Patent number: 7322041Abstract: A communication system having a wireless trunk for connecting multiple phone lines over wireless communication links to a cellular network comprises a central telephone switch, such as a private branch exchange or key system, connected through one or more trunk lines to a wireless access communication unit. The wireless access communication unit preferably comprises a separate subscriber interface for each trunk line from the central telephone switch. The wireless access communication unit collects data from each of the subscriber interfaces, formats the data into a format compatible with an over-the-air protocol, and transmits the information over one or more wireless channels to a cellular base station. The wireless access communication unit thereby connects calls received from the central telephone switch's trunk lines over a wireless trunk to a network.Type: GrantFiled: July 24, 2002Date of Patent: January 22, 2008Assignee: Intel CorporationInventors: Izzet M. Bilgic, Narayan P. Menon

Patent number: 6751456Abstract: A computer program for a user in a wireless communication system to communicate on the system. The communication protocol embodied in the computer program enables the user to acquire a channel on the base station in the system and register with a base station on the system. The communication protocol embodied in the computer program also enables the user to place and receive calls on the communication system. The communication protocol embodied in the computer program also provides the user a handover procedure for handing over its call to another base station in the system. The computer program is comprised of a main controller task and various other tasks, also called subtasks, which are activated by the main controller task. These subtasks are each designed to perform a protocol function for the user on the communication system.Type: GrantFiled: March 27, 2001Date of Patent: June 15, 2004Assignee: Intel CorporationInventor: Izzet M.

Patent number: 6477382Abstract: A system and method including a flexible paging protocol which adjusts the allocation of resources for paging in response to the amount of actual paging traffic, by increasing resources for paging when paging traffic is heavy and decreasing them when paging traffic is light. A base station transmits a paging packet message over a paging broadcast channel containing a set of paging messages and a next page pointer. The next page pointer identifies when the next set of paging packet message will be transmitted. A user station monitoring the paging channel receives the next page pointer, and, if not being paged, goes to sleep until the next paging packet message is due. When paging traffic is light, paging messages are sent infrequently, freeing up base station resources and allowing the user station to remain asleep longer. When paging traffic is heavy, paging messages are sent more frequently, ensuring rapid response to the pages and reducing the probability of a missed call.Type: GrantFiled: June 12, 2000Date of Patent: November 5, 2002Assignee: Intel CorporationInventors: Carl Mansfield, Izzet M. Bilgic, Benjamin K. Gibbs, Sherman L. Gavette

Publication number: 20020048268Abstract: A telecommunications network supporting wireless access to one or more public packet data networks, including, but not limited to, the Internet, and to one or more public switched circuit networks, for example, but not limited to, the Public Switched Telephone Network (PSTN). A voice access unit, for example, a telephone, may be connected to a Customer Premise Radio Unit (CPRU) via a wireline interface. The CPRU provides the voice access unit over-the-air, i.e., radio, access to one or more public switched circuit networks. A computing device, for example, a personal computer, may also, or in the alternative, be connected to a CPRU via a wireline interface. The CPRU provides the personal computer over-the-air access to one or more public packet data networks. A facsimile device may also, or in the alternative, be connected to a CPRU via-a wireline interface. The CPRU provides the facsimile device over-the-air access to one or more public switched circuit networks.Type: ApplicationFiled: May 15, 2001Publication date: April 25, 2002Applicant: OPUSWAVE NETWORKS, INC.Inventors: Narayan P.

Publication number: 20010043572Abstract: A virtual FDD base station comprises two base station sub-units each of which comprise a base station transmitter and a base station receiver. The first base station sub-unit transmits base-to-user messages to user stations only during a first half of a repeating time frame, and receives user-to-base messages from the user stations only during a second half of the time frame. The second base station sub-unit is preferably collocated with the first base station sub-unit and synchronized thereto, and transmits base-to-user messages to user stations only during half of the time frame, while receiving user-to-base messages from the user stations only during the other half of the time frame. Duplex communication channels are preferably defined by correlating a base transmit time slot with a user transmit time slot, which are separated by a sufficient amount of time to allow transmit/receive switching by a user station.Type: ApplicationFiled: September 24, 1998Publication date: November 22, 2001Inventors: IZZET M. BILGIC, SHERMAN GAVETTE, STEVE HOWSER

Patent number: 6301249Abstract: A method of transmission error control includes transmitting at least one frame of packet data to a receiving entity during each of a plurality of time frames, and receiving a plurality of responsive messages from the receiving entity. Each of the responsive messages identifies frames of data successfully received during a current time frame and during prior time frames. The method also includes retransmitting each of the frames of data that the responsive message does not indicate as successfully received.Type: GrantFiled: August 4, 1998Date of Patent: October 9, 2001Assignee: Opuswave Networks, IncInventors: Carl Mansfield, Izzet M.
