  • Patent number: 8699452
    Abstract: Techniques for congestion control are disclosed. In an embodiment, a base station allocates a shared resource using a combination of zero or more individual grants and zero or more common grants, and generates a multi-valued busy signal in response to loading conditions that exceed a pre-determined level. In another embodiment, a subset of transmitting mobile stations reduce their transmission rate in response to a multi-valued busy signal. The subset may include autonomous transmission, commonly granted transmission, individually granted transmission, or any combination thereof. In various embodiments, rate adjustment may be probabilistic or deterministic. In an embodiment, a rate table is deployed, and a mobile station decreases or increases the transmission rate from one rate in the table to a lower or higher rate in the table, respectively, in response to the busy signal. Various other aspects provide efficient congestion control, avoiding excessive interference and increasing capacity.

  • Patent number: 8320328
    Abstract: Channel dependent credit accumulation for determining a mobile handover is provided herein. In some aspects, a characteristic(s) of a source channel(s) serving a mobile device and of one or more target channels can be evaluated. Magnitudes of the evaluated characteristics can be utilized to generate handover credits associated with the target channel(s) (e.g., based on some function of a difference in the magnitudes). If a concurrent number of credits associated with a target channel equals or rises above one or more threshold levels, a mobile device can initiate a handover. As described, disparity in source and target channel quality, signal strength, etc., can be determined to increase probability of a handover based on channel degradation over one or more time intervals.

  • Patent number: 8300619
    Abstract: A system and method for enabling scheduled data messages to be transmitted within a communication system on a controlled access packet data channel. When a scheduled data message is to be transmitted, a mobile device generates the data message, appends a predetermined type of header to the data message, and passes the data message to a communication unit. The header comprises an hour field, a minute field, and a slot field indicative of a specific time when the data message is to be transmitted on the controlled access packet data channel. After receiving a data message from the mobile device, the communication unit parses the received data message to determine whether the received data message should be processed as a scheduled data message on the controlled access packet data channel, and transmits the data message to a fixed network at a specific time based on the hour, minute, and slot fields in the header.

  • Patent number: 8265100
    Abstract: A method for start-up of a network, including a number of nodes, which are connected via channels. The nodes exchange information in the form of messages via the channels. The transition phase of a synchronizing node from its initial phase to a synchronized phase is separated in a first integration phase and a second subsequent cold-start phase. A synchronizing node in the integration phase listens to messages being sent from nodes in the synchronized phase and only reacts to an integration message (i-frame) if the integration message is a valid message. Furthermore, a synchronizing node, wherein integration of the synchronizing node to a set of already synchronized nodes was not successful after a specifiable period, changes into the cold-start phase, in which a cold-start procedure of the node is extracted, wherein in the cold-start phase the node does not react to integration messages of a node in the synchronized phase.

  • Patent number: 8243656
    Abstract: What is disclosed is a wireless access system. The wireless access system includes a wireless access control system configured to maintain an available pool of Media Access Control Identifiers (MAC IDs) for subsequent use by a base station, remove a portion of the MAC IDs from the available pool, and use the portion of the MAC IDs for wireless communications between a wireless transceiver of the base station and a plurality of user devices. The wireless access control system is configured to determine that the available pool of the MAC IDs is insufficient, and in response, select a set of the user devices based on at least wireless signal strength. The wireless transceiver of the base station is configured to instruct the selected set of the user devices to not use the base station for the wireless communication, and in response, the wireless access control system is configured to return ones of the MAC IDs used by the selected set of the user devices to the available pool.

  • Patent number: 8233418
    Abstract: Embodiments of a mobile station and method for dynamically changing a sleep cycle are generally described herein. The mobile station is configured to dynamically switch a sleep cycle without deactivating a current power savings class (PSC). In some embodiments, the mobile station may generate a dynamic sleep-cycle switching message to request a change in the sleep cycle of the mobile station when changes in downlink traffic are detected. The dynamic sleep-cycle switching message may indicate either one of a plurality of predefined sleep cycles or may indicate parameters defining a new sleep cycle. This may allow the sleep cycle of the currently active PSC to be changed without deactivation.

  • Patent number: 8228855
    Abstract: Systems and methodologies are described that facilitate reporting an uplink power headroom (UPH) during an E-DCH transmission in a CELL_FACH state. For a E-DCH transmission, a reduced measurement period can be utilized in order to report a UPH measurement. In particular, the reduced measurement period can be less than 100 milliseconds. The UPH measurement can be communicated based upon receipt of AICH/E-AICH and transmission of DPCCH for a configurable number of radio frames. The UPH measurement can be based upon the transmitted power prior to actual data transmission. Additionally, the UPH measurement can be included within scheduling information portion of a MAC header.
