or create SMS server collections and advertisements for each unique time and day selected. For example, all systems that have had “Monday at 8 PM” selected as their scheduled date and time would become a member of the same collection. Upon opening the web site, the system owner is presented a data grid populated with a list of servers for which the individual is responsible, enabling selection of specific days and times for each server at which configuration changes sent by the SMS will occur.

Abstract: In various embodiments, communication apparatuses and methods for providing robust communications are disclosed. For example, an apparatus may establish an air interface in accordance with an orthogonal frequency division multiplex (OFDM) protocol. According to another particular aspect, the apparatus establishes an air interface in accordance with a Fast Low-Latency Access with Seamless Handoff Orthogonal Frequency Division Multiplex (FLASH-OFDM) protocol.

Abstract: A communications device, e.g., a mobile wireless terminal, includes a plurality of antennas having different polarization directions. The plurality of antennas includes a first antenna and second antenna which are operated in a coordinated fashion. During reception a signal received via the first antenna is subjected to a phase shift operation before being combined with a signal received via the second antenna. During transmission a signal to be communicated is subjected to a phase shift operation and the phase shifted signal is transmitted over the first antenna while the non-phase shifted signal is transmitted over the second antenna. The amount of phase shift is a function of the difference in polarization directions between the first and second antennas. The novel antenna configuration facilitates the use of the horizontal polarization direction communications between the communications device and a base station without the need for directionally positioning one or more electrical antennas.

Abstract: Techniques for minimizing call setup latency are disclosed. In one aspect, a channel assignment message is sent with a flag to direct the use of previously negotiated service parameters. This aspect eliminates the need for service negotiation messages. In another aspect, a channel assignment message is sent with an active set identifier instead of an active set and its parameters. This aspect reduces the transmission time of the channel assignment message. In yet another aspect, call setup without paging is facilitated by a mobile station (106) sending a pilot strength measurement message between active communication sessions, such that a channel assignment message can be used for mobile station terminated call setup without the need for mobile station paging and related messages.

Abstract: In accordance with a method for increasing the capacity of a channel in a communications system, characteristics of a channel may be evaluated. The channel may include a plurality of slots, and the slots may have a slot format among a set of slot formats. A slot format among the set of slot formats may be selected. The selection may be based on the evaluated characteristics of the channel. Selecting the slot format may include selecting the position of a signal within each of the plurality of slots. The position of the signal may be different for each of the slot formats. The signal may be transmitted in each of the plurality of slots over the channel.

Abstract: In a method and apparatus for providing system interoperability in wireless communications an IP based client-server application maintains a proper set of PDP contexts while a mobile is connected via an IP based system. The application client resides in the mobile and the server resides within the network at a common anchor point between the IP based system and a PDP contexts based system. The PDP contexts are kept up to date but on hold until a handover occurs for the mobile from the IP based system to the PDP contexts based system.

Abstract: The claimed subject matter relates to providing appropriate QoS treatment to one or more traffic flows associated with a terminal, wherein the QoS treatment is defined within a profile assigned to the terminal and implemented when the terminal requests access to a network. An access mode can receive identifying indicia associated with the terminal and relays such indicia to an authentication and authorization server (AAS). The AAS can thereafter provide the access node with a profile that defines QoS treatment to associate with one or more traffic flows related to the terminal.

Abstract: In general, this disclosure is directed to establishment and release of a connection between a communication device and an access network. More specifically, the techniques of this disclosure are directed to determining when a data flow used for exchanging call control requests becomes inactive. For example, a communication device may dynamically adjust an inactivity timer threshold associated with the data flow used by applications to exchange call control messages when a new call control transaction starts or an existing call control transaction ends, e.g., by selecting a single inactivity timer threshold for the data flow to satisfy minimum connection requirements of existing call control transactions, recently ended call control transactions and the new call control transaction. The data flow is considered inactive when no applications send or receive messages via the data flow for a period of time that exceeds the adjusted inactivity timer threshold.

Abstract: Using split interfaces for Internet Protocol version 6 (IPv6) and Internet Protocol version 4 (IPv4), and bridging the IPv4 interface, makes it possible to support a Tethered Device (TD) and an Access Terminal (AT) having concurrent IP connectivity. This configuration enables the support of IP Multimedia Subsystem (IMS) applications in the AT using IPv6 while concurrently supporting general Internet usage on a TD. It is also possible to bridge an IPv6 interface to the TD.

Abstract: A method and apparatus to perform persistence tests for a mobile station in a network are described. The apparatus includes a random number generator, a timer module, and a processor coupled to the random number generator and the timer module. A counter for the random number generator configured to count access slots is initialized. One or more random numbers are successively generated, until a value of a generated random number is lower than a first predetermined value. At the same time, the counter is successively incremented based on the number of generated random numbers. When the counter value is higher than or equal to a second predetermined value of successive iterations, or, in the alternative, when the value of the generated random number is lower than the first predetermined value, the mobile station is deactivated for a predetermined number of access slots equal to the counter value. A timer interrupt further runs subsequent to the expiration of the predetermined number of access slots.

Abstract: MIP Home Agent (HA) architectures are described that decompose, e.g., split, packet forwarding control functionality from actual data packet forwarding operations performed by a conventional MIP HA. This places MIP routing control in a node which is distinct from the tunnel end-points which perform packet forwarding operations to direct packets including a mobile's Home Address. Tunneling establishment and control functionality is implemented by what is referred to herein as decomposed HA (DHA) while data packet forwarding and redirection is performed, under the control of the DHA, by a tunneling agent (TA) node. The tunneling agent node serves as the data packet redirection node for a mobile as it moves from one location to another and may be located outside of a firewall used to protect the DHA. Tunnel endpoint nodes (Mobile Nodes and/or Access Nodes) send tunnel packets to the tunnel agent whilst directing control signaling packets to the DHA.
