  • Publication number: 20100272124
    Abstract: Method and System for Utilization of an Outer Decoder in a Broadcast Services Communication System is described. Information to be transmitted is provided to a systematic portion of a plurality of transmit buffers and encoded by an outer decoder communicatively coupled to the transmit buffer. The resulting redundant bits are provided to a parity portion of each transmit buffer. The content of the transmit buffers, is multiplexed and encoded by an inner decoder to improve protection by adding redundancy. The receiving station recovers the transmitted information by an inverse process. Because a decoding complexity depends on the size of a systematic portion of the transmit buffer, reasoned compromise between a systematic portion size and number of transmit buffers yields decreased decoding complexity.

  • Publication number: 20100203865
    Abstract: Systems and methodologies are described that facilitate managing access control to Closed Subscriber Groups (CSGs) in a wireless communication environment. A user equipment (UE) can store an operator CSG list, which can be read only and controlled by an operator. Further, the operator CSG list can lack synchronization to a CSG subscription for the UE retained in the network. Thus, upon selecting to access a CSG cell associated with a CSG with a corresponding CSG Identifier (ID) included in the operator CSG list of the UE, a reject message that indicates that the UE lacks authorization for the CSG can be received. Moreover, the CSG ID can be stored as a forbidden CSG ID of the UE in a set of forbidden CSG IDs in response to receipt of the reject message when the CSG ID is included in the operator CSG list.

  • Publication number: 20100202391
    Abstract: Systems and methodologies are described that facilitate communicating between access points using the same air interface as for serving wireless devices. Access points can communicate with one another over the air interface to exchange interference management messages related to negotiating and/or allocating resources among the access points or other messages. In addition, access points can prepare served wireless devices for time periods where the access points communicate with disparate access points over the air interface to mitigate confusion or radio link failure detection by the served wireless devices.

  • Publication number: 20100197285
    Abstract: Problems caused by interaction between paging optimization and synchronizing CSG information are mitigated by setting a network indication indicating, for example, that a subscriber is no longer a member of a CSG, but the network has not yet received confirmation that an access terminal associated with the subscriber has been informed of this. A timer-based scheme may be employed for removing a CSG ID from the subscriber information for a subscriber once it is determined that the subscriber is no longer a member of the CSG. In addition, a temporary member of a CSG may determine whether it is still a member of a CSG upon expiration of a CSG timer. Also, the frequency with which an access terminal registers may be changed based on various criteria. Furthermore, an allowed CSG list may be selectively included in a page message depending on the destination of the page message.

  • Publication number: 20100197239
    Abstract: Providing for automated wireless network signal analysis by mobile devices as a function of their geographic locations is described herein. By way of example, a wireless network can transmit a set of geographic data defining a geographic region to a mobile device. The mobile device can compare its current location to the geographic region, and begin measuring downlink signals, or recording such measurements when within the geographic region, and terminate the recording when the mobile device leaves the geographic region. Recorded measurements can be subsequently uploaded to the wireless network for analysis. In some aspects, the mobile device can refrain from uploading the measurements until within a defined reporting region. By providing mobile device network analysis triggered on device geographic location, analysis data that is well tailored to a particular problem area can be obtained, increasing quality of the analysis data and significantly reducing cost of acquiring such data.

  • Publication number: 20100177737
    Abstract: Systems and methodologies are described that facilitate fetching a native security context between network nodes in a core network after an inter-system handover of a mobile device. For instance, a mobility message that is integrity protected by a security context (e.g., the native security context, a mapped security context, . . . ) can be obtained at a network node from the mobile device. Further, the network node can send a request to a disparate network node within a core network. The request can include information that can be used by the disparate network node to establish that the mobile device is authenticated. Moreover, the native security context can be received from the disparate network node in response to the request. Accordingly, the native security context need not be recreated between the network node and the mobile device.

  • Publication number: 20100173626
    Abstract: Handover parameter settings are automatically adapted in access points in a system to improve handover performance. Reactive detection techniques are employed for identifying different types of handover-related failures and adapting handover parameters based on this detection. Messaging schemes are also employed for providing handover-related information to access points. Proactive detection techniques also may be used for identifying conditions that may lead to handover-related failures and then adapting handover parameters in an attempt to prevent such handover-related failures. Ping-ponging may be mitigated by adapting handover parameters based on analysis of access terminal visited cell history acquired by access points in the system. In addition, configurable parameters (e.g., timer values) may be used to detect handover-related failures.

  • Publication number: 20100135206
    Abstract: Radio access interworking technologies allow a target network to notify a source network that a mobile device has moved from source network to target network, wherein mobile device does not need to perform notification to source network. Further, source network can provide a first subset of overhead information to mobile device and, after moving to target network, mobile device can receive a second subset of overhead information from target network. Further, mobile device can perform prehashing prior to moving to target network based on a channel list received from source network.

  • Publication number: 20100124172
    Abstract: The number of handover-related failures that occur in a communication system may be reduced by taking target access point conditions into account when declaring radio link failure and/or by delaying certain handover operations. In some aspects, criteria for radio link failure detection and access terminal-controlled mobility may take into account access point parameters related to neighboring cells that may be available as mobility targets. For example, filtering mechanisms for detecting radio link failure based on radio layer problem reports may also take into account the availability of various neighbor access points and their measured signal strengths. In addition, a handover command may be sent earlier than in conventional systems (e.g., the handover command may be sent even though the target access point is weaker than the source access point) and include an indication that instructs the access terminal to delay handover until a specified condition is met.

  • Publication number: 20100124173
    Abstract: A communication node determines that radio link failure occurred during connected state mobility of an access terminal and reports the radio link failure to another communication node. For example, a target access point may determine that radio link failure occurred during handover of an access terminal and send a radio link failure report message to the access point that was previously serving the access terminal or to some other node (e.g., a network node). In the first case, the serving access point may adjust mobility parameters based on this radio link failure information and, optionally, other reported radio link failure information. In the second case, the other node may send a radio link failure report message to the serving access point, or the other node may adjust mobility parameters based on this radio link failure information (and, optionally, other reported radio link failure information) and send the adjusted mobility parameters to the serving access point.
