Patent number: 9025466Abstract: A transmission initiation interval timing structure is used in combination with a lower layer timing structure, e.g., physical layer timing structure. A device selects a subset of packet transmission initiation intervals and then limits initiation of packet transmission to those intervals thereby reducing the potential for collisions. Packet transmission may occur outside the initiation interval in which the transmission is initiated. In some embodiments, packet transmission length is intentionally limited to sizes which can be transmitted in a fraction of the amount of time the physical layer allows a single device to continuously transmit, e.g., in an amount of time which is equal to or less than the duration of a packet transmission initiation interval. This increases the probability that multiple devices will be able to successfully transmit small packets at short intervals on a regular basis even when carrier sensing techniques are used.Type: GrantFiled: July 5, 2012Date of Patent: May 5, 2015Assignee: QUALCOMM IncorporatedInventors: Ying Wang, Sundar Subramanian, Xinzhou Wu, Junyi Li, Thomas J.

Patent number: 9014014Abstract: Methods and systems for operating a physical layer device (“PHY”) in an Ethernet network include methods and systems for detecting active link partners and for selecting a mode of operation based on detected active link partners. The PHY monitors fiber link media and copper link media for active link partners. The PHY selects a mode of operation according to detected active link partners. For example, a copper mode of operation is selected, preferably through logic circuitry, when an active copper link partner is detected and an active fiber link partner is not detected. Similarly, a fiber mode of operation is selected, preferably through logic circuitry, when an active fiber link partner is detected and an active copper link partner is not detected. The PHY interfaces with the active copper link partner when the copper mode of operation is selected. Similarly, the PHY interfaces with the active fiber link partner when the fiber mode of operation is selected.Type: GrantFiled: September 21, 2007Date of Patent: April 21, 2015Assignee: Broadcom CorporationInventor: Gary S.

Patent number: 8989098Abstract: A method for gracefully extending the range and/or capacity of voice communication systems is disclosed. The method involves the persistent storage of voice media on a communication device. When the usable bit rate on the network is poor and below that necessary for conducting a live conversation, voice media is transmitted and received by the communication device at the available usable bit rate on the network.

Patent number: 8976679Abstract: The present solution relates to enabling improved performance for a user equipment UE (205) in a communication network (200). A network node (210) detects (301, 401) that wireless performance between the UE (205) and a base station (201) is poor. Then, it identifies (302,402) a location of the UE (205) where the poor performance is detected, obtains (303,403) an identity associated with the UE (205), obtains (304,404) an address associated with the UE (205) and identifies (305,405) that the location of the UE (205) is residential and that the address corresponds to the location. The node (210) searches (306,406) for a wireline connection (219) located within a distance from the UE (205). The node (210) establishes (307,407) whether the performance for the UE (205) would be improved by providing services from a core network (209) to the UE (205) via the wireline connection (219) using the home base station (215).Type: GrantFiled: June 9, 2010Date of Patent: March 10, 2015Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Bogdan Timus, Åsa Bertze, Kimmo Hiltunen
