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： 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： Techniques to determine whether or not a terminal is under the coverage of a current wireless communication system (e.g., a packet data system) and to switch from the current system to another wireless communication system (e.g., a voice/data system). In one method, at least one measurement of at least one parameter for at least one base station in the current system is initially obtained. The measurement(s) may be SNR measurements. A metric is derived based on the measurement(s) and used (typically along with a metric threshold and a timer) to determine whether or not the terminal is within the coverage of the current system. A switch to another system is initiated if the terminal is deemed to be outside the coverage of the current system. The two systems provide at least one common service (e.g., packet data service).

摘要： A novel method and apparatus is disclosed for performing seamless handoff of a mobile station (MS) between Radio Access Networks (RANs) that use different types of wireless interfaces. The described embodiments enable an MS to handoff between different RANs without causing routing ambiguity, and without substantial loss of network data. Upon moving from the coverage area of a first RAN using a first wireless interface to the coverage area of a second RAN using a second wireless interface, an MS determines whether routing ambiguity may result from the change of RAN and, based on the determination, triggers a re-registration of its network address. A foreign agent (FA) within a packet data serving node (PDSN) monitors network address re-registrations in order to determine whether multiple RAN-PDSN (R-P) connections are being created for the same MS. Based on this determination, the PDSN terminates redundant R-P network connections resulting from movement of the MS between different RANs.

摘要： A user terminal establishes a session with a first access point (AP0) and obtains a token associated with modem configuration information used for radio communication. The user terminal thereafter establishes a connection with a second access point (AP1) by sending the token. AP1 receives the token, obtains the modem configuration information associated with the token, and initializes an air interface protocol stack with the modem configuration information to obtain a modem-specific protocol stack for the user terminal. AP1 sends a response indicating successful connection setup. The user terminal and AP1 thereafter communicate in accordance with the modem-specific protocol stack. AP1 may attempt to fetch the session for the user terminal from AP0. If this is successful, then AP1 updates the protocol stack with the session information to obtain a complete protocol stack for the user terminal. The user terminal and AP1 thereafter communicate with the complete protocol stack.

摘要： A control system (900, 1100) and various methods and apparatus for efficient communications of data across various protocol layers are disclosed. Generally, various aspects of the invention provide for efficient use of communication resources in a communication system (100) by efficiently controlling delay of a TCP acknowledgment message of reception of data from one communication protocol layer to another. Moreover, the delay of the TCP acknowledgment message and the message may be controlled to effect an efficient and consistent flow of data from a source end to a destination end, in particular, in case of encrypted communications.

摘要： Access terminal identification management providing a minimum distance between subnets before reusing subnet identifiers. Mobility criteria evaluation determines when to reassign an access terminal identifier. In one embodiment, the mobility criteria is whether any member of the active set for the access terminal belongs to an originating subnet. In an alternate embodiment, the criteria is whether the access terminal has traveled more than a minimum distance from the originating subnet. When a mobility criteria is violated, the access network assigns a new identifier. In one embodiment, the access terminal identifier is a long code mask based on a subnet identifier. Identifier management applies when crossing sector boundaries in a cellular system, and serves to reduce the ambiguity of mapping CC values to full UATI values, and to avoid overlapping assignments.

摘要： Techniques for efficient storage and retrieval of Preferred Roaming Lists are disclosed. In one aspect, PRL entries are stored in two tables. One table contains records that are common to two or more PRL entries. Another table stores any information that is unique to a PRL entry, as well as an indicator of which common record is associated with it. The common record is concatenated with the unique information to generate the uncompressed PRL entry. Various other aspects of the invention are also presented. These aspects have the benefit of reducing the memory requirements for storing a PRL. In addition, time required to download the compressed PRL is reduced.

摘要： This disclosure provides a method and apparatus for the communication of low delay data over multiple channels having different speed and latency and requiring a different amount of time to set up. In one embodiment, the transmitter removes duplicate data packets from a queue after a second channel, such as a dedicated channel is established. In an alternate embodiment, sequence numbers are assigned to data packets, allowing the receiver to identify duplicate packets and ignore the duplicates.
