Patent number: 7515555Abstract: The present invention addresses a problem that switching antennas along with an unexpected variation of a received electrical field strength brings about a loss over a long period of data transmission. According to a wireless LAN transceiver in which the present invention is implemented, when a data throughput attained by an application layer poses no problem, switching antennas is disabled. Consequently, the data throughput can be kept satisfactory. Namely, since whether the antennas are switched is not determined with an unexpected variation of an RSSI signal or an error rate in a lower layer, unnecessary switching of the antennas can be prevented. A loss derived from the switching of the antennas can be minimized over a long period of time.Type: GrantFiled: November 30, 2004Date of Patent: April 7, 2009Assignee: Buffalo Inc.Inventor: Takashi Ishidoshiro

Patent number: 7471950Abstract: Base station controlled vertical handoff is disclosed. When a hybrid access terminal is operating under a first air interface protocol (e.g., IS-2000), in a mode (e.g., active) in which the terminal does not search for the presence of wireless service under a second air interface protocol (e.g., IS-856), the terminal sends a request to a base station seeking to hand off to a wireless coverage area under the protocol. The base station then determines (e.g., by reference to the PN offset specified in the request) that the target coverage area additionally provides service under the second protocol. Responsively, the base station causes the terminal to transition to a second mode (e.g., dormant) in which the terminal does search for the presence of service under the second protocol. The terminal may thereby discover the presence of service under the second protocol and may hand off to operate under the second protocol.Type: GrantFiled: January 27, 2005Date of Patent: December 30, 2008Assignee: Sprint Spectrum L.P.Inventors: Dae-Sik Oh, Leo R.

Patent number: 7388855Abstract: A method and a packet data network for providing broadcast/multicast services (BCMCS) to a mobile terminal (MT). The method receives at a Dynamic Host Configuration Protocol (DHCP) server from the MT, for requesting an IP address of a primary BCMCS controller that serves the packet data network. The method retrieves the IP address of the primary BCMCS controller and responds to the MT with a response message from the DHCP server to the MT, the response message includes the IP address of the primary BCMCS controller. Next, the MT uses the IP address of the primary BCMCS controller and sends a Hyper Text Transfer Protocol (HTTP) request message from the MT to the primary BCMCS controller for requesting BCMCS services, the HTTP request message including a location information and an access type indicator of the MT. Afterwards, a list of available BCMCS programs is provided to the MT.Type: GrantFiled: November 15, 2004Date of Patent: June 17, 2008Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventor: Lila Madour

Patent number: 7327716Abstract: A mobile station transmits sub-packets at a specified transmission rate or an autonomous transmission rate based on a PERSISTENCE bit. The mobile station increments, decrements, or does not change the transmission rate when the PERSISTENCE bit is a second logic state and a rate control bit (RCB) value is a first, a second, or a third value. Another embodiment of the present invention includes an ALL_ACID_IND bit that instructs the mobile station to adjust the specified transmission rate for either a single H-ARQ channel or for all H-ARQ channels. In an alternate embodiment, the mobile station uses the RCB in conjunction with a NAK to adjust a transmission-to-pilot ratio. After the NAK, the mobile station monitors the RCB value to increase the transmission rate, decrease the transmission rate, or not to change the transmission rate of subsequent sub-packets of the same data packet.Type: GrantFiled: March 5, 2004Date of Patent: February 5, 2008Assignee: Nortel Networks LimitedInventors: Mo-Han Fong, Jun Li, Ashvin H.
