    摘要： A method and apparatus for operating a cellular telephone system that supports performing an inter-system soft handoff is described. A subscriber unit generates a pilot strength measurement report when the pilot channel from a base station is detected. When a base station controller receiving the pilot strength measurement report determines that the base station is part of a second cellular telephone system, a inter-system soft handoff request is generated. An admission control subsystem receives the inter-system soft handoff and either grants or denies the request base on the traffic level with the second cellular telephone system. In a preferred embodiment of the invention, the traffic level is determined based on link load messages received periodically by the admission control subsystem that are generated by an interface port coupled to an interconnect between the first cellular telephone system and the second cellular telephone system. The link load message include peak queue length and average frame rate information.

    摘要： A method and apparatus for performing an inter-system soft handoff is described. In accordance with the present invention, when a subscriber unit crosses from a first cellular system to a second cellular system, a base station controller determines if sufficient network resources are available to conduct a inter-system soft handoff. If so, the base station controller generates a set of signaling messages that cause call processing resource to be allocated and for the call to be processed at the second cellular system. The base station controller then perform data-selection and data-broadcast for the call by transmitting data to the subscriber unit by way of the second cellular system as well as via one or more base stations to which the base station controller is directly coupled. The determination as to whether sufficient network resources are available to conduct the inter-system soft handoff is based on the type of connection that exists between the first cellular system and the second cellular system, the number of inter-system calls being conducted, and the frame offset of the call currently being processed.

    摘要： A method of designing a network results in a network with an efficient addressing scheme which allows for filters to perform a simple logical operation. The process begins by arranging a plurality of nodes connected by a plurality of bi-directional links in a tree topology. Each node is assigned a range of consecutive flow process addresses such that each packet carried in a first direction on one of the bi-directional links has an address within the range A

    摘要： Certain aspects of the present disclosure present methods and apparatus for selecting a power saving mode for a mobile station (MS) in a wireless network. The power saving mode may be selected based on the traffic that is observed at the MS in a predefined duration. Once low overall data traffic is observed, the device may enter a first low power state. If data traffic of a particular type (e.g., not for management or maintenance purposes) is not observed for a predetermined duration, the device may enter a second low power state (deeper than the first low power state).

    摘要： In a mobile device for wireless communication capable of communicating on multiple radio access technologies (RATs), cell selection may be improved by reusing cell measurements for inter-RAT cell selection. This will reduce the number of cell measurements taken and improve mobile device performance. A time threshold may be used to instigate new cell measurement to prevent cell measurement data from being outdated.

    摘要： Handover processes in multi-carrier carrier time division-synchronous code division multiple access (TD-SCDMA) systems include a two-step handover process. When handover of a user equipment is warranted, a hard handover is performed within a source cell of the system from a first frequency to a second frequency. A baton handover is then performed from the second frequency at the source cell to the second frequency at a target cell. In another aspect, a user equipment receives an assignment of an uplink time slot at a target cell that was selected to prevent the uplink time slot from being proximal to a downlink time slot of a source cell. The user equipment then performs the inter-frequency baton handover using the uplink time slot.
