    摘要: Techniques for managing the load of an access channel in a wireless communication system are described. In an aspect, the load of the access channel may be controlled by having each terminal regulates its use of the access channel (e.g., its rate of system access) based on a rate control algorithm (e.g., token bucket). The rate control algorithm may maintain information on past activities of a terminal and may regulate the use of the access channel by the terminal based on its past activities in order to control the access channel load and achieve fairness. The system may determine at least one parameter value for the rate control algorithm based on load conditions and may broadcast the at least one parameter value to terminals. Each terminal may regulate its use of the access channel based on the at least one parameter value received from the system.

    摘要: In some aspect restricted access nodes are assigned to a designated common channel while access terminals that are in active communication with a macro access node may selectively be assigned to the designated channel. In some aspect an access terminal associated with macro access node may perform a handoff to a different carrier when the access terminal is in the vicinity of a coverage area of a restricted access node. In some aspect an access terminal associated with a macro access node may perform a handoff to a different carrier based on location information. In some aspect access to a restricted access node is controlled based on policy and/or based on operation of an access terminal associated with the restricted access node.

    摘要: A method and apparatus for resolving ambiguity in reception of multiple retransmitted frames includes ascertaining for each data frame received from a transmitter whether the frame is a retransmitted frame. If the frame is a retransmitted frame, the frame may be stored in a resequencing buffer. If an abort timer associated with the second round of retransmission has been set for the retransmitted frame, an associated negative-acknowledgment-list (NAK-list) entry is not removed from a NAK list until the abort timer has expired. If the abort timer has not been set for the retransmitted frame, the associated NAK-list entry is removed from the NAK list. The method and apparatus may reside in a transport function in which a transmitter sends data frames to a receiver in accordance with the Radio Link Protocol interface. The transport function may reside in, e.g., a data-capable cellular or satellite-based base station and subscriber unit.

    摘要: A high data rate system capable of inter-frequency handoffs with little or no interruption in data service. The access network sends data from the first sector to the access terminal at the first frequency. The access terminal measures a parameter of a signal received at the access terminal from the second sector at the second frequency, wherein a pre-active set of the access terminal includes the second sector, and wherein an active set of the access terminal consists of one or more sectors operating in the first frequency. The access terminal then sends a data source control message corresponding to the second sector to the access network, after which the access terminal switches the pre-active set and the active set.

    摘要: A method and apparatus for requesting PPP instances from a packet data services network includes a mobile station configured to send an origination message to a packet data service node (PDSN) at which it has arrived upon leaving the vicinity of another PDSN. The message informs the new PDSN of the new location of the mobile station and indicates both the number of dormant PPP instances associated with the mobile station and a service reference identifier for each such PPP instance. A flag within the message may be used to indicate whether the PPP instances are dormant (i.e., whether the mobile station is engaged in a call).

    摘要: An improved channel structure for use in communication systems is disclosed. The channel structure utilizes two sets of physical channels, one for the forward link and another for the reverse link. The physical channels include data channels and control channels, and the data channels are further divided into fundamental channels and supplemental channels. Fundamental channels are used to transmit voice traffic, data traffic, high speed data, and other overhead information, and supplemental channels are used to transmit high speed data. The fundamental channels may be released when the remote stations are idle to more fully utilized the available capacity. The control channels are used to transmit paging and control messages and scheduling information. This abstract appears solely to satisfy requirements of 37 CFR 1.72 and is therefore not intended to be used for interpreting the scope of the claims.

    摘要: Techniques to support handover of a terminal from a source base station to a target base station are described. In one design, a determination is made whether a change in personality is requested by the terminal. If the answer is ‘Yes’, then the personality of the terminal may be switched by sending one or more appropriate messages. The connection and RLP for the terminal may be reset due to the change in personality. A buffer of data reported by the source base station as being served to the terminal (e.g., no NAK was sent) may be saved by a BSC/PCF. The buffer of data may be sent to the target base station when handover occurs. New data may thereafter be sent to the target base station. This buffer of duplicate data may avoid both loss of data and retransmission timeout by TCP during the handover.
