  • Patent number: 7978683
    Abstract: The method provides for a first network controller, operating according to a first radio technology, to form and send a relay message to a second network controller, operating according to a different, second radio technology. The relay message includes an embedded message for the second network controller. The embedded message may be a transition message requesting transition of a packet switched call for a mobile station handled by the first network controller to a call for the mobile station handled by the second network controller. The method further provides selection of another wireless element for service at a wireless unit, using a current wireless element. A wireless unit receives a message identifying at least one other wireless element, available to the wireless unit and to which a wireless element currently in communication with the wireless unit is also in communication with and the wireless unit selects another wireless element for possible future service based on the message.

  • Patent number: 7352717
    Abstract: A method for performing network control in wireless communication systems and a network entity for performing the same. The method and network entity pool at least one network parameter at the network entity, from at least two active set base transceiver stations and determine a current status of a mobile in the wireless communication system, using the pooled network parameters. The active set base transceiver stations may include a serving base transceiver station and a target base transceiver station. The network parameter may be a confidence metric and/or an error metric for each of a plurality of hypotheses, a power up/power down signal, and/or a measured signal-to-noise ratio and/or energy parameter of a pilot signal from the mobile. The current status of the mobile to be determined may be the mobile's decision to switch to the target base transceiver station transceiver or which base transceiver station transceiver the mobile is currently communication with.

  • Patent number: 7251228
    Abstract: A method for switching cells by a mobile equipment of a communication system. The mobile transmits a signal coded with a spreading code indicating the mobile's intent to switch cells and the coded information also identifies to which cell the mobile wants to switch. The coded information contains channel measurement adjustment information that is continuously transmitted to the cell which is currently serving the mobile. The flow of channel measurement adjustment information is therefore not disturbed by the application of the method of the present invention. Because the coded information identifies the target cell and indicates the mobile's intent to perform a cell switching procedure, the amount of processing done by the cells is significantly reduced thus increasing the likelihood of a successful switching procedure.

  • Patent number: 7200115
    Abstract: In the method, a receiver receives an indication of if the maximum number of sub-packet transmissions for conveying a data packet from a transmitter to the receiver has taken place. If the receiver has not properly received the data packet over a channel when this indication is received, then the receiver sends a non-acknowledgement response that causes the transmitter to re-schedule and re-send the data packet.

  • Patent number: 7200750
    Abstract: A first communication network is used to securely communicate a key that is used for communications over a different network. In one embodiment, a CDMA network is used to securely communicate a key that is used for communications in a data network. The key used in the data network may be used for authentication and/or enciphering or encryption.

  • Patent number: 7171165
    Abstract: A mobile terminal selects a transmission rate for the reverse common signaling channel in response to at least one mobile-terminal-measured metric that is associated with the RF conditions of the channel. The mobile terminal is provided with information, where the information takes the form of at least one threshold level that the one or more measured metrics are compared with, to determine the rate at which at which the mobile terminal should transmit.

  • Patent number: 6654422
    Abstract: A variable length sequence number is used to identify data units in a communication channel. The sequence number associated with the most recent data that has been received successfully and the sequence number expected with the next new data message to be received are examined to determine the minimum size sequence number necessary to unambiguously identify to the transmitter incorrectly received data that must be retransmitted in a later message. The receiver provides the transmitter with the sequence number associated with the last successfully received byte of data and the sequence number associated with the next expected byte of data. The receiver communicates this information to the transmitter using a NAK control message.

  • Publication number: 20030166406
    Abstract: A flexible synchronization message format permits older mobiles as well as newer mobiles to access a wireless communication network. Three types of synchronization messages are time division multiplexed unto the synchronization channel. A first message is interpreted by the newer mobiles and some older mobiles. A second message is interpreted by a second set of older mobiles and a third message is interpreted by a final set of older mobiles. The second and third type of messages are formatted so that they will be ignored by the newer mobiles so that the newer mobiles will not follow instructions associated with older standards and, thereby, not take advantage of options offered under the newer standards. In another embodiment, the frequency with which each of the three messages is transmitted is varied to provide preferential treatment to a particular message type.
