    摘要: An improved arrangement is described for signaling enhanced capabilities of a wireless data communication system to a dual-mode wireless handset seeking access to such capabilities and normally operating in a first (non-enhanced) mode. The arrangement, which is especially advantageous for ascertaining operating mode capabilities of a new cellsite to which the handset is being handed off from an existing cellsite, includes a separate capabilities server that is associated with the system and contains a data base populated with information indicative of such capabilities. The handset generates a suitable query message which is transmitted to the data base in the first mode after the handoff to retrieve the capability information for the new cellsite location. The handset is switched from the first mode to the second (enhanced) mode for post-handoff operation if the retrieved capability information indicates that the new cellsite is capable of operation in the enhanced mode.

    摘要: A method and a wireless transmit/receive unit perform a handoff to a target base station having enhanced capabilities. A dual mode manager triggers a capabilities query for information regarding enhanced capability of the target base station, wherein the enhanced capability includes transmission in accordance with a high speed data mode. A generator sends the query to a server connected to the Internet via a first base station not having enhanced capability. The dual mode manager receives from the server via the first base station information regarding the enhanced capability. A handoff to the target base station is initiated by the dual mode manager on a condition that the received information indicates that the target base station has enhanced capability. The dual mode manager deactivates a first mode of operation for communication with the first base station and activates the high speed data mode for communication with the target base station.

    摘要: A system and method are provided for allocating wireless channels in a base station processor to messages sent between a subscriber and the base station processor in a wireless network. A latency period is determined corresponding to a return message to be received from a responsive node in response to an outgoing message sent from a sender via the base station processor. A latency manager in the base station processor computes the latency period and stores the latency period in an allocation table. A scheduler schedules a channel to be available at the end of the latency period indicated in the allocation table. At the end of the latency period, the return message is received and the scheduler allocates a channel as defined in the allocation table. The scheduled channel is used to transmit the message to or from the corresponding subscriber.

    摘要: A packet data system such as a TCP/IP network transmits packets containing a variety of data types along links in the network. Packets are transmitted in a stream between nodes interconnected by the links connections which conform to a transport layer protocol such as TCP, UDP, and RSTP, and includes wireless links, which transmit packets using a radio frequency (RF) medium. Typical protocols, however, are usually developed to optimize throughput and minimize data error and loss over wired links, and do not lend themselves well to a wireless link. By examining the data in a packet, performance characteristics such as a port number are determined. The performance characteristics indicate the application type, and therefore, the data type, of the packets carried on the connection. Since certain data types, such as streaming audio and video, are more loss tolerant, determination of the data type is used to compute link control parameters for the wireless link which that are optimal to the type of data being transmitted over the link.

    摘要: In an illustrative embodiment of the present invention, a channel is allocated to carry messages from each of multiple subscriber units to a base station. Selected messages generated by a subscriber unit that would otherwise be transmitted over an assigned reverse link traffic channel are instead encoded and transmitted to the base station over a shared reverse link channel. Preferably, the shared reverse link channel is time-slotted and each subscriber unit transmits information to the base station in an assigned time slot so that the base station receiving the messages can identify from which subscriber unit a message is sent. Certain bits in a time slot of the shared channel as set by a subscriber unit can be used to communicate a particular message to the base station. For instance, a single bit that is transmitted in a time slot can be encoded to transmit a substitute message from one of the multiple subscriber units to a base station, where the setting of the bit itself indicates a message type.
