    摘要： Methods and systems for providing random access to structured media content are described. The described methods and systems implement one or more of an importance evaluator module, a priority evaluator module, and a preemptive loader module. The importance evaluator assigns importance values to different portions of a structured media content file. The importance values are used to determine whether to remove individual portions of the structured media content file from a client cache file to make room for other more important file portions. The priority evaluator assigns priority values to different portions of a structured media content file. The priority values are used to determine an order in which the portions are to be provided from a server to a client. The preemptive loader preemptively facilitates provision of one or more portions of a structured media content file to a client, without the client specifically requesting so.

    摘要： Methods and systems for providing random access of structured media content are described. One aspect provides a novel file structure or “Vfile”, and method of using the same, for organizing and managing portions of a structured media content file that are or can be downloaded from a content provider such as a multimedia content server. The Vfile is configured to emulate a server file structure that a server uses to store structured media content files. The Vfile is established at a client location when a client accesses a structured media content file and is used to buffer and cache structured media content file portions. In addition, the Vfile includes one or more media management tags. The tags are used by the client to manage a cache of structured media content file portions that are downloaded from the server.

    摘要： Methods and systems for providing random access of structured media content are described. One aspect provides a novel file structure or “Vfile”, and method of using the same, for organizing and managing portions of a structured media content file that are or can be downloaded from a content provider such as a multimedia content server. The Vfile is configured to emulate a server file structure that a server uses to store structured media content files. The Vfile is established at a client location when a client accesses a structured media content file and is used to buffer and cache structured media content file portions. In addition to having an infrastructure that emulates the server's file structure, the Vfile includes one or more media management tags. The tags are used by the client to manage a cache of structured media content file portions that are downloaded from the server. Exemplary tags include, but are not limited to (1) a validity tag that indicates whether a particular portion of a structured media content file is available in the Vfile cache, (2) a hit count tag that gives an indication of how many times a particular portion has been accessed, (3) an importance tag that gives a weight to the hit count and determines how long the portion can stay in cache, and (4) a lock tag that indicates whether or not to lock selected structured media content file portions in the Vfile. Cache management strategies make use of the management tags to ensure that relevant portions of the media file are maintained by the client for as long as they are needed. Those file portions that are needed, but which are not present in the Vfile, can be streamed to the client by the server while those file portions that are present are used to render a view for the user.

    摘要： Systems, methods, and apparatus are described that employ specially designed interference patterns to build an in-band side channel without degrading the effective throughput of the main channel. A first device (100) includes a control component (130) that generates control information and an interference component (140) that transmits the control information (450) through emission of patterned interference data concurrently while other users are transmitting other data (420). A second device (300) receives the patterned interference data and the other data via a single antenna (350) and decodes the patterned interference data to extract the control data (450). The first device (100) transmits the other data (420) on a side channel (440) that resides in the same spectrum as the main channel (410) in which the other data (420) is emitted. The first device (100) encodes the interference patterns such that the control data (450) can be safely transmitted and extracted without effecting other data transmission. In one aspect, devices (100, 200, 300) can employ a dynamic cooperation multi-access channel (DC-MAC) protocol (1510) to schedule transmission of the other data (420) on the main channel (410), and to employ the side channel (440) for control and coordination.

    摘要： A method and device for detaching a user equipment (UE) are disclosed in the present invention. The UE is registered with a mobility management entity (MME) in a packet switched (PS) network and a mobile switching center (MSC) in a circuit switched (CS) network. When the UE needs to detach from the PS network, the MSC receives a Detach Request with a Detach Type indicating the detaching from the PS network only; after receiving the Detach Request, the MSC deletes the context of the PS core network entity and clears the connection between the MSC and the MME. An MME for performing UE detachment is also disclosed in the present invention. The present invention helps reduce the time delay during the subsequent handover and quickly provide users with communications services, so as to improve user's experience and meet the carriers' requirements.
