Abstract: A wireless communication network has radio resources for use to support calls over circuit switched (CS) and packet switched (PS) channels. The network uses such radio resources to first support CS calls and thereafter uses the leftover radio resources to support PS calls. The present invention provides method and apparatus that effectively schedule and support incoming CS calls based on frame-offset selection so as to maximize the leftover radio resources that could be used to support PS calls.

Abstract: A wireless communication network includes a base station system that transmits sector congestion information to influence mobile station sector selection processing. In an exemplary embodiment, where at least some of the mobile stations being supported by the network autonomously select the network sector from which they wish to receive forward link packet data transmissions, an exemplary base station influences that sector selection processing by transmitting congestion information on a per sector basis. Complementing that transmission by the network, an exemplary mobile station incorporates consideration of the sector congestion information into its autonomous sector selection processing logic. Thus, where potentially large numbers of mobile stations individually select the “best” sector from a candidate set of sectors, the network can perform load balancing by advertising sector congestion levels, so that mobile stations can choose (or avoid choosing) a given sector based at least in part of the congestion information.

Abstract: A base station inserts an overhead message into a broadcast stream transmitted to a mobile station. To support autonomous soft handoff by the mobile station, the base station inserting the overhead message sends a notification message to one or more of the base stations transmitting the same broadcast stream. The notification message indicates the time when the overhead message will be sent and the duration and/or length of the overhead message. The broadcast channel may be divided into multiple time slots to support mixed flows. Base stations supporting a mobile station in soft handoff can agree on the time slots allocated for a designated broadcast stream.

Abstract: A collaborative focused crawler crawls documents on a network locating documents that match multiple focus topics. The collaborative crawler comprises a fetcher and a focus engine. The fetcher prioritizes which documents to crawl based on a set of rules, obtains documents from the network, and outputs crawled documents to the focus engine. The focus engine determines whether a fetched document is relevant to any of the multiple focus topics. The focus engine determines whether fetched documents are disallowed. If a fetched document is disallowed, the present system may place the URL for that web document in a blacklist, a list of URLs that may not be crawled. URLs may be disallowed if they match a disallowed topic or if they fail a set of rules designed for a web space focus, for example, domain rules, IP address rules, and prefix rules.

Abstract: A reverse link rate control method and apparatus provide first rate control commands as the primary rate control for general, ongoing control of the reverse link rates of one or more mobile stations. These first rate control commands comprise, for example, periodically transmitted common rate control commands that are generated as a function of reverse link loading and are used to control the reverse link rates of mobile stations whose service requirements currently do not require targeted reverse link rate control. The exemplary method and apparatus further provide second rate control commands on an as needed basis, that are sent to targeted ones of the mobile stations to meet the specific Quality-of-Service requirements at individual mobile stations, or groups of mobile stations. Supplemental rate control channels can be assigned and released dynamically to targeted mobile stations to provide supplemental rate control on an as-needed basis.

Abstract: Provisioning and access control for communication nodes involves assigning identifiers to sets of nodes where the identifiers may be used to control access to restricted access nodes that provide certain services only to certain defined sets of nodes. In some aspects provisioning a node may involve providing a unique identifier for sets of one or more nodes such as restricted access points and access terminals that are authorized to receive service from the restricted access points. Access control may be provided by operation of a restricted access point and/or a network node. In some aspects, provisioning a node involves providing a preferred roaming list for the node. In some aspects, a node may be provisioned with a preferred roaming list through the use of a bootstrap beacon.

Abstract: In a handover operation an access terminal is handed over from a source access point to a target access point. To facilitate efficient identification of a target access point, a handover operation may be initiated by the target access point. A candidate frequency search also may be invoked to confirm that an access terminal identified by a target access point for a handover is in the vicinity of the target access point. A source access point may verify whether an access terminal is in a vicinity of a target access point to determine whether to perform a handover operation. A source access point may handle potential ambiguity between several target access points by sending handover commands to each of these target access points. An access terminal also may assist in the determination of whether to perform a handover operation.

Abstract: Aspects disclosed herein relate to effectively handling failure and retry mechanisms during pre-registration for an eHRPD optimized handover. In one example, a UE may be equipped to detect one or more instances of failure during a pre-registration procedure as part of an optimized handover process. The UE may further be equipped to perform one or more pre-registration retry processes based on the detected one or more instances of failure. In one aspect, the one or more instances of failure may include any combination of a permanent LTE connection failure, a temporary LTE connection failure, a session negotiation failure, a virtual connection failure when bringing up a data call, a link control protocol (LCP) failure, etc.

Abstract: Aspects disclosed herein relate to enabling fallback to a second data service based on whether one or more fallback conditions are present before or during establishing a data context with a first data service. In one example, a UE may be configured to determine whether one or more fallback conditions are present before or during establishing a data session with a first data service. The UE may be further configured to prohibit further attempts to establish a data context to access the first data service based on the determination of the presence of at least one of the one or more fallback conditions. Some aspects disclosed herein relate to enabling fallback to a HRPD data service based on whether one or more fallback conditions are present before or during establishing a data context with an eHRPD data service.

Abstract: Aspects are described for redirecting wireless terminals between wireless networks. In a first embodiment, a coverage quality of user equipment within a first wireless network is monitored. Multiple candidate frequencies are then ascertained in response to the coverage quality to facilitate a communication between the user equipment and a second wireless network. The candidate frequencies are then communicated to the user equipment. In another embodiment, an indication of a plurality of candidate frequencies is received, and a failure in performing a handover from a first wireless network to a second wireless network is detected. For this embodiment, the handover is attempted via a primary frequency. An alternative frequency is then selected from the plurality of candidate frequencies in response to the failure, and a communication with the second wireless network is established via the alternative frequency.
