  • Patent number: 8184592
    Abstract: A method, medium, and system for reserving resources in a mobile network. A mobile node reports a start of a handover to a present access router if the handover of the mobile node occurs, and the previous access router transmits specified session information to a candidate access router that has a possibility handling the mobile node's handover. A candidate crossover router, which performs a resource reservation work on a new path and a resource release on the previous path, is searched, and a localized resource reservation is established by exchanging a specified resource reservation message before the handover is completed if the candidate crossover router is determined. Accordingly, duplication of resources can be prevented, and a prompt resource reservation can be achieved during the handover.

  • Patent number: 8169999
    Abstract: Aspects of a method and system for preserving content timing across femtocell interfaces via timestamp insertion are provided. In this regard, a femtocell may receive a first time-stamped packet via a first interface and transcode the time-stamped packet. The femtocell may buffer the transcoded packet based on a time-stamp recovered from the packet and may transmit the buffered transcoded packet via a second interface. One of the first interface and the second interface may utilize the Internet Protocol. One of the first interface and the second interface may be a non-cellular interface and the other interface may be a cellular interface. The femtocell may be operable to generate a timestamp corresponding to a time instant at which a time-stamped packet arrived via the first interface or the second interface. The timestamp may be referenced to a clock within a cellular enabled communication devices communicatively coupled to the femtocell.

  • Patent number: 8170067
    Abstract: A system includes a first integrated circuit device and a second integrated circuit device. The first device transmits a data sequence to the second integrated circuit device, and the second device samples the data sequence to produce receiver data. The second device then transmits the receiver data back to the first device. Within the first integrated circuit device, a comparison between the data sequence and the receiver data is performed, and based on the comparison, the first device generates information representative of a calibrated timing offset. The first device uses the information representative of the calibrated timing offset to adjust timing associated with transferring write data from the first integrated circuit to the second integrated circuit.

  • Patent number: 8169960
    Abstract: Methods and apparatus for communicating and utilizing persistent allocation of uplink resources are described herein. A base station can allocate persistent uplink resources to a client station, such that the resource allocation remains active for future uplink frames without the client station repeating a request for uplink resources or the base station expressly communicating the uplink resource allocation. A client station can request a persistent uplink resource allocation when wireless channel conditions are fairly consistent and not varying and the required uplink resources are predictably periodic and fixed in size. The base station can verify that the uplink resource request meets the criteria for persistent allocation and can allocate persistent uplink resources in a dedicated information element of an uplink resource map that is transmitted to the user. The resources allocated remain allocated to the client station in each frame satisfying a predetermined periodicity until deallocated.

  • Patent number: 8165069
    Abstract: The present invention relates to a fast uplink ranging system and method in a mobile communication system. According to the present invention, a fast uplink ranging system transmits two pairs of ranging codes having the same value at locations spaced by half of FFT pointers. The fast uplink ranging system calculates a correlation value using the received two pairs of ranging codes. An order in which complex exponential twiddle factors for removing complex exponential terms corresponding to a time delay are searched is determined using the correlation value. Therefore, it is possible to reduce a time required for searching a timing error of a terminal using non-periodic symmetry of complex exponential twiddle factors corresponding to the timing error, compared with a known method of searching a complex exponential twiddle factor.

  • Patent number: 8165175
    Abstract: Disclosed is a gap support measuring method which performs autonomous gap allocation without lowering the data transfer rate or the throughput. ST301 acquires various kinds of parameters decided by a network so as to execute a gap support measurement task. ST302 checks the current time and starts the gap support measurement task when the current time has become Ts. ST303 judges whether CQI measured by a terminal is lower than a threshold value. ST304 judges whether the threshold value should be updated. ST306 decides the gap length according to the remaining gap length and the remaining time and performs measurement within the gap. ST307 judges whether the measurement is complete. ST308 checks whether the total of the gaps exceed the entire gap length Tg.
